1. Inspect and Seal Exterior Gaps
Check for Vulnerable Entry Points
Walk around your home’s exterior and examine areas where cold air can sneak in. Pay close attention to:
- Window and door frames
- Gaps around pipes and cables
- Foundation cracks
- Exterior wall penetrations (vents, spigots, etc.)
How to Seal Effectively
- Caulk any cracks or gaps less than 1/4-inch wide with exterior-grade caulk. Focus on joints, trim, and utility entry points.
- Expanding foam is ideal for larger gaps, especially where pipes or wires enter the home.
- Weatherstripping should be installed or replaced around doors and windows. Choose adhesive-backed foam or rubber strips for ease of installation.
Tip: Check for drafts on a breezy day by moving a lit incense stick around windows and doors. Watch for smoke movement to spot leaks.
2. Prepare Windows for Maximum Efficiency
Upgrade and Maintain Window Insulation
- Install window insulation film on single-pane or older windows. This clear plastic barrier reduces heat loss while letting light in.
- Hang thermal curtains or insulated drapes to block drafts at night. Open them during sunny days for passive heat gain.
- Replace cracked or missing glazing putty on older wood windows to seal glass panes securely.
Check and Repair Window Hardware
- Ensure locks latch tightly to minimize air leaks.
- Lubricate moving parts and adjust hinges as needed for a snug fit.
3. Safeguard Plumbing Against Freezing
Identify At-Risk Pipes
Focus on pipes located in:
- Unheated basements or crawl spaces
- Exterior walls
- Garages and attics
Steps to Protect Pipes
- Insulate exposed pipes with foam pipe sleeves or fiberglass wrap. Secure them with tape for full coverage.
- Disconnect and drain outdoor hoses. Shut off and drain exterior faucets or use insulated covers.
- During extreme cold, let faucets drip slightly to maintain water flow and reduce freezing risk.
- If possible, seal crawl space vents and doors to block drafts near plumbing.
Emergency Prep
- Know where your main water shutoff valve is located.
- Stock up on pipe insulation and heat tape for quick fixes if temperatures plunge suddenly.

How early in the season should I start checking for drafts with the incense stick trick to avoid getting caught by a sudden cold snap?
It’s best to check for drafts with the incense stick trick in early fall, ideally before nighttime temperatures start to dip. This gives you plenty of time to seal any leaks before the first cold snap arrives.
How long does it typically take to go through your whole checklist for a smaller home, and are there steps I can safely skip if I’m short on time or money?
For a smaller home, the full checklist usually takes about 4 to 6 hours. If you’re short on time or budget, focus on insulating pipes, sealing drafts, and checking your heating system—these steps offer the most protection against winter damage.
How often should I check for new drafts or leaks during the winter after following these steps, or is once enough?
It’s best to check for drafts or leaks at least once a month during winter, especially after any severe weather. Conditions can change, so occasional checks help catch new issues early.
What type of exterior-grade caulk would you recommend for sealing around old brick foundations, and are there any application tips to help it last through harsh winters?
For old brick foundations, use a high-quality silicone or polyurethane exterior caulk, as both remain flexible and weather-resistant. Clean and dry the area first, apply caulk when temperatures are above freezing, and tool it smoothly into joints for best durability.
What is the most cost-effective approach for insulating older windows if I’m on a tight budget and can’t replace them this year?
A very affordable way to insulate older windows is to use clear plastic window insulation kits, which you apply with double-sided tape and a hairdryer. Adding weatherstripping to gaps and using heavy curtains also helps keep out drafts.
Would you recommend caulking or expanding foam for sealing gaps around exterior pipes if the weather gets below freezing where I live?
For gaps around exterior pipes in freezing weather, caulking works well for smaller cracks, while expanding foam is better for larger gaps. Make sure whichever product you choose is rated for outdoor use and can withstand low temperatures.
For sealing exterior cracks, how do I know when to use caulk versus expanding foam? Are there situations where one is better than the other?
Use caulk for sealing small, narrow gaps or cracks, especially around windows and doors. Expanding foam works best for larger gaps and holes, such as those around pipes or in foundations. Choose based on the size and location of the crack.
If my budget is limited, which steps in your checklist would you prioritize first to prevent the most costly winter damage?
If your budget is tight, prioritize sealing gaps around windows and doors, insulating exposed pipes to prevent freezing, and checking your roof for loose shingles. These steps help avoid expensive repairs from leaks, drafts, and burst pipes.
How much of a difference do simple steps like sealing exterior gaps and using window film usually make on winter energy bills? I’m trying to figure out if it’s worth the time for my budget.
Sealing exterior gaps and applying window film can reduce heat loss significantly, often lowering winter energy bills by 10% or more. These steps are usually inexpensive and show a noticeable return, especially in drafty homes.
How early in the season should I start checking for exterior gaps and sealing them to beat the first deep freeze?
It’s best to start checking for exterior gaps and sealing them in early fall, ideally before temperatures consistently drop below 50°F. This gives you enough time to fix any issues before the first deep freeze arrives.
If I find foundation cracks while winterizing, should I address those immediately or wait until spring for bigger repairs?
If you notice foundation cracks, it’s wise to seal any small cracks right away to prevent water infiltration during winter. For major repairs, it’s usually best to wait until spring when conditions are better for lasting fixes.
For sealing foundation cracks, do I need a special type of caulk, or is the standard exterior-grade one good enough for concrete?
For sealing foundation cracks in concrete, use a concrete-specific or masonry caulk, which is designed to bond well and handle movement. Standard exterior-grade caulk may not adhere or last as long on concrete surfaces.
When checking for drafts with an incense stick, are there specific spots around window frames I should focus on, or is it just the corners?
It’s best to check both the corners and along the edges of the window frame, especially near the sash and where the frame meets the wall. Drafts can sneak in anywhere gaps or cracks are present.
How often should weatherstripping around doors and windows be replaced, and are there signs I should look for that indicate it’s no longer effective?
Weatherstripping usually lasts 5 to 10 years, but you should check it annually. Signs it needs replacing include drafts, visible cracks, peeling, or light showing around doors and windows. Replace it if you notice these issues to maintain energy efficiency.
For exterior gaps, how do I know when to use caulk versus expanding foam? Is one better for certain materials or locations around the house?
Use caulk for small gaps (less than 1/4 inch) around windows, doors, and trim, especially on wood or masonry. Expanding foam is better for larger gaps or cracks, like around pipes or basement openings. Always choose products rated for exterior use.
If I find multiple tiny foundation cracks, should I use exterior-grade caulk for all of them, or is it better to get them professionally assessed before sealing?
For multiple tiny foundation cracks, it’s wise to have a professional assess them first. Some cracks might indicate bigger issues, and sealing them with exterior-grade caulk could hide problems that need expert attention.
If I seal up all the drafts you mentioned, could that affect indoor air quality or ventilation during the winter?
Sealing drafts improves energy efficiency but can reduce fresh air flow. To maintain good indoor air quality, use kitchen and bathroom exhaust fans regularly and consider periodically airing out your home if weather allows.
Do you have any budget-friendly recommendations for insulating older single-pane windows if replacing them isn’t an option right now?

Can you clarify how to tell if a gap needs caulk or expanding foam, especially around older foundation cracks?
Use caulk for sealing small, narrow gaps—typically less than half an inch—especially where movement is expected, like between trim and masonry. For wider or irregular gaps, such as those in older foundation cracks, expanding foam provides better insulation and coverage.
Is there a certain type of caulk or weatherstripping that holds up best during really cold winters, or are the basic options at hardware stores fine?
For cold winters, silicone-based caulk is best since it stays flexible in low temperatures. For weatherstripping, closed-cell foam or rubber options tend to last longer. Basic products work, but those labeled for extreme weather offer better durability.
I have mostly older windows in my shop—does using window insulation film actually make a noticeable difference in heating costs, or is it mainly for comfort?
Using window insulation film on older windows can make a noticeable difference in both comfort and heating costs. It helps reduce drafts and heat loss, so your shop stays warmer and you may see lower energy bills during the winter.
Can you recommend the best way to check for foundation cracks during winter months when snow may be covering parts of my home’s exterior?
If snow is covering parts of your foundation, focus on checking exposed areas first. After heavy snow melts, inspect the entire foundation for new cracks or signs of moisture indoors, like basement dampness or musty odors.
What’s the most cost-effective way to insulate windows if I have a tight budget and mostly single-pane glass?
For single-pane windows on a tight budget, plastic window insulation kits are very effective. You can apply the clear film over your windows to reduce drafts, and it’s inexpensive and easy to install with just tape and a hairdryer.
For foundation cracks, is there a specific type of exterior-grade caulk you recommend, or does it depend on the material of the foundation?
The best exterior-grade caulk for foundation cracks does depend on your foundation’s material. For concrete or masonry, use a polyurethane or silicone-based caulk designed for masonry. Always check that the product is labeled for exterior use.
For larger gaps around pipes that enter the house, is expanding foam safe to use near wiring or should I use something else?
Expanding foam can be used around pipes, but if there’s electrical wiring nearby, it’s safest to use fire-resistant (fire-block) foam. Always check that the product is rated for use around electrical components.
If I already have some weatherstripping on my windows but still feel cold drafts, should I layer more on or is it better to replace the existing strips?
If you still feel drafts, it’s usually best to remove and replace the old weatherstripping. Over time, it can lose its effectiveness, and fresh strips will seal better than adding new layers on top.
How do I check for foundation cracks that might be letting cold air in, and should I call a pro if I spot anything bigger than normal caulking can handle?
Walk around your home’s exterior and interior basement walls, looking for visible cracks or gaps. If you find any crack wider than a quarter inch or one that’s growing, it’s best to call a professional for assessment and repairs.
If I find foundation cracks while checking the exterior, is it safe to seal them myself, or do some need professional repair?
Small, hairline cracks can often be sealed yourself with masonry caulk, but wider cracks (over 1/4 inch), horizontal cracks, or those with signs of shifting should be inspected and repaired by a professional to prevent serious issues.
Is there a certain type of exterior-grade caulk you recommend for super cold climates, or will any brand work as long as it’s labeled for outdoor use?
For super cold climates, it’s best to choose a high-quality silicone or polyurethane exterior caulk since these stay flexible and adhere well in freezing temperatures. Look for products labeled as suitable for extreme weather, not just general outdoor use.
If I find a large crack in my foundation while inspecting for drafts, is that something I should handle myself or call a professional before winter sets in?
A large crack in your foundation should be evaluated by a professional as soon as possible, especially before winter. DIY repairs may not address underlying issues, and prompt expert assessment helps prevent further damage during cold weather.
How often should weatherstripping be replaced to keep drafts out effectively during the winter?
Weatherstripping should generally be checked every year before winter starts. If it shows signs of wear, cracking, or is no longer sealing tightly, replace it to maintain effective draft protection.
If I already have expanding foam around my pipes from last year, how can I tell if it needs to be replaced or touched up before this winter?
Check the expanding foam for any cracks, gaps, or signs of crumbling. If it’s loose, brittle, or has pulled away from the pipes, remove damaged sections and reapply fresh foam to maintain proper insulation.
For sealing exterior gaps, is there a particular type of exterior-grade caulk you recommend for very cold climates, or will any standard product do the job?
For very cold climates, it’s best to use a high-quality silicone or polyurethane exterior-grade caulk. These remain flexible and adhere well even in low temperatures, unlike some standard latex caulks that can crack or shrink in extreme cold.
Is there a specific type of exterior-grade caulk you recommend for cold climates, or are most brands pretty similar in performance?
For cold climates, it’s best to use a silicone or polyurethane exterior-grade caulk, as these remain flexible and adhere well in low temperatures. Not all brands perform equally, so look for products labeled for extreme weather or cold application.
When using expanding foam for larger exterior gaps, is there a type that’s easier to remove if I need to access wires or pipes later on?
For easier future removal, look for low-expansion or minimally expanding foam labeled as ‘removable’ or ‘temporary.’ These are less dense and easier to cut away than standard high-expansion foams, making access to wires or pipes simpler if needed.
If my home is older with single-pane windows, will using insulation film be enough, or should I consider more permanent upgrades before winter hits?
Insulation film can help reduce drafts and heat loss temporarily, but for older homes with single-pane windows, upgrading to double-pane or storm windows offers much better long-term protection and energy savings. Consider permanent upgrades if your budget allows.
If my home already feels drafty even after sealing gaps, what additional steps would you suggest to improve comfort and keep energy bills down?
If drafts persist, consider adding insulation to your attic or walls, installing thermal curtains, and using draft stoppers on doors. Also, have your furnace serviced and check windows for possible upgrades to double glazing.
Can you recommend the most budget-friendly way to insulate single-pane windows without replacing them, especially for older homes?
One of the most budget-friendly ways is to use window insulation film kits, which create an insulating layer over the glass. Alternatively, adding weatherstripping and using heavy thermal curtains can also help reduce drafts and heat loss.
When checking for foundation cracks to seal, is it necessary to wait until the weather is dry, or can I use expanding foam on slightly damp surfaces?
It’s best to wait for dry weather before sealing foundation cracks. Expanding foam adheres much better to dry surfaces, ensuring a proper seal and longer-lasting protection against moisture and cold.
Is window insulation film effective enough for really old single-pane windows, or is it better to combine it with heavy thermal curtains?

The checklist highlights window plastic film kits and weatherstripping as the most cost-effective insulation options for older buildings. Both are affordable, easy to install, and can make a noticeable difference in reducing drafts and improving energy efficiency.
Can you explain how window insulation film compares to just using heavy curtains for dealing with drafty older windows?
Window insulation film creates an airtight seal over the glass, blocking drafts more effectively than heavy curtains alone. Heavy curtains help reduce heat loss but don’t stop air leaks. Using both together gives the best insulation for drafty windows.
When sealing exterior gaps, how can I tell if I should use caulk or expanding foam, especially around older brick foundations?
Use caulk for small gaps (less than 1/4 inch) and where flexibility is needed, like where different materials meet. Expanding foam is better for larger gaps or voids, but avoid using it where it might expand against delicate old bricks.
If I discover cracks in my foundation while inspecting for cold air leaks, is exterior-grade caulk enough or should I consult a pro?
If the cracks are very small, exterior-grade caulk can be a temporary fix. However, for wider or expanding cracks, it’s best to consult a professional to assess potential structural issues.
How early in the season should I start checking for exterior gaps and sealing them to avoid last-minute problems when temperatures drop?
It’s best to start checking for exterior gaps and sealing them in early fall, before temperatures drop significantly. This gives you enough time to address any issues before cold weather sets in.
For someone on a tight budget, are there affordable alternatives to buying weatherstripping for all my doors and windows?
Yes, you can use rolled-up towels or old blankets to block drafts at the base of doors and windows. Clear plastic film, bubble wrap, or even tape can also help insulate windows temporarily without much expense.
For sealing foundation cracks, is exterior caulk really enough, or should I consider something more heavy-duty if I spot wider gaps?
For small foundation cracks, exterior caulk works well. If you notice wider gaps, consider using hydraulic cement or a specialized concrete crack filler for a stronger, longer-lasting repair before finishing with caulk for weatherproofing.
How early in the season should I start checking for exterior gaps and sealing them to make sure I beat the first frost?
Aim to check for exterior gaps and seal them in early fall, ideally by late September. This gives you enough time to fix any issues before temperatures drop and the first frost arrives.
How can I tell if weatherstripping needs to be completely replaced, or if I can just add new adhesive strips over the old material?
Check if the weatherstripping is cracked, brittle, or no longer seals properly. If it’s damaged or coming loose, it’s best to remove and replace it. Adding new strips over old, worn material usually won’t be effective.
If I already have weatherstripping on my doors but still feel drafts, should I double up or is there a better way to stop the air leaks?
Instead of doubling up, check if the existing weatherstripping is worn, damaged, or improperly installed. Replacing it with a higher-quality or thicker type often seals gaps better. Also, inspect door sweeps and adjust thresholds for a tighter fit.
I’m wondering how often I should check exterior caulking and weatherstripping for wear—should this be a yearly thing or more often through the winter?
It’s best to inspect exterior caulking and weatherstripping at least once a year, ideally in the fall. If your area experiences harsh winters, a mid-winter check is also wise to catch any damage early.
For older windows that let in a lot of cold air, how effective is insulation film compared to installing thermal curtains, or should both be used together for best results?
Insulation film helps seal drafts and can noticeably reduce heat loss. Thermal curtains add another layer, blocking cold and keeping warmth in. Using both together is most effective, especially for older windows with significant drafts.
For sealing gaps around exterior pipes and cables, is there a certain type or brand of expanding foam you recommend for extreme cold climates?
For extreme cold climates, look for closed-cell, minimal-expansion polyurethane foam specifically rated for outdoor use and low temperatures. Brands like Great Stuff Pro Gaps & Cracks are commonly used. Always check the product label to ensure it remains flexible and insulating in freezing conditions.
How soon before the first freeze should I start working through this checklist to make sure my home is ready in time?
It’s best to start winterizing your home about 2 to 4 weeks before the first expected freeze. This gives you enough time to complete each step without rushing and ensures you’re well-prepared for sudden cold snaps.
Can you recommend the best type of exterior caulk for really cold climates? I’m worried about it freezing before it sets when sealing gaps this time of year.
For really cold climates, choose a silicone-based exterior caulk labeled for low-temperature application, as it remains flexible and can cure in temperatures as low as -20°F. Make sure surfaces are dry and follow the manufacturer’s instructions for best results.
If I already have weatherstripping on my windows, how can I tell if it’s still doing its job or if I should replace it before winter?
Check for drafts by feeling around the window edges on a windy day or using a lit candle to spot flickering. If you notice air leaks, cracks, or the weatherstripping is brittle or misshapen, it’s time to replace it.
For sealing larger gaps around exterior pipes, do you have any tips on making expanding foam look neat and avoid overfilling?
Use painter’s tape around the gap to create a clean edge before applying expanding foam. Apply the foam slowly to avoid overfilling, and once it cures, trim any excess with a utility knife for a tidy finish.
How do you know if a crack in the foundation is serious enough to need more than just exterior-grade caulk?
If a crack is wider than 1/4 inch, growing over time, or causes noticeable movement, it could indicate a structural issue that needs a professional inspection, not just caulking. Also, look for moisture, uneven floors, or doors that stick nearby.
Do you have suggestions for affordable window insulation film brands, or will generic films work about the same as more expensive options for older windows?
Generic window insulation films often work just as well as pricier brands for older windows. Brands like Frost King and Duck are affordable and commonly available, but any well-reviewed generic film should provide effective insulation if installed carefully.
If I have drafty spots around my foundation, should I address those before winter or can it wait until spring without causing damage?
It’s best to address drafty spots around your foundation before winter. Sealing them now prevents cold air, moisture, and even pests from entering your home, which can help avoid potential damage or higher heating costs during the colder months.
If I find a draft using the incense stick trick, how do I know whether to use weatherstripping or caulk to fix it?
If the draft is coming through a movable joint like a window sash or door, use weatherstripping. If it’s coming through a stationary crack or gap, like along window frames or baseboards, caulk is the better choice.
For weatherstripping doors, are there certain types that work better for old wooden frames versus newer metal doors, or does the adhesive foam fit all?
Adhesive foam weatherstripping can fit most doors, but for old wooden frames, felt or V-strip may seal gaps better. For newer metal doors, silicone or rubber strips usually last longer and adhere well. Choose based on the door material and gap size.
When sealing exterior gaps, how do I know when to use caulk versus expanding foam, especially for cracks around utility entry points?
Use caulk for small gaps or cracks under half an inch, especially where flexibility is needed, such as around window or door frames. For larger gaps around utility entry points, expanding foam is better because it fills bigger spaces and insulates well.
How do I know if expanding foam or caulk is better for the gaps around my window frames? I have a few wider cracks and I’m not sure what to use.
For narrow or small gaps around window frames, caulk is best because it seals and remains flexible. For wider cracks, expanding foam works better since it fills larger spaces and provides better insulation.
Is there a big difference between adhesive-backed foam and rubber weatherstripping when it comes to keeping out cold air or lasting through the winter?
Rubber weatherstripping generally creates a better seal and lasts longer through winter conditions than adhesive-backed foam, which can compress or lose stickiness over time. Foam is easier to install, but rubber is more durable and effective for blocking cold air.
How do I know when it’s better to replace old weatherstripping instead of just adding more or repairing it?
If your weatherstripping is cracked, brittle, or no longer seals gaps even after repairs, it’s best to replace it. Simply adding more won’t restore its effectiveness if the material is worn or damaged.
When sealing exterior gaps, do you recommend a specific type or brand of caulk for areas with extreme cold and snow exposure?
For extreme cold and snow exposure, use a high-quality silicone or polyurethane caulk, as these types remain flexible and adhere well in low temperatures. Brands like GE Silicone II or DAP Dynaflex Ultra are reliable options for tough winter conditions.
If I’m on a tight budget, which step in your checklist would make the biggest difference in preventing energy loss and high heating bills?
Sealing drafts around windows and doors with inexpensive weatherstripping or caulk can make the biggest difference. This simple step keeps warm air inside, reduces energy loss, and helps lower your heating bills without costing much.
When inspecting for exterior gaps, are there certain types of foundation cracks that should be handled by a professional instead of just sealing them myself?
Yes, if you notice foundation cracks wider than a quarter inch, horizontal cracks, or any cracks with signs of shifting or water intrusion, it’s best to consult a professional rather than sealing them yourself.
How often should I reapply caulk to exterior gaps to ensure it holds up through multiple winters?
It’s best to check and reapply exterior caulk every 2 to 3 years, or sooner if you notice cracks or gaps. Inspect it every fall to ensure it remains sealed before winter sets in.
For sealing exterior gaps, how do I tell if I should use caulk or expanding foam on a particular spot, especially around pipes and wires?
Use caulk for small gaps (less than 1/4 inch) or where flexibility is needed, like around window frames. Expanding foam works better for larger gaps or irregular spaces, especially around pipes and wires where more insulation is required.
Are there certain types of weatherstripping that last longer or work better for older wooden windows?
For older wooden windows, V-strip (tension seal) and silicone rubber weatherstripping are often the most durable and effective. These types adapt well to irregular surfaces and withstand frequent use, making them a great choice for older frames.
If I’m on a tight budget, which of these sealing steps would give me the most noticeable difference in warmth and energy savings right away?

Use caulk for smaller gaps (less than 1/4 inch) around pipes and wires, especially where flexibility is needed. Expanding foam works better for larger gaps and provides stronger insulation, making it more effective for long-term draft prevention.
I live in an older house with a lot of drafty windows. How much of a difference does using window insulation film really make in heating bills?
Using window insulation film on drafty windows can noticeably reduce heat loss, often lowering heating bills by 10–20 percent. It helps keep warm air inside, making older homes more comfortable and energy efficient during the winter.
Do you recommend weatherstripping for interior doors as well, or is it just most important for exterior doors and windows?
Weatherstripping is most important for exterior doors and windows to keep cold air out. For interior doors, it’s usually not necessary unless you’re trying to isolate a specific room, like preventing drafts in a rarely used guest room.
For sealing gaps around exterior pipes, is expanding foam safe to use near plumbing that might freeze or does it need special precautions?
Expanding foam is generally safe for sealing gaps around exterior pipes and helps insulate them. Just make sure it’s labeled for use with plumbing and for exterior conditions. For pipes prone to freezing, also add pipe insulation for extra protection.
How early in the season should I start inspecting and sealing exterior gaps to make sure I’m not too late if an early freeze hits?
It’s best to start inspecting and sealing exterior gaps in early fall, ideally by late September or early October, so you have plenty of time to address any issues before unexpected cold snaps occur.
How soon before winter do you recommend starting this winterizing checklist to make sure everything’s done in time?
It’s best to start your winterizing checklist about 4 to 6 weeks before the cold weather typically arrives in your area. This gives you plenty of time to complete tasks and address any unexpected issues.
Do you have any recommendations for sealing foundation cracks that are wider than 1/4 inch, or should those be handled by a professional?
For foundation cracks wider than 1/4 inch, it’s usually best to consult a professional. These cracks can indicate structural issues, and DIY repairs may not address the underlying problem. A professional can assess and repair them safely.
If my home has older single-pane windows, does the window insulation film really make a noticeable difference, or should I consider other options for better efficiency?
Window insulation film can make a noticeable difference by reducing drafts and heat loss, especially with single-pane windows. For even better efficiency, consider adding heavy curtains or eventually upgrading to double-pane or storm windows.
Are there any specific types of exterior-grade caulk that work better in really cold climates, or are they all pretty similar in performance?
For very cold climates, look for silicone or polyurethane exterior-grade caulks labeled as suitable for low temperatures. These types remain flexible and adhere better in extreme cold compared to standard latex caulks.
If I have older single-pane windows, is installing insulation film enough or should I consider storm windows too? I’m trying to balance comfort and cost this winter.
Insulation film is a quick, affordable way to reduce drafts and heat loss with single-pane windows. For even better insulation and comfort, adding storm windows is more effective, though it costs more up front. Using both is ideal if your budget allows.
How early in the season should I start inspecting and sealing gaps to make sure I’m ahead of any potential cold snaps?
It’s best to start inspecting and sealing gaps in early fall, ideally before temperatures drop. This way, you’ll have plenty of time to address any issues before the first cold snap arrives.
