- Estimated Cost: $50–$120 per window (film only)
Reinforcing Doors for High Winds and Flying Debris
Door Bracing and Reinforcement Kits
Standard exterior doors often fail in high winds. Install a door reinforcement kit, which typically includes longer hinge screws, deadbolt reinforcements, and strike plate upgrades. For double doors or patio sliders, add head and foot bolts.
- Tools Needed: Power drill, screwdriver, wrench
- Estimated Cost: $100–$400 per door
Garage Door Strengthening
Garage doors are a weak point in hurricanes and tornadoes. Retrofit kits add horizontal and vertical bracing. For DIYers, installation usually involves bolting steel supports to the door’s structure and securing tracks.
- Tools Needed: Socket set, drill, level, safety glasses
- Estimated Cost: $200–$500 per door
Roof and Attic: Preventing Uplift and Water Intrusion
Installing Hurricane Straps or Clips
Metal hurricane straps connect rafters/trusses to wall plates, dramatically increasing wind resistance. Access is easiest via the attic. Work methodically, wearing gloves and eye protection.
- Tools Needed: Hammer, drill/driver, ladder, metal snips
- Estimated Cost: $250–$900 (materials for average-size home)
Inspecting and Sealing Roof Penetrations
Check for loose shingles, damaged flashing, or gaps around vents. Use roof sealant or flashing tape to block water intrusion. Prioritize repairs at eaves, ridges, and valleys.
- Tools Needed: Caulking gun, roofing cement, putty knife
- Estimated Cost: $50–$200
Attic Vent Protection
Install vent covers or baffles to keep wind-driven rain and embers out during storms or wildfires. Ensure attic vents are securely fastened and undamaged.
- Tools Needed: Screwdriver, drill, tin snips
- Estimated Cost: $40–$150
Flood and Water Intrusion Defenses
Sandbags and Temporary Flood Barriers
For homes in flood zones, pre-filled sandbags or quick-deploy barriers can shield doors, garages, and low windows. Store them dry and accessible for rapid deployment.
- Tools Needed: Shovel (if filling bags), gloves
- Estimated Cost: $50–$300 per entry point
Basement and Foundation Sealing
Apply waterproof masonry sealer to basement walls and floors. Fill cracks with hydraulic cement. Install window well covers to block debris and water.
- Tools Needed: Paint roller, brush, crack filler, utility knife
- Estimated Cost: $200–$750
Sump Pump Installation and Maintenance
Sump pumps are essential for flood-prone basements. Many homeowners can install basic models with clear instructions. Regularly test and clean your pump before storm season.
- Tools Needed: Drill, pipe wrench, level, bucket
- Estimated Cost: $150–$500 (DIY install)
Gutters, Drains, and Exterior Water Management
Cleaning and Upgrading Gutters
Clogged gutters cause roof and foundation leaks. Clean them at least twice a year, and install gutter guards to minimize debris build-up. Check downspouts for secure attachments and clear flow.
- Tools Needed: Ladder, gloves, gutter scoop, garden hose
- Estimated Cost: $50–$150 (cleaning & minor repairs), $200–$500 (gutter guards)
Improving Site Drainage
Grade soil so water flows away from the foundation. Add extensions to downspouts to direct runoff at least 6 feet from the house. For persistent issues, consider a French drain (DIY kits available).
