The cost to install weatherstripping in Seattle ranges from $120 to $730, with most homeowners paying around $370. Your actual cost depends on several factors specific to your home and the Seattle-Tacoma market.
Each door or window that needs weatherstripping adds material and labor — most homes have 15–30 openings to seal.
Self-adhesive foam is cheapest ($1–$3 per door) but wears fastest. V-strip ($3–$5) lasts longer. Door sweeps ($8–$15) are essential for the bottom gap.
Removing old, degraded weatherstripping and cleaning the surface before applying new material adds time to each opening.
Door bottom seals or sweeps are often the biggest air leak source. Automatic door bottoms ($20–$40) seal when the door closes and retract when it opens.
Caulking around window and door frames complements weatherstripping by sealing gaps in the fixed frame. A full air-sealing job includes both.
The Pacific Northwest has moderate to high labor costs. Rain affects exterior scheduling October through April. Green building practices are common and many contractors specialize in energy-efficient work.
Weatherstripping installation in Seattle generally does not require a permit for standard installations. Check with your local building department if your project involves panel work or structural changes.
Moderate insulation levels are usually sufficient. Focus on air sealing for the biggest impact on energy bills rather than maximizing R-value.
Handy homeowners with basic tools can handle straightforward weatherstripping installation. If your project involves the panel, new circuits, or gas lines, hire a licensed pro. DIY can save $154–$198 in labor.

Most weatherstripping installation projects in Seattle take 1–1 day to complete. The timeline depends on project scope, contractor availability in the Seattle-Tacoma metro area, and seasonal demand. Scheduling during Seattle's off-peak season (typically winter months) can reduce wait times and may lower costs.
Weatherstripping all doors and windows typically reduces heating and cooling costs by 5–15%, saving $50–$200 per year for most homes. It's one of the cheapest and highest-ROI energy improvements you can make. Combined with caulking, savings can reach 20%.
Most weatherstripping lasts 3–7 years depending on material and usage. Check annually by closing a door on a piece of paper — if you can pull the paper out easily, the weatherstrip needs replacement. Replace any that's visibly cracked, compressed, or peeling.
