Whole-Home Weatherstripping
Whole-home weatherstripping is the perimeter sealing of every moving opening in the building envelope except exterior door thresholds — operable windows, attic-access panels, basement bulkheads, and the garage-to-house entry — installed with V-strip, foam tape, or rubber bulb matched to each opening, from $150 per opening and $450 for a typical 6-opening sweep. It is the fix for the double-hung window that whistles in a January wind, the bedroom that runs 5 degrees colder than the rest of the upstairs, the attic-access panel you can feel cold air dropping out of when you walk under it, the basement bulkhead that lets in dust from the side yard, the garage-to-house door that never sat right after the garage settled. Distinct from door-threshold weatherstripping, which lives under door repairs.

How Whole-Home Weatherstripping Works
Six steps from the room-by-room walk-through to the final compression check — the actual sequence we follow on every operable-opening weatherstrip sweep.
Room-by-Room Draft Walk-Through
Walk the house with a flashlight and the back of a hand on a cold or windy day to map every drafty opening — operable windows, attic access, basement bulkhead, garage-to-house door, specialty openings like pet doors and mail slots. Each leak gets sized and queued by material need.
Material Match Per Opening
Pick the right strip per opening from the truck — V-strip (brass or aluminum) for sash channels and sliding door perimeters that move daily, compression foam for meeting rails and static lip seals, rubber bulb for large irregular gaps like Bilco basement bulkheads. The wrong material at the right spot fails in a season.
Channel and Substrate Cleaning
Strip every old adhesive residue with denatured alcohol, wire-brush paint chips off sash channels, and dry-cloth the surfaces. Skipped prep is the single most common cause of a 90-day weatherstrip failure — new strip lifts because it never bonded to the substrate.
Operable Windows Stripped
V-strip pressed into double-hung side channels, compression foam applied at the meeting rail, fin-seal pile on slider edges, continuous bulb seal in casement and awning channels. Each sash worked open-and-closed three times after install to confirm no binding and clean compression.
Attic Hatch, Bulkhead, Garage-to-House Door
Foam tape on attic hatch frame lips, rubber bulb on basement bulkhead perimeters, three-sided foam-and-vinyl plus an automatic drop sweep on the garage-to-house door. The non-window openings get the same material discipline as the windows.
Flashlight and Dollar-Bill Compression Check
Run a flashlight along every sealed perimeter at night with someone inside watching for the beam, and try to pull a dollar bill out of every closed sash — no light, real resistance on the bill, no whistle on a windy day. Three quick post-install tests on every opening before the visit closes.
Whole-Home Weatherstripping Pricing
Final pricing depends on the opening count, the material per opening (V-strip vs foam vs rubber bulb), and whether sash adjustments or hardware are needed alongside the strip. Multi-opening visits are cheaper per opening than booking each separately. Request a free estimate for an accurate quote.

Why Choose a Professional for Whole-Home Weatherstripping?
Most window weatherstripping fails the same way — a previous owner stuffed cheap foam tape into the channel, the sash moved twice, and the tape pulled out and rolled up at the bottom. The right material for a moving sash is V-strip (brass on historic windows, aluminum on modern ones) that springs back to its shape over 10,000 close cycles. Foam tape belongs at the meeting rail where the sash sits in one position when closed. Pick the wrong material at either spot and the seal fails in one season. After a few hundred Seattle window-strip jobs across craftsman, Tudor, mid-century, and split-level homes, every common window type has a known material match. The truck carries all of it.

Customer Reviews
Recent whole-home weatherstripping reviews from verified Seattle customers.
1928 craftsman, every original double-hung window whistled in a strong westerly. Tech installed brass V-strip on every sash channel (10 windows), compression foam at every meeting rail, and replaced the failed pile strip on the kitchen casement. House sounds different in a windstorm now — quiet, the way it should be. Two seasons later, no failures.
The bedroom over the garage was always cold and we figured it was the door from the garage into the house letting in air. Tech confirmed it on a flashlight test, did a 3-sided compression strip on the frame plus an automatic drop-sweep at the threshold. Bedroom now matches the rest of the upstairs.
Attic hatch in the hallway ceiling dropped cold air every time someone walked under it. Tech installed foam strip around the frame lip and added two cabinet latches to make the gasket compress. Air drop is gone. Two-hour visit, $200 between this and the panel insulation.
Whole-home weatherstripping sweep on our 1965 rambler before our first Seattle winter. Tech walked the house, found 11 windows that needed work, did them all in one long visit. Did not try to sell us on the windows that were sealing fine. Honest scoping; the bedrooms that were drafty are no longer drafty.
Bilco bulkhead in the basement had been leaking dust and a little rainwater every winter. Tech replaced the perimeter rubber bulb seal — 90 minutes including hand-cleaning all the rust off the steel frame first. No more dust, no more water.
