Garage Door Weather Seal Replacement in Seattle, WA

In a city that sees rain on well over a hundred days a year, the strip of rubber along the bottom of the garage door does a lot of work. When it hardens, cracks or tears, rain blows in under the door, leaves and pests follow, and the bottom of the door and its brackets sit in water.

What to Know About Garage Door Weather Seal Replacement in Seattle

Weather seal replacement is a small job with a large effect, and it is often the first thing worth doing on a door that is otherwise in good shape.

Replacing the bottom seal on a single door is the starting price. Double doors, rusted retainers, threshold strips and full perimeter seals cost more and are quoted on site.

We provide garage door weather seal replacement across Seattle and the nearby cities from our office on Stone Way North, and each area page below explains what is typical there, from damp alley garages to three-car Eastside garages.

Bottom, Side and Top Seals

The bottom seal sits in a retainer along the bottom edge of the door. Most modern doors take a replaceable T-style or bulb seal that slides into an aluminum retainer; older doors may have a nailed-on seal or a rusted retainer that needs replacing first. We match the profile to the door, or replace the retainer when it is too corroded to hold a new seal.

Where the slab is uneven or slopes, a standard seal leaves gaps. A thicker seal, a threshold strip bonded to the floor, or both, closes the gap. Around the sides and top, perimeter stop molding with a flexible flap seals against the face of the door and keeps out wind-driven rain.

Matched to the Door

Bottom seals are made in many profiles and widths for different retainers. We identify the retainer and fit the matching seal, so it stays in place and compresses evenly when the door closes.

A Seal Will Not Fix Everything

If water is coming in because the driveway slopes toward the garage or a drain is blocked, a seal helps but does not solve it. We say so, and suggest a threshold or drainage fix where it is the real answer.
