Wood Garage Door Rot: Repair, Reface or Replace? A Seattle, WA Guide

Updated November 2026 · 8 min read

Peeling paint along the bottom of the door, a corner that gives when you press it, a door that sticks every January. On a wood garage door in Seattle, WA, those are the early signs of rot. This guide covers where rot starts, how to check for it, and how to weigh the three choices: repair the rail, reface the door, or replace it.

Why wood garage doors are common in Seattle

Seattle's housing is old by West Coast standards. The city's median home was built in 1976, and 22.8% of its homes date from before 1940 (American Community Survey 2020–2024), compared with about 11% for King County as a whole. Historic Seattle dates the Craftsman building boom to the years just after the 1909 Alaska-Yukon-Pacific Exposition, when streetcar neighborhoods like Wallingford, Ravenna, Mount Baker, West Seattle, Phinney Ridge and Greenwood were platted (KUOW). Many of those houses have a detached single-car garage off an alley or at the back of the lot, and a wood door, whether original, a 1970s replacement, or a newer carriage-style wood door chosen to match the house, is a natural fit.

Wood also costs the most to replace. Fixr lists wood door materials alone at $1,000–$3,500 for a single door and $2,000–$6,000 for a double, more than any other material it tracks. That's why the repair-or-replace question matters more for wood.

Where rot starts

Water does the damage, and water collects at the bottom. The usual pattern:

• The bottom rail, especially the lower edge and the end grain at each corner
• The lower ends of the vertical stiles, where they meet the bottom rail
• Behind peeling or cracked paint anywhere a horizontal surface holds water
• Around the bottom seal, where an old seal traps moisture against the wood
• Panels in the lowest section of a sectional wood door

Seattle's climate helps it along. Sea-Tac averages about 156 days a year with measurable rain, two-thirds of it November through March (NOAA 1991–2020 normals). A bottom rail sitting a quarter inch above a wet slab all winter wicks water into its end grain. A sprinkler that hits the door, or a downspout beside the jamb, does the same job in summer.

How to check a wood door for rot

You need a flashlight and an awl or thin screwdriver. With the door closed, press the tip gently into the bottom rail every foot or so and into each lower corner. Sound wood resists; rotted wood takes the point easily and may feel spongy. Look for bubbled paint, dark staining and gaps opening between rail and stile. Then watch the door run. A door swollen with water can drag in the tracks or push a roller out of line, which is how rot turns into an off-track repair.

Keep your hands away from the cables, bottom brackets and springs while you look. Torsion springs store enough energy to cause serious injury. Leave spring and cable work to a trained technician.

Option 1: repair the rail or the bottom section

If the rot is limited to the bottom rail or one corner and the rest of the door is sound and square, repair is usually the economical choice. Small soft spots can be dug out, treated with an epoxy consolidant, filled and repainted. A rail that's gone soft along its length can be cut out and replaced. On a sectional wood door, the whole bottom section can sometimes be replaced, which is where the published panel-replacement ranges come in: $150–$1,000 (Fixr, Jan 2025) or $440–$725 (This Old House, Mar 2026).

Ask what's included. A new bottom section usually means a new bottom seal and retainer, and often new bottom brackets if the old ones are rusted. If the door's weight changes, the springs may need rebalancing, which should be its own line on the estimate.

Option 2: reface or clad the door

Some companies offer to reface a sound wood door with new exterior boards or a composite overlay, keeping the frame, hardware and opener. It only makes sense if the frame has been checked and is dry and solid; cladding over rot hides the problem and adds weight. Treat it as a cosmetic option for a healthy door, not a cure for a rotten one.

Option 3: replace the door

Replacement is the honest answer when rot has reached the stiles or more than one section, when the door has been repaired before, when it's racked out of square, or when the hardware and springs are at the end of their life anyway. Two paths:

• New wood door. Keeps the historic look and can be built to a non-standard opening. Highest material cost, and it needs a finish schedule the installer should spell out for you. Ask how often they recommend recoating in this climate.
• Insulated steel or composite carriage-style door. Wood-look panels, optional top windows, far less upkeep, and lighter, which is easier on springs and openers. Fixr puts a new single steel door installed at $700–$2,000 and a double at $1,175–$4,075. Insulation helps in a damp, unheated detached garage.

Permits, HOAs and contracts

Most garage door repairs don't need a permit, but a new or resized opening, or new wiring for an opener, usually does. Seattle exempts minor repairs under $6,000 in six months that don't touch load-bearing framing; Bellevue, WA and King County exempt same-size door replacement; Issaquah requires a permit even for in-kind replacement (MyBuildingPermit tip sheet, June 2026). Exemptions may not apply on steep-slope or shoreline lots. Ask your installer or call your city's permit center.

Many Eastside and plateau neighborhoods have HOAs with architectural review. Issaquah Highlands, for example, requires an application before changing a garage door's style or color but not for a same-style, same-color replacement (IHCA FAQ). Check your own CC&Rs.

Washington requires garage door companies to be registered with the Department of Labor & Industries (L&I) as contractors. Look the company up on L&I's Verify a Contractor tool, get a written estimate for each option you're weighing, and ask for an itemized invoice when the work is done. To compare quotes on repair versus replacement, describe the door through the free quote form or call (877) 265-2390. A photo of the bottom rail helps.
