Door Installation in Seattle: What Entry, Patio and Garage Doors Cost, and the Rules That Come With Them

What door installation costs in Seattle

The price table adjusts national installed prices for Seattle. The U.S. Army Corps of Engineers puts construction costs in the Seattle area at 1.15 times the national average, based on the average of Tacoma (1.07) and Puget Sound bases (1.21). That factor is why a door quoted at the national average costs more here.

Estimates for 2026, including labor and standard parts. Seattle prices use a construction cost factor of 1.15 (US average = 1.00) from the U.S. Army Corps of Engineers Area Cost Factors, based on drawn from Tacoma (1.07) and Puget Sound bases (1.21). Your quote depends on access, materials and the condition of the home.

The entry door line covers a standard pre-hung door in an existing opening. Material moves the price: steel at the low end, fiberglass in the middle, solid wood at the top. Sidelights, a wider opening and rot at the sill all push a quote up.

What raises a door quote in Seattle:

• A wider opening. Going from a single door to a double, or from a slider to a multi-slide wall, means a new header and plan review.
• Rot at the sill or the frame. Constant wet weather finds soft wood. A new frame adds $150 to $690 at Seattle prices.
• Salt air near the water. Hardware and fasteners need a corrosion-resistant finish, which costs more than builder-grade steel.

Door types for Puget Sound homes

Entry doors

Fiberglass resists dents, does not swell and can look like wood. Steel costs less and holds paint well. Wood suits the Craftsman and Tudor houses common around Seattle but needs refinishing every few years here. Our entry doors guide covers materials and hardware. If the door faces the weather, ask what the finish warranty says about constant moisture.

Patio, French and multi-slide doors

A sliding door saves floor space. French doors give a wide traditional opening, and multi-slide or bi-fold doors can open most of a wall. Compare them in our guides to patio doors, French doors and multi-slide doors. Everett's damp climate is the reason exterior work here needs to protect the house from moisture (Energy Exteriors NW). A wide door with a flush threshold needs a sill pan, flashing and drainage that handle a wet fall. Ask how the installer will handle water at the bottom of the opening.

Garage doors

A garage door replacement holds value at resale. Our garage doors guide covers materials and openers. The federal reversing rule applies to every automatic opener.

Glass in doors: safety and energy

Safety glass

Glass in doors that people walk through is a hazardous location under the residential code, so it must be tempered or laminated safety glass. Sidelights and glass panels next to a door usually fall under the same rule when the glass sits low. Ask your installer to confirm which panels are safety glass before the door is ordered.

Energy ratings

Washington follows the state energy code for replacement doors, and glazed doors are rated like windows. Look for a National Fenestration Rating Council label on the door and check the U-factor and solar heat gain rating. Seattle is mild and cloudy, so heat loss matters more than summer sun. Watch the U-factor. Our energy-efficient windows guide explains how the ratings work, and the same labels apply to glass doors.

Weather, wind and salt air

Puget Sound weather is the main reason doors fail early here. Wind-driven rain pushes water against the door face and into the sill. Marine air corrodes cheap hinges, locksets and threshold screws. Everett's damp weather makes updated exterior products important for protecting the home (Energy Exteriors NW).

What that means for your door:

• A sill pan and proper flashing under the threshold, not caulk alone.
• Stainless or coated fasteners and hardware near the water.
• A door that closes tight against its weatherstripping, with an adjustable threshold.
• A covered porch or an awning over a west-facing door if the house has none.

Ask the installer how the door is anchored into the framing. A door nailed only through the trim will move in a wind storm and leak at the corners.

Garage door rules

Auto-reverse

Federal rules require automatic residential garage door openers to meet entrapment protection standards, which make the door stop and reverse. After installation, the installer should test the reversing function and the photo eyes in front of you.

The door between the garage and the house

The door from an attached garage into the house is a fire separation. The code allows a solid wood or steel door of set thickness, or a 20-minute fire-rated door, and it must be self-closing and self-latching. A hollow-core interior door does not qualify, so check this when you replace it.

Do you need a permit for a new door in Seattle?

It depends on which city you live in and whether the opening changes. A same-size swap in the same opening is usually exempt. Widening an opening for a double, French or multi-slide door is structural and needs a permit with plan review.

In Bellevue, a permit with plan review is required for installing or moving an exterior door, including making an existing opening wider, and no permit is required for replacements of the same size in the same location (City of Bellevue). Redmond exempts removal and replacement of interior doors in existing door frames (City of Redmond). Redmond bases permit fees on the value of construction, and a final inspection is required to close the permit (City of Redmond).

Seattle's Department of Construction and Inspections raised most fees 6.5% on January 1, 2025, and its base hourly rate is now $274 per hour (SDCI). No permit is issued until the fees are paid, and a financially responsible party, usually the property owner, is named on the permit and liable for the charges (2025 Fee Subtitle).

Everett Permit Services processes all required permits for construction in the city and moved to the 2nd floor of the Everett Municipal Building at 2930 Wetmore Avenue (City of Everett). Tacoma takes building permit applications through its Tacoma Permits system, which requires an account (City of Tacoma). Renton requires a building permit to alter, replace or install a building structure or its electrical, gas, mechanical or plumbing systems (City of Renton).

Outside the cities, the county issues the permit. King County handles permits for unincorporated areas and takes most applications online through MyBuildingPermit.com (King County). Pierce County requires a permit to construct or renovate a residential structure except for listed exemptions (Pierce County).

Washington is the only state in this metro, so the state residential code applies across Seattle, Bellevue, Redmond, Kirkland, Tacoma, Everett and Renton. Each city sets its own permit list and fees, so confirm with your city before you order a door.

Lead paint around old door frames

Many Seattle houses were built before 1978, and door frames and trim often carry paint from that era. Under the EPA's Renovation, Repair and Painting rule, paid work that disturbs painted surfaces in a pre-1978 home needs a certified firm and lead-safe practices (EPA). Pulling an old frame and its casing disturbs a lot of painted surface.

Washington adds its own rules. Contractors doing renovation, repair or painting work on pre-1978 homes need RRP certification, and firms pay a $25 application fee to the Department of Commerce (Washington Department of Commerce). EPA runs the federal program in Washington and recommends hiring a lead-safe certified contractor (EPA). Ask for the firm's RRP certificate before work starts.
