Seattle Trim Repair Pricing Guide 2026

Trim repair costs in Seattle are not a simple price per linear foot. Our climate rots wood in patterns a dry region never sees, so the bill covers more than the damage you can see. It also covers the hidden rot, the failed flashing (the metal that steers water out of a seam), and the structural work that Seattle’s 156 rainy days set in motion. This guide gives real cost ranges, shows what pushes an estimate up or down, and helps you tell a minor patch from a full remediation.

Average Trim Repair Costs in Seattle

What you pay depends on scope, material, how hard the work is to reach, and how much hidden damage turns up once we open things up. Projects tend to fall into three groups.

Minor Repairs ($300-$800)

Minor repairs handle small, local damage, where the rot is limited to a short run of trim and the framing behind it is still solid. Think patching one rotted window sill, swapping a short piece of corner board, or fixing fascia (the board along the roof edge that holds your gutters) in a single spot. There is little to tear out and not much material, so we often finish in a day.

On minor repairs, labor is 60-70 percent of the bill and material is the rest. Matching the paint or finish adds $100-200 on top.

Moderate Repairs ($1,200-$2,500)

Moderate damage means longer runs of trim, several spots, or rot that has reached the sheathing (the panels under the siding) but not the main framing. That looks like new casings on several windows, 10-20 linear feet of fascia, or a water-damaged door trim and threshold.

These jobs take more tear-out, new flashing done right, and careful drainage so the problem does not come back. Figure 2-4 days, and sometimes a painter or siding crew if the material next door has to come off too.

Extensive Repairs ($4,500-$8,000+)

Extensive damage is when dry rot, the fungus that eats wet wood, has spread into the wall studs, floor joists, or roof framing. It usually hits several spots, brings structural work, and can trigger a permit once you start replacing framing. At this level you see full fascia and soffit (the underside of the roof overhang) replacement on one or more sides of the house, reframing a rotted window or door opening, or clearing dry rot that has run through several wall cavities.

Plan on 1-2 weeks, plus scaffolding, special equipment, and several trades working in sequence. When a lot of framing has to be replaced, this kind of structural repair sometimes runs past $8,000.

Cost by Trim Type and Material

Material drives both the first bill and how long the repair lasts. Here are typical installed costs for the common trim materials we use in Seattle.

Those per-foot numbers cover material, labor, fasteners, and basic caulking. They do not cover flashing, the paint finish, or any structural repair to the framing behind the trim.

Key Cost Drivers for Seattle Trim Repairs

A few things move the final number beyond footage and material.

Extent and Location of Damage

The size of the damage drives material and labor, of course. But where it sits matters just as much. Trim at a first-floor window is cheap next to the same rot at a third-floor gable end, where we need scaffolding and fall protection to reach it.

In Seattle, damage is rarely alone. Rot on the trim usually reaches into the sheathing or framing behind it. A job that starts as a simple trim swap grows the moment we pull the board and find more rot. That is why an honest estimate needs an on-site look; we assume the damage runs further than it shows, because here it usually does.

Material Choice

Better material costs more now and less over its life. Putting PVC or fiber cement on the exposed spots, north-facing fascia or a shaded window casing, adds 30-50 percent to material up front. It also ends rot repairs in those spots for good.

Here is how we steer that choice. If you plan to stay, rot-proof material on the vulnerable trim pays for itself within 10-15 years in repairs you never make. If you are fixing the house to sell, lower-cost painted wood is often the smarter spend.

Accessibility and Complexity

Multi-story walls, steep roofs, and tight access all add labor and equipment. Scaffolding rents for $300-800 per week, depending on height and size. A boom lift for tall or awkward work can add $500-1,200 per day.

Older homes with fancy trim profiles need custom milling or hand-shaping to match. That drives up material and labor. Matching complex crown molding or a corbel can cost two or three times what plain flat trim would.

Additional Services

Trim repair usually pulls in related work, either to fix the cause or to finish the job right. New flashing adds $150-400 per window or door. Repairing or replacing siding next to the trim adds $300-1,500, depending on how much. Matching and applying the finish adds $200-600 on a small area, more for a full wall.

If the frames themselves are rotted, the window may have to go too, at $500-1,500 each. When structural work needs a permit, set aside $200-500 for fees and inspection.

Geographic Location Within King County

Labor and delivery costs shift across King County. City neighborhoods can run a premium, thanks to parking rules, travel time, and tougher permitting. Suburbs like Bellevue, Kirkland, and Redmond usually land mid-range. Rural or hard-to-reach properties out past the county edge can add travel and delivery fees.

Cost by Common Repair Type

Window and Door Trim Repair

Window and door trim is one of the most common repairs we do here, because flashing fails and caulk breaks down. Replacing trim on one window usually runs $400-900, material, labor, flashing, and paint included. Door trim runs $500-1,200 per door, more for exterior doors that need threshold and weatherstripping work.

Do several windows at once and the per-window price usually drops. New casings on 4-6 windows might run $1,800-3,500 in total, depending on material and access.

Fascia and Soffit Repair

Fascia boards cap the roof edge and hold your gutters. They are out in the weather and take a beating here. Replacing fascia usually runs $12-28 per linear foot installed, more for thick or custom-profile boards.

Soffit work usually rides along with fascia. Vented soffit panels run $8-18 per linear foot installed. Doing the full fascia and soffit on one side of a typical single-story home, 30-40 linear feet, comes to $1,500-3,200.

Dry Rot Remediation

Clearing dry rot means cutting out every bit of affected wood, treating the wood around it with fungicide or borate, and rebuilding with sound material. The cost tracks the spread. A contained repair over 5-10 linear feet of trim runs $800-1,800. Dry rot through several wall cavities and into the framing can reach $5,000-10,000.

Here, dry rot almost always needs more work than the surface shows, because the fungus travels through wall cavities and even across brick and plaster to find more wood. We use a moisture meter and probe the wood to pin down the real scope before we start.

DIY vs Professional Trim Repair

Doing it yourself saves labor but carries risk. A homeowner with carpentry skills and the right tools can handle a minor cosmetic fix, like one short piece of trim on a reachable first-floor window. Materials for a small DIY repair usually run $50-200.

But most trim damage in Seattle hides rot, failed flashing, or a structural problem that takes experience to read and fix. DIY jobs tend to miss the real source of the water, so the same spot fails again within 1-3 years. Flashing set wrong, or the wrong fastener, can make the moisture worse than before.

A professional repair finds the cause, gets the flashing and drainage right, picks material to match the exposure, and stands behind the work. For moderate or heavy damage, that beats a DIY fix that fails and has to be redone, nearly every time on cost over the long run.

Getting Accurate Estimates

A trim estimate needs an on-site look, because hidden damage does not show in a photo or a description. We will not quote trim from pictures; it is not us being difficult, it is that the rot behind the board sets the real price. When you ask for estimates, tell each contractor where the visible damage is, any moisture history, and the home’s age and construction.

Expect line items for material, labor, flashing, fasteners, caulking, and finish. An itemized estimate is the only way to compare bids fairly and see where two contractors actually differ.

Ask how each bid handles hidden damage. Many price only the visible rot and write any extra as a change order later. Others fold a contingency into the base number. We prefer the second way: it is better to build the unknown into the price than to surprise you once the wall is open. How a contractor prices that tells you a lot about how the job will go.

Check whether permits are in the price if structural work is likely. Confirm the warranty too: a solid contractor backs both material and labor, usually for 1-3 years.
