Understanding Trim Repair Costs in King County, WA
Trim, including window, door, fascia, and soffit trim, protects your home’s junctions and enhances its aesthetic. In King County, where rain and humidity are constant, trim is prone to rot and damage, especially in older homes in Capitol Hill or Proctor.

- Minor Repairs: $120 to $400, such as fixing window trim in Seattle’s Greenwood or door trim in Tacoma’s Stadium District. This includes patching small sections with epoxy and paint.
- Window or Door Trim Replacement: $300 to $800, for replacing rotted window trim in Bellevue’s Crossroads or exterior door trim in Federal Way. Costs vary based on material (e.g., wood at $0.50–$6 per linear foot, vinyl at $1–$3 per linear foot).
- Fascia or Soffit Repair: $500 to $1,200, like repairing fascia boards in Issaquah or soffits in Renton. Extensive damage can reach $2,875 for larger projects.
- Labor Rates: $65 to $105 per hour in King County, higher in urban areas like Downtown Seattle or Bellevue due to higher living costs.

- Choose Durable Materials: Opt for vinyl or composite trim in South Tacoma to reduce future maintenance costs.
Siding Replacement Costs in King County, WA
