Common moisture intrusions in Seattle homes
Seattle’s wet climate and certain detailing choices create predictable failure points:
- Flashing errors: Missing head flashing above windows/doors; no kick-out flashing where roofs meet walls; failed z-flashing at horizontal breaks
- End-grain exposure: Unsealed cut edges on fiber cement or wood; nail penetrations and miters not primed/painted
- Gutter overflow: Clogged or undersized gutters saturate fascia, soffits, and upper siding courses
- Siding-to-grade contact: Boards installed too close to soil, decks, or concrete pads wick water
- Aging sealants/paint: Cracked paint and failed caulk allow persistent water entry
- Improper clearances: Tight clearances to roofing, trim, or flashing that trap water
Our siding repair process
- Inspection and moisture mapping: Visual review, moisture meter readings, probe testing, and targeted test cuts where needed
- Source-first plan: We identify and fix the water entry (flashing, sealants, clearances, gutter issues) before closing the wall
- Targeted removal: Carefully remove damaged boards, trim, and any affected sheathing
- Structural remediation: Replace compromised sheathing or framing, treat adjacent wood as appropriate
- Correct detailing: Install/repair flashing, prime all cut ends, set proper clearances, use manufacturer-approved fasteners
- Finish and protection: Reinstall siding, caulk, and repaint to a clean break for a seamless finish
- Documentation: Photos, moisture readings, and a warranty-backed repair summary
Repair vs. replace — what’s right for your home?
Repair is the best value when:
- Damage is localized and the overall siding system is sound
- The moisture source is identifiable and correctable
- You’re planning to keep the current look and finish
- Widespread decay or delamination is present across multiple elevations
- Repeated failures indicate a systemic detailing issue
- You want to upgrade materials (e.g., from LP/older wood to fiber cement) or change aesthetics
We’ll show you side-by-side cost and timeline scenarios so you can decide with confidence.
