West Seattle replace rotted deck boards

Homeowner’s Issue

West Seattle houses face a specific set of deck problems: long, damp winters, salt spray near Alki, and heavy shade from mature maples around Admiral and Lincoln Park. Our soils are a mix of glacial till and compacted clay in many yards, so water sits longer and under-deck ventilation is poor. North-facing and canyon-like properties around Fauntleroy and High Point get less sun, so moss, algae, and fungal decay set in faster than neighbors expect.

Rainfall and humidity push untreated or poorly finished boards toward rot within a few seasons. Slopes and terraces create drainage points where joists and board ends trap moisture. HOAs and curb appeal standards in parts of West Seattle can force visible repairs on a tight timeline. Practically, that means you’ll see soft spots, cupping, dark streaks, and loose fasteners; if you ignore them, structural problems and safety hazards follow. We focus on diagnosing the moisture source, not just swapping boards—fix the drainage and wind/dry exposure, and your new deck lasts longer. We use only sustainable methods: salvaging what we can, recycling old lumber, and using low‑VOC finishes and long‑life materials instead of herbicides or toxic treatments.

Our Quality Service

We assess the whole deck and surrounding grades, then replace rotted boards with materials suited to West Seattle’s microclimate. Typical tools and methods:

  • moisture meter, pry bars, circular saw, screw gun with long-life stainless fasteners
  • selective removal to preserve good boards and minimize waste
  • improved ventilation and flashing at critical seams
  • low‑VOC sealers or natural oil finishes; composite or cedar options available

Timeline: small deck (under 200 sq ft) — 1 day; average deck — 1–2 days; complex jobs or railing replacements — 2–3 days. We schedule around weather windows and summer drying periods to get seams sealed properly. We never use herbicides; maintenance is mechanical, cultural, and organic.

Benefits:

  • safer walking surfaces and stronger fastenings
  • reduced long‑term maintenance
  • better curb appeal for resale or HOA compliance
  • sustainable disposal and material choices

What’s Included

  • full inspection and written condition report
  • selective removal of rotted boards
  • install new boards cut to fit and fastened with stainless or coated screws
  • basic spot sanding and application of low‑VOC sealer (if selected)
  • haul-away of debris (options below)

Options / Upgrades

  • board material: pressure‑treated, cedar, or low‑maintenance composite
  • low‑VOC stain or natural oil finish
  • extra flashing, joist caps, or under-deck ventilation improvements
  • rail replacement or tighten/refasten existing railings
  • haul-away to landfill vs. green‑bin/yard‑waste recycling
  • organic algae & moss cleaning (mechanical + biodegradable cleaners)

Before & After / Expectations

Expect some noise and sawdust while we work. We protect adjacent plantings and patios, but access to the deck should be clear (gate unlocked or an arranged entry). If joists or ledger are compromised, we’ll flag that during inspection and quote repairs separately.

Debris handling: we segregate salvageable boards, recycle what we can, and offer green‑waste haul-away. Small jobs usually finished same day; plan for 24–48 hours if finishing/sealing is required and weather cooperates.

Care tips for West Seattle:

  • reapply oil or low‑VOC sealant in a dry spell (late spring/early summer is ideal)
  • keep soil and mulch pulled back from deck edges to improve airflow
  • sweep and remove organic debris monthly in rainy months
  • for shaded areas, scrub moss mechanically and let sun/dry cycles do the rest

FAQs

  • How soon can you start?
    • We aim for a photo estimate within 48 hours and can often schedule work within 1–2 weeks, weather permitting.
  • Will you fix underlying joist rot?
    • We’ll report any structural issues. Joist repairs are quoted separately and scheduled as needed.
  • Do you use pesticides or herbicides to remove algae/moss?
    • No. We use mechanical removal and biodegradable cleaners; sustainable methods only.
  • What’s the maintenance schedule in this climate?
    • Inspect annually; sand/spot‑repair and reapply a finish every 2–4 years depending on sun exposure.
