Homes in Seattle
Most of the Seattle homes we work on are north of the Ship Canal. Ballard, Wallingford, Greenwood and Ravenna are full of Craftsman bungalows and foursquares from the early 1900s, along with brick-and-stucco Tudors from the 1920s and 30s. Many still wear their original old-growth cedar lap siding or shingles, nailed straight to board sheathing with no house wrap behind. Farther north, Lake City, Northgate and Maple Leaf filled in after the war with ramblers and daylight basements. Narrow city lots, alleys and tight side yards are the norm, and newer three-story townhomes with rooftop decks and mixed siding have replaced many older houses near the commercial streets.
Seattle’s winters are long, gray and drizzly rather than stormy, so exterior wood rarely gets a full drying day from October into spring. On homes near the water, wind off Puget Sound or Lake Washington pushes rain sideways into the exposed walls. Tight lot spacing works against drying too, because a wall that faces a neighbor five feet away almost never sees direct sun. The result is slow, steady decay at window sills, siding butt ends, deck ledgers and porch floors rather than one dramatic failure.
Conditions change block to block. Magnolia and the Ballard bluffs take open wind off the Sound, so west and south walls weather fastest. Laurelhurst and View Ridge face Lake Washington with similar lake-driven rain. Ravenna and the Thornton Creek corridor through Lake City sit under big trees in damp ravines, where moss and shade keep siding wet. Phinney Ridge and Queen Anne get more sun but more wind, while dense Fremont and Wallingford blocks shade each other.

Learn moreWhat we fix most in Seattle homes
Chimney Chase Repair
Rotted wood-framed chimney chases rebuilt, sided and flashed so they stay dry. In Seattle, that usually means wood-framed chimney chases take water at the top and rot from the inside.
Deck Repair & New Decks
Repairs, rebuilds and new composite decks, built on solid framing with the flashing done right. In Seattle, that usually means decks start to rot from the framing and ledger up, long before the boards look bad.
Deck Waterproofing & Flashing
Walkable waterproof coatings, slope fixes and flashing that keep water out of your walls and ceilings. In Seattle, that usually means worn coatings and missing flashing let water into walls and ceilings.
Every visit starts with a free inspection: we probe the wood, check moisture, photograph what we find and give you a written price before any work starts. Small like-for-like repairs often don’t need a permit, but structural work, new decks, and larger siding or window replacements usually do. The City of Seattle handles permits through its Department of Construction and Inspections, and homes in historic districts may need extra review. We check with the City of Seattle before starting and tell you up front if a permit is part of the job.

A year-round checklist for Seattle homes
Fall
- Clean gutters and downspouts before the first big storms
- Check deck boards, railings and stairs before they get slick
- Look over window sills and trim for cracked paint
Winter
- Watch for stains on ceilings under decks and balconies
- Note any spots where water pools against the house
- Check that downspouts drain away from the foundation
Spring
- Walk the house and press trim, sills and corners for soft spots
- Wash moss off siding, decks and roofs gently
- Book repairs early: summer schedules fill fast
Summer
- Repaint and recaulk while the wood is dry
- Reseal wood decks and recoat balcony surfaces
- Replace rotted wood before the rain comes back
Seattle gets the same long wet season as the rest of the region, so most exterior damage builds slowly from October to May. A short walk around the house each season catches problems while they are still small.
