Kenmore homes

Why structural repair comes up so often in Kenmore

Kenmore split-levels and hillside homes often have lower framing close to wet soil, and years of leaks around sliders, decks and gutters can soften sill plates and rim joists. We also find rotted posts and beams under decks and porches. A floor that feels soft near a door, or a wall with cracking drywall inside, can point to hidden rot. We support the structure, replace damaged framing with treated lumber, and correct the moisture issue so the repair lasts in Kenmore’s wet climate.

Kenmore wraps around the north tip of Lake Washington where the Sammamish River flows in. Most of its homes were built from the 1960s through the 1980s: split-levels, ramblers and two-story houses on wooded slopes in Inglewood, Arrowhead, Moorlands and Uplake, with lakefront and view homes along the Juanita Drive side. Cedar lap, hardboard and T1-11 siding are common, and many homes have large decks facing the lake or the woods. Newer townhomes and apartments have gone up near downtown Kenmore and along Bothell Way, mixing modern construction into an older housing stock.

Kenmore gets weather from two directions. Homes near the lake catch wind-driven rain and fog rolling off Lake Washington, which hits lakeside walls and decks hard. Up the hills, tall evergreens keep siding and decks shaded, and moss grows quickly on north-facing surfaces. The Sammamish River valley at the city’s low end holds morning fog and damp air. Steady winter rain on wooded slopes means many Kenmore homes stay wet on at least one side from fall through spring.

Our crew comes out from our Woodinville office, and we also work in nearby Bothell, Lake Forest Park, Kirkland and Woodinville.

Local know-how

Neighborhoods and permits in Kenmore

Homes along Juanita Drive and the lakefront take wind and spray off Lake Washington, so view decks and lakeside walls wear quickly. Inglewood and Arrowhead are hilly and heavily treed, with shade and moss on north walls and decks. Moorlands and Uplake are steep in places, sending runoff toward the uphill side of houses. Neighborhoods near Saint Edward State Park have mature forest close to the homes, while downtown has newer, denser construction.

Small like-for-like repairs usually don’t require a permit, while structural work, new decks and larger replacements usually do. The City of Kenmore handles residential permits, and lakefront or steep-slope lots can involve extra review. We check with the City of Kenmore before starting and keep you informed about what the job needs.

Guide

Structural repair in Kenmore: cost and timing

Most common causes

Long-term leaks

Years of small leaks at decks, doors and walls slowly rot posts, beams and sill plates.

Undersized or failed connections

Old nails and missing hangers let members shift, crack and take on water.

Rot spreading from siding or decks

Damage that starts in siding or a deck ledger can reach the framing behind it.

What drives the price in Kenmore

Structural repair in Kenmore is priced by how much framing has to be replaced, how much shoring is needed, access, and whether a permit or engineer is required. A single post or short section of sill plate is a smaller job than rebuilding framing under a deck or wall. You get a written price after the free inspection.

Typical timeline

Most post, beam and sill repairs take a few days. Larger framing rebuilds take one to two weeks, plus permit time if one is required.

Backed by a 24-month workmanship warranty

FAQ

Questions Kenmore homeowners ask about structural repair

Can you fix a lake-view deck in Kenmore?
Yes. Lake-view decks in Kenmore take wind and rain off Lake Washington, which wears out boards, railings and fasteners. We inspect footings, framing and the ledger connection, repair what is failing, and rebuild with materials and hardware that hold up to the exposure. If the deck is beyond repair we can design and build a new one.
Do structural repairs in Kenmore need a permit?
Some do. We tell you if your repair needs a permit or engineer and help with the process.
Is my house safe if a post or beam is rotted?
It depends on the load and how far the rot has gone. We check it and add temporary support right away if needed.
How long do structural repairs take?
Most post, beam and sill repairs take a few days. Larger rebuilds take longer and we give you a schedule up front.
Can you work while we live in the house?
Yes. Most structural repairs we do are on the exterior, under decks or porches, and the house stays usable.
