Dry Rot Repair in Arlington, WA
Soft trim, rotted siding or a spongy corner? We repair the wood and stop the leak behind it. A soft window sill or a bubbling corner board is usually the last sign of water that has been getting behind the paint for years. We open the area, follow the moisture back to where it came in, remove every piece of decayed wood and rebuild the framing, sheathing, flashing and trim so the wall can shed water again. We serve homeowners across Arlington and nearby Marysville and Lake Stevens.

Why rot repair comes up so often in Arlington
Exposure is what drives rot on Arlington homes. On open lots the windward walls take rain day after day, and water gets behind trim, garage door jambs and the lowest courses of siding. Older downtown houses hide decay under thick paint at sills and corner boards, while Smokey Point subdivision homes tend to rot behind missing kick-outs and poorly flashed windows. We remove damaged wood back to solid material, replace sheathing, framing or trim, and close off the path water took, whether that is a flashing gap, a failed seal or soil piled against the wall.
Arlington blends small-town and rural housing. The historic downtown along Olympic Avenue is ringed by older homes, some from the early 1900s, with wood lap siding, front porches and original trim. Around Smokey Point and Gleneagle, most houses are 1990s–2010s subdivisions with fiber cement, engineered wood or vinyl siding and pressure-treated decks. Beyond the city edges, homes sit on larger lots with detached shops, barns and long decks wrapping the house. Older ramblers and manufactured homes on acreage are common as well, many clad in T1-11 panels and expanded with additions built over the years.
Arlington sits where the North and South Forks of the Stillaguamish come together, and the valley floor around it is wide, open farmland. Storms sweep across with little to stop them, so walls, decks and outbuildings on open lots take hard, wind-driven rain. Winter fog settles into the river bottoms and keeps wood damp for long stretches. Being farther inland, Arlington can also see colder snaps than towns right on the Sound, and freeze-thaw cycles open caulk joints and crack paint, letting water work deeper.
Our crew comes out from our Woodinville office, and we also work in nearby Marysville, Lake Stevens, Stanwood and Mount Vernon.

Recent rot repair projects near Arlington
What we do in Arlington
Columns and porch posts
Posts set on concrete wick water up and rot from the base.
Siding at the corners
Corner boards and the bottom course hold water against the sheathing.
Window sills and trim
Cracked paint at the corners lets water into the end grain, so sills go soft first.
Door thresholds and jambs
Doors without a sill pan leak into the subfloor and jamb.
Roof-to-wall joints
Missing kick-out flashing sends roof water straight into the wall below.
Deck ledgers and rim joists
Where the deck meets the house, poor flashing rots the rim from inside.
Neighborhoods and permits in Arlington
Smokey Point and the plats around it are mostly 2000s construction, so flashing and siding defects lead the list. Gleneagle’s homes near the golf course sit on wooded ground where shade and tree debris keep roofs and decks damp. Older homes near Olympic Avenue downtown need careful trim and porch work. Rural properties on the valley floor toward the river face the most wind and ground moisture, and their outbuildings often need as much attention as the house.
Inside city limits, permits come through the City of Arlington. Small like-for-like fixes, like replacing rotted trim or a section of siding, often don’t need one, but structural repairs, new decks and larger replacements usually do. Many rural homes nearby are in unincorporated Snohomish County instead, so we confirm the right office and its requirements before work begins.

Rot repair in Arlington: cost and timing
Most common causes
Paint and caulk that gave up
Once paint cracks at joints and end grain, wood soaks up rain and stays wet through the winter.
Missing or failed flashing
Roof-to-wall joints, window heads and deck ledgers without proper flashing feed water straight into the wall.
Gutters that overflow
Clogged or undersized gutters dump water onto fascia, trim and the lower wall every storm.
What drives the price in Arlington
The price of rot repair in Arlington depends on how far the damage goes once the wall is open, how much framing has to be replaced, how high the work is and what siding and trim have to be matched. A window sill or a single corner is a short job; rot that has spread behind a whole wall takes more. You get a written price after the free inspection, and we show you photos before any extra work.
Typical timeline
Small rot repairs are usually done within a few days. Bigger jobs with framing, a full wall or several spots around the house tend to run a week or two, with weather and paint cure time setting the pace.
