THE SHORT ANSWER

Kaminskiy Care and Repair rebuilds rotted wood on Lake Oswego homes, where the wood is worth matching: the cedar shingles and fir sills on the cottages of Old Town and First Addition, the long runs of trim and the decks under the firs in the Palisades and Forest Highlands, the railings and ledgers on the lake-facing lots, the window corners on the 1980s and 1990s streets of Westlake and Mountain Park. Each piece is cut back to sound wood, rebuilt with the same profile and exposure, primed on all faces, painted or stained to match and the water path fixed. When carpenter ants are in the wet wood, a licensed pest company treats first and we rebuild after. The price is in writing before anything starts. Since 2024 that crew has completed 90 repair visits on 49 Lake Oswego homes.

THE RIGHT WAY TO FIX ROT

Cut Out & Rebuilt in Lake Oswego

Firs that keep a wall in shade from October to June, a lake breeze that never quite dries the siding, cedar shingles that were sound for eighty years until the paint failed: Lake Oswego rot is patient. We cut back to sound wood, match the shingle or the profile, back-prime and seal, and fix the gutter or the grade that fed it.

WARNING SIGNS

What Lake Oswego rot looks like
before it gets expensive

Call 503-912-7872
Cedar shingles on the shaded wall have gone dark, soft and mossy at the butts.
A fir sill on a First Addition cottage crumbles at the corner.
A deck rail post under the firs wobbles at the base.
Fascia behind a gutter full of needles is stained and soft.
Sawdust keeps appearing on the sill below the trim, the sign of carpenter ants.
The buyer's pest and dry rot inspection listed the deck and two windows.

Old cedar and fir deserve a repair that matches them. A Kaminskiy-certified technician prices most Lake Oswego sill, trim and shingle repairs on the call, in writing; a deck, a railing run or a whole elevation gets a look first and a written scope.

THE LAKE OSWEGO ROT & TERMITE GUIDE

Know the enemy before
you call anyone

Why Lake Oswego wood rots

Shade, needles and age. Under the firs a wall stays wet from October to June, moss grows on the shaded shingles and holds the water against the butts, and needles block the gutters so the fascia takes the overflow. The cottages by the lake have cedar and old-growth fir that lasted eighty years because they were painted and drained; once the paint fails or a bed is mulched up to the bottom course, the end grain drinks for nine months a year. We look at the shaded wall and the bottom course first.

The Northwest's wood destroyers

Carpenter ants carve nests in wood that is already wet and leave a sawdust pile below the trim; they do not eat the wood. Pacific dampwood termites nest inside moist, damaged wood and show up where the rot already is. Subterranean termites are rarer here and leave soil tubes on a foundation. Flying dampwood termites in late summer are not an infestation by themselves. A licensed pest company treats the colony; we fix the water and rebuild the wood after.

Matching shingles and old profiles

On a shingled wall we replace only the courses that went soft, weave the new shingles into the old with the same exposure, back-prime and paint or stain to match, so the repair reads as original. On a lap-sided house we match the profile and the reveal; when a profile is no longer milled we say so and show the closest match first. A whole-wall re-side is a different job.

Keep it dry under the firs

Clean the gutters twice between October and May, because the needles do not stop. Limb the trees up so the shaded wall gets light and air, and keep shrubs a foot off the siding. Hose the moss off the shingles in a dry week. Keep soil and bark dust below the bottom course, and repaint or restain the shaded walls on a schedule, not when they peel.

LAKE OSWEGO, LAKE TO HILLS

Where the house sits decides
where the rot starts

Kaminskiy has rebuilt rotted wood on Lake Oswego homes since 2005, from our office in Hillsboro. The lake, the west side and the hills do not rot in the same place.
THE LAKE AND OLD TOWN

Old Town, First Addition, Evergreen, Lakewood, Hallinan

Cottages and houses from the 1920s to the 1950s with cedar shingles, lap siding, fir trim, fir sills and porches, some near the water and the creeks and some on the city's Landmark List. Shingle butts, sill corners, porch posts and the bottom courses go first. We rebuild them in matching material and keep a landmark repair to identical materials and appearance, which is what the city asks.

THE WEST SIDE

Lake Grove, Westlake, Waluga, Mountain Park

Streets from the 1970s to the 1990s with association standards, cedar and hardboard siding and decks between neighbors. Water got behind siding that had no gap to drain, so the rot shows at window corners, the garage jamb and the deck ledger. We rebuild the section, correct the flashing and match the association's color.

THE HILLS

Palisades, Forest Highlands, Blue Heron

Steep lots under tall firs with decks and railings carrying the weather and long runs of fascia under needle-filled gutters. Deck boards rot at the ends, rail posts at the base, the fascia behind the gutter goes dark, and a ledger can hide damage behind the siding. We rebuild boards, rails and fascia where they stand and name a ledger problem before anyone opens the wall.

The same Hillsboro crew covers Lake Oswego and the rest of the metro; the Portland dry rot and wood rot repair page has the Portland rule on permits and historic districts and the Oregon pest and dry rot inspection in plain words.

WHAT A VISIT LOOKS LIKE

One call, a written price,
then the rebuild

01Call, or text a photo

A fascia board, a sill or a trim piece is priced on the call, in writing. A bigger rebuild gets a look first and a written price before anything starts.

02Open it up, find the edge

We cut back to sound wood and probe how far the rot really goes. If it runs further than the photo showed, you hear it before we go further, with the price.

03Rebuild, prime, paint, seal

New wood primed on all sides, caulked, painted to match, and the water path that caused it fixed: the drip edge, the flashing, the gutter end, the sprinkler.

04Clean up, warranty in writing

The work area is cleaned before we leave, and every rot repair carries our one-year workmanship warranty.

Not our lane, and we say so on the call: termite treatment, fumigation and inspection reports (a licensed pest company does those, and we rebuild after them), roof replacement, foundation work and structural engineering. If the rot has reached a beam or a ledger, we tell you what it needs before anyone opens a wall.
RULES WORTH KNOWING

Permits, termite reports and HOAs,
in plain words

Permits

Lake Oswego's Building Department administers Oregon's statewide residential code: no permit to repair or replace siding that is not fire-rated, to replace a window or a door in the same opening, to paint, or for a deck under 30 inches, and no application for an ordinary repair with like materials. A rebuilt sill, a course of shingles or a run of trim is that kind of repair. A deck over 30 inches, a rotted beam or a post that carries a roof is where the city's alteration-and-repair permit starts, and we tell you on the call.

The pest and dry rot inspection

Oregon has no mandatory termite report on a sale; a Lake Oswego buyer orders a pest and dry rot inspection from a licensed inspector, alone or inside the whole-home inspection, and it lists what it found: soft sills, rotted shingle butts, deck boards, ant damage. We do the carpentry on that list, priced from the report in writing, and the inspector rechecks before closing.

The Landmark List and the HOAs

About seventy Lake Oswego properties are on the city's Landmark Designation List, many of them in Old Town and First Addition. The city's own guide says ordinary maintenance and minor repairs using identical materials and appearance need no application, and painting a painted surface needs no approval; replacing historic windows or changing materials does, and we tell you when a repair is near that line. Mountain Park, Westlake and the hillside associations rarely need a form for a repair painted to match.

GOOD QUESTIONS

Call 503-912-7872

A sill, a trim piece or a course of shingles is priced on the call and usually scheduled within days; the painting waits for a dry stretch. A deck, a railing run or a whole elevation is sized after a look, with the scope in writing before anything starts.

Yes, after a licensed pest company has treated. We cut out the carved trim, shingles and the framing we can reach, fix the leak or the shade problem that kept the wood wet, and rebuild. The treatment is the pest company's; the rebuild is ours.

Yes, and the city asks for exactly what we do: identical materials and appearance. Shingles, siding, sills, trim and porch posts are carpentry, and Kaminskiy is licensed, bonded and insured, so a splice into a stringer or a rim joist is fine too. A beam or a ledger gets named before anyone opens a wall.

The run of wood that has to come out, the height and the access on a hillside lot, and the shingle or profile it has to match. A sill corner and a deck under the firs are not the same visit. Text a photo and the price is in writing before anything is scheduled.

Yes. We replace only the courses that went soft, weave the new shingles into the old at the same exposure, back-prime and paint or stain to match. New cedar weathers in within a season, or we stain it to match on the day.

Not for a course of shingles, a sill, a same-size window or door, painting or a low deck: the state code Lake Oswego administers exempts those, and an ordinary repair needs no application. A deck over 30 inches, a rotted beam or a load-bearing post is where a permit starts, and we tell you on the call.

All of Lake Oswego from our Hillsboro office, including Old Town, First Addition, Lake Grove, Westlake, Mountain Park, the Palisades and Forest Highlands, plus West Linn, Tigard, Tualatin and Portland's southwest. Call 503-912-7872 to confirm your address.
