THE SHORT ANSWER

Kaminskiy Care and Repair repairs loose boards, wobbly railings and soft spots so the deck feels solid again, and most repairs take one visit. In Oregon a deck whose walking surface is more than 30 inches above the ground needs a building permit. We build every repair to pass that inspection. We serve Lake Oswego and the surrounding Oregon communities.

THE FIX MOST DECKS NEED

Lake Oswego Deck and Balcony Repair

Lake Oswego decks hang off hillsides under firs and sit over the lake in the wind, so they are often the most exposed wood on the property: boards soft at the ends, rail posts rotted where they meet the deck, stringers sitting in wet ground, a ledger that has leaked into the wall for years. We replace the boards, sister the joists, reset the posts and railings, rebuild the stairs, flash and bolt the ledger, and sand, stain and seal. A ledger past saving or a balcony that has moved goes to the engineer first, and a new deck is a permitted build.

Wind on top, shade underneath,
and the posts go first

The rail post on the hillside deck rocks at the base and the bolt heads are orange.
The boards nearest the house are dark, and the siding below the deck has a stain.
Moss covers the shaded end and the boards there stay wet into July.
The bottom stair stringer has gone soft where it sits on the ground.
A board on the lake deck cracked along the grain and a second one is cupping.
The finish went gray two summers ago and water no longer beads.

Every one of these is a repair a Kaminskiy-certified technician can scope from our office on Centerpointe Drive, a few minutes from any Lake Oswego street, with the joists and the ledger probed while the boards are up.

THE DECK & BALCONY GUIDE

Know your deck before
you call anyone

Why Lake Oswego decks go soft

Fog and shade under the deck, wind and rain on top. Under the firs a deck stays wet from October to June, moss grows on the shaded boards, needles pack the gaps and the post bases, and the water coming off the roof lands on the ledger. Cedar and fir last decades when they drain and are sealed; they go in a few seasons when they sit wet. Carpenter ants and dampwood termites move into wet wood, and a licensed pest company treats them while we fix the water and rebuild.

The railing test

Grab the top rail and push, out and sideways. Movement means the post connection has failed: a notched post, a bolt that rusted through, or a post gone soft at the deck line. On a hillside deck that railing is the only thing between the deck and the drop. We rebuild the connection with through-bolts and hardware rated for the load, replace the post where the base is gone, and set the baluster spacing to code.

Balconies and the permit line

Oregon has no balcony inspection law; what applies is the Building Department's permit line. An ordinary repair in like materials needs no application, and a deck under thirty inches off grade needs no permit. A hillside deck with a rebuilt frame, a new ledger or a new footprint is a permit, and a balcony or deck that has moved, or a beam that carries a roof, goes to an engineer before we touch it. We tell you which on the call.

Keeping it solid

Clear the gaps and the post bases every fall. Trim the fir limbs that keep the deck in shade. Reseal in late summer every two or three years, before the boards go gray. Lean on every railing each spring and mark anything that flexes. A soft board found early is one visit; a soft beam found late waits for a dry window and an engineer.

LAKE OSWEGO, THE LAKE TO THE HILLS

The Lake Oswego deck,
house by house

Our office is in Lake Oswego, and the crew knows which decks hang over the water, which sit under the firs in the Palisades and which porches are on the Landmark List.
THE LAKE AND OLD TOWN

Old Town, First Addition, Evergreen, Lakewood, Hallinan

Cottages from the 1920s to the 1950s with fir porches, lake decks and steps down to the water, some of them on the city's Landmark List. The porch posts go soft at the base, the deck boards over the water cup and split, and the stairs to the lake rot from the bottom tread up. We rebuild in matching material, keep a landmark repair to identical materials and appearance, and seal the end grain before it goes back on.

THE WEST SIDE

Lake Grove, Westlake, Waluga, Mountain Park

1970s to 1990s houses with association standards and decks between neighbors, built before the moisture rules with ledgers nailed to the rim and no flashing. The boards are tired, the rail posts loosen at the bolts, and a stain on the siding under the deck means the ledger has been leaking. We pull the first boards, flash and bolt the ledger, replace the boards and posts, and match the association's stain.

THE HILLS

Palisades, Forest Highlands, Blue Heron, Skylands

Steep lots under tall firs with decks on tall posts, railings carrying the weather and stairs that drop a story to the yard. Boards rot at the ends, posts at the base, stringers at the bottom, and nearly all of these decks stand more than thirty inches off the ground, so a rebuilt frame is the city's permit. We rebuild what stands, probe the posts and the beam, and name a ledger problem before anyone opens the wall.

WHAT A VISIT LOOKS LIKE

One call, priced
before we come

01Call or text photos

Call 503-912-7872 or text a photo of the worst board, a rail post and the ledger line. Most Lake Oswego deck repairs get a range on the call and a date for the look, often within days with the office a few minutes away.

02The look and the written scope

A technician probes the boards, posts, joists, beam and ledger, measures the height off grade, and writes the scope: what we rebuild, what the city permits, what the engineer has to see, and the price.

03The repair, in a dry window

Frame first, then boards, railings and stairs, then flashing and fasteners. If the beam or the ledger hides more than the look showed, you hear it before we go on.

04Stain, seal and the warranty

Sand, stain and seal go on when the wood is dry enough to take them. The one-year workmanship warranty is on the invoice.

Not ours in Oregon: a new deck or a bigger footprint, which is a permitted build; a ledger or beam past repair, or a balcony that has moved, which an engineer signs off first; deck lights and outlets, which a licensed electrician wires; and treating the carpenter ants or dampwood termites, which a licensed pest company does before we rebuild.
RULES WORTH KNOWING

Licenses, permits and
the Landmark List, in plain words

Who can do the work

Oregon requires a Construction Contractors Board license of anyone paid to repair or improve a home and draws no line between a contractor and a handyman; the one exception is a casual one-off by someone outside the trade who does not advertise. Kaminskiy Care and Repair holds CCB #252813, is bonded and insured, with Kaminskiy-certified technicians. Deck wiring belongs to a licensed electrician and a beam or ledger past repair to an engineer, and both are named on the call.

Permits

Lake Oswego's Building Department administers Oregon's statewide residential code. Under it an ordinary repair with like materials, a board, a railing, a tread, needs no application, and a deck whose walking surface is under thirty inches off the ground needs no permit. Most hillside decks are taller than that, so a rebuilt frame, a new ledger, a replaced beam or a wider deck is the city's alteration-and-repair permit, and we say so on the call rather than find out at the counter.

The Landmark List and the HOAs

About seventy Lake Oswego properties are on the city's Landmark Designation List, many in Old Town and First Addition, and the designation governs the outside of the house, porches and steps included. The city's guide says ordinary maintenance and minor repairs with identical materials and appearance need no application, so a porch board or post replaced in kind is how we work there. Mountain Park, Westlake and the hillside associations rarely need a form for a repair stained to match; a new railing style or stain color sometimes does, and we put it in writing.

Call 503-912-7872

The office is on Centerpointe Drive, so a Lake Oswego deck is usually on the calendar within days. We answer in under three rings, price a board, railing or stair repair from a photo on the call, and finish most of those in one visit. A frame repair gets a look, a written scope and a dry window.

We repair first. New boards, reset posts and railings, rebuilt stairs and a real seal bring most Lake Oswego decks back for far less than a rebuild, as long as the joists, the beam and the ledger are sound. When they are not, we show you the probe marks and say so; a new deck on a hillside lot is a permitted build and often an engineer's drawing, and we tell you what that takes.

A repair in like materials, no. Oregon's residential code asks for no application for an ordinary repair, and a deck under thirty inches off the ground needs no permit at all. A hillside deck with a rebuilt frame, a new ledger, a new beam or a bigger footprint is a Lake Oswego Building Department permit, and we say which yours is on the call.

It depends on how much of the frame the rot reached. Text a photo of the worst board, a post base and the ledger line and you get a range on the call; after the look you get a written scope with the boards, hardware and finish priced before anything is cut. What you approve is what you pay.

Yes. A one-year workmanship warranty in writing on every deck and balcony repair, done by Kaminskiy-certified technicians, from a company that holds CCB #252813 and is bonded and insured.

Yes. The designation governs the exterior, and the city's own guide says ordinary maintenance and minor repairs using identical materials and appearance need no application. A fir porch board, a turned post or a step replaced in kind is exactly that, and we photograph before and after. Changing the material or the look is where the city wants to review, and we tell you when a repair is near that line.

All of Lake Oswego from our Centerpointe Drive office: Old Town, First Addition, Evergreen, Lake Grove, Westlake, Mountain Park, Palisades, Forest Highlands and Blue Heron, plus West Linn, Tualatin and Tigard. Call 503-912-7872 to confirm your address.
