THE SHORT ANSWER

Kaminskiy Care and Repair patches and finishes drywall in Foster City homes, where every house and every condo stands on sand fill pumped over bay mud in the 1960s and the ground has been settling gently ever since. The diagonal crack from the corner of a slider on Treasure Isle, the nail pops marching along a ceiling seam in a 1970s house by Boothbay Park, the stain on a Sea Colony ceiling after the washer upstairs overflowed, the crack above the garage door opening in a Whalers Island townhome, the knob hole in a rental near Foster Square and the forty anchor holes after the lease: each gets sound board, taped seams, three coats sanded flat, the texture matched and primer. Water waits for the source to be fixed and the board to dry. The price is in writing on the call and most patches are finished in one visit.

THE FIX MOST WALLS NEED

Patched & Texture Matched in Foster City

Foster City was engineered before it was built, and the drywall tells the story: the sand fill over the old marsh settles unevenly, so the house moves a hair each year and the wall shows it at the cut corners of doors and windows. A 1970s lagoon-front house carries orange peel and fifty years of patches; the townhomes and condos that make up much of the city carry smooth and light-textured walls and a neighbor on the other side of them. We tape the settling crack so it stays closed, match the finish, and write the scope the association can read.

THE FOSTER CITY DRYWALL GUIDE

Know your walls before
you call anyone

Why Foster City walls crack

The city sits on sand fill dredged from the Bay and pumped over Brewer Island's marsh in the 1960s, with bay mud under it, and fill over mud settles unevenly for decades. So the house moves a little, year after year, and the drywall cracks where the sheets were cut: the corners of doors, windows and sliders, the seam above the garage opening, the ceiling line of a two-story entry. Those cracks are taped with paper or mesh, filled, feathered wide and textured so they stay closed; caulk alone opens again by the next dry September. A crack that steps across the wall or widens every year is a question for the foundation, and we say so instead of patching it twice.

Orange peel in the houses, smooth in the condos

The single-family neighborhoods from the first decade, around Boothbay Park, Sea Cloud Park and the lagoon fingers, carry a medium orange peel on half-inch board and a sprayed ceiling that is tested by a licensed lab before anyone sands it if it dates from before 1980. The townhomes and condos of Sea Colony, Whalers Island and Foster Square run smoother: a light orange peel, a skip trowel or a true smooth finish that shows every edge of a careless patch. Each is matched on a test board against your wall, and a smooth wall gets the wider feather and the raking-light check before primer.

Water from the unit above

Much of Foster City is attached housing, and in an attached building the water comes from above or next door: a washer hose, a tub overflow, a shower pan, a water heater in the closet upstairs. The ceiling below shows a ring weeks later. The plumber or the association fixes the source, the ceiling dries and reads dry on the meter, then we cut out the stained section and replace it, textured and primed. Dark growth bigger than a dinner plate is a licensed mold remediation company's job first, and we tell you so on the call.

Patch, paper patch, poster patch, full sheet

A hole smaller than your hand gets a backed patch; bigger than your hand and smaller than a laptop, a paper patch; poster-sized, a framed backer and a new section; a soaked or crushed area, or anything up to a full sheet, new board screwed to the studs with every seam taped. Three coats, sanding, the matched texture and primer are the same on all four. A settling crack is a fifth kind: taped, not just filled, because a filled crack in Foster City reopens.

FOSTER CITY, LAGOON TO LEVEE

Where the house sits decides
what the walls do

Kaminskiy has patched and finished walls in Foster City homes since 2005. The first lagoon-front streets, the townhome villages and the newer condos crack in different places.
THE FIRST NEIGHBORHOODS

the streets around Boothbay Park, Sea Cloud Park, Edgewater Park and Marlin Park, Treasure Isle

Single-family houses from the mid 1960s and 1970s on the first fill, orange peel inside, sprayed ceilings from before 1980 tested by a licensed lab before anyone touches them, and settling cracks at the door and slider corners that reopen after every dry summer. Nail pops along the ceiling seams, corner bead rounded by fifty years, and the water heater closet that soaks a wall from the bottom.

THE TOWNHOME VILLAGES

Sea Colony, Whalers Island, Isle Cove, Bayporte, Schooner Bay

Attached homes from the 1970s through the 1990s with a shared wall, a shared roof and a neighbor's plumbing over your ceiling. Light orange peel and skip trowel to match, the crack above the garage opening, and the leak that started two doors down. We repair the drywall on your side, match the finish, and write the scope as its own line for the association and the adjuster.

THE NEWER CONDOS AND RENTALS

Foster Square, Marina Point, the Metro Center and Vintage Park apartments, the lagoon-front condos

Smooth and level walls from the 2000s on, tall entries over eight feet priced after a look, new-building settling hairlines at the window corners, and rental turnovers every spring with anchor holes by the room. The finish standard is the builder's, so the repair gets the wider feather and the raking-light check, and the HOA color goes on over the primer.

Foster City is one of ten Peninsula and South Bay cities on a crew that works the whole Bay; the Bay Area drywall repair page puts the fill, the fog and the sun side by side, with each city's permit desk and the water-damage paperwork explained.

WHAT A VISIT LOOKS LIKE

One call, a written price,
then the patch

01Call, or text a photo

Hold your hand over the damage and tell us: smaller than your hand, bigger than your hand, poster-sized, or a whole sheet. We price it on the call, in writing, in under ten minutes.

02The leak first

Water damage is repaired after the source is fixed. If the stain is still wet we tell you who fixes the leak, and we schedule the drywall for when it is dry.

03Patch, tape, three coats, texture

Backing where it needs it, new board cut to fit, every seam taped, three coats of compound sanded smooth, your texture matched, then primer.

04Clean up, warranty in writing

Dust contained and the room left clean. Most patches are finished in one visit; a full sheet may need a short second visit for the final coat, scheduled before we leave.

Not our lane, and we say so on the call: fixing the leak itself (a plumber or roofer does that, and we come after), mold remediation beyond a small dry spot, asbestos or lead testing and removal (a licensed abatement contractor tests an older ceiling or wall first), and framing or structural work. Painting the finished wall is its own page and its own crew.
RULES WORTH KNOWING

Permits, leaks and the paperwork,
in plain words

Permits

Foster City's residential permit sheet follows the California Residential Code: a permit when you construct, alter or repair a structure, and none for painting, papering, tiling, carpeting, cabinets, counter tops and similar finish work; the city's older handout named minor repairs to existing interior drywall or plaster outright, except where the wall is part of a fire-resistive assembly. A patch, a replaced sheet in an existing wall or a ceiling repair is that. A new opening, a removed wall or any framing is a permit, and the fire wall to an attached garage is the exception we watch for.

The leak, the adjuster and the order of work

A washer hose that lets go is the kind of sudden and accidental water damage the state's insurance department lists as typically covered; the seepage that stained a ceiling over months is on its generally-not-covered list. Photograph the ceiling and the source on the day you find them, keep the plumber's invoice, tell the association in writing if the water came from another unit, and we write the drywall scope as its own line. The source is fixed, the board dries and meters dry, then we replace it; never the other way round.

The association, the unit above and the garage wall

Most of Foster City is an association community, and in an attached building the leak upstairs and the ceiling downstairs belong to different owners. California Civil Code 4775 puts the common area on the association and the unit on the owner unless the CC&Rs say otherwise; we repair your side and leave the question of who pays to the documents. The wall and ceiling between a townhome and its attached garage are fire separation under the state code, half-inch board on the garage side and five-eighths Type X under a living space, and a full-sheet repair there goes back with the same board.

GOOD QUESTIONS

Call 650-744-0320

Usually within days from our South Bay crew. The price is in writing on the call, and most patches are finished in one visit; a full sheet or a ceiling section may need a short second visit for the final coat, scheduled before we leave.

Because the house stands on fill over bay mud, and the fill settles a little every year, so the sheet cracks where it was cut around the opening. Caulk or spackle alone reopens the next dry season; taped, filled, feathered wide and textured, the crack stays closed. If it steps across the wall or widens every year we tell you to have the foundation looked at rather than patch it again.

We repair the drywall on your side once the source is fixed and the ceiling reads dry. Who pays is settled by the CC&Rs and the policies, with California Civil Code 4775 as the default; we write the scope on its own line so the association and the adjusters can read it.

Yes. The first neighborhoods carry a medium orange peel, the townhome villages a lighter peel or a skip trowel, and the newer condos run smooth. Each is tested on a scrap board against your wall before the repair is textured and feathered out so there is no edge.

Yes, and it is the most common call we get from Foster City rentals. One hole, one crack, one dented corner is a quick visit, and a room with up to fifteen nail and anchor holes is a menu item of its own.

Size against your hand, then water, texture and height: hand-sized, poster-sized or a whole sheet; dry or water-damaged; orange peel, skip trowel or smooth; eight feet or a two-story entry. Tell us those four things on the call and the written price comes back in under ten minutes.

No. Interior drywall needs no approval. A shared wall, a shared ceiling or water from another unit is a question for the CC&Rs and the association's insurance, and we write the scope so they can read it.

All of Foster City, Treasure Isle, Sea Colony, Whalers Island, Isle Cove, Bayporte, Marina Point and Foster Square, plus San Mateo, Redwood Shores, Belmont, San Carlos and Redwood City. Call 650-744-0320 to confirm your address.
