Bay Area Water Damage Repair

The Peninsula gets its water from November to March, and the houses take it differently. The 1920s streets of San Mateo Park and Professorville have wood floors over crawl spaces that flood and subfloors that soak from below; the Eichlers south of Oregon Expressway have flat roofs with scuppers and copper radiant lines in the slab; Foster City and Redwood Shores sit on fill with the bay a few feet down. We trace the source, have the licensed plumber or roofer stop it, cut out the wet drywall, insulation and trim, dry the cavity and rebuild to match.

THE WATER DAMAGE GUIDE

Know what water does
before you paint over it

Why the stain comes back

Because the water keeps coming. On the Peninsula that is a scupper that drains slowly, a crawl space that fills every wet winter, a galvanized line that drips inside a wall, a radiant loop with a pinhole, or a fog-side wall that never dries between storms. Paint over the ring bleeds through in weeks. We trace the source, have the right licensed trade stop it, and run drying equipment until the meter says the cavity and the subfloor are dry.

Repair, or replace?

Plaster that is stained but hard on the lath can be dried, sealed and skimmed; plaster that is soft or loose comes out to sound edges. Drywall that stayed wet, swelled at the joints or sagged comes out with the insulation behind it. A subfloor over a flooded crawl space is the Peninsula's particular question: boards that cupped and dry flat stay, delaminated plywood is replaced, and a joist the water softened goes to the engineer before anything goes back. We probe and meter at the look and the written scope says which.

When it is a remediation company's job

California issues no license for mold remediation, so there is no licensed remediation company to look up on a state list; the state's guidance is to remove visible growth and fix the moisture. A small surface spot on drywall, trim or grout we remove with the material and treat. Growth across a wall, inside a cavity, under a floor over a wet crawl space, or anywhere someone in the house has breathing trouble calls for a remediation company with industry certification and containment, and the air or surface testing is theirs. We say so at the look and rebuild after their clearance.

Keeping it dry

Clear the scuppers and the roof drains before November, grade the yard away from the crawl-space vents and keep the vents open, and put a sump in a crawl space that floods. Swap rubber washer hoses for braided steel, put a pan under the water heater, and have the licensed plumber replace the last galvanized run. Watch the bill in a radiant house. Most of what we rebuild on the Peninsula was a winter of slow water nobody saw.

THE PENINSULA, FOG SIDE TO BAYSIDE

The Bay Area water story,
house by house

Our Peninsula office is on Twin Dolphin Drive in Redwood Shores. A pre-war house over a crawl space, an Eichler on a slab and a townhome on the bayside fill get wet from different directions.
THE PRE-WAR STREETS

San Mateo Park, Baywood, Aragon, downtown Redwood City, Mount Carmel, Professorville and Old Palo Alto, central Menlo Park

Houses from the 1900s to the 1940s on raised foundations with wood floors over a crawl space, lath and plaster walls, galvanized supply lines in some and cast iron drains in most. The water comes from below as often as above: a crawl space that floods in a wet winter wicks into the joists and the subfloor, a galvanized line drips inside a wall, a pan under original tile gives out. We cut plaster to sound lath or drywall to sound edges, dry the cavity and the crawl space with equipment, replace what the water softened, and rebuild to the original surface. A pre-1980 house gets a sample of plaster or joint compound tested before we cut, since asbestos was common in both.

THE BAYSIDE AND THE FILL

Foster City, Redwood Shores, Shoreview, the east side of San Mateo and Redwood City

Ranches, townhomes and condos from the 1960s to the 1980s on engineered fill behind levees and lagoons, with the water table a few feet down and the ground settling a little every year. Slab edges stay damp, drywall at the base of a wall swells, and in the townhome and condo communities the leak is often the unit above, a washer hose or a stack in the wall. We take out what is wet, dry both sides, rebuild and paint, and write the scope so the association and the insurers can read who owns which wall.

THE MID-CENTURY TRACTS AND THE HILLS

Palo Alto south of Oregon Expressway, Greenmeadow and Fairmeadow, San Carlos, Sharon Heights, the Redwood City and San Mateo hills

Eichlers and the ranch tracts of the 1950s and 1960s, with flat or low-slope roofs drained by scuppers, floor-to-ceiling glass, and copper radiant heat lines cast in the slab. A clogged scupper puts a storm on the ceiling; a radiant line that pinholes warms one spot on the floor and the baseboard swells. We open the ceiling or the wall, dry it, and rebuild to the Eichler lines, with the licensed plumber handling the radiant loop and the licensed roofer the scupper, and we never drill a radiant slab blind.

WHAT A VISIT LOOKS LIKE

One call, priced
before we come

01Call or text photos

Call 855-695-1195 or text a photo of the stain, the cupped floor or the swollen baseboard. Most repairs get a range on the call and a date for the look, and the office is off Highway 101 between San Mateo and Palo Alto.

02The look, the meter and the written scope

A technician traces the water with a moisture meter, checks the drywall, the framing, the subfloor and the crawl space, and writes the scope: what comes out, how long the drying runs, which licensed trade stops the source, what is rebuilt, and the price.

03Stop it, dry it, rebuild it

The licensed plumber or roofer we schedule stops the source. We cut out the wet plaster, drywall, insulation and trim, set the drying equipment, treat the framing, then patch or hang, texture and paint, usually in a few visits across a week or so.

04Clean up, documents, warranty

Photos of the open wall and the meter log go in your file for the insurer or the association. The dust leaves with us, and the one-year workmanship warranty is on the invoice.

Not our lane in California: mold remediation past a small surface patch and any air or surface testing, which go to a remediation company with industry certification; the leak itself, which the licensed plumber or the licensed roofer we schedule stops; and any joist, beam or post the water softened, which an engineer calls before we rebuild.
RULES WORTH KNOWING

Licenses, six permit desks
and the insurer, in plain words

Who can do the work

California lets an unlicensed person take a job only when the whole price is under one thousand dollars, the work needs no permit, nobody is employed to help and nothing about the business says contractor; a water damage rebuild clears that line with the first sheet of drywall. Kaminskiy Care and Repair is a licensed California contractor (License #1120648), bonded and insured, with Kaminskiy-certified, background-checked technicians, and every job over the state's written-contract threshold goes on paper first. The leak is a licensed trade's: a supply line, a radiant loop or a shower valve to the licensed plumber, a scupper or a roof to the licensed roofer, and we schedule them.

Permits for drywall and subfloor

Every Peninsula city publishes its own sheet, and they agree on the basics: painting and finish work need no permit, and an ordinary repair to a structure needs no application under the state code, which covers a patched ceiling or a wall rebuilt like for like. They part ways past that. San Mateo says a permit is required for any repair not on its exempt list and issues siding and stucco repair permits over the counter; San Carlos says most anything requires one; and Palo Alto, Foster City and San Carlos ask for a permit on a replacement window when a window leak is the cause. A subfloor, a joist or any framing the water softened is a permit in all six, and we ask the city before the quote rather than guess. The plumber's and the roofer's work carries its own.

Insurance, the HOA and the condo

A burst line, a failed water heater or a storm through a sound roof is the sudden loss most policies cover; ground water into a crawl space and a leak that ran for months usually are not, and the policy and the adjuster decide. We photograph the open wall, log the meter readings and write a scope your adjuster can read; we do not negotiate claims, which a public adjuster licensed by the Department of Insurance does. In the Foster City and Redwood Shores townhome and condo communities California's common-interest law makes the association responsible for the common area and you for your unit unless the CC&Rs say otherwise, so whose wall the leak lives in is settled with the manager before the scope is final.

No, that is a remediation company's trade. We cut out and replace the plaster, drywall, trim, insulation and cabinet panels the water ruined, treat the framing, and a small surface spot comes out with the material. Growth across a wall, inside a cavity, under a floor or in the ducts, and any air or surface testing, belong to a remediation company with industry certification; California licenses none, so we tell you who we trust and rebuild after their clearance.

Nearly always. On the Peninsula the usual suspects are a scupper or roof drain, a crawl space that flooded, a galvanized supply line, a radiant loop in an Eichler slab, a shower pan under old tile, a washer hose, and in a townhome the unit above. We trace the path with a moisture meter before anything is closed, and the licensed plumber or roofer confirms and fixes it; a rebuild over a live leak is money spent twice.

Yes. In the pre-war houses that means plaster, cut to sound lath, patched with plaster or a drywall inlay and skimmed flush. In an Eichler it means keeping the flat ceiling and the clean lines the city's guidelines expect. In drywall it means matching the texture across the patch, a stain-blocking primer and paint to the corner. A pre-1980 surface gets a sample tested before we sand or cut it.

It depends on how far the water ran and how long it sat. Text a photo and you get a range on the call; after the look you get a written scope with the tear-out, the drying, the rebuild and the licensed trade priced before anything starts. The price you approve is the price at the house, and the scope is written so your insurer can read it.

Often, when the cause was sudden: a burst line, a failed water heater, a storm through a sound roof. Ground water into a crawl space, slow leaks, seepage and deferred maintenance usually are not covered, and the policy and the adjuster decide. We give you photos of the open wall, meter readings and a line-item scope; we do not adjust claims, and a public adjuster licensed by the state does if you want one.

Not always. We meter the joists and the subfloor from below and the finish floor from above. Boards that cupped and dry flat with the crawl space dried out and vented stay; plywood that delaminated and any joist that stays soft are replaced, and a joist that carries the floor goes to the engineer first. The drainage fix, a sump or a regrade, is named in the scope so it does not happen next winter.

Yes, around the plumber's work. The licensed plumber we schedule finds the loop and either repairs it in the slab or runs a new line overhead; we open what the plumber needs and never drill the slab blind. Then we dry the slab edge and the wall, rebuild the drywall and the baseboard to the Eichler lines, and put both pieces on one scope.

San Mateo, Foster City, Belmont, San Carlos, Redwood City and Redwood Shores, Menlo Park, Atherton and Palo Alto, plus Burlingame, Hillsborough, Woodside and East Palo Alto. The East Bay and the South Bay have their own Kaminskiy offices. Call 855-695-1195 to confirm your address.
