A live person answers, every time, and we’ll give you a written price before any equipment comes off the truck.
Los Altos homes present a specific set of challenges: original redwood siding that traps moisture, galvanized supply lines that corrode from the inside, and plaster walls that hide leaks for weeks before anyone notices. Our Water Damage Restoration team carries moisture mapping equipment, Injectidry panels, and Dri-Eaz air movers calibrated for mid-century construction. We know what’s behind these walls before we open them.
Why Wendell Restoration San Jose Is Los Altos’s Preferred Water Damage Restoration Company
We’re part of the Relay Home Co. family, founded in 2006, and our Los Altos work follows The Relay Standard: book in a tap, live arrival time, photo updates by text, price in writing before anything starts, and a text invoice you can pay from a link. The number on the screen is the number you pay.
Every technician who arrives at your Los Altos home is background-checked and uniformed, and you’ll see their name and photo before they pull up. We don’t do vague four-hour windows. You get a live arrival time you can track from your phone, like a rideshare. That matters when you’re watching water climb the baseboards in a 1963 ranch on Alicia Way.
Our techs have worked in every Los Altos neighborhood from North Los Altos to the Country Club area. They know the difference between a 1950s shake roof on a rancher off Foothill Expressway and the newer construction near downtown. That local knowledge means faster diagnosis and fewer unnecessary cuts into your walls.
Restoration work we handle
Flooded Basement in Los Altos
A flooded basement in Los Altos typically costs $4,500 – $14,000 to restore, depending on water category, how long it sat, and whether finished walls or carpet need removal. The first sentence of this section tells you what most companies won’t: the price range. We give the same in writing before any work begins.
Los Altos basements divide into two types. Homes built before 1970 on the flats near Permanente Creek often have partial basements or crawlspace-adjacent storage that flood when the creek overflows or when groundwater rises after heavy winter rain. The low-lying streets near Miramonte Avenue and the areas east of Foothill Expressway see the worst of it.
Slab-Foundation Basements
Some mid-century Los Altos homes built on slab foundations have what we call “garden-level” rooms: partially below grade, with original concrete that wicks moisture upward. Standing water here is usually Category 2 or 3, which means extraction first, then antimicrobial treatment before any drying or rebuild.
Crawlspace Water and Vapor Barriers
When a crawlspace floods in Los Altos, proper restoration means removing standing water, then laying a new vapor barrier and checking the subfloor moisture content with a psychrometric reading. Surface-dry is not dry. We track the air’s moisture level so we know when your home is truly dry, not just looks dry.
Water Extraction in Los Altos
Water extraction in Los Altos averages $1,800 – $5,200 for a single room and $5,000 – $12,000 when water has spread across multiple rooms or soaked into original plaster walls. We arrive with truck-mounted extraction units and high-efficiency submersible pumps that pull water fast, then we map the moisture with thermal imaging and pin meters.
Here’s what matters in Los Altos specifically: water hides. Original redwood siding acts like a sponge. Galvanized supply lines leak behind plaster for weeks. You can have a pinhole leak in a Loyola Corners wall that never shows a puddle, just a slowly darkening patch of plaster and a musty smell. Our Water Damage Restoration in Los Altos team knows to check baseplate moisture readings, not just the visible surface.
Containment Before Extraction
In older Los Altos homes, we often set containment before extraction starts. Why? Because the air movement from drying equipment can disturb lead paint dust or asbestos fibers in 1950s plaster. We’d rather control that from the first minute than create a bigger problem.
What Gets Extracted vs. What Gets Cut
Extraction handles water you can see and water we can map in soaked drywall or carpet. Selective demolition handles what extraction can’t: water trapped in wall cavities behind original plaster, soaked insulation, and baseplates that read above 19% moisture. We don’t cut blindly. We cut where the moisture meter says to cut, and we show you the readings first.
Trusted Brands We Service in Los Altos
We run Dri-Eaz air movers and dehumidifiers, Phoenix extractors, XPOWER axial fans, B-Air dryers, and Injectidry panel systems for hard-to-reach cavities like plaster walls and redwood siding. These are the brands used on commercial loss sites, the ones that hold up over a four-day dry-out in a 1968 ranch off Springer Road. We stock local replacement parts and filters in our Bay Area warehouse, so if a dehumidifier needs a swap mid-job, we’re not waiting on a shipment from out of state.
Common Water Damage Restoration Problems We See in Los Altos Homes
- Hidden galvanized pipe pinhole leaks: Original supply lines from the 1950s-1970s corrode from the inside out. Water weeps behind plaster for weeks before you see anything. By the time homeowners call, baseplates are soaked and drywall is wicking moisture upward.
- Moisture trapped behind original redwood siding: Redwood looks solid but absorbs water like a wick. Surface drying leaves moisture behind the siding where mold can grow for months. We use Injectidry panels and cavity drying to pull moisture from behind siding without removing it unnecessarily.
- Asbestos and lead paint in original construction: Cutting into 1950s-1970s plaster or drywall without testing first can release hazardous dust. California regulations require specialized handling. We coordinate asbestos testing before any selective demolition on materials that might contain it.
- Permanente Creek overflow flooding: After heavy winter rain, low-lying streets near the creek see contaminated groundwater pushing into crawlspaces and garden-level rooms. That’s Category 3 water, which requires full antimicrobial treatment, not just drying.

FAQs About Water Damage Restoration in Los Altos
Yes. Redwood siding absorbs moisture deep into the wood fibers, which means surface drying won’t reach the water trapped behind the siding. We use Injectidry panel systems to pull moisture from behind the siding without removing it, and we monitor with psychrometric readings until the air inside the cavity reaches the same moisture level as the rest of the room. Newer stucco or fiber-cement homes dry faster and don’t require this step. Call (669) 200-0453 and ask for a cavity-dry assessment before you sign any contract.
Yes, but the approach is different from a traditional basement. Garden-level rooms on slab foundations often have concrete that wicks moisture upward, so we focus on extraction first, then check subfloor moisture with pin meters. If the concrete is saturated, we run dehumidifiers and air movers directed at the slab surface, and we typically install a vapor barrier in the crawlspace or under the slab edge if we find hydrostatic pressure. Call (669) 200-0453 for a free inspection with moisture readings.
We pause any selective demolition and coordinate asbestos testing before cutting into materials that might contain it. California regulations require specialized handling, and our crews are trained to set containment before disturbing 1950s-1970s plaster. Wet asbestos-containing plaster still poses a dust risk when it dries and is cut, so we take the same precautions regardless of moisture level. If testing confirms asbestos, we work with a licensed abatement contractor before restoration continues.
Permanente Creek overflow water is Category 3: it contains sewage, agricultural runoff, and ground contaminants. Category 3 water in a Los Altos crawlspace requires extraction, removal of porous materials like insulation, full antimicrobial treatment on framing, and a new vapor barrier before drying begins. We don’t classify it as Category 1 to save time or money. That’s a known failure mode in this trade, and it leaves contaminated drywall and framing in a wall cavity that will cause problems for years.
Galvanized steel supply lines corrode from the inside out. The zinc coating wears thin, rust forms, and pinholes develop that weep water slowly behind original plaster walls. The plaster absorbs the water and wicks it upward through the baseplate. You might not see a puddle for weeks. Last winter we responded to a 1960s ranch on Miramonte Avenue in Loyola Corners where a pinhole leak had been weeping behind original redwood paneling for weeks. Our techs set containment, pulled moisture readings that climbed past 19% on the baseplate, and ran Injectidry panels with Dri-Eaz air movers for four days before we cut out the affected drywall, treated the framing with antimicrobial, and restored the wall to pre-loss condition. If you smell mustiness or see a slow-growing stain, call (669) 200-0453. We’ll map the moisture and find the leak.
