Fast, Reliable Mold Remediation Across Kensington
Mold remediation in Kensington, CA typically costs between $1,800 and $6,500 depending on how far the growth has spread and whether the crawl space or attic is involved. We get calls from Kensington homeowners every week, and we know exactly what we’re walking into: hillside homes built before 1950, steep lots, and crawl spaces so tight you can barely fit a flashlight in there. If you’ve spotted mold or you smell that musty odor that won’t go away, call (855) 915-0646. Wade Ferris answers his own phone, and he’ll tell you straight whether you need full remediation or just a targeted treatment.

Why Wade’s Restoration of California Is Kensington’s Preferred Mold Remediation Company
Wade Ferris founded this company in 2007, and his name has been on the truck ever since. He works the East Bay hills himself, and he’s been under enough Kensington bungalows to know what a 1930s galvanized supply line looks like when it’s been weeping into a subfloor for a decade. That’s not something you learn from a franchise training video.
Ask anyone on your street. Kensington is the kind of place where neighbors actually talk, and word travels fast when a contractor does right by someone or doesn’t. We’ve built our reputation here one crawl space at a time. Our team is IICRC-certified and RIA-affiliated, background-checked, and uniformed. More importantly, Wade hands you the moisture log at the end of every job. Daily readings, written down. Almost nobody in this trade does that.
When you call, a live person answers. Not a call center, not a voicemail queue. If you call at midnight because a water heater let go above your finished basement, Wade heads out. For mold, the timeline is a little different, but the principle is the same: you’ll know exactly who’s showing up and when.
Our Mold Remediation Services in Kensington
Mold Inspection & Testing
Before we touch anything, we figure out what you’re actually dealing with. That means moisture readings across walls, ceilings, and subfloor framing, plus air sampling when the situation calls for it. In Kensington, inspections routinely reveal mold in places the homeowner never looked: behind baseboards on the downhill side of the house, inside wall cavities fed by hairline chimney cracks, and under floor joists in that 18-inch crawl space. We test, we document, and we show you everything. If you already got a quote from someone else, remember: we offer a free second opinion on any written estimate.
Mold Removal
Mold removal in Kensington is different from flatland work. The homes here sit on slopes, and the marine fog creeps up Colusa Avenue and blankets the hillside most mornings. That means the moisture source is usually humidity, not a single leak. We remove the mold and we fix the ventilation or drainage issue that let it grow, because surface treatment alone won’t last. Containment is set up before we start, and HEPA filtration runs the whole time. Your mold requires more than a wipe-down. We treat it like a real remediation job.
Black Mold Remediation
Black mold (Stachybotrys chartarum) gets a lot of attention, and for good reason. It thrives in chronically damp cellulose, which describes half the crawl spaces and attics in Kensington’s pre-1950 housing stock. We treat black mold the same way we treat every mold problem: find the water, fix the water, remove the contamination, verify with post-remediation testing. The color of the mold matters less than the moisture history behind it, and we document both. If you’re a senior or a veteran, the 10% discount applies here like everywhere else.
Air Quality Restoration
Mold spores travel. We’ve handled Kensington homes where the visible growth was confined to one crawl space, but the air quality in the living room told a different story. Post-remediation air scrubbing with HEPA filtration, often a B-Air GRIZZLY unit running for 24-48 hours, pulls spores and fine particulate out of the air so you’re not breathing the aftermath. We test after the job to show you the numbers came down.

Trusted Brands We Service in Kensington
We work on homes of every era and every level of remodel, and we spec equipment that’s actually rated for the job. On the drying side, we run Dri-Eaz and Phoenix dehumidifiers; for air movement we use XPOWER and B-Air. Our IICRC, RIA, and IFA credentials back the work, which matters when an insurance adjuster is reviewing a claim on aging construction. And because we’re local, we’re not waiting on gear from a warehouse in Sacramento. It’s here, it’s maintained, and it goes on the truck when Wade heads up Arlington Avenue.
Common Mold Remediation Problems We See in Kensington Homes
- Fog-driven humidity in minimally ventilated crawl spaces. Kensington sits in the path of persistent marine layer fog, and crawl spaces with no cross-ventilation become mold incubators. The mold keeps returning because the ventilation was never addressed.
- Tight clearances and zero staging room. Most Kensington streets were laid out in the 1920s with no shoulder and mature tree canopy. A full-size box truck cannot physically reach many homes, so we hand-carry equipment up from lower arterials. It changes how we plan the job.
- Seismic micro-tremors from the Hayward Fault. Hairline cracks in foundations and chimneys allow moisture into wall cavities and subfloor spaces. Mold inspections that ignore this pathway miss the real source.
- Original hardwood floors at risk. Kensington bungalows often have original oak flooring that predates modern subfloor ventilation standards. Aggressive drying or careless containment can cup and warp those floors. We use low-profile drying and exterior subfloor access to protect them.
Pricing for Mold Remediation in Kensington, CA
Here’s what we see in Kensington specifically. A targeted mold removal job in a single bathroom or closet typically runs $1,800-$2,800. A full crawl space remediation with subfloor access from exterior grade, ventilation correction, and post-job air scrubbing lands between $3,500 and $6,500. Attic jobs with fog-driven humidity issues fall in a similar range. What moves the number is access, square footage of contamination, and whether structural wood needs repair. We don’t charge a trip fee inside Contra Costa County, and every estimate is free. Call (855) 915-0646 and Wade will give you a straight number after seeing the job.

FAQs - Mold Remediation in Kensington
Mold remediation in Kensington takes longer because access is harder and the moisture source is usually environmental, not a single leak. Narrow streets with no shoulder mean equipment gets hand-carried, and crawl spaces with less than 18 inches of clearance mean low-profile drying gear and exterior subfloor access rather than roll-in box fans. Add in fog-driven humidity that has to be corrected with ventilation work, and you’re looking at 3 to 7 days on the drying side alone, compared to 2 to 3 days in flatland El Cerrito. Call (855) 915-0646 with any questions, and we’ll walk you through what your specific home needs.
We protect original hardwood floors by never over-drying the subfloor from above. In Kensington’s pre-1950 bungalows, we access the subfloor from exterior grade or through crawl space hatches, place low-profile Dri-Eaz dehumidifiers under the floor, and monitor moisture levels in the hardwood itself daily. If we see the flooring drying faster than the framing, we adjust the air movement. The goal is a dry substructure with no cupping, no warping, and no refinishing needed.
Yes, it absolutely can. Kensington straddles the Hayward Fault, and micro-tremors open hairline cracks in foundations and unreinforced chimneys. Those cracks become moisture pathways into wall cavities and crawl spaces. The mold appears months later, but the root cause is seismic. Most mold inspections in Kensington miss this. We specifically look for it, because we work this ZIP code and we know what the ground does here.
The right way starts with exterior subfloor access or a shallow crawl hatch, not a standard crew trying to squeeze through a 14-inch opening. You need low-profile dehumidifiers, remote moisture sensors because you can’t get eyes everywhere, and a plan to correct the ventilation so the fog-driven humidity stops feeding the mold. We’ve done this work off Cambridge Avenue, off the Arlington, and throughout 94530. This is our normal, not an edge case. Call for a free estimate.
Almost certainly, yes. Mold spores go airborne during remediation, even with containment in place. In Kensington’s tightly built craftsman bungalows, that spore load can linger in the living space for days. We run HEPA air scrubbers, often a B-Air GRIZZLY, for 24 to 48 hours after remediation, and we test the air before we call the job done. If you don’t do this step, you’re breathing spores that settled six feet from where we worked. We won’t skip it, and we’ll show you the before and after numbers.
If you’ve got mold in your Kensington home, the worst thing you can do is wait. The fog isn’t going anywhere, the crawl space isn’t getting bigger, and the spores aren’t stopping at one room. Call (855) 915-0646 and talk to Wade directly. Free estimate, no trip charge in the county, and a written 90-Day Done Right Promise on every job.
