Mold Remediation – Kensington typically costs $1,800 – $4,500 for whole-home treatment, with localized removal starting around $650.

Call (361) 317-7269 for a free written estimate.
Kensington sits tucked against the East Bay hills where marine air meets warmer inland temperatures, creating exactly the kind of temperature differential that drives condensation inside wall cavities. We’ve worked on enough homes near Kensington Road and the Colusa Circle area to know where moisture hides in this specific terrain. Our Mold Remediation team doesn’t guess. We map moisture with thermal imaging, document everything for your insurance adjuster, and put the full scope and price in writing before we start remediation.
Why Keegan Water Damage Restoration Is Kensington’s Preferred Mold Remediation Company
We’ve built our reputation in Kensington by showing up inside the window we gave you and leaving the site clean. That’s The Garrison Standard, and it’s how we’ve operated since joining the Garrison Partners family in 2005.
Our technicians know the local building stock. Kensington’s hillside homes, many dating to the 1920s through 1950s, were built with minimal vapor barriers and often have crawl spaces that trap moisture from the clay-heavy soils on the north slope. We’ve remediated mold in bungalows off Santa Fe Avenue and in mid-century ranch homes near Kensington Hilltop Elementary where poor drainage created chronic humidity problems. This isn’t theoretical knowledge. It’s from walking the same streets and seeing the same patterns repeat.
When water damage precedes mold growth, we also handle Water Damage Restoration in Kensington to stop the source before remediation begins. And for homes dealing with fire damage that was extinguished with water, creating secondary mold issues, we offer Fire Damage Restoration in Kensington as part of our complete recovery service.
Every call reaches a live person, 24/7, including nights and holidays. No phone trees. No callback queues. When mold is spreading behind your drywall, you need a voice on the line, not a recording.
Mold Remediation Services in Kensington
Mold Remediation Services in Kensington cover the full protocol from containment and air filtration through demolition, cleaning, and post-remediation verification. For fire-related damage, see our Fire Damage Restoration in Kensington. A typical whole-home remediation in Kensington runs $1,800 – $4,500 depending on square footage and whether HVAC systems are involved. We see the highest demand in spring after winter rains saturate the hillside soils, and again in fall when temperature inversions trap humid air against the Berkeley Hills.
Containment and Negative Air Pressure
We seal the work zone with polyethylene sheeting and run HEPA-filtered negative air machines to prevent spore migration. In Kensington’s tighter floor plans, especially the older homes off Arlington Avenue, this step is critical because rooms connect through original ductwork that wasn’t designed for modern isolation.
Post-Remediation Verification Testing
We don’t declare the job finished on a visual check alone. Third-party lab testing confirms airborne spore counts have returned to normal levels, documented for your records and your insurance claim.

Professional Mold Removal in Kensington
Professional Mold Removal in Kensington addresses active mold colonies through physical removal, not just surface cleaning or painting over the problem. Localized removal of a single bathroom or closet area typically runs $650 – $1,400, while crawl space treatment starts around $1,200 and can reach $3,200 if structural wood requires sanding or replacement. We use this service when mold is visible and contained, before it has colonized HVAC systems or spread through wall cavities.
Structural Drying Before Removal
Mold returns if moisture remains. Our crews deploy Dri-Eaz and Phoenix dehumidification systems to drop ambient humidity below 60% before we remove a single colony. In Kensington’s microclimate, where fog rolls in from the Bay and lingers against the hills, this step often takes longer than inland locations.
Antimicrobial Treatment of Framing
After removal, we apply EPA-registered antimicrobials to bare wood and concrete. This isn’t a coating that hides future growth. It’s a treatment that alters the surface chemistry to resist re-colonization, backed by our 365-Day Done Right Promise.
Trusted Brands We Service in Kensington
Our equipment roster draws from the brands used in IICRC-standard restoration work nationwide: Dri-Eaz, Phoenix, and XPOWER dehumidifiers and air movers. We maintain these machines locally, which means faster deployment to Kensington when humidity readings spike after a leak. For crawl space jobs near the Colusa Circle or hillside homes off Amherst Avenue where access is tight, we use Injectidry specialty drying systems that thread hoses into wall cavities without demolition. Stocking parts for these units locally cuts our repair and maintenance turnaround, so the equipment is ready when your home needs it. Every machine is operated under IICRC, RIA, and IFA guidelines, with readings logged to support your insurance documentation.
Common Mold Remediation Problems We See in Kensington Homes
- Crawl space moisture from hillside drainage. Kensington’s north-facing slopes collect groundwater that wicks into crawl spaces through foundation vents. We regularly find Cladosporium and Penicillium colonies on floor joists in homes near Kensington Road where the grade drops sharply toward the rear property line.
- Vintage plaster and lath retaining moisture. Pre-1960 Kensington homes often have horsehair plaster that holds humidity for weeks after a leak. Surface mold appears on the exterior wall paint while the real colony spreads through the lath cavity.
- Fog belt condensation in uninsulated attics. Marine layer fog penetrates east from the Bay, cooling attic sheathing below the dew point on summer mornings. We’ve treated attic mold in ranch homes near Santa Fe Avenue where inadequate ventilation met this exact pattern.
- Post-fire water damage creating secondary mold. After a fire is extinguished, standing water in walls and flooring creates ideal conditions within 48 – 72 hours. We coordinate with our fire restoration division to dry structures before mold establishes.
