Fast, Reliable Mold Remediation Across San Lorenzo
Mold remediation in San Lorenzo usually costs between $1,200 and $4,500, and for homes in the Bohannon tracts, the work almost always involves more than just killing visible mold. Most jobs we handle in 94580 come down to two things: a crawl space that stays damp because of bay-margin humidity, and 1940s construction details that trap moisture exactly where mold likes to grow. We know these houses because we’ve worked on hundreds of them. If you’ve spotted black staining on baseboards, a musty smell you can’t place, or condensation that never really dries, call (855) 915-0646 and Wade will walk you through what’s happening before you spend a dime.
Why Wade’s Restoration of California Is San Lorenzo’s Preferred Mold Remediation Company
Wade Ferris started this company in 2007 and he still answers his own phone. That matters in San Lorenzo, where a lot of homeowners have already been through the national-chain runaround: a quote on the phone, a different number at the door, and a crew you never see again. Wade lives by a simpler rule. His name is on the truck, his address is published, and he’s going to run into you again at the grocery store on Hesperian Boulevard. That’s the oldest accountability mechanism there is, and it’s why people on Bockman Road and Via Arriba call us first.
Every mold job we do in San Lorenzo comes with the 90-Day Done Right Promise in writing. If it’s not done right, we make it right. No fine print, no loophole. We also hand you the moisture log at the end of the job. Wade takes readings every single day, and you see exactly what was done, where it was wet, and where it ended up dry. Almost nobody else in the trade does that. And when your insurance company needs documentation, Wade talks to the adjuster directly. You don’t get stuck relaying messages between two sides.
Our Mold Remediation Services in San Lorenzo
Mold Inspection & Testing
Before we touch anything, we figure out what you’re actually dealing with. In San Lorenzo, that means checking crawl spaces, under-sink cabinets, behind the water heater, and the low-pitch attic spaces that Bohannon homes are famous for. We test for mold species like Aspergillus, Penicillium, and Stachybotrys, and we tell you plainly whether you need full remediation or just a good cleaning. A straight answer, not a scare tactic.
Mold Removal
Our Mold Remediation crew removes contaminated drywall, insulation, and framing using full containment so spores don’t spread through the rest of your house. In San Lorenzo’s 900-to-1,100-square-foot tract homes, we’re careful about how we set up containment because there’s not a lot of extra room to work with. The goal is clean air, not a construction zone that lingers for weeks.
Black Mold Remediation
Black mold is a serious thing, but it’s also a term that gets thrown around loosely. We treat every case with containment, HEPA filtration, and antimicrobial application, then we tell you honestly what we found. In San Lorenzo, black mold most often shows up in crawl spaces where slab-on-grade foundations have wicked moisture up through the concrete for decades. You might not see it, but you’ll smell it.
Air Quality Restoration
After the mold is gone, the air in your home still carries spores, VOCs, and whatever else was brewing. We run HEPA air scrubbers and take air samples before and after the job so you can see the difference in writing. For San Lorenzo homeowners with allergies, asthma, or just a nose that knows something’s off, this is the step that makes your house feel like yours again.
Crawl Space Treatment
This deserves its own mention because it’s the number one mold source in 94580. Bohannon homes were built slab-on-grade with shallow raised foundations in some sections. Bay-margin humidity keeps those spaces damp nearly year-round. We dry them out, treat the framing, and install vapor barriers so the mold doesn’t come back.
Moisture & Humidity Control
If you only kill the mold but don’t control the moisture, you’ll be calling us again in six months. In San Lorenzo, we often recommend whole-home dehumidifiers, crawl space encapsulation, and ventilation improvements sized for a 900-to-1,100-square-foot home. It’s not flashy work, but it’s the work that actually solves the problem.

Trusted Brands We Service in San Lorenzo
We use professional-grade equipment from Dri-Eaz, XPOWER, Injectidry, and B-Air on every San Lorenzo job, and our crew holds IICRC credentials. The equipment matters because the drying matters. A box fan from the hardware store will not dry out a crawl space under a Bohannon tract home. We stock the consumables and replacement parts we need for most jobs in the county, so we’re not waiting on a shipment while your subfloor keeps feeding mold.
Common Mold Remediation Problems We See in San Lorenzo Homes
Here’s what we regularly find on streets like Via Manzanas, Paseo Grande, and along San Lorenzo Creek:
- Shared Bohannon construction timeline: Nearly every home in San Lorenzo was built between 1944 and 1955 using identical wood-frame stucco construction. A subfloor mold pattern or failing roof-to-wall flashing found on one street is almost certainly replicated on the next block over. We can pre-diagnose likely secondary damage just by knowing the address is in the original tract grid.
- Asbestos and lead complications: Disturbing 1940s-era vinyl-asbestos floor tiles or lead paint during mold removal without proper containment can shut down a job and create legal liability. This is not optional bookkeeping; it’s a safety and compliance issue on nearly every water or mold job in San Lorenzo.
- Bay-margin humidity that never lets up: San Lorenzo sits on flatlands that trap marine moisture year-round. Crawl spaces stay damp even without a leak. Spraying antimicrobial on visible mold without installing a vapor barrier or improving ventilation means mold returns within months.
- San Lorenzo Creek flood exposure: Properties near the creek sit in documented Special Flood Hazard Areas on FEMA maps. When atmospheric rivers push the creek toward flood stage, those homes take on water through foundations and crawl space vents, and mold follows within days if drying doesn’t start fast.

FAQs - Mold Remediation in San Lorenzo
Because bay-margin humidity keeps crawl spaces and low-pitch attics damp year-round, and the slab-on-grade and shallow raised foundations in Bohannon homes wick moisture up through hairline cracks even when there’s no leak. The fix is drying the space below 50% relative humidity and installing a vapor barrier, not just killing visible mold-similar to how Sewage Cleanup in San Lorenzo requires thorough drying, not just surface treatment. Call (855) 915-0646 and Wade will explain what’s happening in your crawl space specifically.
Yes. Properties in the creek corridor sit in active FEMA Special Flood Hazard Areas, and when atmospheric river storms push the creek toward flood stage, water enters through foundations and crawl space vents. Mold starts colonizing wet wood within 48 to 72 hours. If you’re creek-adjacent, call us before the water recedes so we can start drying immediately. Our Mold Remediation team handles flood-related mold in San Lorenzo regularly. Call (855) 915-0646 for a free estimate.
If you live in the original Bohannon tract grid and your home was built between 1944 and 1955, the construction is nearly identical to your neighbors’. When we find a subfloor mold pattern on one street, we often find the same pattern three doors down. Wade can tell you whether yours matches what he’s already seeing on your block, and that knowledge saves you money on diagnosis. Call (855) 915-0646.
Yes, and this is one of the biggest risks in San Lorenzo specifically. Bohannon-era homes almost always contain asbestos floor tiles, asbestos-containing duct wrap, or popcorn ceilings, and lead paint is standard. Disturbing those materials without proper containment during mold removal or Biohazard & Crime Scene Cleanup in San Lorenzo creates legal liability and health risks. Our crew is trained to test before we disturb, contain properly, and document everything for your insurance. Call (855) 915-0646 with questions; Wade will give you a straight answer.
Most crawl space jobs in 94580 finish in two to four days from setup to final air clearance. The drying phase takes the longest, especially in bay-margin humidity, which is why we use Dri-Eaz dehumidifiers and XPOWER air movers sized for the space. We’ll give you a written timeline before we start and a daily moisture log while we work. Call (855) 915-0646 for a walkthrough of what your specific crawl space will take.
