Fast, Reliable Biohazard & Crime Scene Cleanup Across San Lorenzo
Biohazard and crime scene cleanup in San Lorenzo typically costs $1,500-$5,000 for a standard trauma or unattended death cleanup, and most jobs can be started the same day you call. Wade’s Restoration of California has been handling these situations since 2007, and we know the 94580 housing stock well enough to anticipate where contamination hides in a Bohannon tract home before we even walk in. Call (855) 915-0646 anytime, day or night, and Wade himself will answer.
San Lorenzo’s nearly identical 1944-1955 Bohannon tract homes share the same tight crawl spaces and slab-on-grade layouts. That matters more than most people realize when it comes to biohazard work. Blood, bodily fluids, and other contaminants don’t just sit on the surface in these homes. They wick into unsealed concrete slabs, travel along shared wall cavities, and follow under-slab plumbing chases into places you’d never think to look. Our crews have worked enough of these original grid streets that we can pre-diagnose likely secondary contamination just by knowing the address is in the Bohannon tract. That block-by-block familiarity is something a national chain simply doesn’t have, and it’s the difference between a cleanup that lasts and one that comes back as a smell six weeks later.
We’re Biohazard & Crime Scene Cleanup specialists, not carpet cleaners who also dabble. Our work in San Lorenzo covers everything from unattended deaths and crime scenes to hoarding conditions and infectious disease disinfection. If you’re dealing with something traumatic right now, put the phone down and let us handle the details. If you’re researching ahead of time, keep reading and you’ll learn exactly how we approach this work in your specific neighborhood.
Why Wade’s Restoration of California Is San Lorenzo’s Preferred Biohazard & Crime Scene Cleanup Company
Wade Ferris founded this company in 2007 after years of watching national outfits quote one price on the phone and another at the door. He publishes his name, his address, and his license number. He answers his own phone. When you call about a biohazard situation in San Lorenzo, the person you talk to is the same person who owns the company and will likely be standing in your living room within the hour. There’s no call center, no voicemail tree, no “someone will call you back.”
Our reputation in San Lorenzo comes from doing the work right the first time and standing behind it. Every water, fire, and mold job we do carries a written 90-Day Done Right Promise. If something isn’t right, Wade comes back and makes it right. That’s not a slogan. It’s stamped on the contract. For biohazard work specifically, the stakes are higher than any other job we take. You’re not dealing with a wet carpet. You’re dealing with human remains, bloodborne pathogens, or a hoarding situation that’s been building for years. The last thing you need is a crew that treats it like a routine cleaning.
We also know San Lorenzo’s housing stock in a way that out-of-town companies can’t match. The Bohannon homes that fill 94580 were built to the same specs within the same decade. When we walk into a home on Via Manzanas or Bockman Road, we already know what the subfloor looks like, where the slab is unsealed, what’s hiding in the attic clearance, and where fluids typically travel. That local knowledge means we find contamination the first time, not on a callback.
We’re IICRC-certified and RIA-affiliated. Our crew runs Dri-Eaz and Injectidry equipment specifically suited to the low-clearance, slab-on-grade spaces common in San Lorenzo. And we deal with insurance adjusters directly, so you’re never the one stuck relaying information between two parties who aren’t talking to each other.
Our Biohazard & Crime Scene Cleanup Services in San Lorenzo
Crime Scene Cleanup
Crime scene cleanup in San Lorenzo usually means blood, and blood in a Bohannon slab-on-grade home behaves differently than it does in a newer house with sealed concrete. The original 1940s slabs were poured without vapor barriers or sealants, which means fluids soak in and stay. Surface cleaning alone won’t cut it. Our team removes affected materials, decontaminates the concrete with antimicrobial treatments, and verifies the work with ATP testing before we seal the slab. If the scene involves a violent crime, we coordinate with law enforcement and only enter after the scene is released. The last thing we want is to contaminate evidence or interfere with an investigation.

Trauma & Unattended Death Cleanup
Our crew was called to a Bohannon-era home on Via Manzanas after an unattended death. Because the slab-on-grade layout channels fluids toward the low point near the water heater closet, we used Injectidry drying mats and negative air containment to decontaminate the adjacent hall closet and subfloor before sealing the affected concrete with an antimicrobial encapsulant. That’s not a standard procedure in this industry. It’s what San Lorenzo’s housing stock demands. Unattended deaths in these homes often go undiscovered for days or weeks, and by the time we arrive, fluids have moved through the slab, up drywall, and into wall cavities. We remove the affected materials, dry the structure, decontaminate, and return the space to a condition where you can safely walk in without a respirator.

Hoarding Cleanup
Hoarding situations in San Lorenzo’s 900-1,100 sq ft Bohannon homes present a specific challenge: the same tight crawl space that makes these houses affordable also gives mold, rodent activity, and odor nowhere to hide. When a hoard has been in place for years, the weight of accumulated material often causes subfloor deflection, especially over the shallow raised foundation sections. We work with the homeowner or family member to sort salvageable items, remove debris, and then address the underlying contamination. This is not a rush job. It takes patience and a crew that treats the person’s belongings with respect, not a dumpster-and-done mentality.

Blood & Bodily Fluid Cleanup
Blood cleanup in San Lorenzo homes almost always involves unsealed concrete, and that’s where most companies get it wrong. They scrub the surface, hit it with bleach, and call it done. A month later the odor returns. We remove the affected material, physically decontaminate the slab, and verify the results before we rebuild. In the original Bohannon tracts, we also check for shared wall cavities. These homes were built fast and identical, and a blood contamination event in one unit can migrate into a neighbor’s wall space through gaps that were never sealed. We inspect for that every single time.
We also handle infectious disease disinfection, including MRSA, C. diff, COVID-19, and other pathogens. That work is done with EPA-registered disinfectants applied to dwell times that actually kill the organism, not just make the room smell clean. And when tear gas or chemical contamination is involved, we first assess for asbestos-containing duct wrap, which is present in a significant percentage of Bohannon-era homes. Disturbing it during decontamination creates a second hazard, so we identify it before we start and include abatement in the scope if needed.

Trusted Brands We Service in San Lorenzo
We use professional-grade equipment on every San Lorenzo job, including Dri-Eaz drying systems and Injectidry mats for the low-clearance spaces these 1940s homes are known for. Our crews are IICRC-trained, and we follow RIA and IFA protocols for biohazard remediation. What that means for you: the equipment we bring into your home is the same equipment used on commercial restoration projects, not rental-store gear run by someone who watched a YouTube video. We also keep common replacement parts and materials stocked locally, so we’re not waiting on a shipment from a warehouse in another state when your job needs to move fast.
Common Biohazard & Crime Scene Cleanup Problems We See in San Lorenzo Homes
- Fluids wicking into unsealed slab-on-grade concrete. The original Bohannon slabs were poured without vapor barriers, so blood and body fluids penetrate beyond the surface. Standard surface cleaning leaves bio-burden in the concrete that produces persistent odor for months or years afterward.
- Crawl space humidity amplifying contamination. San Lorenzo sits on bay-margin flatlands that trap marine moisture, keeping crawl spaces damp year-round. After a trauma cleanup, that trapped moisture raises indoor spore counts and causes secondary mold on blood-soaked drywall if we don’t dry immediately.
- Asbestos-containing duct wrap disturbed during decontamination. Many Bohannon-era homes in 94580 still have original asbestos-containing duct wrap. Tear gas or chemical decontamination can unknowingly disturb it, forcing emergency abatement that doubles the scope of the job.
- Shared wall cavities spreading contamination between units. These tract homes were built fast and identical, and the wall cavities between adjacent units were rarely sealed. A contamination event in one unit can and does migrate into the neighboring unit’s wall space. We check for this on every job.

FAQs - Biohazard & Crime Scene Cleanup in San Lorenzo
Yes, and significantly. The 1940s-era slabs in these homes were poured without vapor barriers or sealants, which means blood and other fluids soak directly into the concrete rather than pooling on top. Surface scrubbing with bleach will not remove bio-burden that has penetrated an inch or more into the slab. We remove the affected surface layer, apply antimicrobial treatments, verify with ATP testing, and then seal the concrete with an encapsulant. This is standard procedure for us on every blood job in a Bohannon home. Call (855) 915-0646 for a specific assessment of your situation.
Yes. These homes are small, usually 900-1,100 square feet, and years of accumulated material creates structural stress on the subfloor, especially over the shallow raised foundation sections. The tight crawl space also traps moisture and odor, and the original floor framing was not built to handle thousands of pounds of debris. We often find subfloor deflection, rodent infiltration, and mold underneath the hoard. The cleanup requires structural assessment, not just hauling. We handle both in-house.
We identify the duct wrap before we start any decontamination. If asbestos-containing material is present and it has been disturbed or will be disturbed during cleanup, we bring in licensed abatement and include that scope in your written estimate. Tear gas residue bonds to porous surfaces including the duct wrap, so proper decontamination often requires removal and replacement of that material. We won’t disturb it blindly. Call (855) 915-0646 and Wade will walk you through what to expect.
You should expect a crew that understands these homes are not unique to your block. If contamination has traveled into shared wall cavities on your property, it has likely affected the adjacent unit the same way if the event spanned multiple rooms. We inspect the full wall line, not just the obvious affected area. You should also expect that the slab will need more than surface cleaning, and that drying equipment will run for several days after removal. You get a written scope in advance, and the work is covered by our 90-Day Done Right Promise.
Yes, because floodwater from San Lorenzo Creek carries sewage, agricultural runoff, and pathogens that are not present in clean-water leaks. If your home is in the creek-corridor flood zone and you’ve had water intrusion, you should treat it as a potential infectious disease exposure, not just a water removal job. We disinfect with EPA-registered antimicrobials, dry the structure completely, and document the entire process for your insurance adjuster. The creek’s flood risk is real, and the contamination risk that comes with it is real. Call (855) 915-0646 for a free assessment.
