Why Wade’s Restoration of California Is Brentwood’s Preferred Biohazard & Crime Scene Cleanup Company
Wade Ferris started this company in 2007 and still runs it himself. Not from a call center. Not through a franchise playbook. If you call the number, you’ll get Wade or someone standing next to him. That’s how it works. Ask anyone on your street who’s dealt with a restoration company, and the stories you’ll hear are about national outfits that quoted one price on the phone and a different one at the door. We don’t do that. The price Wade writes down is the price you pay.
Brentwood customers keep our number for one reason: we show up. A trauma scene in a Garin Ranch home at 2 a.m. doesn’t wait for business hours. Neither do we. Our Biohazard & Crime Scene Cleanup team knows the streets out here - Balfour Road at rush hour, the loop through the Streets of Brentwood, the twist of Fairview Avenue up toward the hills. That local knowledge means a faster response when every hour counts.
Reviews from Brentwood homeowners consistently mention two things: Wade’s crew arrived when they said they would, and the owner checked in personally before the job wrapped. You’ll find us background-checked, uniformed, and IICRC-certified with RIA affiliation. But the credential that matters most out here is a published name and a face you’ll run into again at the Harvest Market.
Our Biohazard & Crime Scene Cleanup Services in Brentwood
Crime Scene Cleanup
When a crime scene happens in a Brentwood home, the police finish their work and leave. The biohazard remains. Blood, bodily fluids, and tissue can soak through carpet, padding, and into the concrete slab below. In most Brentwood homes, that slab sits on expansive clay soil that has been cracking and shifting for 20-plus years. Those hairline cracks become contamination channels. Our crew treats the entire pathway - visible and below the surface. We handle it discreetly, with unmarked vehicles when needed.

Trauma & Unattended Death Cleanup
An unattended death in a 2004 stucco tract home in the Garin Ranch area of 94513 taught us more about Brentwood construction than any training manual could. Decomposition fluids had seeped through carpet and padding into the slab’s hairline cracks caused by expansive clay soil cycling. Our crew used Dri-Eaz negative air machines and Injectidry drying mats after removal, then treated the exposed bottom plates and weep-screed-line studs where the same soil movement had pulled the stucco below grade. Without that treatment, odor would have wicked into the wall cavity and kept coming back for months. That’s the difference local experience makes.
Decomposition in a Brentwood summer is different from anywhere on the coast. When attics hit 110°F, gases expand and move. They travel through shared wall chases, through return air paths, into rooms that had no contact with the original scene. If the crew treats only the visible area, you’ll be chasing odor through the whole house. We map the entire air path before we start.

Hoarding Cleanup
Hoarding situations in Brentwood are complicated by the size of the homes. A 3,000-plus square foot tract house holds a lot more material than a 1,200 square foot bungalow. That means more animal waste, more trapped moisture, more hidden contamination. We regularly find biohazard material behind failed stucco weep screeds at grade, where fluids have wicked into wall cavities through cracks that nobody could see. You can’t clean what you don’t find. We find it because we know where these homes hide their problems.

Blood & Bodily Fluid Cleanup
The biggest mistake we see is homeowners attempting a bleach cleanup on porous slab concrete. Bleach drives proteins deeper into the concrete rather than removing them. In Brentwood’s clay soil conditions, those same slab cracks are already opening and closing with seasonal moisture swings. What seems like a cleaned surface becomes a permanent odor source that reactivates with every heat wave. We remove contaminated material properly, treat the affected concrete, and verify with porosity testing before rebuilding.

That saves time on every dispatch.
Common Biohazard & Crime Scene Cleanup Problems We See in Brentwood Homes
- Slab crack contamination: Brentwood’s expansive clay soils expand in winter and contract in summer, opening and closing hairline cracks in the concrete slabs under most 1995-2008 homes. Blood, bodily fluids, and decomposition byproducts follow those cracks into places surface cleaning never reaches.
- Stucco weep screed wicking: On 2000s-era homes, years of soil movement settle the weep screed to grade or below. Fluids at wall bases get wicked behind the stucco into the stud cavity. A biohazard release near an exterior wall often has a hidden second contamination site inside that wall.
- 110°F heat and odor migration: Brentwood’s inland location traps heat in a way no Bay Area city west of the hills experiences. During 100°F-plus stretches, decomposition gases expand and travel through wall chases, electrical penetrations, and shared HVAC returns into rooms that had no direct contact with the scene.
- Shared chase ways in tract construction: Because Brentwood’s subdivisions were built in tight waves of near-identical floor plans, many homes share the same chase-way layouts. Contamination that follows a plumbing or electrical chase can surface in an upstairs bedroom even when the originating scene was in a downstairs room. Generic crews don’t check for this.

FAQs - Biohazard & Crime Scene Cleanup in Brentwood
Brentwood’s expansive clay soils open hairline cracks in slab foundations during seasonal moisture swings, and those cracks become pathways for blood and bodily fluids to travel below the surface where surface cleaning never reaches. We treat the concrete itself, not just what’s on top of it, using porosity testing to verify the contamination is removed before anything gets rebuilt over it. Call (855) 915-0646 and we’ll assess exactly what your slab is doing.
Yes. Brentwood routinely hits 105-110°F in summer, far hotter than coastal Contra Costa cities, and that heat accelerates decomposition gases and drives them through shared wall chases into adjacent rooms and upstairs spaces. A scene that sits for 24 hours in Brentwood heat behaves like three days in a coastal city. The sooner we start, the less area we have to treat. Call the minute you know something happened.
Yes, and it happens more often than homeowners expect. In Brentwood’s 1995-2008 tract homes, years of soil movement settle the stucco weep screed to grade or below it, and animal waste or fluids at wall bases get wicked behind the stucco into the stud cavity. Our hoarding cleanups include checking these hidden pathways before we call the job done. If we skip it, the odor returns. We don’t skip it.
We start with a full site assessment that maps contamination spread, including where decomposition gases may have traveled through the home’s air paths. Then removal of affected materials, negative air containment to keep other areas clean, slab treatment if fluids reached concrete, wall cavity inspection with particular attention to weep screed lines and bottom plates, and finally verification testing. In a large Brentwood home, the process usually runs 2-4 days including equipment drying time. A written scope is in your hands before anything starts.
Brentwood follows Contra Costa County standards for biohazard waste handling and disposal, and any structural demolition that follows cleanup - removing contaminated drywall, base plates, or stucco sections - generally requires a permit. We handle the paperwork and the disposal properly, so you’re not left holding bags of regulated waste or an unpermitted demolition on your permit history. If you have questions about a specific situation, call (855) 915-0646 and Wade will talk you through it.
