If you’re seeing black spots around baseboards, smelling something musty that won’t go away, or your home took on smoke during a recent fire season, call Wade’s Restoration of California at (855) 915-0646. Wade Ferris answers his own phone, and he’ll tell you straight what you’re dealing with before anyone sets foot on your property.
Why Wade’s Restoration of California Is Sonoma’s Preferred Mold Remediation Company
Wade Ferris founded this company in 2007, and he still runs it himself. That matters in a town like Sonoma, where a bad restoration job gets talked about at the farmers market by lunchtime. When you call, you get Wade. When his crew shows up, they’re background-checked and uniformed, and they know the difference between a 1920s Victorian on Spain Street and a 1970s ranch out near Maxwell Farms Regional Park. That local knowledge changes how we approach every job.
Sonoma homeowners have been burned before, not by mold, but by outfits that quote one number on the phone and a completely different one at the door. Wade does written scopes before work starts. Every mold job carries the 90-Day Done Right Promise in writing: if it’s not right, Wade comes back and makes it right. He also hands you a daily moisture log, every reading, no games. That’s the kind of accountability you only get from a guy whose name is on the truck and who you’ll run into at the hardware store next Saturday.
Calls are answered by a live person 24/7. If you call during a foggy morning when you just discovered mold behind the washing machine, Wade or one of his crew heads out to your place, usually within the hour. Sonoma is not a far-flung outpost for us. We dispatch from the San Francisco Bay Area office and have crews serving Sonoma daily.
Our Mold Remediation Services in Sonoma
Mold Inspection & Testing
Before anyone rips out drywall, you need to know what you’re actually dealing with. In Sonoma, that means more than just moisture mapping. We test for soot and ash residue in wall cavities and crawl spaces because after the 2017 Nuns Fire, many homes with zero structural damage still had HVAC systems and wall cavities saturated with fine particulate. That soot feeds mold later, even without a visible leak. Our IICRC-certified techs use thermal imaging and moisture meters to find where mold is hiding, then we give you a written scope with photos, so you see exactly what we see.
Mold Removal
Mold removal in Sonoma homes is not a one-size job. A mid-century ranch near Sassarini Elementary has different wall assemblies than a pre-1900 adobe near the Plaza. We use HEPA vacuums, containment barriers, and negative air pressure to keep spores from spreading to clean rooms while we work. Dri-Eaz dehumidifiers pull moisture from the air and structure. All affected material goes out in sealed bags, not through your living room.
Black Mold Remediation
Black mold, or stachybotrys, shows up in Sonoma more often than people expect, particularly in homes that sat with elevated humidity after a water event or wildfire smoke exposure. Black mold is not something to scrub with bleach and forget. It requires full containment, HEPA filtration, and proper disposal. Wade’s crew has handled black mold in crawl spaces under Boyes Hot Springs homes, in wine cellars off East Napa Street, and in bathrooms throughout the 95476 zip code. The process is methodical: isolate, remove, clean, dry, verify. You get clearance testing at the end before we call it done.
Air Quality Restoration
After mold is removed, the air in your home can still carry spores, musty odors, and, in Sonoma specifically, smoke particles from Diablo wind events. We run XPOWER air scrubbers and HEPA filtration units during and after remediation to pull those contaminants out of your living space. For homes near the hills, this step matters more here than in flatland cities. Smoke residue hangs in wall cavities and ductwork long after the fire season ends, and it feeds mold during foggy winters. Air quality restoration is not an add-on. Around here, it’s part of the job.
Crawl Space Treatment
Crawl spaces in Sonoma 95476 take a beating. Morning fog rolls up from San Pablo Bay through the Carneros lowlands and keeps the humidity high. Add fine ash from wildfire seasons settling on joists and insulation, and you have a recipe for hidden mold colonies. Wade’s crew treats crawl spaces with mold-specific antimicrobials after removing contaminated insulation and debris, then we seal and control moisture so the problem doesn’t come back in six months. We also handle moisture and humidity control in crawl spaces as a stand-alone service, because in Sonoma’s climate, the crawl space is where mold starts.
Moisture & Humidity Control
Sonoma’s Mediterranean climate means dry summers and wet winters, with roughly 25 inches of rain annually. That cycle drives moisture into crawl spaces, basements, and older wall assemblies. We install and service dehumidifiers, vapor barriers, and ventilation systems designed for this specific climate. If you’re in a hillside home outside the Plaza or a valley property off Arnold Drive, the humidity profile differs. Wade’s team measures, monitors, and adjusts, and you get the full moisture log at the end.

Trusted Brands We Service in Sonoma
We run Dri-Eaz and XPOWER equipment because it holds up to the demands of adobe, Victorian, and wine-country estate properties we work on around Sonoma. Wade is IICRC-certified and RIA-affiliated, and his crew trains on the same gear the industry sets its standards by. If your home has existing dehumidifiers, scrubbers, or ventilation systems from brands like Phoenix or B-Air, we service those too. For Sonoma customers, we keep common parts stocked, which means less waiting when a unit fails during a foggy stretch. We also offer a Mold Remediation inspection that includes a full equipment check, so you know what’s working and what will fail before you need it.
Common Mold Remediation Problems We See in Sonoma Homes
- Smoke residue feeding mold without a leak. After the Nuns Fire, many Sonoma homes had wall cavities and crawl spaces full of fine ash. That organic material holds moisture and feeds mold during foggy months, even when there’s no water intrusion. We test for soot as part of every mold inspection in the 95476 zip code.
- Improper drying methods on adobe and unreinforced masonry. Thick earthen walls near the Plaza don’t dry like drywall. Standard drying techniques trap moisture deep inside those walls, and mold blooms months later. We use thermal imaging and dehumidification calibrated for historic materials.
- Neglected crawl spaces after smoke events. Ash settles on joists and insulation, then winter humidity does the rest. Nearly every hillside home we inspect in Sonoma has some level of crawl space contamination, and most homeowners never look down there until the smell comes up through the floor.
- Recurring mold after a “surface only” treatment. A company comes in, wipes visible mold with a chemical, and calls it done. The spores in wall cavities and ductwork stay. Three months later, the mold is back. Wade’s 90-Day Done Right Promise exists because too many Sonoma homeowners have lived through exactly that.

FAQs - Mold Remediation in Sonoma
How does wildfire smoke damage lead to mold growth in Sonoma homes?
Wildfire smoke leaves behind fine ash and soot particles that settle inside wall cavities, crawl spaces, and ductwork. That residue is organic material, and when Sonoma’s foggy winters push humidity up, it becomes a food source for mold, even without a visible leak. We test for soot first, then map moisture, because in Sonoma you can’t treat mold without addressing the smoke legacy. If you’ve had smoke in your home and now smell something musty, call (855) 915-0646 for a free estimate.
Can mold remediation be done on historic adobe or Victorian homes in Sonoma without damaging original materials?
Yes. Wade’s crew treats pre-1900 adobe, Victorian, and unreinforced masonry homes regularly, and the approach is completely different from standard drywall remediation. We use controlled dehumidification with thermal imaging to map moisture through thick earthen walls, then HEPA vacuuming and soda blasting to remove mold from surfaces without touching the historic plaster or adobe underneath. It takes longer and costs more, but the original materials are preserved. Call (855) 915-0646 to schedule an inspection of your historic home.
How do you treat crawl spaces in Sonoma that have both mold and wildfire ash accumulation?
We remove contaminated insulation and debris first, then HEPA vacuum all joists and surfaces to pull out fine ash, then apply a mold-specific antimicrobial treatment. After that, we install or repair vapor barriers and dehumidification to keep the crawl space dry through Sonoma’s foggy months. This is not a one-visit job; we monitor moisture daily and hand you the full log. For a crawl space assessment in the 95476 zip code, call (855) 915-0646.
After mold remediation, how do you restore indoor air quality in a Sonoma home that also has smoke odors?
We run XPOWER air scrubbers and HEPA filtration units during and after mold removal to pull out spores and smoke particles from the air. If ductwork is contaminated, we clean it or recommend replacement. In Sonoma homes near the hills, smoke odor reduction is part of the air quality restoration, not an add-on. The goal is to get your indoor air cleaner than it was before the mold showed up. Call (855) 915-0646 to talk through what that looks like for your home.
Is mold remediation more complicated after a wildfire if my home had no structural fire damage?
Yes, because smoke and ash infiltrate places fire never touches: wall cavities, crawl spaces, HVAC systems, wine cellars. Many Sonoma homes with zero structural damage after the Nuns Fire still had fine particulate throughout the building envelope. That residue holds moisture and feeds mold later. We treat every post-wildfire home as a potential mold site, even when the visible damage is minimal. If you’re unsure what’s in your walls, call (855) 915-0646 and ask Wade for a soot and mold assessment.
