Why Wade’s Restoration of California Is Sonoma’s Preferred Mold Remediation Company
Wade’s Restoration has been doing Mold Remediation work in Sonoma for years, and the reason homeowners keep calling us back is simple: Wade puts his name, his address, and his license number on every job, and he answers his own phone. You’ll never get bounced through an answering service. You call, Wade picks up, and he’s honest about what he can do and what it’ll cost.
Sonoma homeowners have dealt with national franchises that quote one price over the phone and a different one at the door. That’s not how we work. Wade gives you a written scope before any work starts, walks you through the moisture readings he takes every single day, and hands you the full document log when the job is done. Almost nobody in the trade does that. Ask anyone on your street who’s dealt with post-wildfire moisture issues in this valley. They’ll tell you the same thing.
Our crew is background-checked, uniformed, and trained on the equipment we bring into your home: Dri-Eaz dehumidifiers, Phoenix air movers, Injectidry drying panels, and XPOWER fans. We’re IICRC-certified and RIA-affiliated, and we carry that standard on every Sonoma job, whether it’s a wine cellar off East Napa Street or a ranch house off Arnold Drive.
Our Mold Remediation Services in Sonoma
Mold Inspection & Testing
Before we remove anything, we find out what we’re dealing with. Sonoma homes, especially older adobe and Victorian structures around the Plaza and wood-frame builds throughout 95476, hide moisture in places no visual inspection will catch. We use moisture meters and thermal imaging to map where water has traveled inside wall cavities and under flooring. If testing is needed, we collect samples and send them to a third-party lab. You get results you can read, not a sales pitch.

Mold Removal
Removal means containment first. We seal off the affected area with polyethylene sheeting and negative air pressure so spores don’t spread through your HVAC system while we work. Then we remove affected drywall, insulation, carpet, or cabinet materials, bag them, and treat the remaining structure with an EPA-registered antimicrobial. In Sonoma, we see a lot of hidden mold behind original plaster and lathe in older homes near the Plaza, where a small leak has been feeding growth for years without anyone noticing.

Black Mold Remediation
Stachybotrys, the black mold you hear about, needs constant moisture and cellulose to grow. We find it most often in Sonoma crawl spaces where morning fog from San Pablo Bay keeps humidity elevated for months at a time, and in bathrooms without proper ventilation in older ranch homes. We treat it the same way we treat any toxic mold: containment, removal, cleaning, and drying. Then we document the before, during, and after so you know exactly what was found and what was done.

Air Quality Restoration
Mold spores don’t just live on surfaces. They ride through your ductwork and settle back onto clean surfaces weeks after remediation is “finished.” After we’ve removed the mold and dried the structure, we clean the air itself using HEPA-filtered air scrubbers. This matters more in Sonoma than almost anywhere else in the North Bay, because the 2017 Nuns Fire left fine ash particulate embedded in HVAC systems all over town. We test air quality before clearing a job, and we don’t clear it until the numbers prove it’s clean.

Trusted Brands We Service in Sonoma
We bring professional-grade equipment from Dri-Eaz, Phoenix, Injectidry, and XPOWER onto every Sonoma job, and we keep replacement parts and filters stocked in our Bay Area office so crews can roll to 95476 without waiting on a warehouse shipment. That’s the difference between a franchise that subcontracts and shows up with rental dryers, and Wade’s crew showing up with equipment calibrated for the humidity cycles this valley throws at homes. We’re IICRC-certified, RIA-affiliated, and IFA-recognized, which means the equipment and the training meet industry standards, not someone’s marketing budget.
Common Mold Remediation Problems We See in Sonoma Homes
- Post-Nuns Fire ash residue in wall cavities. After 2017, we learned that homes with zero structural fire damage still had HVAC systems and wall voids packed with fine smoke particulate. That ash holds moisture, traps humidity, and feeds mold long after the smoke clears. We treat ash cleanup as standard practice on any Sonoma job within a mile of the surrounding hills.
- High-pressure extraction on adobe and old lime plaster. Thick earthen walls near the Plaza absorb water differently than drywall. Blasting them with high-pressure extraction erodes the material and pushes moisture deeper. We use lower-pressure methods and longer dry times for unreinforced masonry, then verify with moisture meters before closing anything up.
- Fog-driven crawl space humidity. The morning fog that rolls north from San Pablo Bay through the Carneros lowlands keeps crawl spaces in Sonoma damp for much of the year. After any plumbing leak or roof drip, that humidity accelerates mold growth fast. We recommend crawl space encapsulation and dehumidification more often here than in Petaluma or Rohnert Park, where the fog sits differently.
- Wine cellars excluded from containment. This one is Sonoma-specific. A wine cellar full of bottles and wooden racks that were never cleaned after the Nuns Fire will reintroduce spores into a remediated home. We include wine cellars in containment protocols and treat ash-laden bottles and racks as part of the job. Skipping this step is how you get a failed clearance test.
Pricing for Mold Remediation in Sonoma, CA
Here’s what you can expect to pay in Sonoma right now. A contained bathroom or closet remediation runs $1,800 to $3,200. A standard room with drywall removal and treatment lands between $2,500 and $5,500. Crawl space mold remediation, which almost always includes encapsulation and dehumidifier installation in this fog zone, runs $4,500 to $9,000 depending on square footage and access. Whole-home remediation after a major water event typically starts around $6,000 and goes up from there. What moves the number: how far the moisture traveled, whether adobe or lath-and-plaster walls are involved, whether your wine cellar needs cleaning, and how long the leak has been active. We give you a written scope with pricing before any work starts. No trip charge inside our own county. Call (855) 915-0646 for a free estimate, and remember: any repair over $200 gets $40 off, and seniors and veterans always get 10% off.

FAQs - Mold Remediation in Sonoma
Yes. Homes across Sonoma 95476, even those with no structural fire damage, absorbed fine smoke ash into wall cavities, attics, and HVAC systems during the Nuns Fire. That ash traps moisture and provides a food source for mold, meaning remediation here has to address smoke particulate first or the mold returns. We treat ash cleanup as part of any mold job within a mile of the burn zone hills.
We use low-pressure drying and longer dry times, not high-pressure extraction, because unreinforced adobe and old lime plaster erode under pressure and trap moisture deeper inside the wall. After a roof leak in a pre-1900 Victorian near the Plaza, our crew mapped moisture behind original plaster and found elevated humidity feeding Penicillium in the horsehair insulation. We set up a Dri-Eaz LGR 7000XLi and an XPOWER X-2580 to dry the cavity, then used Injectidry panels to pull moisture from the adobe foundation before treating the remaining mold. That’s the method these walls require.
Yes. We contain the cellar, clean ash and mold from bottles, racks, and wall surfaces without introducing heat or chemicals that would affect the wine, and run HEPA air scrubbers to clear the air. The bigger risk is skipping the cellar entirely: ash-laden bottles reintroduce spores after clearance, and you fail the post-remediation test. Call (855) 915-0646 and Wade will walk you through what your cellar needs.
The fog that rolls north from San Pablo Bay through the Carneros lowlands keeps crawl space humidity elevated for much of the year, even in summer. That’s why we recommend crawl space encapsulation and dehumidification more often in Sonoma than in nearby cities. If your crawl space smells musty from June through September, that fog is a contributing factor, and the mold isn’t going to dry out on its own.
We visually identify and sample suspect growth, then send samples to a third-party lab for confirmation before and after remediation. You get the lab report in writing. If Stachybotrys is present, we follow full containment and removal protocols, then verify clearance with air sampling. Estimates are free, and Wade himself reviews every report before he signs off on a job.
