Fast, Reliable Mold Remediation Across Sausalito
Mold remediation in Sausalito typically costs $1,800 to $6,500 depending on the size of the affected area, with crawl space jobs starting around $1,400 and whole-home floating-home remediations running $8,000 to $20,000 due to marine enclosure requirements. We can usually have a crew at your door within 90 minutes of your call, and every job starts with a written scope and a moisture log you keep. Call (855) 915-0646 and Wade will walk you through what he’s seeing before anyone steps foot on your property.
Sausalito is not like the rest of Marin County. The fog rolls through the Golden Gate and hangs over Richardson Bay, the salt lands on every surface, and the humidity stays high enough that mold gets a head start before you even notice the leak. We work the hillside homes off Bridgeway and the floating-home docks at Waldo Point Harbor, and we know what each one demands. If you’ve got mold behind a galley bulkhead or creeping up a post-and-pier foundation wall, you need someone who has actually done this work here, not a crew driving over from the East Bay with standard equipment and a generic playbook.
Why Wade’s Restoration of California Is Sausalito’s Preferred Mold Remediation Company
Wade Ferris has been running this company since 2007, and his name is on the truck, his number is on the card, and he answers his own phone at 2 a.m. when a Sausalito homeowner finds water running through a light fixture. Ask anyone on your street. The people around here have dealt with the national chains that quote one price over the phone and show up with a different number and a clipboard. Wade’s not that guy. He writes the scope before the work starts, and he hands you a daily moisture log at the end of the job because almost nobody in this trade does that.
We serve the 94965 and 94966 ZIP codes, from the hillside neighborhoods above Caledonia Street down to the floating-home communities at Waldo Point. Our crews are background-checked and uniformed, and they run Dri-Eaz and Phoenix equipment properly sized for marine and hillside work. Wade and his team hold IICRC certifications and RIA and IFA credentials, and every mold job carries the 90-Day Done Right Promise in writing. If it is not done right, Wade comes back and makes it right, no argument.
Our Mold Remediation Services in Sausalito
Mold Inspection & Testing
In Sausalito, the question is rarely whether moisture is present. It is where it is hiding. We run thermal imaging along uphill foundation walls and below-grade ceilings, take air and surface samples where the bay humidity has kept things damp longer than anyone realized, and give you a straight answer about what needs to happen and what can wait. Floating-home inspections include checking hull liners and below-deck cavities where salt air has been quietly corroding fasteners and feeding mold for years.
Mold Removal
Removing mold means removing the source too. On a Sausalito hillside home, that often means cutting back the uphill drainage that channels storm runoff straight into the foundation, then treating the affected framing and replacing the drywall with materials that can breathe. On a floating home at Waldo Point, removal means sealed containment because the ambient bay air never stops introducing new spores. We use HEPA air scrubbers and negative air pressure on every job, and we do not just spray and walk away.
Black Mold Remediation
Black mold, or Stachybotrys, thrives in the chronic dampness that Sausalito’s bay-and-fog climate produces. We treat it with full containment, negative air, and antimicrobial application that actually reaches the root of the material, not just the surface. Then we document everything with photos and moisture readings so your insurance adjuster sees exactly what we saw. If the adjuster has questions, Wade talks to them directly. You are not relaying information between two parties.
Air Quality Restoration
After remediation, the air inside a Sausalito home needs to be brought back to something a human should breathe. We run high-capacity HEPA scrubbers and desiccant dehumidifiers that pull moisture down to below 50% RH, then verify with measurements you can see. For floating homes, this step matters even more because the marine environment outside the wall never stops pushing moisture back in. The sealing and equipment staging have to be done right or the mold returns in a month.

When you hire us, you are hiring the people who own the gear, know how it behaves in marine humidity, and can have it running within the hour.
Common Mold Remediation Problems We See in Sausalito Homes
- Floating-home moisture that standard dehumidifiers cannot touch. At Waldo Point Harbor, we have seen homeowners run residential-grade dehumidifiers for weeks while relative humidity stays locked at 80% because bay air keeps flowing in. Without a sealed enclosure and a marine-rated desiccant unit, the machine cycles endlessly and the mold keeps growing behind the bulkhead.
- Mold re-colonizing on hillside post-and-pier foundations. Treating visible mold under a Sausalito hillside home without diverting uphill runoff is a temporary fix. The water keeps coming, the framing stays damp, and the mold returns within weeks. We address drainage first, then remediate.
- Salt corrosion accelerating mold growth on hidden surfaces. The marine air off Richardson Bay corrodes drywall screws, framing connectors, and HVAC components years faster than inland homes. Where fasteners rust, moisture wicks in, and mold follows. We check for corrosion-driven moisture intrusion as a root cause, not an afterthought.
- Overloading weight-rated gangways with drying equipment. Floating-home docks have weight limits. Standard restoration trailers and oversized dehumidifiers do not belong on a gangway at Waldo Point without checking load ratings. We stage equipment small, anchor enclosures to structural deck beams, and never risk the walkway or the crew.
Pricing for Mold Remediation in Sausalito, CA
A typical mold remediation job in Sausalito runs $1,800 to $6,500 for a contained room or crawl space. Whole-home remediation on a hillside property with multiple affected areas usually falls between $5,000 and $15,000. Floating-home jobs at Waldo Point and surrounding marinas typically run $8,000 to $20,000 because they require marine-rated desiccant enclosures, stainless hardware replacement, and staging across weight-limited gangways. Mold inspection and testing alone typically runs $350 to $800 depending on sample count and whether thermal imaging is included.
Several factors move the number: how far the mold has traveled, whether structural framing needs replacement, whether asbestos-containing siding from older Sausalito homes complicates the scope, and whether the property is a floating home with marine enclosure requirements. Wade gives you a written scope before work starts, so there is no mystery number at the end. Estimates are free. Call (855) 915-0646 and have Wade walk the property with you.

FAQs - Mold Remediation in Sausalito
On a floating home, remediation requires a marine-rated desiccant dehumidifier inside a fully sealed enclosure anchored to the deck’s structural beams, because open-water air continuously reintroduces moisture. A land-based Sausalito house typically needs source control, HEPA containment, and standard drying equipment sized for the affected area. Floating-home jobs at Waldo Point Harbor also require staging equipment across weight-rated gangways, which limits machine size.
We cut out the affected drywall, treat the framing, and look hard at where the water came from, because old single-pane wood windows and hillside runoff are usually the culprits. Then we dry to below 50% RH with sealed containment so the fog and bay air do not undo the work overnight. Wade documents the moisture readings daily and hands you the log at the end.
Not always. If you can see the mold and smell it, testing mostly adds cost. But if you are selling a floating home or a hillside house with a history of water intrusion, testing gives you a baseline for the insurance adjuster. Wade will tell you honestly whether a test is worth it on your property. Call (855) 915-0646 and ask him directly.
The salt air and near-daily fog corrode springs, hinges, rollers, tracks, and opener chains years faster than they would inland. Rust holds moisture, moisture feeds mold, and the metal degrades further. We replace affected hardware with galvanized or stainless components and advise on corrosion-resistant options where the marine exposure is worst.
Because the uphill runoff was never diverted. If water keeps flowing against the uphill foundation wall, the crawl space stays damp no matter how much antimicrobial you spray. Proper remediation on post-and-pier hillside foundations starts with drainage correction, then encapsulation, then drying to target RH. We do all three and document every reading.
