Fast, Reliable Mold Remediation Across Davis
Mold remediation in Davis typically runs $1,800-$6,500 depending on how far moisture has traveled and how many wall cavities are involved. Most jobs we handle in Davis are completed within 3 to 7 days, and we answer the phone with a live dispatcher around the clock. If you’ve found mold in a home off Russell Boulevard, a rental near campus, or a 1950s tract house in North Davis, call (888) 737-2439 and we’ll have a certified crew at your door, usually the same day you call.
Davis has a mold problem that most homeowners don’t see until it’s well established. The winter tule fog that settles over the Sacramento Valley keeps outdoor humidity near 100% for weeks at a time, and the city’s clay-heavy soil holds water against slab foundations with nowhere to drain. When you add forty-year-old supply lines and single-pane windows to that equation, the result is predictable: moisture gets in, it doesn’t dry out, and mold follows. We know this because we’ve been pulling wet drywall out of Davis homes for years, and we’ve learned exactly where the water hides here.
Why Floodline Restoration Co. of California Is Davis’s Preferred Mold Remediation Company
Floodline Restoration Co. of California was founded in 2010 by Curt Bowman, built around a dispatch board rather than a sales desk. That matters in Davis, where mold jobs tend to surface all at once: a tenant gives notice, a landlord finally opens the wall, and suddenly there’s a remediation deadline tied to the next move-in date. We answer the phone at 2 a.m. with a live person because that’s when Davis landlords and property managers are making decisions about a unit that has to be ready in ten days. Curt built the company so the person who takes your call can send a truck. No phone tree, no recording, no waiting for a sales rep to call back.
Our crews working in Davis are background-checked, uniformed, and trained to IICRC and RIA standards. We carry Dri-Eaz dehumidifiers, Phoenix air movers, XPOWER air scrubbers, and Injectidry drying systems that let us dry wall cavities without tearing out every square foot of drywall. More important than the equipment: we’ve worked enough units west of the UC Davis core to know what a patched-over tenant water event looks like, and we’d rather show you the thermal imaging than tell you it’s fine. That’s the honest way to do it, and it’s why Davis property owners keep calling us back. Every job is backed by the 90-Day Done Right Promise, in writing, with no argument if something isn’t right. We stand behind it.
Our Mold Remediation Services in Davis
Mold Inspection & Testing
Mold inspection in Davis costs $250-$450 for a visual assessment with moisture mapping, and $400-$750 if you add air sampling and lab analysis. In Davis’s older apartment stock near campus, we recommend thermal imaging on any unit with a history of tenant turnover, because the moisture that feeds mold is often sealed behind fresh paint and drywall patches. Our inspectors use moisture meters and infrared cameras to find the water source first, because treating mold without stopping the water is just rescheduling the problem.
For landlords with multiple units in ZIP 95616, we can inspect several apartments in one visit and provide a written Scott scope of work for each unit, with photo documentation your insurance carrier can use without a fight. That’s the Keystone Standard: you see what we see, and you get it on paper.

Mold Removal
Mold removal in Davis averages $1,200-$4,500 for contained remediation of a single room or wall cavity. The number that matters most in Davis is how many layers of old water damage are hiding behind the visible mold. A 1970s apartment near downtown that’s cycled students for twenty years might have three separate moisture events stacked in one wall, each cosmetically patched by a previous owner. When our crew opens that wall, the job scope changes from surface cleaning to full cavity removal, and we’ll show you exactly what we found before we start tearing out more.
We set containment with negative air pressure, remove affected drywall and insulation, treat the framing with antimicrobial agents, and dry the cavity to the IICRC dry standard before rebuilding. We log daily moisture readings and hand you the log. Done right, and backed in writing.

Black Mold Remediation
Black mold remediation in Davis runs $2,500-$8,000 for typical single-family homes and $1,800-$5,000 per apartment unit, depending on the square footage of affected drywall. The cost is higher in Davis than in some neighboring cities because so much of the housing stock here is slab-on-grade, which means the water that fed the mold often wicked up through flooring and baseboards before anyone saw the colony on the wall. That’s not surface mold. That’s a moisture event that moved laterally under the slab, and it requires full containment, not just scrubbing.
If you see black staining around baseboards, windows, or under sink cabinets in a Davis home, call us. If you smell a musty odor that comes and goes with the winter fog, call us too. We don’t scare people into work they don’t need, but we also won’t tell you a quick bleach wipe is enough when thermal imaging says otherwise. Call (888) 737-2439 and we’ll tell you straight what you’re dealing with.

Air Quality Restoration
Air quality restoration in Davis typically costs $600-$1,800 and follows any mold remediation where spores have spread through the HVAC system or settled into carpet and upholstery. Davis winters make this worse than people expect: when the tule fog rolls in, windows stay closed, heating systems circulate air continuously, and a mold colony in one room becomes a spore problem throughout the whole house. We run HEPA air scrubbers during remediation to capture airborne spores at the source, then clean ductwork and replace filters before we hand the keys back.
For Davis households with allergy or asthma concerns, we recommend air sampling before and after remediation so you have lab data showing the spore count dropped. Your insurance carrier gets the before-and-after, and you get a house you can breathe in.

Common Mold Remediation Problems We See in Davis Homes
Every city has its own mold patterns. In Davis, the problems are tied to the age of the housing stock, the density of student rentals, and a climate that keeps things damp all winter. Here’s what we see most often:
- Layered moisture in student rental walls: Units near UC Davis that cycle tenants every year or two almost always have old water events patched with drywall compound and paint rather than properly dried. Our thermal imaging routinely shows three or four distinct moisture strata in the same wall cavity, one from each previous decade. Surface treatment won’t fix that; full cavity remediation will.
- Lateral moisture under slab floors: Davis sits on flat terrain with clay-heavy soil and no natural drainage gradient. When water pools against a foundation during an atmospheric river storm, it doesn’t run off, it soaks through the slab. That moisture wicks into baseboards and wall cavities weeks or months later, long after the visible leak is forgotten.
- Winter fog mold blooms: The Sacramento Valley’s dense ground fog keeps outdoor relative humidity at or near 100% for weeks in December and January. In older Davis homes with single-pane windows and poor ventilation, that fog alone can push indoor humidity above 60%, which is enough to feed dormant mold spores that never needed a leak to start growing.
- Rotting crawl space framing: Homes in Davis with crawl spaces, especially in the 95617 and 95618 ZIP codes, often have inadequate vapor barriers and venting that doesn’t match the reality of fog-season humidity. We regularly find floor joists and rim boards with mold and rot that the homeowner never saw because nobody goes under the house in winter.
Pricing for Mold Remediation in Davis, CA
Mold remediation in Davis runs $1,800-$6,500 for most jobs. A small bathroom mold problem might come in at $1,200; a full wall-cavity removal with containment in a 1960s fourplex usually lands around $3,500-$5,000. What moves the price in Davis isn’t the labor, it’s how far the water traveled before anyone looked. Slab-on-grade construction means moisture migrates laterally under flooring, and in Davis’s clay soil, that migration can cover twenty feet or more before it shows up as mold on a baseboard.
Here’s what you can expect for typical Davis mold work:
- Mold inspection with thermal imaging: $250-$450
- Mold inspection with air sampling: $400-$750
- Contained mold removal, single room: $1,200-$2,800
- Full cavity remediation, apartment unit: $3,000-$5,500
- Air quality restoration: $600-$1,800
- Crawl space treatment with vapor barrier: $1,500-$4,000

FAQs - Mold Remediation in Davis
Older apartments near UC Davis need full cavity removal because decades of student turnover means water events get patched over rather than properly dried. Each time a tenant leaves, landlords do cosmetic work: new paint, drywall mud, maybe a new sink trap. But the moisture behind that drywall never dried. After two or three cycles of this, the wall cavity holds multiple layers of damp, moldy material. Surface cleaning can’t reach it, and it will bloom through the new paint within a year. In a 1960s fourplex off Russell Boulevard, our crew used a Dri-Eaz dehumidifier and Phoenix air mover after a tenant-reported ceiling stain revealed layered moisture behind drywall from three previous leaks. Full cavity remediation was the only option. Call (888) 737-2439 and we’ll assess what’s actually inside your walls.
We handle tight-clearance work in Davis by sizing equipment and containment to the space, not the other way around. Many of the rental units and townhomes near downtown Davis have alley-load doors, narrow stairwells, and no room to stage full-size drying equipment. Our crews are trained to set up negative-air containment in compact floor plans, run Injectidry drying mats under cabinets and behind baseboards, and position air movers so they don’t block doorways or fire exits. If a unit has a single shared entry, we schedule work around tenant access windows and post proper IICRC-required signage. But access constraints can delay dry-out and let mold spread, so the faster we get in, the less drywall we have to remove.
Yes. Davis sits in the Sacramento Valley’s tule fog belt, with dense ground fog that keeps relative humidity near 100% for weeks each winter. That sustained humidity can push indoor moisture levels high enough to feed dormant mold spores even in a house with no active plumbing leak. Older homes with single-pane windows and no bathroom or kitchen exhaust fans are the most vulnerable. If you notice a musty smell in early winter that fades by June, that fog-driven humidity is likely reaching hidden mold. A dehumidifier helps, but if mold is already established in a wall cavity or crawl space, you need remediation, not just humidity control. Call us for an inspection and we’ll give you a straight answer.
When water moves under slab floors in Davis, it travels laterally through the clay and wicks up through flooring, baseboards, and wall plates. Davis’s pan-flat terrain and clay-heavy soils provide essentially no natural drainage, so winter storm water pools against foundations and soaks through the slab. What you see is buckling laminate or a moldy baseboard; what’s underneath is moisture that may extend ten or twenty feet from the original intrusion point. Surface mold removal won’t stop it because the moisture is coming from below. We use thermal imaging to map the full moisture plume, then dry or replace the affected flooring and treat the slab before rebuilding. Call (888) 737-2439 and we’ll map it accurately.
Yes. A substantial portion of our mold work in Davis, particularly in ZIP 95616 near the UC Davis campus, is for landlords, property managers, and cooperative housing boards. We know the constraints: tenants have to move in on a specific date, unit access is limited, and the insurance adjuster wants documentation that justifies the scope. We schedule remediation around lease timelines, work in tight access windows, and provide photo documentation, moisture logs, and a written scope your adjuster can approve without a back-and-forth. We typically bill the carrier directly, so property owners don’t have to front the full cost. If you manage multiple Davis units, call (888) 737-2439 and ask about multi-unit inspection pricing.
