Mold remediation in Davis typically costs between $1,200 and $4,800 depending on the square footage affected and whether the source is a simple supply line leak or capillary moisture wicking through a slab. Most jobs in a home this size run between $1,800 and $3,200, and you’ll see the written number before we start. We know Davis homes: the 1950s-70s slab-on-grade builds near Central Davis, the wood-framed ranches along Covell Boulevard, the newer apartment stock near UC Davis. Our crews reach most Davis neighborhoods within 45 to 60 minutes of your call. For a free estimate, call (279) 277-2396.
Why Tidemark Water Damage Sacramento Is Davis’s Preferred Mold Remediation Company
We’re independently owned and operated, working to the Cedarwell Care Promise, and Rick Sumner has built the team around one non-negotiable standard: a written price before anyone picks up a tool. Davis homeowners call us because our technicians are IICRC-, RIA-, and IFA-credentialed and arrive with shoe covers and drop cloths already loaded on the truck. Floors and furnishings get protected as a standard step, not an upsell.
Local knowledge matters here. Davis has strict water conservation ordinances and LEED-oriented building codes. That means post-remediation rebuilds often require water-efficient fixtures and specific permitting. We’ve worked through those requirements dozens of times. We document every job with photos before the crew leaves, so you see exactly what was done and how the space was left. Every job also carries the 365-Day Done Right Promise: if the remediation isn’t done right, we make it right.
Dispatch and scheduling are coordinated from our Sacramento office. Crews serve Davis locally, and a live person answers the phone 24/7. No voicemail queues, no callback delays.
Restoration work we handle






Mold Remediation Services in Davis
Mold Remediation Services in Davis start with finding how moisture got there in the first place. We use moisture mapping and readings to trace the water source, then build a written scope of work before any equipment comes through the door. A typical remediation in a Davis single-family home runs $1,800 to $3,200, with larger crawl space jobs reaching $4,500 or more.
Containment and Source Removal
We set up negative air containment in the affected area so spores don’t move into adjoining rooms. In older wood-framed homes with shared walls, this step matters more. Skipping it allows mold to spread during structural drying.

Antimicrobial Treatment and Structural Drying
After removing affected materials, we apply antimicrobial treatment to the substrate and run professional-grade drying equipment. Dri-Eaz dehumidifiers and Phoenix air movers pull moisture out of framing, slab, and drywall until readings confirm the space is stable.

Professional Mold Removal in Davis
Professional Mold Removal in Davis means removing the mold, not painting over it. If visible growth covers more than 10 square feet, or if the source is under-slab moisture, a contractor-grade scope is almost always the right call rather than a surface cleaning. Most Davis jobs in a single-family home run $1,500 to $3,500, including containment, removal, drying, and antimicrobial application.
Slab-On-Grade Specialists
Davis’s older central neighborhoods were developed largely in the 1950s-70s for UC Davis faculty and staff. Many of those homes sit on concrete slabs with original cast-iron drain lines now failing due to expansive clay soils and high groundwater. That’s a recurring mold source we see in Central Davis and along the Covell/Anderson corridor.
Flooring Lifts and Hidden Reservoirs
When moisture wicks up through concrete via capillary action, it lifts vinyl or wood flooring and creates hidden mold reservoirs underneath. We remove the flooring, dry the slab, treat it, and only then discuss reinstallation. You know the price for any new flooring before we order it.
Trusted Brands We Service in Davis
Our crews work with equipment from Dri-Eaz, Phoenix, and XPOWER, the same machines used by leading restoration specialists. We stock common replacement parts and consumables for these systems, which means faster turnaround for Davis jobs. Whether it’s replacing a Dri-Eaz dehumidifier filter or calibrating an XPOWER air mover, our technicians handle it on site rather than sending equipment back to a distributor. That saves days on a typical Davis remediation.

AfterCommon Mold Remediation Problems We See in Davis Homes
- Capillary moisture through slab-on-grade foundations. High water tables near the UC Davis arboretum push moisture up through concrete in spring. Homeowners often mistake lifted vinyl or warped wood for a plumbing leak, when the real source is groundwater.
- Failed cast-iron drain lines under older homes. Expansive clay soils shift and crack original cast-iron pipes in 1950s-70s builds. The resulting slow sewer backups create persistent mold behind walls and under flooring in Central Davis and West Davis.
- Poor drainage along old creek beds and low-lying areas. Flat terrain and clay-heavy soils mean winter storms in the Covell/Anderson corridor and near old creek beds can leave standing water against foundations. That water migrates into wall cavities within days.
- High-turnover student apartments near campus. Shared walls and balconies in newer multi-story complexes create moisture issues that get ignored between tenants. Mold spreads through common wall cavities before anyone reports it, requiring containment across multiple units.

A typical mold remediation in Davis runs $1,800 to $3,200 for a single-room job with containment, removal, drying, and antimicrobial treatment.

FAQs About Mold Remediation in Davis
Expansive clay soils in Davis crack and shift cast-iron drain lines under older slab foundations, which creates slow sewer backups that feed mold behind walls and under flooring. Clay soil also holds water against the slab edge after winter storms, which migrates into wall cavities and creates the conditions mold needs. The fix is to address the moisture source first, not just the visible mold.
Our scope includes source identification with moisture mapping, containment setup, removal of affected materials, structural drying with professional-grade equipment, antimicrobial application, and a photo of the clean-up before the crew leaves. You get the written scope and price before we start. For Category 2 water damage, which carries contaminated water from sources like drain backups, we also document every step for your insurance adjuster.
Yes. Davis enforces water conservation ordinances and LEED-oriented building codes that impact rebuilds and replacements after remediation. If a bathroom or kitchen needs reconstruction, we coordinate with local permitting requirements for water-efficient fixtures and materials. We’re familiar with these codes and include them in the written scope, so you don’t get a surprise permit violation later.
Older and even newer apartment complexes near campus have shared walls and common ventilation spaces. Without negative air containment, mold spores released during removal can spread into adjoining units within hours. We always set up containment and run HEPA air scrubbing during remediation in multi-unit buildings. This protects your neighbors and prevents a building-wide problem.
Mold can start growing within 24 to 48 hours of a leak, and in Davis’s clay-heavy soil, water that sits against a foundation wicks into walls faster than most homeowners expect. Call us at (279) 277-2396 within the first day or two and we can often contain the problem before it spreads past one room. The longer moisture sits, the larger the affected area and the higher the remediation cost.
If you suspect mold in your Davis home, call (279) 277-2396. We’ll walk you through what’s happening, what it will cost, and what we’ll protect before any work begins. Rick Sumner and our Davis crews are ready whenever you need us.
