If you’re smelling musty air or seeing staining on a west-facing wall, call (833) 589-5317. We’ll walk the scope with you before anything gets torn open.

Fontana isn’t a city where mold behaves predictably. The same Cajon Pass wind that shoves rain sideways into stucco in February is the wind that brings 100°F heat two days later. That sequence changes everything about how fast mold colonizes and where it hides. Our crews work in these homes every week, and we know exactly which walls go first.
Why Dry Line Water Damage Is Fontana’s Preferred Mold Remediation Company
We’re an IICRC-certified operation, which means our technicians train to a published third-party standard for mold assessment, containment, removal, and clearance, not an in-house checklist. The certification matters in Fontana because the housing stock here is unforgiving: 1950s and 1960s tract homes with wood-framed stucco walls that hold moisture like a sponge after wind-driven rain. A generalist with a spray bottle and a fogger won’t fix what’s behind the baseboard.
Our crews work throughout Fontana’s older south-side neighborhoods, from the streets off Merrill Avenue to the pockets around Jurupa Avenue and the established blocks near downtown. We know these homes. We know the shallow-pitch roofs. We know the galvanized plumbing in the walls. When a Fontana homeowner calls about a musty smell with no visible leak, we don’t guess. We run moisture mapping and find the intrusion point before we write a scope.
Glen Pacheco leads our team, and his approach is simple: document what’s there, remove what’s affected, dry what remains, and prove it with readings. That’s the whole job. No theater, no upsell.
Because we handle Mold Remediation, water damage, and fire damage under one roof, Fontana property managers and homeowners don’t get shuffled between vendors when a mold issue traces back to a plumbing leak or a roof failure. One crew owns the full loss scope from first assessment to final clearance. That’s how you avoid the finger-pointing that stalls insurance claims.
Documented Process, Not Just Visual Clearance
Every remediation we run in Fontana ends the same way: a set of moisture readings showing the framing is dry, followed by a post-remediation verification that the air inside the containment zone is cleaner than the air outside it. We don’t remove visible mold and call it done. We run the numbers and hand you the log.
Restoration work we handle






Professional Mold Removal in Fontana
Professional Mold Removal in Fontana starts with containment, not demolition. We seal the affected room with negative air pressure so spores don’t get pushed into the rest of the house while we work. Then we remove the affected drywall, insulation, or flooring, bag it inside the containment zone, and HEPA-vacuum every surface before the antimicrobial treatment goes on the framing. A contained removal in a single Fontana room usually runs $1,800 – $3,500, depending on how far into the wall cavity the damage extends.
What Actually Happens During Removal
We set up a containment barrier with a negative air machine exhausting outside through a window. The affected drywall comes out in sections, goes into 6-mil bags, and leaves through the containment path, not your living room. Once the wet or moldy material is out, we wire-brush the framing and apply an antimicrobial to kill anything still present on the wood.
When Removal Beats Surface Treatment
Fontana homeowners sometimes wipe visible growth with bleach and hope that’s the end of it. It rarely is. If you’re seeing mold on a west-facing stucco wall, the visible surface growth is usually the tip. The paper face of the drywall behind the paint is often colonized, and no surface cleaning reaches that. Removal is the only way to stop the recurrence. We don’t do half-scopes on south-side tract homes because we’ve seen what happens six months later.
Mold Inspection in Fontana
Mold Inspection in Fontana means mapping moisture, not just looking at stains. Our techs run thermal imaging and moisture meters across walls, floors, and ceilings to find hidden water that hasn’t shown itself as visible growth yet. A thorough inspection in Fontana typically runs $350 – $600, and we provide photo documentation with annotated readings you can send straight to your adjuster.

What the Inspection Covers
We check the obvious spots: baseboards, sill plates, under sinks, behind the water heater, the garage wall shared with the house. But in Fontana, we also check the non-obvious ones: the top plate where the roof meets the wall, the inside of west-facing stucco on older homes, and any plumbing chase with original galvanized lines. Those are the places Fontana mold starts.
When to Call for an Inspection
If you smell musty air but can’t see water anywhere, call for an inspection before you paint or patch anything. Same if you had a Santa Ana wind event with sideways rain and noticed a watermark on an interior wall weeks later. The inspection costs less than opening the wrong wall.
Trusted Brands We Service in Fontana
We run B-Air air movers and dehumidifiers on Fontana mold jobs, and we use Injectidry panels when we need to dry a wall cavity from the inside without tearing out the whole assembly. These are the same brands large-loss restoration contractors run on commercial jobs. For Fontana homeowners, that means the drying curve on your job isn’t dependent on equipment someone rented from a hardware store. We also stock replacement filters, HEPA bags, and containment supplies locally, so a mid-job restock doesn’t mean a two-day delay waiting on a shipment.

AfterCommon Mold Remediation Problems We See in Fontana Homes
- Wind-driven rain behind stucco with no ceiling stain. Santa Ana winds push water sideways into stucco cracks and roof-edge vents. The water sits in the wall cavity until the smell surfaces, often weeks later, with no visible leak anywhere in the house.
- Post-storm heat accelerating colonization. After the wind event, Fontana often gets 100°F+ days within 48 hours. That heat turns a damp wall cavity into an incubator. Mold that might take a week to establish in a coastal climate is established here in two days.
- Bleach-and-paint “fixes” without containment. Homeowners wipe the visible growth off a wall, paint over the stain, and the hidden cavity source keeps feeding new growth. Without containment during removal, spores get pushed into the rest of the house and the problem spreads.
- Original 1960s plumbing leaks inside wall cavities. South Fontana tract homes often still have galvanized supply lines behind the walls. A pinhole leak can run for months before it shows on the Sheetrock, and by then the mold scope is far bigger than it needed to be.
Pricing for Mold Remediation in Fontana, CA
Small contained removals in Fontana, like a single closet or bathroom wall, typically run $1,800 – $2,800. A full room with cavity drying behind the wall assembly lands around $3,000 – $4,500. Whole-house scopes with multiple affected rooms, pack-outs, and structural drying can run $5,000 – $6,500 or more depending on how far the moisture traveled. What moves the number is how much drywall has to come out and how long the drying equipment has to run. We give you a written scope before work starts, not after.

FAQs About Mold Remediation in Fontana
Santa Ana winds drive rain sideways into walls, not vertically onto roofs. A normal rainstorm hits the shingles and runs to the gutters. A Santa Ana event pushes water directly into stucco cracks, roof-edge vents, and the junction where the wall meets the roof. The water enters the wall cavity from the side, so there’s no ceiling stain and no puddle. The moisture sits inside the wall and mold starts behind the paint. Then the post-wind heat bake finishes the job. If you smelled must after a February wind event, call for a moisture inspection.
Mold can start colonizing within 24 – 48 hours inside a wet Fontana wall cavity, especially in summer or after a heat-spike following a Santa Ana event. The paper face of drywall is a food source, and the 100°F+ air behind the stucco works like an incubator. Act on a musty smell the week it appears, not the month after.
Yes. Galvanized supply lines from that era are prone to pinhole leaks that run inside wall cavities for months before any visible stain appears. A shallow-pitch roof also leaves less attic space to catch wind-driven water before it reaches the ceiling assembly. Homes with both conditions often need a slightly larger removal scope because the moisture has had longer to travel before anyone noticed. We inspect both systems during an assessment and document what we find in the scope of work.
No. Containment stays up regardless of outdoor temperature. The negative air pressure and physical barrier keep spores from spreading into unaffected parts of the house while we remove affected material and dry the framing. Cutting containment short to save time is how recurrence happens, and it’s not a shortcut we take on any Fontana job.
We check moisture levels inside the adjacent wall cavity, along the sill plate, behind the baseboard, and in any plumbing chase nearby. We also check the top plate where the roof meets the wall, especially on west-facing stucco. The goal is to find the moisture source, not just confirm there’s mold. The inspection report includes annotated readings and photos so your adjuster sees the intrusion point and the affected area, not just the stain you called about.
