Mold Remediation and Removal in Fontana
Mold remediation in Fontana, CA for post-war homes, sewer backups and wind-damaged roofs. We repair the plumbing and remove the mold. 24/7 emergency service.
A lot of Fontana's housing dates from the decades after Kaiser Steel opened its mill in 1942. Those modest single-story homes in central and south Fontana are now 60 to 80 years old, with galvanized or early copper supply lines, cast iron drains and clay sewer laterals. When mold turns up in one of them, a tired pipe is usually somewhere nearby.
Fontana also sits below the Cajon Pass, in the path of some of the strongest Santa Ana winds in the region, and a roof damaged in a windstorm often doesn't leak until the next rain. So mold here can start overhead in the attic just as easily as under a sink. Our plumbers fix the cause, and our IICRC-certified restoration techs take care of the mold and the drying.

What's different about mold remediation in Fontana
Post-war galvanized and cast iron
Galvanized pipe corrodes from the inside, and older cast iron drains crack with age. Both tend to leak slowly inside walls and under floors. A cracked drain under a bathroom or kitchen can keep the floor and wall bottoms damp, and because it's drain water, it's dirtier than a clean supply leak.
Sewer backups from old laterals
Roots and cracks in clay sewer laterals can push sewage back into tubs, showers and floor drains. Sewage is contaminated water. The EPA recommends professional cleanup, and porous materials it soaks - carpet, pad, the bottom of the drywall - usually need to be removed and the area sanitized.
Roof leaks after Santa Ana winds
Wind can lift or tear off shingles without anyone noticing from the ground. When rain finally comes, water soaks the roof deck, attic insulation and ceiling drywall. Insulation that stays wet in a closed attic is a strong candidate for mold, which is why emergency tarping right after a windstorm matters.
Slab leaks in Sierra Lakes and Southridge
Sierra Lakes, Southridge Village and other later communities are mostly slab homes with copper or PEX. A leak under the slab can quietly wet flooring and baseboards across a whole room.
Signs it's time to call
- Ceiling stains that appear only after the first rain of the season
- A sewer smell mixed with a musty odor near a bathroom or laundry
- Darkened, matted attic insulation or a water-stained roof deck
- Cracked or swollen flooring near a tub or toilet in an older home
- Paint bubbling along the bottom of a wall that shares a drain line
How we handle it in Fontana
We fix whatever let the water in, whether that's a cast iron drain, a sewer lateral, a supply line or a roof that needs a tarp until it can be repaired. Then we map moisture, contain the work area and remove what mold has grown into. Sewage-affected areas are sanitized as well as cleaned. HEPA vacuums and air scrubbers capture spores stirred up during removal, and drying equipment stays until readings confirm the materials are dry.
Take photos of the damage, and of the roof if wind was involved, before anything is thrown away. We add our own photos, moisture readings and a written scope, and we can work with your adjuster. Mold coverage depends on your policy and the cause, so we don't promise approval. See our Fontana restoration page and our guide to mold remediation vs. mold removal.
Fontana questions, answered
Wind damaged my roof and now the attic smells musty. Is that mold?+
It may be. Once insulation and roof decking get wet and stay wet, mold can start within 24 to 48 hours. We tarp the roof if needed to stop more water, check the attic with moisture meters and remove wet or moldy insulation and drywall.
My sewer backed up in my 1950s Fontana home. Will mold grow?+
It can, and sewage is contaminated water, so it isn't a do-it-yourself cleanup. Our plumbers clear the line and run a camera to find the cause, and our restoration team removes affected materials, sanitizes and dries the area.
How soon should I call after finding a leak in Fontana?+
Right away. The EPA recommends drying water-damaged areas within 24 to 48 hours to prevent mold. We're open 24/7, and emergency arrival is typically within 1-2 hours depending on your location and call volume.
