Mold Remediation Services in Corona, CA
Mold removal and remediation in Corona, CA, from Grand Boulevard homes to South Corona slab leaks. One team fixes the leak and removes the mold. Open 24/7.
Corona's oldest homes sit in and around Grand Boulevard, the circular road laid out during the city's citrus-era founding in the 1880s. Most of the rest of the city was built from the late 1970s on, with South Corona, Eagle Glen and Dos Lagos filling in through the 2000s. That range of ages means mold here can come from century-old drain lines, 1980s pipe past its prime, or a slab leak in a 20-year-old house.
We look at the house before deciding how to treat it. Our plumbers locate and repair the moisture source, and our IICRC-certified restoration techs contain the area, remove what mold has grown into and dry the structure. The leak and the mold get handled together instead of being passed between two contractors.

What's different about mold remediation in Corona
Polybutylene and aging copper in 1980s tracts
Some homes built from the late 1970s through the early 1990s were plumbed with polybutylene, a gray flexible plastic often stamped PB2110. Others have aging copper under the slab. Either one can fail behind a wall or under a floor, and a leak that runs unnoticed gives mold weeks of head start.
Slab leaks across the city
Slab-on-grade homes are the norm in much of Corona. A leak under the concrete can push water up into carpet pad, tack strip and the bottom of the drywall. If a floor feels warm in one spot or your water bill jumped, our guide to the signs of a slab leak is a good place to start.
Hillside runoff in Sierra del Oro and Eagle Glen
Homes on and below slopes can take on runoff during heavy winter storms. That water carries soil and contaminants, so it's handled as dirty water, and soaked porous materials usually come out instead of being dried in place.
Older homes inside the circle
Galvanized lines, cast iron drains and clay sewer laterals under mature trees are common near Grand Boulevard. A root-blocked lateral can back up into a tub or floor drain, and sewage-soaked flooring is a mold problem and a sanitation problem at once.
Signs it's time to call
- A warm patch on the floor, or running water heard with fixtures off
- Dark staining along the bottom of the drywall in a slab home
- Gray plastic supply pipe stamped PB2110 near the water heater
- Muddy water marks along a wall that faces a slope
- A musty odor that lingers after a drain backup in an older home
How we handle it in Corona
Every job starts with the water source - a slab line, a failed polybutylene fitting, a sewer lateral or a drainage problem. Then we map moisture and set up containment based on the size of the area. The EPA says homeowners can usually handle mold covering less than about 10 square feet themselves. Beyond that, or when the water was dirty or the growth is hidden, professional remediation with HEPA filtration and proper removal is the safer route.
We inspect and give you an up-front quote before work begins. National cost guides such as This Old House and Angi put typical professional mold remediation at roughly $1,200 to $3,750, though your price depends on size, location and rebuild needs. We document the damage and can work with your adjuster, but whether mold is covered depends on your policy. Read more about our mold remediation service or our Corona service area.
Corona questions, answered
I found polybutylene pipe in my Corona home. Should I check for mold?+
If it has leaked before, or you notice musty odors or stains near where it runs, yes. We can take moisture readings on walls and ceilings along those lines. If anything is wet, we fix the leak and remove any mold, and we can talk through repiping so it doesn't happen again.
Mud washed off the slope behind my house into a bedroom. What should I do?+
Avoid touching the water, take photos for your insurer and call us. Runoff is contaminated, so carpet pad and drywall it soaked usually need to be removed. The faster drying starts, the less chance mold has to take hold in the framing.
Do you cover all of Corona?+
Yes, from the neighborhoods around Grand Boulevard to Sierra del Oro, Corona Hills, South Corona, Eagle Glen and Dos Lagos. Someone picks up at any hour, and for urgent leaks we typically reach Corona in 1-2 hours, depending on where you are and how many calls we're handling.
