Ontario Water Restoration Pros provides professional mold remediation & containment in Ontario, CA for residential and commercial properties across the Inland Empire. Remediation in an occupied building is mostly a containment problem. The removal itself is straightforward. Doing it while the rest of the floor ships orders, serves customers or houses tenants is what separates a clean job from a complaint.
Hard containment goes up first: stud-and-poly barriers or zip walls sealed to the deck rather than the ceiling grid, negative pressure held with HEPA-filtered air scrubbers, and a decontamination chamber at the entry. Air leaves the work area through the machine and nowhere else. In a tenant suite that also means sealing the return-air path, because a shared rooftop unit will move spores to every space on the same zone.
What comes out is decided by material, not by appearance. Gypsum, batt insulation, ceiling tile and casework substrate are removed past the visible growth line. Framing, concrete and steel are HEPA-vacuumed, wire-brushed or abrasively cleaned, then wiped. We do not fog a wall and call it done, and we do not paint an encapsulant over growth that has not been removed. Both are shortcuts that come back.
The reason it recurs is almost never the mold. It is the water source nobody closed: a chronic roof drain seep, a condensate pan overflowing on a rooftop unit, a wall that gets wet every time an irrigation head fires against it. We will not schedule remediation until the source is identified, even if that means the job waits a week for a plumber or a roofer.
Scheduling is negotiable and we treat it that way. Demolition and HEPA vacuuming can run after your last shift with the containment left standing overnight, so the space is under negative pressure the entire time and your people walk into a sealed wall in the morning rather than an open one. Nobody has to work beside an open cavity.
With 15+ years of experience, our licensed and insured team brings the right materials and equipment to every job — desiccant dehumidifiers for large open volumes, low-grain refrigerant dehumidifiers, HEPA-filtered negative air machines, 6-mil poly critical barriers and hard containment, ASTM F2170 in-situ concrete relative-humidity probes, penetrating and non-penetrating moisture meters — and backs the work with a written workmanship warranty. We serve Ontario and nearby communities including Chino, Chino Hills, Montclair, Upland.

Materials, equipment and how we do mold remediation & containment
The difference between mold remediation & containment that lasts and mold remediation & containment that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with desiccant dehumidifiers for large open volumes, low-grain refrigerant dehumidifiers, HEPA-filtered negative air machines, 6-mil poly critical barriers and hard containment, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Ontario job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. 15+ years of water damage work in the Inland Empire means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.
