Water damage restoration in Ontario typically costs between $450 and $3,200 depending on the scope, and in most cases our IICRC-certified team can be on-site within 90 minutes. We know Ontario’s housing stock because we’ve worked it for years: the 1950s tract homes south of Holt Boulevard, the newer subdivisions north of the 10, and everything in between. If water is spreading through your slab foundation or through a wind-damaged roof, call us at (833) 589-7005 right now. We’ll assess the damage, start mitigation, and walk you through the insurance documentation from day one.
Why OC Restoration Co Is Ontario’s Preferred Water Damage Restoration Company
Ontario homeowners call us because we understand what their houses actually do when water gets in. That’s not something you get from a general contractor who shows up with a shop vac. Allen Burkhart built OC Restoration Co around a simple principle: document every moisture reading, follow IICRC protocol on every job, and use equipment that actually removes water from framing, not just from carpet. Homeowners who’ve dealt with us after a Santa Ana wind event or a midnight slab leak tell their neighbors. That’s how our reputation in Ontario has grown.
We’re also members of the Restoration Industry Association and IFA, which means we’re held to a professional code of ethics and ongoing education standards, not just our own habits. For insurance adjusters working claims in Ontario, that matters: we produce drying logs, photo documentation, and clear scopes of work that hold up in review. For homeowners, it means you’re not the guinea pig for someone figuring it out as they go.
Restoration work we handle
Water Extraction in Ontario
Water Extraction in Ontario is the first step when water is standing in a home after a supply line burst, a slab leak migration, or a monsoon microburst that overwhelmed a patio drain. It involves more than removing visible water; it means pulling moisture from carpet pad, subfloor, and wall cavities before mold gets a toehold. In Ontario’s stock of slab-on-grade ranches, extraction often reveals water that traveled well beyond the visible stain, moving under vinyl plank and into baseboards that look dry on the surface. A typical water extraction job in Ontario runs $400 to $1,100 depending on affected square footage and how far the water has wicked.
Extraction Before Drying
We run XPOWER air movers and Dri-Eaz refrigerant dehumidifiers on most Ontario extraction jobs. Extraction comes first and must be thorough; drying equipment can’t make up for water left pooling under a vanity or in a wall cavity. Our techs map moisture with meters before we declare extraction complete, and we document those readings for your carrier.
Slab Leak Extraction Challenges
In Ontario’s 1960s and 1970s tract homes, water from a copper pinhole leak under the slab rarely pools where you’d see it. It travels along the vapor barrier and wicks up through flooring and drywall. Extraction in those cases means removing water we’ve located with thermal imaging and moisture mapping, not just responding to what’s visibly wet. That diagnostic step is why our extraction jobs in Ontario often catch damage a general contractor would miss entirely.
Emergency Water Removal in Ontario
Emergency Water Removal in Ontario happens when a water heater catastrophically fails, a washing machine supply hose lets go while you’re at work, or a wind-damaged roof opens up during a Santa Ana-driven rain event. This is the call where speed genuinely matters: in Ontario’s dry heat, mold can colonize wet drywall within 24 to 48 hours, which means the window for simple cleanup is short. Emergency water removal in Ontario typically costs $600 to $2,400 depending on the number of affected rooms and whether structural drying is required immediately after extraction.
Same-Night Mitigation
We answer the phone at 2 a.m. because water doesn’t wait for business hours. Our emergency response to Ontario includes extraction, containment setup, and placement of drying equipment on the first visit. We’re not just dropping off fans; we’re setting a documented drying plan before we leave.
When Board-Up Meets Drying
After a severe wind event in Ontario, we sometimes arrive to find both a wet interior and a compromised roof. That means temporary tarping or board-up alongside water removal, which gets coordinated by the same crew. Other firms make you call a roofer and then wait. We handle the mitigation envelope on one work order.
Trusted Brands We Service in Ontario
We stock and service the equipment lines Ontario homeowners and adjusters recognize: Dri-Eaz for refrigerant dehumidification, Phoenix for high-capacity axial drying, and XPOWER for aggressive air movement. We don’t use consumer-grade fans or rental-store dehumidifiers. When we respond to a water event in Ontario, we arrive with the same commercial drying platforms that national restoration firms run on large commercial losses. That’s the standard we bring to a 900-square-foot tract house off Euclid Avenue, and it’s the standard the job actually needs when water is inside a wall cavity or under slab flooring, not just on the surface.

AfterCommon Water Damage Restoration Problems We See in Ontario Homes
- Wind-driven roof intrusion that hides until it rains. After a Santa Ana event, lifted shingle tabs and missing ridge caps on original 1960s composition roofs let water into the attic weeks before anyone sees a ceiling stain. By the time paint blisters, decking is already wet.
- Copper pinhole slab leaks that never pool. Cold winter nights in Ontario cause original copper supply lines to expand and contract, eventually forming pinholes. The water migrates under flooring, wicks into baseboards, and is always blamed on a roof until moisture mapping says otherwise.
- Attic moisture buildup from wind-driven dust and debris. Santa Ana winds push fine dust through aging attic vents, and that dust holds moisture against framing. Airflow slows, humidity climbs, and mold starts in the attic while the living space below looks completely dry.
- Monsoon microburst flash water that overwhelms peripheral drainage. Ontario’s rare but intense summer downpours can drop an inch of rain in 20 minutes. Older patio covers and flat-roof additions from the 1970s and 1980s simply can’t shed that volume, so water comes in through walls and door thresholds.
Pricing for Water Damage Restoration in Ontario, CA
Let’s be straight about what Ontario jobs actually cost. Water extraction on a single affected room runs $400 to $800. Emergency water removal with structural drying across two or three rooms lands between $1,200 and $2,400. A full slab-leak response with containment, anti-microbial treatment, drying logs, and reconstruction coordination can hit $2,800 to $3,200 before any rebuild work begins. What drives cost in Ontario is the housing stock: slab leaks require detection and mapping, wind-driven roof intrusion means drying attic framing plus interior ceilings, and 1970s-era homes often need more drywall removal than newer builds. We give a written scope before any work starts, and estimates are free. Call (833) 589-7005.

FAQs About Water Damage Restoration in Ontario
You can’t know from the ground, and that’s the honest answer. What looks like a simple roof leak is often a lifted ridge cap or missing shingle tab from wind, but Ontario’s slab homes frequently have a second, hidden source: a copper pinhole leak under the slab. We use moisture mapping and thermal imaging to identify every wet path before we recommend a fix. Call (833) 589-7005 and we’ll tell you what’s actually feeding the stain.
Because the original Type M copper supply lines installed in Ontario’s 1950s-70s tract homes have thinner walls than modern code requires, and decades of thermal expansion on cold Inland Empire nights eventually wears pinholes through them. The water travels under the slab and wicks up through flooring and drywall, so you won’t see pooling. By the time baseboards swell, the leak has usually been active for weeks. Call us for a moisture assessment before you assume it’s a roof issue.
Often yes, especially when we’re on-site within 24 hours. Our Injectidry structural drying system pulls moisture from inside wall cavities without removing drywall, which preserves more of your original material. The limit is contamination: if floodwater carried silt or sewage, affected drywall comes out, no negotiation. We’ll know the difference quickly. Call (833) 589-7005 to get a scope of work.
Within 24 to 48 hours, even in Ontario’s low ambient humidity. The inside of a wet wall cavity creates its own microclimate, and once mold spores germinate, every hour of delay expands the remediation scope and the insurance paperwork. You don’t want to test the 48-hour limit. If you’ve had water intrusion, call us the same day at (833) 589-7005, not after the weekend.
We run Dri-Eaz refrigerant dehumidifiers, Phoenix axial air movers, and XPOWER air movers, plus Injectidry for targeted structural drying. These are the same platforms national restoration firms use on large losses. We don’t use rental-store fans, and we document the drying environment with daily readings that your adjuster can review line by line. Estimates are free: call (833) 589-7005.
