Fire damage restoration in Ontario moves fast because the Santa Ana winds do. A single wind event in October can lift old tar-and-gravel roof sections on 1960s stucco tracts and push embers into attic vents, producing dozens of smoke-odor, roof-tarp, and water-intrusion calls in one night. Renew Water Damage has served Ontario since 2015 with IICRC-certified crews, commercial-grade drying equipment, and one certified team from extraction through final restoration. Call (833) 620-3891 if you’re standing in a room that smells like smoke and wondering what happens next.
Why Ontario Homes Are Different
Ontario sits at the base of the San Gabriel Mountains where the Inland Empire’s Santa Ana corridor funnels wind through the older residential core north of the 10. Homes in 91762 and 91764 are largely 1950s-to-1970s single-story stucco over wood frame, with low-slope or tar-and-gravel roofs that were never designed for 60-mile-per-hour gusts. When a Santa Ana event tears off a roof section, the damage rarely stops at the roof. Wind-driven rain follows the same path the embers did, soaking attic insulation and running down interior wall cavities behind the stucco. That is why so many Ontario fire jobs turn into water jobs within 48 hours. The industrial warehouse belt along the 10 and 60 corridors is different: those are large commercial losses, often fire suppression water released from sprinkler systems, and they demand the same commercial drying arsenal we run, just at scale. Stucco hides moisture well until it fails visibly, which means the damage we find in Ontario homes is usually older than the homeowner realizes.
Restoration work we handle






Our Main Ontario Services
Ontario homeowners and property managers call us most often for two situations: water that has already moved into walls or subfloors, and mold that appeared after moisture sat too long. Both need certified attention fast.
Water Damage Restoration in Ontario
When a water heater lets go in a 1960s Ontario home or a wind-damaged roof lets rain into the attic, the first 48 hours decide whether you are drying a room or replacing drywall. Our IICRC-certified crews arrive with Dri-Eaz and Phoenix dehumidifiers plus Injectidry wall-cavity drying systems that pull trapped moisture from inside stucco walls without unnecessary demolition. That matters in Ontario because stucco hides water damage until it is well advanced. Water Damage Restoration in Ontario covers extraction, structural drying, and the full rebuild path.

Mold Remediation in Ontario
Ontario’s semi-arid climate does not prevent mold; it concentrates moisture. Long dry spells crack stucco and old roof seams, then sudden winter rain drives water into those gaps where it sits inside wall cavities. Mold follows within days in the warm Inland Empire air. Our remediation follows IICRC S520 protocols with containment, HEPA air scrubbing, and source removal rather than surface spraying. Mold Remediation in Ontario explains the containment and clearance testing process in detail.

Fire Damage Restoration in Ontario
Fire damage in Ontario almost always arrives on the back of a Santa Ana wind event between September and January. The winds drive embers from wildland fires into attic vents and roof gaps, smoke penetrates every porous surface, and the fire department’s water suppression soaks whatever did not burn. Homes in the older ZIPs, 91761, 91762, and 91764, carry the brunt of that exposure. This is a fire, water, and smoke combination that needs one team handling all three. That is exactly how Fire Damage Restoration works at Renew Water Damage: soot and smoke odor removal first, then structural drying, then restoration to a clean, stable surface.
Fire Damage Restoration Company
Signs you need it
Visible soot lines on walls or ceilings, smoke odor that persists after airing out, or charred framing exposed by fire or firefighting water means the damage goes beyond surface cleaning.
What it costs in Ontario
Full-service fire damage restoration in Ontario typically runs between $2,500 and $45,000 depending on square footage, smoke penetration depth, and whether structural framing was compromised.
How we do it
We board up and tarp first, then remove charred materials, run HEPA air scrubbers, clean every surface with alkaline soot-specific agents, and dry the water the fire department left behind.
Smoke Odor Removal
Signs you need it
The smell returns every time the house warms up or the HVAC kicks on, which means smoke particles are lodged in wall cavities, ductwork, or attic insulation rather than on cleanable surfaces.
What it costs in Ontario
Smoke odor removal in Ontario ranges from $1,500 to $8,200, with duct cleaning and attic insulation replacement pushing toward the upper end.
How we do it
We deploy thermal fogging for soft goods, hydroxyl generators for occupied spaces, and targeted media blasting on studs and subfloors, followed by sealing to lock in any residual odor.
Fire Damage Cleanup
Signs you need it
Water-soaked drywall from fire suppression, charred debris scattered through living spaces, or ash that keeps appearing on surfaces days after the fire means cleanup has not been done to restoration standard.
What it costs in Ontario
Fire damage cleanup as a standalone service in Ontario typically falls between $1,800 and $9,500 depending on debris volume and whether structural materials require removal.
How we do it
We remove demolition debris, clean salvageable surfaces with dry-chem soot sponges and HEPA vacuums, and dry the remaining structure with low-grain refrigerant dehumidifiers.
What Fire Damage Restoration Costs in Ontario
| Item | Typical range in Ontario |
|---|---|
| Fire damage cleanup | $1,800 – $9,500 |
| Smoke odor removal | $1,500 – $8,200 |
| Full fire damage restoration | $2,500 – $45,000 |
Prices in Ontario push higher when a Santa Ana event has forced smoke into wall cavities and attic insulation, because sealing and media blasting are the only effective options. Every job receives a written scope with photo documentation before work begins, so there is no surprise upcharge after demolition reveals the truth.
How quickly can you get to an Ontario fire job?
We dispatch to Ontario the same day you call, and we can tarp and board up within hours. Full restoration starts as soon as the structure is safe and the scope is written.
Will smoke odor come back if we do not replace drywall?
It can in Ontario’s Santa Ana season, because pressure changes draw trapped smoke particles through any unsealed gap. We seal or remove porous surfaces that hold odor, so the smell cannot bleed back.

What pushes pricing up in Ontario is the age of the roofing and stucco: hidden damage behind 1960s construction is almost always worse than the visible damage suggests, and tar-and-gravel roof failures let water travel farther before it shows. We provide a written scope with a line-item price before work begins, and we do not add change orders unless you approve them first.

What Ontario Customers Say
"Supply line let go under the upstairs bathroom at two in the morning. They had a crew here inside ninety minutes, water extracted before dawn, and dehumidifiers running by breakfast. The ceiling below was saved."
— Nicole Sutton"They did good work in a bad situation. The equipment was loud and in the house for five days, which is unavoidable but worth being prepared for."
— Divya Reddy"Explained every step while we were standing in two inches of water and panicking. Calm people are worth a lot in that moment."
