Restoration Services in Ontario

When a pipe bursts, a fire tears through a kitchen, or mold surfaces behind drywall, Ontario property owners need a restoration crew that knows the Inland Empire, not one learning the area on your dime. Dry County Restoration operates out of Corona, runs 24/7, and handles water damage, fire and smoke damage, mold remediation, and biohazard cleanup across Ontario and the surrounding San Bernardino County communities. Call (951) 667-9910 any time.

Restoration emergencies common in Ontario

Ontario sits in a basin where the Santa Ana winds accelerate out of the passes to the east and north, driving wildfire smoke and embers into neighborhoods with little warning. That same geography funnels winter storms off the mountains, and when those storms hit impervious surfaces, the concrete, asphalt, and compacted soil that cover much of the city, water moves fast and pools against foundations. Ontario’s older residential blocks were built during Southern California’s postwar and 1960s–70s construction booms, and the plumbing in those homes has had decades to corrode, crack, or fail at joints. Meanwhile, the city’s continued industrial and warehouse development along the I-10 and SR-60 corridors means commercial property managers deal with their own set of risks: roof drainage failures, sprinkler activations, and the particular challenge of large open floor plans that can hold thousands of gallons before anyone notices.

Summer humidity spikes, brief but real in the Inland Empire, create conditions where a slow leak behind a wall can seed mold colonies within days. Ontario’s dry-season baseline makes that window feel deceptive: surfaces look fine long after moisture has migrated into framing and insulation.

Services we provide in Ontario

Water damage restoration

Water damage in Ontario frequently starts at the supply lines and drain connections that were original to homes built in the 1960s and 1970s, galvanized steel that has slowly narrowed with mineral buildup, or older copper fittings that have worked loose over decades of thermal cycling. When water gets under slab-on-grade construction, which dominates Ontario’s residential stock, it has nowhere obvious to go. Moisture meters and thermal imaging locate saturation that looks dry at the surface, and industrial drying equipment, air movers, desiccant or refrigerant dehumidifiers, runs until readings confirm the structure is genuinely dry, not just surface-dry.

Fire and smoke damage restoration

After a fire, the visible char is rarely the full story. Smoke residue travels through HVAC systems, settles into porous materials, and leaves an odor that resurfaces weeks later if the affected materials aren’t properly cleaned or removed. Ontario’s Santa Ana wind events can push smoke from a contained kitchen fire into every room of a house in minutes. Restoration scope here includes structural assessment, controlled demolition of unsalvageable materials, odor neutralization, and coordination with your insurance adjuster on documentation.

Mold remediation

Mold remediation in Ontario requires containing the affected area before any disturbance begins, disturbing mold without proper containment spreads spores to unaffected spaces. Work follows established industry protocols for removal, surface treatment, and post-remediation verification. Older Ontario homes with original drywall or plaster are particularly susceptible once moisture has been present for more than a day or two.

Biohazard and specialty cleanup

Biohazard cleanup, including sewage backups, which are not uncommon when Ontario’s older clay sewer laterals root-intrude or collapse, requires personal protective equipment, proper waste disposal, and thorough disinfection. This work is handled discreetly and disposed of in compliance with applicable regulations.

Coverage and how fast we can get there

Dry County Restoration’s home base in Corona puts Ontario roughly 10 to 15 miles west, depending on the part of the city. The most direct route runs west on the 91 to the 15 north, or via Ontario Avenue and surface streets for neighborhoods closer to the city’s eastern edge near Haven Avenue. The Ontario Mills area, the neighborhoods around Ontario International Airport, and the residential blocks north toward Euclid Avenue are all reachable without navigating the worst of the 10 Freeway interchange congestion if crews time the run right. Because we operate 24/7, dispatch happens around the clock, not just during business hours when traffic is heaviest.

Building stock, site conditions, and permits in Ontario

Most of Ontario’s single-family residential neighborhoods were developed between the late 1940s and the mid-1980s, with the heaviest concentration of tract homes dating to the 1960s and 1970s. These homes are overwhelmingly slab-on-grade, basements are rare in this part of San Bernardino County, with stucco exteriors over wood framing. Plumbing in that era typically means galvanized steel supply lines that have been corroding for fifty-plus years, and cast-iron or clay drain lines that are vulnerable to root intrusion. Homes built before the mid-1970s may contain asbestos in floor tile, popcorn ceilings, or duct insulation, and lead paint is a realistic possibility in pre-1978 construction, both of which affect how a restoration scope is planned and priced.

Ontario’s soils in the lower valley areas include alluvial deposits that drain reasonably well in dry conditions but can become saturated quickly during heavy rain, increasing hydrostatic pressure against slabs and stem walls. The city’s Building and Safety Division issues permits for structural repair and reconstruction work; work that involves opening walls, replacing roofing, or altering structural members will generally require a permit and inspection before close-up. Ontario falls within a seismically active zone, standard for the Inland Empire, and restoration scopes that involve structural repairs need to account for current California Building Code requirements.

If your property has been damaged and you’re not sure what the permit process looks like for your specific situation, the restoration scope documentation we provide can help you and your contractor navigate that conversation with the city.
