When Ontario homeowners and business operators deal with mold, they need a company that knows the area, shows up fast, and gives them a binding written price before touching anything. That's Roof Repair Smedway. Our certified crews serve Ontario and surrounding CA communities with the same standard on every job — IICRC S520 protocol, written flat-rate pricing, and a satisfaction guarantee in writing.
We don't subcontract in Ontario. We don't send uncredentialed labor. We don't begin work without a signed written estimate. These aren't competitive points — they're the operating standards that have earned us the Ontario customers who call back and refer friends.
We handle every phase of Roof Repair in Ontario in-house. No subcontracting, no referrals, same certified standard from first call to final clearance test.
Mold emergencies in Ontario don't wait for business hours. When a pipe bursts, a storm floods a crawl space, or water damage creates conditions for rapid mold growth, Roof Repair Smedway dispatches immediately. Our emergency line for Ontario is live 24/7 with real dispatchers — not voicemail, not a callback window.
HEPA air scrubbers, negative pressure containment, industrial dehumidifiers, antimicrobial supplies — Ontario emergency crews arrive with everything deployed on arrival. We stop the spread before it reaches unaffected areas.
We find every affected area in your Ontario home — including growth hidden inside walls, beneath flooring, in crawl spaces, and in attic spaces. We document everything before quoting anything.
After inspection, you receive a complete written itemized estimate for your Ontario project. The process follows IICRC S520 from containment setup through antimicrobial surface treatment and post-clearance air testing.
We've worked in Ontario area restaurants, medical facilities, retail spaces, warehouses, and multi-unit residential buildings. HVAC-distributed mold is assessed on every Ontario commercial inspection as standard.
Post-remediation verification reports are provided on every Ontario commercial project — meeting insurance carrier, OSHA, and property management requirements. Call +1-855-469-0306 for a Ontario commercial site assessment.
Not sure if your Ontario property has an actionable mold problem? Our inspection delivers documented answers — calibrated air sampling through certified labs, thermal imaging, moisture mapping, and surface swabs to build a complete picture before any remediation is recommended.
Written report delivered within 24 to 48 hours of the Ontario site visit. Call +1-855-469-0306 to schedule.
Toxigenic mold species — particularly Stachybotrys — appear in Ontario properties with histories of water damage or chronic moisture. They require full containment, PPE-equipped removal, and HEPA air scrubbing throughout the entire work period. Our Ontario black mold protocol starts with confirmed species identification through certified lab analysis — not a visual assumption.
After removal, every exposed surface in your Ontario property receives EPA-registered antimicrobial treatment specific to toxigenic species. The job closes with post-clearance air sampling and a written clearance report.
Remediation removes the active colony. Prevention keeps it from coming back — which in Ontario's humidity conditions requires addressing the moisture source directly. Every Roof Repair Smedway project in Ontario includes moisture source identification and documented prevention recommendations as standard deliverables.

Homeowners and business operators in Ontario — real testimonials from people who called Roof Repair Smedway when mold became a real problem.
Found black mold in our Ontario home after a hidden plumbing leak. Called Roof Repair Smedway at 9 PM expecting voicemail. Someone answered immediately. Crew was at our Ontario property the next morning with a written estimate before they looked at anything. Done in 48 hours, air clearance test passed, price matched exactly what they quoted. That's exactly how it should work.
I manage commercial properties in Ontario and I've dealt with enough remediation contractors to know the difference. Roof Repair Smedway knows the protocol — contained the Ontario property, kept adjacent tenants operational, complete insurance documentation at close. They're the only company I call for Ontario commercial remediation now.
Two years of musty smell in our Ontario basement we kept blaming on old construction. Finally tested it — significant mold behind the drywall. Roof Repair Smedway removed it, treated the framing, recommended dehumidification, did a 30-day follow-up test. Clean. Two years of guessing solved in one week.
Clear information before any Ontario property owner commits to anything.

Our Ontario documentation is structured to meet insurance carrier requirements, and we can communicate with your adjuster directly. We can't guarantee coverage outcomes — but we give you the strongest possible documentation to support your Ontario claim review.
Properly performed remediation eliminates the active colony. Recurrence happens when the underlying moisture condition isn't resolved — because mold spores are naturally present in every indoor environment at trace levels. Every Roof Repair Smedway project in Ontario addresses the moisture source as a required deliverable. We identify the cause, document it, and provide specific prevention recommendations for your Ontario property type. Our optional maintenance program includes 30-day and 90-day follow-up air quality checks for Ontario customers.
Beyond Ontario, we serve neighboring communities across CA with the same certified standard.
