Aqua Guard Water Damage built its Ontario operation around one standard: arrive fast, document everything with moisture readings and thermal imaging, and communicate the drying plan in plain language before we touch a single wall.
Every technician on our Ontario roster is background-checked, licensed, and insured, and every truck is stocked with commercial-grade air movers, low-grain-refrigerant dehumidifiers, and antimicrobial treatment for contaminated water intrusion.
Beyond the technical certifications, our crews are trained to communicate clearly under pressure, because a homeowner dealing with a flooded home deserves plain answers, not jargon.

Yellow-brown rings on your ceiling or walls almost always mean water has been sitting behind the surface longer than you think, and the drywall paper backing is likely already feeding mold growth. Waiting to see if the stain spreads only gives moisture more time to travel further into the structure.
If opening windows and running a fan doesn't clear the smell within a day, the moisture source is still active and needs professional extraction, not just ventilation. A smell that returns after cleaning is a strong sign the moisture is still present.
Tile that suddenly sounds hollow when you tap it often means the mortar bed underneath has been sitting in moisture long enough to lose adhesion. That hollow sound rarely resolves on its own.
A running-water sound when every fixture in the house is off is a strong sign of a hidden leak feeding your rising bill.
Wallpaper that lifts at the seams after being fine for years is often a sign that humidity or a slow leak has changed the moisture level inside that wall.
Any visible mold, even a small patch in a corner or along a baseboard, means conditions behind that surface have supported growth for a while and the moisture source needs to be found, not just the mold wiped away.
We treat Ceiling Water Damage Repair as one continuous job rather than a series of handoffs — the crew that extracts the water is accountable for the drying results, and the drying results determine what reconstruction is actually needed.
We prioritize extraction speed above everything else in the first hour, because every additional hour standing water sits raises the odds of secondary damage to subfloors and framing.
Equipment placement isn't guesswork; it's calculated from psychrometric readings taken at the start of the job and adjusted daily as conditions change.
Our sewage cleanup protocol follows IICRC S500 contamination standards, isolating the affected area, removing unsalvageable materials, and disinfecting every surface that had contact with blackwater.
If mold has already taken hold, our containment and remediation process isolates the affected zone with negative air pressure before any demolition begins, keeping spores from spreading to unaffected rooms.
Once the structure tests dry, our reconstruction team handles drywall, insulation, flooring, and trim so you're not managing a second contractor after the restoration crew leaves.
Furniture, documents, and electronics affected by water intrusion get assessed on-site, with salvageable items cleaned and stored while unsalvageable items are documented for your claim.



A real person answers, gathers the details of your water loss, and routes the closest available crew immediately.
We document the loss with photos and moisture readings before touching anything, which also protects your insurance claim.
Standing water comes out first with truck-mount equipment, then air movers and dehumidifiers go to work based on the psychrometric numbers we recorded.
Once moisture readings confirm the structure is dry, we hand you documentation and move into any needed reconstruction.
Every technician carries IICRC certification and our crews are fully insured for your protection on every job.
Local staging means shorter drive times, which matters most in the first hour after a water loss.
We'd rather explain the cost clearly upfront than have that conversation after the job is already underway.
A guarantee only means something if it's backed by a second set of moisture readings, not just a handshake at the end of the visit.
If our moisture readings don't hit a safe drying standard on schedule, we keep equipment on site at no additional cost until they do — that's the standard we hold ourselves to.
That same standard applies whether it's a single flooded bathroom or a full commercial loss — the sign-off criteria don't change based on job size.

Coverage isn't limited to the city center — our Ontario routes extend out to the surrounding suburbs so outlying addresses aren't treated as an afterthought.

"The team here in Ontario treated our emergency like it actually mattered, not like another ticket in a queue, and the drying documentation they left us was thorough enough to hand straight to our insurer."
James R., Ontario"Our basement took on water during a storm and the crew classified it, extracted it, and had dehumidifiers running the same afternoon. The final invoice matched the upfront quote exactly."
Denise M., Ontario"Professional from the first phone call to the final walkthrough. They re-tested moisture levels before closing the job instead of just eyeballing it."
Marcus T., Ontario"Fast response, clear pricing, and they coordinated directly with my insurance adjuster which saved me a huge headache during a stressful week."
Priya S., Ontario"The thermal imaging inspection found damage behind a cabinet we never would have thought to check, which probably saved us from a much bigger mold problem down the road."
Carlos V., Ontario"They minimized business disruption by sectioning off the wet area instead of shutting down the whole space during drying."
Angela F., Ontario"The tech explained exactly which boards needed to come out and which ones tested dry enough to keep, so we didn't pay to replace more than necessary."
Tyrone B., Ontario"Storm runoff got into our crawl space and the smell alone told us something was wrong. The crew found the vapor barrier had failed and fixed the actual cause, not just the symptom."
