From a slow leak behind the drywall to a full basement flood, Markham property owners call Aqua Guard Water Damage because we show up with the right gear the first time — no guesswork, no upsells at the door.

Our Markham technicians hold IICRC water restoration certifications and carry that training into every job, from a Category 1 clean-water leak to a Category 3 sewage backup. We're not a call center routing you to a random subcontractor; we're the crew that shows up.
Every technician on our Markham 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.

A stain that keeps reappearing after you paint over it is a signal, not a coincidence — the moisture source behind the wall hasn't been addressed and needs a moisture meter reading, not a fresh coat of paint. Repainting without finding the source just hides the problem for a few more weeks.
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.
Carpet that stays damp or squishy days after you last noticed water is holding moisture against the subfloor, which is exactly the condition that lets mold take hold underneath.
A running-water sound when every fixture in the house is off is a strong sign of a hidden leak feeding your rising bill.
Bubbling near a window or exterior wall frequently points to a flashing or seal failure letting water into the wall cavity a little at a time.
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.
Our Ceiling Water Damage Repair process covers every stage of a water loss, from the first extraction pass to the final coat of paint, so you're never left coordinating separate contractors mid-project.
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.
We handle everything from replacing water-damaged drywall and insulation to refinishing floors, so the property is restored to pre-loss condition under one contract instead of three.
We inventory and pack out contents that need to leave the affected area during drying, then coordinate their return once the space is verified dry and repairs are complete.



You call +1-844-578-1604 and speak with a live dispatcher, not a voicemail system — we ask a few quick questions about the source and severity so the crew arrives prepared.
Technicians arrive with moisture meters and thermal cameras to map exactly how far the water has traveled, including inside walls and under flooring where you can't see it.
We set drying equipment based on the specific moisture readings taken during assessment, not a generic placement pattern.
Final verification is where a lot of shortcuts get taken industry-wide — we treat it as mandatory, not optional.
Insurance and licensing aren't just paperwork here — they're what let us stand behind the work if something doesn't go as planned.
A crew close by isn't a marketing line — it's the difference between drying equipment running in an hour versus waiting half a day.
You get a written estimate before work begins, not a surprise invoice after the drying equipment is already running.
We stand behind every job with a documented re-inspection before we consider the work complete.
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.
Call +1-844-578-1604Whether your address falls in 60428 or one of the neighboring zip codes we cover, the same crew and the same response standard applies.
We track call volume by zip code across Markham to keep crew staffing matched to where emergencies actually happen most often.

"I called in a panic at 11pm and someone actually picked up. The tech here in Markham had air movers set up before midnight and explained exactly what they were doing and why."
James R., Markham"What impressed me most was the daily moisture log — I could actually see the numbers improving instead of just being told to trust the process."
Denise M., Markham"They didn't cut corners on the contaminated water cleanup even though it would have been faster to skip the sanitization step — that mattered to me given we have young kids in the house."
Marcus T., Markham"Fast response, clear pricing, and they coordinated directly with my insurance adjuster which saved me a huge headache during a stressful week."
Priya S., Markham"Drying logs were shared with us daily so we always knew exactly where the job stood, not just a vague 'it's drying' update."
Carlos V., Markham"They minimized business disruption by sectioning off the wet area instead of shutting down the whole space during drying."
Angela F., Markham"A cracked supply line under the kitchen sink went unnoticed for days and by the time we called, the subfloor was saturated. The crew pulled the damaged material and had drying equipment running within the hour."
Tyrone B., Markham"They explained the sump discharge issue causing our crawl space flooding in plain terms and fixed it as part of the same visit instead of scheduling a separate appointment."
