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.
Musty odors that seem to follow you from room to room often mean the HVAC system is circulating spores from a hidden wet area, which spreads the problem rather than solving it.
Hardwood that's cupping at the edges or laminate that's separating at the seams is a classic sign of moisture intrusion from below, whether that's a slab leak or groundwater seepage. The longer it sits, the harder the flooring is to salvage.
A running-water sound when every fixture in the house is off is a strong sign of a hidden leak feeding your rising bill.
Paint that bubbles or peels away from a wall, especially near baseboards, usually means moisture is pushing through from behind rather than a simple application problem.
Mold that returns after cleaning with bleach is a sign the underlying moisture source was never addressed, since surface cleaning does nothing for saturated material behind the wall.
Our Mold Remediation 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.
Because mold can establish in as little as 48 hours, our drying timeline is built around beating that window rather than treating mold prevention as an afterthought.
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.
Specialized cleaning techniques can often save upholstery, electronics, and documents that look like a total loss at first glance, which keeps out-of-pocket replacement costs down.



A real person answers, gathers the details of your water loss, and routes the closest available crew immediately.
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.
We operate under proper licensing and insurance in every market we serve, with documentation available on request.
Local staging means shorter drive times, which matters most in the first hour after a water loss.
Flat-rate pricing means the number we quote is the number you pay, regardless of how long the drying cycle takes.
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.
Our technicians don't get paid faster by closing jobs early, which keeps the incentive aligned with actually finishing the drying properly.

We track call volume by zip code across Markham to keep crew staffing matched to where emergencies actually happen most often.

"A pipe burst behind our water heater and the crew here in Markham had extraction units running within 40 minutes of my call. They walked me through the moisture readings every day until it was fully dry."
James R., Markham"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., Markham"The sewage backup in our laundry room was handled with full PPE and proper disposal of the ruined flooring. I appreciated that they explained the Category 3 contamination process before starting."
Marcus T., Markham"The reconstruction crew matched our original flooring almost perfectly after the water damage repair — you'd never know there was a leak."
Priya S., Markham"We had a slow leak we didn't notice for weeks and the crew found moisture in places we never would have checked using thermal imaging."
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"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., 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."
