Trusted Water Damage Restoration in Markham
Pro Max Restoration provides round-the-clock water damage restoration across Markham. Whether you own a heritage home in Unionville, a newer build in Cornell or Berczy, or a family home in Markville or Greensborough, our IICRC-certified technicians reach you in about 45 minutes with truck-mounted extractors and commercial drying equipment to stop the damage before it spreads.
As one of Canada's fastest-growing municipalities, Markham blends established neighbourhoods with rapid new construction — and each brings its own water risks, from aging drain lines to builder-grade fixtures that fail early. We handle everything from clean-water leaks to Category 3 sewage backups, prevent mold, rebuild, and bill every major Canadian insurer directly so a covered loss costs you nothing out of pocket.

Common Causes of Water Damage in Markham
After 600+ GTA restoration projects, we know exactly how Markham homes are affected — and how to fix it for good.
Rouge River & German Mills Creek Flooding
Homes near the Rouge River and German Mills Creek corridors face overland and basement flood risk during intense summer storms and rapid spring melt, when these watersheds rise quickly.
Deep Finished Basements
Many Markham homes feature large, fully finished basements with hardwood, built-ins and home theatres. A sump-pump failure or burst line turns a small leak into a five-figure loss without fast extraction — exactly what our 45-minute response prevents.
New-Build & Builder-Grade Plumbing
Markham's rapid growth means many homes in Cornell, Berczy and Greensborough run economy hot-water tanks, valves and supply hoses that commonly fail at the 8–12 year mark, flooding finished basements within minutes.
Many of these emergencies start as a flooded basement or a sewer backup, and standing water quickly leads to mold. Catching it fast is what protects your Markham property — request a free quote or call us the moment you spot water.
Markham Water Damage Restoration for Rouge River Basements and New Builds
Markham stretches across the Rouge River and German Mills Creek corridors, and homes near these waterways in neighbourhoods like Milliken Mills and Markville face real risk when heavy rain pushes creek levels up faster than storm drains can handle. Markham's deep, fully finished basements amplify the stakes, since standing water can spread across hundreds of square feet of finished flooring before it is even discovered. Pro Max Restoration delivers emergency water removal across Markham in approximately 45 minutes, because a flooded basement in Markham left untouched overnight can mean the difference between a straightforward dry-out and a full flooring and drywall replacement.
Heritage Unionville homes bring a distinct challenge, with original drain tile and plumbing systems now decades old and increasingly prone to slow leaks and backups that demand careful, methodical water damage restoration in Markham rather than a quick surface fix. Just a few kilometres away, fast-growing communities like Cornell, Berczy, and Greensborough face the opposite problem, where builder-grade water heaters and supply hoses installed during construction routinely fail at the eight to twelve year mark, triggering sudden burst pipe repair calls in homes that still look brand new. Our crews carry thermal imaging cameras and moisture meters to every job so hidden water is found and addressed regardless of the home's age.
Whether the source is Rouge River overland flooding or a failed supply hose behind a new-build dishwasher, Pro Max Restoration works inside the critical 24 to 48 hour drying window to prevent mold from taking hold in Markham homes. We are IICRC S-500 and S-520 certified with 15+ years of experience and 600+ completed GTA projects, and we bill Intact, Aviva, Desjardins, TD, Wawanesa, and Co-operators directly so Markham homeowners are not left negotiating with their insurer alone. Backed by a 5.0 Google rating from 11 reviews, we handle everything from extraction through full rebuild. Call 416-988-3539 for a rapid response.
Signs You Need Water Damage Restoration in Markham
Water damage is rarely limited to what you can see. If any of these warning signs appear in your Markham property, call 416-988-3539 right away, because the first 24 to 48 hours decide whether materials can be dried and saved.
- Standing water, damp carpet or a musty smell in the basement
- Water stains, bubbling paint or sagging drywall on ceilings and walls
- Warped, cupping or lifting hardwood, laminate or vinyl flooring
- A sudden unexplained spike in your water bill
- Peeling baseboards, efflorescence or white chalky residue on foundation walls

Our IICRC-certified crews are on call 24 hours a day, 365 days a year and reach Markham in about 45 minutes with the equipment to stop the damage immediately.
Our Water Damage Restoration Process in Markham
Every Markham water damage project follows the same proven, IICRC S-500 process, from the first emergency call through to the final rebuild.
Emergency Call & 45-Minute Dispatch
Call us any hour and our emergency coordinator gathers the critical details, the water source, the affected rooms and any safety concerns, then dispatches the nearest crew to Markham. We talk you through shutting off the water and power while the team is on the road.
Inspection & Moisture Mapping
Our IICRC-certified lead technician uses FLIR thermal-imaging cameras and calibrated moisture meters to map every wet surface in your Markham property, including hidden moisture inside wall cavities and under subfloors that a visual inspection always misses.
Emergency Water Extraction
Truck-mounted and portable extractors remove standing water fast, up to 25 gallons per minute. We set containment to stop the water spreading into dry areas of the home and protect furniture, flooring and contents while extraction is underway.
Structural Drying & Dehumidification
We position commercial air movers and LGR dehumidifiers to create targeted airflow, then monitor moisture readings daily and adjust the equipment until every material reaches the IICRC S-500 dry standard. Most Markham homes dry in three to five days.
Cleaning, Sanitizing & Mold Prevention
Antimicrobial treatments stop bacteria and prevent mold taking hold in the wall cavities. HEPA air scrubbers clear airborne particles and hydroxyl generators neutralize odours at the molecular level rather than masking them with fragrance.
Full Restoration & Insurance Handoff
Our in-house construction team rebuilds everything that was removed, from drywall and paint to hardwood and cabinetry, returning your Markham property to pre-loss condition. We submit the full photo and moisture documentation and bill your insurer directly.
