Standing water in your Markham property is a race you're losing every minute. Our truck-mounted water removal systems extract thousands of gallons per hour — and our Markham crew can be at your door in under 60 minutes, any hour, any day.
The right water removal team in Markham gets to you fast, removes the water completely, and transitions immediately to structural protection — not a service that extracts visible water and leaves hidden moisture to fuel mold growth.
Local crews and pre-staged equipment mean our Markham Emergency Water Removal team arrives faster than regional contractors every time. We target 60 minutes from your call to boots on the floor.
We don't turn jobs away based on contamination category. Our Markham crew handles Cat 1 through Cat 3 with the proper protocols for each.
Emergency doesn't mean blank check. Before extraction begins, our Markham team provides a written, Xactimate-based scope and cost estimate for your review and approval. The number you approve is the invoice you receive.
We document everything at the extraction phase — before conditions change and evidence is lost.
Every Emergency Water Removal scenario requires the right equipment, the right technique, and the right team. Here's what we handle in Markham.
Rapid volume removal at this stage prevents saturation from reaching framing and subfloor materials.
Fast extraction at the point of failure combined with cavity access drying limits the drywall and framing removal scope.
Basement and crawlspace flooding in Markham requires submersible and portable extraction systems capable of working in low-clearance and confined environments. Our crews carry the right equipment for each scenario — including high-capacity submersible pumps for deep standing water and portable extractors for post-pump residual water in below-grade spaces.
We never use standard extraction equipment on contaminated water events — cross-contamination risk is real, and proper equipment matters.
Our Markham crew extracts surface water and immediately transitions to moisture detection to catch sub-surface migration before drying equipment placement.
Water events in Markham commercial properties carry additional complexity: larger square footages, infrastructure like server rooms and electrical panels, business interruption risk, and tenant notification requirements. Our commercial Emergency Water Removal team in Markham deploys at scale — multiple extraction units, larger crew sizes, after-hours scheduling to minimize disruption — and maintains a dedicated project manager for commercial loss communication.


Every call connects to a real person who starts your Markham response before you hang up.
Our Markham Emergency Water Removal crew loads the extraction equipment specific to your scenario during transit so they're productive within minutes of arrival. Our target is on-site in 60 minutes or less, with your dispatcher providing real-time updates if conditions change en route.
On arrival, our crew assesses the water source, category, and extent of migration before placing any equipment. A written scope and cost estimate is prepared and reviewed with you before extraction begins — the number you approve is the invoice you receive.
Extraction continues until standing water is completely eliminated and surface moisture is at levels appropriate for structural drying handoff. Our crew immediately stages dehumidifiers and air movers to begin the drying phase — preventing the 24-48 hour mold risk window from opening.



"A pipe burst in our Markham home's basement at 11 p.m. on a Saturday. I was bracing for a long night of being on hold. COS Water Damage Restoration answered on the second ring, had a crew at my door in 52 minutes, and the standing water was completely out before 2 a.m. They stayed to set up the drying equipment and I woke up to a dehumidifier running and a dry basement floor. Absolutely excellent."
"A sump pump failure let in about 4 inches of water across our entire finished basement in Markham. I found it at 6 a.m. on a Monday. COS Water Damage Restoration was on site by 7:15, had the water out by 10, and the drying equipment running before I left for work. The moisture mapping showed water under our LVP flooring that would have become a mold problem if we hadn't caught it. Grateful for the thoroughness."
"Three different companies told me they could help with our Markham storm flooding. Only COS Water Damage Restoration showed up with a truck-mounted extraction unit instead of a few shop vacs. The difference in output was enormous — they pulled the water out in a fraction of the time I expected. Highly recommend calling them first."
