When a pipe fails inside your Markham property, every minute it runs adds to the total damage scope. Our local team stops the loss, extracts the water, and begins drying immediately — and we handle the insurance documentation the same day.
The thing that separates a burst pipe cleanup done right from one done poorly is the ability to find and dry the water you can't see. Wall cavities, subfloor assemblies, and ceiling voids absorb water fast and dry slowly — and if any moisture is left behind, mold follows within days. Here's what makes COS Water Damage Restoration the right call in Markham.
You can't dry what you haven't found. Thermal imaging is how we find it.
Fast arrival with the right equipment is how burst pipe losses are kept manageable.
Our Markham team arrives, secures the water source (shutting the main if necessary), and directly coordinates with a licensed plumber to complete the pipe repair before cleanup begins. We've established working relationships with licensed plumbing contractors across Markham and IL — so you're not trying to find a plumber at 2am while water is still running.
Burst pipe claims in Markham require moisture mapping data, pre-drying and post-drying readings, Xactimate line-item scopes, and photo documentation. Our Markham team builds this file from the first tool we pick up — so when your adjuster requests documentation, everything they need is already prepared and formatted to their carrier's standard.
Here's the full scope of what our Markham Burst Pipe Cleanup specialists handle on every job.
The first priority when our Markham crew arrives is stopping the water source. If the affected valve or supply line is accessible, we isolate it directly. If the break is inside a wall or in an inaccessible location, we shut the main supply and work with a licensed plumber to locate and repair the rupture before cleanup begins. Stopping the source is not the cleanup company's job in a literal trade sense — but it's absolutely the first 15 minutes of our time on every Markham burst pipe call, and we coordinate it aggressively.
Complete extraction cuts drying time significantly and reduces the risk of secondary damage.
Without moisture mapping, drying programs are guesswork. With it, they're calibrated.
Wall cavity drying is where most burst pipe jobs either succeed completely or fail at the last 10%.
Burst pipe damage is typically a covered peril under standard homeowner's policies in IL, provided it was sudden and accidental — as opposed to slow leak damage, which most carriers exclude. Our Markham claim coordinators know the language and documentation requirements that lead to approved scopes and know how to document the event timeline in a way that clearly supports the sudden-loss language most policies require. We file the claim, coordinate the adjuster, and follow the settlement through to completion.
One company, documented from first arrival through final rebuilding.


Live dispatch. Immediate crew deployment. ETA confirmed during your call.
Arrival to source secured to extraction started — our Markham crew moves through these steps as a single continuous sequence, not staged phases.
After moisture mapping is complete, our Markham project manager prepares a written, Xactimate-based scope covering extraction, material removal, wall cavity drying, equipment staging, and reconstruction. You review the scope before any equipment is deployed or material is removed. If the adjuster is involved, our coordinator files the claim the same day.
Daily updates, documented readings, final walkthrough with you — every time.



"The morning we found a burst pipe in our Markham home, I was convinced we were looking at months of repair. COS Water Damage Restoration changed that. Their crew arrived fast, found water I didn't know existed using their thermal camera, and coordinated everything — plumber, insurance, reconstruction — under one project. We were back to normal faster than I thought was possible."
"What impressed me most was the moisture mapping session. Our burst pipe was in the second-floor bathroom, and COS Water Damage Restoration's tech found water in the wall cavity adjacent to the pipe, inside the ceiling of the first floor below, and along a wall run in the living room — none of which had any visible surface water. They set up drying for all of it, hit it with daily readings, and everything came back confirmed dry before reconstruction started. That level of thoroughness is exactly what you want from a company doing this type of work."
"I've dealt with two burst pipes in Markham properties over the years. The first time I called a general contractor who 'also does water damage' — they dried the surface and called it done. Mold behind the walls within six weeks. This time I called COS Water Damage Restoration specifically, and the difference was obvious from the first hour. They mapped everything with thermal imaging, set up cavity drying through wall access holes in the framing, ran the program for 9 days, and confirmed completion with documented instrument readings. No mold, no callbacks, no surprises."
