Water damage restoration serving Markham

Markham is one of the fastest-growing cities in Canada, and its housing stock reflects that — large planned subdivisions in Cornell, Cathedraltown, and Wismer alongside the historic Unionville village core. The newer areas feature attached townhouses and detached homes built with weeping tile drainage and sump systems, while the older Unionville area has homes dating back over a century with very different drainage realities.

The Rouge River and its tributaries cross through Markham, and during major storm events the watercourses can elevate local groundwater levels significantly. Properties in lower-lying areas near Rouge Park and the creek systems can see water pushing through foundation joints even when the municipal sewer is performing normally.

Markham also has a very high density of attached townhouse and semi-detached construction. When water damage occurs in one unit, the moisture migrates. We map everything — including what has spread to adjacent spaces — so that every affected party has accurate documentation for their insurer.

Common causes we handle in Markham

  • Sewer and drain backup during heavy storms
  • Sump pump failure
  • Groundwater intrusion near Rouge River and creek corridors
  • Burst pipes in finished walls
  • Water migration between attached townhouse units
  • Appliance leaks — dishwasher, washing machine, hot water tank
  • Roof and eavestrough failures in older Unionville properties

Questions from Markham homeowners

How quickly can you respond to flooding in Markham?
We are available 24/7 and aim to have a crew on site within 1 to 2 hours of your call anywhere in Markham — Unionville, Cornell, Milliken, Cathedraltown, Thornhill, and beyond. We pick up every call personally.
Our newer Markham home flooded through the basement floor drain. How does this happen in a new build?
Newer homes in Markham still connect to municipal sewer infrastructure that can surcharge during major storms. The drain backing up is a sign that the city's sewer system is overwhelmed, not necessarily a problem with your home's plumbing. We clean up the backup, dry the area, and document everything for your insurance company.
We have a freehold townhouse in Markham and water is coming in through a shared wall. Who is responsible?
It depends on where the source is. If the pipe is in the shared wall, ownership of that pipe and the resulting damage can be complex. We document exactly where the water is coming from, which is what both your insurer and your neighbour's insurer will need to sort out the claim.
The Rouge River is nearby. Does that affect flood risk for our property?
Properties close to the Rouge and its tributaries can face elevated groundwater pressure after sustained heavy rainfall. This is separate from the municipal sewer system — it is water pushing up through the soil against foundation walls and floor joints. We assess both possibilities when we inspect.
How long does it take to dry a finished Markham basement?
Clean water jobs on a standard finished basement take 3 to 5 days of industrial drying. We monitor moisture readings every day and only remove equipment when the structure is confirmed dry throughout — not just on the surface.
