Where is the water coming from?
| What you see | Likely source |
|---|---|

| Water near the water heater or washer | Appliance or supply leak |
| Dripping from above | Plumbing leak on an upper floor |
Why Markham basements flood
Clay soil, high spring water tables, intense summer storms and a mix of old and new sewer systems combine here. Older neighbourhoods may have downspouts or weeping tile still tied to the sewer. Newer areas rely on sump pumps that can fail. Finished basements, now common across the city, raise the stakes.
How we help
- We find and stop the source.
- We clear any blocked drains or sewer lines.
- We repair or replace failed sump pumps.
- We look at long-term protection: a backwater valve, a backup pump, downspout changes.
From the van: Drying and restoration are separate trades. We focus on stopping the water and preventing the next flood.
Clear water and sewage are two different floods. We find out which before anyone mops.
What changes the cost
The source, how much water, the time of call, and whether protective devices are added afterward all affect the price. Some protection work may qualify for City of Markham subsidies; check the current terms.
Call before it gets worse
Moisture under flooring and behind drywall starts mould growth within a day or two. Stop the water fast, then dry it out.
