Basement Flood Cleanup Markham, ON

Rouge River watershed flooding and aging lot-level drainage cause the majority of Markham basement emergencies. Unionville's heritage core along Main Street features homes dating to the 1850s with fieldstone foundations and no modern damp-proofing. Cornell and Berczy — developed between 2005-2015 — sit on compacted fill soil that directs surface water toward foundations during heavy rain. Markham Village homes from the 1970s experience weeping tile blockages as original clay pipes deteriorate. The Rouge River, which runs through eastern Markham, flooded 280 properties during the August 2018 storm. Markham's high concentration of multi-generational households means basement living suites contain $15,000-$30,000 CAD in furnishings and electronics — raising the stakes of every flood event.
