Historic Unionville and older Thornhill sections carry drain infrastructure decades older than Markham's newer communities like Cornell and Cathedraltown, which means the plumbing issues we see vary block by block. Older sections see more root intrusion and clay pipe wear; newer sections see more grading and sump reliability calls.
Regardless of the neighbourhood's age, our approach stays the same: camera-verify before recommending any repair, and size waterproofing and sump systems to the property's actual conditions.
What makes Markham different
- Root intrusion and clay pipe repair for historic Unionville and Thornhill homes
- Sump pump and grading-related waterproofing for newer Cornell and Cathedraltown builds
- Backwater valve installation across all of Markham
- Same-day emergency response throughout Markham
