Markham Context

Sewer service for Markham's established and growing communities.

Markham's older established neighbourhoods — Unionville, Thornhill, Milliken Mills, and Buttonville — were developed primarily in the 1980s with clay sewer laterals that are now entering a stage where root intrusion and pipe deterioration become common concerns. The Unionville heritage area in particular features mature tree canopy along historic streets; the roots of large oaks and maples seek moisture inside clay pipe joints, eventually causing slow drainage and recurring backups that require professional rooter service or pipe repair to resolve permanently.

Clay pipe sewer laterals in Markham's older areas are vulnerable to two related failure modes: root intrusion through joint gaps, and pipe cracking or joint offset from ground movement. Markham's clay soil in some areas undergoes seasonal expansion and contraction that can shift pipe sections out of alignment over decades of service. A sewer camera inspection documents exactly what is happening inside the pipe — whether a simple rooter service will restore flow or whether a structural repair is required — allowing us to recommend the right scope of work without over-stating or under-stating the issue.

Newer Markham subdivisions — Cornell, Box Grove, Wismer, Cathedral, and the rapidly developing areas along the 407 corridor — are equipped with PVC sewer laterals that are far less susceptible to root intrusion and cracking. However, properties in these areas approaching 15 to 20 years of age may have joint offset from settlement, or in rare cases root entry from aggressive tree root systems planted close to the sewer line. A proactive camera inspection in these areas provides peace of mind and catches any developing issues early.

Markham has a growing commercial base along Woodbine Avenue, the Steeles and Warden corridor, and the Markham Gateway business parks. Commercial sewer maintenance in these areas follows different patterns than residential — grease accumulation in food service properties, higher flow volumes in office and industrial buildings, and the operational cost implications of an unplanned sewer backup during business hours. Mechora provides commercial sewer inspection and maintenance for Markham properties in addition to residential service.
