Lawn sprinkler service & repair in Markham.

In Markham, the safe window for spring opening is typically the second week of April through mid-May, after the last hard frost. Opening too early risks freeze damage to backflow assemblies and exposed risers. We start booking in late March and prioritize repeat customers first — book early to lock in your preferred week.

Our service call (mobilization + on-site assessment) is $95. Repair labour is billed at $95 from there. Common parts costs: sprinkler head replacement $68, pipe break repair from $120, full 3-valve manifold rebuild starting at $135 plus valves. If our AI-Smart-Intake diagnostic tool correctly predicts the fix, you get one hour of repair labour free on the diagnosed work — our only standing discount.

Yes — during the active irrigation season (mid-April to mid-October), we hold same-day repair slots for Markham addresses booked before 11 AM, subject to availability. Most Markham calls land within 4–6 hours of dispatch.

Markham falls under York Region's Outdoor Water-Use Bylaw with stricter local variations. From June 1 to September 30, residential watering is permitted on odd or even calendar days matching your house number, in EITHER the 6 a.m. to 9 a.m. window OR the 6 p.m. to 9 p.m. window — not both. New sod and seed get a two-month grace period. Commercial properties are limited to a three-hour window between midnight and 6 a.m. We program your controller to comply during spring opening.

The Ontario frost line in York Region is approximately 1.2 metres (4 feet), but irrigation lines don't need to be buried that deep — they're drained and pressurized only during the warm months. PJL buries mainlines 8–12 inches deep and laterals 6–8 inches deep, which is standard for the GTA. Fall winterization (compressor blowout) is what protects them from freeze damage, not depth.
