What sprinkler winterization costs in the GTA
Winterization uses compressed air to clear every lateral line, valve and head before freezing weather. Water left in the system splits pipe and cracks valve bodies — repairs that cost far more than the service itself.
Typical pricing
| Item | Price | Notes |
|---|---|---|
| Standard winterization | $99 | Typical residential system |
| Larger multi-zone systems | quoted on site | More zones, longer blowout time |
| Annual maintenance membership | $179 / year | Startup and winterization together with priority scheduling |
What changes the price
- Number of zones and total pipe length
- Access to the backflow device and blowout point
- Whether the controller needs to be shut down and drained
- How late in the season you book — peak weeks fill first
Common questions
- When should winterization be done?
- Between early October and mid-November in the GTA, before the first hard frost.
- Can I blow the system out myself?
- A home compressor rarely moves enough air volume to clear the lines, and too much pressure damages heads and seals.
