How much does sprinkler winterization cost in Calgary?

When should I winterize my sprinklers in Calgary?

Calgary sprinkler systems should be winterized before the first hard freeze, typically between late September and mid-October. Booking by September is recommended as appointment slots fill up quickly. A hard freeze (below -4°C overnight) can crack irrigation pipes within hours.

What happens if you don't winterize your sprinklers in Calgary?

Skipping winterization in Calgary can result in cracked pipes, burst valves, broken backflow preventers, and damaged sprinkler heads from ice expansion. Repair costs from freeze damage typically run $300 to $1,500 or more — far exceeding the cost of a professional blowout.

Can I winterize my own sprinkler system?

DIY sprinkler blowouts require a compressor rated at 20+ CFM at 50 PSI and precise knowledge of your zone layout. Improper technique can damage head diaphragms, crack PVC fittings, or leave water in low spots that will freeze. Most Calgary homeowners find professional blowout service the safer and more reliable option.

When should I turn on my sprinklers in Calgary in spring?

The safe window to activate your Calgary sprinkler system is mid-May to early June, once overnight temperatures are consistently above 0°C and the ground has fully thawed to at least 6 inches deep. Activating too early risks pipe damage from ground frost.

What does a spring sprinkler startup include in Calgary?

A professional spring startup includes slowly opening the main water supply valve, pressurizing each zone, inspecting every sprinkler head for damage, adjusting head rotation and arc, checking the backflow preventer, testing the controller schedule, and confirming full coverage across all zones.

How do I know if my sprinkler system has a leak?

Common signs of a Calgary sprinkler leak include soggy or waterlogged patches on your lawn, a sudden spike in your water bill, uneven watering across zones, sprinkler heads that stay up after the system shuts off, unusually green stripes in the grass, and soft or sinking spots in the yard.

How fast can J.G. Irrigation fix a broken sprinkler system?

J.G. Irrigation offers same-week sprinkler repair service across Calgary. Most residential repairs — broken heads, leaking valves, stuck pop-ups — are completed in 1 to 3 hours. Call 587-433-4795 or book online for priority scheduling.

How much does sprinkler repair cost in Calgary?

Sprinkler Zone Not Turning Off in Calgary: Troubleshooting a Stuck Zone Valve

A zone that won't turn off is a water-wasting emergency. Calgary Water restriction compliance is also at risk if a zone runs continuously outside permitted hours. Here is how to diagnose and fix a stuck-open zone, from J.G. Irrigation's IA-certified repair team.

Why a Calgary Sprinkler Zone Won't Turn Off: Common Causes

Cause	Symptoms	DIY Fix?
Debris in valve diaphragm seat	Zone runs when off; stops if manual solenoid closed	Yes — disassemble valve and flush diaphragm
Torn valve diaphragm	Zone runs continuously; pressure at valve is normal	Yes — diaphragm replacement kit available at hardware stores ($8-$15)
Solenoid stuck energized	Zone runs; controller shows zone as off	Yes — manually close solenoid by turning ¼ turn clockwise
Wiring short (zone wire grounded)	Zone runs; controller may show error; closing solenoid stops it	No — call J.G. Irrigation: $90 diagnostic
Controller zone output stuck on	Zone runs; controller terminal shows voltage when zone is off	No — controller replacement or repair needed

Immediate Steps: Stop the Zone Right Now

Locate the valve box for the affected zone (usually in a green valve box in the yard — check near the perimeter of the area that is running)
Turn the solenoid clockwise ¼ turn — this manually closes the valve regardless of the electrical signal. The zone will stop immediately
If you cannot locate the valve box: Close the irrigation main shutoff (in the basement or at the meter) to stop all zones
After stopping the zone, set the controller to turn off the program for that zone until repaired

DIY Repair: Diaphragm Flush and Replacement

Turn off the irrigation main. Open the valve cap (4-6 screws). Remove the diaphragm — inspect for debris, tears, or hardening. Flush the valve body with water. If the diaphragm is torn or hardened (common in Calgary after 8-12 years), replace with a brand-matching diaphragm kit. Reassemble and test. This repair takes 20-30 minutes and costs $8-$15 in parts.

When to Call J.G. Irrigation

Call 587-433-4795 if: the solenoid manual close does not stop the zone (pressure issue upstream); the valve cannot be located; wiring is suspected; or the diaphragm replacement did not solve the problem. Our $90 flat diagnostic includes full zone valve inspection and includes the repair quote.
