How much does sprinkler winterization cost in Calgary?

Professional sprinkler winterization in Calgary costs $80 to $150 for most residential systems depending on the number of zones. J.G. Irrigation offers flat-rate pricing with no surprise fees. Call 587-433-4795 for an exact quote.

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?

Backflow Test Near Me in Calgary: City-Certified Annual Testing

The City of Calgary requires annual backflow preventer testing for every irrigation system connected to the municipal water supply, performed by a certified cross-connection control tester and submitted to the City within 30 days of the test date. If you are searching for backflow test near me in Calgary, J&G Irrigation is a City of Calgary certified cross-connection control testing company serving all Calgary communities, Airdrie (Rocky View County), Cochrane, Chestermere, and Okotoks (Foothills County).

Why Annual Backflow Testing Is Mandatory in Calgary

The backflow preventer on an irrigation system protects the City of Calgary water supply and the household water supply from potential contamination by irrigation water, which may contain fertilizer, pesticides, soil bacteria, and other contaminants from the irrigation zone. A backflow preventer that fails without detection creates a cross-connection risk. Annual testing by a certified tester verifies the device is functioning correctly and the check valves are sealing at the required differential pressure.

What the Certified Calgary Backflow Test Includes

Pressure differential test of all check valves in the backflow preventer device
Verification of relief valve function (for reduced pressure zone assemblies)
Test result documentation on the City of Calgary approved test report form
Electronic submission of test results to City of Calgary Utilities on your behalf
Written test completion certificate provided to the property owner
If the device fails: written documentation of the failure mode and required repair action
