sprinkler repair Calgary — Same-Day Irrigation Service by J.G. Irrigation
J.G. Irrigation repairs sprinkler systems throughout Calgary and surrounding communities. Broken heads, failed zone valves, mainline leaks, backflow preventer damage, controller failures — our IA-certified technicians diagnose and fix any irrigation problem. Same-day and next-day service available. Written estimate provided before any work begins. Call 587-433-4795 for fast sprinkler repair in Calgary.
Same-Day Sprinkler Repair — How Our Service Works
Most Calgary sprinkler repairs are completed in a single visit. Here is how the process works from the moment you call:
- Call or text 587-433-4795. Describe what you are seeing — a zone that will not turn on, a head spraying sideways, a soggy patch in your lawn, a water-running sound with the system off. Our technician will ask two or three questions to narrow down the most likely cause before we arrive.
- Same-day or next-day scheduling. We carry spare parts for the most common Calgary repair items — Hunter and Rain Bird heads, solenoid coils, zone valves, controller fuses, nozzles. Most common repairs require no parts run before your appointment. We work seven days a week during the irrigation season (May through October).
- On-site diagnosis with written estimate before work starts. We locate the fault, tell you what is wrong, and provide a written repair estimate. You approve the work or decline — no charge for the diagnostic visit when repair is approved. If you decline the repair, the diagnostic fee is $85.
- Repair completed same visit in most cases. Common repairs — head replacement, solenoid swap, valve repair, controller fuse or board replacement — take 15 to 60 minutes. Mainline breaks requiring excavation or complex wiring faults may require a return visit if parts must be sourced, but the diagnostic is completed same-day.
Sprinkler Repair Services We Provide in Calgary
Broken or Damaged Sprinkler Heads — $45 to $95 per head
The most common Calgary sprinkler repair. Heads break from lawn mower impact, foot traffic, shallow installation depth, or freeze damage when the system was not properly blown out the previous fall. Symptoms: a single head spraying straight up uncontrollably after the zone activates, a head that will not retract after the zone shuts off, or a dry patch in a specific area where one head in the zone is not producing coverage.
Repair: Remove the damaged head, install a matching replacement head (Hunter or Rain Bird to match existing system), adjust arc and radius to restore head-to-head coverage. Most broken head replacements take 15 to 20 minutes per location. Cost: $45 to $95 per head including labour and parts.
Freeze-damaged heads: After a winter without professional blowout, Calgary systems commonly show 3 to 8 cracked heads per zone. We assess each zone during a spring startup diagnostic and replace all damaged heads in a single visit. Cost for freeze-damage repairs typically runs $250 to $650 for a full residential system.
Failed Zone Valves — $85 to $280 per valve
Zone valves control water flow to each irrigation zone. When a solenoid coil burns out, corrodes, or fills with mineral deposits from Calgary hard water, the zone will not turn on or off correctly. Calgary water hardness (typically 180 to 220 mg/L) causes solenoid and diaphragm wear faster than in softer-water cities.
Symptoms: a zone that runs continuously even when the controller is off (stuck-open valve); a zone that will not activate from the controller (burned solenoid); water seeping into a zone when the system should be completely off (worn valve diaphragm). Valve service is typically needed on Calgary systems older than 8 to 12 years.
Repair costs: Solenoid coil replacement only — $85 to $130 (quick fix, same-day parts typically in stock). Full zone valve body replacement including labour and new Hunter or Rain Bird valve — $180 to $280. Full manifold replacement (all valves in one location) — $425 to $1,100 depending on zone count.
Backflow Preventer Repair and Replacement — $145 to $650
Calgary RPZ (Reduced Pressure Zone) backflow preventers require annual testing and replacement of internal check valve seals every 7 to 12 years. The most common symptom of a failing backflow is continuous dripping from the relief valve port between irrigation cycles. This indicates the first check valve seal has failed and the relief valve is opening to prevent backflow — the system is working as designed, but the check valve needs repair or replacement.
Internal repair (seals and springs only, body intact): $145 to $285. Full RPZ assembly replacement (when body is cracked or internal repair does not restore certification pressure): 3/4 inch — $350 to $500 installed; 1 inch — $450 to $650 installed. Annual backflow certification only (existing assembly in good condition): $95 to $120.
Controller and Timer Failures — $65 to $345
Calgary irrigation controllers fail in two ways: complete failure (zone programs lost, display blank, no response) or partial failure (some zones activating incorrectly, programming instability, display fading). Complete failures in controllers older than 10 to 15 years typically mean the control board has failed — replacement of the controller is more cost-effective than board-level repair.
We install Rachio 3 smart controllers on all Calgary replacement installations ($245 to $345 installed). Rachio connects to Wi-Fi and adjusts for Calgary weather automatically, programs to the City of Calgary odd/even watering bylaw, and provides zone-by-zone runtime history. Existing basic timer replacement with a Rachio smart controller is the most common controller upgrade we perform in Calgary.
Mainline and Lateral Line Leaks — $185 to $600
Mainline and lateral line breaks in Calgary are caused by: freeze damage from incomplete winterization; physical damage during excavation, landscaping, or fence installation; and long-term soil movement cracking older PVC systems. Symptoms: a wet patch on the lawn when no zones are running (mainline under pressure constantly); a zone that pressurizes low, with one or more heads failing to pop up; or water bubbling to the surface from a lawn area.
Repair process: Locate the break using pressure testing and soil inspection, excavate to the pipe, cut and splice in a new section of poly or PVC, compact and restore the surface. Cost depends on depth and accessibility: shallow poly line repairs — $185 to $320; PVC at deeper depth or under hardscape — $350 to $600. Under a concrete driveway or patio — quoted individually (requires saw-cutting).
Sprinkler Head Adjustment and Coverage Problems — $85 service call
Head arc, radius, and direction drift over time from physical impact, soil settling, and normal wear. Symptoms: sprinklers hitting windows, fencing, or house walls; dry patches developing in one area of a zone while another area over-saturates; zones taking longer than normal to achieve adequate coverage. Head adjustments are performed during a standard service call and are included in any diagnostic or repair visit at no additional charge. A dedicated adjustment visit when no repairs are needed: $85.
Emergency Sprinkler Repair in Calgary
Certain irrigation failures require same-day attention to prevent further damage or excessive water loss:
- Mainline break with continuous flow: A cracked mainline under constant pressure can lose hundreds of gallons per hour and will run up your City of Calgary water bill rapidly. Call 587-433-4795 immediately. If we cannot reach your property same-day, we will walk you through how to shut off the irrigation supply valve to stop the flow.
- Zone stuck open with no controller access: A stuck-open zone valve will run continuously until the system is shut off at the main isolation valve. We provide phone guidance on locating and operating the isolation valve for any Calgary homeowner while scheduling a repair visit.
- Pre-freeze emergency winterization: If frost is forecast within 24 hours and your system is not yet blown out, call immediately. We prioritize emergency winterization bookings to prevent freeze damage that costs far more to repair in spring.
Sprinkler Repair vs Full System Replacement
We provide honest recommendations on repair vs replacement. Our guideline for Calgary homeowners:
- Repair: When the system is under 12 years old, uses named-brand components, and the issue is isolated to one or two components. Repair is nearly always the right choice in this scenario.
- Phased upgrade: When the system is 12 to 15 years old with multiple component failures — zone valve manifold, controller, and backflow all failing near-simultaneously. We can phase the upgrades over one or two seasons to manage cost.
- Full replacement: When the system uses unbranded, consumer-grade components that no longer have parts supply; when pipe-level damage is extensive; or when a major landscaping redesign is underway that requires new zone layout. Full replacement cost: $3,800 to $11,500+ depending on lot size.
We will give you this assessment honestly at the diagnostic visit. We do not recommend full replacement when a $200 repair solves the problem.
