A broken or clogged sprinkler head is one of the most common service calls J.G. Irrigation receives in Calgary — and one of the most price-sensitive questions homeowners ask before calling: how much does it cost to replace a sprinkler head in Calgary? This guide breaks down the real cost by head type, labour, and scenario so you know exactly what to expect before you book.
Calgary Sprinkler Head Replacement Cost: Quick Reference
| Scenario | Typical Cost Range |
|---|---|
| Single rotor head replacement (Hunter PGP or equivalent) | $85–$130 installed |
| Single spray head replacement (Hunter Pro-Spray or equivalent) | $65–$110 installed |
| Nozzle-only replacement on existing spray body | $45–$70 installed |
| Multiple head replacement (3–5 heads, same visit) | $55–$95 per head installed |
| Full zone head replacement (6–10 heads) | $45–$80 per head installed |
| MP Rotator nozzle upgrade retrofit (per zone) | $150–$300 per zone |
What’s Included in a J.G. Irrigation Head Replacement
- Diagnosis: Confirm which heads are failed or misaligned, identify root cause (lawnmower strike, freeze damage, valve pressure issue)
- Excavation: Hand-dig the head location to expose the riser and fitting (no backhoe required for a single head)
- Parts: Professional-grade replacement head (Hunter, Rain Bird, or equivalent) and any fittings or flex riser required
- Installation: Seat and secure the new head at the correct height and arc for the zone
- Arc/radius adjustment: Set the new head’s arc and radius to match the coverage pattern required for the zone
- Run and verify: Run the zone to confirm coverage and check for leaks at the new connection
What Drives the Cost Up or Down
Number of Heads Replaced
The biggest cost driver is the service call minimum. Most Calgary irrigation companies charge a service call minimum of $90–$150 that covers the first 30–45 minutes of labour on site. If you’re replacing a single head, that call minimum represents most of the visit cost. Replacing 3 heads during the same visit spreads the call minimum across all three and reduces the per-head cost significantly.
J.G. Irrigation tip: Walk your system before calling. Mark every head that’s broken, tilted, clogged, or spraying the wrong direction. Replacing all of them in one visit is significantly more economical than booking multiple single-head visits.
Head Type
Rotor heads (Hunter PGP, Rain Bird 5000) are more complex than spray heads and carry a slightly higher part cost. However, rotors are far more durable — replacing a zone of spray heads with rotors adds cost upfront but eliminates the head-by-head replacement cycle over the next 5–10 years.
Access and Depth
Most Calgary residential irrigation heads are installed at 3–4 inch depth and accessible with a small hand spade in under 5 minutes. Deeper installations (rare; typically 5–7 inches where a head was buried by lawn topdressing over the years) take longer to access and may increase labour cost slightly.
Head Grade: Consumer vs. Professional
Consumer-grade heads (Orbit, Gilmour, and similar from hardware stores) cost $8–15 each but fail in 3–5 years under Calgary seasonal conditions. Professional-grade heads (Hunter, Rain Bird, Weathermatic) cost $18–35 each but carry 5–10 year lifespans under the same conditions. J.G. Irrigation installs professional-grade heads exclusively — the per-head part cost is higher, but the 5–10 year lifespan eliminates repeat replacement calls.
Common Causes of Sprinkler Head Failure in Calgary
Lawnmower Strike
The most common cause of single-head failure in Calgary. A rotary mower blade striking a head that hasn’t fully retracted (or that’s been installed slightly proud of grade) breaks the body or cap at the point of impact. The fix: new head at the same location, reinstalled at correct grade (flush with lawn surface when retracted, 1–2 mm below grade to provide mower clearance).
Freeze Damage
Heads that were not properly blown out before freeze-up crack internally when residual water expands. Calgary’s freeze–thaw cycling in October–November can crack heads even after a blowout if the blowout was incomplete. Freeze-damaged heads typically fail in the pattern of cracking at the riser weld, causing water to spray at ground level from the body rather than from the nozzle.
See our winterization guide for how to prevent freeze damage.
Nozzle Clogging
The mesh filter inside spray nozzles catches debris from the water line. In Calgary properties with older water mains or organic debris in the line, nozzle clogging progressively reduces flow and spray distance over the season. Symptom: spray zone that covered well at spring startup but shows dry patches by July–August. Fix: nozzle removal, cleaning or replacement.
Wear and End-of-Life
Spray heads have an average lifespan of 8–12 years in Calgary conditions. Rotors last 12–18 years. A system installed in the 2000s–2010s is at or approaching end-of-life for its spray heads — a whole-zone replacement is more economical than individual head replacement at this point.
When to Replace vs. Repair a Sprinkler Head
| Situation | Recommendation |
|---|---|
| Single head broken by mower (system otherwise new) | Replace the single head — full-zone replacement not warranted |
| Multiple heads failing on a 10+ year old zone | Replace the full zone — remaining heads are also near end-of-life |
| Nozzle clogged, body intact | Replace nozzle only — body replacement not needed |
| Freeze-cracked body | Replace full head — body cannot be repaired |
| Head tilted, not broken (sinking over time) | Reset only — no replacement required |
MP Rotator Nozzle Upgrade: Worth the Extra Cost?
If your spray zone heads are in good condition (bodies intact, risers secure) but you’re dealing with runoff issues from Calgary’s clay soil, a nozzle-only upgrade to MP Rotators is the highest-ROI repair available: $8–12 per nozzle (versus $18–35 for a full head replacement) drops the precipitation rate from 1.5–2.0 in/hr to 0.4–0.6 in/hr, matching the clay soil infiltration rate and eliminating runoff.

Frequently Asked Questions
Does J.G. Irrigation charge for the service call separately from the head replacement?
Our pricing is all-inclusive: the quote we provide before the visit covers parts, labour, and the service call. No surprise call minimum added at the end. Call 587-433-4795 for a phone estimate before booking.
Can I buy my own sprinkler head at Home Depot and have J.G. Irrigation install it?
J.G. Irrigation installs only professional-grade heads we supply — we don’t install consumer-grade heads from hardware stores. The reason: consumer-grade heads typically fail in 3–5 years in Calgary conditions, creating repeat service calls that cost more in the long run than a professional-grade head installed correctly the first time.
