How to Choose an Irrigation Company in Calgary — 8 Questions to Ask in 2026

With dozens of irrigation companies operating in Calgary, choosing the right one for installation, startup, blowout, or repair is not always obvious. Price alone is a misleading guide — a $40 blowout from an underpowered handyman can cost $1,500 in spring repairs. This guide gives you eight questions that separate professional irrigation companies from seasonal contractors.

The 8 Questions Every Calgary Homeowner Should Ask

1. Are you IA Certified?

The Irrigation Association (IA) offers certifications for irrigation technicians, contractors, and designers. A Certified Irrigation Technician (CIT) has completed structured training in hydraulics, system design, and maintenance. In Calgary’s climate, proper winterization technique is critical — and IA training covers it specifically. J.G. Irrigation is IA Certified.

2. What compressor CFM do you use for blowouts?

The correct answer is 50 CFM minimum for residential systems. A contractor who says “a large compressor” without knowing the CFM rating doesn’t understand why CFM matters. Ask specifically: “What CFM is your blowout compressor?” Any number under 25 CFM is a red flag.

3. Do you carry general liability insurance?

irrigation installation requires excavating your property. Any contractor without liability insurance leaves you personally liable for damage. Ask for the certificate — a legitimate company will provide it instantly. J.G. Irrigation carries $2M general liability.

4. How many passes do you run per zone during blowout?

The correct answer is 3–5 passes per zone. One pass is insufficient to guarantee complete clearance. Any contractor claiming “one pass is enough” does not understand the winterization process.

5. Do you leave a written service record?

Best practice is a written record left at the controller after every service visit: date, technician name, work completed, problems found, and next recommended service. Verbal-only service is not traceable if something goes wrong.

6. What brands do you install?

Hunter and Rain Bird are the industry-standard brands in Calgary — both have extensive parts availability and local supplier support. Be wary of unknown or big-box store brands that may not have local parts. J.G. Irrigation installs exclusively Hunter and Rain Bird components.

7. Can you provide references from Calgary customers?

Google reviews are the fastest check. Look for consistent mentions of: shows up on time, cleaned up after the job, explained the system, fixed issues promptly. Avoid companies with reviews mentioning “no show”, “ghosted”, or “damage not repaired.”

8. Do you have WCB coverage?

Workers’ Compensation Board (WCB) coverage protects you from liability if a worker is injured on your property. In Alberta, hiring an uninsured subcontractor without WCB coverage can expose you to injury claims. Ask for the WCB clearance letter. J.G. Irrigation carries active WCB coverage.
