You have three quotes on your kitchen table. One is $3,200, one is $5,500, and one is $7,500. They all say “sprinkler system installation” at the top. None of them explain why the prices are so different. You have never hired an irrigation contractor before and you do not know what separates a fair quote from a cheap one that will cost you more in repairs later. We have been installing and repairing irrigation systems in Calgary for over a decade, and we have seen what happens when homeowners choose the wrong contractor. Here are 10 questions to ask every company you interview — and the answers that should make you hire them or show them the door.
Question 1 — How Long Have You Been Installing Irrigation in Calgary Specifically
Why this matters: Irrigation in Calgary is different from irrigation in Vancouver or Toronto. Our freeze-thaw cycles, clay-heavy soils, chinook winds, and short growing season create challenges that a contractor from a warmer climate has never dealt with. A company that has been installing systems here for 5-plus years has seen how Calgary winters affect poly pipe, which heads survive snow load, and how deep lines need to be buried to stay below the frost line.
What a good answer sounds like: “We have been installing systems in Calgary for X years. Here is how we handle freeze protection, soil conditions, and seasonal timing.”
Red flag: The company is new to Calgary, cannot name specific Calgary challenges, or primarily works in another city and is “expanding into this market.” You do not want to be their learning experience.
Question 2 — Are You Licensed, Insured, and WCB-Covered in Alberta
Why this matters: In Alberta, irrigation contractors need a valid business license from the municipality where they operate. They need commercial general liability insurance — typically $2 million minimum — to cover property damage if something goes wrong during installation. And if they have employees, they need WCB (Workers’ Compensation Board) coverage. If a worker gets injured on your property and the contractor does not have WCB, you could be liable.
What a good answer sounds like: “Yes. Here is our City of Calgary business license number. We carry $2 million in liability insurance — we can provide a certificate with your name on it. Our WCB account is current and in good standing.” A reputable contractor will provide documentation without hesitation.
Red flag: The contractor hesitates, says “I’ll send that later” and never does, or tells you insurance and WCB are “not required for this type of work.” They are required. Learn more about our credentials and what to look for.
Question 3 — What Certifications Do You or Your Technicians Hold
Why this matters: The irrigation industry has recognized certifications that demonstrate technical knowledge. The Irrigation Association offers Certified Irrigation Contractor (CIC), Certified Irrigation Technician (CIT), and Certified Landscape Irrigation Auditor (CLIA) designations. For lighting, a Master Low Voltage Lighting Installer credential matters. These are not legal requirements — they are evidence that the contractor invested in professional education.
What a good answer sounds like: “Our owner/lead technician holds X certification from the Irrigation Association. We also hold X lighting certification.”
Red flag: The contractor has no industry certifications and dismisses them as “just a piece of paper.” They are not — they require coursework, testing, and continuing education.
Question 4 — Will You Do a Site Visit Before Quoting, or Are You Quoting from Google Maps
Why this matters: A quote prepared without a site visit is a guess. Water pressure varies from property to property. Soil conditions vary from neighborhood to neighborhood. A slope that is invisible from satellite imagery can require an additional zone. A contractor who quotes without visiting the property is either padding the price to cover unknowns or will hit you with change orders when those unknowns become real.
What a good answer sounds like: “We do a free on-site consultation. We measure the property, test water pressure and flow rate, check soil conditions, and design the system based on what we find. The quote is firm — not an estimate.”
Red flag: The contractor quotes a price over the phone without visiting, or says “we can finalize the details after you sign.” Sign nothing before a site visit.
Question 5 — Can You Give Me a Line-Item Quote, Not Just a Total Price
Why this matters: A quote that says “Sprinkler System — $4,800” tells you nothing. How many zones? What brand of controller? What type of heads? Are swing joints included? Is the backflow preventer included? A line-item quote shows you exactly what you are paying for and lets you compare quotes fairly. If one contractor’s price is lower, the line items will tell you what they cut to get there.
What a good answer sounds like: “Yes. Our quote breaks down zone count, controller model, head brand and quantity, backflow type, linear feet of pipe, and labor. You see everything.”
Red flag: The contractor refuses to provide a detailed breakdown, says “it’s proprietary,” or gives you a quote on a business card. You cannot compare what you cannot see. For context on what a fair system costs, read what a sprinkler system costs in Calgary.
Question 6 — What Brand of Heads and Controller Do You Use, and Why
Why this matters: Professional-grade components — Hunter, Rain Bird, Toro professional lines — last 10 to 15 years and are repairable. Hardware store brands — Orbit, generic store labels — last 3 to 5 years and are disposable. The controller brand matters too: a Hunter Hydrawise or Rain Bird smart controller is a current product with app support and weather integration. A no-name timer is obsolete technology.
What a good answer sounds like: “We use Hunter or Rain Bird professional heads and rotors because they last longer, distribute water more evenly, and parts are available everywhere in Calgary. We install Hunter Hydrawise or Rain Bird smart controllers as standard.”
Red flag: The contractor cannot name the brand they use, says “we use whatever’s on sale,” or primarily installs hardware store brands.
Question 7 — Does Your Installation Include Swing Joints on Every Head
Why this matters: A swing joint is a flexible elbow that connects the sprinkler head to the supply pipe. If a head gets run over by a mower, driven on by a vehicle, or heaved by frost, the swing joint flexes instead of snapping the pipe. Heads installed without swing joints — threaded directly into the pipe — break at the pipe connection when they get hit. The repair requires digging up the line, not just replacing the head.
What a good answer sounds like: “Yes. Every head is on a swing joint. We do not thread heads directly into pipe.”
Red flag: The contractor does not know what a swing joint is, says they are unnecessary, or quotes a lower price because they skipped them. This is a single-question elimination test. If they do not use swing joints, do not hire them.
Question 8 — How Deep Do You Bury the Pipe, and How Do You Protect It from Freezing
Why this matters: Calgary’s frost line reaches 4 to 6 feet, but irrigation pipes are typically buried 6 to 8 inches deep — shallow enough to be serviceable, deep enough to avoid surface damage. Proper burial depth combined with a thorough fall winterization blowout protects the system from freeze damage. A contractor who buries pipe 3 to 4 inches deep is cutting a corner that will cause problems.
What a good answer sounds like: “We bury poly pipe 6 to 8 inches deep. The system is protected from freeze damage by proper winterization — a compressed air blowout that clears every zone twice. We do not rely on burial depth alone for freeze protection.”
Red flag: The contractor says they bury pipe “a few inches deep” or cannot explain how freeze protection works in Calgary.
Question 9 — Can You Provide References from Calgary Customers with Similar Properties
Why this matters: Online reviews are helpful, but they are filtered. A reference you can call — or a property you can drive past — tells you more. Ask for references from customers with similar yard sizes and system types. If you have a large sloped property, ask for a reference from another sloped property. A flat, small-yard reference does not tell you the contractor can handle your site.
What a good answer sounds like: “Yes. Here are three customers who agreed to be references. One has a property similar to yours. You can call them or drive by to see the system.”
Red flag: The contractor cannot provide references, says “all our reviews are online,” or only provides references from years ago. Current references from this season or last season are what you want.
Question 10 — What Is Your Warranty, and What Does It Actually Cover
Why this matters: Warranties vary widely. Some cover parts only — you pay labor. Some cover heads but not valves or controllers. Some are 1 year, some are 3, some are prorated. And some contractors disappear the moment the warranty period ends. You want to know exactly what is covered, for how long, and how the contractor handles warranty claims.
What a good answer sounds like: “Our installation workmanship is warrantied for X years. Heads and components carry the manufacturer’s warranty — typically 2 to 5 years. If something fails under warranty, we replace it — parts and labor. You do not pay for a warranty call.”
Red flag: The warranty is vague — “we stand behind our work” with no specifics. The warranty covers parts but not labor. The warranty period is unusually short — 90 days or 1 year — suggesting the contractor does not expect the system to last.

Expert Take — The One Thing Most Homeowners Overlook When Hiring
With over a decade of experience in Calgary irrigation and landscaping, here is what we see most often: homeowners choose the middle quote without asking why the quotes are different. Price alone does not tell you anything. A $3,200 system that skips swing joints, uses hardware store heads, and buries pipe at 3 inches is not a bargain — it is a future repair bill. A $7,500 system that overspecifies commercial components you do not need is not better — it is oversold. The fair quote is the one that includes the right components for your property, explained line by line, by a contractor who answers all 10 questions without hesitation. Price is the last thing you look at, not the first. — Jaydon Grover, Owner, J.G. Irrigation Ltd.
Questions Calgary Homeowners Ask About Hiring an Irrigation Contractor
“Should I get three quotes — and what if one is significantly cheaper than the others?”
Get three quotes from contractors with similar credentials. If one quote is 30 to 40 percent lower than the other two, something is missing. Ask the low-price contractor to provide a line-item breakdown and compare it against the other quotes. The missing items are usually: swing joints, a smart controller, proper backflow prevention, or professional-grade heads. The low price is not a deal — it is a scope gap.
“Is it okay to hire a landscaper who says they ‘also do irrigation’?”
Some landscaping companies have dedicated irrigation divisions with certified technicians — that is fine. Most do not. A landscaper who installs irrigation as a side service is not an irrigation specialist. They may not understand hydraulic calculations, backflow code requirements, or proper winterization. Ask the same 10 questions. If they cannot answer Question 7 about swing joints, they are a landscaper, not an irrigation contractor.
“How soon should I book — can I wait until spring to start looking?”
The best irrigation contractors in Calgary are booked weeks in advance for spring installation. If you wait until April or May to start getting quotes, you will be scheduling installation for July or August — missing most of the growing season. Start getting quotes in February or March. Book the contractor in March for an April or May installation. The early bird gets the green lawn.
