The most important questions to ask before hiring a plumber come down to five things: confirm that they are licensed and insured, ask whether they provide upfront written pricing, check whether they offer a warranty on their work, ask about their experience with your specific issue, and confirm their availability for emergencies. These five questions separate a reliable professional plumber from a costly mistake.
Hiring the wrong plumber can mean surprise charges, unlicensed work that fails inspection, or repairs that do not last. The questions below help you choose with confidence.
The 5 Questions That Matter Most
These are the non-negotiable questions. Ask all five before any work begins, and pay attention to how the plumber answers as much as what they say. A confident, straightforward response is a good sign. Vague answers, deflection, or pushback on any of these is not.
1. Are You Licensed and Insured?
This is the most important question. In Alberta, plumbing and gas fitting work must be performed by licensed professionals. A licensed plumber has the training and certification to do the work safely and to code. Insurance protects you if something goes wrong or if a worker is injured on your property. Always confirm both before any work begins, and do not hesitate to ask for proof.
A good answer sounds like: “Yes, all our plumbers are journeyman-certified and we carry full liability insurance and WCB coverage. Happy to show you proof.” A bad answer sounds like hesitation, “we’re working on it,” or changing the subject. If they cannot produce proof of both on the spot, keep calling.
2. Do You Provide Upfront, Written Pricing?
A trustworthy plumber gives you a clear written estimate before starting work, not a vague figure over the phone followed by a much larger bill. Ask whether the quote includes all parts, labour, and any potential additional charges. Upfront pricing with no hidden fees means the price you are quoted is the price you pay.
Watch for the phrase “we charge by the hour.” Hourly billing without a cap means the final cost is unpredictable, and you have no way to budget. A flat-rate written quote, or at minimum a “not to exceed” cap, protects you from a job that takes longer than expected and a bill that reflects it.
3. Do You Offer a Warranty on Your Work?
A warranty signals that the plumber stands behind their work. Ask what is covered and for how long. A company offering a warranty on both parts and labour is confident in the quality of its repairs. If something is not right after the service, a warranty means they return and fix it at no additional cost.
Get the warranty terms in writing, not just a verbal promise. Ask specifically whether the warranty covers both the part that was replaced and the labour to install it. Some companies warranty parts only, which means you pay again for the technician’s time if that same part fails. A 1-year warranty on parts and labour is a strong baseline.
4. What Experience Do You Have With This Type of Job?
Plumbing covers a wide range of work, from a simple faucet repair to a full drain cleaning or a sewer line replacement. Ask whether the plumber has specific experience with your type of issue. An established local company that has handled your problem many times will diagnose it faster and more accurately than someone encountering it for the first time.
This matters more for complex jobs. A leaky faucet is straightforward. A slab leak, a Poly B repipe, or a main sewer line repair is not. For bigger jobs, ask how many times they have done this specific type of work and whether they can describe the process. A plumber who can walk you through what to expect without hesitation has done it before.
5. Are You Available for Emergencies?
Plumbing emergencies do not wait for business hours. Even if your current job is not urgent, it is worth knowing whether the company offers 24/7 emergency service for the future. A company that answers the phone around the clock is one you can rely on when a real emergency strikes.
Ask specifically whether they dispatch their own technicians or forward to an answering service after hours. Some companies advertise 24/7 service but route after-hours calls to a generic call centre that takes a message. You want a company that actually dispatches a plumber at 2 AM, not one that calls you back at 9 AM.
A Few More Worth Asking
Beyond the core five, these questions help round out your decision and can reveal a lot about how the company actually operates.
Are You a Local Company?
A local company knows the area, the building stock, and the relevant codes. In Calgary specifically, that means familiarity with Poly B piping in 80s and 90s builds, galvanized lines in older homes, hard water effects on fixtures, and freeze-thaw pipe risks that plumbers from milder climates may not be experienced with.
Do You Have Reviews or References?
Established companies have a track record you can check. Look for Google reviews, HomeStars ratings, or BBB accreditation. Pay attention to how they respond to negative reviews, not just the positive ones. A company that addresses complaints professionally is one that takes accountability seriously.
Will You Clean Up After the Work?
A professional leaves your home as they found it. This sounds small, but it separates companies that respect your property from ones that do not. Ask before work begins, not after you find pipe shavings in your carpet.
Who Will Actually Do the Work?
Confirm the work is done by the company’s own qualified technicians, not subcontracted out. Subcontracting is not always a problem, but when it happens without your knowledge, you lose visibility into who is in your home and whether they meet the standards you were promised.
Red Flags to Watch For
Be cautious of a plumber who:
- Cannot or will not provide proof of licensing and insurance
- Refuses to give a written estimate
- Asks for full payment upfront before any work is done
- Pressures you into a major repair or replacement without a clear explanation
- Has no verifiable local presence or reviews
One more worth adding: be wary of a quote that is dramatically lower than everyone else’s. In Calgary’s plumbing market, pricing is competitive but not wildly variable for the same scope of work. A quote that undercuts three other bids by 40% usually means corners are being cut somewhere, whether that is in parts quality, labour qualifications, or warranty coverage. The cheapest quote is rarely the cheapest outcome.
What Licensing Actually Means in Alberta
Alberta requires plumbers to hold a valid journeyman certificate issued through the Alberta Apprenticeship and Industry Training (AIT) program. This means they have completed a four-year apprenticeship under a certified journeyman and passed a provincial exam. Gas fitting work (water heaters, furnaces, gas lines) requires a separate gas fitter certification.
Beyond the individual plumber’s ticket, the company itself should be registered and carry both general liability insurance and Workers’ Compensation Board (WCB) coverage. WCB matters because without it, if a worker is injured on your property, you could be held liable. Ask for the company’s WCB clearance letter if you want to be thorough.
