How to Choose a Plumber in Calgary: 7 Questions to Ask

Short answer: Ask any Calgary plumber seven things before you book: are you a certified journeyperson, are you insured and WCB registered, who actually does the work, will I get the price in writing first, do you pull permits, do you stand behind the work, and will you tell me if I do not need it. A good plumber answers all seven plainly.

Anyone can put a wrench on a magnet sign. These questions take two minutes and separate a licensed journeyperson from someone who will leave you with a callback.

Numbered list of seven questions to ask a plumber before you book: certified journeyperson, insured and WCB registered, who does the work, price in writing first, permits, standing behind the work, and telling you if you do not need it. — The seven questions to ask any plumber before you book, from certification and insurance to permits and whether they will tell you if you do not need the work.

The seven questions

Ask	A good answer	A red flag
1. Are you a certified journeyperson plumber in Alberta? Are you a certified gasfitter?	Yes, with a name you can look up	Vague answers, or "I've been doing this for years"
2. Are you insured and WCB registered?	Yes, and they will show you	Reluctance to share proof
3. Who actually does the work?	A journeyperson, or an apprentice working under one	An unsupervised apprentice or a subcontractor you never meet
4. Do I get the price in writing before you start?	Yes, and the number holds	A ballpark, then a bigger invoice
5. Do you pull permits when the job needs them?	Yes, and they book the inspection	"You don't really need one for this"
6. Do you stand behind the work?	A clear answer on what happens if something is not right	No answer, or "call the manufacturer"
7. Will you tell me if I do not need the work?	Yes. Sometimes the right answer is no	Every visit ends in an upsell

Why the licence matters

Plumbing and gasfitting are compulsory certification trades in Alberta, which means the work has to be done by a certified journeyperson or a registered apprentice. Alberta's plumber training also includes Gasfitter Class B, so a fully certified plumber can handle your gas lines, furnace and water heater too. Here is how that credential works. You can check a certificate through Alberta's Tradesecrets site.

Why permits matter

In Calgary, plumbing and gas installations need permits, and the inspection is your independent check that the work meets code. Unpermitted plumbing hidden behind drywall can mean opening walls later when you sell or renovate. Simple repairs, like fixing a leak or swapping a faucet in the same spot, usually do not need one.

Why a written price matters

For anything beyond a simple service call, the price should be in writing before work starts, and it should say what is included. Comparing quotes only works when they cover the same scope. Here is how plumbing pricing works in Calgary.

Common questions

How do I check if a plumber is licensed in Alberta?

Ask for their full name and certificate, then check it through the Government of Alberta's Tradesecrets site.

Is a Red Seal plumber better?

Red Seal is the interprovincial standard on top of the Alberta journeyperson certificate. It shows the plumber passed the national exam for the trade.

Should I always get three quotes?

For larger jobs, comparing quotes is reasonable, as long as each one covers the same scope. For an urgent repair, a responsive licensed plumber matters more.
