Not every contractor is created equal. Here are the questions to ask, the red flags to watch for, and how to protect yourself before signing anything.
Hiring a renovation contractor is one of the largest financial decisions most homeowners make. The difference between a great contractor and a problematic one is not always obvious on the surface. Here is how to evaluate your options systematically — before you sign anything.
Verify Licensing and Insurance
In Alberta, general contractors do not require a provincial license, but they must carry liability insurance and ensure their workers are covered under WCB (Workers' Compensation Board). Always ask for proof of both. If a contractor is reluctant to provide these documents, that is your answer.
- Request a current Certificate of Insurance — it should name your address
- Confirm WCB clearance — you can verify online at wcb.ab.ca
- Check for any BBB complaints or negative Google reviews older than 6 months
- Ask for references from projects completed in the last 12 months
Get a Detailed Written Quote — Not a Ballpark
A professional contractor should provide a written quote that breaks down labour costs, material costs, and a projected timeline. Vague quotes ("somewhere between $20,000 and $40,000") are not quotes — they are placeholders that give the contractor room to escalate costs later. If a contractor cannot or will not provide a detailed quote, move on.
Red Flags to Watch For
- Asking for more than 25–30% deposit upfront
- No physical business address or only a PO box
- Reluctance to pull permits ("we can save time if we skip those")
- Pressure to decide immediately or "lock in" pricing
- No written contract or agreement
Understand What One Point of Contact Means
A full-service renovation contractor coordinates all trades — plumbing, electrical, framing, drywall, finishing — and gives you one person to communicate with throughout the project. This is very different from a contractor who sub-contracts everything and disappears, leaving you to field calls from three different tradespeople.
The cheapest quote rarely delivers the best value. Total cost of ownership — including callbacks, repairs, and your time — is what matters.
