Hiring a general contractor is one of the bigger financial decisions a homeowner makes — and one of the easiest to get wrong. A good contractor makes a renovation feel manageable; a bad one turns it into months of stress, surprise costs, and work you'd never show a neighbour. Here's how to tell the difference before you sign anything.
1. Can I see your recent local work — and talk to those clients?
References are non-negotiable. Ask for recent projects in Barrie or Simcoe County, ideally similar in scope to yours, and actually call the homeowners. Ask them: did the crew show up when promised? How were surprises handled? Would you hire them again? A contractor with nothing to hide will hand over names happily.
2. Will I get a detailed written quote — not just a number?
A proper quote breaks the project into line items: scope of work, materials, labour, and what's explicitly excluded. Vague one-line quotes ("renovate bathroom — $18,000") are where disputes are born. The written scope protects both sides: you know exactly what you're paying for, and the contractor has a clear definition of done. No written contract, no deal.
3. Who is actually doing the work?
Some contractors sell the job and send whoever's available. Ask who will be on site day to day, whether they use their own crew or subcontractors, and who supervises. You want to know the name of the person accountable for your project — and you want to meet them before work starts, not after.
4. How do you handle change orders?
Nearly every renovation encounters something unexpected behind a wall. What matters is the process: changes should be documented in writing, priced before the work happens, and signed off by you — not sprung on you in the final invoice. Ask how they've handled surprises on past jobs; the answer tells you everything about how they'll treat you.
5. What's the realistic timeline — and what happens if it slips?
Ask for a schedule with milestones, not just a start date and a shrug. Then ask what typically causes delays on their projects and how they communicate them. Delays happen in construction; the difference is whether you hear about them in advance with a plan, or discover them when nobody shows up on Monday.
6. How do you handle permits and inspections?
Your contractor should pull the required permits and schedule inspections as a matter of routine — not treat them as optional or your problem. Unpermitted work can void insurance, kill a future sale, and cost far more to fix retroactively than the permit ever would.
7. What does cleanup and warranty look like?
A professional job includes a broom-clean site at the end of each day and a thorough cleanup at the end of the project — not dust in every room and a dumpster in your driveway for a month. And ask about warranty: what do they stand behind, for how long, and in writing? The answer (or the dodge) is revealing.
Red Flags That Should Stop You Cold
Walk away from: quotes dramatically lower than everyone else's (the money comes out somewhere — usually in shortcuts or surprise extras), pressure to sign today, cash-only demands with no receipt, no fixed business address, and anyone who badmouths every previous client they've had. Trust your gut — if the sales process feels off, the project will feel worse.
The Bottom Line
The cheapest quote is rarely the best value, and the smoothest talker isn't always the best builder. Choose the contractor who gives you specifics in writing, answers hard questions directly, and treats your home like it's their reputation on the line — because it is.
