Drywall and framing work is easy to get wrong in ways that don't show up until months later — a fastener pop after the first season of humidity changes, a fire-rated wall that wasn't actually built to spec, or a finish that looks fine under shop lights but shows every seam once you move in furniture and turn on real lamps. Hiring the right contractor up front is the single best way to avoid all three.
1. Confirm Licensing, Insurance & WSIB Coverage
Any contractor working in your home or business should carry liability insurance and WSIB (Workplace Safety and Insurance Board) coverage. This protects you from liability if a worker is injured on your property, and protects your home from being on the hook for damage caused during the work. Ask for proof — a legitimate contractor will provide it without hesitation.
2. Check Review Volume, Not Just Rating
A 5-star rating from three reviews tells you far less than a 4.7-star rating from 80 reviews. Look for contractors with a substantial, consistent review history on Google and HomeStars — Canada's largest contractor review platform, widely used across the GTA. Read a handful of the detailed reviews, not just the star average, and pay attention to how the contractor responds to any negative feedback.
3. Ask to See a Real Portfolio
A contractor who does quality finishing work should be able to show you photos of completed projects, ideally similar in scope to yours — a basement development if that's your project, a commercial fit-out if that's yours. Vague or stock-looking photos are a signal to ask more questions.
4. Get a Detailed, Itemized Quote — Not a Vague Estimate
A trustworthy quote breaks down material, labour, finish level, and scope clearly enough that you could hand it to a second contractor and get a comparable bid. Vague, single-line quotes ("drywall basement — $X") make it easy for change orders to appear later for work that should have been included from the start.
5. Get Multiple Bids — But Compare Scope, Not Just Price
The lowest bid is sometimes lower because it excludes fire-rated board, a lower finish level, or fewer coats of compound than a competing bid. When comparing quotes, confirm each contractor is pricing the same finish level, the same board type, and the same scope of prep and cleanup before comparing the bottom line.
6. Evaluate Communication Before You Sign Anything
How a contractor communicates during the quoting process is a strong predictor of how they'll communicate once the job is underway. Do they answer questions clearly? Do they explain their reasoning, or just give you a number? A contractor who takes the time to explain finish levels, insulation options, or scheduling constraints during the sales process is more likely to keep you informed once work begins.
7. Ask About Warranty
Workmanship warranties vary by contractor and scope of work. Ask specifically what's covered, for how long, and get it in writing as part of your project agreement — not as a verbal assurance.
Red Flags to Watch For
- Reluctance to provide proof of insurance or WSIB coverage.
- Pressure to sign same-day for a "discount," a common high-pressure sales tactic.
- Quotes with no breakdown of material, labour, or finish level.
- No fixed address or verifiable business history.
- Requests for full payment up front before any work begins.
Questions Worth Asking Before You Hire
- Can you provide proof of liability insurance and WSIB coverage?
- What finish level are you quoting, and why is that the right level for this room?
- Roughly how long will this project take, from start to final walkthrough?
- Who is my single point of contact if I have a question during the project?
- What does your warranty cover, and for how long?
A contractor who answers all five clearly and without hesitation has likely done this many times before — which is exactly who you want framing, insulating and finishing your walls.
