What questions should I ask a drywall contractor before hiring them for a project in the GTA?

Before hiring a drywall contractor in the GTA, you should ask about their WSIB coverage, insurance, finish level, included scope of work, timeline, and how they handle dust containment and cleanup — these six areas separate professional operations from fly-by-night operators, and the answers will tell you everything you need to know about the quality you can expect. Taking 15 minutes to ask the right questions upfront can save you thousands of dollars and months of frustration.

"Do you carry WSIB coverage and can you provide a clearance certificate?" This is the most important question and should be asked first. The Workplace Safety and Insurance Board (WSIB) provides workplace injury coverage in Ontario. If an uninsured worker is injured on your property, you as the homeowner could be held liable for their medical costs and lost wages. A legitimate drywall contractor will provide their WSIB clearance certificate without hesitation. Any reluctance or excuse is a red flag. Verify the certificate directly through WSIB's online portal — it takes two minutes.

"Do you carry general liability insurance, and how much?" Separate from WSIB, general liability insurance covers damage to your property caused during the work — a dropped sheet cracking your hardwood floor, compound splashed on cabinetry, or a screw gun punching through a water pipe. Minimum $2 million coverage is standard for GTA contractors. Ask for a copy of their certificate of insurance and verify it's current.

"What finish level is included in your quote?" This is where the biggest pricing misunderstandings happen in GTA drywall projects. There are five standardized finish levels (Level 1 through Level 5), and the difference between a Level 4 finish (standard paint-ready) and a Level 5 finish (premium smooth for critical lighting) is significant in both cost and appearance. Level 4 runs $2.00-$3.50 per square foot, while Level 5 runs $3.00-$5.00 per square foot. If the quote just says "tape and finish" without specifying a level, you and the contractor may have very different expectations. For living rooms and bedrooms with large windows that cast raking light across walls, Level 5 is worth the premium — Level 4 imperfections will be visible in that lighting. For closets, basements, and areas that will receive texture, Level 3 or 4 is appropriate.

"What exactly is included in the price — and what isn't?" A drywall quote should clearly specify: materials (board type and thickness, compound, tape, corner bead), hanging, taping, finishing to a specified level, sanding, and primer. Common items that may or may not be included: material delivery ($50-$150), old drywall removal and disposal ($1.00-$2.50 per square foot), vapour barrier installation, insulation, dust protection for floors and furniture, and final cleanup. For a GTA basement finishing project quoted at $5,000-$12,000 for the drywall scope, the difference between a quote that includes removal and disposal versus one that doesn't can be $1,000-$3,000.

"What is your timeline, and how do you handle delays?" A professional GTA drywall contractor should give you a realistic timeline that accounts for drying time between coats (24 hours minimum for pre-mixed compound, less for setting compound), inspection scheduling if permits are involved, and their current workload. A typical single-room project takes 3-5 days; a full basement finish takes 1-3 weeks for the drywall scope. Be wary of contractors who promise unrealistically fast timelines — rushing drywall finishing produces poor results that will be visible for years.

"How do you handle dust containment and cleanup?" Drywall sanding generates enormous amounts of fine dust that infiltrates every corner of a home through HVAC ducts, under doors, and through any opening. Professional crews should seal off the work area with polyethylene sheeting, cover HVAC registers, and ideally use dust-free sanding systems with vacuum attachments. In GTA condos, building management often mandates dust barriers at the unit entrance. Ask whether cleanup is included in the price and what it covers.

Additional Questions Worth Asking

"Can you provide references from recent GTA projects?" Ask for 2-3 references from projects similar to yours, and actually call them. Ask the references specifically about the quality of the finishing, whether the contractor stayed on schedule, and how they handled any issues.

"Will you pull the building permit, or is that my responsibility?" For projects requiring permits (basement finishing, garage conversions, new walls), the contractor typically pulls the permit, but this should be explicitly agreed upon. Permit costs in the GTA range from $300-$1,000 depending on the municipality and project scope.

"Do you warranty your work?" A confident drywall contractor will offer at least a one-year warranty on finishing work, covering cracking, tape failure, and screw pops that result from workmanship rather than structural movement.

Getting multiple quotes (at least three) and asking these same questions to each contractor gives you a clear basis for comparison. The lowest price is rarely the best value in drywall work — finishing quality varies enormously between contractors, and poor finishing is visible every day for as long as you live in the home.
