Drywall Cost Breakdown: Where Every Dollar Actually Goes

Why a $6,000 basement job is not a $6,000 basement job

"Drywall installation cost" is not one number — it is a stack of materials, labour, finishing, primer, dust control, and overhead. When you understand the stack, you can compare quotes properly and ask the right questions. For top-line numbers, our installation cost page and taping cost page have the per-square-foot ranges.

Below is a real-world breakdown of a typical 1,200 sq ft GTA basement drywall project — the kind of job we do every week in Mississauga, Brampton, and Vaughan. The total is $5,800. Here is where it goes.

Materials — about 28% of the total ($1,624)

• Drywall sheets: 64 sheets × $17 average = $1,088
• Joint compound: 6 buckets × $25 = $150
• Tape: 6 rolls paper tape = $30
• Corner bead: 12 lengths metal/paper-faced = $84
• Screws: 4 boxes coarse-thread = $52
• Drywall primer (PVA): 5 gallons = $185
• Sandpaper, mesh sanding screens, knives: $35
• Dust-control mud upgrade: $0 (already in the standard mud line)

Materials are roughly 25–35% of any residential drywall job. If the contractor is buying low-grade off-brand sheets, they save money — and you get inconsistent thickness, brittle paper face, and harder-to-tape seams. We buy major-brand consistently for both residential and commercial jobs. (More on choosing the right board in our drywall thickness guide.)

Labour — about 56% of the total ($3,248)

Labour is the biggest single line. For a 1,200 sq ft basement:

• Hanging: 2 days × 2 tapers × 8 hours × $55/hr blended rate = $1,760
• Tape coat: 1 day × 2 tapers × $55 × 8 hours = $880
• Fill coat (next day): roughly half a day = $440
• Finish coat (next day): roughly quarter day plus sanding = $168

The hourly blended rate covers the apprentice rate, the lead taper rate, payroll taxes, WSIB, vacation accrual, and benefits. The sticker rate to the customer ($55/hr in this example) is not what the taper takes home — it is what the company's books pay before overhead.

Vehicle and equipment — about 4% ($232)

• Truck and gas: $80
• Drywall lift rental (if used): $60
• Tools (depreciation): $30
• Drop sheets, dust barriers, zip wall: $62

Insurance and overhead — about 6% ($348)

$5M general liability premiums, WSIB premiums, accountant fees, insurance claims reserve, vehicle insurance, software, and administration time. This is the cost of running a real business — and it is what separates a fly-by-night cash crew from a contractor who can warranty their work and stand behind it.

Overhead and margin — about 6% ($348)

Office costs, marketing, management time, and the company's profit. This is what allows the company to invest in better tools, training, and crews — and what funds the warranty reserve when a tape lifts a year later and we have to come back free.

Why "cash discount" never adds up

If a contractor offers a "cash discount" of 13% — about $750 on a $5,800 job — they are usually skipping HST collection, dropping insurance compliance, or paying labour off-the-books. Any of those mean: no warranty, no recourse if things go wrong, no insurance if a worker is injured at your home, and personal liability you do not want. The savings disappear if anything goes wrong. Our hiring guide covers the other red flags worth watching for.

Where to actually save money

• Hang it yourself. If you are handy and have help, hanging drywall is the easy part. Pay a pro for taping only — saves 35–45% off a hang-and-tape number.
• Skip Level 5 in non-critical rooms. Closets, hallways, mechanical rooms — Level 4 is plenty. (Our taping levels post covers where to invest the extra money.)
• Stage jobs. Doing a basement now and an addition next year, with the same crew, gives the contractor scheduling certainty and they can sometimes price better.
• Be ready when the crew arrives. Empty rooms, removed trim, completed framing, accessible electrical — every hour the crew waits is an hour billed.
• Bundle related trades. If your contractor recommends a painter and a flooring company they trust, the scheduling overhead drops and total project cost is usually lower than three independently-managed contractors.

Where you should not save money

• Insurance and licensing.
• Materials grade.
• Number of mud coats.
• Warranty.
• Final clean-up.

Drywall is one of those trades where the difference between a great job and a bad job is invisible until the lights are right and the paint is on — and at that point the cost of fixing it is easily 3× the cost of getting it right the first time.
