How much does a full sheet of half-inch drywall cost at Home Depot or a GTA building supply yard?

A standard 4x8 sheet of 1/2-inch drywall costs $14–$20 at Home Depot, Lowe's, and GTA building supply yards as of 2025–2026, with the exact price depending on the brand, whether it is regular or lightweight, and whether you are buying individual sheets or in volume. At Home Depot specifically, a CGC Sheetrock standard 1/2-inch 4x8 sheet typically sits around $15–$18, while their CertainTeed equivalent runs a similar price.

The price per sheet changes depending on what type of 1/2-inch board you need. Regular standard 1/2-inch (the most common board for interior walls) runs $14–$20. Lightweight 1/2-inch (brands like CGC Ultralight or CertainTeed EasiLite) costs $18–$24 — the $4–$6 premium buys you a board that weighs 25–30% less, which matters significantly for ceiling work and carrying sheets through tight spaces. Moisture-resistant 1/2-inch (green board) runs $20–$28, and mould-resistant 1/2-inch (purple board) with fibreglass facing costs $24–$32.

Sheet size also affects your per-unit cost. Most homeowners think of drywall as 4x8 sheets, but professional drywall crews in the GTA almost always use longer sheets — 4x10 and 4x12 — because longer sheets mean fewer joints, which means less taping, less finishing, and a better-looking result. A 4x12 sheet of standard 1/2-inch drywall runs $22–$30 at GTA supply stores. While the per-sheet cost is higher, the per-square-foot cost is comparable, and the labour savings from fewer joints are substantial. For a basement finishing project, using 4x12 sheets on long walls can eliminate dozens of butt joints that would otherwise need careful finishing.

Volume pricing makes a significant difference. Home Depot and Lowe's offer modest discounts on bulk purchases — typically 5–10% off when buying 50+ sheets, with some locations offering better pricing on full-skid quantities (a skid typically holds 40–60 sheets depending on thickness). However, dedicated building supply yards like WINROC, Turkstra Lumber, Castle Building Centres, and independent GTA suppliers typically offer better volume pricing than big-box stores. At contractor supply yards, volume pricing on standard 1/2-inch can drop to $12–$16 per 4x8 sheet for orders of 100+ sheets. If you are tackling a full basement or a multi-room renovation, it is worth calling two or three local supply yards for quotes before defaulting to Home Depot.

Beyond the per-sheet price, factor in these additional costs. Delivery fees range from $50–$150 depending on the supplier, the quantity ordered, and your location within the GTA. Most suppliers offer free delivery on orders over $500–$1,000. If you need the drywall placed inside your home rather than just dropped at the curb, expect to pay an additional $100–$200 for interior placement or boom-truck delivery (where a hydraulic arm lifts the drywall through an upper-floor window or into a specific room). Drywall is heavy — a standard 4x8 sheet of 1/2-inch weighs about 57 pounds — and a full basement project requiring 80–100 sheets means managing over two tonnes of material. Professional delivery and placement is money well spent.

A quick cost estimate for a common project: finishing an 800-square-foot GTA basement with 8-foot ceilings requires approximately 75–90 sheets of 1/2-inch drywall (walls and ceiling combined), plus 8–12 sheets of 5/8-inch Type X for the furnace room fire separation. At retail pricing, that is roughly $1,200–$1,800 for boards alone. Add $100–$200 for joint compound (4–6 boxes), $20–$40 for tape, $30–$50 for screws, $20–$40 for corner bead, and $50–$150 for delivery. Total material cost for drywall scope: approximately $1,500–$2,300. Labour for professional hanging and finishing typically adds another $3,500–$8,000 depending on the finish level and complexity.
