Question 1

Where can I buy fire-rated Type X drywall in the Toronto area and how much does it cost per sheet?

Accepted Answer

Fire-rated Type X drywall is widely available across the GTA from both big-box retailers and specialty drywall suppliers, with pricing running $20–$28 per 4x8 sheet for standard 5/8-inch Type X. This is one of the most commonly stocked drywall products in the Toronto market because every attached garage, furnace room, and multi-unit fire separation in Ontario requires it.

Question 2

What is the shelf life of drywall compound and how should it be stored through a Toronto winter?

Accepted Answer

Pre-mixed drywall joint compound has a shelf life of approximately 9–12 months from the date of manufacture when stored properly, but Toronto's winter climate is the single biggest threat to its usability. If compound freezes even once, it is ruined — the emulsion breaks down permanently, leaving a lumpy, grainy texture that will not spread smoothly and will not bond properly to tape or drywall. There is no way to restore frozen compound, and using it will result in cracking, poor adhesion, and

Question 3

What type of drywall screws should I use for different applications in a Toronto home renovation?

Accepted Answer

The right drywall screw depends on two things: the thickness of the drywall board and what you are screwing into (wood framing or steel studs). Using the wrong screw is one of the most common DIY mistakes in GTA renovations, and it leads to screw pops, loose boards, and cracked joints that show through paint — problems that are expensive to fix after the fact.

For the vast majority of residential drywall work in Toronto homes, you are dealing with wood framing and need coarse-thread drywall scr

Question 4

How much joint compound and tape should I buy per sheet of drywall for a GTA residential project?

Accepted Answer

As a reliable rule of thumb for GTA residential projects, plan on roughly one 17-litre box of pre-mixed joint compound for every 8–10 sheets of drywall, and one 75-metre roll of paper tape for every 10–12 sheets. These ratios assume standard three-coat finishing (bedding coat, fill coat, finish coat) on walls and ceilings with a Level 4 paint-ready result, which is what most Toronto-area residential renovations require.

Question 5

What drywall accessories and supplies should I buy before starting a basement finishing project in the GTA?

Accepted Answer

Before starting a basement finishing project in the GTA, you need a comprehensive materials list that goes well beyond just drywall sheets — the accessories and supplies are what determine whether your finished basement walls and ceilings look professional or amateur. A typical 800–1,200 square foot basement finish will require a substantial materials investment, and having everything on hand before the crew starts (or before you start, if you are tackling portions yourself) prevents costly dela

Question 6

Are there GTA suppliers that sell reclaimed or surplus drywall at a discount for budget-friendly renovations?

Accepted Answer

Reclaimed or surplus drywall is available in the GTA, but it comes with significant limitations that homeowners need to understand before banking on it for a renovation budget. The drywall market in Toronto does include surplus, overstock, and seconds channels, but the savings are modest compared to the risks, and the supply is inconsistent.

The most reliable source of discounted drywall in the GTA is surplus and overstock from large construction projects. When condo towers, commercial builds,

Question 7

What thickness and type of drywall should I buy for a garage ceiling in an Etobicoke home?

Accepted Answer

For a garage ceiling in an Etobicoke home, you need 5/8-inch Type X fire-rated drywall — this is not optional, it is required by the Ontario Building Code. The wall and ceiling assembly between an attached garage and the living space above must achieve a minimum 45-minute fire resistance rating, and standard 1/2-inch regular drywall does not meet this requirement. Type X drywall has a glass-fibre reinforced gypsum core that holds together under fire conditions long enough to allow occupants to e

Question 8

How much does moisture-resistant drywall cost compared to regular drywall at Toronto-area suppliers?

Accepted Answer

Moisture-resistant drywall costs roughly 40–60% more than regular drywall at Toronto-area suppliers, with the price gap widening further if you step up to mould-resistant board. Standard 1/2-inch regular drywall runs $14–$20 per 4x8 sheet in the GTA, while moisture-resistant green board (same 1/2-inch thickness) costs $20–$28 per sheet, and premium mould-resistant purple board with fibreglass facing runs $24–$32 per sheet.

The price difference is significant when you are boarding an entire base

Question 9

Do GTA building supply stores deliver drywall sheets to residential homes and what are the typical delivery fees?

Accepted Answer

Yes, virtually all GTA building supply stores deliver drywall to residential homes, and delivery fees typically range from $50 to $200 depending on the quantity ordered, your location within the GTA, and whether you need basic curbside drop-off or interior placement. Most suppliers offer free delivery on orders above $500–$1,000, which is easily reached on any project requiring more than 25–30 sheets of drywall.

Home Depot offers delivery across the GTA with fees starting around $79 for standar

Question 10

Where can I find specialty drywall products like flexible sheets and curved corner bead in the GTA?

Accepted Answer

Specialty drywall products like flexible drywall sheets, curved corner bead, and custom moulding profiles are available at dedicated drywall supply distributors in the GTA — primarily WINROC Distribution, specialty divisions of major building supply yards, and select Home Depot and Home Hardware Building Centre locations that carry expanded drywall lines. Big-box stores stock the basics, but for specialty and professional-grade products, you will almost always need to visit or order from a drywa

Question 11

How do I calculate exactly how many sheets of drywall I need for a Toronto basement renovation with minimal waste?

Accepted Answer

To calculate your drywall sheet count accurately, measure every wall and ceiling surface in square feet, subtract door and window openings, add a 10–15% waste factor, and then divide by the sheet size you plan to use (32 sq ft for 4x8, 40 sq ft for 4x10, or 48 sq ft for 4x12). Getting this calculation right saves money on materials and avoids the frustrating mid-project trip back to the supply yard — or worse, having 20 leftover sheets you cannot return.

Start by measuring every wall that will

Question 12

What is the difference between green board, purple board, and standard white drywall for GTA bathroom use?

Accepted Answer

Standard white drywall should never be used in GTA bathrooms, green board (moisture-resistant) is the minimum acceptable choice for bathroom walls not in direct water contact, and purple board (mould-resistant) is the superior option that most experienced Toronto drywall contractors now recommend for all bathroom applications. Understanding the differences between these three products can save you from a mould disaster that is all too common in GTA bathrooms.

Standard white drywall has a paper

Question 13

Which drywall brands are most commonly used and recommended by Toronto contractors?

Accepted Answer

CGC (Canadian Gypsum Company, a subsidiary of USG) is overwhelmingly the dominant drywall brand used by Toronto contractors, followed by CertainTeed and Georgia-Pacific. If you ask ten GTA drywall contractors what they hang, at least seven or eight will say CGC — it is the Canadian standard, widely stocked at every supply yard in the region, and its joint compounds (particularly CGC Sheetrock brand) are the industry benchmark for finishing.

CGC Sheetrock is the most widely available and commonl

Question 14

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

Accepted Answer

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

Question 15

What type of drywall compound works best in Toronto's humid summer conditions for taping and finishing?

Accepted Answer

Setting-type compound (commonly called "hot mud") is the best choice for drywall taping and finishing during Toronto's humid summer months, because it cures by chemical reaction rather than evaporation and is therefore far less affected by high humidity. Pre-mixed all-purpose and topping compounds rely entirely on moisture evaporating from the compound into the surrounding air — and when that air is already saturated with humidity during a GTA summer, drying times can double or triple, delaying

Question 16

Where can I buy large quantities of drywall sheets at contractor pricing in the Greater Toronto Area?

Accepted Answer

For large-quantity drywall purchases at contractor pricing in the GTA, your best options are dedicated building material suppliers like CGC distributors, WINROC (now part of the Superior Plus network), and independent drywall supply yards rather than big-box retail stores. These suppliers offer volume pricing that can save you 20–40% compared to retail pricing at Home Depot or Lowe's, and they typically stock a wider selection of board sizes, types, and specialty products.

Question 17

What is the price difference between regular and lightweight drywall at GTA building supply stores?

Accepted Answer

Lightweight drywall typically costs $4–$6 more per 4x8 sheet than standard regular drywall in the GTA, with regular 1/2-inch boards running $14–$20 per sheet and lightweight 1/2-inch boards running $18–$24 per sheet. Whether the premium is worth it depends on where the board is going, who is installing it, and the specific challenges of your project.

Lightweight drywall — sold under brand names like CGC Ultralight and CertainTeed EasiLite — weighs 25–30% less than standard drywall. A regular 4x
