Drywall installation in Ontario costs $2 to $4 per square foot hung, taped, and finished in 2026, with sheets themselves running $14 to $20 in materials. Here's the per-sheet and per-square-foot math, what each finishing level means, per-room examples, and where DIY actually breaks even.
Drywall Cost Per Sheet and Per Square Foot
Two ways to price the same job — per sheet if you're estimating materials, per square foot of surface if you're comparing quotes. Our drywall and plastering team quotes per square foot, finished:
| Scope | 2026 Cost | What's Included |
|---|---|---|
| Materials only (4x8 half-inch sheet) | $14–$20/sheet | Board only; screws, tape, compound add $1.50–$2.50/sheet equivalent |
| Hang only (boarding) | $0.75–$1.50/sq ft | Sheets fastened to studs, cut-outs done |
| Tape and finish to Level 4 | $1.00–$1.75/sq ft | Taped seams, three coats, sanded paint-ready |
| Full install (hang + finish) | $2–$4/sq ft | Complete paint-ready walls and ceilings |
| Basement incl. framing and insulation | $4.50–$7.50/sq ft | Studs, batts, vapour barrier, board, finish |
Quick conversions: a 12x12 bedroom carries roughly 500 sq ft of wall and ceiling surface, so a full drywall job on it runs $800–$1,400. A typical 800 sq ft basement carries 2,300–2,700 sq ft of surface — $5,500–$10,000 finished.
Finishing Levels: What You're Actually Paying For
Drywall finishing is graded Level 0 through 5, and the level on your quote matters:
- Level 3: tape plus two coats — fine behind tile or heavy texture, not for paint.
- Level 4: the standard — three coats, sanded, ready for flat and eggshell paint. This is what a normal quote means.
- Level 5: full skim coat over everything, +$0.75–$1.25/sq ft. Worth it under raking light, gloss paint, or wall-washing pot lights, where Level 4 joints photograph through the paint.
What Affects Your Quote
- Ceiling height: 9-foot-plus walls and stairwells add 15–30% for staging and handling.
- Ceilings vs walls: ceiling board is slower and harder on the body — expect 20–30% more per square foot than walls.
- Board spec: moisture-resistant board for bathrooms, 5/8-inch Type X for garages and fire separations, and sound-rated assemblies for legal suites all price above standard half-inch.
- Access and occupied homes: furniture, floor protection, and dust containment in a lived-in house add real hours versus an empty build.
- Small-job minimums: most crews carry a $300–$600 minimum — patching one wall costs disproportionately more per foot than boarding a basement.
Repair vs New Board
Not every wall needs replacement. Cracks at seams, corner-bead damage, and doorknob holes are repairs — typically $300–$900 depending on count and finish matching — while water-stained, crumbling, or mould-affected board should come out. Our drywall repair cost guide covers the repair side in detail.
The judgment call is texture matching and paint blending: a perfect patch in the middle of a 20-year-old ceiling still shows unless the whole surface is repainted. When more than a third of a surface needs work, re-boarding or skimming the full surface usually looks better and costs little more.
DIY vs Hiring a Pro
Hanging board is achievable DIY — sheets are cheap, cuts are forgiving, and a helper plus a drywall lift handles ceilings. Budget your savings honestly though: boarding is only $0.75–$1.50/sq ft of the price. The money is in taping, and taping is a genuine trade skill.
A pro tapes a basement in three visits with feathered joints you'll never find; first-timers produce ridges, pocked screw heads, and corners that flash under paint, then spend three weekends sanding. Our honest recommendation after hundreds of basements: hang it yourself if you enjoy the work, hire the taping, and have our painting team or your roller follow a surface that's actually ready.
Ways to Save
- Buy 54-inch board for 9-foot walls — two horizontal sheets, one seam, less taping labour.
- Order delivery to the room, not the driveway. Boom-truck delivery ($100–$200) beats carrying 70-lb sheets around two corners and through a stairwell.
- Consolidate scope: boarding the basement, garage, and a repair list in one mobilization prices better than three separate visits.
- Standard board where code allows — spec moisture and fire-rated board where required (bathrooms, garages, suites), not everywhere.
- Finish to Level 4 except surfaces under raking light. Whole-house Level 5 is a luxury few rooms justify.

Frequently Asked Questions
How much does drywall installation cost per square foot in Ontario in 2026?
Between $2 and $4 per square foot hung, taped, and finished to Level 4. Hanging alone runs $0.75–$1.50/sq ft and taping/finishing $1.00–$1.75/sq ft. Basements including framing and insulation run $4.50–$7.50 per square foot.
How much does a sheet of drywall cost in 2026?
A standard 4x8 half-inch sheet runs $14–$20 in Ontario. Moisture-resistant, 5/8-inch Type X fire-rated, and sound-rated board run $20–$35 per sheet. Screws, tape, and compound add the equivalent of $1.50–$2.50 per sheet.
How much does it cost to drywall a 12x12 room?
A 12x12 bedroom carries roughly 500 sq ft of wall and ceiling surface, so a complete hang-and-finish job runs $800–$1,400 in 2026. Add $150–$400 if you want a Level 5 skim on the ceiling for pot lights or gloss paint.
What is Level 5 drywall finish and do I need it?
Level 5 adds a full skim coat over the entire surface (+$0.75–$1.25/sq ft) so joints and screw heads can't telegraph through paint. You need it under raking natural light, wall-washing pot lights, or dark/gloss paint. Level 4 is the correct standard everywhere else.
Can I hang drywall myself and hire out the taping?
Yes, and it's the smartest DIY split. Hanging is manageable with a helper and a rented lift, but taping is where the finish quality lives — pro tapers leave paint-ready surfaces in three visits that first-timers rarely match. You keep the labour savings without wearing the finish quality.
