Scarborough's Multiplex and Renovation Boom
Scarborough is experiencing a construction surge driven by Toronto's multiplex bylaws, which now allow up to four units on most residential lots. Bungalow-to-duplex and bungalow-to-fourplex conversions are transforming neighborhoods from Guildwood to Woburn. These projects require complete drywall packages with fire-rated party walls between units — a core specialty of our crew. Beyond multiplexes, Scarborough has a large basement finishing market in Agincourt and Malvern, where homeowners are creating legal secondary suites. New townhouse developments in Rouge and Highland Creek also keep our crews busy with high-volume new-construction drywall. Whether it is a single basement suite or a 20-unit townhouse block, we bring the same Level 4 quality standard.

Our Process
Pre-Drywall Inspection
We walk the project checking stud condition, bracing, and layout against the permit drawings. On Scarborough multiplex conversions — especially bungalow-to-fourplex builds in Woburn and Guildwood — we verify that new party wall framing meets fire-separation specifications and that all plumbing, HVAC, and electrical rough-ins have their municipal sign-off before any board is delivered.
Typical timeline: 1-2 hoursMaterial Delivery & Layout
Board quantities are calculated from our take-off, including separate counts for Type X fire-rated sheets, moisture-resistant panels for below-grade areas, and standard board for general living spaces. In Scarborough's tight-lot multiplex projects, storage space is limited, so we schedule just-in-time delivery and stage material vertically inside the structure rather than stockpiling outside.
Typical timeline: 1 dayBoard Installation
Fire-rated party walls and ceiling assemblies are hung first and photographed for the inspector, since these separations must be approved before adjacent units can proceed. Standard interior walls and ceilings follow. In Agincourt and Malvern basement secondary suites, we use moisture-resistant board on exterior-facing walls and install standard panels elsewhere, cutting precisely around window wells and egress openings.
Typical timeline: 3-7 daysFirst Coat (Taping)
We bed paper tape into fresh compound on every joint and embed metal bead on outside corners for sharp, damage-resistant edges. Screw heads get their first coat of fill. For Scarborough duplex and triplex conversions where multiple units share the same construction timeline, our tapers sequence their work so compound in one unit cures while the next is being taped, keeping the project moving without idle waiting periods.
Typical timeline: 1-2 daysSecond & Third Coats
Each successive coat is spread wider and sanded between passes. The second application covers roughly 8 inches across the joint and the third extends to 12, creating an invisible taper. On Scarborough townhouse blocks in Rouge and Highland Creek, we maintain quality consistency across all units by having the same finishing crew handle an entire phase rather than rotating personnel between buildings.
Typical timeline: 4-6 daysFinal Inspection & Touch-Ups
Work lights positioned at a low angle expose any remaining ridges, pinholes, or shadow lines across the finished surface. Each imperfection is addressed with spot compound and 220-grit sanding. For legal basement apartments in Scarborough, we also confirm that fire-rated ceiling assemblies remain intact — no missed screw holes or unsealed penetrations — before delivering the space as paint-ready.
Typical timeline: 1 dayFrequently Asked Questions
How much does drywall installation cost in Scarborough?
Drywall installation in Scarborough typically costs $3.50-$6.00 per square foot for board and finish, depending on ceiling height, number of cuts, and finish level. Fire-rated assemblies and specialty boards cost more. We provide free, itemized estimates for every project.
Do you handle fire-rated drywall for multiplex conversions in Scarborough?
Yes. Multiplex conversions require fire-rated separations between dwelling units — typically 1-hour rated assemblies using Type X drywall. We install single and double-layer fire-rated walls and ceilings to meet [Ontario Building Code](https://www.ontario.ca/laws/regulation/120332) requirements.
How long does drywall take for a typical Scarborough basement finish?
A standard basement finish (800-1,200 square feet) takes approximately 7-10 working days from board installation through final sanding. This includes hanging, three coats of compound, and sanding to a paint-ready Level 4 finish.
Can you drywall my basement apartment to make it a legal secondary suite?
Yes. We install drywall for legal basement apartments in Scarborough, including fire-rated ceiling assemblies between floors and moisture-resistant board where required. We work with your permit drawings and coordinate with your other trades.
Do you provide framing and insulation as well, or just drywall?
We provide all three trades — framing, insulation, and drywall. Bundling these under one contract reduces coordination overhead, eliminates scheduling gaps between trades, and gives you a single point of contact from studs to paint-ready walls.
How much would it cost to drywall a 20x20 room?
A 20x20 room in Scarborough runs $1,800-$4,000 supplied and installed for hang-tape-finish to Level 4. The lower end is typical for an empty box with standard 8-foot ceilings; 9+ foot ceilings, soundproofing, or pot-light cutouts push higher. Boarding without taping drops to $700-$1,400.
How much to replace a 12x12 drywall ceiling?
Replacing a 12x12 ceiling in Scarborough runs $700-$1,600 for tear-out, board, tape, and Level 4 finish. Popcorn ceiling removal adds $1.50-$3.00 per square foot. Older Scarborough homes with stipple ceilings often need a second skim coat to fully smooth out, which adds to the price.
How much to drywall a 10x10 room?
A 10x10 room in Scarborough runs $1,000-$2,200 for hang-tape-finish to Level 4 with standard 8-foot ceilings. The same room as boarding-only is $400-$800. Bedroom-sized rooms with closets or jogged walls add labour relative to a clean rectangle.
Is there a cheaper option than drywall?
Cheaper alternatives include plywood or T1-11 panel wall, shiplap, and tongue-and-groove pine, all of which avoid taping labour. None match drywall on fire rating, so the OBC limits where they can be used in occupied dwellings - garages and outbuildings are the typical applications. Drywall remains the most cost-effective code-compliant interior surface for habitable rooms.
How many sheets of drywall for a 1500 sq ft house?
A 1500 sq ft house typically needs 100-140 sheets of 4x8 drywall (3,200-4,500 sq ft of board) to cover walls and ceilings. Rough rule of thumb: floor area x 3 to 3.5 = total board area. Add 10% waste for cuts and damaged sheets when ordering.
