Scarborough is experiencing a construction surge driven by Toronto's multiplex by-laws, with bungalow-to-fourplex conversions requiring fire-rated party walls across neighborhoods from Guildwood to Woburn. Konstruction Group provides complete drywall services throughout Scarborough — board installation, taping, and finishing to Level 4 — plus framing and insulation under one contract.
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.
We work with general contractors across Scarborough on projects ranging from single-home renovations to multi-unit residential builds. Our crews are experienced with the scheduling demands of multiplex and townhouse projects — we coordinate around mechanical, electrical, and plumbing rough-ins and deliver paint-ready walls on your timeline. We carry $10M liability insurance and full WSIB coverage, so your job site stays compliant. One call covers framing, insulation, and drywall.
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 hoursBoard 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 dayFire-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 daysWe 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 daysEach 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 daysWork 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 dayDrywall 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.
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.
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.
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.
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.
