New Builds and Heritage Renovations Across Markham
Markham's drywall demand comes from two distinct directions. In the north, new subdivision construction in Cornell, Wismer, and Box Grove is delivering thousands of new homes that each need complete drywall packages — boarding, taping, and finishing on builder timelines. These production builds require crews who can maintain consistent quality across multiple units without falling behind schedule. In established areas like Angus Glen, Rouge River Estates, and Markham Heritage Estates, larger custom homes demand more detailed work including higher ceilings, architectural ceiling treatments, and premium finish levels. Meanwhile, Unionville and Markham Village present a different challenge: heritage home renovations where new drywall must integrate seamlessly with existing plaster walls, original moulding profiles, and older construction methods. Our finishers have the experience to handle all three segments of Markham's market.
For General Contractors
Whether you're managing a production build in Cornell or a custom home in Angus Glen, we provide a streamlined drywall trade package under one contract. Boarding, taping, and finishing are coordinated by a single crew supervisor, so you have one point of contact for scheduling and quality. For builders managing multiple lots simultaneously, we can stagger crews across your units to keep closings on track. We also handle framing and insulation, giving you the option to bundle trades and reduce the coordination burden. Our $10M liability insurance and WSIB compliance are current on every project.

Our Process
1
Pre-Drywall Inspection
We review the framed structure room by room, checking that studs are plumb, headers are level, and blocking is in place for future fixtures. Insulation is examined for gaps, and we confirm each mechanical and electrical rough-in carries its passed inspection sticker. In Markham subdivision builds across Cornell and Wismer, we perform this review in coordination with the builder's schedule so any corrections happen before our material arrives.
Typical timeline: 1-2 hours2
Material Delivery & Layout
Boards are delivered and dispersed by room according to a cut list that accounts for ceiling height, window placement, and board type. Standard sheets go to interior walls, while moisture-resistant panels are set aside for bathrooms and laundry areas. On Markham production builds, material staging is timed so boards are placed the day before boarding starts, keeping the site clear for other trades until we are ready.
Typical timeline: 1 day3
Board Installation
Ceiling sheets go up first to establish level reference lines, followed by upper and lower wall panels. In Angus Glen and Rouge River Estates homes with 9- or 10-foot ceilings, we hang full-length sheets vertically on feature walls to minimize visible horizontal seams. For Markham townhouse developments, fire-rated Type X board is installed on party walls and inspected independently before adjacent rooms are boarded.
Typical timeline: 3-7 days4
First Coat (Taping)
Compound is spread along each joint and paper tape is embedded while the mud is still wet, creating a reinforced bond. Metal corner bead is nailed or crimped onto outside edges, and every screw depression receives its initial fill. In Unionville heritage renovations, we pay particular attention to transition joints where new board meets existing plaster, using flexible tape and setting compound to prevent cracking.
Typical timeline: 1-2 days5
Second & Third Coats
The second coat widens the joint to approximately 8 inches, and the third extends it to 12 inches with a fine taper at each edge. We sand lightly between coats to knock down any ridges before the next application. Across Markham's production subdivisions, our tapers rotate through multiple lots on a staggered schedule, applying coats in sequence so drying time is used productively rather than creating idle days.
Typical timeline: 4-6 days6
Final Inspection & Touch-Ups
Every surface is examined under angled work light to catch subtle blemishes — pinholes, edge lines, and screw dimples that would show through primer. Any imperfections are addressed with a skim of compound and fine-grit sanding. In Markham heritage homes, we also verify that the texture transition between old plaster and new board is seamless before signing off. The space is dust-free and paint-ready at handoff.
Typical timeline: 1 dayFrequently Asked Questions
How much does drywall cost in Markham?
Drywall installation in Markham typically costs $3.50-$6.00 per square foot for boarding, taping, and finishing. New home construction falls toward the lower end due to open access and efficient layouts, while renovation work with occupied spaces and existing finishes to match costs more. We provide free on-site estimates.
Do you work on new subdivision homes in Cornell and Wismer?
Yes, new subdivision drywall in Markham's growth areas is a core part of our business. We work with production builders to deliver complete drywall packages on tight closing schedules. Our crews are structured to move efficiently through multiple units while maintaining consistent Level 4 finishing quality.
Can you match plaster walls when renovating heritage homes in Unionville?
Yes, our finishers can blend new drywall with existing plaster surfaces in Unionville and Markham Village heritage homes. This includes matching wall thickness at transition points, replicating existing textures, and ensuring a seamless result that respects the home's original character.
How long does basement drywall take in Markham?
A typical basement finishing project takes 1-2 weeks from board installation through final sanding. Larger basements with separate bedrooms, bathrooms, and recreation areas may take closer to 2-3 weeks. We use moisture-resistant drywall where required by code or best practice for below-grade applications.
Do you handle fire-rated drywall for Markham townhouses?
Yes, fire-rated party wall assemblies are required between attached dwelling units under the [Ontario Building Code](https://www.ontario.ca/laws/regulation/120332). We install 1-hour and 2-hour fire-rated assemblies with the correct board types, fastener spacing, and joint treatment. These assemblies are inspected before adjacent trades proceed, so correct installation is critical to keeping your project on schedule.
