Whitby-based egress window specialists, serving Scarborough homeowners with OBC-compliant installations, start to finish. One crew, one quote, no subcontractors.
No site visit required. We respond within 1 business day with a firm, written price.
Three services. One specialist crew. Every project handled from first cut to finished install — no general contractors, no third-party subs.
We cut a new opening through your Scarborough home's foundation wall, excavate the window well, install the window unit, and finish everything to OBC standard — inside and out.
Already have a basement window that's too small? We enlarge the existing opening to meet egress requirements — retaining the existing frame location while expanding the rough opening and well.
Replacing a failing, leaking, or inefficient basement window with a new unit — same opening size, new window. A clean, straightforward job when no sizing upgrade is needed.
Scarborough is one of Toronto's largest districts, built out largely with post-war brick bungalows, side-splits, and two-storey homes across neighbourhoods like Agincourt, Wexford, Bendale, Woburn, and Scarborough Village. Homes from the 1950s–1970s typically have narrow utility-grade basement windows (around 14" × 24") that fall well short of today's Ontario Building Code minimum for sleeping quarters.
As Scarborough's population grows and housing costs rise, basement suites have become one of the most effective ways Scarborough homeowners increase property value and generate rental income. But a basement bedroom is not legal for sleeping without an OBC-compliant egress window — the minimum 0.35 m² unobstructed opening that allows emergency exit and rescue access. Modpro installs exactly to that standard, which means every bedroom we service is a bedroom that can be legally rented or used.
As one of the GTA's most diverse and rental-dependent areas, Scarborough has enormous demand for legal basement apartments — and Toronto's 2023 multiplex reforms have made adding units easier than ever. Egress window installation is almost always the first step to bringing a basement bedroom up to code.
From your first message to a passed inspection — here's exactly how every Scarborough project runs.
Send us photos of your basement window location (inside and outside). We assess concrete wall thickness, joist direction, and excavation depth remotely and send you a firm, written price within one business day. No site visit needed upfront.
We book your Scarborough installation and handle everything: concrete cutting with a track-mounted wall saw, exterior excavation, window well installation, supply of the OBC-compliant window unit, and structural framing around the new opening.
We finish the interior framing, insulate around the new opening, and ensure the installation meets all Ontario Building Code requirements. Most of the construction mess is managed outside — your basement stays clean throughout.
Any basement window installation or enlargement that creates a new opening — or significantly increases an existing one — in a foundation wall requires a building permit from the City of Toronto (Toronto Building). This is not optional: an unpermitted egress window can create problems when selling your home and may not satisfy your insurance provider.
The Ontario Building Code (Division B, Part 9) governs all residential egress window requirements in Scarborough. The minimum unobstructed opening is 0.35 m² with no single dimension less than 380mm, and the window sill must be no higher than 1,000mm from the finished floor. Modpro installs to these exact specifications on every Scarborough project.
Most City of Toronto residential building permits for window work are processed within 2–4 weeks. We can advise you on what to include in your permit application and what the inspector will look for during the final review.

Common OBC-compliant window sizes installed in Scarborough: 30×36 casement and 44×36 sliding. Maximum recommended width is 48" — wider openings may require a structural engineer review.
In May 2023, Toronto City Council adopted a city-wide multiplex by-law permitting up to four dwelling units as-of-right on most residential lots — no rezoning, no public meeting, and no additional parking required. Combined with laneway suites (2019) and garden suites (2022), Scarborough homeowners now have more ways than ever to add legal, income-generating units.
The critical requirement for any basement bedroom used as sleeping quarters: an OBC-compliant egress window. Without one, the room cannot legally be used as a bedroom — which means it cannot be included in a rental unit and will not pass a building inspection.
Modpro installs egress windows specifically to meet the OBC requirements for suite compliance. Once your window is installed and framed, you'll have the inspection-ready finish needed for your City of Toronto building permit. With Toronto rental vacancy consistently under 2%, a legal basement suite in Scarborough typically rents for around $2,000 per month.

"We recently hired Modpro Egress Solutions for a window project and couldn't be happier with the results. From the initial quote to the final installation, everything was handled professionally. They explained the process clearly, showed up on time, and completed the job within the timeline they promised. Kirk and his team were respectful of our home, kept the work area clean, and the quality of the installation is outstanding."

The most common questions we hear from Scarborough homeowners before booking.
Most egress window installations in Scarborough range from $2,750 to $4,000 for a single window. The main pricing factors are concrete wall thickness (standard poured or block vs. thick stone foundation), joist direction relative to the opening, and excavation depth. We provide firm, written quotes based on your photos, with inclusions and exclusions stated clearly.
Yes. The City of Toronto (Toronto Building) requires a permit any time you are creating a new opening or significantly enlarging an existing one in a foundation wall. This is standard across all Ontario municipalities. Unpermitted work can cause issues at sale and may void your home insurance. Most straightforward residential window permits in Scarborough are processed within 2–4 weeks. We can advise you on what to submit.
The Ontario Building Code requires a minimum unobstructed opening area of 0.35 m², with no single dimension less than 380mm, and a maximum sill height of 1,000mm from the finished floor (or 1,500mm with a permanently installed step). Common compliant window sizes we install in Scarborough: 30×36 casement and 44×36 slider.
Most single-window installations are completed in 2–4 days. Multi-window projects or jobs with deeper excavation typically run 3–5 days. The timeline depends on soil conditions, wall thickness, and joist direction. 99% of the construction mess is kept outside — your interior disruption is minimal throughout the project.
Yes. In Scarborough, up to four units are now permitted as-of-right under Toronto's 2023 multiplex by-law (subject to zoning). Any room used as sleeping quarters in a basement suite requires an OBC-compliant egress window. We install exactly to that standard — giving you the foundation you need for a legal suite. We handle the window work; the City of Toronto can guide you on the full registration process.

Scarborough is the easternmost district of the City of Toronto, home to roughly 630,000 residents across neighbourhoods such as Agincourt, Malvern, Guildwood, West Hill, Highland Creek, and Birch Cliff. Much of its housing is post-war (1950s–1970s) single-detached brick bungalows and side-splits on generous lots — ideal candidates for a basement suite, but almost always fitted with undersized utility-grade basement windows.
Scarborough is one of Canada's most diverse communities and a major rental market. Toronto's 2023 as-of-right multiplex reforms have accelerated basement-suite and multiplex conversions across the district — and egress window installation is central to bringing those units up to code.
Modpro is based in Whitby, just east of Scarborough along the 401, and regularly serves the eastern GTA. We're typically able to schedule Scarborough projects within a few days of quote approval.
