Finding a Trusted Windows & Doors Contractor in Scarborough
Scarborough's housing stock ranges from 1960s and '70s brick bungalows and sidesplits in Wexford, Woburn, and Scarborough Village to newer townhomes near Agincourt and condo-adjacent infill around Kennedy and Eglinton. Many of the older homes still carry original single-pane aluminum-frame windows and steel entry doors that have never been replaced, making energy loss and drafts a common complaint during Scarborough's humid summers and cold, wind-exposed winters off the lake.
Because Scarborough sits within the City of Toronto's jurisdiction, window and door replacements that don't alter the size of an opening generally don't require a building permit, but enlarging a window or adding a new patio door opening does — homeowners should confirm with Toronto Building before work starts. Contractors working on older homes here also need to be comfortable with brick veneer construction, aluminum siding, and the deeper wall cavities typical of postwar builds.
At this time, GTA Trades Daily has no verified contractors listed for Windows & Doors in Scarborough. We vet local tradespeople for insurance, WSIB coverage, and manufacturer certifications before listing them, so check back as we onboard companies serving this area. In the meantime, use the cost and FAQ information below to understand what fair pricing and scope look like for Scarborough properties before you start collecting quotes.
Across the GTA, single window replacements typically run $600–$1500 per window depending on size, frame material, and glazing; entry door installation ranges $1200–$3500 including hardware and weatherstripping; and patio or sliding door installation runs $1500–$4000. In Scarborough specifically, expect costs to trend toward the middle-to-upper end of these ranges for older brick bungalows and sidesplits where original openings have settled or are non-standard sizes, requiring custom framing rather than off-the-shelf replacement units. Homes with aluminum cladding or added exterior brick veneer may also need extra flashing and trim work, which can add to labour time. Newer townhomes in areas like Agincourt or Milliken tend to have standard-sized openings, keeping quotes closer to the lower end of each range.

Frequently Asked Questions
Do I need a permit to replace windows or doors in my Scarborough home?
If you're replacing a window or door within the same opening size, Toronto Building generally does not require a permit. However, if you're enlarging an opening, adding a new patio door where none existed, or altering a structural header, a permit is required. Since Scarborough falls under the City of Toronto's building code jurisdiction, it's worth a quick call to Toronto Building to confirm before work begins.
Are older Scarborough homes with aluminum-frame windows harder to replace?
Many Scarborough bungalows and sidesplits built in the 1960s and '70s still have original aluminum-frame single-pane windows. These openings are often non-standard sizes and set into brick veneer, so installers typically need to do custom measurements and additional flashing work rather than using stock vinyl replacement units. This can add labour time compared to a straightforward swap in a newer home.
What should I look for in an entry door installer for a Scarborough bungalow?
Look for an installer experienced with older masonry openings, since many Scarborough entry doors sit in brick or concrete block walls with settled frames. Confirm they carry WSIB coverage and general liability insurance, and ask whether the door unit and installation come with a written warranty, since exposure to lake-effect wind and winter freeze-thaw cycles can stress poorly sealed installations over time.
