What we replace in Scarborough homes
Replacement windows
Most calls we get from Agincourt, Wexford, Bendale and Guildwood are for houses built between 1955 and 1975. The original wood or aluminum sliders are single-pane, the sashes stick, and the frames have been painted so many times they no longer seal. We measure every opening, build to size, and install full-frame or retrofit depending on what the brick and sill will allow.
Entry doors
Insulated steel or fibreglass, with the frame and threshold replaced at the same time. On older Scarborough bungalows the door is often out of square with the jamb. We re-hang it properly rather than forcing a new slab into an old frame.
Eavestrough and downspouts
Five-inch seamless aluminum, formed on site to the length of the fascia. If the existing downspouts dump water beside the foundation, we move them. On the clay soil under most of Scarborough, that is where basement leaks start.
Basement egress windows
Cutting a larger opening in a block or poured foundation for a legal bedroom or basement apartment. This needs a City of Toronto building permit, and we handle the drawings and the application.
Patio doors
Sliding and garden doors for backyard walkouts. A lot of Scarborough houses still have the original 1970s aluminum slider. The replacement is a vinyl frame with a low-E, argon-filled sealed unit and a proper drip cap above it.
Why Scarborough homeowners call Fortress
We are the window company that is actually in Scarborough. Our office is at 4725 Sheppard Ave E, Unit 405, and our installers come to your house from here, not from a showroom on the other side of the 401. If something needs a second look after the install, we are ten minutes away.
Installing since 1989
Fortress has installed windows and doors across the east end of the GTA for 37 years. Family-owned, still run by the family.
HomeStars winner every year since 2014
That comes from customer reviews, not a paid badge. Read them before you call us.
Canadian-made, CSA certified, Energy Star
The windows we install are built in Ontario, certified to CSA A440 and Energy Star rated for Canada.
Licensed, insured, and we pull the permits
When a job needs a City of Toronto permit, such as an egress window or an enlarged opening, we file it. You will never be asked to sign off on unpermitted structural work.
Financing available
Flexible financing on windows and doors, so a whole-house replacement does not have to wait for one big cheque.

- Removal and disposal of the old windows and doors
- Foam insulation around every frame
- Colour-matched exterior aluminum capping

Service Steps
1. Call or book a measure
Tell us what you are looking at replacing and roughly when. Call (416) 291-5795 or use the quote form.
2. In-home measure
We measure every opening, check for rot or water damage, and go through frame colour, grilles and glass options at your kitchen table.
3. One written price
A single price for the whole job. It does not change unless you change the scope.
4. Build and install
Windows are custom-built to your measurements, which takes a few weeks and longer in the spring rush. Most single-family homes in Scarborough are installed in one to two days.
5. Walk-through and warranty
We walk every window and door with you, show you how the hardware works, and register your warranty.

What changes after the install
Lower heating bills
A single-pane 1960s window loses several times the heat of a modern low-E, argon-filled unit. In a Scarborough bungalow with 12 to 15 windows, that shows up on the Enbridge bill the first winter.
No more cold spot by the window
The cold pocket in front of the living room window in January is the frame leaking, not the glass. Foam-insulated frames fix it.
A quieter house
Sealed double or triple glazing cuts traffic noise noticeably. Worth it near Kingston Rd, Sheppard or the 401.
Rebates when they are open
Ontario and federal energy rebate programs come and go. We track what is open when you book and tell you what your job qualifies for.
Fewer basement problems
Properly pitched eavestrough with downspouts extended away from the wall keeps water off the foundation. On clay soil that is the cheapest basement waterproofing you will ever buy.
Easier resale
Home inspectors look at the windows first. New, warrantied windows go in the listing. Forty-year-old aluminum sliders come up in the negotiation.

Frequently Asked Questions
Do I need a permit to replace windows in Scarborough?
Not for a like-for-like replacement in the same opening. You do need a City of Toronto building permit if the opening is being enlarged or a new one is being cut, which is the case for most basement egress windows. We prepare and file the permit as part of the job.
How long does window replacement take?
A typical Scarborough house with 10 to 15 windows is installed in one to two days once the windows arrive. Lead time from measure to install depends on the season; spring and early fall are the busiest.
Do you replace windows in winter?
Yes. We do one opening at a time so the house is never open for long, and the foam and caulking we use are rated for cold-weather application. Winter is often the quickest time to get on the schedule.
