Scarborough Windows & Doors handles every step in-house, from the first measurement to the final seal, so nothing gets lost between subcontractors. Homeowners across Scarborough, Ontario, call us for straight answers, fair pricing, and a crew that shows up when they say they will.
Scarborough Windows & Doors has been installing, repairing, and replacing windows and doors in this city for more than 22 years, growing from a two-person operation into one of the area’s most-reviewed installers. What hasn’t changed is who’s involved: the same family still oversees every job, and warranty work gets handled directly rather than passed off to a call center. Word of mouth carries most of the business forward: about seven in ten new jobs come from a referral, not an ad.
From a single cracked pane to a full door replacement, this is what we handle in Scarborough homes.

Every job runs through the same crew, from the person who measures your windows to the one who installs them and answers the phone if something needs a follow-up. Pricing is fixed before work starts, and the number on your written quote is the number on your invoice, no matter how the job unfolds once the crew is on-site.
Glass, frame, and labor are covered for life, and the coverage passes to whoever buys the house next.
Homeowners typically see heating costs drop by up to 40% after switching to our triple-pane units.
Our crews arrive early, protect your home, and finish the install before dinner in most cases.
No add-on fees once the crew is on-site, no upsells, no surprises on the invoice.
Send us a few details about your project and we'll follow up with a clear, itemized quote, not a ballpark guess. There's no obligation to book, and no pushy follow-up calls if you decide to wait.
The person who quotes your job is a member of our company. We measure everything on-site before recommending anything.
Choose your frame color, hardware, glass package, and door style from physical samples, not just a catalog photo.
Nothing comes off a shelf. Every window and door is manufactured to your exact measurements before it ever reaches your home.
Our crew handles the install, hauls away the old units, and leaves the work area cleaner than they found it.
Every window we install carries an ENERGY STAR rating built for our region’s climate zone, with triple-pane glass and an argon-filled gap that keeps the cold out and the heat in. Homeowners who switch from older single or double-pane windows often notice the difference within the first cold snap, both in comfort and in what shows up on the utility bill.
A soft credit check won’t touch your score, and most homeowners get a decision in under a minute. If you’re approved, terms stretch out as far as 144 months, so a full-home upgrade fits into a payment you’d barely notice next to a cable bill.
"We had eleven windows replaced before a cold snap hit. The crew worked straight through two days of rain without complaint and left every room spotless. Our bedroom used to ice up on the inside in January; that hasn't happened once this year."
Denise K., Agincourt
"Our front door had been dragging on the frame for a year and two other companies wanted to sell us a full replacement. Their technician adjusted the hinges and reset the strike plate in under an hour for a fraction of the price."
Tom P., Wexford
"The old patio slider was so stiff you needed both hands to open it. The new one glides with one finger and locks properly for the first time since we moved in. Clean install, no drywall damage."
Priya S., Guildwood
"One pane fogged up between the layers and looked awful from the street. They replaced just the glass unit instead of pushing a whole new window on us, and it matched the rest of the house perfectly."
Aaron D., Malvern
"We added a full-lite glass door to the back of the house to bring more light into the kitchen. The crew templated it twice before cutting anything, and the seal around the frame is airtight."
Michelle O., Cliffcrest
"Replaced our old steel entry door after a break-in attempt left the frame cracked. The new multi-point lock system and reinforced frame make it feel like a completely different house."
Ray H., Woburn

Still have questions? A real person picks up, never an automated bot. Here's the fastest way to reach us:
Yes. If a window or door was damaged by a storm, a fallen branch, or an attempted break-in, we can inspect the damage, document it with photos, and provide a detailed estimate that your insurance adjuster can work from. We've handled claims for cracked glass, bent frames, and forced entry damage across Scarborough and the rest of Toronto's east end. We won't file the claim for you, but we'll provide everything you need to support it and get the repair scheduled quickly once it's approved.
A lot of problems don't require a new window. Foggy glass usually means a failed seal, which can often be fixed by replacing just the glass unit. Stuck sashes and drafts are frequently a hardware or weatherstripping issue. Full replacement makes more sense when the frame itself is rotted, warped, or the window is decades old and inefficient. During your free quote, we'll tell you honestly which category your windows fall into instead of defaulting to the more expensive option.
We haul everything away as part of the job. Old windows, doors, frames, and any debris from the install get loaded up and removed before our crew leaves, so you're not stuck renting a bin or making a trip to the dump. Floors and walkways are also cleaned and vacuumed at the end of each day. The only thing left behind is the new window or door, sealed and ready to use.
For a door that won't lock, close, or has been damaged in a break-in, we prioritize same-day or next-day service whenever possible. Call the number above and describe the issue, and we'll give you a realistic window instead of a vague callback promise. For anything involving home security, like a compromised entry door, we treat it as urgent and adjust our schedule to get a technician out quickly.
We work with a small number of Canadian manufacturers we've vetted over years of installs, rather than whatever happens to be cheapest that month. All of our vinyl windows and steel or fiberglass doors are built for Ontario's climate, with options across several price points and style lines. We'll walk you through the specific products available for your project during your quote, including samples you can see and touch before deciding.
Very little maintenance is needed. Wipe down tracks and weatherstripping a couple of times a year to keep them free of dirt and debris, and check that weep holes on window sills stay clear so water can drain properly. Hinges and locking hardware on doors benefit from a drop of lubricant annually. If anything ever feels off, like a hinge sagging or a lock sticking, our lifetime warranty covers the fix, so there's no need to troubleshoot it yourself.
