Custom Windows & Doors Scarborough builds every unit in Canada and installs it with our own crew, never a subcontractor. Homeowners across Scarborough, Ontario, have counted on us for 22+ years, backed by a lifetime transferable warranty on every project.
We started as a small team replacing windows and doors, and the basic approach hasn’t changed since: measure carefully, build to the exact opening, and install it ourselves. Twenty-two years later, that’s still how every job runs, whether it’s one window or a full retrofit.
We don’t sell a product we wouldn’t be comfortable installing ourselves, and we don’t hand the job to whichever crew is available that week. Every unit is custom-built and every install is done by our own team, backed by a lifetime workmanship warranty.
Whether you're replacing one drafty window or re-glassing the whole house, the same team measures, builds, and installs it, start to finish.

Every one of these comes down to how we actually run the business, not just what we say in a quote.
We've held an A+ rating with the Better Business Bureau for years, the kind of track record that only holds up if complaints get resolved, not filed away.
Every technician in your home is covered by liability insurance and WSIB, so if anything goes sideways on the job, it's on us, not you.
If a repair will genuinely fix the problem, we'll say so instead of quoting a full replacement, even though the smaller job is worth less to us.
You'll get a message when the crew is on the way and another when the job's done, so you're never wondering what's happening at your own house.
Describe your project and we'll get back to you with a straightforward, written price, not a range, not a placeholder, and not a reason to call you five times afterward.
Someone from our team comes out, takes real measurements of every opening, and talks through what actually makes sense for your home, no scripted pitch involved.
Frame colors, hardware finishes, grille patterns, and glass packages, laid out with actual samples in hand rather than a screen.
Nothing comes off a shelf. Your exact specs go to the plant, with production typically wrapping in three to five weeks.
The crew shows up on schedule, works through the list methodically, and leaves your home in the same condition they found it, minus the old windows.
Every window we install is ENERGY STAR® certified for our climate zone, with triple-pane Low-E argon glass standard rather than an upgrade you have to ask for. Homeowners who switch typically notice it first in a quieter house, then in a smaller bill the following winter.
A soft credit check gives you a decision before you’ve finished your coffee, and most homeowners get approved without touching a dime of savings or booking a bank appointment.
From older homes near West Hill to newer builds farther east, here's a sample of recent work across Scarborough.
"Got three quotes for our split-level and these guys measured the most carefully by far. The install crew was done in a single day and left the place cleaner than they found it."
"Our sliding patio door used to jump the track every winter. The new one glides open with one finger and the difference in the draft is night and day."
"Called about a front door that had swollen shut in the summer humidity. They came out within two days and fixed the frame instead of pushing a full replacement."
"One pane went cloudy after a hailstorm and they just replaced the glass, not the whole window. Took less time and cost a lot less than we braced for."
"Our side door had been dragging on the floor for years. New hinges and a planed-down frame later, it closes like it's brand new."
"Two bedroom windows wouldn't stay open without a stick propping them up. Fixed in one visit and they showed us exactly what had worn out."

Sometimes a wall reveals rot or water damage only after the old window is removed, especially in older Scarborough homes. When that happens, we stop and show you exactly what we found before doing anything further. Minor rot around the opening is typically repaired as part of the install at a fair added cost, which we confirm with you first. We never just cover up a problem to keep the schedule moving, and you won't see a surprise charge for it after the fact.
Yes, if another licensed, insured company gives you a written quote for the same product and scope of work, bring it to us and we'll do our best to match it. We ask to see the competing quote in writing so we're comparing the same materials, warranty, and installation standard, not a lower-grade product at a lower price. It's a straightforward comparison, not a negotiation, and we're upfront if a quote simply isn't comparable to what we'd install.
Usually, yes. Once your products are manufactured, typically three to five weeks after your order, we book the installation date directly with you rather than assigning one automatically. If you need the work finished before a holiday, a move-in date, or a family gathering, tell us early in the process so we can plan the manufacturing and crew schedule around it. We can't guarantee a date that falls before materials are ready, but we'll work to get as close as possible.
Very little. Wiping down the frames and glass a few times a year keeps vinyl and fiberglass looking new, and an occasional check of weatherstripping and hardware catches small issues before they become bigger ones. Moving parts like hinges, rollers, and locks benefit from a drop of lubricant once or twice a year. We walk you through basic care specific to your products on install day, so you're not guessing at what applies to your particular windows or doors.
Yes, this comes up often in Scarborough's older housing stock, where original openings don't always match today's standard sizes. Every window we install is custom-built to the exact measurements of your opening rather than pulled off a shelf, so an unusual size or an out-of-square frame isn't a barrier. During your in-home visit, we measure carefully and flag anything unusual so it's accounted for in your quote, not discovered as a surprise on install day.
Yes, the workmanship warranty is transferable to whoever buys your home next, which is worth mentioning to your realtor if you're selling. There's no extra paperwork or fee to transfer it. Buyers and their inspectors often ask directly about window and door warranties during a sale, so having documentation on hand showing the work is still covered can be a genuine selling point rather than just a nice-to-have.
One of our owners will visit your Scarborough home, measure every opening, and email you a fixed-price quote before the visit is over.
