Every window we supply is custom-sized to your existing opening, with a full range of glass packages available — from double-pane to energy-efficient triple-pane — along with a wide selection of frame colors and hardware finishes to match your home.
Our entry doors come in steel or fiberglass slabs with insulated cores, plus over 20 decorative glass inserts to choose from. Smart-lock-compatible hardware is available for Yale, Schlage, and August systems.
We supply two-, three-, and four-panel sliding systems with commercial-grade rollers and built-in retractable screens, plus an option for privacy blinds fitted between the glass panes.

From a front door that won’t latch to a closet door that’s come off its track, our technicians handle installation and repair without passing you off to a second contractor.
Four steps, each with a clear timeframe, so you always know what happens next.

Storefronts, offices, and multi-unit buildings across Whitby rely on us for commercial-grade door installation and repair that keeps downtime to a minimum.
"Our patio slider was stuck for months. They replaced the rollers and track in under two hours and it's been smooth since."
"We had three closet doors replaced upstairs. Clean install and they didn't leave a mess behind."
"One window pane had fogged up. They just replaced the glass instead of pushing a full window swap on us."
"Our storefront door was dragging on the frame. They fixed it the same day without closing the shop."
"Front door wouldn't lock properly in the cold. Turned out to be a quick hardware fix, not the whole door."
"New windows installed in a day and a half for the whole main floor. Crew was tidy and on time both days."
Our crews are based right in Whitby and work throughout the surrounding Durham Region communities — every measurement, install, and repair comes straight to your door with our own licensed team.
Spots fill up fast once the season picks up. Reach out now and we'll lock in a time to measure, quote, and get your install on the calendar.
In many cases, yes. If your frame is still in good condition and only the glass unit has failed — fogged, cracked, or lost its seal — we can usually replace just the glass and leave the existing frame in place. During your estimate, we'll confirm whether your specific window qualifies or whether a full replacement makes more sense.
A technician visits your home, measures the windows or doors involved, discusses the materials and styles that fit your project, and gives you a fixed written price before any work is scheduled. There's no obligation to book after the visit, and no charge for the visit itself.
Both. Alongside new commercial door installations, we repair existing storefront and office doors — hinges, closers, frames, and hardware — and can usually schedule the work around your operating hours to avoid closing during business hours.
Spring and fall tend to book up fastest as homeowners prepare for temperature swings. We recommend reaching out two to three weeks ahead during those seasons; winter and summer generally have more flexible scheduling.
Every technician who measures, installs, or repairs your windows and doors is part of our own licensed and insured team — we don't subcontract the work out to third parties.
We're based in Whitby and regularly work throughout Brooklin, Port Whitby, and the surrounding neighborhoods, along with nearby Ajax, Oshawa, and Pickering. If you're just outside these areas, reach out and we'll confirm whether we can take on the job.
