Windows & Doors in Oshawa.

Replacement windows and doors for Oshawa — century homes, postwar bungalows and fast-growing north-end subdivisions.

Durham Region

22+ years · 1,500+ projects · 40-year glass warranty · Free in-home consultation

Local service, factory-direct quality.

Oshawa’s housing stock tells the city’s story: solid early-1900s homes in McLaughlin and around the downtown, postwar bungalows built for auto-industry families, and a fast-growing north end — Windfields, Kedron, Samac — filling with new construction near the university. Older homes here often still carry single-pane or early double-pane units that leak heat all winter, while lakefront streets in Lakeview face raw wind off Lake Ontario. We build every replacement to measure at our Etobicoke facility and install with our own crews, a direct run east on the 401.

A straight run east on the 401 — regular installs across Durham.

Oshawa questions

Good to know.

What homeowners in Oshawa ask before getting started. Something else on your mind? Just ask.

Which parts of Oshawa do you cover?
All of them — including Windfields, Kedron, Samac, McLaughlin and the surrounding Durham Region. If you're just outside Oshawa, we almost certainly still reach you; just ask when you request your quote.
How does the free consultation work in Oshawa?
We visit your home, measure every opening and talk through materials, finishes and budget — free, with no obligation. Your itemised quote follows within two business days. Our crews install across Durham Region regularly, so Oshawa visits fold into routes we already run — scheduling is straightforward year-round.
How long will my project take?
Every window and door is manufactured to measure at our own Toronto facility, so lead times stay in our hands rather than an importer's. We confirm the manufacturing timeline in your quote, and installation is booked as soon as your units are built and inspected.
Can you install windows in Oshawa during winter?
Yes — we install year-round across Ontario. Our crews work one opening at a time, so your home is never left open to the cold, and we use foams and sealants rated for cold-weather installation.
