Licensed, insured technicians handling every door, window, and lock job in Oshawa.
No advertising budget in the early years. Just jobs done properly and customers who mentioned it to someone else.
A two-person operation chasing draughts out of older homes, one street at a time.
Certification from the manufacturers we fitted most, which turned repair work into full installation work.
A larger trained team let us take on communities across the region without dropping the standard.
Still owner-run, still on the tools, and still measuring ourselves on repeat customers rather than volume.
You cannot talk a door into closing properly. Either the frame is square and the hardware is right, or it is not. Windows & Doors Oshawa works to that standard across Oshawa because it is the only part of this trade that customers can actually verify.

Our mission is simple: to make every property safer, stronger, and more efficient. We achieve this by combining prime-quality materials with expert services tailored to each client’s needs. Integrity, transparency, and customer satisfaction guide every step of our work. Clear communication, upfront pricing, and long-term value are at the heart of our approach.



Windows and doors are more than design features — they’re structural elements that protect what matters most. That’s why we stand for:

From routine repairs to full replacements, Windows & Doors Oshawa handles every part of the job in-house, so you are not stuck juggling multiple contractors.

No matter the size of the project, you get the same trained crew, clear communication, and attention to detail from the first call to the final walkthrough.
Parts and labour both, documented and dated, so a claim never turns into a discussion.
A clear figure and a clear explanation, then space to think without anyone chasing you.
The same care with your property that we would want shown to ours, on every single visit.
