Windows & Doors Oshawa has spent close to three decades working on homes across this city, from the character houses near downtown and Vanier to the newer subdivisions out by Windfields. That range of experience means our licensed crews know which window styles hold up best on an older frame, which door hardware makes sense for a new build, and how to price a job honestly, with no surprise add-ons once work begins. Every project, whether it’s a single cracked pane or a full-home window and door upgrade, is handled in-house from measurement through cleanup, backed by a workmanship warranty.
From a single foggy pane to a full basement window install, every job on this list is measured, quoted, and completed by our own licensed technicians, start to finish, with no subcontractors brought in along the way.

Read moreFix the glass, keep the frame. Cracked, cloudy, or failed-seal glass is replaced in the existing frame, restoring a clear view and better insulation without the cost of a full window swap.
Read moreSticking, drafty, or hard to close? Worn balances, damaged screens, and misaligned sashes are diagnosed and repaired so the window opens, closes, and locks the way it should.
Read moreMore light, and a safer exit. Egress-ready basement windows are cut in and installed to code, brightening finished basements while adding a proper emergency exit point.
Read moreEntry doors set true and square. New front, side, and interior doors are installed plumb and level, with hardware adjusted so the latch lines up without forcing the door.
Read moreSwap an old door for one that performs. Warped, drafty, or outdated doors are replaced with better-sealing units sized and trimmed to fit your existing opening.
Read moreFix the frame, not just the symptom. Sagging hinges, sticking latches, and warped frames are repaired at the source, so the door keeps working instead of needing another fix soon after.

Emergency service
"Every window in our bungalow was replaced in two days. The crew laid down drop cloths, cleaned up each night, and the house is noticeably quieter now that the old aluminum frames are gone."
"We finished our basement and needed a proper egress window cut in. They handled the concrete work and the window itself in one visit, and it passed inspection with no issues."
"Our old front door swelled shut every summer. The new one they installed closes smoothly no matter the weather, and they took the time to match the trim to the rest of the house."
"The screen door off our kitchen had been off its track for a year. They replaced the whole thing in under an hour and it glides better than the original ever did."
"One of our big picture windows fogged up between the panes. Instead of pushing a full replacement, they swapped just the glass unit and it looks brand new again."
"We converted a linen closet into a pantry and needed a new bifold door to fit the opening. It was measured perfectly and hangs straight, which our old builder-grade doors never did."

For situations that affect your home's security, like a shattered window or a door that won't close properly, we prioritize same-day or next-day service whenever possible. Call or text our office and describe what happened. We'll ask a few quick questions to figure out whether it needs a temporary board-up or a same-visit fix, then get a technician out as soon as our schedule allows. Weather and parts availability can affect timing, but urgent security issues always jump the queue.
Condensation trapped between the panes usually means a failed seal, which repair can't fix. Other signs include a window that won't stay open on its own, visible rot or warping in the frame, drafts you can feel even when it's fully closed, and a noticeable jump in your heating or cooling bills. A single symptom might just need a repair, but two or three together usually point to replacement being the better long-term value.

Most straight-across window and door replacements that keep the same size opening don't require a permit in Oshawa. Projects that change the size of an opening, such as enlarging a window or cutting in a new basement egress window, typically do. We'll tell you upfront whether your specific project needs one, and we can handle the paperwork with the city so you don't have to.
Yes. If you're replacing several windows at once or taking on a full door package, ask us about financing options when you get your quote. We'll walk you through what's available based on the size of your project so you can spread the cost out instead of paying it all upfront. Terms vary, so we'll go over the specifics with you directly rather than quoting a rate here.
Our licensed team drives to you, whether that's a single window repair on one side of the city or a full-house door upgrade on the other, measuring, quoting, and installing everything on-site from start to finish.
Share a few details about your project and we'll follow up with next steps, usually within one business day.
