OUR STORY

Twenty years of window and door know-how, built here in Oshawa.

We’ve spent two decades installing and repairing windows and doors throughout the city, from character homes around Central Oshawa and Lakeview to newer subdivisions in Wind fields and Taunton. That range means our crew already knows how to work with older wood-frame openings and modern construction alike, and can recommend the material and fit that actually suits your home.

Every job, whether it’s a single patio door or a full-home window replacement, follows the same standard: an accurate measurement, a written price before we start, and installation by our own certified crew. We hold ourselves to that standard on every property we work on, and it’s how we’ve earned the trust of homeowners throughout Durham Region.

BUILT TO LAST

Materials that last, backed by a warranty that means it.

We install Energy Star certified windows and doors from established manufacturers, and every unit is custom-built to your opening rather than pulled from generic stock sizes. Vinyl, fiberglass, steel, or wood-clad: whichever material fits your home and budget, you’re getting a product built for the job, not a compromise.

Our workmanship is covered for as long as you own your home, on top of whatever warranty the manufacturer provides on the product itself. If a seal fails, a frame settles, or a door stops closing properly because of how it was installed, we come back and fix it at no cost to you.

★★★★★

"Our sliding patio door had been dragging for years and I finally called for a repair instead of replacing it. Took less than an hour and it glides like new now."

Karen T.,

Eastdale

★★★★★

"We had eight windows replaced before winter. The crew was in and out in a day and a half, and the draft in our living room is completely gone."

Mike D.,

Northglen

★★★★★

"Needed a same-week fix on a front door that wouldn't latch properly. They came out, adjusted the hinges and strike plate, and didn't try to upsell me on a full replacement."

Priya S.,

Windfields

★★★★★

"Got quotes from three companies and this crew was the only one who actually explained the difference between the window packages instead of just pushing the most expensive option."

Steve R.,

Lakeview

★★★★★

"Our 1970s bay window had fogged glass between the panes. They custom-built a replacement that fit perfectly and looks better than the original ever did."

Denise M.,

McLaughlin

★★★★★

"Replaced our patio door and a side entry door on the same visit. Both were sealed properly and there's noticeably less noise from the street now."

COMMON QUESTIONS

Your questions, answered honestly.

Don't see your question here? Call 289-278-3304 and we'll walk you through it.

How do I know if I need a window repair or a full replacement?

If the frame is solid and the glass or seal is intact, a repair like new weatherstripping, a hinge adjustment, or a reseal is usually enough to fix drafts or sticking. Full replacement makes more sense when the frame itself is warped, rotted, or the glass has failed between the panes. During your free estimate, we'll look at the actual condition of your window or door and tell you honestly which option solves the problem, rather than defaulting to whichever is more expensive.

What window and door brands and materials do you install?

We install a range of vinyl, fiberglass, and steel windows and doors from established manufacturers, chosen to suit your home's style and budget. All of our products meet Energy Star efficiency standards for our climate. We'll walk you through the specific options available for your project during your in-home estimate, including frame material, glass packages, and hardware finishes, so you can compare them side by side before deciding.

Do you handle permits for window and door replacement projects?

Most straightforward window and door replacements in Oshawa don't require a building permit, since you're replacing an existing opening rather than changing its size or the structure around it. If your project does involve enlarging an opening, adding a new one, or other structural changes, we'll flag that during your estimate and handle the permit application on your behalf so the paperwork doesn't fall on you.

Can new windows or doors actually lower my energy bills?

Yes. Older windows and doors, especially ones with worn seals or single-pane glass, let conditioned air escape year-round, which makes your furnace and air conditioner work harder. Replacing them with properly sealed, Energy Star rated units reduces that air loss and can noticeably improve comfort and lower utility costs. Depending on the program year, you may also qualify for rebates on current upgrades, which we can help you look into.

How soon can you come out for an urgent door or window repair?

We prioritize calls involving a door that won't lock, a broken window, or anything else affecting your home's security. In most cases, we can get a technician out within a day or two of your call, and we'll always give you a realistic timeframe upfront rather than leaving you guessing. If it's a true emergency, mention that when you call, and we'll do what we can to move you up the schedule.

What areas around Oshawa do you service?

We're based in Oshawa and work throughout Durham Region, including Whitby, Courtice, Bowmanville, Clarington, Ajax, Pickering, Uxbridge, and Scugog. Wherever you're located in the area, the same crew handles your measurement, installation, and any follow-up. If you're unsure whether your address falls within our service area, just give us a call, and we'll let you know right away.

Do new windows and doors need any special maintenance?

Not much. Wiping down tracks and frames a couple of times a year and keeping weep holes clear of debris will keep sliding windows and doors operating smoothly. Vinyl and fiberglass frames don't need painting or sealing the way older wood frames did. We'll walk you through any product-specific care tips at your final walkthrough so you know exactly what, if anything, your new windows and doors need going forward.
