About Us

At Double G Windows & Doors we bring authentic European craftsmanship to Canadian homes. Founded by Juraj, a craftsman who understands the difference between windows that truly perform and those that merely get by, we specialize in importing premium aluminum windows and doors directly from Slovakia to serve the Greater Toronto Area.

How was GG Windows & Doors born?

Back home in Slovakia, he worked for Slovaktual, a manufacturer of premium aluminum windows and doors. He knew the craft. He knew how a perfect corner was supposed to look. He knew the difference between something that holds up… and something that just holds on.

Then came life in Canada and with it a career in construction. Day after day Juraj saw what passed for “standard” in Canadian builds: poorly welded corners, loose seals, cheap materials that couldn’t handle a proper winter.

He couldn’t ignore it. Not someone who knew what real workmanship looked like.

That’s why he founded GG Windows & Doors to bring true European quality to Canadian homes. Clean lines. Durable materials. Sleek design that fits both modern and traditional architecture. Windows and doors that actually do their job and look good doing it.

Today, we work closely with architects, builders, and homeowners who don’t want compromises just great design and lasting performance.

We import high-performance aluminum windows and doors straight from Slovakia crafted with precision, built to last.

European quality. Canadian homes. No shortcuts.

We proudly serve the Greater Toronto Area, including Toronto, MississaugaEtobicoke, Brampton, Vaughan, Markham, Richmond Hill, Oakville, Burlington, Milton, Pickering, Ajax, Whitby, Oshawa, Aurora, Newmarket, King City, and Caledon. We also love taking trips up to Muskoka.

Right here in Nitrianske Pravno, Slovakia, our small team is doing something we’re pretty proud of – making windows the old-school way, but with modern twist.

We use German-engineered profiles because, let’s be honest, the Germans know their stuff when it comes to engineering. These frames are tough, keep your home warm, and look fantastic. It’s proper European quality, made right here in Central Europe.

Our process? Nothing fancy – just skilled hands, attention to detail, and checking everything twice. We’re a small company, so every single window matters to us. No shortcuts, no rushing – just good, honest craftsmanship.

Whether you’re building new or replacing those old drafty windows, we’ve got you covered. Our Slovak-made windows with German profiles will keep your home cozy, secure, and looking great for years to come.

review
We got our windows and doors replaced, and I’m very impressed - the quality is exceptional. They did a great job and offered us several options. Replacing windows and doors in an old house isn’t always easy, but George and Peter were very polite and professional. I would recommend this company anytime.
