Why gem windows & doors

1961. Elvis was on top of the charts, John F. Kennedy becomes the youngest US President and Russia launches Sputnik into outer space. Back at home, John Christopoulos starts GEM Windows, to provide high-quality windows and doors to Toronto homeowners and builders. In an industry of fly-by-night businesses, GEM has a well-earned reputation as Toronto’s oldest and most trusted window and door company. We’ve even had the same phone number since 1961.

How have we stayed in business so long? Simple; we listen more than we talk, to understand your needs, budget and priorities and then provide you with customized solution, not a one-size-fits all approach.

We work with you to accomplish your goals:

  • Making your home more comfortable
  • Reducing your energy bills
  • Letting in more light
  • Keeping your home more secure
  • Addressing specific problems like floor fading
  • Reducing or eliminating maintenance
  • Giving your home better curb appeal

The GEM Difference…

Quality products.

At GEM, we do our homework, and only work with manufacturers that offer great reliability, outstanding customer service and the very best product quality. We ask our manufacturers tough questions. Do they offer the options customers want? How good is their warranty? Are their products Window-Wise or Energy Star certified? Are they manufactured here, near our customers? We know every window manufacturer selling product in Canada, and only work with the best, a fact that our manufacturing partners understand and respect. A perfect example of this quality-centric approach is that in 2013, GEM became the first independent showroom and contractor in the GTA for Pella Windows, one of the oldest and best-known window and door manufacturers in North America.

Apples-to-apples price match guarantee.

GEM’s prices are very competitive. We might not always be the cheapest, but we are always the best value (price vs quality). In fact, we’re so confident that our pricing is competitive, we offer an apples-to-apples price match guarantee. If you receive a lower quotation on your job—provided the products and installation quality are equivalent—we’ll match the lower price and beat it by 10% of the difference.

Personalized service.

At GEM we don’t push products, we simply solve problems. We listen carefully to your needs and goals and create solutions to meet them. Our experience and well-trained salespeople look after our customers from their first visit to our 5,000 square foot state-of-the-art showroom through their installation and beyond.

The GTA’s Best Installations.

A high-quality window installation is just as important as the products being installed. All GEM Windows installers are experienced, well-trained and service-oriented professionals. We don’t overschedule and we will never a rush job just to move on to the next one. Quality windows are a significant investment and quality installation ensures that this investment is protected and maximized.

Innovative products.

GEM Windows was the first company in Canada to offer windows with a self-cleaning coating. We were the first to offer V-groove beveled glass, one of the first companies in Toronto to offer modern thermal windows. Our longstanding expertise in the window industry means we can distinguish between passing fads and material improvements.

Ecologically Minded.

We recycle all of the glass and aluminum from every old window we replace whenever possible. Observing LEED certification principals, we’ve updated our showroom lighting to reduce energy consumption and have plans implement additional energy-saving measures, including painting our roof white to reduce cooling bills by 20 per cent, installing solar panels and purchasing electric fleet vehicles.
