Gem Windows & Doors

GEM Window & Doors has a well-earned reputation as Toronto’s oldest and most trusted window and door company. We’ve had the same phone number since 1961—a real rarity in an industry where “windows and doors” has become synonymous with “fly by night.”

At GEM, we listen more than we talk. We start where you are—your needs, your budget and your priorities—to provide you with customized solutions, not a one-size-fits all approach.

We’re partners in your decision-making process, advising you on the best options to accomplish your goals:

Increasing Home Comfort Reducing Energy Bills Maximizing Light Enhancing Security Solving Specific Problems Like Floor Fading Eliminating Maintenance Improving Curb Appeal
