I decided that we would renovate my townhouse, among the first things that I agreed upon was to replace the old doors and windows. We thought it would cost us a lot because the project was quite extensive. However, upon consulting with Julian, we found out that it would be budget-friendly. We agreed to the deal, and the service crew did an impressive job overall. The results were much better than expected and we just love our new windows and entrance door.

If we would require assistance with our windows or doors again, we will surely give them a call!

We offer not only great products with exceptional customer service as well. We really want to ensure you get the best windows and doors for your home! At Comfort Windows & Doors Inc, you can get a no-obligation quote on replacing your windows or doors. Comfort Windows & Doors Inc does not employ commission-based salespeople.

What kind of window and door materials does Comfort Windows & Doors Inc offer?

You can find windows and doors of almost any material – wood, vinyl, fiberglass, and aluminum.

What do I need to know about vinyl windows?

Vinyl windows are one of the most popular in the industry because they are the ideal combination of performance with price. Vinyl windows are virtually maintenance-free and can have excellent energy efficiency. Vinyl windows are not affected by the harsh Canadian climate.

What kind of window styles does Comfort Windows & Doors Inc offer?

We offer many different styles of windows, including casement, awning, fixed casement, picture (fixed), double-hung, bay, bow, and transom windows!

What are the most energy-efficient types of windows?

The most energy-efficient types of windows available are casement, awning, fixed casement and picture windows. All our windows are Energy Star certified.

What should I know when buying vinyl windows?

There are a ton of window materials available today. Vinyl windows pose many benefits—they’re cost-effective, durable, weather-resistant and more! Comfort Windows & Doors Inc carries vinyl windows from a variety of manufacturers—you’ll have plenty of options to choose from.

Will my home comfort improve after installing energy-efficient windows (and doors)?

The obvious answer is ‘yes’ just because you’ll no longer feel the drafts that result from cold air entering through low-quality windows. There’s actually much more to an improved comfort level though. First off the insulation around your windows and doors is replaced with insulating foam which fills every void that might have been present resulting in more drafts. Window upgrades also keep your home more comfortable in the summer by
retaining cooled air and help to control indoor humidity throughout the year.

How do I know the new windows and doors I purchase are energy efficient?

All Energy Star products have a symbol and label on them that indicates they have been certified to meet stringent technical requirements. Always look for the Energy Star label when browsing for replacement windows.

What does it mean when a product is Energy Star certified?

Energy Star is a program run by Natural Resources Canada that was created to monitor and regulate the efficiency of various home construction products such as windows, appliances, furnaces, etc. Manufacturers submit their products to be tested and certified. If compliant, it means that products rank in the top 15 or top 30 percent in the niche in terms of energy performance. Energy Star certified products not only save money on your utility bill but also increase the value of your home.

When do I know that I need to replace my windows?

You can actively identify if your windows need to be replaced by being aware of the following:

  • You notice fog, condensation, or moisture on your glass consistently. When the view through your window becomes hazy like this it usually indicates that a seal has failed.
  • Certain areas of your home become faded from where the sun enters the window. This could be furniture, carpeting, or even hardwood and it means you need to upgrade windows because your current models are allowing harmful UV rays to enter your home.
  • Your current windows are not rated for the new climate regulations. Colder climates require a higher ER rating to satisfy energy efficiency recommendations. Your windows are grandfathered in and a replacement isn’t mandatory, but just know the amount of energy you are losing by having these lower quality units installed.
  • If your windows are having difficulty opening, closing, and locking it could be time for replacement windows or at the very least a repair. Having a window that doesn’t properly open is a violation of building codes and is a huge safety risk in case of a fire.
  • Rotting or pealing wood means the windows are past their prime and ready for replacement. The older your windows are, obviously, the more likely this occurrence will be.

What type of doors does Comfort Windows & Doors Inc carry?

We carry steel, fibreglass, wood, garden, french and patio doors.

Why is steel considered one of the best entry door materials?

Steel doors are known for their strength and durability and they are also your best choice if security is a priority for your home. Steel doors have become the most popular entry door in Canada because more people prefer not to have to deal with the need for regular staining, painting, and other maintenance. Steel doors protect against the elements while maintaining bright, contrasting aesthetics that improve your home’s curb appeal.

What locks do we recommend?

At Comfort Windows & Doors Inc we offer and recommend a German precision-made multipoint lock. The multipoint locks at 3 points on your door making it very difficult for unwanted intruders to break into your home.

How Can I Save Money When Buying Doors and Windows?

The government of Canada has allocated grants for helping to save energy by installing doors and windows that are energy savers.

We can help you getting the grant. For more information visit the Greener Homes Grant page on our website.
