Windows play an important role. They allow in natural light, increase ventilation and help beautify the space they occupy. Here are some additional benefits of replacing your windows:

    They’re more secure. New windows are built to be strong and are therefore less susceptible to burglary and break-ins. Many have advanced locking mechanisms as well. Plus, if your window happens to break, the glass is tempered and therefore designed to shatter into small, dull-edged pieces rather than large, dangerous shards.

    They’re more energy-efficient. Replacing your windows can help you reduce your energy bills. When properly sealed and installed, modern windows offer superior insulation. This helps keep your property cool in the summer and warm in the winter.

    They’re aesthetically pleasing. Choosing the right replacement windows can improve the curb appeal and value of your property.

    They block out UV rays. Most modern windows come with UV protection, which helps prevent your furniture, flooring, countertops and artwork from becoming discoloured. In addition, replacing your windows with ones that are UV-resistant can help prevent premature skin-ageing.

If your windows are drafty, have rotten frames or are difficult to open and close, it may be time to replace them. The team at Canadian Comfort Windows & Doors would be happy to help.

Choosing your windows and doors


The process begins with a customer representative from a window and door company visiting your home to do measurements and give you an estimate. There’s a large variety of windows and patio doors to choose from, and the representative can help guide you through the different styles and materials that are best for you.

Preparing your home


When the date of your replacement draws near, take the time to prepare your home. Move furniture away from window and door openings and ensure the replacement crew has a clear path through your home. Replacing windows and doors can shake and rattle your walls, so remove delicate items from shelves and valuable artwork from walls. Windows replacement often requires outdoor ladder work, so move anything outside that might interfere with ladder placement.

Replacing your windows


When the window and door replacement crew arrives, workers will proceed quickly and efficiently. Professionals bring drop cloths and other protection measures to cover flooring and furniture. The time it takes to replace windows and doors differs from house to house, depending on the job’s complexity. In general, a professional two-person crew can replace a window in about an hour. Large windows take a bit longer. Installing a patio door takes more time because the crew often needs to remove and replace rotten wood and make custom-built flashing. It can take half a day or more to replace a patio door.

Inspecting the work


Once a crew has installed a window or door, check it for scratches and dings. Open and close them a couple of times to ensure everything works smoothly. Don’t let the crew leave until you’re 100 percent satisfied.


Getting your windows and patio doors replaced is easier than you think. Many people are hesitant to replace their windows because they assume the process is complicated, messy and time-consuming. It may have been this way in the past, but today’s professionals can install your windows and doors quickly and cleanly. Here’s what to expect when you get your windows and patio doors replaced.

Choose the best time to replace your windows and doors


Rain, snow or cold weather can delay your window installation. In Ottawa, summer is typically the best time of year to get your window and patio door replacement because there’s less chance of delays. However, book in advance because contractors are very busy during this peak season.
