Ottawa Windows & Doors – Frequently Asked Questions
How do I know when it’s time to replace my windows or doors?
Common signs include drafts, rising energy bills, condensation between glass panes, difficulty opening or closing, and visible wear. If your windows or doors are more than 15–20 years old, replacement can significantly improve comfort and efficiency.
Are new windows and doors energy-efficient in Ottawa’s climate?
Yes. Modern windows and doors are designed specifically for Ottawa’s extreme weather. Features like Low-E glass, argon gas fills, insulated frames, and tight sealing help reduce heat loss in winter and keep your home cooler in summer.
Do I need a permit to replace windows or doors in Ottawa?
In most cases, permits are not required for like-for-like replacements where the size and location stay the same. A permit may be needed if you change the size, location, or structure, or if your home is in a heritage area. It’s always best to confirm with the City of Ottawa.
How long does window or door installation take?
Most window or door replacements can be completed in one day, depending on the number of units and project complexity. Your installer will provide a clear timeline before work begins.
What types of windows and doors do you offer?
We offer a wide selection of window styles including casement, awning, bay, bow, picture, and sliding windows, as well as front entry doors, patio doors, and custom options to suit Ottawa homes.
Can replacing windows and doors lower my energy bills?
Yes. Energy-efficient windows and doors reduce drafts and heat loss, which can lower heating and cooling costs over time. Many homeowners notice improved comfort immediately after installation.
What makes professional installation important?
Even the best windows and doors won’t perform properly without correct installation. Professional installation ensures proper sealing, insulation, and long-term performance while meeting Ontario Building Code standards.
Can I see window and door options before buying?
Absolutely. We encourage Ottawa homeowners to visit our showroom to compare styles, glass options, finishes, and hardware in person before making a decision.
Do you serve areas outside of downtown Ottawa?
Yes. We proudly serve homeowners throughout Ottawa, including Kanata, Barrhaven, Nepean, and Orléans, as well as surrounding communities.

Real Reviews From Ottawa Homeowners
⭐⭐⭐⭐⭐
Quality Workmanship
I wrote a review on BBB in which I gave this company a five star rating. Canadian Comfort did a fantastic job. The difference from before and after is amazing. The outside noise is diminished considerably and the warmth retained in the home will save me a fortune in heating this winter. Your customer service is wonderful. You gave an accurate time line from start to finish of the work to be done. The team doing the work were friendly and awed me with their skill.
⭐⭐⭐⭐⭐
Very Very Pleased
Very very pleased with the Canadian Comfirt job replacing windows in my home. Tidy work, no mess at all when they were done, worked hard and consistently to get the job done on schedule, were polite and friendly but just got on with the work and I was able to continue working from home. The windows and framing are great, so happy to see out clearly after years of broken seals and fog, ha!
⭐⭐⭐⭐⭐
