We had a fantastic experience with Comfort King. We hired them to replace all of the windows in our house, and they were one of the only companies that could do the specialized work needed to preserve some of our heritage inner windows while replacing the outer ones (without going the insert route, which we didn't want). They did an outstanding job. Our windows look beautiful and we get tons of compliments. The staff were pleasant and professional and very easy to work with. Installation went smoothly. We couldn't be happier. Would highly recommend

Professional. Clean. Punctual. Responsive. Attention to detail. Accommodating. Beautiful!
These are some words that can be associated with the service and product we received from Comfort King. We replaced 16 windows and 2 doors. From Athena in Sales, to the Installation team, to the Finance team each were a pleasure to work with and the final result; Remarkable.

The entire process from beginning to end was seamless, professional, on schedule, and on budget. Before making our purchase decision, we reached out to six different Ottawa window & door retailers to obtain pricing and availability. We worked with Athena on the initial purchase and found her to be very knowledgeable, professional and timely. The follow-up with the scheduling process was seamless and the delivery / installation was flawless as well. The new door is as expected - a superior design!

Thank you Comfort King - we'll be back!

Windows and patio door look great, function perfectly and were installed in November 2020 by professionals who did a fine job. Thanks to Athena who set it all up. Happy despite the COVID-19 delays .

I had a great experience with Comfort King buying the windows and doors for my new home. Athena was a great help in choosing the door and windows that would fit my project, and has been there to answer all my follow up questions in a timely manner. The order showed up on time and everything was as expected. Overall it was a great experience and I highly recommend them if you need high quality windows and doors in the Ottawa area.

From my first inquiry about a garden window, the response was fantastic. Athena was great in the planning process and designing this large project. The installation team was helpful, efficient, and friendly. This window has completely transformed our kitchen and I am thrilled.

Door was replaced with a great replacement as offered by Sales Representative, Athena, who understood my wishes and offered a great replacement at a reasonable cost.
Installation was completed, after the Covid delays by two friendly and efficient installers. Work was done with the new separation rules and the tidying up was also well done.
Completely satisfied with the final installation..

This was second experience with Comfort King !... Aldo, once more, was knowledgeable, courteous and efficient in guiding us through the order/purchase process... the products were delivered in the time span promised... then installers, Jesse, Dustin, Tim, Steve, Tom and Chris did a phenomenal job with replacing all of our windows... they worked in a timely and diligent manner... a very personable and tidy crew ! ... we highly recommend your products and company !

I recently had 11 windows and my front door replaced by Comfort King. My sales person, Jennifer, was outstanding in every respect. We discussed my specific need (i.e., getting rid of the transoms above each window, removing the grills in every window, triple glass in every window, only some windows requiring an opening capability and my requirements for a new front door). We met several times in person, exchanged several phone calls and e-mails, and she conducted an on-site visit to obtain the necessary information for the quote. I was very impressed with the detail of the quote and specifically the great price. I was contacted within three weeks to indicate the windows were in and installation was scheduled for the following day. The two day installation planned over two day was completed in six and a half hours, in part, because three crews arrived at the house. The team led by Chris were very professional and did a perfect job. They removed the existing California Shutters over each window, exchanged the old window for a new one and re-installed the shutters. They constantly kept me informed of their progress and expected completion time. They did a great job in minimizing the "mess" and did a fantastic job cleaning up after. The following week, the door arrived, with replaced scheduled for the following day. Chris and his associate Thomas completed the door installation within three hours. Again, I was extremely impressed with their professionalism and expert workmanship. I am very satisfied with every aspect of this project and would highly recommend Comfort King to anyone who might be considering window and/or door replacement.

We are thrilled with our garden window. It’s like having the outdoors in our now much sunnier kitchen. Our salesperson was knowledgeable and helpful in finding just the right window, and the craftsmen who installed it were precise and careful. Massive home improvement that added $$ of value to our home. Thank you, Comfort King team!
