Great company to work with. Professional in all dealings from start to finish, the staff at CK were very helpful and accommodating (5 stars) and the price was very reasonable. I even received a senior discount that I did not expect. My wife and I are extremely pleased with the final results.
I recommend them full heartedly.

I replaced 3 bedroom windows in May 2017. In late 2019 I noticed moisture between the glass which would freeze into ice crystals in several of the panes. My warranty was a lifetime guarantee on the windows. When I called in early 2020 to report this problem I eventually was told there was no warranty on the windows as the supplier was out of business and it was not Comfort King who was responsible for the windows.
In 2020, 2 employees came to look at the windows and did some caulking. This did not prevent the moisture to appear during that and subsequent winters.
Discussions with the manager failed to provide any support or assistance with this problem. It was basically my problem not theirs.
I understand there has been a change of ownership and the current ownership is not taking responsibility for windows supplied by the previous supplier. I had thought I was buying good quality windows from a long standing local company. This has not been the case

However the manager I spoke with continued to take no responsibility for the windows which were defective within 2 years of installation.
Repeated attempts failed to provide any help with the issue
It is my understanding that Comfort King had changed ownership and appears to not be taking responsibility for windows sold prior to the change of ownership.
I had put my confidence in a long standing local company only to be very disappointed in the manner in which I was dealt with. Basically I was told it was now my problem not Comfort Kings.

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..
