Clera Windows and Doors despite the COVID-19 pandemic, still got my door and window installed in a safe manner. Hans and the Installer Rick both did a great job, leaving my self (a new home owner) feeling safe, and excited to show off my new home. The new hardware implemented in the windows give it a great modern look on the inside and can be opened with ease. 10/10 will be purchasing more in the future!

Bought my windows over 5 years ago and have been very satisfied with the product. Installation was seamless, clean, and very respectful. Just started having an issue with a stuck window and was given the run around. They were very clear that the “Lifetime, no-hassle” warranty only covers parts but no labour. So, either I can guess what the issue is, with random photos of the window for them to send me a new part that I would have to install myself, or I can PAY to have a service call for them to figure out what part is malfunctioning and then PAY to have them fix the window.
Sure doesn’t seem “no-hassle” to me.
Very sour after what was such a good experience, originally.

Talk about warranty and service !
I had my windows and patio door installed by Clera well over 15 years ago.
Recently one of our patio doors rollers was in need of service replacement. We called Greg at the oakville location and after exchange few emails and photos was quick to review the warranty with us and arrange for Trevor the technician to come and inspect issue. Soon after Trevor - Covid preparedness -came and install a new replacement part at no cost .
Thanks Greg and Trevor for the awesome service.
So if you are looking for a true high quality new windows and doors and most important a solid warranty with great service ...call Clera.!!

We needed to replace five windows of various sizes. We dealt with Gary from Clera; he was professional and did a good job explaining our options. The windows were affordable and we are very satisfied with the quality.

The installers were efficient and professional and installed the windows and flashing in one day, which was much quicker than we expected.

We will definitely consider Clera for any future window replacements.

Installers arrived on time, were thoroughly professional and polite. the job was completed quickly and they cleaned up after the job was done pretty well. Used Clera to replace windows and front door in May 2019.

Door exactly as ordered.

It hasn't been tested yet against a winter, but it looks like it should do fine. I haven't heard noises from expanding from the heat of the sun.

We shall see how it tests against the pass of time.

Quick and did a good job . Broke a piece of j trim and warped trim piece inside but other then that I was very happy.

I chose Clera windows to purchase and install a new patio door with blinds. Ken from Clera windows in Belleville is great to work with and the installation was professionally done.

We needed a complete tear out and replacement of a large bow window. Other even larger bow only needed glass replaced, and they did so plus they replaced a broken window crank. Installers were very experienced and have been doing this for decades.

We are very satisfied with our new picture window with 2 side opening windows, plus the additional 2 slide windows installed on the front of our house. The outside trim work combined with the new windows gives our house a great curbside appeal. Clera installed these windows meeting all our expectations, and their price was very good as well.
