We recently had our sliding patio doors replaced with garden doors with interior blinds. We have received so many compliments on our doors. Mike and his crew (Mike and Anthony) are very friendly and professional. It was a pleasure having them in our home. The installation was seamless and clean. They already have someone who will be ordering from them, after seeing these doors at our place. I'm sure there will be more to come. Thanks guys!

I have nothing but good things to say about the services I have received from Clera. About 4 years ago I purchased a new front door from Clera. The salesperson was knowledgeable and understood what I was looking for. When it came time for installation, the installers were professional and friendly. They discovered a small dent in the door at the bottom and told me that they had ordered a new door . This was done before my final inspection. Based on this experience, I had new windows replaced in a rental home in Kingston. This salesperson was also very knowledgeable and took the time to help us. He even inspected other windows and told us which ones did not need to be replaced. More recently, I have purchased two new windows for my own home in Ottawa and have been equally pleased with the service, quality of workmanship and the windows themselves. I always recommend Clera to anyone that I know who are looking for windows or doors.

Excellent! We have loved our dealings with Clera. Rod was amazing in listening and understanding the look we were trying to achieve and then suggesting products with the appropriate features. The windows were delivered within the expected delivery time frame. The installation was done quickly and the crew was very professional and accommodating. The windows we had install have made the house much brighter. The doors we had install feel very solid, despite both presently unique challenges. Clera's quote wasn't the cheapest quote we had but their price was certainly competitive and the results have been well worth the money.
