We are rightly proud of our heritage, providing bespoke, quality replacement doors and windows to the homes and businesses of Windsor since 1978. Take a look at Clera’s quality, our shop window can be seen all across Windsor.

Selected as the top pick in our product category by HomeStars, Clera is a top manufacturer in Canada and we are proud of our commitment to excellence. With our large selection of windows and doors, Clera is sure to have whatever it takes to suit your demands. Clera has been in the window and door manufacturing industry for many years and we know how to make discerning homeowners happy. We have long served the city of Windsor and the surrounding areas and are excited to work with you. The weather can get pretty bad in the automotive capital of Canada. Be prepared by installing only the best doors and windows in your home.

Clera does not sub-contract any of its manufacturing processes. We make everything from scratch in our Ontario factory which is why our prices are so competitive and how we are able to produce such consistently good quality products. This allows the customer to choose exactly what they want for their home or business without having to shoehorn their desires into the rigidity of bulk manufactured joinery. We are so confident in what we make that all our units come with a comprehensive whole life warranty and that includes all parts, not just some, and all repairs. You just won’t find better from any other retailer of windows and doors in Windsor.

Vinyl Windows & Doors

Vinyl is Clera’s material of choice because there are so many advantages to the consumer and our experience in the field has proven vinyl to be the winner hands down time after time. Vinyl won’t limit your style choices; all of Clera’s comprehensive selection of replacement windows and doors in Windsor are produced in vinyl rather than wood. Available in a range of thickness from 0.5mm to 20mm, our 100% uPVC grilles offer you all the flexibility and versatility you want and at an amazing price.

Vinyl is amazingly robust and tough, ideal for the harsh Canadian winters. Yet it is also incredibly lightweight so units are easy to open and close without feeling insubstantial and flimsy. Vinyl keeps its good looks year in year out with the minimum of input from you, the householder. It rates highly for its R-value so you can feel reassured that whilst your home is snug and warm, you are also helping the environment.

Clera can guarantee a quality product and fit because we keep total control over the entire process. Clera has its own team of installers who are trained to our own rigorous standards and also work to the guidelines set out by the Canadian Standards Association.

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.
