Step 1: Choose Your Replacement Windows 

We are bound to have new windows to suit your Greater Toronto Area property. Browse through our showroom collection and choose between bay and bow windows, casement windows, high profile or fixed windows, awning windows, and more. Quality replacement windows from Clera will not only look good, but will also increase the value of your home. Our factory uses the latest technology and materials to maximize fit and ensure they are energy-efficient as part of our commitment to the environment and to saving you money.

It may surprise you to know that our company favours vinyl windows over wood. After many years in this business, vinyl continues to be our top choice of material because it is exceptionally durable, hard-wearing, and rarely needs repair. Our vinyl windows are available in a range of thicknesses from 5mm to 20mm, so there is plenty of flexibility for our installation team to accommodate your needs. Your replacement windows will be lightweight, ensuring they open and close with ease, and are easy to handle during your Toronto window replacement process.

Step 2: Design Your Replacement Doors 

When you use our Virtual Door Designer, in three simple steps you will be able to design your new exterior doors with your own choice of glass, grille and colour. Within a few minutes of using our design tool, you’ll notice that we have something for every house and its specific requirements – all made in either stainless steel or fibreglass. From sliding and patio doors to storm doors, no window and door company in Toronto can match Clera’s range of styles or exceed our level of quality at such an unbeatable price.

If we don’t have the exact shade you are looking for, our team can personalize a custom colour scheme just for you. Our unique colour retention technology will ensure your new Clera replacement windows and doors stay as shiny and sparkling as the day they were installed. If you are focusing on insulation, both for your comfort and energy-related purposes, then you can rest assured that your new windows and doors have some of the highest energy-efficient R-values and are ENERGY STAR® certified, so the heat stays within your home.

Additionally, our replacement windows and doors offer an unparalleled level of security and will reduce external noise, guaranteeing your house is a warm and safe environment.

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.
