The Best Windows & Doors in Niagara Peninsula

The Niagara Peninsula is one of the most famous places in Canada, largely because it hosts one of the natural wonders of the world – the Niagara Falls. It is also rated among the top regions in Ontario in terms of quality of life and progress rates. In recent years, heavy industries have cut back on their operations, giving more room to the pedestrians and reducing the amount of traffic in the area. This has added to the popularity of the space, where you can expect more fresh air and less city bustle.

Hospitality and tourism are the two main developing sectors of the economy in this region. It will therefore come as no surprise to learn that thousands of tourists visit the Niagara Peninsula every month, which has significantly increased its placing in the overall global tourism ranking list. It is also one of the most preferred places for individuals post-retirement. The roads are clean and wide, government policies are fair, and it has ready connectivity with the United States through both air and land. The cost of living here is also very reasonable, which makes it an ideal place to live and raise a family.

Video Transcript

My name is Todd Huson. I am the district manager for the Niagara region. I’ve been with Clera Windows + Doors for 21 years.

At Clera Windows + Doors, we manufacture our own windows and we install them with our own factory trained carpenters as opposed to a contractor who buys the window from a manufacturer and installs it. At that point, you basically get two separate independent warranties. But with Clera Windows + Doors, you have a warranty through the manufacturer on the product and the installation.

Number one, again, we are one-stop-shopping. We have a very high-quality product and we stand behind our warranty.

I’d like to take this opportunity to thank all my customers through the past 21 years for your support and to invite any new customers to feel free to call me for a free, non-commitment estimate.
