Once known as Medina, Keswick was part of the township of North Gwillimbury before amalgamating with Georgina which it is now part of today. While formerly just cottage country before development in the late 80s, Keswick still offers great boating and camping or cottage life for residents and visitors alike. In the summer months they enjoy spending time on the beach or boating on the lake while winter allows for snowmobiling and ice fishing to pass the time.

With such lovely scenery, it’s no surprise new houses and cottages are popping up all around the area, while current residents are eager to upgrade their estates. That’s where Clera Windows and Doors can offer their services. Founded in 1978, we are still a family run business to this day so you can trust we will take the utmost care when servicing your home. Our fenestration installation technicians all surpass standards set by the Canadian Standards Association and many of them have over 20 years’ experience working for us.

Vinyl Windows & Doors

The introduction of vinyl windows and doors was in Canada in the 1960s, and it has seen an enormous rise in popularity among the people since its introduction. The superior energy efficiency of vinyl over wooden windows and doors made it a popular choice for home fittings. Vinyl is an artificial material constructed from the combination of ethylene and chlorine. Once these elements are processed, they combine to form Polyvinyl Chloride or vinyl for short. Unlike wood, vinyl synthetic nature makes it resistant to humidity, moisture, and decay. Apart from this, it has excellent energy efficiency, durability, and low maintenance cost.
