Vinyl Windows & Doors

Over the years, our experience has taught us that there is, in fact, something better than wood when it comes to windows and doors, and that is vinyl.

Vinyl comes in a range of thicknesses so we can create the exact size of window you require. Vinyl is remarkably robust and durable and here at Clera, we only use 100% virgin uPVC vinyl which retails at an amazing price. It ticks all the boxes for versatility, good looks and performance.

Forget white or grey, the spectrum of colours that vinyl is sold in is quite mind-blowing. Its ability to insulate is legendary so vinyl replacement windows and doors in Sarnia offer incredible energy savings for your home both in terms of heat retention and lower household bills. Vinyl is lightweight so super easy to manage for the householder and to fit. The finish retains a brilliance that endures for years with the minimum of maintenance so your home will keep that just refurbished look long after we have been out to install your new joinery.
