Video Transcript

My name is Les Stringer. I’m with the Barry branch of Clera. I’ve been with the company for about 21 years.

What I like most about working with Clera is they are a family-owned business and you feel like family working with them. You don’t feel like a big monster corporation. We’re treated like family and we try and treat our customers like family.

The big difference between us and most of our competitors is that we manufacture our own windows and doors, and we have for the last 41 years. Most companies either manufacture or install, whereas we do both.

Thanks to all my previous customers. There’s a lot of you out there. Anybody needing windows, please don’t hesitate to give us a call. We’ll look after you.

Why Choose Clera

Why take a chance with other window or door companies that purchase their products from another supplier, only to resell them to you for a higher cost?

Clera Windows + Doors is one of Canada’s largest, oldest, most dependable and reputable vinyl window manufacturers in Ontario. We fully manage and take care of your door and window replacement project from start to finish, ensuring every stage of your window or door project meets our lofty standards of craftsmanship.

Why are we Ontario’s most awarded window and door company?
