Why Proplas

What to expect from your window or door project

Good results depend on more than the product. Measurements, installation details and finishing work need the same attention as style and glass.

A clear quote

The product, installation method and finishing work should be understood before the project moves ahead.

Products suited to the opening

Operation, glass, finish and hardware are considered in the context of the room or entrance.

Accurate measurements

The existing opening is measured and reviewed before final product details are ordered.

Installation and follow-up

After installation, operation and basic care are reviewed and you know who to call with questions.

Homeowner feedback

What customers have said about their Proplas windows

Three homeowners describe their experience with Proplas window projects.

“We replaced all 12 of our windows with Proplas over a span of several years. We finally replaced the last two. We wouldn’t have chosen to have any windows replaced in the winter, but he got each window in and out so fast the house didn’t go down even a degree while the heat was off.”

Ann & George HallVaughan, ON

“I have to tell you that the best purchase I have ever made has been the Proplas windows that have been recently installed at my home.”

Jack DurhamToronto, ON

“I love my windows. I had five companies out and nobody could do the job except Proplas. I’m very happy with everything you have done and the service.”
