We’ve enjoyed working with Riel at Reliable glass and Windows Ltd. over the past few years. He has replaced numerous windows in our home. He is great to work with, friendly, professional and very knowledgeable. We are extremely happy with the quality of his work and would highly recommend him.

Jane Glass

We were extremely happy with the work we received from Riel and his team at Reliable glass and Windows Ltd. I would definitely recommend them to family and friends without hesitation. They were very conscientious about their work, took their time and I felt like they made sure everything was as good as they thought it should be.

They didn't rush through the work, the cleanup was great and the price was better than competitors. They replaced a large window for us and I will definitely use them in the future.

Riel at Reliable glass and Windows Ltd. has been wonderful to work with. This summer we got a huge bay window and a patio door window replaced. He was always quick to respond, had great prices and left our house spotless after working in our home. I wouldn’t hesitate to call him back if we need more windows replaced in the future!

Hans Van Der Laan

We’ve dealt with Riel Fournier and his company for almost 25 years. Back then, over a few years, he replaced a number of windows in our new home that had seal problems, caused during the window manufacturing process.

We have continued to use Riel ever since for all of our window replacement requirements. Reliable Glass and Windows Ltd. is a smaller operation, providing us with prompt, individualized service. We would highly recommend Riel and his company for your window requirements.
