Siding Contractors in St. Catharines

“So happy with the end result. From start to finish, the crew at Permanent Siding and Windows was very thorough and professional. We had six windows replaced and a new bay window installed in about 4 days. The attention to detail was second to none. Special shout out to Emma for answering all my questions promptly. Great work guys!“

“Mark’s Windows and Doors are amazing!! We were the victim of a terrible tenant who had completely smashed the front door, patio door, and one bedroom window. We were paying for the repairs out of pocket and all other companies I had contacted had quoted very high prices and a timeline of 3-6 months. Mark’s Windows and Doors were honest, helpful, and had my best interest in mind through every step of the way! They quoted a very fair price and also had it done within the month, the longest part being waiting for the pieces to arrive. I highly recommend them for any door or window projects. They are honest people and I love to support honest, genuine, small businesses :) Thank you so much for everything, we appreciate all your help!“

“Just had my bedroom windows installed. They were a very reasonable price and look great. We are happy with our experience overall.“
