3 Meilleures Fabricants de Fenêtres et portes à St. Catharines, ON

If there were ten stars I would have given a ten star review! I can not say enough great things about this company. Punctuality, workmanship, professionalism, and customer service were all above and beyond my expectations. I had french doors put in to replace my old sliding doors and they are beautiful. I wanted something fixed and there were no issues with Clark who was one of the men who installed our doors to come out right away when asked. Everything was cleaned up nicely and installed perfectly! Clodette was really nice to talk to and the price was decent. I look forward to working with them again in the future to have windows installed. Thank you Clodette to you and your team for such exceptional service!

We were very impressed with the work that was done installing 5 windows and 3 doors in our home, so impressed that we have gone ahead to have another door and window installed. Clodette is very knowledgeable and the people who install the windows know exactly what they are doing. You can trust this company to tell you what to expect and their price is reasonable. Highly recommended.

Great Northers was absolutely amazing from start to finish!!! We just had a new back door and some extensive work done on the install because it was a tricky project. 10/10 work and great people to work with!!

Amazing company! Clodette is an amazing owner and she is professional and caring. Had to wait for the windows but that was ok. It was cold yesterday and they were very quick in removing the older windows and installing new so the house wouldn't freeze. At least there were no wasps, right? The installers were professional, friendly and very detailed with their work. Highly recommend this company. Very impressed! Price point was good too - Susan M Répondre

Highly recommend Permanent Siding and Windows for your next home project! Darryl (owner) and his team work hard and take pride in what they do. Attention to detail and achieving the high standard they personally set, are what set them apart from their competitors. You know your job will get done thoroughly and the right way - no short cuts. Competitive pricing and amazing value for what you pay.. Permanent Siding and Windows all the way.

We had our homes’ siding, soffit, facia, eaves, and downspouts replaced by Permanent Windows and Siding and could not be happier. Amazing quality workmanship and products. Very professional attitude by the teams doing the work. I recommend this company highly. We are in Fort Erie.

The work was very good quality. We were very happy with the team and their professionalism. The work was done in a timely manner, and great value. I would highly recommend Permanent Siding and Windows.

We would certainly recommend this firm. We found their product and workmanship to be excellent and we were very pleased with every aspect of their work - Trevor C Répondre

Just had windows done today (despite the less than ideal weather for him) by Mark and his crew. I was sold on using Mark's Windows and doors after the first five minutes I spent with him the day he came to give me a quote. Very professional, no-pressure, and extremely knowledgeable. I was 100% confident that he was going to deliver a good product and top notch workmanship. They were quick, cleaned up after themselves, and the windows were as promised and look great. Price was also very fair. Highly recommended!

Called Mark to see if he could put a window in my kitchen that was being renovated. There was no existing window all he needed to know was it on siding or brick. He suggested what type of window to use and the size. He installed the window and it was amazing. We were so impressed with his work we just got him to install a front door unit with the panels and also a storm door. Did an awesome job again. Will be calling him when it is time for us to do our windows. Great job and great work and he is very personal.

Mark and Will did a great job at our house. They replaced all windows and doors that were in much needed repair and their price was fantastic! We shopped around given the full replacement needed (6 quotes) and Mark’s price was easily the best.
