Providing Excellent Service Since 1991

"I wanted to tell you that I am very happy with the back door. It looks wonderful, what a difference. Troy and DJ did a great job. They are extremely nice men, are very professional and certainly good at what they do. They once again kept the working area very clean while demolishing the exisiting awful back door and while working to install my new door. I would recommend your company and have to anyone who needs windows, doors, etc. Great job, well done!"

"We want to express our appreciation for all that you did to ensure that our windows of 19 years were replaced. It's impressive that the 'lifetime guarantee' was upheld after so long and with little paper work remaining. Kudos to Northern Performance Windows!"

- Cathy & Eric

"I just had my new front window installed and all I can say is 'Wow!". From start to finish your guys were fantastic! Peter came out to give us a quote and was friendly, helpful and knowledgeable. He listened to what I wanted and gave me exactly what I asked for. I was very please that he didn't try to push me into something that I wasn't interested in and when he asked if any other windows needed replacing he understood when I said it wasn't in the budget right now. Your quote came in $1000 less that other 2 quotes we received, which was a huge factor in ordering, but Peter and his professionalism sealed the deal. We will definetely be using Northern Performance Windows again and will highly recomment your business. Thank you so much!

"We have the highest praise for the installation crew. They were polite, knew their job, worked well together, cleaned up and restored both during and after the process.
What a sharp contrast from the crews who installed our sliding doors and windows over the past few years."

"We would like you to know that your team did a superb job on our installation of windows and patio doors last week. They are all professional, hardworking, knowledgeable and courteous, and were a pleasure to have in our home. We would not hesitate to recommend your team to any of our friends."

"On January 31st, my husband and I had the pleasure of hosting Tyler while he helped to install some garden windows. It was clear right from the start that Tyler takes instructions well and seriously. He is very accurate in measuring to get the window in properly and looking good. Both my husband and I enjoyed his sense of humour and his attention to his work. He was very thorough in cleaning up his work area. Both my husband and I would highly recommend Tyler for any job related to installing windows."

"I just wanted to send our words of appreciation for the fabulous door and window installation to our house in Washago on June 19th. We are really happy with the job, and want to especially thank Terry and Tyler for their very hard work in putting in the door. They were replacing an old door in an old home which turned out to be a really difficult retrofit that they successfully accomplished over many hours. It looks great both inside and out! It was a pleasure dealing with Al, John, and of course you Dave. Thanks to all of you. We will highly recommend your product and services."

"Just a note to say thank-you for the timely manner in which our new windows were fabricated and installed. I admit that I was skeptical in having the original windows removed and replaced but after witnessing the professionalism of your install crew Mark, Tyler, Terry and Ron, my apprehensiveness was thwarted. A special thanks to Jeremy for his patience in helping us to choose the style of window to best suit our needs and wants. Overall, it was a good experience and I thank all of you who were involved."

- John & Pat

"John and I recently had some new windows installed by your company. We were duly impressed with the professionalism and teamwork of the installers."

- Cheryl & John

"They were installed perfectly, not an error anywhere. The installer had over 25 years experience and he used every ounce of it to expertly install and direct the others to save time, money and error. Every aspect of the install was explained to us before the job even began. We had 18 windows including one very huge one, installed correctly the first time within 2 days, and the property was clean and glass free at the end of the job, the gardens were all intact. We were very pleased."
