I had the pleasure of working with Great Northern Home Exteriors Inc. to have a window replaced, and two new window cut outs into our home. Working with Clodette was an absolute pleasure, she was professional, provided competitive pricing, and is an honest hard worker. Clark the technician who installed all the windows is a true artist and a veteran in his trade. My expectations for the project were exceeded and then some. I really have nothing but excellent things to say about this company. Hands down I would contact Clodette again for any window/door projects. Thanks again Great Northern, look

I had the pleasure of working with Great Northern Home Exteriors this spring to have all of the windows replaced in my home plus a couple of large exterior doors (10 windows, 1 patio door and 1 sliding glass door) The crew were friendly, professional, tidy, careful and on time everyday. I am incredibly impressed with the craftsmanship of the installers. I greatly appreciated their attention to detail and also the fact that they protected my home with high end materials and thoroughly cleaned up at the end of each work day. Claudette did a wonderful job keeping the lines of communication open throughout

Fantastic job, we couldn't be happier. The installer arrived on time was professional and friendly with our children. Our window looks amazing. All debris was taken away and cleaned up. Couldn't be happier with the install process. Clodette was helpful along the way. Answered our questions promptly. Highly recommend clodette and her team !

Very professional company. Pricing was very competitive and the installer was one that takes his time and does the job right. When they removed the old bay window they found a pile of rot. It was shown to me and repairs made without an extra. Yes that is correct, no extra. We even had drywall that needed to be repaired and yes the installer did that too without any mention of an extra charge. Give Clodette a call, you will be very pleased with both Customer Service and the install team. Oh and they use Canadian Products

As first time home buyers, we knew our 'antique' home would need some upgrades! Great Northern was fantastic. They installed our brand new door flawlessly. We chose the half moon door with a beautiful dark turquoise factory paint. The standard door knob and locks are great quality.
I have to say... putting a new door on an old house made me worry! But the installer matched our crown moulding perfectly, and the outside capping looks super sharp. He was super courteous to my 'night shift' sleep schedule and tried his best to keep as quiet as possible. He took his time and did the job right!
