Simple process. The techs came out and seized the windows and got them installed successfully! Very happy!

Installation crew was excellent. They were well organized, courteous and efficient. They finished the window installation project a day ahead of schedule to avoid exposing our home to the coming bad weather. They did an excellent job of clean up. We had nothing to clean up when they left.read more

We were very happy with everyone associated with this project. The installers were very experienced, very professional, very meticulous, and perfectionists. They worked twelve hours straight on the second day without even taking a lunch break. The result -- our windows are beautiful! Unisson has good reason to be proud of their work ethic, their strong skills set, their attention-to-detail, and their warmth and friendliness.read more

My neighbor recommended this company when I wanted to replace the windows on my property. They gave me plenty of choices for new windows, most of them reasonably priced. It took about two days to complete the work which was quicker than I had anticipated. I am very happy with their service.read more

We wanted to replace some of the windows in our home as they had gone out of shape. We were looking for windows in the same color and style but had difficulty finding the right ones. My wife called this company and spoke to Olena who told us that they had the design we were looking for. Their servicemen came later and replaced them within hours. Everything happened so smoothly we were pleasantly surprised. They charged us a very reasonable rate too.read more

I can only speak highly of this company. I changed 7 windows and front door this year, over $11,000 with a lot of extra requirements, which were all respected. All my windows and front door was painted a special color (not standard), some of my windows had pet controlled screening (in the baseman) which was an added request after contract been signed and some of my front windows had thicker glass than standard for noise reduction. Before and after service was excellent and i would recommend them to anyone. Installation guys were very helpful, explaining some of the questions i had along the process. A+read more

We replaced all of our windows and our slider. The windows and the door are outstanding products. The people that we worked with were terrific. They were so nice, knowledgeable, and did a professional job. They cleaned up completely after they were finished, and they showed us how to operate all of the windows, the slider, and all of the screens. We couldn't be more pleased with the results they gave us.read more

We recently employed Unisson to replace our doors and windows, which were in bad shape. They gave us a quote, which was lower than the other three Montreal companies we had approached. The quality of their service was top class, however. Very impressed!read more

This place was a horrible. They charged $65 for a 1ftx 2ft net. Don't go there.

We needed new windows. Our 100 year old house still had the original windows, it was not good for our hydro bill, and we were rarely able to open them to feel a breeze! Unisson doors and windows came highly recommended and the reviews were positive. We looked through the brochure, and really liked the options for window choices. Got an estimate done, in a timely manner and booked the installation date. A few weeks later, the contractors arrived and did a review of the home and window openings to see what they were up against. I was expecting the price to change because the age of the windows and the complexity of working on an old house (old brick etc.) but there was no change in price. I still had my hesitation about how the installation would go, again you never know what to expect with these old houses. When the day came and the contractors arrived with the custom built windows the contractors were polite and very friendly and they got straight to work. In one day they were able to do all 11 windows, cleaned up after themselves, took all of the garbage and old windows with them, and they really exceeded my expectations of how the windows would look and how the install would go! The windows themselves are very big, clean, and are clearly built with care and pride. We are very satisfied with the work that was completed!read more

Exercise caution when dealing with this company. I find them less than honourable. If you are planning to use this company for your project, make sure that the contract you will sign will include EVERY detail agreed to during their sales pitch.Here is our experience with them. When their salesman, Mr. C, visited my sister’s home in Oka QC to get the info to provide us with a quote, I specified that we needed pet (resistant) screening for the patio door and he agreed to this requirement. I wasn’t present when they visited my sister for the contract signing (a project of over $5000.00). Of course, they did not include this. When I contacted Unisson to get the screening replaced with what had been verbally agreed to, they replied that this requirement was not mentioned in their file. They offered to replace it at a cost of +$200.00 to my sister. Of course, we are not going to give this company another cent.read more

I was looking to replace my windows with something fancier to go match the exterior look. I called their office and the secretary who was very friendly and explained the choices in detail. Their crew arrived at our home later and helped install the windows which were perfect. They made the whole process quick and easy.read more

The job is done perfectly. Installation is very clean and nice. The installers are professional and nice people. They did all that was promised and was in contract. They explained every step of the installation and answered all questions. We were concerned with the bow window and double door installation but all went extremely well. There was no need to be worried. A truly remarkable installation team. Thank you very much Unisson Windows.read more

The company is really responsible for their job and responsive. It only took me a phone call to report a minor problem and a chain reaction followed: my request was registered, followed up, an installer came by and fixed the problem. This happened more than 2 years after the initial installation with no questions asked! Thank you!read more

Horrible company to deal with. They are very nice before you hand them their money. Once they have your money they take it and run. Zero after sales service, big mistake on our part, lesson learned. Had problem with three of my windows that they installed. They blamed everything on my house which was renovated from a-z and not their work!! Buyer beware!!!read more

i used this company to install about 9000$ of windows on my house in april 2015, where 3500$ went towards a bay window. the installation was pretty fast, on what they had actually installed that day. they didnt take the right measurements on the bay window so the windows that they made were the wrong size, they only realized this when they have already taken out half of my existing window. so what did they do? they put the old window what was left of it, back in with pieces of wood sticking out everywhere as shims. it obviously looked horrible but i thought it would be very temporary, well it was temporary for about 3WEEKS! when they came to install the bay window it took them a day but they didnt finish it properly, the caulking looked horrible, and was just falling off all the time, the underside of the bay window looked like a kid put it together. it wasnt finished properly so they said they had to come back. a few weeks went by before they called me randomly and said they were ten minutes away and they would work on it. they didnt make an appointment, just called me out of the blue. when i got home from work i checked it and again it looked horrible. this went on for months before they got it to look half decent, and by now it was september and we noticed some water was coming in from some of the windows on the bay window. it wet the wooden piece where we sit on and the molding. the person tells me that its fine and the product are raw products so they wont get mold or mushrooms! yeah right. anyways in october i had redone my soffit on the house and the worker showed me the insulation that was put in the bay window, it was a measly little square piece that didnt cover much. what a joke. i kept calling them every now and then and they still are reluctant to come fix my water issue, in december of 2015 i get a visit from one the workers and showed him the water infiltration and he said they will look into and contact me back. it is now january 21 of 2016 and i havent heard from them, i called them three or four times, and left emails, texts, they never respond. when i did get someone on the phone, they said they will forward this to the owner and get back to me. guess how that went. from april 2015 to january 2016 i still dont have a proper bay window that i paid 3500$ for. too many mistakes for one window. read more
