Customer Reviews

Here’s a review from one of their clients:

“We met Julia Dronova at the Red Deer Trade Show where she showed us the product that Window Mart had to offer. We were very pleased with what we saw and how much information Julia gave us. After she came out to our house she took measurements, we discussed what would be the best style of windows for us sand gave us pricing. We thought the amount was reasonable and she had set us up with financing on the spot. A couple of months later the installers came in and they did a great job! We are very happy with our new windows and the service Window Mart’s team gave us. Definitely would recommend this company to anyone!”

And here’s one more:

“Jon was the sales rep that my wife and I dealt with. He was very helpful and an expert on the windows that would work best for our home. All in all we are very satisfied with the product that we purchased. The installation of the windows was excellent and hassle free . I would recommend Jon and Window Mart to anyone of my friends and family. Can’t wait to get our doors picked out and installed next!”

Customer Reviews

Here’s a review from one of their clients:

“We were very satisfied with our experience/relationship with Supreme and it’s representatives. It started with Karl , senior renovation consultant and carried through to the installation done by Zack and Alex. Karl was always available for answering question in a timely manner. Installation arrangements were professionally handled by Heather and Dave. Zack and Alex were always on time and kept us informed with what they were doing, and were open to discussion to any comments we had.”

And here’s one more:

“We had all the windows changed out in our home (29 windows in total). Rick was very helpful with our initial assessment of our home. He was very knowledgeable about the product and was able to advise and recommend changes based on our budget. The 3 contractor crews that came to install our windows were polite and friendly, and pushed to finish all our windows in a timely manner as we were bound by colder weather conditions. Supreme was also great with their servicing department after the windows were installed – they came to perform some touch ups. All in all a great experience, very glad we went with Supreme! Will definitely recommend for the future!”

Customer Reviews

Here’s a review from one of their clients:

“The experience of replacing the windows in our home was very easy and cost effective. The sales associate showed us all the window options and offered ideas that we didn’t even consider (such as a frosted window for our washroom). The windows were made to order and fit perfectly. Comparable companies quoted us almost twice the price for the same product and service. Everything was delivered on time and as promised. The installation process lasted two days. This was expected however, because all the windows in our house were getting replaced at once. The installers were clean, precise and courteous. They covered the work space and cleaned up after themselves thoroughly. This past winter was an even stronger testament to our new windows! Our home is much warmer, there is no draft or condensation and they look fantastic. What’s more, now that we are renovating our home, we needed an additional casing for the window in our kitchen. Econoshield responded to my email in 2 days and had the part in stock and ready. I couldn’t be more happy and recommend Econoshield to anyone looking to replace their windows.”

And here’s one more:

“I had my front window replaced and a bay window installed along with 2 bedroom windows replaced. This was my first magor Reno I’ve done on my house and was terrified of the horror stories of some companies I’ve heard of, the project manager made me feel comfortable with my purchase. I was so happy with their workmanship. They showed up exactly when they said they would, not a minute late and the job was done by the time they had estimated. They were curtious, helpful with the decisions, and did amazing work. Their prices are fair as well!! I would highly recommend this company to anyone wanting new windows!”

“Lillian is a very nice gentleman. Very professional, very respectful and the work is really clean. Lillian and his team replaced the sunroom windows and other windows in our property and the quality is really great. They gave us cost-effective design options. They recommended to replace the rotting studs and siding that was done poorly by the previous sunroom builder. They gave us options and recommended alternatives but did not pressure us. We ended up going with his recommendation to do the work the right way. I will do business with them if needed in the future for my other properties. Thank you Lillian and team!”
