Window Mart Reviews

We just had Denys Zhadan from Window Mart come by to discuss new windows for our home. His professional attitude and practical outlook made the design an ordering process a pleasure. we had a budget in mind when we decided to move forward and he came in right where we expected it should. Denys was excellent at communicating all the particulars involved for what we wanted done and we are looking forward to the install later this summer.

I needed my old basement window to meet egress code. Denys came to my home and was great to work with. He broke down all my options and gave me a quote that was so much lower than a competitor that we decided to do a 2nd window as well.

After receiving 3 different quotes, we have chosen Window Mart to supply and install 6 windows in our home. Our Project Manager is Denys Zhadan. His professionalism and prompt responses were very much a deciding factor for us, as well as cost. We changed our mind 3 times throughout the process, and he was very patient, knowledgeable and accommodating. Once our windows have arrived and been installed, I will update this review, but so far, we are very impressed with Window Mart !

We are renovating a home in Midnapore and already had a quote from a different company, but when came and showed me Window Mart’s product, I liked the quality right away and a couple days later signed with Ivan after he worked with his manager on a good deal for me.

Working with Ivan made it an easy choice for us to go forward with Window Mary for the replacement all of the windows in our home. Ivan was very thorough with his explanation of the features and benefits of Window Mart windows. I also appreciated Ivan’s punctuality and quick responses to my emails. Looking forward to getting our windows installed.

I have been working with Julia Dronova to pick out and place a custom order for the 20 windows (1 custom window) and 4 exterior doors (1 custom door) for a new home I am building. She is very professional and listened to my vision of what I wanted. All 24 pieces ordered will be custom painted, delivered and installed by Window Mart. Hopefully the delivery and installation goes as smoothly as the ordering.

We had the pleasure of meeting with Julia when she came as a consultant to talk to us about upgrading our windows. We were both very impressed with her as she walked us through the process we would require including; the time frame for manufacturing and installation, the cost and the discount we were given. She is a very polite and professional lady and her presentation was excellent. We will definitely recommend her company to our friends.Tim & Linda Penney

An excellent and educational presentation. The Project Manager, Ivan Ranyuk was extremely helpful, informative and patient with our questions. He took the time to explain everything in depth and made sure we understood all of the details about their products and timelines. We are looking forward to having our new windows installed by Window Mart in the Beddington area.

Julia Dronova came to my place to give me a quote on replacing my windows. She was courteous, on time and professional and understanding. I was impressed that she knew the products well and was able to give me a quote quickly. She also understood what I was looking for. I hope the installation and product lives up to her recommendation. The final measurements have yet to be done but I am sure they will be correct.

Good experience with Ivan from Window Mart on helping me get my remaining basement window replaced. I had a special request to have it coated with maximum solar protection because of light sensitivity, and he included this upgrade at no extra charge. Great service that I would recommend to everyone.

Had my windows installed April 19. There were several issues. One of the windows was measured wrong so they could not replace and had to re-order and there were some deficiencies in the trim work. Window mart was quick to respond and comeBack to rectify the deficiencies to my satisfaction and I am happy with the results. I would give 5 stars if not for one window being measured incorrectly and the finishing work not being done properly the first time. I would recommend them and believe they offer good value for money and care about maintaining customer satisfaction.

Our windows have not been installed yet but if the installers are as knowledgeable and easy to work with as Denys Zhadan there will be no problems. Denys answered all our questions and gave us the necessary information to order the windows which we wanted. Pricing was also very much in line.

We received quotes from two other companies before Ivan from Window Mart came to our home in Saddletowne to provide his quote. He took much more time to go into a lot of detail about the quality of their product, which was very educational to me and my husband. After some negotiation on the price, during which Ivan was on the phone with his manager helping us to get the best possible deal, we signed with him, confident that we would be getting greater value than if we went with any other company.We will be recommending Window Mart to our friends.

I'll update this review through the process. So far, window mart was prompt to get back to my inquiry regarding a quote. Alex Alexeev came to my house with all appropriate PPE and was very professional while doing the quote and explaining the products. He didn't pressure me at all, and seemed quite upfront about cost and quality. Within a few days of me agreeing to the quote, I was contacted by the office for official measurements. They were prompt. I'm waiting for an installation date.

Alex was prompt with both appointments. He had to come out the second time for more measurements, as I forgot about a window I wanted cut out and installed. Very knowledgeable about the product he is selling & thorough. I will give an update once the windows are installed. Thank you Alex

Ilya came by the place today. Super informative. Came promptly. Gave us a great quote and we pulled the trigger on our window job. Definitely great customer service by Ilya. Will update when window is done.Update: (6 Months later) Finally after waiting all winter, window mart came and installed my window. Alex did a phenomenal job. Everything from the trim inside and outside the house. He nailed it out of the park. I would defiantly request him if you get the chance. Other than the long wait time, it was defiantly worth it. Thanks

My house in Arbour Lake is 25 years old and all the 15 windows really needed replacing. After reviewing the services of several window replacement companies in Calgary, I decided to go with Window Mart. Ivan R, Window Mart's Project Specialist, provided a very good overview of the features of the windows they offer. The innovative features of their windows were very compelling. He took the time to explain the pros and cons of various choices I had and the warranties Window Mart offers. I was very impressed with his knowledge. And, the total cost he provided for the 15 windows was close to what I was expecting and very competitive. I am looking forward to enjoying my new windows once installed.

Have just signed a contract with Window Mart to have windows and a door replaced. Our salesperson was Denyz Zhadan who was great in every way. He showed up right on time and presented us with the information we needed to make a decision. He did not pressure us in any way at all and just presented us the info and the merits of their product. We made several changes after the initial appointment which he handled professionally and patiently. The price was lower than 3 other quotes and quality is same or better than the others. Will update as the process moves along.

I had a new 5 pane bow window installed in 2020 with triple pane glass. It is a very good window and kept the cold out. It is also tinted so sun does not heat up the room. Andrey was very good at estimating was pleasantto deal with and very professional. Today I have him back to estimate replacing 3 more windows. He gave me a reasonable price and Windowmart will be installing them for me too. I have 2 windows left to replace and next year I am sure they will be back!
