Everyone of us value our time. Therefore, we are grateful to those who value our time. We are very pleased with the service provided by the installer Aleksandr Sinyakovich. Despite the weekend day, he arrived a few minutes before the scheduled time, and exactly at the appointed time, he rang our door. Alexander made all the required measurements, gave us the necessary explanations, answered all our questions. We were pleased that thanks to Alexander's punctuality, we did not have to change our Sunday's schedule. Thanks to Window Mart for such staff.

Contacted Window Mart and they promptly set up appointment with us to review our needs. Ivan came to our house prepared to assess the project, spent a fair amount of time reviewing what exactly we wanted and then quoted our replacement door & windows. It was a pleasure to work with Ivan as he was knowledgeable and did not pressure us to make a hasty decision. We are looking forward to our new door and window unit. Will update when job is complete

I have yet to decide whether I will be proceeding with the installation at this time, but I must say at this point I am very impressed with the professional attitude of Ivan Ranyuk who came to my house to give me a quote. He was extremely informative and I did not feel any pressure, which to be honest was a breath of fresh air considering some other window companies that I have used prior.

Ivan our sales rep was so easy to work with and very detailed with what Window Mart provides to its customers and followed up with any questions made the process easy to choose - Ivan was top notch on his sales presentation. The installer Igor his work is incredible I was amazed on the perfection and his detail to what he does. Very respectful cleaned up after himself and was such a delight to have him do our windows. Customer service needs to step up to the plate and more communication from the service department with future delays but overall highly recommend Window Mart! Just loved the product especially the whole house being done - great job guys!

Window mart responded to my inquiry very quickly. They were easy and flexible to arrange a time for a quote that fit my schedule. Kate, the project specialist, came to provide a quote and go over their product and the various options. I'm quite satisfied with her professionalism and product knowledge. The pricing quote was comparable and what I was expecting for a custom window installation. Besides a high-level of professionalism, there is also a human-touch to window mart. I am replacing a large living room window due to accidental breakage. Knowing that it was a large & unplanned expense, Kate was able to work with me on options to pay the deposit and get my order started right away. So far in the process, I'm very happy with window mart.

When you go to improve your house you want the best and for a reasonable cost. This is exactly what you get. In addition we've received a "small lecture" and presentation by Maxim Saybel. He explained us all nuances which impact on aesthetic, energy saving, insulation and much more and helped to finalize our wishes and order the right windows for our home.

Nikita was very helpful in explaining every detail related to the quality and installation of the windows. He knows what he speaks about and added to that, he has the experience himself of an installer which gave us even more confidence. He is very personable and easy to deal with and I would highly recommend asking for him when you phone Window Mart.

I have had Window Mart in the past to install a door and was pleased with the results.This time around we are installing new windows at our farmhouse and appreciate what the salesman has done for us.Petro drove over an hour to the house and even stayed late in order to finish the agreement. He is also very knowledgeable with the products and patient with the little indecisiveness we had.Now we wait until warm weather again to have the windows installed and look forward to the finished result! Thank you!

I had to replace 4 windows and a sided door. Was worried about the prices go up. Window Mart project manager Andrey helped me to find a good deal according my financing situation and the work to be done. He was very detailed on the presentation of the company products and the whole process of work. The instalation was scheduled for early spring. My impression was: professionalism, respect for clients, high level of professional communicatin. Looking forward to see the results of instalation.

Our home needed all windows and doors replaced. We called window mart and they immediately set up an appointment to come to our home where other companies said we were too far out. We met with Ivan and received a complete presentation on the process, the manufacturing quality and especially the 25 year warranty. He was flexible on some financial aspects which led us to begin the process. It's a big worry taken off of us. We look forward to the actual install and improving the anesthetics of our home! A sincere thank you to Ivan! If you live in Champion or Southern alberta it would be worth the call!!

Today, my dad had Ivan Ranyuk in to do a quote on his windows and doors main floor. This gentleman is professional, courteous, efficient, and prompt. We are in Red Deer, so having him willing to come out was a huge plus. He gave us a quote as soon as he was done the measurements and making sure we understood the quality of this all Canadian made product (I love Canadian made) for 8 windows and doors, the price is amazing and honestly our mind is at ease with the the long term warranty these come with. So happy

We wanted to update our review after the installation of our windows was complete… we’re still thrilled!Our window installer Marcel was beyond amazing! We have a 1908 home so each window was unique and unpredictable; Marcel was so patient and did a fantastic job; his sense of pride in his workmanship is extremely evident. He was punctual, communicative and skilled. From beginning to end, we were very pleased with our experience with Marcel and Window MartWorking 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 knew nothing about windows until Ivan came by to my house in Bridlewood this evening and explained everything pretty clearly, making it easy to understand for someone like me. I am sold on the quality of the product and would love to replace my existing worn out drafty front windows with Window Mart's top of the line ones.
