    What Our Clients Say

    Kate at the Calgary Window Mart was in training when she came to my house. She did a great job explaining how the windows are made and the important aspects that I should consider when choosing my windows. I appreciated that she wrote notes and left them for me so I could explain the windows to my bf (windows are more complicated than I thought!!). The price of the windows is good and I look forward to seeing how the installation process goes and my new windows!
    Window mart Michael Romankov is my go to man he's been here at my home, gives me the best service, if you're looking to replace windows or doors, Michael is the man you need to contact.Dale
    Just to say we had a wonderful experience dealing with Windowmart for the change of all our 21-windows from single glaze to triple glaze. The Project Manager Ivan Ranyuk was extremely helpful and patient with us for a decision making that has taken us over 1-2yrs by this June 2022.However, the processing and execution took a very processional turn that has literarily transformed our house by 06-Oct to a very highly heat conservative building overnight. We couldnt have it better, just in time before the first snow 22-Oct. A good number of our neighbours watched in amazement the 2-days installation operation and came for inquiry. We trust their patronizing Windomart soonest.We say a big thank you to Windomart and a bigger thank you to Ivan for his tenacity and courteous marketing with simplicity and professionalism that earns our respect. Kudos and more grace.
    Excellent price, service, and turnaround time for ordering in high season
    Just closed the deal with Mikhail, one of the salesman. He was great. Explained everything to us and made sure we got the best for our house.
    Great service, very friendly and willing to go the extra mile. Thank you very much Mikhail Mezentsev.
