I am so happy with the excellent service and my beautiful new windows. Michal is an expert and his crew worked in a professional, efficient, organized manner resulting in an impressive installation. In my kitchen i had a quartz windowsill (a design element installed by a previous contractor) that prevented the window from closing. Michal said they would take care of it…and they did! They were able to cut the quartz to the proper size and reinstall it, as a courtesy!! I got ten windows at a GREAT price. I highly recommend them!!! New windows for an old house are amazing…you can see, feel and hear the difference. Great investment and energy efficient! Thanks Michal and team!
