Gloucester Windows Testimonials


This is our second time we have used Big City Windows and Doors. We had windows installed last year and this year we discovered that there was no condensation on the new windows. We contacted Max Kolosov to arrange the replacement of the remainder of our windows so we won't have to wipe down our windows every day. Got great service on the Estimate, Installation and Cleanup. We even changed the window design on some of them so that both sides of the windows would open as shown. Highly recommend Big City Windows and Doors


What a great experience. Ivan was very helpful in discussing our window needs and explaining details on the windows we selected. Denis and his crew were efficient in the replacement of our windows. They were very respectful in protecting our floors and furniture during the job. Once finished they did a very thorough clean up inside and out. Thank you so much


Big City Windows came by yesterday to replace a bedroom window that had a failed seal. Vadym and his assistant showed up on time and were very friendly. They completed the work quickly and efficiently. I also appreciated the fact that they removed their outdoor footwear before coming in the house (without me asking). Overall I am very happy as the cost of the window replacement came out significantly cheaper than their competitor. I will definitely be calling them back for a quote the next time I need window repair/replacement services. Keep up the great work!
