Double Glazing, Windows & Doors in Chelmsford & Great Dunmow

Amazing customer service from start to finish had my new front door & bi fold door installed today by Graham... read more & Tom. Good quality doors and I love the Agate Grey colour door.

Tom and the Team recently fitted my new windows and patio door. The process was very each from start to... read more finish. The original quote was very reasonable, and they seem to be very good quality. The fitter, Graeme, was incredibly respectful of our house, and seemed to take great pride in his work.

Even after three and a half years, the staff here went above and beyond to fix a small issue we... read more had. We had patio doors and windows fitted right at the time we had our first baby. It was a hectic time and the Certass certificate went awry. We are now moving but need the certificate. I spoke to Tom on the phone and he went above and beyond to do some investigating and secured us another certificate from Certass at no extra cost! Thank you Tom, appreciate it!

We would like to thank Tom and his team for the service and professionalism when carrying out installation work on... read more our new porch. They installed a new front door with side panels and a big window to the side and it looks great! There was a small problem with the glazed unit in the door which after site visits, videos and various attempts to get round it, suggested by the suppliers, was replaced as it was a production problem their end. Tom chased it up for us and persevered until we got the outcome we wanted which was a replacement unit. I would recommend Dunmow Double Glazing to anyone thinking of having replacement windows or doors. A very good and professional company.
