What Our Customers Say

"Really happy with the secondary glazing that Rick installed for us. He made sure everything was done properly and left neat and tidy and the noise reduction and temperature improvement is much better than we expected. Thanks for a nice job and would definitely recommend."

Jamie Odell

"Dunmow Glass replaced 3 of my old windows and did an excellent job. Two lads arrived on time and quickly removed the old windows and cleaned up the whole area. The new windows were installed efficiently and everything conformed to my order. The foul weather, wind and rain, didn't stop them working continuously."
