I had a wood and brick conservatory that Dunmow Double Glazing took down to the brick and rebuilt completely. I know it was a tricky job because none of the angles were quite right. They did an amazing, professional job and have transformed it into a beautiful living space. I would wholeheartedly recommend this company - Mrs. Griffiths, Haverhill
The old windows were removed any damage to brickwork. The new were made to our design to match a conservatory profile and fitted as requested. Inside plaster was repaired where necessary. Came with dust sheets and covered furniture as required- Mr. Robert Humphrey, Braintree
It is not very often that I have the opportunity to say how delighted I am about work done, so I am going to take this opportunity to say how delighted I am about the work done, so I am going to take this opportunity to tell you about Dunmow Double Glazing Ltd. The work started on time and was very carefully planned. We were presented with an estimate complete with a contract at the very beginning which detailed the work to be carried out and the agreed cost. The work was completed on time and to our expectations. This improvement to our home will definitely increase the value of the property and help with the insulation value too- Mr. Andrew Macgillivray, Braintree
