Although our main showroom is located in Hockley, we are able to cater for our clients as far east as Shoeburyness, as far North as Braintree and we even service clients inside the M25 in places such as Chigwell and Romford. We now use the internet and can find out about the size and location of your property by using Google Earth, to enable us to provide rough estimations for any double Glazing requirements.

However, we would advise potential clients to actually spend time in our showroom in Hockley and get to see the materials that we use with our double glazing, conservatories and doors. Understand that if you would like to have a home of high standards, then it’s wise to make sure the extension is made with modern highly durable building material.
