What We Do

We specialise in replacing your existing single glazed wooden or aluminium windows and doors with new double glazed units. The entire process is simple, maintains the originality of your home as we use the existing timber frames, and provides you with a much warmer, quieter, safer home.

We will come and measure, FREE of charge the windows and or doors you wish to have double glazed so we can provide you with a no-obligation quotation. We will present a detailed written quotation outlining all your options to assist you to make an informed decision.
