Local experts in Retrofit Double Glazing

Upgrade with the retrofit specialists

Glass and Window Solutions are well schooled in updating existing, aluminium, single glazed windows into cost effective double glazed units. We have vast experience in these types of projects. It is a relatively simple process that involves us replacing the original beads and sashes with new double glazing profiles.  

When all existing single glazed windows in your home are replaced with Glass and Window Solutions double glazing you will notice an immediate change in the environment. Your home will be warmer, quieter and more cost effective to heat in winter. And there’s a massive reduction of annoying condensation, so common in homes with single glass panes.

During the few years of working with Glass and Window Solutions, on my rentals and our own home, I have found all of the staff to be extremely helpful and considerate. Overall, Glass and Window Solutions are good. One point to mention is that they use superior materials in comparison to many other double glazing companies. I will continue using them, since they all know me and their friendly and professional advice has always given me marvellous results. Thank you Glass and Window Solutions.
