The simple way to deal with condensation, heat loss and rising energy costs

Secondary glazing in an excellent means of insulating your home without having to undergo extensive work on your windows, making it ideal for those looking for a more budget-friendly alternative to double-glazing, as well as owners of period properties.


The addition of an extra, slim-line window to the inside of your existing window will help keep the heat in, keep condensation at bay and reduce the volume of outdoor noise.

We also carry out glazing repairs.

It’s the affordable option

Secondary glazing allows you to benefit from improved levels of thermal efficiency, soundproofing and energy efficiency – for less! Ideal if you’re not in a position to have double or triple gazing installed.

Ideal for
listed properties

Live in a listed property or heritage building? You may not be able to install double glazing. Secondary glazing is the ideal solution, preserving the character of the original windows whilst offering improved insulation and energy efficiency.

Reduces condensation and heat loss

Having an extra layer of glazing means the condensation associated with single glazing will be significantly reduced. You’ll experience fewer draughts and less heat loss, making for lower heating bills.
