Heritage Windows

York is a city full of historical buildings, beautiful and cultural but also enveloped in heritage-red tape. Vintage windows can struggle to retain warmth and be energy efficient!

Regardless if your home is 1930’s with Casement Windows or a Georgian with large panel sash windows, their visual impact is key to the appearance of the property, and no doubt one of the contributing factors to your purchase of it!

As a homeowner you’ll take pride in the appearance of your property, but, you may also have responsibility for it. If your home falls within the boundaries of a conservation area or is categorised as listed, you’ll have to conform to strict guidelines when undertaking any alterations which could compromise it’s cultural or historical integrity.

This protective legislation can make it difficult to make changes to your home, even essential measures such as improving energy efficiency and insulation. Due to their timber construction heritage windows can be one of the first elements of a property to deteriorate, Georgian or Victorian buildings, exposed for hundreds of years, could be suffering from rot, draughts and be particularly inefficient at sheltering from noise pollution.

These problems may be tackled temporarily with things like shutters or draught excluders but will need a longer-term solution.

Where we can, we will keep your existing frames, painstakingly refurbishing them to withstand modern life.
