“The new box sash windows are superb – both in appearance and performance – and have helped restore the period character to both the interior and exterior of our Victorian property”.

“We chose them having looked at a few local alternatives – and taking into account that they have done quite a lot of work up and down our street.
They did an excellent job for us, reproducing the original specs very closely indeed, matching the existing paint colours and making up bespoke architraves to reproduce the originals.
Overall a great success – the house is now a lot warmer!”
