New sash windows and sash restoration.

About the project

We installed new Accoya double glazed sashes into five windows.  We fully restored the original boxes and installed the new double glazed sashes into the original boxes. We also fully restored four original timber sash windows and two casement windows.

The benefits will be increased thermal performance and heat insulation. Plus, no more noise and rattles! The windows now open and close smoothly and easily and they replicate the original sashes, so keeping the traditional look and feel of the property.

What our client said

Our client was delighted with the final result providing us with a fantastic Checkatrade score and review.

Teddington New Sash Windows and Restoration

Where do I start? Thank you for a job well done. However it is a bit more than that. It is a big thanks to you Melissa for being friendly, involved, knowledgeable, keeping us informed, engaging, and dealing with changing circumstances ( none of it your doing - but your responsibility to juggle). Enormous thanks to you Dan for being you, committed and passionate about  your product service and staff. And finally a big thanks to your craftsmen who delivered on all your promises, but not only that the manner in which they did. Always punctual, polite, professional and tidy. I have to confess I rarely leave reviews on products/services, but you are a rare exception and have done so on Checkatrade. And you also have the honour of being the first and only company to date I have awarded 10 out of 10 across the board for."
