Our extensive restoration services are underpinned by a dedication to quality and the satisfaction of our wonderful customers. We are grateful to have worked on so many unique properties over the years. It is our pleasure to realise your ambitions, in every restoration project.
From the whole team: we thank you for your loyal custom. Restorative work is our passion and without your commitment to preserving important heritage details, we simply could not achieve what we do.

Here are just some examples of the kind words we receive:

Jill and John, St. Albans:

It was a very pleasant, stress-free experience having your lovely team here. We’re absolutely thrilled with our windows. They are completely transformed and we are both so relieved that we didn’t have to go for UPVC. Thank you all for your hard work and for making our little home feel happy again. Warm regards, J&J xx

Ms. Bird, Project Manager, Watford:

Sash Windows Hertfordshire completed full restoration works on four, period properties which I own and manage. They worked professionally to my difficult time schedule and very kindly accommodated a number of my own unexpected obstacles without batting an eye! They exceeded my expectations in every instance, and I look forward to continuing our work for my next project.

Edward K., Stevenage:

Fantastic service. Great company with amazingly talented crew. I’m feeling very smug and content typing this from my office with my new double-glazed sashes. The draught-proofing, servicing and repainting on top has changed how I feel being here. Couldn’t be happier. Highly recommended.

Mr. & Mrs. Barton, Hitchin:

A splendid job well done!!! 5 stars. Our daughter is incredibly impressed and envious of our gorgeous windows and will be calling you to do hers in the new year!!

The Cheswick Family, Hertford:

Thank you to all the staff at Sash Windows Hertfordshire for your patience and friendly service. Our home feels and looks absolutely delightful. You went above and beyond. Please make sure you call by for a cup of tea next time you are all working in Hertford 🙂


On behalf of my Mother, I wish to express sincere gratitude for the services received. Restoration works of the highest standards, with utmost care taken when working on what is a particularly challenging heritage property. Heartfelt thanks, R. Giles.
