I've been using Sash Window Specialist for many years now and I can honestly say you won't get a nicer bunch of guys. They have done all sorts of work for me in two different houses. From glazing replacements, sash unit overhauls/replacements right the way to providing me with bi-folding sliding double-glazed doors. I honestly love these guys and will continue to use them and recommend them to friends and family!

It is now a year since Liam fitted our first double glazed sash windows in our five sitting room windows. A friend wisely advised us to have one room done first. We were so pleased with the result that we had all the other twelve windows replaced. We live in a conservation area and it was important that the new windows looked exactly the same as the originals. The work was completed so efficiently and so neatly that we cannot recommend Liam and his company highly enough. We survived the cold spells of this winter with our thermostat set several degrees lower than in the past. On stormy days, we no longer have any rattling windows.

We were delighted with our sash windows. Liam and Paul refurbished the majority of windows in our house, and created new sashes to replace modern metal frames and to use in our extension. They were pleasant, extremely knowledgeable and did a great job at a great price. We have had no problem with the windows in the five years since, and they still delight us. We recommend them highly.
- Matt Taylor
We're very happy with the new windows that Liam and his team put in. Very good communication, very timely updates (pictures in e-mail sent during the manufacture), quick and hassle free installation. We've been passing on their details to any of our friends that need good quality window replacement. Highly recommended!

Liam and Paul have just fitted replacement double glazed accoya sashes in fifteen of our windows. The quality is fantastic and they are excellent replicas of the original windows - except without the drafts and condensation. Liam was really responsive to our initial enquiry and visited to measure up and also provided some good advice and guidance. They both have a real eye for detail and their craftsmanship is excellent. We changed our minds on some of the window furniture and they even dropped by and changed these free of charge. We were all working or studying from home whilst they fitted the new windows and they were really considerate. We couldn’t recommend them highly enough and we are absolutely delighted with the end product.
