Customer Reviews

  • 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!

  • Great job speedily done. Liam advised us on how best to use our money rather than up selling us. Will use again, recommended

  • Liam fitted replacement double glazed sashes to my property back and front and I have been delighted with them. I had old secondary glazing in the front which was ugly and did not do the job. I now no longer have condensation dripping down the windows and the house is quieter and warmer. After doing some research into specialist companies I am so pleased that I chose the Sash Window Specialist. Liam is very knowledgeable and the work carried out was done with the minimum of disruption. My new windows have transformed the house. Very happy with the Sash Window Specialists and would certainly recommend without hesitation.

  • 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.

  • 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!
