Customer Reviews

  • review rating 5  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.

  • review rating 5  Liam is great - did a brilliant job for us a few years back restoring some old sash windows and we have since recommended him to others. Would definitely use again.

    thumb Sam Elworthy
  • review rating 5  Great job speedily done. Liam advised us on how best to use our money rather than up selling us. Will use again, recommended

    thumb jonathan fox
  • review rating 5  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!

    thumb Matt Taylor
  • review rating 5  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!
