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.

03/03/2021It 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.

18/04/2018We met Liam last year and were instantly drawn to his open and honest demeanor. He was very helpful in giving us practical advice on what he thought would work and outlined in detail the options and choices that we could consider. We were delighted to find that not only was he the more experienced option, but also that the quote offered was considerably more competitive than all the other sash window specialists we saw. We went ahead and had 8 brand new sash windows fitted, and 7 existing windows fully reconditioned & draft-proofed, as well as a couple of casement windows and a balcony door refurbished. The quality of the work was outstanding and we are over the moon with the new windows - the craftsmanship and finish is excellent and the house is quieter from outside noises and was definitely warmer / less draughty over the winter! Liam and Paul were both incredibly professional and very communicative, even though we were often working from home whilst they worked they were very accommodating and kept us updated on progress. We are already planning to have them back to refurbish and double-glaze our back door and another casement window 🙂 I cannot recommend them highly enough. Thank you for everything Liam and Paul!
