Testimonials

  • Thank you so much for the wonderful job that the sash window team did for us in here in Bedford. All of the team worked so hard and seemed to do a thorough job, very tidy and made the whole process as easy and professional as possible. Thank you all for a wonderful job.
    — Sarah & Simon Blair, Bedford
  • We are very pleased with the refurbishment of our windows at Thurlow House, and the works carried out by Gary and the team.
    — Mr Hall, Badwell Ash, Suffolk
  • The remade sashes are beautiful, with the division bars as fine as I could have wished and the slim double glazing units quote inconspicuous. I was so impressed by the work done by the carpentry and fitting team.
    — Mrs Hannaford, Norwich
  • They nursed me through the planning process (grade II listed) and despite them being in Norfolk and me in West Devon, sent a team of 7 who worked incredibly hard and left no mess, who completed the task of four sash and two modern windows, in one day. I can't recommend them highly enough. But perhaps increased warmth and much reduced external noise is recommendation enough.
    — Mrs Susan Hall, Devon
  • Fantastic way to double glaze and maintain character of house. The work was carried out with great efficiency and on time. The lads were a pleasure to have in the house. Immediate elimination of draughts and increase in warmth. Strongly recommend without reservation.
    — Mr Albert, Norwich
  • The work was carried out on time with minimal disruption. We're so glad we chose to have the windows renovated rather than replaced as the character of the house is maintained but with much improved noise and draught insulation.
    — Mrs Bond, Norwich
