Testimonials

  • We were keen to reuse our existing frames if possible, and in two out of three sash windows that proved to be the case. Grouting out in situ is a messy business, even done out on a patio, but Jerome and Paul were excellent and expert carpenter-joiners, and took the utmost care to protect the environment from dirt and dust, cleared up assiduously and kept up a cheerful banter throughout the job. It was a pleasure to host them, and now we have a cosy home with smoooothly gliding sashes.

  • Gary and the others were extremely reliable. The job was finished within 2 days (a day quicker than quoted) working late hours to double glaze the windows to my property in Cambridge. When they had to come back for a little adjustment they organised it within hours. We are very pleased with the outcome both in terms of insulation and looks. I would recommend Sash Window Preservation without hesitation.
