Customer Testimonials

  • Thanks very much again for coming today to insulate, it’s much warmer already! Thanks again, will be sure to recommend!

    Andy, West Hampstead, London

  • Barry is extremely conscientious about the way he goes about installing under-floor insulation. When he did the work in my house he took great care to ensure that the access points wouldn’t be visible once the job was done. He talked me through what he needed to do and where I would prefer him to cut. He kept the access points to a minimum and now he has finished the job I can’t see them at all.

    Ms. H

  • He made the whole job extremely easy for me. He was very tidy and never left any mess for me to come home to at the end of the day. He liaised with Milton Keynes Council to ensure that the work complied with Part L of the Building Regulations and applied for the Building Control Notice on my behalf. All I needed to do was to pay him – and enjoy the benefits!

    I would have no hesitation in recommending Barry to anyone who wanted to have their floors insulated.

    Ms. H

  • Many many thanks for the recent work you have carried out on my home in Wolverton. The new shower room looks absolutely splendid. I keep going in there and thinking “Wow”.

    Ms. C

  • I have every respect for your reliability and professionalism whilst completing this work. It was so good to be able to talk through with you the various stages of the project. I appreciated how you kept me informed and your dedication to the problem solving which occurred along the way. These Victorian houses do seem to throw up the unexpected.
