  • “Your young workmen have just left my house after re-lining our chimney.
    I thought you would like to know what a great set of lads these are. They appear to have made a good job of the chimney and pot. Left NO mess, were polite, professional, friendly and worked constantly whilst they were here. I thought it would be quite a stressful experience, but I have to say it was anything but.
    I will also recommend you should I hear of anyone wanting their chimneys doing.
    The lads seemed to enjoy their work and all said they liked working for your company so you are obviously a good boss. Well done. Once again than you and thank the lads”

    SKIPTON

They explained the job and how it would be carried out, they showed much respect to my Mums concerns and explained in detail what they do and how they do it, they also were very considerate to her house and furniture making sure that all the carpet and furniture was covered up and they even cleaned up after themselves. The team that did the job are a credit to your company.
    Once again thanks for a great job I will certainly recommend your company to anyone”

They have left everything spotlessly clean and, above all, have been thoroughly nice people. Please pass on our thanks to them, they are a credit to your firm and you should be proud of them.
    Thank you for the excellent service”

    YORK
  • From the time I first contacted Thermocrete, on the recommendation of a friend, I was impressed with your response and attitude. This view continued when Matthew came and did the appraisal through the various phone calls, and ultimately when Martin and Andrew came along.
    Your men were presentable, polite, co-operative, and eager to please, and they seemed to be right on top of the job. They were also scrupulously tidy, in what I am sure could become a messy operation, and yet they left the site more tidy than when they arrived. What is more, Thermocrete’s quote was very competitive with those of the metal liner people. Many thanks”

    LEEDS
  • “Dear Sirs, May I say how impressed we were with Martin and Paul. From the moment they arrived they never stopped working, not even to have a sandwich. They left no mess whatsoever.
    Two very nice and polite men and I would have no hesitation whatsoever in recommending them and your firm to anyone who would wish to have their chimney lined. You were also right Matthew, the house is much warmer and the fire works far better than before. Once again thanks for a job well done”
