  • Wall insulation advice and potential cost.

    Some where there is a problem with JTE Smartenergy LTD.
    I arranged a WC Insulation job at my house in Nottingham, the survey was done by two good engineers and a price was agreed to get the job done.
    Then a problem arose for JTE in trying to contact an extraction team to remove the old residual filler in the wall. I said to Amy and Megan that I was prepared to wait providing it could be done before winter 2022.
    In June 22 I had not heard any thing so sent emails to ask for progession , no reply. I have tried and tried to call but the phone is continually busy and I can not get through. My only choice is to cancel this job and try with another company who are contactable, a pity as I do want the job done as the price has been agreed, but no one is contactable !!!!.
