Miller Pattison insulated my elderly mothers loft/pipes/cold water tank some three years ago.Unbeknown to us my mums ball cock valve on her cold water tank had a drip leak,ordinarily not a problem as most of them develop a drip leak,and when there is somebody living in the house and the water is being used daily, nobody is aware of it and the leak never gets as far as the overflow pipe.HOWEVER,my mum was very ill and it was decided she would stay with my sister for a period,leaving the house unoccupied.My brother took her to my sisters and didn't think to turn the water off ,pre-occupied with my mums health.the drip leak over a period of 10 days built up within the tank,got to the overflow and ran throught it straight into my mums loft,because the Miller Pattison fitters had forgotten to re-attach the overflow pipe to the tank after removing it to fit the cold water tank jacket.I have phoned the head office 3 times over a two month period,and was promised an inspection but so far nothing.I e-mailed the local branch and they haven't even acknowledged my e-mail.Had to get the plumbers in (costly),and had to redecorate the ceiling myself.My mum has Alzheimers and doesnt understand about the problem with the cold water tank,she thinks the water came in through her roof,and now everytime it rains she thinks her ceiling is going to leak and lays awake worrying.Avoid this company at all costs they are rubbish people.
