thanks for all your help, i have a quality fitter going in shortly,the carpet is a brintons bell twist and i now realise what caused the problem i think.
my machine unknown to me during the job lost one of the vacuum pumps and while continuiong to put water in was not takimg it out in sufficent volume although the carpet at the end of the clean dident seem, overly wet, it must have been and with the upholstery also drying out the combined moisture level was just too much even trhough i had air movers on...also the gripper in one area had only been laid on double sided tape....onto the concrete..i have a feeling this is going to be a big loss, but perheps the fitter with his power stretcher can win the day. cheers Bev
