The house is 10 years old this year and was covered by the NHBC guarantee. We reported the fault 12 months ago. I'm not aware of any warranty from the builders.
Other properties on our development have encountered similar issues with subsidence.
As far as I understand it, a "soft spot" has been identified by the experts that they believe to be the cause of the problem, exacerbated by the long dry spell we had in 2011/12. This same "soft spot" caused subsidence for one of our neighbours, (same builder).
Structurally the house is sound: the raft foundation system has done its job correctly by moving with the ground. There is no damage to the house, but the experts have concluded that remedial work is required.
At this point in time we are not "out of pocket". However the first home insurance premium renewal since the claim was accepted by NHBC is due in June and I'm concerned that it may significantly increase. Equally I can only speculate at this stage what effect there will be on the resale value of the property.
Against whom would a professional negligence claim be made?
