We completed on our house sale last week but had had contentious buyers all the way along. Just when we thought everything was over, we have had a letter from their solicitor with various points that they have come across since moving in and are unhappy with. Is there anything they can do at this point or now we've completed is it too late? They had a full home buyers survey done and we rectified all the problems that threw up, they are now saying we've had two major leaks in two of the bathrooms and have covered them up by painting them over (something we are completely unaware of), they say the gas fire shut off is covered with electrical tape and not working (again nothing we were aware of, we had the gas fire serviced at their request prior to exchange and it passed with flying colours!). Any help would be appreciated. Many thanks.
