We have recently had some work carried out by builders in our home in Haute Vienne, which was completed satisfactorily. However, since completion the company has been put into liquidation. What we want to find out is if there is any organisation which help people in these circumstances, especially if we find anything wrong with the work which has been done. Our understanding is that the work is guaranted for 10 years but we do not have a "certificate" for the works carried out.
