The answer to any can they sue question is always the same. Yes. Yes, they can always sue (well, they can always sue unless there is an arbitration provision and even then they can sue, it just may not go far).
This is a question of negligence and that is what they will claim in addition to breach and other terms. It will be left up to a professional to review and then up the judge or jury to determine who they believe. The receipt that was signed has little substantive effect on this matter as damage related to claimed construction negligence is never known until sometime after completion of the work, normally.
It is time to speak with a construction lawyer to try to resolve this or prepare the defense. Good luck.
