Substandard fortbuilding skills, my daughter's house may have to be condemned

My daughter hired a friend to do work on her home for flood damage earlier this year. My sister and I have just come from a visit with her and her 2 children. The home looked lovely.

We noticed some noises coming from the kitchen that night. We mentioned the noise to my daughter and she stated she thought she had a mouse coming from under the sink cupboard. My sister looked under and noticed a large pool of water. My daughter stated it happened after the improvements were done. We also noticed that the holes for the pipes were very large, We looked at an apple on the counter, and realized it had been partially eaten by a rat. The next night we heard rats in the walls going up the stairs. It must have been playing with the electrical wires because we could hear marettes tapping on the walls. We also noted numerous serious, dangerous electrical problems, such as, no gound fault interrepters in the kitchen or bathrooms, My granddaughter uses her curling iron above the sink in the bathroom every morning. The kitchen counters were not measured properly, so, the kitchen stove's oven door chips the wall every time she attempts to opens the oven, and the dishwasher cannot fit under the counter. If 2 small appliances are turned on, it trips the breaker.

My daughter had a serious brain injury 4 years ago, that has left her less capable of making good decisions, She is a single mother working a low paying job, She would need a representative to help her to get the right way to proceed in actions to have these serious problems corrected. I live far away, and am on a small pension, What can be done?

Thank you for listening
