Although I am not licensed to practice in Texas, I suggest that your daughter's position depends on what she wants to do? If she has a year's lease is it worth while fighting? If it is month to month, then she can just terminate at the end of the month. Were these repairs made part of the written lease?
You would have to read the statutes as to withholding rent. Certainly, she has to make written demand for each item; the two weeks unearned rent, the repairs etc. Only after a reasonable time has passed without action by the landlord, can she claim "constructive eviction" and give notice that she is going to leave.
