You should contact an attorney who is experienced in handling contract and consumer fraud matter. There are specific regulations that govern home improvement contractors. If a home improvement contractor violates these regulations or otherwise engages in fraudulent conduct, you may be entitled to treble (i.e. triple damages) and attorney’s fees. We offer free consultations.
I agree that you should speak with an attorney who practices consumer protection law.
Plumbers are required to be licensed.
Check with the NJ Division of Consumer Affairs to see if this contractor is properly licensed.
A town is not permitted to issue permits to an unlicensed contractor. Thus, the fact that he failed to pull permits may indicate that he is not licensed.
If he held himself as licensed, he may committed an act of consumer fraud.
Note, however, that warranty issues are not necessarily consumer fraud.
