Our contractor will not repair a leak in the siding he installed. (siding did not pass inspection)He states he did not know about it until 3 months later (not true) so it's not his problem. But we told the inspector at time of inspection. Contractor also states we cannot hire anyone else to repair it. Can we call the subcontractor he used? I am sure they do not know about the siding problem. At one time they gave us their business card for future work.
