I have a legal question. I worked for a Contractor on a hardscape job installing concrete bench seats, seat walls, and fireplace hearth tops. All constructed from 12,000 psi countertop custom mix with scrim. We met with the homeowner to choose color options. Once the homeowner chose we begin the project. When all of the pieces where ready the homeowner insisted we install them immediately, ( we advised them it was to early because there was still significant construction going on) the contractor told us to do it so they would be happy . After installation the contractors men dropped numerous stone from 20' off scaffolding breaking our pieces in various areas. There was a lot of neglect after we left the job. All of the work we performed was paid by the CONTRACTOR and our contract was with the CONTRACTOR with no warranty. The homeowner is now trying to sue us (the subcontractor ) to replace all pieces or refund them 1,800.00 . The homeowner never paid us a penny ,or was under contract with our company. Does this have any validity in court.
