Hi, My name is Philip. I am an attorney with over 16 years experience. Hopefully I can help you with your legal question.
What you describe, if the contractor damaged your property in the course of completing the contract
? Then the contractor is liable for the damages incurred. Example: Say that there was a contract for $10K, and in the course of completing the contract, the contractor damaged your property to the tune of $2K? That would allow you to demand that the contractor either repair the damage caused or to reduce the fee by an amount to allow you to have the damaged property repaired.
But to require the contractor to repair the damages, or reimburse you for the cost of the damages, you must give the contractor notice, in writing, and an opportunity to correct the problem.
At this point, consider drafting a letter to the contractor that details the damages they caused. Also consider including a bid or two from a separate contractor contractors that gives a repair cost of the damages. Photographs can be good as well, to document the damages (in case you have to go to court, photos can be very helpful)
If they try and sue you, and you can prove they caused the damages, the court will require them to pay for the damages before they can be paid on the contract.
But you want to put this request in writing and give the contractor the opportunity to correct this problem to solidify your court case.
Please let me know if you have more questions...happy to assist if I can
