How much can I ask our contractor to pay for the cracks in the bathtub he caused during our bathroom renovation?

Your contractor should have liability insurance to cover damage caused to your property in the course of doing his work. This insurance company may be willing to cover the cost of repalcing the tub based upon such a negligence claim. However, the insurance company may also argue that the "repair" is all you are entitled to. Depending upon how good of a repair can be made, they may be right. You should get the opinion of a third-party contractor as to how goood of a repair can be expected to be made. It is my opinion that you will have trouble getting the the cost of replacement, unless an acceptable repair can not be made.

In any event, you should determnine if the contractor has insurance and place them on notice. You should have better luck with them, than your contractor directly. Retaining a lawyer in your situation would be helpful, since a letter from an attorney will show that you are serious, that you have someone on your side who knows the law, and you will not be taken advantage of. Insurance companies comonly try to take advantage of claimants to save money for their company.

I hope this answers your question, and good luck in resolving your legal matter.
