One would need to read the contract but without doing so i can make these suggestions. If there was money held back in escrow then you can make a claim in escrow. If not you can ask them to replace these items. When you say you closed escrow did yo not take posession of the property? A letter from an attorney may pursuade them to pay. You may be required to go to mediation or arbitration depending upon your contract. We along with alot of other attorneys will give free consultations so you may want to seek an attorney to review the contract.
