You definitely should consult an attorney for resolve on this.
I am sorry that happened to you. In the future, if you have home inspection items, I like to advise my clients to resolve them with a credit to the buyer at closing. If repairs are left up to the seller, more likely than not the buyer will not be satisfied. With a credit, the buyer can have the work done by people they trust to the specifications they want. No misinterpretation of language. Just make sure you have 3 estimates for the work that needs to be done. You don't want to be surprised by an unanticipated Pandora's box of problems.
Best of luck to you.
Based on your responce to my answer, it would appear that you let the time frames on the accepted offer as they relate to home inspection items expire. Time is of the essence and if the negotiations of home inspection items run past the dates in the offer you need to agree to extend the time frames or you are out of contract.
