Hi Vicki. There's at least 3 lessons here that you probably have picked up on by now. First one is to use your own contractor agreement, wherever possible (I believe there's a good example in the BP FilePlace). Secondly, secure your funding before you start work. Stopping/suspending a project due to a lack of funds is hard to recover from, for both you and the contractor (especially from a scheduling perspective). Third, estimates for labor, time and materials are always best guesses, which can change for a multitude of reasons. Accusing a contractor of overcharging, without firm facts and figures, is tantamount to accusing him of stealing and that never goes over well. If it were me, I'd send him a letter with whatever data you have to support your claim and ask him for whatever you think is a fair settlement. This would at a minimum, document your attempts to resolve the dispute, should you ultimately decide to go to small claims court. The best outcome from my perspective is to secure the funding you need and have him complete the job within the original contract price. Good Luck. - Marion
