Sorry to hear about your problem. Unfortunately, the term contractor is a very lose ended term and should never really be associated with a carpenter. Typically this is because as the name implies they "contract" out most of the work to more qualified people, not to mention anyone who works under a binding contract is referred to as such and really makes no statement to the qualifications that they hold. If you would like I could try and stop by this weekend or on Monday either before or after I help Slandis move his tank. Just shoot me a PM and let me know how to contact you by phone and where to find ya. The big problem is that without knowing the layout of your house it is impossible to give any sort of reliable option to the situation.
