We have a situation where we have paid out 112 thousand on a home improvement project on a 145k job. The contractor was terminated due to many reasons but primarily poor craftsmanship. When we were asked to settle the paperwork is so poor neither the contractor nor us as homeowners can come up with a number. What kind of professional can evaluate our case? Binding or non binding arbitration is not in the contract nor is there a mediation clause. We want to be fair, but no one can figure out what the 112 went towards. There also are 6 change orders to consider.
