Our contract read as follows: "The owner agrees that the owner or owner's invitees shall have no direct contact with any sub-contractors hired directly by the contractor. Any questions to the plans requested by the owner must be directed to the contractor not to any sub-contractor hired by the contractor. Sub-contractors hired by the contractor are hired at cost plus overhead and profit. "The contractor, sub-contractor, and suppliers costs are confidential and subject to overhead and profit." We had no direct contact with any sub-contractor and we were never provided documentation of time nor materials. The only thing we received were bills for work completed. We never had any idea that this work was completed at reasonable or customary rates. Whether we paid a just price for our house will always be a mystery. But, according to this contract that is apparently the way the builder wants it.
