Whitfield Plumbing has contracted with Moreno Valley Homes to do the plumbing work for a new subdivision Moreno is building. Whitfield has agreed to do the plumbing, including all three phases required for homes: the initial connections in the foundation to city water supplies, the pipes once the foundation and farming are complete, and the final installation of sinks and toilets. Under industry practice, plumbing companies are paid $3/4$ of their contract price once phase two is complete. Whitfield's total price per home in the contract with Moreno was $$16,000.$

Whitfield completed phases one and two for all of the homes and was paid $$12,000$ per home by Moreno. Whitfield then told Moreno that it would not be able to complete the third phase unless he was paid an additional $$1,000.$ Hiring a new company to step in and take over phase three for the homes would cost Moreno about $$6,500$ because the company would have to determine what Whitfield had already installed and then match the plumbing fixtures to that design. Moreno had to have the homes completed on time in order to secure closings that were needed to pay off its construction financing. Moreno agreed to pay Whitfield the additional $$5,000.$ Do you have any suggestions for Moreno in terms of his rights under the contract and whether there is any way for him to recover the additional $$1,000$ from Whitfield?
