Summary & Key Takeaways

• The case involves a building company, Jacob and Youngs, contracted to build a summer home for the homeowner, George Kent. The company installed some pipe made by other manufacturers instead of the specified Reading manufacturer.

• Kent discovered the error and demanded the plumbing to be redone. Jacob and Youngs refused, so Kent withheld payment of $3,483. The court examines whether the installation of Reading pipe is a constructive condition for the duty to pay and the measure of damages for the breach.
