In Argentinis v. Gould, 219 Conn. 151, 592 A.2d 378 (1991) the Court stated: "Generally, when a builder breaches a bilateral construction contract by an unexcused failure to render substantial performance, he cannot maintain an action on the contract to recover the unpaid balance of the contract price because substantial performance, a constructive condition of the owner's duty to pay the balance, has not been satisfied." Id., at 157.
