In that case, have my apologies :-). The honest answer is no, you don't have a strong case. The basic precept is that the contract must have been substantially completed. This does not mean 99% or something, it means 100% complete with minor defects. The remedy for such is then contract price awarded, minus the cost of altering the defects. What is substantial is a matter of fact dependant on the contract type, what the defect is (E.g 90% complete of a boat is mathematically substantial, but the 10% might be the missing hull, which is the essence). However, you should seek to further your claim on the precept of Planche v Colburn [1832] whereby it states that where one party prevents fulfilment of the contract, the other party may claim in relation to work already done, as here. The reason I state that your case is shaky is because I don't know the original dispute; if it was caused by your husband, then the courts would take a dimmer view of who is actually preventing the contract's continuance. What was the original dispute over, if I might ask? Also, do you have proof of the agreement, something to the effect in writing?
