What will matter here is who your contract was with. Your post makes reference to the director's home and a company cheque, but the detail matters.
If your contract was with the director and he tried to pay you with the company's money, then it's the director who owes you payment for the work and you'd sue him.
If, on the other hand, the company hired you to do work on the director's home, then it's the company you'd sue.
I appreciate that with personal companies like this it may well be difficult to know exactly who the contract was with, especially 5 years down the line.
Also please be aware that if you do have to sue the company, depending on their asset position you may find it very hard to actually get the money out of them, especially if they liquidate.
