I currently have a contractor building a detached garage. It has been a challenge making sure he is complying to the signed contract. He has taken short cuts before consulting me first. He is unprofessional and is doing shotty work. What can I do?
The most important thing would be to follow the contract. If it provides for certain notice or giving leeway for the contractor to cure, you will need to follow those provisions. You should be able to terminate the agreement if you desire and follow the provisions for doing so.
