It is important to let your builder know up front that you intend to have the work inspected by an independent third party construction expert. This will help set a tone with the builder and let them know that you expect things to be done properly. Ideally, you will want to start communication with your inspector as soon as you sign a contract with your builder. It is recommended that have a professional inspection of the foundation prior to the pour. A follow up inspection should be conducted after the foundation has set up.
