When the contractor and subcontractors come to size up your project, listen to the way they talk to each other. You can get a sense of how well they respect each other and work together.
Don't plan a vacation during your project. It is just not a good idea to leave contractors to work on their own. Even with builders you trust, it’s better to be available. Questions will inevitably come up and it is in your best interest to be available to discuss how you would like each issue/situation/option resolved.
It is a standard practice to hold some money back until the project is fully completed. The final payment should be held back until the final walk-through has been done and all items noted have been fixed.
Why is it so important to hire a licensed contractor?
From the California Department of Consumer Affairs website:
“Unlicensed operators pose a risk to you and your family's financial security. They expose you to significant financial harm in the event that a worker is injured while on your property, or if your property is damaged. Few, if any, unlicensed operators have bonding or workers' compensation insurance. The quality of their work usually doesn't compare to that of a licensed contractor. Don't take the chance in order to save a few dollars. You'll probably end up paying more in the long run.”
