It went well. Jory Bailey arrived with the door, installed it, did some carpentry repair around the threshold, and took away the old door. I was glad that he was able to do this on the schedule that we had agreed to. He kept in touch about the plan, his ETA, and the cost via text and phone.

General contractors are the ones that coordinate home construction projects. They are in charge of the day-to-day oversight of the subcontractors to ensure that the project is completed on time and to resolve problems as they arise. General contractors:

Complete pre-construction planning, both with the customer and crew
Provide realistic cost estimates
Develop construction timelines
Ensure deadlines are met
Acquire permits as needed
Purchase supplies and materials

Before hiring a general contractor for your home project, it’s a great idea to write down a list of questions to discuss with each prospect. Some example questions to get you started include:

Which types of insurance do you carry?
Can you provide a list of references?
What is the expected timeline for this project?
How will my project be supervised?
Will you hire subcontractors for the job?
What is the best way to communicate changes?
Will you obtain all of the required building permits?

Be sure to check our state licensing tool to review the local general contractor guidelines for your area.

As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:

The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review

Yes, most general contractors require a down payment for project completion. A reasonable down payment for a contractor is 10% to 25% of the total project cost, though that will vary based on project size and location. The down payment helps cover the upfront costs of materials and permits and helps ensure payment for the project at hand.
