Here are some questions you may want to ask a general contractor before hiring them for a project:

1. What is your experience and background in the industry?
2. Can you provide references or a list of past clients?
3. How do you handle scheduling and project management?
4. What is your process for communicating with clients during the construction process?
5. Do you have a team of subcontractors that you work with regularly?
6. How do you handle changes or modifications to the project scope or budget?
7. Do you have experience with projects similar to mine?
8. Do you carry liability insurance and worker's compensation insurance?
9. How do you handle any issues or problems that may arise during the construction process?

It's also a good idea to clarify the terms of your agreement, including the payment schedule, timeline for completion, and any warranties or guarantees.
