Q: What should I do if I discover a hidden issue during the work? A: Stop work immediately, document the issue with photos, and issue a "Change Order" to the client for approval before proceeding.

Q: Should I include the cost of permits in the initial estimate? A: Yes, all permit fees and inspection costs should be itemized to ensure full transparency with the client.
