If you don't know someone reliable, it's not always easy to identify the most competent contractors and designers based on first impressions. That's why you should follow a strict protocol whenever inviting someone into your home to provide a service.
-Seek trusted recommendations
-Never accept an in-home visit from an unrequested solicitation at your door, on the phone, or via email
-Make your first visit/inquiry on their premises, so you better understand their operation
-Get references and visit those references for inspections and questions about work done, cost and payments
-Insist on a contract that spells out working hours, material quality, due dates, payment schedules and quarantees.
