Angie's List says the best customers are aware of what they want, understand their budget and are willing to take suggestions.
Creator of Angie's List, Angie Hicks, said to remember that companies aren't mind readers.
"The key to a great company-consumer relationship is communication and that requires great communication from the consumer side, too," Hicks said. "Be sure to tell them what you are looking for, what you like, and what you don't like. Be considerate, but be great communicators."
When working with any company or contractor, it's important to voice your concerns and expectations. If you decide to change an aspect of your project, remember there may be financial ramification involved. The contractor may have already ordered materials and booked employees to work, so the cost of your project may increase if you decide to change things mid-stream.
Angie's List says it's important to be open and honest with contractors during the hiring process. Keep them updated, and let unsuccessful bidders know when you've made your final choice. Don't worry that you're offending them; it's much more polite to give service providers the information they need to move on.
