Money is power.
Contractors are much less interested in making you happy after they have been paid in full. Some less reputable individuals will present many seemingly plausible reasons why you should pay them now instead of waiting until the end project. Do not be pressured into paying early.
Prices that seem too good to be true, usually are too good to be true. Many homeowners have regretted their decision to act on a “great deal” that turned into a bad deal.
Do not buy from an unknown company selling door to door. Some contractors have well-rehearsed, door-to-door scams designed to quickly separate you from your money.
Resist the high-pressure sales technique. Some companies often offer “today only” incentives to encourage the homeowner to make a decision on the spot.
