How to deal with contractors/know the right prices and makeovers?

[Galit Garsiel]

Contractors will suggest the most expensive makeovers. How do you know which are necessary and which aren't? How do you know if you can get a cheaper window frame or cheaper floors, or if the money you spend on the window frame is even worth you awhile? Maybe the money you're going to spend is higher than what you get in return, won't raise property value enough to justify the investment.
