If you want to see the material that go in home improvement there all there. If the first guy you talk to doesn’t know what he talking about try another, someone should be able to help you. The library of books at the front is pretty good. Keep the big picture in mind you want do it yourself instead of hiring a contractor or learn about the material used in home building and purchase some material without a contractor markup. My brother is contractor he laughs at people who don’t know what things cost. He takes some tile of a wall and gives a b.s. excuse to gut your bathroom. Knowledge is power and the books in the front are well detailed, these guys back off when they see you know how its done. In any case stay away from guys without a land line, unmarked van/truck or offering time and material contracts. Get a referral from a friend, everybody’s done a couple of good jobs at fair prices even the crooks.
