One of the best sources for tricks of the trade home repairs that I have ever found, have been books on home repairs and remodeling. These books can often be a valuable source filled with amazing tips that can save you time and that ever so precious dollar or money.
If you really want to learn the valuable tricks of the trade, you're probably going to need to find a professional with the experience who is willing to teach you these valuable tips or tricks of the trade. Most of the time, the people who have the experience, aren't willing to share it with others.
I myself have learned plenty of these tricks of the trade from other professionals that I worked with, while we worked framing homes with other professional master carpenters. These master carpenters often were unwilling to teach me anything, but by befriending them, I learned more than I would have never learned at any university or school.
If you don't know anyone with the experience and most homeowners don't, we need to refer back to the books and some of these books are written by experienced master carpenters who understand the value of these tricks of the trade. Like myself, I rarely give them away, however I have written quite a few articles about them. Every once in a while, I let one loose and your reading one right now.
These books can be found at your local library or purchased at a community bookstore. They have been a wealth of information for myself and others for years now. If you really want to learn the tricks of the trade, quite a few of them can be found by reading home repair and remodeling books. If you look hard enough, you will usually find them.
