Always create a comprehensive plan to start. Consider talking to an outdoor living designer, deck contractor, or engineer to help with this process. By creating a mock-up and paying attention to specifics before you commit to a contractor or building plan, you'll save yourself the cost and hassle of changing your mind once the project is underway.  When you're ready to hire, getting professional quotes is easy. Browse our deck installation directory for reviews and ratings. Expect any reputable company to give free quotes. But follow these tips:  Never take a quote from a contractor who doesn’t visit the site. Always get at least three bids. Check ratings and reviews. Ask if they’re insured and bonded. Ask to see examples of previous work.
