Working with Pros

   Sometimes the situation calls for a pro. For instance, many communities require a licensed professional to design or install some features such as tall decks and retaining walls, swimming pools, and structures that shelter people.
   If your plan calls for complex changes of grade, you'll definitely want an expert to help you avoid problems like flooding or erosion. Your landscaping job may be so big that you'd rather leave parts of it to a specialist. Or, before building, you may want aesthetic advice.
