I used Cutting Edge LLC (http://www.cuttingedgellc.net/index.php) in Virgina to design and install an entire patio and front walkway for my Shaw townhome. I can’t recommend these guys highly enough. When you call, ask for Kevin Schmauder. They are much more than just landscapers; they demolished the existing patio and walkway, built retaining walls/planters, ensured proper slopes away from the house to prevent pooling, and came up with several other creative solutions for my space. They are extremely responsive and professional. Please let me know if you need any additional information on them.
