Custom-Built Retaining Walls in Mt. Airy, MD

Good retaining walls start with a solid plan. HL Design Landscaping looks at grades, soil conditions, drainage paths, and how you want to use the space above and below the wall. We then design wall lines, heights, steps, and any integrated seat walls so you gain usable, comfortable areas instead of just a steeper slope with blocks on it.Call or text us @ 301-829-9323 or request a FREE Quote to get started.
