DIY vs. Call a Pro
Retaining walls under 3 feet tall are manageable DIY projects using interlocking landscape blocks. Excavate a level trench, add compacted gravel base, stack blocks with construction adhesive, and backfill with drainage gravel behind the wall.
Call a professional when:
Hire a professional for walls over 3-4 feet tall (may require engineering and permits), walls supporting structures, walls on steep slopes, or natural stone walls requiring skilled masonry.
