About McCullough

We build from the ground up — literally.

McCullough Landscaping specializes in retaining walls and hardscape construction across Suwanee and greater Gwinnett County. We understand the unique challenges of building on Georgia's red clay — from drainage engineering to proper compaction — because it's all we do.

Every wall starts with a real site assessment. We evaluate your grade, soil composition, water flow, and load requirements before a single block is set. That's how walls stay standing through Georgia storms, not just the first season.

What We Build

Hardscape, done right.

Retaining Walls

Engineered for Georgia's grade and clay. From gravity walls to reinforced segmental systems — sized to your site, built to hold.

Patios & Walkways

Natural stone, pavers, and flagstone — laid on a properly prepared base with pitch for drainage. No settling, no pooling.

Outdoor Steps & Stairs

Grade changes handled with stone or block steps that tie into existing walls and walkways — not tacked on as an afterthought.

Drainage Solutions

French drains, catch basins, and grading corrections that protect your hardscape investment and keep water where it belongs.
