Retaining Wall Installation Marietta

How Much Does a Retaining Wall Cost in Marietta?

Most retaining walls we build in Marietta and Cobb County fall in the $25–$50 per square foot of wall face range. The final price depends on the wall's height and length, the material you choose, how much excavation and drainage stone the site needs, and how easily equipment can reach the work area. Walls that hold up a driveway or need an engineered design cost more than a short garden wall.

We give every Marietta homeowner a written estimate after looking at the slope in person, so the number reflects your yard instead of a guess. Call 678-541-1222 to schedule a visit.

Do You Need a Permit for a Retaining Wall in Marietta?

Often, yes. In most metro Atlanta jurisdictions, walls over about 4 feet tall (measured from the bottom of the footing) or walls that support a load like a driveway, structure, or another slope need an engineered design and a building permit. Permits in Marietta are handled by Cobb County or your city's building department. We confirm the requirements for your address and coordinate the engineering and permit when a wall needs it.

HOA neighborhoods usually require architectural approval for a new wall, including the material and color. We provide drawings and product samples so your HOA can sign off without delays.

What Makes a Retaining Wall Last in Georgia Clay?

Most walls that fail in North Georgia fail because water was never given a way out. Saturated clay pushes hard against a wall, and without drainage it will eventually lean, bulge, or crack. Every wall we build includes:

Excavation to firm soil and a compacted gravel leveling base
Clean drainage aggregate behind the wall instead of native clay backfill
A perforated drain pipe at the base that outlets water away from the wall
Geogrid reinforcement layered into the backfill on taller walls
A slight setback (batter) into the slope on every course
Capstones secured with adhesive and grading that sends surface water away

Retaining Wall Materials for Marietta Homes

Natural stone and stacked fieldstone suit Marietta projects, especially wooded or older properties where a wall should look like it has always been there.

We also build stone-faced walls, seat walls around patios and fire pits, tiered terraces with planting beds between them, and stone steps that cut through a wall. If you have an old timber or railroad-tie wall, we remove it and rebuild with a material that will not rot.

Signs Your Marietta Retaining Wall Needs to Be Replaced

Call us if a wall on your Marietta, GA property is leaning forward, bulging in the middle, cracking, separating at the corners, or has soil washing out at the base or through the joints. Rotting timbers, standing water behind the wall, and a wall that moves after every storm are also warning signs. Small problems are easier and cheaper to fix early, before the wall lets go.
