We compared 18 waterproofing companies in Atlanta on Google Maps · 5 listed · How we rank

Water in a basement or a musty crawl space rarely fixes itself, and the waterproofing companies in Atlanta that handle it hold more than 5,400 Google reviews between them, all rated 4.8 or higher. None of these companies lists an office inside the city: they work from Marietta and Norcross, and one lists no address, so the real question is who covers your side of town and which kind of job they are known for.

Short answer: AquaGuard Foundation Solutions North Atlanta in Marietta has the largest review base here, a 4.8 rating across more than 3,300 Google reviews, followed by Trotter Company in Norcross (4.9, more than 1,100 reviews) and CGS Waterproofing & Foundations (4.9, more than 510 reviews). Reviews describe basement waterproofing, crawl space encapsulation, French drains and foundation stabilization.

How the scores work

Rating is each company’s live Google star average. Review volume is how many customers have rated it, ranked against other waterproofing companies in the Atlanta area. Confidence weighs the rating by that volume, so a 4.8 from thousands of people carries more weight than a 5.0 from a couple of hundred. Recency reflects how recently customers are still leaving reviews. No business can pay to change these numbers.

What drives waterproofing costs in Atlanta (2026)

Waterproofing jobs range from a small drain fix to a full interior system or a crawl space encapsulation. Price follows the size of the area, whether the water enters through walls, floor or ground, whether digging is needed outside, and whether the foundation itself needs stabilizing. Get at least two written estimates that name the method, and ask what the warranty covers.

Waterproofing across metro Atlanta

These companies work from Marietta and Norcross, with one built around Lawrenceville, and their reviews mention homes and condos from East Cobb to Gwinnett. Searching for basement waterproofing near me? Each listing shows a phone number and directions, so you can start with whichever sits closest.

What to ask before waterproofing

  • Where is the water getting in, and how did you find that out?
  • Is the fix interior drainage, exterior drainage, a crawl space system or foundation work?
  • Does the quote include a sump pump, and who services it later?
  • What does the warranty cover, and does it transfer if I sell?
  • How will you contain dust and restore the work area?
  • Is an engineer involved if you suspect a structural problem?

Frequently asked questions

Do these Atlanta companies handle crawl spaces as well as basements?

Trotter’s site lists crawl space drainage and encapsulation, Leader’s site lists encapsulation, repair and vapor barriers, and a CGS customer had a crawl space encapsulation redone alongside a radon system. AquaGuard customers also mention crawl space repair.

How do I know whether cracks are structural or just a moisture problem?

Ask for an engineer or a documented inspection. A Trotter customer said an engineer visit found their cracks were not structural, though crawl space encapsulation and drainage were still recommended, while an AquaGuard customer’s annual inspection found the house had sunk and needed stabilizing.

Which of these waterproofing companies are closest to East Cobb or Gwinnett?

The Waterproof Group and AquaGuard work from Marietta, and a reviewer places The Waterproof Group in East Cobb. Trotter and CGS are in Norcross, closer to Gwinnett, and Leader’s site is built around Lawrenceville.

Do waterproofing companies in Atlanta offer warranties?

Trotter’s site advertises lifetime warranties and a reviewer mentions one. The other companies’ sites and reviews don’t spell out terms, so ask for the warranty in writing and what it covers.

Where to start

AquaGuard is the most-reviewed name here and fits jobs that mix water with settling or concrete. Trotter suits crawl spaces and drainage. For a basement leak close to Cobb, The Waterproof Group and Leader are worth a call. Get the method and warranty in writing.
