Professional Concrete Cleaning in Atlanta, GA
Concrete is the most common hardscape material in the Atlanta metro area — driveways, sidewalks, patios, pool decks, retaining walls, curbs, and commercial walking surfaces are predominantly poured or stamped concrete. While concrete is durable, its porous surface absorbs stains, traps moisture, and provides a textured substrate where algae, mold, and lichen establish colonies. Over time, what was once a clean gray surface becomes a patchwork of black mold streaks, green algae film, red clay staining, oil spots, and tire marks.
Rare Earth Ltd specializes in concrete cleaning and restoration for both residential and commercial properties across metro Atlanta. Our commercial-grade surface cleaners and hot water systems deliver results that consumer-grade equipment simply cannot achieve — uniform cleaning without streaks, deep stain penetration, and biological kill at the root level.
Concrete Surfaces We Clean
- Sidewalks and walkways — Residential and commercial pedestrian surfaces cleaned to remove slip hazards, gum, and embedded dirt
- Patios and outdoor living areas — Poured, stamped, and exposed aggregate patios restored for entertaining and outdoor dining
- Pool decks — Non-slip concrete and cool-deck surfaces cleaned to remove algae, sunscreen residue, and chemical staining
- Retaining walls — Block, poured, and stone-faced retaining walls cleaned to remove efflorescence, algae, and dirt staining
- Stamped and decorative concrete — Cleaned at appropriate pressures to preserve color, pattern, and sealant without damage
- Curbs and parking bumpers — Commercial curb lines restored for property appearance and code compliance
- Steps and stoops — Front entry and rear patio steps cleaned to remove slip hazards and restore curb appeal
- Garage floors — Interior concrete floors degreased and cleaned. Popular before epoxy coating application
Atlanta-Specific Concrete Challenges
Concrete in the Atlanta area faces a unique combination of staining agents that require targeted treatment approaches:
- Red clay (iron oxide) — Georgia's signature red clay creates rust-colored staining that penetrates deep into concrete pores. We use specialized acid-based treatments that dissolve iron oxide without damaging the concrete surface
- Black algae and mold — The dark streaks and patches found on shaded concrete throughout Atlanta are biological colonies that standard pressure alone only removes from the surface. Our biocide treatments kill organisms at the root so they do not return for months
- Pollen accumulation — Spring pollen season leaves a yellow-green film that, if left to bake in summer heat, bonds to concrete and becomes a permanent stain. Early-season cleaning prevents this
- Tree tannin staining — Oak, maple, and sweetgum leaves leave dark tannin stains on concrete. These organic stains respond to oxidizer treatments that break down the tannin molecules
- Rust from irrigation — Well water and some municipal water sources in metro Atlanta contain iron that creates orange rust stains around sprinkler heads and drainage paths
Our Concrete Cleaning Process
- Surface assessment — We identify the concrete type, stain types, and condition to select the right cleaning method and chemicals
- Pre-treatment — Problem stains receive targeted chemical treatment with appropriate dwell time before mechanical cleaning
- Surface cleaning — Rotary surface cleaners with adjustable pressure deliver uniform results across flat areas without the zebra-stripe pattern caused by wand-only cleaning
- Edge and detail work — Expansion joints, wall edges, corners, and obstacles receive hand-wand attention
- Hot water treatment — For oil and grease stains, we use water heated to 200 degrees to break petroleum bonds that cold water cannot touch
- Post-treatment rinse — Final rinse ensures all cleaning agents are removed and the surface is ready for use or sealing
Concrete Sealing
After cleaning, we offer concrete sealing services that protect your investment. A quality penetrating sealer prevents future stain absorption, reduces algae growth, and makes ongoing maintenance easier. Sealed concrete looks better longer and requires less aggressive cleaning in subsequent years. We apply commercial-grade sealers appropriate for your specific concrete type and exposure conditions.
Service Areas
We provide concrete cleaning across the entire Atlanta metropolitan area including Stone Mountain, Decatur, Marietta, Roswell, Alpharetta, Sandy Springs, Dunwoody, Tucker, Lawrenceville, Kennesaw, and surrounding areas.
