Pool Deck Cleaning
Slip-safe, algae-free pool decks and surrounding hardscapes that look brand new — making your pool area safer and more inviting.
What Is Pool Deck Cleaning?
Your pool deck is supposed to be the place where you relax, not where you worry about slipping. But in the Carolina heat and humidity, pool decks are prime real estate for algae, mildew, and mold. Constant moisture from splashing, combined with warm temperatures and often partial shade from nearby landscaping, creates the perfect environment for organic growth. Add in chemical buildup from pool water, hard water scale from the hose, and the daily accumulation of sunscreen, food, and foot traffic, and your pool deck can go from pristine to slick and stained faster than any other surface on your property.
The danger isn't just cosmetic. A slick pool deck is a real slip-and-fall hazard — especially for kids running around the pool, guests with wet feet, and anyone carrying a child or a tray. Algae and mildew create an invisible, almost frictionless film on wet concrete that you can't see but can definitely feel when you step on it. That's why pool deck cleaning isn't just about looks; it's about safety.
We clean pool decks differently than driveways. We have to protect the pool water from debris and runoff, avoid blasting chemicals into the pool, and work carefully around pool equipment, skimmers, and returns. We use the right pressure for the deck surface — whether it's stamped concrete, plain concrete, pavers, or stone — and we treat the algae and scale that make the surface slick. The result is a pool deck that looks brand new and, more importantly, is safe to walk on with wet feet.
Why It Matters
Slip-Safe Surface
Remove the slick algae and moss film that makes pool decks dangerous — especially for kids and guests with wet feet.
Removes Pool Chemicals
Clean away chemical residue, scale, and hard water buildup from pool splash and hose water.
Restores Color
Bring back the bright, clean look of stamped, colored, or plain concrete that's been dulled by organic growth.
Protects the Surface
Gentle, effective cleaning preserves your deck's finish, sealer, and decorative texture without etching.
Improves the Look
A spotless pool deck makes your whole backyard look resort-ready and more inviting for family and guests.
Safe for Pool Water
We work carefully to keep debris, runoff, and cleaning residue out of your pool — protecting your water chemistry.
How We Get It Done
A proven, step-by-step approach that protects your property and delivers spotless results — every time.
Protect the Pool
We shield the pool edge with barriers, cover the skimmer, and divert runoff away from the pool water to keep debris and residue out.
Pre-Treat Algae & Scale
We apply a targeted treatment to break down algae, mildew, and hard water scale, giving it time to work before we pressure wash.
Surface Clean
Our commercial surface cleaners clean the deck evenly and deeply — no zebra stripes — at the right pressure for your specific deck material.
Detail Edges & Joints
We hand-clean expansion joints, edges, corners, and around pool fixtures — the spots the surface cleaner can't reach.
Rinse & Recover
A thorough rinse washes away all loosened grime and algae, and we redirect the rinse water away from the pool to protect your water chemistry.
Cleanup & Inspect
We remove all barriers, check the pool for any debris, and walk the deck with you to confirm a safe, spotless finish.
Surfaces We Clean Safely
We match the method and pressure to the surface — protecting your property while delivering a deep, lasting clean.
Safe For
- Stamped and colored concrete pool decks
- Plain broom-finished concrete
- Concrete pavers and travertine pavers
- Natural stone (flagstone, slate) pool decks
- Tile pool surrounds and coping
- Pool deck coatings (acrylic, kool deck)
Clean With Care
- Decorative acrylic or kool deck coatings — we use lower pressure to avoid damaging the texture
- Sealed pool decks — we test a small area to protect the sealer before cleaning the full surface
- Travertine and natural stone — we use a gentler method and appropriate cleaner to avoid etching
- Tile pool coping with older grout — we avoid high pressure that could loosen or damage the grout
- Decks with existing cracks — we reduce pressure and flag any structural concerns
Time to Call Gates?
If you've noticed any of these around your property, it's probably time to schedule a cleaning.
The deck feels slick or slippery underfoot, especially when wet
A green or dark tint on the concrete that wasn't there before
White chalky scale or hard water deposits near the pool edge
Dark mildew or black spots in shaded areas or along joints
Your pool deck looks dull or grey instead of its original color
Kids or guests have slipped or nearly slipped on the wet deck
You're opening the pool for the season and want it to look brand new
It's been more than a year since the deck was last professionally cleaned
How Often Should You Schedule This?
For most pool decks across the Carolinas, we recommend professional cleaning once a year — ideally in spring, before pool season kicks off. Heavily shaded decks, decks with heavy use, or properties near large trees may benefit from twice-yearly cleaning. If you have a decorative coating or sealer on your pool deck, annual cleaning helps preserve that finish, and the sealer should be inspected and reapplied every 2–3 years. A clean, sealed pool deck is easier to maintain, safer, and looks better all season long.
