Pool Deck Cleaning in Harahan, Louisiana: A Homeowner Guide

By Cooper Catalanotto. Last updated September 14, 2026.

A pool deck in Harahan collects a mix of organic and inorganic matter through the swimming season. Algae forms on the damp sections of the concrete, especially in the shaded areas and the spots where water sits after splashing, and it shows as a green or dark film that darkens over weeks. Body oils and sunscreen from swimmers wash off on the deck and leave a film that holds grime and makes the surface feel slick underfoot. Leaves and debris from nearby trees drop onto the deck and sit in the corners and the low spots, where they break down and add to the organic layer. Rust from pool furniture, metal rails or planters leaves orange stains on the concrete, and the chlorinated water that splashes on the deck can leave a mineral film over time. The compact lots in Harahan mean the pool deck is often close to the house, the fence and the landscaping, so what washes off the deck heads toward those surfaces. Understanding what is on the deck is the first step in deciding what kind of cleaning it needs, because the algae, the body oils and the rust each need a different approach.

The slipperiness of a pool deck is the safety issue that makes cleaning a maintenance step rather than just a cosmetic one. The algae and the body-oil film that form on the damp concrete create a layer that is slick underfoot, especially when the surface is wet, which on a pool deck is most of the time. The texture of clean concrete is rough, and that roughness is what gives traction on a surface that gets bare feet and wet foot traffic. When the algae and the film cover the surface, the texture is buried, and the deck reads smooth and dark instead of rough and pale. The risk is a fall, and on a surface that is wet and in use, that risk is real. Pressure washing lifts the growth and the film, and the surface reads clean and rough again, which is the texture that makes the deck safe to walk on. A homeowner who sees a green or dark film on the pool deck should know that it is not just a stain, it is a living growth and a slick layer that is making the surface dangerous, and clearing it is a safety step as much as a cleaning step.

Pool deck cleaning uses pressure washing, because concrete is a hard surface that can take the force, and the force is what lifts the algae, the body-oil film and the grime from the pores. The crew works across the deck in a consistent pattern, holding the wand at a distance that lifts the growth without etching the surface, and moving in a direction that sends the runoff toward the drain or the low side of the deck. The pressure is matched to the concrete, not applied at full force everywhere, because a nozzle held too close can etch a line or leave a streak. The corners, the edges near the pool and the sections under furniture get attention because those are the spots where growth holds thickest and where a broad pass misses. A deck with heavy algae may need a cleaning solution to break the growth before the rinse, and the solution is applied, given time to act, and then cleared by the pressure wash. The work is straightforward, but the reading of the surface is what makes it effective and safe, and the crew adjusts the pressure and the pattern as the concrete changes across the deck.

The pool water is the part of a pool deck wash that needs the most attention, because the runoff from the deck heads toward the pool, and the cleaning solution and the grime should not go into the water. The crew should work in a direction that sends the runoff away from the pool, toward the deck drain or the low side of the yard, and if the deck slopes toward the pool, the crew should contain the runoff or work in sections to keep it from reaching the water. The cleaning solution, if used, should be a type that is safe for the pool environment, or the pool should be covered or the water level lowered before the wash. The skimmers and the return jets should be turned off during the wash to keep the runoff from being drawn into the system, and the pool should be checked and skimmed after the wash to clear any debris that reached the water. A homeowner who points out the pool drains, the return jets and the deck slope before the wash helps the crew work in the right direction and protect the water. The pool is the reason the deck exists, and the wash should not turn the pool into the catch basin for the runoff.

The frequency of pool deck cleaning depends on the use, the shade and how much water sits on the surface. A pool deck in Harahan that is in use through the warm season will show algae and body-oil buildup sooner than a deck that is used occasionally, and the shaded sections will hold growth faster than the sun-exposed sections. A common approach is to clean at the start of the swimming season and once midway through, with the shaded sections checked first, and to move the clean earlier if the film is visible or the surface is slippery when wet. Some homeowners wait until the deck is dark and streaked, and the pressure wash still clears it, but the concrete spends more time under a slippery film than it needs to, and the pool area is a place where a fall is a real risk. The question is not how often a calendar says to clean, but how fast the growth is returning and whether the surface is still safe to walk on with wet feet. A walk-through after a swim shows where the water sits and where the algae is holding, and that is the read that tells the homeowner whether the next clean can wait.

Pool deck cleaning is a surface clean, and it helps to know where the line sits. It does not include sealing or coating the concrete, because that is a separate step with its own products and curing time, and a freshly cleaned deck is the right surface to seal but the sealing is a separate service. It does not include repairs to cracks, spalling or settled sections, because washing does not fix structural damage, and a wash over cracked concrete can drive water into the cracks. It does not include cleaning the pool itself, the pool tile or the pool equipment, because those are separate scopes with their own methods. It does not include cleaning the pool cage or the screen enclosure, because that is a separate surface with its own method. It does not include landscaping work, because the wash clears the deck but does not trim the bushes or the trees that drop debris on it. A homeowner who expects the wash to fix a crack, seal the surface or clean the pool will need to plan those as separate steps, and a wash that clears the grime is the right first step before sealing or repairing. Knowing what the service does and does not cover keeps the expectations clear.

A pool deck wash is best planned around the pool use, because the deck needs to be dry before anyone walks on it, and the pool needs to be checked before anyone swims in it. The wash should be scheduled on a day when the pool is not in use, and the deck should be given time to dry before the furniture goes back and the swimmers return. If the pool water was affected by the runoff, the water should be tested and balanced before anyone swims, and the skimmer and the filter should be checked for debris. The wash should also be planned around the weather, because a rain during or right after the wash can undo the work or send runoff in the wrong direction. A homeowner who plans the wash for a dry day with no pool use gives the crew the time to do the work and gives the deck the time to dry, and the pool area is back in use the next day. The planning is simple, but it is what keeps the wash from being a disruption, and it is what keeps the pool safe and the deck ready for the next swim.
