Puddling encourages algae regrowth

Best Way to Clean a Concrete Patio in New Orleans

In New Orleans, simply using high pressure may clean the surface but won’t stop organic growth from returning. The most effective approach involves treating algae and mildew first, allowing proper dwell time, then rinsing with controlled pressure to avoid surface damage.

Too much pressure can etch concrete

Soft Washing

Low pressure with cleaning solutions
Highly effective for algae and mildew
Safer for older or worn slabs
