Gulfstream Property Services was called to this Jupiter, FL home to perform pressure washing services on a dirty patio. Here we were called to remove mold growing on this patio surface. This project has a wooden trellis above which provides lots of shade to the area below. This makes it difficult for the patio to dry out which makes it a prime target for mildew/mold growth. Here we used the chemical prewash/injection method followed by high pressure cleaning. First, we inject chemical through the wand to wet the surface with algaecide to help loosen and kill the mold. Next, we use surface cleaners to clean the patio. After that we use the wand with a high pressure tip to clean small areas that the surface cleaner can't reach. Finally, we rinse the entire area clean using high pressure.
