About This Project
This outdoor shower area in Hingham had seen years of heavy use and zero cleaning, the pavers were covered in a thick layer of green algae, organic debris embedded in the joints, and significant discoloration across the entire surface. The drain area was especially bad, with dark organic staining radiating outward from the center.
Outdoor shower pavers are one of the toughest cleaning jobs because they stay wet constantly during the summer and are often shaded, exactly the environment where algae and mold thrive fastest. Without regular maintenance, the growth compounds season over season.
The Challenge
The joints between pavers were packed with organic material, a mix of algae, decomposed leaves, and biological buildup that had been compacting over multiple seasons. Standard pressure washing would remove the surface growth but leave the joint material intact, and the regrowth would start immediately.
The pavers also had a textured surface that required careful technique, too much pressure and you erode the paver face; too little and the embedded growth doesn't release.
Our Approach
We applied a professional-grade cleaning solution formulated for concrete pavers, letting it dwell to break down the organic buildup throughout the joints and across the surface. After the dwell time, we worked systematically with controlled pressure, enough to clear the joints and lift the deep staining, not enough to damage the paver face.
The result: The pavers went from dark green and heavily stained to clean, showing their natural aggregate color again. The joints were cleared of organic material, improving drainage around the shower drain and dramatically improving the appearance of the space.
Keeping It Clean
For outdoor shower pavers, we recommend cleaning every 1 to 2 seasons, more frequently if the area is heavily shaded. Sealing after cleaning significantly extends the time between cleanings by reducing the porosity of the surface and making it harder for biological growth to establish.
