Atlantic Salt & Mold
Hollywood sits right in the spray zone. The ocean wind carries salt. Salt acts like a magnet for water. It lands on the granite and pulls humidity right out of the air. It locks that moisture inside the stone pores. The marker never dries out. It stays wet internally. This feeds Gloeocapsa magma (black algae).
The mold loves this salty, wet environment. It grows thick and fast. It looks like tar. It eats the polish.
Searching for headstone cleaning services near me usually leads to pressure washing. Do not do that here. High pressure drives salt crystals deep into the rock. They expand later and crack the stone. We use industrial grave site cleaning services. We apply a chemical poultice. It sucks the salt out of the pores. It kills the mold roots. The stone gets dry and clean without physical damage.
Bronze Disease (Chlorides)
Salt air destroys bronze markers. The wind blasts the factory clear coat with sand. The coating fails. Then chlorides in the air hit the bare copper. It turns green immediately.
This is "bronze disease." It is an active chemical fire eating the metal. It pits the surface and destroys the names. We use strict cleaning bronze cemetery markers steps. We strip the dead coating. We scrub away the green chlorides. Then we heat the metal and seal it with heavy marine lacquer. It creates a shield against the ocean air.
Sugar Sand Washout
The soil here is coastal "sugar sand." It is fine. It flows like water when it rains. Storms rush water under the monument base. The sand washes out.
The base loses support. The headstone tilts or sinks. Dumping topsoil is a waste of money. The rain just washes the sand out again. Proper tombstone repair and restoration needs a friction pile. We dig out the loose sand. We put in jagged, angular gravel. The rocks lock together. They hold the weight even when the ground turns to soup.
Internal Efflorescence
Salt dissolves in the morning dew. It soaks into the rock. The sun comes out and dries the water. The salt stays behind. It turns back into crystals inside the granite.
These crystals grow. They expand. That pressure pops the face off the stone (spalling). We use professional cleaning stone gravestones chemistry to fix this. We use a solution that dissolves those internal salts. We flush them out to the surface before they break the rock face.
