Inland Heat & Sticky Mold
Pine Hills sits inland, away from the coast. We don't get the ocean breeze here. The heat gets trapped. Humidity sits heavy on the ground. Granite absorbs this stagnant moisture. It stays wet deep inside the pores. This creates a perfect incubator for Gloeocapsa magma (black algae).
You see a thick, black skin on the stone. It traps heat. It hides the inscription.
Searching for headstone cleaning services near me often points to bleach. Do not use it. Bleach damages the stone matrix. It leaves the roots alive deeper in the pores. We use specialized grave site cleaning services. We use a biological soaking agent. It penetrates the rock safely. It kills the algae cells chemically. The black crust falls off. The stone stays clean longer.
Sugar Sand Washout
The soil here is loose "sugar sand." It shifts constantly. Heavy afternoon storms turn the ground into liquid mud. Water rushes under the concrete base. It scours the sand away.
The foundation floats on nothing. The monument tilts or sinks. Adding topsoil is a waste; it washes away in the next storm. For lasting tombstone repair and restoration, we stabilize the sub-base. We excavate the loose sand. We install angular gravel. The rocks lock together. They create a friction pile. This supports the weight, even when the ground is wet.
Irrigation Rust (Well Water)
Cemeteries irrigate constantly to fight the heat. The water comes from deep wells rich in iron. Sprinklers hit the hot stone. The water evaporates. The iron bonds to the granite.
It creates heavy orange streaks. Scrubbing scratches the stone face. We use professional cleaning stone gravestones chemistry. We apply a chelating paste. It acts like a magnet. It pulls the iron particles out of the pores. We rinse it away. The stone looks new again.
Pine Sap & Pollen
Many older sections of local cemeteries are shaded by pine trees. Sap drops onto the markers. The sun bakes it into a hard amber resin. Pollen and dust stick to it, forming a concrete-like grime.
Soap won't clean this. We use specific solvents to dissolve the hardened sap chemically. We lift it off without abrasion, preserving the stone's polish.
