Inland Humidity & Cyanobacteria
Miramar sits on the wetland edge. The air stays thick and wet. Granite headstones act like hard sponges here. They soak up moisture and hold it inside the pores. The stone stays damp internally. This triggers rapid growth of Gloeocapsa magma (black algae).
You see a dark, oily stain covering the dates. It isn't dirt. It is a living colony rooting into the stone.
Searching for headstone cleaning services near me often leads to bleach. Do not use it. Bleach only whitens the surface. The roots survive inside the stone and grow back fast. We use specialized grave site cleaning services. We use a biological soaking agent. It soaks into the rock. It kills the algae cells deep inside. The stone stays clean because the infestation is dead.
Peat Soil Subsidence
The ground here is reclaimed swamp. It is full of organic peat and "muck." This soil is soft. Heavy granite bases compress this ground. They push the water right out of the muck. The soil collapses under the load.
The monument tips or sinks. Grass grows over the base. Adding topsoil fails; the stone just pushes the new dirt down. For proper tombstone repair and restoration, we change the support system. We dig out the soft muck. We install a pad of angular, crushed stone. These rocks lock together. They create a friction pile that supports the weight, even in soft organic soil.
Irrigation Rust Stains
Cemeteries irrigate constantly. Local wells pump water loaded with iron and sulfur. On a hot afternoon, sprinkler water hits the stone and flashes to steam. The water leaves, but the iron stays.
It bonds to the granite surface. You get ugly orange or red streaks. Scrubbing scratches the polish. We use specific cleaning stone gravestones chemistry. We apply a clay paste with a chelating agent. It acts like a magnet. It pulls iron particles out of the pores and traps them. We rinse the paste away, leaving the stone clear.
Bronze Heat Damage
Miramar sun is intense. Bronze markers bake. The factory clear coat expands until it cracks. Humidity gets trapped under that broken seal. It attacks the raw copper, turning it green.
We use strict cleaning bronze cemetery markers protocols. We strip the failed coating. We chemically remove the corrosion. Then we heat the metal and apply a new marine-grade lacquer. This seals the marker against the heat.
