Great South Bay Salt Aerosol
Amityville sits right on the Great South Bay. The air is heavy with salt spray. That saltwater soaks deep into the granite.
The water dries, but the salt stays trapped inside. As the salt hardens and grows, it pushes outward. It cracks the stone from the inside. Searching for headstone cleaning services near me often suggests pressure washing. That is a mistake. It drives salt deeper. We use desalination poultices. These clay packs pull the salt out like a magnet. We flush it away with distilled water.
Glacial Outwash Instability
The ground here is loose sand left over from glaciers. The water table is high. There is no solid earth to hold the weight.
Vibration from Route 27 traffic shakes the ground and turns the wet sand into liquid. Monuments sink straight down or tilt to the side. Adding topsoil is useless; it just adds dead weight to a soft base. For permanent tombstone repair and restoration, we stabilize the sub-grade. We dig out the loose sand and install angular gravel friction piles. This locks the foundation in place.
Route 110 & LIRR Metallic Fallout
Traffic on Broadway (Route 110) and the LIRR kicks up metallic dust. Iron particles settle on the stone. When it rains, they rust.
The result is deep orange staining. It bonds chemically to the stone itself. It is inorganic. Biocides fail here. We use specialized grave site cleaning services. Ammonium thioglycolate turns solid rust into a liquid. We extract it chemically without scrubbing.
Coastal Biological Growth
The damp air from the bay feeds mold and algae. Their roots dig deep into the stone.
They secrete acid that eats the polish. Scrapers just scratch the surface. We use specialized cleaners for cleaning stone gravestones. These fluids penetrate the stone and kill the algae at the root structure. The residue stops it from growing back.
Storm Surge Efflorescence
Storm surges flood the grounds with saltwater. The base of the monuments soaks it up. When it dries, a white line appears.
This is a mineral scale that bonds to the granite. Acid cleaners burn the stone. We use neutral chelating agents. They lift the minerals into a liquid solution. We rinse the scale away safely.
