The Wind and the Grit
Out here on the plains, there is nothing to block the wind. It picks up grit from the fields and scours the cemeteries day in and day out. That constant friction wears down the stone faces.
We see old marble markers that are nearly bald. The lettering is just a faint shadow. If you hit that with a pressure washer, you lose the name forever. We treat wind-worn stone gently. We clean the dirt out of the grooves so you can read the name again. Then we seal the surface. It helps the stone fight back against that constant sandblasting.
Lichen on Milbank Granite
You see Milbank granite everywhere—it's that deep mahogany stone from up north. It is incredibly hard stuff. But most of the older monuments have "rock pitch" edges—that rough, natural look.
Lichen loves those rough edges. It digs its roots into the uneven surface and covers the stone in gray and orange crust. You can't scrape it off without chipping the rock. We use a biological cleaner that kills the lichen. It takes a few days to work. The lichen dries up, releases its grip, and then we wash it away. The granite looks brand new underneath.
Sioux Quartzite Restoration
In the eastern part of the state, you see a lot of Sioux Quartzite. It is that distinctive pink stone. It is harder than granite, but it has a weakness. It tends to grow a very stubborn black algae in the pores.
Because the stone is so hard, people think they can blast it clean. That is a mistake. The algae is deep in the rock. We use a slow-acting biocide for our headstone cleaning services. It soaks deep into the quartzite and lifts the black staining out from the inside. It brings that pink color back without damaging the stone's natural face.
Bison and Cattle Damage
In the Black Hills and rural ranch plots, fences don't always keep the animals out. A loose cow or a bison bull likes to use headstones as scratching posts. They push hard.
We find heavy monuments tipped over or twisted on their bases. We check for chips and structural cracks. When we do tombstone repair and restoration here, we don't just set the stone back up. We reinforce the base. We lock that tablet down tight. If a bull bison decides to scratch his itch on it, that stone shouldn't budge.
Pine Sap in the Hills
The Black Hills are full of Ponderosa pine. They drop sap all summer long. The sun hits that sap and bakes it into a hard amber glaze on the monuments.
It doesn't scrape off. If you try, you scratch the polish. We use a solvent poultice. We pack it onto the sticky spots. The poultice turns that hard resin into goo, and we wipe it clean. We also get those needles out of there. If they pile up, they act like an acid sponge eating away at the base.
Clay Soil Heaving
Gumbo clay in the river valleys is brutal on foundations. It acts like hydraulic fluid. It absorbs rain and pushes the ground up, then dries out and pulls away. The ground never stops shifting.
That movement snaps concrete footers. We fix a lot of leaning stones by digging out the bad foundation. We replace that shifting clay with a deep pocket of gravel. This gives the stone a stable place to sit that drains water away. If the ground under the footer stays dry, the frost won't heave it out of level.
Farm Dust Buildup
Agriculture is everything here. But during harvest, the air is thick with dust. That dirt settles on the markers and mixes with rain. It creates a mud paste that dries like cement.
It fills in the lettering and dulls the polish. Over years, it creates a layer of grime that hides the stone's color. We use gentle, non-ionic soaps to lift that agricultural film. We flush the letters clean with water and soft picks. As part of our grave site cleaning services, we get that caked-on mud off so the stone shines again.
Irrigation Deposits
In the summer, cemeteries water the grass to keep it green. Our well water is hard. It sprays the stones and leaves heavy white calcium lines across the names.
It bonds tight to the granite. A brush won't touch it. We use a professional wash for cleaning stone gravestones that dissolves the calcium chemically. We rinse it thoroughly, and the inscription becomes clear again.
