Grave Cleaning & Headstone Restoration in Pierre

Stabilizing Stones in Gumbo Clay and Cleaning Bluff Dust in Pierre

Pierre sits high on the river bluffs. Wind hits the cemeteries hard here. At Riverside and Calvary, that wind drives grit and dust into the face of every headstone. It packs the names and dates full of dirt. Rain turns that dirt to mud, and the dry prairie air hardens it. The lettering ends up flush with the stone, making the inscription look like a flat grey smear.

The ground is the bigger problem. Pierre is built on gumbo clay. Wet clay expands. Dry clay cracks. That movement pushes stones all over the place. This soil wrecks foundations. We see upright monuments tipping over and flat markers that have been heaved up and thrown out of level. Families searching for headstone cleaning services near me use our app to book a leveling service for these shifting stones or to get that impacted bluff dirt cleaned out.

Dealing with Expansive Gumbo Clay

Gumbo clay is nasty stuff to build on. It holds water and pushes with a lot of force. We see heavy stones lifted inches above the grass in the spring. Then July hits, the ground cracks open, and the stone tips over because there is nothing holding it up.

Shoving dirt under a tipping stone is a waste of time. We have to dig the whole foundation out. We remove the clay and replace it with a deep pad of angular gravel. Gravel locks together and lets the water run through. This pad stays solid and flat, even when the clay around it swells and shrinks.

Impacted Windblown Dirt

The wind on these bluffs forces fine dirt into the rough cuts of the engraving. Over time, that dust builds up inside the lettering. It gets wet, dries out, and turns into a hard plug. It fills the letters completely. You lose the contrast between the polished face and the rough engraving.

We don't use pressure washers. They can chip the edges of the letters. We clean this by hand. We use wooden tools to pick the packed dirt out of every groove. We scrub the remainder with a soft brush. It takes time to do it right, but it brings the name back without damaging the stone.

Lichen on Historic Stones

In the older sections, like at Cedar Hill across the river, we see a lot of lichen on the rough stone. It grows in crusty patches that dig into the rock. It traps moisture against the surface. In winter, that water freezes and pops pieces of the stone off.

Scraping lichen is a bad idea. It takes the stone surface with it. We kill it with a biological cleaner. The plant dies and releases its grip. It turns to dust. We brush the dead material off, leaving the stone clean and intact.

Hard Water Mineral Scale

The irrigation water here leaves a mark. It is full of minerals. When sprinklers hit a hot monument, the water flashes off instantly. The calcium stays behind. It forms a hard white haze that covers the black polish.

We use a specialized cleaner to eat through that mineral crust. We brush it on and watch it fizz. As soon as the scale is dissolved, we rinse it. Acid will dull the polish if it sits. We flood the stone with water to wash all the chemicals away.
