Winter Splits Granite
Iowa winters are brutal on stone. The cold isn't the worst part. It’s the constant up and down. A sunny afternoon melts the snow, and water seeps into the granite. By midnight, it’s frozen solid again.
Ice expands and acts like a wedge driving the stone apart. We see bases split right down the middle in spring. Ignore it, and the monument falls apart. When we do tombstone repair and restoration, we scrape out the loose grit inside the break. Then we inject a structural stone epoxy. It bonds the pieces back together solid and seals the gap against the next freeze.
Harvest Dust and Grime
You know how thick the air gets during harvest. Combines kick up massive clouds of dirt and chaff. That dust settles on every headstone in the county.
Add a little rain to that dust, and you get instant mud. The sun bakes it right onto the granite. It forms a hard crust that covers up the names. Wiping it dry just grinds the grit into the polish. We use gentle cleaners designed for our headstone cleaning services to lift that layer. We float the grime off without scratching the finish, letting the stone shine again.
Sinking in Black Dirt
Iowa has incredible soil, but that rich black dirt is soft. Heavy monuments don't float on top of it; they settle. We constantly find markers sunk so low the dates are underground.
Shoveling dirt on top fixes nothing. The weight just pushes it down again. We have to dig the whole thing out. We replace that soft topsoil with a packed base of crushed rock. This gives the monument a solid footer. It keeps the marker sitting high and level, even when the ground turns to mush during the thaw.
Soft Limestone Wears Down
Walk into any pioneer cemetery here, and it is full of limestone. It is a soft rock. Give it a century of wind and storms, and the face of the rock just wears down. The names fade away.
You have to go easy on these. A pressure washer will blast the surface right off. We stick to soft brushes and a specialized cleaner that soaks deep into the pores. It kills the mold eating the stone. We can't bring the lost rock back, but stripping that grime stops the decay and lets you read the inscription again.
Mowers and Grass Stains
Out in the rural plots, grass shoots up fast. Mowing crews rush to keep up. They often spray wet grass clippings right against the headstones.
That wet grass rots fast. It stains the stone green and brown, and rain won't wash it off. It makes the grave look abandoned. As part of our cemetery clean up, we scrub those organic stains out. We use a solution that pulls the discoloration right out of the rock pores. We also hand-trim around the base to keep the mowers at a safe distance.
Storm Cleanup and Sap
Wind brings branches down, and trees drip sap all summer. That sap lands on the marker and cooks into a hard, black resin.
It sticks like glue. If you take a blade to it, you scratch the stone. We use a poultice paste for cleaning stone gravestones. We pack it on the sap spots, and it melts the resin chemically. Then we just wipe it away. We also clear out the sticks and leaves trapping moisture against the base, because that is where moss starts.
River Silt
Flooding happens near the rivers. Once the water recedes, it leaves behind a gray coating of heavy silt.
That mud packs tight into the lettering. Sun hits it, and it turns to concrete. Brushing doesn't touch it. We use low-pressure water and plastic picks to dig that mud out of the engravings until the letters are sharp again. We make sure the name is visible after the waters go down.
