Headstone Cleaning & Restoration Services in Madison, WI

Cleaning Hard Water Scale and Algae in Madison

Madison sits right between the lakes, so the air feels heavy and damp. That is exactly what algae needs to grow. At Forest Hill and Resurrection, the headstones on the shady side turn green fast. It makes the family plot look forgotten, and that wet moss keeps the stone soggy, which leads to cracks.

The water here is another headache. It is full of minerals. When the sprinklers hit the stones in July, the water evaporates, but the white calcium stays. It bakes a hard crust onto the granite that hides the names. Families searching for headstone cleaning services near me call us to melt that white scale off or to clean up the green growth taking over the stone.

Hard Water Calcium Deposits

Madison water is brutal. It ruins your faucets at home, and it does the same thing to headstones. When the sprinklers hit a hot monument, the minerals bake onto the surface immediately. A wire brush won't even scratch it.

We use a strong acid to eat the calcium, but it is a race against time. The acid melts the white crust, but if you look away for a minute, it will start eating the polish on the stone. We rinse it the second the reaction finishes to keep the granite safe.

Green Algae and Moss

The humidity from the lakes feeds the algae. It starts as a light green dust and turns into a thick mat if you ignore it. It grows right into the pores of the stone.

We don't use pressure washers. Shooting water into the stone just causes damage later. We spray a cleaner that kills the growth. Once it turns brown and dies, it lets go of the rock. Then we can just brush it away. It’s gentle and it works.

The Freeze-Thaw Shuffle

It isn't the deep cold that hurts the stones; it’s the constant change. The ground goes from rock-hard ice to soft mud and back again. That instability pushes the markers around. That is why stones that were straight in December look like they are tipping over come April.

We fix this by digging out that shifting dirt. We fill the hole with crushed rock instead of dirt. Rock drains well. If there is no water to freeze underneath, the stone stops moving.

Tree Sap and Pollen

Forest Hill is full of big trees. They look great, but they create a mess. In the spring, wet pollen pastes everything yellow. In the summer, the pines drop sap that cooks onto the stone like tar.

You can't scrape that sap off without scratching the granite. We soak the spot with a solvent until the tar gets gooey again. Then we just wipe it up. It takes a lot of rags, but it saves the finish.

Service Costs in Madison

Removing heavy mineral scale is expensive because the chemicals are pricey. Resetting a large monument in the spring takes a crew. I need to see the job to give you a fair price. We have an online tool for this. You choose the cemetery, tell us what is wrong, and you get the cost right there.
