Cleaning River Algae and Iron Rust in Pawtucket
Pawtucket is an old mill town built on the river. That history shapes the problems we see in the cemeteries. The Blackstone River keeps the air damp, which covers the stones in heavy green algae. And the old iron fences in places like Oak Grove are rusting apart, staining the granite underneath.
We also deal with city issues here. Mineral Spring and Riverside cemeteries are right in the thick of town. We see vandalism, spray paint, and stones shifting in the soft, silty river soil. Families searching for headstone cleaning services near me call us to remove these deep rust stains and to safely strip paint from porous stone.
Rust Stains from Iron Fences
Many family plots in Pawtucket are surrounded by antique iron rails. Over a hundred years, that iron corrodes. The rust drips down onto the granite curbing and the base of the headstone. It soaks deep into the rock, leaving an orange streak that looks like a burn mark.
Bleach makes rust worse. It sets the stain. We use a specialized chemical that reacts with iron oxide. It turns the rust purple, then liquid. We rinse it out. It might take three or four applications to get it all, but it pulls the orange color right out of the pores.
Algae and River Dampness
The humidity from the Blackstone River hits the cemeteries every morning. In the shade, the moisture turns into thick green slime and black mold. It gets so bad you can’t even read the names anymore. It’s also dangerous—wet algae is as slippery as ice.
Pressure washing just forces the mold deeper into the pores. We apply the biocide and leave it. The chemical kills the root system. Over the next few weeks, the weather does the rest. The rain rinses the dead matter away, and the original stone color comes back.
Graffiti and Paint Removal
We see a lot of vandalism in the urban plots. The issue with granite is that it’s like a hard sponge. It drinks the paint. If you just grab a rag and thinner, you’ll just smear the paint deeper into the rock and make a huge mess.
We pack the stain in a special paste. We cover it with plastic to keep it wet. The paste pulls the paint out of the stone like a magnet. After a day or two, we peel the paste off, and the paint comes with it.
Tilting Stones in Silty Soil
The ground by the river is basically mud. It’s soft. Huge granite monuments are too heavy for it. As the mud shifts, the stones start to tip over.
Shoving a wedge under the corner is a band-aid. It won't hold. We have to dig the whole foundation out. We replace the mud with crushed stone and pack it down tight. That gives the monument a solid base that won't move when the river rises.
Service Costs in Pawtucket
Rust jobs take time because we have to apply the treatment over and over. Graffiti is the biggest wildcard. Fresh paint is easier to lift, but if that tag has been baking in the sun for five years, it fights us every inch of the way. I don't give quotes over the phone. I have to stand in front of the monument to see how bad the damage is.
