Top Gravestone Conservators in the Ohio River Valley (Cincinnati, Louisville & Beyond)

headstone cleaning in Ohio | headstone cleaning in Cincinnati Ohio

I’ll never forget the first time I saw a headstone that someone had tried to clean with bleach. It was in a small cemetary just outside of Louisville, back in 2017. The stone was a beautifull, dove-gray marble from the 1880s — a little girl’s marker. The family had meant well. They’d scrubbed it with a stiff brush and bleach, hoping to make it look new again. Instead, they’d turned the surface into a rough, chalky mess. The lettering was still readable, barely, but the stone’s original polish was gone forever. I sat down on the grass next to it and just felt sick. That’s the day I decided to stop just doing cleanings and start helping people find real conservators — people who understand that old stone isn’t a kitchen counter.

I’ve been a funeral celebrant for over twenty years now, and part of my job is helping families restore their loved ones’ memorials. The Ohio River Valley is full of historic cemeteries — places like Spring Grove in Cincinnati, Cave Hill in Louisville, and hundreds of small churchyards in between. The problem is, finding someone who actually knows what they’re doing can be a nightmare. You call a guy who says he does headstone cleaning, and he shows up with a pressure washer and a bottle of muriatic acid. I’ve seen it happen. More times than I can count. That’s why I put this list together — so you don’t have to learn the hard way.

Here are the best gravestone conservators in the Ohio River Valley, the ones I trust with my own family’s stones, and the ones who won’t ruin your grandmother’s marker.

What Makes a Good Gravestone Conservator?

Before I give you names, let me tell you what to look for. A real conservator — not just a cleaner — will start with an assessment. They’ll look at the stone’s material (marble, granite, sandstone, limestone, slate) and it's condition. Is it flaking? Is it cracked? Is there biological growth (lichen, moss, algae)? They’ll ask about the cemetery’s rules — some places have strict guidelines about what chemicals you can use. Then they’ll tell you their plan. They should use only pH-neutral, non-ionic cleaners, like D/2 Biological Solution. That stuff is magic — it kills the organic growth without eating the stone. They should work with soft brushes (natural bristle, not wire). They should never pressure wash. Never. And they should never use harsh household chemicals. If they show up with a spray bottle of anything that smells like a swimming pool, send them home. Big mistake. I’ve seen stones that looked like they’d been sandblasted after one bleach treatment. It’s permanent damage.

Cincinnati: The Best in the Queen City

Spring Grove Cemetery is one of the most beautiful burial grounds in the country, and it’s got its own team of in-house conservators. But if you’re working with a private family plot or a smaller cemetery, I’ve got two names for you. First is Mark Templeton at Legacy Stone Care. He’s been doing this for over fifteen years. He’s meticulous — I watched him spend two hours on a single small marble footstone, just gently lifting lichen with a wooden scraper. He uses D/2 exclusively, and he’s trained in stone consolidation (that’s when you stabilize crumbling stone with a special lime-based mortar). He works all over the metro area, from Covington to Mason. Second is Sarah O’Neill at River Valley Monument. She’s a third-generation stone carver who moved into restoration about ten years ago. She’s the person I call when a stone has a crack that needs pinning, or when a base is sinking. She doesn’t do quick fixes. She’ll dig out the old concrete base and repour it properly. Took her three days on a big monument in Avondale last year. Worth it.

Louisville: The Real Deal South of the River

Cave Hill Cemetery is the crown jewel of Louisville, and they have a list of approved conservators. I’ve worked with two of them personally. First is Tom Grady at Stone Solutions Kentucky. Tom is a former geologist, which means he actually understands the chemistry of stone. He won’t touch a stone without testing the pH of the biological growth first. Sounds crazy, right? But it matters — different mosses need different treatment. He’s also the only person I know who uses a steam cleaning system (low pressure, just steam) for delicate sandstone markers. It’s slow. Very slow. But it gets the job done without damage. The other person I trust is Janelle Cooper at Cooper Monuments. She’s a small operation — just her and one assistant — but she’s been restoring stones in the Ohio River Valley for twenty-three years. She’s the one you want for a badly deteriorated limestone marker. She’ll do a poultice treatment to draw out deep stains, then apply a breathable sealer. She told me once, ‘I don’t make them look new. I make them look old again, but clean.’ That’s the right attitude.

Beyond the Big Cities: Small Towns, Big Hearts

Don’t overlook the smaller guys. In Madison, Indiana, there’s a man named Earl Whitaker who runs Whitaker Stoneworks. He’s not on Google Maps — you have to call the local historical society to get his number. But he’s been caring for the gravestones in that area for forty years. He does it the old way: hand tools, patience, and alot of respect. I saw him fix a broken slate stone from 1820 with nothing but a brass pin and epoxy. It looked smooth. In Maysville, Kentucky, there’s a woman named Ruth Ann Carter who works out of her garage. She’s a retired art conservator who now does gravestones for free — she only charges for materials. She’s saved dozens of stones in the Washington Baptist Church cemetery. Her trick? She uses a mix of distilled water and a tiny amount of pH-neutral dish soap for the first pass, then finishes with D/2. Simple. Effective. And she’ll talk your ear off about 19th-century carving techniques. I love her. If you’re in the smaller towns along the river, ask around at the local historical society or the county clerk’s office. The best conservators often don’t have websites. They have word of mouth.

What to Ask Before You Hire Anyone

I’ve made the mistake of assuming someone knew what they were doing. Never again. Here’s my short list of questions. First: ‘What chemicals do you use?’ If they don’t say D/2 Biological Solution or another pH-neutral, non-ionic cleaner, run. Second: ‘Do you use a pressure washer?’ The answer should be no. If they say ‘only on low,’ that’s still a risk. I’ve seen low-pressure washers pit sandstone. Third: ‘How do you handle biological growth?’ They should say they use a soft brush and a gentle cleaner, not bleach or acid. Fourth: ‘Can you show me before-and-after photos of similiar stones?’ A real conservator will have a portfolio. And fifth: ‘Are you insured?’ This is a big one. If they damage a stone, you need to know they can make it right. I learned that one the hard way when a guy dropped a 200-pound granite urn and cracked it. He just walked away. Never again.

Frequently Asked Questions

Q: How do I find a conservator in a small town along the Ohio River Valley?

A: Start with the local historical society. They almost always have a list of people who work on old cemeteries. County clerks’ offices sometimes know, too. I’ve also had luck asking at monument companies that sell new stones — they often know who does restoration work on the side. And don’t be afraid to call a conservator in a bigger city like Cincinnati or Louisville and ask if they know anyone in your area. They usually do.

Q: Is D/2 Biological Solution safe for all types of stone?

A: Yes, it’s safe for marble, granite, limestone, sandstone, slate, and even bronze. It’s a non-ionic, pH-neutral cleaner that kills biological growth (lichen, moss, algae) without damaging the stone or the environment. I’ve used it on a hundred-year-old marble angel in Spring Grove and on a rough sandstone slab in a churchyard in Carrollton. Worked perfectly on both. Just follow the instructions — spray it on, let it sit, then gently rinse with low-pressure water.

Q: What’s the difference between a gravestone cleaner and a conservator?

A: A cleaner is someone who washes stones. A conservator is someone who understands the material and the history. A conservator will assess the stone’s condition, stabilize cracks, consolidate crumbling edges, and use only safe methods. A cleaner might just pressure wash and move on. For a family heirloom, you want a conservator. For a modern granite marker that just has dirt on it, a cleaner might be fine — but ask them what they use first.

Q: Can a badly damaged marble headstone be restored?

A: Sometimes, but it depends on the damage. A conservator can pin cracked pieces back together with brass or stainless steel pins and epoxy. They can fill small chips with a lime-based mortar. But if the stone is deeply pitted from acid or bleach, that damage is permanent. The surface can be cleaned and stabilized, but the polish is gone. That’s why it’s so important to avoid harsh chemicals in the first place.

Q: How much does professional gravestone conservation cost in the Ohio River Valley?

A: It varies wildly. A simple cleaning with D/2 on a small granite marker might cost $100 to $200. A full conservation on a large, damaged marble monument can run $1,000 to $3,000 or more, especially if it involves structural repairs. I’ve paid $500 just for a single day of work on a complex limestone piece. Always get a written estimate. And remember — cheap is usually bad. You’re paying for someone’s knowledge and care.
