What Professional D/2 Treatment Actually Costs
headstone cleaning in Florida | headstone cleaning in Pennsylvania
I remember my first D/2 job like it was yesterday. Back in 2008, a lady in Charleston called me about her grandfather's marble headstone — covered in black lichen and green algae, looked like it hadn't been cleaned since the 1970s. She asked me what I'd charge, and I quoted her $250. Took me three hours, used almost a full gallon of D/2, and I had to scrub every little carved letter by hand with a soft nylon brush. When I was done, the stone looked almost new — the marble was bright white again, and you could read the inscription from twenty feet away. She cried. I charged too little. But that job taught me what this work is really worth.
Now, after two decades in monument restoration, I get calls and emails every week asking about the cost of professional D2 treatment. People see the price of a bottle at the store — maybe $30 to $40 for a quart — and they think hiring a pro should be cheap. But it's not that simple. Professional work involves more than just spraying and rinsing. It's about knowing the stone, the growth, the wheather, and the right technique. In this post, I'll break down exactly what you're paying for when you hire someone like me, and give you real numbers so you can budget smart.
Let's get into it.
The Base Price Range: What Most Pros Charge
Around here, most experienced stonemasons charge between $200 and $600 for a single headstone. That's a wide range, I know. But it depends on the size of the stone, how dirty it is, and how much detail work is needed. A small flat marker — say 24 by 12 inches — with just a little moss on it might run you $200. A big upright monument with carved lettering, intricate designs, and heavy biological growth? You're looking at $500 to $600 easy. I've done some that took two days and cost $800. The cost of professional D2 treatment isn't just the product — it's the labor, the skill, and the time.
What's Included in That Price?
When I quote a job, it's not just 'spray D/2 and walk away.' Here's what that price covers: First, an inspection of the stone's condition. I check for cracks, loose pieces, or old repairs that might fail. Then I prep the area — cover any nearby plants or grass because D/2 is safe but I'm careful. I apply the D/2 solution with a pump sprayer, let it sit for 10 to 15 minutes (longer if the growth is thick), then scrub with a soft nylon brush — never wire, never anything harsh. Rinse with clean water from a garden hose, no pressure washer. Sometimes I need a second application. I also clean the base and any stone border around the plot. And I take photos before and after for the family. That's a full treatment. Some guys just spray and rinse — but that's not the same quality.
Why the Product Cost Isn't the Main Expense
A gallon of D/2 costs about $80 to $100 retail. A pro can buy it in bulk for less, maybe $60 to $70 a gallon. But that's not what you're paying for. You're paying for my time, my truck, my insurance, my brushes, my sprayer, and my knowledge. I've seen guys ruin a limestone marker by using a pressure washer — blasted the surface right off. I've seen others use harsh household cleaners that left white stains and ate away the polish. That's not me. I've been doing this for 20 years. I know that marble is soft, that sandstone crumbles, that granite can take more but still needs care. That expertise is worth something. A one-time treatment done right can last 5 to 10 years, depending on the climate. So spread that $400 over a decade — it's $40 a year. Not bad for keeping a loved one's stone looking respectful.
Factors That Drive the Price Up or Down
Location matters. If your cemetary is an hour drive from me, I'm charging travel time — usually $50 to $100 extra. If the stone is in a shaded, damp spot with heavy lichen and moss, expect to pay more because it takes longer. Some stones have deep carved letters that need careful scrubbing with a small brush — that's tedious work. Weather plays a role too. I don't treat stones in direct sun or when it's below 50 degrees — D/2 works best in mild, overcast conditions. So if I of to reschedule, that's built into my pricing. Also, if the stone has been previously sealed with something like wax or silicone, I have to strip that first. That's an extra charge, maybe $100 to $200. Bottom line: the cleaner the stone, the easier the job, the lower the price.
DIY vs. Pro: When to Spend the Money
Look, I'm not going to tell you never to do it yourself. If you've got a simple granite marker and some patience, you can buy a quart of D/2 for $30, follow the instructions, and do a decent job. But if the stone is marble or limestone, if it's old and fragile, if it has intricate carvings, or if you just don't have the time — hire a pro. I've seen too many DIY attempts go wrong. One guy used a wire brush on sandstone and gouged grooves into it. Another mixed D/2 with bleach thinking it would work faster — ruined the stone's color. The cost of professional D2 treatment might feel like alot upfront, but it's cheap compared to the cost of repairs. I've fixed stones that were damaged by bad cleaning, and that's not cheap — $1,000 or more. So ask yourself: is this a stone you want to risk? For me, I'd rather pay a pro for reassurance.
Frequently Asked Questions
Q: Does the cost of professional D2 treatment include the D/2 solution itself?
A: Yes, most pros include the D/2 solution in their price. We buy it in bulk and apply it as part of the service. You don't need to supply anything. Just make sure to ask when getting a quote — some less honest folks might charge extra for the product.
Q: Why do some quotes for headstone cleaning vary so much between companies?
A: Experience and insurance are the big factors. A guy with a truck and a sprayer might charge $150, but he might not know how to handle old marble or sandstone. A licensed stonemason with 20 years in the business and liability insurance will charge more — but you're paying for safety and quality. I've seen too many cheap jobs that caused damage. You get what you pay for.
Q: Is there a warranty or guarantee on professional D/2 treatment?
A: I offer a one-year warranty on my work. If the stone gets significantly dirty again within a year due to normal conditions, I'll retreat it for free. But if someone sprays it with something harsh or pressure-washes it after I leave, that voids it. Most reputable pros offer something similiar — always ask before hiring.
Q: Can I get a discount if I have multiple family stones cleaned at once?
A: Absolutely. If you've got three or four stones in the same cemetery, I usually knock 10 to 20 percent off the total. It saves me travel time and setup. I've done whole family plots for $1,200 — that's about $300 per stone. Just ask. Most pros will work with you if you're flexible on timing.
Q: Does the cost include cleaning the stone base and any surrounding concrete?
A: It should, but not all pros do. I always clean the base and any stone borders as part of the treatment. Some guys only do the headstone itself. When you're getting quotes, be specific: ask if the base is included. If not, expect an extra $50 to $100 for that work.
