07725 314415Gravestone & Monument Cleaning across Devon
Headstones, memorials and stone statues weather and stain over the years — lichen, algae and black biological crust gradually obscure the inscription. We clean them gently and safely using the DOFF superheated-steam system and non-hazardous biocide, bringing back the lettering and finish without harsh chemicals or pressure that could damage delicate or historic stone.
The Moore & Franks approach
Memorial cleaning is delicate work and we treat it that way. The DOFF system cleans with low-pressure steam at high temperature — gentle on aged and porous stone, but effective at lifting decades of biological growth. Where a longer-lasting result is wanted we follow up with D/2 Biological Solution, a non-hazardous, conservation-grade product trusted on monuments and statues worldwide.
Whether it's a single family headstone or a larger memorial, we work carefully and respectfully and send you before/after photos so you can see the difference.
A clear, repeatable process.
No surprises, no upsells. The same method every job — that's how you get the same result every time.

Yes. The DOFF system uses temperature rather than pressure — around a tenth of a domestic pressure washer at the nozzle — so it's gentle on aged, porous and historic stone. We use only non-hazardous, conservation-grade products.
