Stonework (Marble, Concrete, Granite & Sandstone)

Our expert conservators can undertake a wide range of outdoor stonework conservation and restoration, including the inpainting, re-gilding and care of existing lettering; cleaning and poultice application, bio-growth removal and prevention, repointing, graffiti removal, and general repairs.

Repairs and fabrication of missing elements to restore the appearance of your outdoor stonework is another possible component of a treatment program, with elements colour-matched for tonal variations to ensure that all repairs are practically invisible to the naked eye.

O’Sullivan Conservation is also equipped to transport and relocate your stone objects.
