"Stone cleaning is stone cleaning. Anyone can do it."
This is one of the most damaging myths in our industry.
The wrong method on sandstone, the stone that built the majority of Scotland's finest homes, can cause irreversible damage. Erosion of the surface layer. Increased moisture pe*******on. Accelerated decay of the mortar joints.
And the worst part? The damage rarely shows immediately. It shows three, five, ten years later, when it's expensive and complicated to fix.
DOFF cleaning exists precisely because stone is not all the same. Sandstone is soft. Limestone is reactive. Granite is hard but still needs the right approach.
We assess the stone before we ever touch it. We choose the method based on what we find. And we use the DOFF system because it's the safest effective cleaning technology available.
Your stone is worth getting right.
