Indian sandstone, carefully restored
Specialist cleaning for suitable Indian sandstone patios and paths, including assessment of persistent black spot and joint condition.
Natural stone needs informed care
Clean sandstone without treating it like concrete
Indian sandstone has natural variation, porous faces and joints that deserve a considered approach. We inspect the stone, pointing and staining before proposing a treatment.
Black spot is a persistent biological growth. Improvement can require specialist treatment and realistic expectations; results vary with the age and condition of the paving.

Cleaning planned around the stone
Surface identification
We first check the material and condition so the method is suitable for natural stone.
Targeted treatment
Where appropriate, persistent organic marking can be treated as part of a controlled cleaning process.
Joint review
Loose, failed or missing pointing is identified before cleaning and can be quoted separately if restoration is required.
Before
Weathering can hide the colour beneath
Shaded paths and patios often accumulate dirt and organic growth gradually. The right preparation and dwell time can be as important as the cleaning equipment itself.
After
A refreshed natural finish
Our aim is to reveal a cleaner, more even-looking surface while respecting the character and variation of the stone. We explain any marks or historic damage likely to remain.
