Exposed aggregate driveway clean, St Helens
An exposed aggregate concrete driveway darkened with dirt and algae. Cleaned back so the stones in the surface show through again.

Concrete driveways, flagged drives, concrete patio slabs and paths cleaned with a rotary surface cleaner and treated to slow moss and algae coming back. Minimum charge £150.

This page covers concrete patios and paths as well as driveways. If you have stone flags rather than concrete, see Indian sandstone or patio cleaning.
