What's included
Full pressure wash of the patio area, working the pressure level to suit concrete or porcelain slabs so nothing gets damaged in the process.
Add-ons worth knowing about
If moss keeps coming back between the joints, a biocide/moss pre-treatment (£20-£50 flat) kills the spores rather than just blasting the visible growth.
Typical cost
A compact town patio (15-25m²) usually comes to £80-£150. A standard family patio (30-50m²) is typically £150-£300.
