Block paving cleaning in Penarth: the local picture
Around Penarth, plots are often larger and drives longer, so edging, falls and the route the water takes need planning.
Wales is wetter than most of England, and new front paving has to be permeable or drain within the property, so drainage is designed in from the start.

What is included?
Block paving cleaning removes moss, algae, weeds and ground-in dirt from the surface and the joints, usually with a rotary surface cleaner on a pressure washer, which cleans evenly without the stripes a hand lance leaves. A biocide treatment can be applied to slow regrowth.
- Rinse down of edges, steps and walls
- Rotary surface clean at a pressure that will not blow out the joints
- Optional biocide and sealer
- Weeds and moss removed from the joints
- Kiln-dried sand brushed in once dry (re-sanding package)
