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.
Flat ground across much of the East means falls have to be built in carefully so water does not sit on the drive.
- Rotary surface clean at a pressure that will not blow out the joints
- Pre-treatment where needed
- Kiln-dried sand brushed in once dry (re-sanding package)
- Rinse down of edges, steps and walls
- Optional biocide and sealer
How we find the cause
- Which sealer finish suits a slope or patio
- Walls, doors and planting to protect
- Shade and drainage, which affect regrowth
- Moss, algae, weeds and oil staining
- Whether any blocks are loose or sunken first

Not when it is done with a rotary cleaner at medium pressure and the joints are re-sanded afterwards. High-pressure lances held close are what cause damage.
