What does a block paving cleaning job involve?
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.
Hilly streets in much of Wales mean many drives slope, which shapes the falls, the edging and the water route.
- Pre-treatment where needed
- Optional biocide and sealer
- Kiln-dried sand brushed in once dry (re-sanding package)
- Rinse down of edges, steps and walls
- Weeds and moss removed from the joints
How we find the cause
- Whether any blocks are loose or sunken first
- Whether the paving is permeable (no sand, no sealing with the wrong product)
- Which sealer finish suits a slope or patio
- Type of block and its age
- Walls, doors and planting to protect

Cleaning in Gwynedd: questions
How often should block paving in Gwynedd be cleaned?
Every two to four years for most drives, more often for shaded or north-facing paving.
Will cleaning damage my block paving?
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.
Can you seal my drive straight after cleaning?
Only once it is completely dry and re-sanded. Sealing damp paving traps moisture and can leave a white bloom.
