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.
Dropped kerbs in Northern Ireland go through DfI Roads, so we build that timing into the plan for new drives.
- Rinse down of edges, steps and walls
- Pre-treatment where needed
- Rotary surface clean at a pressure that will not blow out the joints
- Optional biocide and sealer
- Kiln-dried sand brushed in once dry (re-sanding package)
How we find the cause
- Shade and drainage, which affect regrowth
- Walls, doors and planting to protect
- Which sealer finish suits a slope or patio
- How much joint sand is left
- Moss, algae, weeds and oil staining

Cleaning in County Londonderry: questions
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.
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.
