Block paving cleaning in Londonderry: what to expect
Londonderry has a big mix of housing, from older terraces near the centre to newer estates further out, so no two drives here start from the same ground.
Dropped kerbs in Northern Ireland go through DfI Roads, so we build that timing into the plan for new drives.

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.
- Weeds and moss removed from the joints
- Rotary surface clean at a pressure that will not blow out the joints
- Rinse down of edges, steps and walls
- Optional biocide and sealer
- Pre-treatment where needed
How we find the cause
- Moss, algae, weeds and oil staining

Cleaning in Londonderry: questions
How often should block paving in Londonderry 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.
