Block paving cleaning in Harpenden: the local picture
Harpenden is a sizeable town with a mix of semis, terraces and newer estates, and many drives here were first laid decades ago.
Flat ground across much of the East means falls have to be built in carefully so water does not sit on the drive.

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
- Weeds and moss removed from the joints
- Rotary surface clean at a pressure that will not blow out the joints
- Kiln-dried sand brushed in once dry (re-sanding package)
- Pre-treatment where needed
How we find the cause
- How much joint sand is left
- Which sealer finish suits a slope or patio
- Walls, doors and planting to protect
- Type of block and its age
- Shade and drainage, which affect regrowth

Cleaning in Harpenden: questions
How much does a block paving cleaning job cost in Harpenden?
Guide price for Harpenden: £2.50–£5.50 per m² including VAT, with a minimum charge for small areas.
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.
How often should block paving in Harpenden 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.
