Block paving cleaning in Potters Bar: the local picture
Around Potters Bar, plots are often larger and drives longer, so edging, falls and the route the water takes need planning.
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
- Pre-treatment where needed
- Weeds and moss removed from the joints
- Optional biocide and sealer
- Rotary surface clean at a pressure that will not blow out the joints

Cleaning in Potters Bar: questions
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.
Do you cover Borehamwood, Hatfield and Cheshunt?
Yes. We cover Potters Bar and the places around it, including Borehamwood, Hatfield and Cheshunt, and the rest of Hertfordshire.
How often should block paving in Potters Bar be cleaned?
Every two to four years for most drives, more often for shaded or north-facing paving.
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.
