Planning a block paving cleaning job in Letchworth Garden City
In Letchworth Garden City, many front gardens have already been paved once, so new paving often starts with breaking out the old surface.
Clay soils are common in parts of the East of England, so drainage and sub-base depth get extra attention.

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
- Pre-treatment where needed
- Kiln-dried sand brushed in once dry (re-sanding package)
- Rinse down of edges, steps and walls
- Optional biocide and sealer

Cleaning in Letchworth Garden City: 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.
How often should block paving in Letchworth Garden City be cleaned?
Every two to four years for most drives, more often for shaded or north-facing paving.
Do you cover Hitchin, Stevenage and Welwyn Garden City?
Yes. We cover Letchworth Garden City and the places around it, including Hitchin, Stevenage and Welwyn Garden City, and the rest of Hertfordshire.
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.
