Block paving cleaning in Welwyn Garden City: what to expect
In Welwyn Garden City, many front gardens have already been paved once, so new paving often starts with breaking out the old surface.
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?
Cleaning washes out some of the jointing sand, so a proper clean is followed by re-sanding with kiln-dried sand once the surface has dried. Many owners then seal the paving to lock the new sand in and keep it cleaner for longer.
- Rinse down of edges, steps and walls
- 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)
- Pre-treatment where needed
