What you get with our cleaning service

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.

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

What we look at first in Watford

  • Moss, algae, weeds and oil staining
  • Whether the paving is permeable (no sand, no sealing with the wrong product)
  • Shade and drainage, which affect regrowth
  • Whether any blocks are loose or sunken first
  • Which sealer finish suits a slope or patio

Cleaning in Watford: questions

How often should block paving in Watford 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.

Do you cover Bushey, North Watford and Rickmansworth?

Yes. We cover Watford and the places around it, including Bushey, North Watford and Rickmansworth, 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.
