Planning a block paving cleaning job in Cardiff

Across Cardiff, front gardens range from narrow terrace plots to broad modern drives, and the best block, pattern and drainage choice changes with them.

Hilly streets in much of Wales mean many drives slope, which shapes the falls, the edging and the water route.

What does a block paving cleaning job involve?

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
  • Optional biocide and sealer
  • Rotary surface clean at a pressure that will not blow out the joints
  • Pre-treatment where needed
  • Weeds and moss removed from the joints

What we look at first in Cardiff

  • Shade and drainage, which affect regrowth
  • Whether any blocks are loose or sunken first
  • How much joint sand is left
  • Whether the paving is permeable (no sand, no sealing with the wrong product)
  • Type of block and its age

The dig and sub-base in writing

Cleaning in Cardiff: 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 much does a block paving cleaning job cost in Cardiff?

Guide price for Cardiff: £2.50–£4.50 per m² including VAT, with a minimum charge for small areas.

How often should block paving in Cardiff 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.
