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 sealing job involve?

Sealing block paving means applying a clear liquid sealer to clean, dry paving. A good sealer soaks into the blocks and the jointing sand, binding the sand so it does not wash out, reducing staining and making the surface easier to keep clean. Some sealers also deepen the colour or leave a light sheen.

  • Second coat where the product requires it
  • Check that the paving is clean, re-sanded and dry
  • Drying time and a date when cars can return
  • Sealer applied evenly by roller or low-pressure sprayer
  • Edges, walls and doors protected

How we find the cause

  • Moss, algae, weeds and oil staining
  • Type of block and its age
  • Shade and drainage, which affect regrowth
  • Which sealer finish suits a slope or patio
  • Walls, doors and planting to protect

Sealing in North Watford: 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 sealing job cost in North Watford?

Guide price for North Watford: £5.50–£16 per m² including VAT, with a minimum charge for small areas.

How often should block paving in North Watford 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.
