Block paving sealing in St Albans: what to expect

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

Flat ground across much of the East means falls have to be built in carefully so water does not sit on the drive.

What you get with our sealing service

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.

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

How we find the cause

  • Walls, doors and planting to protect
  • 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

Sealing in St Albans: questions

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.

Do you cover Harpenden, Hatfield and Hemel Hempstead?

Yes. We cover St Albans and the places around it, including Harpenden, Hatfield and Hemel Hempstead, and the rest of Hertfordshire.

How often should block paving in St Albans 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.
