Block paving sealing in Bangor, Gwynedd: what to expect

In and around Bangor, Gwynedd, village-style frontages sit alongside newer cul-de-sacs, so the right block often depends on the age of the house.

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

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
  • Edges, walls and doors protected
  • Sealer applied evenly by roller or low-pressure sprayer
  • Check that the paving is clean, re-sanded and dry

Sealing in Bangor, Gwynedd: questions

How often should block paving in Bangor, Gwynedd 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.

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.
