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
- Sealer applied evenly by roller or low-pressure sprayer
- Drying time and a date when cars can return
- Check that the paving is clean, re-sanded and dry
- Edges, walls and doors protected
How we find the cause
- Which sealer finish suits a slope or patio
- Whether the paving is permeable (no sand, no sealing with the wrong product)
- Type of block and its age
- Whether any blocks are loose or sunken first
- Moss, algae, weeds and oil staining

Sealing in Belfast: questions
How much does a block paving sealing job cost in Belfast?
Guide price for Belfast: £5–£14 per m² including VAT, with a minimum charge for small areas.
How often should block paving in Belfast 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.
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.
