What is included?
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.
Wet winters in Northern Ireland make falls, edge restraints and full joints especially important.
- 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
- Drying time and a date when cars can return
How we find the cause
- Walls, doors and planting to protect
- Whether the paving is permeable (no sand, no sealing with the wrong product)
- Which sealer finish suits a slope or patio
- How much joint sand is left
- Shade and drainage, which affect regrowth

Sealing in County Down: questions
Do you cover Bangor, County Down, Newtownards and Newry?
Yes. We cover all of County Down, including Bangor, County Down, Newtownards and Newry.
How often should block paving in County Down 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.
