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

Sealing in Streatham: 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 Mitcham, Brixton and Wimbledon?
Yes. We cover Streatham and the places around it, including Mitcham, Brixton and Wimbledon, and the rest of Greater London.
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.
