What is included?
Sealing only works on paving that has been cleaned and re-sanded first and is completely dry, so it is usually part of a clean, re-sand and seal package. It is not permanent: most sealers need renewing every three to seven years as they wear in the wheel tracks, and new paving should be left for a few months before sealing so moisture and any white efflorescence can clear.
- Check that the paving is clean, re-sanded and dry
- Edges, walls and doors protected
- Drying time and a date when cars can return
- Sealer applied evenly by roller or low-pressure sprayer
- Second coat where the product requires it

Sealing in Castlereagh: questions
How much does a block paving sealing job cost in Castlereagh?
Guide price for Castlereagh: £5–£14 per m² including VAT, with a minimum charge for small areas.
Do you cover Belfast, Newtownabbey and Lisburn?
Yes. We cover Castlereagh and the places around it, including Belfast, Newtownabbey and Lisburn, and the rest of County Antrim.
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.
