Block paving sealing in Barnet: what to expect
Barnet is a sizeable town with a mix of semis, terraces and newer estates, and many drives here were first laid decades ago.
Many London streets have controlled parking and narrow frontages, so we measure the car space and the crossover before anything else.

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

Sealing in Barnet: questions
How much does a block paving sealing job cost in Barnet?
Guide price for Barnet: £6–£18 per m² including VAT, with a minimum charge for small areas.
How often should block paving in Barnet 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.
