Across Londonderry, front gardens range from narrow terrace plots to broad modern drives, and the best block, pattern and drainage choice changes with them.

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.
- Edges, walls and doors protected
- 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

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