Block paving sealing in Mountain Ash: what to expect
In and around Mountain Ash, village-style frontages sit alongside newer cul-de-sacs, so the right block often depends on the age of the house.
Wales is wetter than most of England, and new front paving has to be permeable or drain within the property, so drainage is designed in from the start.

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

Sealing in Mountain Ash: questions
How often should block paving in Mountain Ash 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.
