Block paving sealing in Nelson, Mid Glamorgan: what to expect
In and around Nelson, Mid Glamorgan, village-style frontages sit alongside newer cul-de-sacs, so the right block often depends on the age of the house.

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.
- Edges, walls and doors protected
- Check that the paving is clean, re-sanded and dry
- Second coat where the product requires it

Sealing in Nelson, Mid Glamorgan: questions
How often should block paving in Nelson, Mid Glamorgan be cleaned?
Every two to four years for most drives, more often for shaded or north-facing paving.
Do you cover Treharris, Pontypridd and Mountain Ash?
Yes. We cover Nelson, Mid Glamorgan and the places around it, including Treharris, Pontypridd and Mountain Ash, and the rest of Mid Glamorgan.
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.
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.
