Block paving sealing in Treharris: what to expect
In and around Treharris, 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.
How much does a block paving sealing job cost in Treharris?
For Treharris, our guide is £4.50–£14 per m² including VAT, so a 50 m² drive is likely to be £235–£700. Smaller jobs cost more per square metre because set-up and waste costs do not shrink with the area.

What you get with our sealing service
Sealing block paving means applying a clear liquid sealer to clean, dry paving. A good sealer soaks into the blocks and the jointing sand, binding the sand so it does not wash out, reducing staining and making the surface easier to keep clean. Some sealers also deepen the colour or leave a light sheen.
- Drying time and a date when cars can return
- Check that the paving is clean, re-sanded and dry
- Sealer applied evenly by roller or low-pressure sprayer
- Edges, walls and doors protected
- Second coat where the product requires it

Sealing in Treharris: questions
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.
