Block paving sealing in Llantrisant: the local picture
In and around Llantrisant, 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 is included?
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
- Second coat where the product requires it
- Check that the paving is clean, re-sanded and dry

Sealing in Llantrisant: questions
Do you cover Tonyrefail, Pontypridd and Pencoed?
Yes. We cover Llantrisant and the places around it, including Tonyrefail, Pontypridd and Pencoed, and the rest of Mid Glamorgan.
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.

Guide price for Llantrisant: £4.50–£14 per m² including VAT, with a minimum charge for small areas.

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.
