Planning a block paving sealing job in Hertford
Hertford is a sizeable town with a mix of semis, terraces and newer estates, and many drives here were first laid decades ago.
Clay soils are common in parts of the East of England, so drainage and sub-base depth get extra attention.

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.
- Edges, walls and doors protected
- 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
- Second coat where the product requires it
