Block paving sealing in Darlington: the local picture
Darlington has a big mix of housing, from older terraces near the centre to newer estates further out, so no two drives here start from the same ground.
Former colliery ground and clay soils occur across the North East, so the survey checks for soft spots before the sub-base depth is set.

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.
- 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
How we find the cause
- Whether the paving is permeable (no sand, no sealing with the wrong product)
- Moss, algae, weeds and oil staining
- Shade and drainage, which affect regrowth
- Whether any blocks are loose or sunken first
- How much joint sand is left
