Planning a block paving sealing job in Darwen
Darwen is a sizeable town with a mix of semis, terraces and newer estates, and many drives here were first laid decades ago.
Terraced streets across the North West often have very short frontages, so we check parking depth before quoting a conversion.

What does a block paving sealing job involve?
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.
- Second coat where the product requires it
- Check that the paving is clean, re-sanded and dry
- Sealer applied evenly by roller or low-pressure sprayer
- Drying time and a date when cars can return
- Edges, walls and doors protected
How we find the cause
- How much joint sand is left
- Which sealer finish suits a slope or patio
- Shade and drainage, which affect regrowth
- Moss, algae, weeds and oil staining
- Whether the paving is permeable (no sand, no sealing with the wrong product)
