Sealing puts a protective film over or into a cleaned surface. Done at the right moment on the right material it holds colour, locks joint sand and makes future cleans easier. Done at the wrong moment it traps moisture and looks worse than doing nothing.
Sealing is usually worth it when
- You've just had block paving cleaned and re-sanded and want the joints to stay put.
- The drive is in full view of the street and you care about colour holding.
- Oil drips are a recurring problem and you want a surface that releases them more easily.
- You want to reduce how often the surface needs a full clean.
Sealing is usually not worth it when
- The surface is still damp or has just been laid and hasn't finished curing or efflorescing.
- You're moving imminently and just need presentation.
- The paving has structural problems — sinking, rocking blocks, failed sub-base — that need fixing first.
- The surface is a type where sealing can trap moisture and cloud, which we'll tell you about before quoting.
Matt or satin
Matt keeps the surface looking natural: cleaner, but not obviously coated. Satin lifts colour and gives a light sheen, which suits red and brindle block paving and looks deliberate rather than shiny.
Whichever you choose, it's a finish choice, not a performance one — both protect similarly.
What sealing will not do
It won't stop moss forming on the surface, it won't fix drainage, and it won't hold blocks that are moving. It reduces how fast dirt embeds; it doesn't make a surface self-cleaning.
