When Should You Re-Seal a Driveway?

The water-bead test

This is the quickest, most reliable way to check: pour a small amount of water onto a clean, dry section of the driveway. If the water beads up and sits on the surface, the seal is still working and protecting the material underneath. If it soaks in and darkens the surface rather than beading, the sealant has worn through and it's time to reapply.

Do this test in a few different spots, including higher-traffic areas like the wheel tracks and entry point, since sealant wears unevenly and one worn patch doesn't necessarily mean the whole driveway needs attention yet, though it's a useful early warning.

Visual and textural signs of wear

Fading colour, particularly on block paving or resin driveways where the original tone has visibly dulled compared to when it was laid or last sealed, is a common early indicator. A surface that feels rougher, more porous or chalky underfoot than it used to is another sign the protective layer has worn away and the base material is now exposed.

Increased staining that's harder to clean than usual, oil marks, tyre marks or general dirt sinking in rather than sitting on the surface and wiping off easily, also points to a seal that's no longer doing its job of keeping contaminants from penetrating.

Why timing depends heavily on use and exposure

A driveway used daily by multiple vehicles, exposed to regular oil drips, road salt in winter, and heavy foot traffic will wear through its sealant faster than a lightly used drive at the same age. Sun exposure also plays a role, with UV breaking down sealant over time even without heavy physical wear, so a sun-exposed driveway may need re-sealing sooner than a shaded one purely from weathering.

This is why the two-to-five-year range is genuinely a range rather than a fixed number, and why the water-bead test is a more useful guide for your specific driveway than any generic timeline.

Why cleaning always comes before sealing

Sealant applied over a dirty, algae-affected or stained surface traps that grime underneath a fresh glossy coat rather than fixing it, which looks fine briefly but stores up a worse problem for the next re-seal. A thorough clean, and full drying time, always needs to happen before any new sealant goes down, which is why re-sealing is usually offered as part of a full driveway clean rather than a standalone quick job.
