Block paving earns its popularity by being repairable and long-lived, but it is not maintenance-free, and the gap between a drive that looks tired at five years and one that looks fresh at fifteen is mostly habits rather than luck.
M&R Property & Paving Services lays and restores block paving in Chertsey, and this is the honest care routine: little, seasonal, and none of it complicated.
What the joints are doing, and why sand matters
Block paving works as a system: the blocks carry the load, and the sand in the joints locks them together so forces spread sideways. When joints empty, through washing, sweeping or ants, blocks start to move individually, edges chip and the surface begins its slow decline.
So the single most valuable maintenance task is unglamorous: keep the joints full. After any deep clean, and every couple of years regardless, brush kiln-dried sand across the surface into the joints. It costs little, takes an afternoon, and it is the first thing M&R Property & Paving Services checks on any tired drive, because it is the difference between a surface and a collection of loose blocks.
- Full joints are structural, not cosmetic.
- Re-sand after any pressure wash, always.
- Brush sand in dry weather so it actually fills the joint.
Weeds and moss: cause, not just symptom
Weeds in block paving rarely grow up from below; they grow down from above, seeding into the organic dust that settles in joints. Moss likewise follows shade and damp rather than indicating failure. Regular brushing denies both their seedbed, which beats any amount of chemistry afterwards.
Where growth has taken hold, get it out roots and all, clean, and re-sand. On persistent problem drives a joint stabiliser or polymeric sand in the worst areas can slow re-colonisation, provided the drainage through the joints is respected.
- Brush monthly in leaf-fall and seed seasons.
- Remove established weeds by the root, then refill the joint.
- Cut back overhanging shade where moss keeps returning.
Pressure washing without wrecking it
A pressure washer is both the best cosmetic tool and the fastest way to ruin a block drive. Held too close or too fiercely it strips joints, scars block faces and drives water under the surface. Used sensibly it lifts years of grime in a morning.
The sensible version: moderate pressure, a fan pattern, held at a shallow angle and a consistent distance, working diagonally to the joint lines. Then, once dry, re-sand every joint you have just emptied. Washing without re-sanding is how well-meaning owners dismantle their own driveways.
Sealing, stains and the five-minute habits
Sealing is optional, not obligatory. A quality sealer deepens colour, slows staining and hardens joints, at the cost of periodic reapplication and a surface that must be properly clean and dry first. On oil-prone parking spots it earns its keep; on a lightly used drive it is a preference, not a need.
The habits matter more. Drip trays under leaky vehicles, oil spills lifted quickly with absorbent granules rather than scrubbed wet, leaves off the surface before they compost into the joints, and a glance at the edges each spring for any block starting to work loose. A loose edge block re-bedded early is a ten-minute fix; ignored, it recruits neighbours.

Questions customers ask
How often should block paving be re-sanded?
After every pressure wash without exception, and roughly every two years otherwise. If you can see daylight down a joint, it is due.
Does sealing block paving stop weeds?
It slows them by binding the joint surface, but it is not a permanent barrier and it never substitutes for full joints and regular brushing. Treat it as a finish, not a force field.
Can single stained or damaged blocks be replaced?
Yes, and this is block paving's quiet superpower: individual blocks lift and swap invisibly, which is why keeping a few spares from the original job is always worth doing.
Keep the joints full, the surface brushed and the washer at a respectful distance, and block paving repays the small effort for a very long time.
