Block paving cleaning and re-sanding

How we restore block paving

1. Inspect. We check for staining, moss, weeds and any loose or damaged blocks, and tell you about them before starting.
2. Deep clean. A rotary surface cleaner lifts dirt, moss and algae from the blocks and the joints without striping.
3. Treat. A biocide goes down to kill remaining spores and slow regrowth.
4. Re-sand. Once fully dry, fresh kiln-dried sand is brushed into every joint.

Why re-sanding matters

The sand in the joints locks the blocks together. Washing removes it, and leaving joints empty lets blocks shift and gives weeds an easy place to root. Fresh kiln-dried sand:

• locks the blocks together and reduces movement
• helps water drain through the joints
• makes it harder for weeds to establish
• gives a neat, finished look

More detail in our guide: why block paving needs re-sanding after pressure washing.

Prices

Minimum charge £180, which includes the biocide treatment and re-sanding. The final price depends on the area, how much moss and weed growth there is, how much sand the joints need and access.
