Planning a block paving cleaning job in Carmarthen
Around Carmarthen, plots are often larger and drives longer, so edging, falls and the route the water takes need planning.
Wales is wetter than most of England, and new front paving has to be permeable or drain within the property, so drainage is designed in from the start.

What does a block paving cleaning job involve?
Block paving cleaning removes moss, algae, weeds and ground-in dirt from the surface and the joints, usually with a rotary surface cleaner on a pressure washer, which cleans evenly without the stripes a hand lance leaves. A biocide treatment can be applied to slow regrowth.
- Kiln-dried sand brushed in once dry (re-sanding package)
- Optional biocide and sealer
- Rotary surface clean at a pressure that will not blow out the joints
- Rinse down of edges, steps and walls
- Weeds and moss removed from the joints
How we find the cause
- Walls, doors and planting to protect
- Whether the paving is permeable (no sand, no sealing with the wrong product)
- Moss, algae, weeds and oil staining
- Whether any blocks are loose or sunken first
- Which sealer finish suits a slope or patio

Cleaning in Carmarthen: questions
How often should block paving in Carmarthen be cleaned?
Every two to four years for most drives, more often for shaded or north-facing paving.
How much does a block paving cleaning job cost in Carmarthen?
Guide price for Carmarthen: £2.50–£4.50 per m² including VAT, with a minimum charge for small areas.
Can you seal my drive straight after cleaning?
Only once it is completely dry and re-sanded. Sealing damp paving traps moisture and can leave a white bloom.
Will cleaning damage my block paving?
Not when it is done with a rotary cleaner at medium pressure and the joints are re-sanded afterwards. High-pressure lances held close are what cause damage.
