Block paving cleaning in Merthyr Tydfil: what to expect
Merthyr Tydfil is a sizeable town with a mix of semis, terraces and newer estates, and many drives here were first laid decades ago.
Hilly streets in much of Wales mean many drives slope, which shapes the falls, the edging and the water route.

What is included?
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.
- Optional biocide and sealer
- Kiln-dried sand brushed in once dry (re-sanding package)
- Rotary surface clean at a pressure that will not blow out the joints
- Weeds and moss removed from the joints
- Pre-treatment where needed

Cleaning in Merthyr Tydfil: questions
How much does a block paving cleaning job cost in Merthyr Tydfil?
Guide price for Merthyr Tydfil: £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.
