Block paving cleaning in Mountain Ash: the local picture
Mountain Ash is a smaller town, and many of its homes have more frontage to work with than city houses, which leaves room for borders and planting.
Hilly streets in much of Wales mean many drives slope, which shapes the falls, the edging and the water route.

What you get with our cleaning service
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.
- Pre-treatment where needed
- Weeds and moss removed from the joints
- Kiln-dried sand brushed in once dry (re-sanding package)
- Rotary surface clean at a pressure that will not blow out the joints
- Rinse down of edges, steps and walls

Cleaning in Mountain Ash: questions
Do you cover Treharris, Aberdare and Merthyr Tydfil?
Yes. We cover Mountain Ash and the places around it, including Treharris, Aberdare and Merthyr Tydfil, and the rest of Mid Glamorgan.
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.
