We offer a quality, power wash, cleaning service to block paving, slabs, concrete, tarmac & hard standing areas. Cleaning will remove weeds, moss, and lichen without the use of chemicals. Chemical agents would only be used for stubborn stains, oil etc. Following cleaning, blocked paving can be resealed. The sealing process is highly recommended as it helps to prevent further staining, seals in the sanded areas and restricts weed regrowth.
