We use very high pressure water with a rotary cleaner to blast off the years of dirt and weathering from all types of exterior hard surfaces including:- Block Paving, Concrete pavers, stone & wood decking. We do not use any harmful chemicals for the normal cleaning process, just water. Cleaning will remove weed and we can apply a suitable weed killer to help subsequently keep them under control. Block paving jointing sand is replaced and leaves that just laid look. We have also had success in removing oil stains from paving with the additional use of a chemical de-greasing agent. We can also apply specialist sealants to block paving to protect it from stains and help to inhibit weed growth. No job too big or small.
