Clean, Neat Sealing for Homes and Businesses
Berkshire Mastic Man provides professional silicone sealing and mastic application for homes and businesses across Berkshire, from Reading, Slough and Bracknell to Newbury, Windsor and Ascot.
Sealant keeps water out of the joints around baths, showers, basins and worktops, closes the gaps around window and door frames, and gives skirting, trims and tiled edges a clean finish. Once it cracks, discolours, grows mould or comes away, it stops doing that job.
We cut out the old sealant, clean and prepare the joint, then apply the right sealant for the job with a neat, even finish.
