Silicone and Mastic Sealing Inside Homes and Businesses

Berkshire Mastic Man provides silicone sealing and mastic application inside homes and businesses across Berkshire. We replace mouldy and cracked sealant in bathrooms and kitchens, reseal the joints around window and door frames, and finish skirting boards, worktops, tiles and trims with a neat, even line.

Every job gets the same care: the old sealant removed, the joint cleaned and prepared, the right sealant for where it is going, and a clean, neat line to finish. We work across Reading, Slough, Bracknell, Wokingham, Maidenhead, Newbury, Windsor and Ascot, and the towns and villages around them.
