Professional Interior Sealing Wherever You Are in Berkshire

Berkshire Mastic Man provides interior silicone and mastic sealing for homes and businesses across the whole of Berkshire. From Victorian terraces in Reading and new-town estates in Bracknell to riverside apartments in Maidenhead, hotels in Windsor, period homes in Newbury and offices on the Slough Trading Estate, we cover the county from end to end.

Wherever the job is, the standard is the same. The old sealant is removed, the joint is cleaned and prepared, and the right sealant goes in: sanitary silicone with a fungicide for bathrooms, kitchens and washrooms, a flexible sealant where window and door frames meet the plaster, and a paintable sealant for skirting, architraves and any joint that will be decorated.

  • Every town and village in Berkshire
  • Homes, flats and rental properties
  • Offices, shops and commercial units
  • A clean, neat and professional finish

Berkshire Properties

Sealing for Every Kind of Berkshire Property

Berkshire has a wide mix of buildings, and the rooms inside them each need the right approach:

  • Victorian and Edwardian terraces in towns such as Reading, Windsor and Newbury, with older bathrooms, and timber window boards and skirting that have moved away from the plaster
  • Post-war housing in Slough and new-town estates in Bracknell, where bathrooms, kitchens and the internal joints around replacement windows and doors need renewing
  • Large newer developments around Wokingham and Bracknell, where new homes settle and open gaps at baths, worktops and skirting
  • Thames-side homes and riverside apartments in Maidenhead, Windsor and Reading, with bathrooms, en-suites and communal areas to keep in good order
  • Larger detached and period homes around Ascot, Sunninghill and Sunningdale, with several bathrooms, kitchens and utility rooms
  • Offices, shops, hotels and restaurants, from washrooms on the Slough Trading Estate to guest bathrooms and kitchens in Windsor

Whatever the property, we match the sealant to the joint and finish every line neatly. Read more about silicone sealing and mastic application, bathroom and kitchen resealing, window and door sealing, interior sealing and commercial and residential sealing, or see all our sealing services.
