Sealing for Windsor Hospitality, Shops and Homes

Windsor has a busy town centre full of hotels, restaurants, cafes and shops that welcome visitors all year round, alongside period and historic properties and riverside homes along the Thames. Berkshire Mastic Man provides interior silicone and mastic sealing for businesses and homes across the town, as well as Eton, Datchet and Old Windsor.

Guest bathrooms, washrooms, restaurant kitchens and staff kitchens need sound, mould-resistant sanitary silicone that copes with heavy use and daily cleaning, and the work has to fit around the business. We agree the timing with you before we start, remove the old sealant, reseal every joint neatly and leave the area clean. In period homes, the same care goes into bathrooms, kitchens and the timber window boards and skirting of older rooms.
