Your local mastic man for Broadstairs
Seven bays line the coast at Broadstairs, from Dumpton Gap in the south through Louisa Bay, Viking Bay, Stone Bay and Joss Bay to Kingsgate Bay and Botany Bay, and the town sits on chalk above its little harbour with cliffs on either side. Inland are the village of St Peter’s, Reading Street and the Westwood area. Mr Mastic covers all of it from our base in Crawley, resealing baths, showers and kitchens and replacing tired window and door mastic.
Most of our work starts with a simple look: is the old sealant cracked, lifting, stained or mouldy? If it is, it comes out completely. We clean the joint, let it dry, and lay a new bead of anti-fungal silicone or weatherproof mastic, depending on where it is. For a walk-through of what we do inside, see our bathroom resealing page.
Flint, chalk and seafront terraces
The Town Council’s design statement describes terraces of grand Georgian and Victorian homes along the promenades, with rows of good Victorian and Edwardian terraced housing above Viking Bay and flint houses packed into the narrow streets behind. Many of the oldest cottages are flint or chalk, with Kent peg or slate roofs, and some chalk-built houses were finished in lime render to protect them from the weather. Broadstairs has had a conservation area since 1970, extended twice since.
St Peter’s has its own conservation area of narrow streets and flint walls, Reading Street is known for houses with Flemish gable ends, and Kingsgate, another conservation area, includes Kingsgate Castle, now converted into private homes. Away from the old cores, the town grew with post-war estates, such as those around Northdown Hill in St Peter’s.
On flint, render and old brick, the joint around a frame is rarely neat or even, so we fill deep gaps with backing rod and use a sealant that grips uneven surfaces. In converted seafront flats, bathrooms often sit on old timber floors that flex, and that movement splits a rigid bead. Filling the bath before sealing helps the new joint cope.
Cliff-top exposure and holiday lets in old houses
Houses on the cliff tops and along the bays take the full force of the weather off the sea, and external mastic on the most exposed faces hardens and cracks sooner than it would inland. Once a joint opens, wind-driven rain gets behind the frame and into the reveal. Sills and the joints under them need checking as well as the sides of a window.
Broadstairs has many older residents and many visitors, so a lot of homes have been adapted with level-access showers, and plenty of old houses are now flats or holiday lets. In a building of flats, we can work with the managing agent on access and keep noise and mess in shared stairwells to a minimum. For holiday lets, we time the work around changeovers.
Hotels, guest houses, Westwood Cross and colleges
Tourism is Broadstairs’ main business. The number of hotels has fallen over the years, but those that remain, such as the Royal Albion on the front, along with guest houses and holiday flats, have bathrooms that see heavy use through the season. We can reseal room by room so the rest of the building keeps trading, and our sealant for hotels page explains how.
At Westwood, the Westwood Cross development brings shops, restaurants, a cinema and a hotel. East Kent College also has a presence in the town, and the local schools have washrooms and kitchens that need resealing in the holidays.

Questions from Broadstairs
Do you cover all of Broadstairs?
Yes. We cover the town centre and Viking Bay, St Peter’s, Reading Street, Dumpton, Kingsgate and Westwood, and the rest of Thanet.
Can you seal around windows in a flint cottage?
Yes. Flint and old brick leave uneven gaps, so we use backing rod where needed and a sealant that grips irregular surfaces.
My cliff-top house’s window mastic has failed quickly. Why?
Exposure to wind, sun and salt spray dries sealant out. A flexible weatherproof sealant laid at the right depth lasts much better.
Can you reseal guest rooms one at a time?
Yes. We work room by room so the rest of the hotel or guest house can stay open.
Do you work on holiday lets between guests?
Yes. A changeover is ideal, as the sealant can cure before the next arrival.
Can you reseal a level-access shower?
Yes. We reseal trays, wet room floors and screens with anti-fungal sanitary silicone.
Do you need to remove the old sealant?
Always. New silicone won’t stick properly to old, so we cut it all out first.
