Mastic man in Whitstable

Resealing and mastic work across Whitstable

Whitstable is a working harbour town as well as a seaside one, with narrow alleys running down to the beach, Victorian streets behind the seafront and quieter suburbs in Tankerton, Chestfield and Swalecliffe. Mr Mastic is based in Crawley and covers Whitstable, resealing bathrooms and kitchens, renewing window and door mastic and sealing external joints exposed to the north Kent coast.

The most common call we get from coastal homes is about black mould on shower and bath sealant. Once mould has grown into silicone, it can’t be cleaned out, so the only real fix is to strip it and start again. Our anti-mould resealing service uses anti-fungal sanitary silicone, and we always remove every trace of the old bead first.

Island Wall cottages, town streets and newer suburbs

Some of Whitstable’s oldest homes stand closest to the sea. Island Wall, the street nearest the seafront, has many mid-19th-century buildings, and along the sea wall you’ll find small timber-framed, weatherboarded fishermen’s stores dating from the same era. Timber moves with the weather, and joints around windows and doors on these buildings need a sealant flexible enough to follow it. The Whitstable Town Conservation Area, designated in 1969, has 57 listed buildings, so on painted joinery we may suggest a paintable sealant rather than silicone.

Behind the seafront, terraced streets fill the town centre, and many of their bathrooms have been squeezed into small rear rooms. Further east, Tankerton, Swalecliffe and Chestfield are quieter residential areas, and many homes across the town now have replacement windows whose mastic has hardened after years of coastal sun.

The town is still growing, with the council’s local plan allocating sites off the Thanet Way and south of Ridgeway. Brand-new homes settle as they dry out, and the sealant around baths and showers often needs redoing early. Whatever the age of the house, we fill the bath before sealing it, so the bead is laid with the bath at its heaviest and is less likely to tear when it is next used.
