Mastic man in Heathfield

Sealant jobs we do in Heathfield

Heathfield is a Wealden market town that grew out of the old village now known as Old Heathfield. The arrival of the Cuckoo Line railway in 1880 gave it a new lease of life, and the town kept expanding: the parish population more than doubled between 1961 and 2021. That mix of older village houses and a large share of post-1960s homes makes for a wide range of sealant jobs. Nearby, the 17th-century mansion of Heathfield Park and its Gibraltar Tower show how far back building here goes.

Mr Mastic covers Heathfield and the surrounding villages from our base in Crawley. We reseal baths, showers, basins and kitchen worktops, replace failed mastic around windows and doors, and seal joints outside where rain is getting in. On every job the old sealant comes out in full, because new silicone will not bond to old.

An old village at the heart of a growing town

Old Heathfield was the original settlement and is now just one part of the town. Around it, the growth that followed the railway and the big expansion of the later 20th century brought streets of family houses, bungalows and some flats near the High Street. Much of the town’s housing is therefore 40 to 60 years old, with bathrooms and kitchens that have been refitted more than once.

In those homes we often find sealant that has been patched over several times, leaving a thick, uneven bead with mould trapped underneath. Taking it back to clean tiles and resealing properly is the only lasting fix; our article on why sealant goes mouldy explains what is going on. Worktop joints that have shrunk back and replacement windows with brittle mastic are the other common calls.

Out in the villages of Heathfield and Waldron parish, including Waldron, Cross-in-Hand, Broad Oak, Punnetts Town, Cade Street and Little London, the houses are more varied, with older cottages beside later homes. Older walls are rarely square, so window and door joints can vary in width, and we use backing rod and a flexible sealant to suit.
