Mastic man in Blackfield

Mastic and sealant work in Blackfield

Blackfield is a village on the Waterside, in the parish of Fawley and the New Forest district, with Langley as its neighbour and the Fawley refinery a short way to the north. Close to 5,850 people lived here at the 2021 census. Mr Mastic covers Blackfield from our base in Crawley, travelling down to reseal bathrooms and kitchens and to renew mastic around windows and doors.

We keep things simple. You get a clear quote, then we cut out every trace of old sealant, treat any mould, clean and dry the joint and lay a neat new bead in the right product. Sealing over the top of old silicone does not work, because the new layer cannot bond, so we never do it.

From red-brick cottages to refinery-era estates

The village is younger than most around it. Blackfield began in the late 19th century on moorland known as Hugh’s Common, where early mud cottages were later replaced by small red-brick houses. The big change came with the refinery: after it arrived in 1921, a quiet farming area turned into an industrial centre, and Blackfield and its neighbours grew into sizeable villages to house the people who worked there.

That gives Blackfield a lot of 20th-century family housing: semis, terraces and bungalows, many now on their third or fourth bathroom. The common faults are layers of old sealant left by earlier fitters, baths that have dropped slightly away from the wall, and tiled shower areas where the joints have opened. A full silicone removal and reseal sorts out all three.

Bungalows are worth a special mention. Their bathrooms are often used by older residents, where a sound seal around a level-access shower or wet room floor stops water spreading under the flooring. We take time over those joints, because a small gap at floor level can do far more damage than a crack higher up the wall.
