Mastic man in Hemel Hempstead

Your local mastic man for Hemel Hempstead

Much of Hemel Hempstead was built from the late 1940s onwards, and bathrooms of that age have usually been refitted more than once. That often leaves us with layers of sealant to dig out, old silicone smeared over failed caulk, or a bath that has sagged and opened up the joint along the wall. Sorting those problems properly is what our remedial sealant work is for.

Mr Mastic covers every part of Hemel Hempstead from our base in Crawley. We reseal baths, showers, basins and kitchen worktops, replace hardened mastic around windows and doors, and seal external and floor joints on homes and commercial buildings. We cut out every trace of the old material before the new bead goes on, because fresh silicone will not bond to old.

A city in a park, built neighbourhood by neighbourhood

The government chose Hemel Hempstead as a new town after the Second World War and bought the land in February 1947. Geoffrey Jellicoe drew up the first plans. Adeyfield was the first new district to be started, Bennetts End began in 1951, and Chaulden and Warner’s End in 1953. Highfield came next, Gadebridge followed in the 1960s, and Grovehill, started in 1967, was the last of the original neighbourhoods. Woodhall Farm was built in the mid-to-late 1970s.

The new town absorbed older settlements too: Boxmoor, Apsley, Leverstock Green and Nash Mills, while the Old Town keeps its own conservation area. Much of the new town was built in a modernist style, including experimental house types, and some have aged better than others. Flat roofs, panel joints and large window openings all depend on sound mastic.

Newer homes are on the way: land west of Chaulden and Warner’s End has been released for around 900 houses, and new builds of every size need their sealant checked in the first year or two.
