Resealing and mastic work across Abbots Langley
Abbots Langley is a village in name but a sizeable parish in practice, with 19,574 residents at the 2011 census and homes from almost every period. Getting old sealant out cleanly is half of every job here, whether it is a thick bead on a 1950s bathroom or builder’s silicone in a flat that is only a few years old.
Mr Mastic covers the whole parish from our base in Crawley, reached easily via the M25. We reseal baths, showers, basins, toilets and kitchen worktops, replace window and door mastic, and seal external joints. Our silicone removal service is often the first step, because new silicone only lasts when it goes onto clean, dry surfaces.
A medieval core, Victorian plots and a run of later estates
The Abbots Langley conservation area, designated in 1969, covers the medieval core around the Grade I listed Church of St Lawrence. After the Causeway House estate was sold in 1866, small builders filled plots along Breakspear Road, Adrian Road and Garden Road, joining the village to Kitters Green, and locally listed Victorian terraces from 1880 stand on the High Street.
The biggest change came with the 1950s, when a large post-war housing development added mostly semi-detached homes. Leavesden grew in phases: the Lemonfield estate in the 1950s, the Tudor Manor estate from the late 1980s, the former Leavesden Hospital site redeveloped as housing from the mid-1990s, and the Aerodrome Way estate this century. Hunton Bridge, with its own conservation area, has grown to the south and north in the last 40 years, and Bedmond is mainly detached and semi-detached homes.
Each era fails differently: Victorian joints crack with movement, post-war bathrooms carry layers of old sealant, and newer homes settle in their first years. Knowing which you have tells us which product and method to use before we start.

Hospital conversions, estate flats and the Gade valley
The former Leavesden Hospital buildings now hold many apartments, and the newer estates include flats too. In those blocks, bathroom sealant is shared responsibility in practice, because a leak affects the flat below. We work with managing agents to arrange access, and a cracked seal around a toilet pan is as worth fixing as one around a bath; our toilet base resealing service covers that.
Down in the Gade valley, around Hunton Bridge and the Grand Union Canal, homes sit in damper air and external mastic can age faster. We use weatherproof sealant around frames there and backing rod where gaps are deep. With most homes in the parish at one or two storeys, this work can usually be reached safely from the ground.
Village shops, schools and local landlords
Abbots Langley’s High Street and the parades in Leavesden have cafés, pubs and shops with small kitchens and customer toilets that need sound sealant. Schools and nurseries across the parish have washrooms and changing areas, and offices and business units around Leavesden have staff facilities that see daily use.
Rented homes and flats make up a good share of our work in places like this. Landlords call us between tenancies, and if you’re wondering when a seal needs replacing, our guide on how long silicone lasts will help.
