Mastic man in Cheshunt

Mastic and sealant work in Cheshunt

A lot of Cheshunt stands where glasshouses used to be. Commercial nurseries were part of the town from 1806, and by 1967 the area had around a quarter of the country’s glasshouses. When the industry declined, most were redundant by the end of the 1970s, and many of the sites were redeveloped for housing. Add commuter homes from the 1930s, post-war estates and large new developments still under way, and Cheshunt has an unusually wide spread of house ages.

Mr Mastic covers Cheshunt and the rest of the Borough of Broxbourne from our base in Crawley. We reseal baths, showers and kitchens, renew window and door mastic and handle snagging on new homes. Every job starts by removing the old sealant fully and drying the joint, so the new bead bonds to a clean surface.

Commuter semis, overspill estates and new neighbourhoods

Commuter housing spread through Cheshunt from the 1930s, giving many streets their semi-detached and terraced houses. After the Second World War, several council estates were built, some on land bought by London boroughs for overspill housing. These homes have been modernised again and again, and the bathrooms we see often have replacement acrylic baths, showers over baths and sealant from more than one refit.

The former nursery sites brought later closes and cul-de-sacs, and the town is now growing fast. Cheshunt Lakeside, on the former Tesco head office site on Delamere Road, is planned for about 1,700 homes, and Brookfield Garden Village, west of the A10, was given permission in 2025 for more than 1,250. New homes settle, and the builder’s sealant around showers, baths and kitchens often cracks within a year or two. Our new build sealant snagging guide explains what to look for.

Churchgate, around the old parish church, is a conservation area with older buildings that need a gentler approach and a sealant that suits the frontage.

What we do in Cheshunt

• Bathroom & kitchen resealing: Every joint in the bathroom and kitchen, from the bath edge to the worktop, stripped back and resealed with anti-fungal silicone.
• Window & door mastic: Hardened, gappy mastic around frames, sills and French or patio doors cut out and renewed to keep draughts and rain out.
• Commercial & hotel sealant: Sealant programmes for offices, hotels, care settings and schools, with early or late working where it helps.
• Remedial sealant & repairs: Leaks and lifting beads from earlier sealant jobs put right, starting with finding out why they failed.
• Fire-rated sealant: Fire-rated sealant for service penetrations and frame gaps where it has been specified, applied to the tested details.
• External & façade joints: Expansion joints in brick, render and cladding cut out and renewed at the right depth so they can move without splitting.
• New-build mastic & snagging: Failed builder sealant in new homes put right, and plot mastic for developers.
• Floor & skirting joints: Gaps under skirting boards, tile movement joints and concrete floor joints sealed with a product that suits the traffic.
• Regrouting: Shower and splashback grout replaced where it has cracked or stained, with silicone in the movement joints.
• Glazing & conservatory sealant: Leaking conservatory and rooflight joints, glass panels and shower screens resealed with silicone made for glass.
• Gutter, fascia & soffit sealing: Exterior joints at gutters, fascias and soffits resealed to stop drips and staining down the wall.
