Sealant jobs we do in Bishop's Stortford
Bishop’s Stortford is growing fast. To the old market town on the River Stort, the last few decades have added whole suburbs, riverside apartments and now thousands of new homes to the north. That mix keeps us busy: sealant in older houses that has done its time, and builder sealant in new ones that never quite did its job. Mr Mastic covers the town from our base in Crawley.
We reseal baths, showers, wet rooms and kitchens, and replace mastic around windows, doors and external joints. Whatever the age of the house, the old sealant comes out completely and the new bead suits the joint. If you are not sure how long yours should last, our guide on how long silicone sealant lasts gives a realistic picture.
A large conservation area ringed by newer suburbs
The town’s conservation area was designated in 1968 and is unusually large, at about 130 hectares, with 77 listed buildings including St Michael’s Church and the remains of Waytemore Castle. The streets climbing up Windhill from the centre, and the older roads around Hockerill east of the river, hold many of the town’s older houses. Malting was once the main local industry, and the town’s older buildings reflect that trading past.
Around that core are the suburbs of Thorley, Thorley Park, Havers, Snowley, Bishop’s Park and St Michael’s Mead, built over the second half of the 20th century and beyond. The Havers estate has been redeveloped with new houses and flats, and riverside apartments have been added near the centre. Bellway’s Goodsyard scheme alone has handed over more than 300 homes.
The largest change is to the north. Bishop’s Stortford North, including Stortford Fields and St Michael’s Hurst, has approval for around 2,679 homes, with building expected to continue until 2033. Homeowners there will see the usual first-year problems: shrinking sealant around showers, gaps at skirting and worktops, and cracked external mastic. Our article on new build sealant snagging lists what to check.
Riverside apartments, older terraces and new estates
In the apartment blocks by the river and in the town centre, a failed shower seal can damage the flat below long before you spot it. We can work with your managing agent to arrange access, and we take care in shared corridors and lifts. Parking near the centre is limited, so we plan visits with that in mind.
In the older houses within the conservation area, many windows are timber, and some are original sashes. External mastic there needs to suit the joinery and the brick or render, and painted frames sometimes need a paintable sealant rather than silicone. On the newer estates, large uPVC and aluminium glazing is common, and we cut out shrunken or gappy mastic and replace it with a flexible weatherproof sealant.
Shops, schools and the Stansted corridor
Stansted Airport lies about two and a half miles east of the town centre, and hotels, offices and logistics businesses along that corridor have bathrooms and washrooms in constant use. We can reseal room by room so most rooms stay in service; our hotel sealant page explains how.
In town, the rebuilt Jackson Square shopping centre, the shops and restaurants of the centre, and schools such as Bishop’s Stortford College all have kitchens and washrooms that need attention from time to time. With so many commuters and airport workers renting, we also do plenty of resealing for landlords between tenancies.

What we do in Bishop's Stortford
- 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: Cracked or shrunken mastic around window and door frames, sills and patio doors replaced with a weatherproof sealant.
- Commercial & hotel sealant: Commercial washrooms, kitchens and wet areas resealed floor by floor, so only a few rooms are out of use at once.

- Fire-rated sealant: Intumescent and fire-rated joints around pipes, cables and frames, installed to the manufacturer’s tested specification.
- External & façade joints: Split or perished joints in walls and cladding replaced with exterior sealant designed to stretch with the building.
- New-build mastic & snagging: Failed builder sealant in new homes put right, and plot mastic for developers.
- Floor & skirting joints: Skirting-to-floor gaps, tiled floor movement joints and concrete floor joints sealed with the right product.
- Regrouting: Crumbling grout in showers and wet areas raked out and refilled, so water stays out of the wall behind.
- Glazing & conservatory sealant: Leaking conservatory and rooflight joints, glass panels and shower screens resealed with silicone made for glass.
- Gutter, fascia & soffit sealing: Dripping gutter joints and end caps, and gaps at fascias and soffits, sealed with weatherproof exterior sealant.
- Sand mastic for sash & case windows: Traditional sand mastic for period windows and doors where a modern sealant would look out of place.
