Mastic man in Maldon

Mastic and sealant work in Maldon

Maldon sits on the tidal Chelmer beside the Blackwater estuary, with Heybridge across the river and a long, historic High Street at its heart. Homes here face sea air and wind as well as the usual wear inside, and sealant is one of the first things to show it. Mr Mastic is based in Crawley and covers Maldon, Heybridge and the villages around them.

Inside, we reseal baths, showers, basins and kitchen worktops, and outside we replace mastic around windows, doors and other joints. In kitchens we use a food-safe sealant by the sink and a colour that suits the worktop; our kitchen resealing page explains what is involved.

A listed High Street, the Basin and new garden suburbs

The Maldon conservation area was designated in 1969 and holds around 195 listed buildings, including the Moot Hall, the Blue Boar and many High Street properties. Heybridge Basin, where the Chelmer and Blackwater Navigation meets the estuary through locks, has its own conservation area. Older houses here often have timber frames, soft brick and uneven floors, so sealant joints are rarely straight or even. We take time to fill deep gaps properly and finish them neatly.

Between the old town and the countryside are 20th-century estates of semis, bungalows and terraces, many with bathrooms and windows last resealed a long time ago. Hardened mastic around uPVC frames lets in draughts and damp, and we replace it with a flexible, weatherproof sealant.

Maldon is also growing. Westcombe Park, formerly called the North Heybridge Garden Suburb, is planned for 1,138 homes, and Wycke Hill North, in the South Maldon Garden Suburb, has outline permission for up to 320. New builds often need sealant redone within a year or two, and our guide to new build sealant snagging shows what to look for.
