Mastic man in Eastleigh

Your local mastic man for Eastleigh

Eastleigh is a railway town. The station began as Bishopstoke Junction on the 1838 line from Southampton to Winchester, the carriage and wagon works moved here from Nine Elms in 1891 and the locomotive works followed in 1909. Its Victorian grid of streets still shapes the town centre. Mr Mastic covers Eastleigh and the rest of the borough from our base in Crawley.

We reseal baths, showers, sinks and worktops, replace failed window and door mastic and seal external joints. Each job is done properly: old sealant out, mould treated, joint dry, new bead in. If your shower tray is leaking into the room below, our article on leaking shower sealant explains what usually causes it.

A Victorian grid, 1920s suburbs and newer estates

The town centre’s grid-iron layout is so strong that the Swan Shopping Centre, opened in 1989, was built across it and closed off Market Street and High Street. Around it are the Victorian streets of the railway town. In these homes, bathrooms are often at the back of the house or in a later extension, and the bath may sit on a suspended timber floor that flexes. We fill the bath before sealing and use a flexible silicone so the joint can move with it.

Chandler’s Ford now forms most of the Eastleigh urban area. It was sparsely populated until the nineteenth century; building began in the 1920s around King’s Court, Merdon and Hiltingbury and spread later to Scantabout, Spring Hill and Oakmount, with Valley Park beyond. Bishopstoke and Boyatt Wood complete the urban area. These suburban houses tend to have had several bathroom refits, so we often find layers of old sealant to strip.

The borough has grown fast in recent years, and newer homes bring their own problem: builder sealant that fails within a couple of years as the house settles. Our new build snagging guide explains what to look for.
