Your local mastic man for Halstead
Halstead grew up at a crossing of the River Colne and became the market town for this stretch of north Essex. Its buildings are a mix of medieval timber frames, Victorian brick terraces put up for mill workers, and twentieth-century houses climbing the valley sides. Mr Mastic covers Halstead from our base in Crawley, resealing bathrooms and kitchens, and renewing the mastic around windows and doors.
Many of the homes we are asked to look at have had a new bathroom fitted over old sealant, or new silicone run straight over the top of old. That never lasts. Silicone will not bond to silicone, so the new bead peels and the mould behind it comes through again. Our article on sealing over old silicone explains why we always strip back to a clean joint.
Market Hill, Courtauld terraces and the valley estates
The historic core has been a conservation area since 1969, and Braintree District Council counts 102 listed buildings in the town. Several on Market Hill contain 14th-century structure, and St Andrew’s Church on the High Street is the only Grade I listed building. In old timber-framed houses, walls, floors and frames all move a little, so a rigid bead around a bath or window will crack within a season.
The textile firm Courtaulds shaped much of the town’s Victorian and later housing. Factory Terrace, built in 1872 for the firm’s workers, is a row of three-storey houses; the cottages at 3–12 The Causeway, built in 1883 in red brick, are Grade II listed. In the 1920s and 1930s, Samuel Augustine Courtauld built more than fifty Arts and Crafts houses in the town, and much of the firm’s built estate is now on a local heritage list. These houses tend to have small original bathrooms that have since been refitted, often with a modern bath in an old, uneven alcove.
Around the edges, twentieth-century estates and newer infill bring the usual issues: acrylic baths, shower trays with too little sealant, and replacement windows whose mastic has aged in the sun.
Listed walls, uneven alcoves and colour
In a listed or conservation area property, the sealant should be noticed as little as possible. Bright white silicone against an old, off-white wall or a cream bath can look out of place, so we often use a closer shade through our colour-matched resealing. Where a joint is wide or uneven, as it often is in an old alcove, we pack it first so the bead is the right depth and does not sag.
Converted flats above shops on the High Street share floors with the business below, and a leaking shower can damage stock or a ceiling. We are happy to coordinate access with both the flat and the shop.
High Street businesses and Bluebridge Industrial Estate
Halstead is one of the three main town centres in Braintree District, with independent shops and a long-standing role as an antiques centre. Many of those businesses work out of old buildings with small, well-used staff toilets and kitchens.
On the edge of town, Bluebridge Industrial Estate holds workshops, warehouses and light industrial units, where welfare showers and kitchens take hard daily use. We can reseal outside working hours so staff are not left without facilities. For window frames in those units, our window and door mastic service covers aluminium and uPVC as well as timber.

Questions we’re asked in Halstead
Do you cover all of Halstead?
Yes. We cover the whole town, from the High Street and Market Hill to the outer estates, and nearby villages such as Greenstead Green and Sible Hedingham.
My cottage is listed. Will resealing the bathroom affect that?
Resealing a bath or shower is routine upkeep. If you are changing anything outside, check with the council first; we will match the sealant to the look of the house.
Can you match the sealant to my cream bath?
Yes. We can use a coloured sanitary silicone that sits closer to the bath and tiles than bright white.
The gap behind my bath is very uneven. Can it still be sealed?
Yes. We fill deep or uneven gaps first so the sealant is the right depth and holds its shape.
Can you reseal welfare showers at a unit on Bluebridge?
Yes. Out-of-hours visits can be arranged so staff facilities are only out of use briefly.
My flat is above a shop. Who do you need to speak to?
Just you, usually. If access through the shop is needed we can arrange that with the owner.
Do you use anti-mould sealant?
Yes. In bathrooms and kitchens we use sanitary silicone with fungicide to slow mould coming back.
