Mastic man in Great Dunmow

Your local mastic man for Great Dunmow

Few towns in Essex have grown as quickly as Great Dunmow. Its population passed 10,600 at the 2021 census, and the town council’s list of housing schemes runs to more than twenty sites around Woodlands Park, Woodside Way, Stortford Road and Parsonage Downs. Mr Mastic covers Great Dunmow from our base in Crawley, and much of what we do here is fixing sealant in homes that are only a few years old.

The other half of the town is centuries older. Around the medieval market place, between the High Street and White Street, many houses date from the 16th and 17th centuries, when cloth and tanning made the town prosperous. Those homes need patient, careful work rather than a quick bead of white silicone, and we treat them that way.

Medieval centre, Church End and a ring of new homes

The historic core holds a dense run of listed buildings along High Street, Market Place, New Street and North Street, with the Old Town Hall in the market place itself. About half a mile north, Church End is the older settlement of the parish, a more rural group around the Grade I listed church of St Mary the Virgin, with buildings from the 14th to the 19th centuries. In houses like these, walls are rarely straight, floors move, and kitchens and bathrooms have been fitted into rooms never meant for them, so joints need a flexible sealant and a neat, considered finish.

Newer homes now ring the older town. Woodlands Park was built in several sectors, with around 480 homes in sectors one to three and another 125 in sector four. Land west of Woodside Way has been built out by Barratt and David Wilson Homes and by Bellway, with Smiths Farm, Parsonage Downs and other schemes adding hundreds more. Retirement flats have also gone up on the High Street.

In a new house, timber frames shrink and walls settle during the first couple of years, and builder sealant often splits along the bath, shower tray and kitchen worktop. Our guide to new build sealant snagging lists the joints worth checking before your developer warranty period runs out.
