Mastic man in Hertford

Your local mastic man for Hertford

If you live in Hertford, there’s a good chance your home sits inside the conservation area. Designated in January 1967, it covers about 276 hectares, far larger than most, and contains 277 listed buildings. That shapes the way sealant work is done here: frames aren’t square, walls are often older than they look, and the finish has to suit the building as well as keep the weather out.

Mr Mastic covers Hertford from our base in Crawley. We reseal baths, showers and kitchens, renew the mastic around windows and doors, and seal external joints on homes of every age, from timber-framed houses in the centre to the newest flats on the edge of town. Each job starts with the old sealant cut out in full and the joint cleaned and dried, never a new bead over the old one.

Timber frames behind later fronts

Hertford’s town centre keeps its medieval street pattern, and many of its buildings are timber-framed behind later brick or rendered frontages, especially along St Andrew Street. Fore Street and North Road have their share of listed houses too. In homes like these, bathrooms have usually been fitted into rooms never meant for them, the floors move a little underfoot and the walls bow. A bath or shower tray set against an uneven wall leaves a gap that varies along its length, so we choose a sealant and nozzle size to suit it, and where the look matters we offer colour-matched resealing instead of plain white.

North of the centre, Bengeo sits on the ridge above Hartham Common, and Hertingfordbury, to the west, became part of the borough in 1935. Sele Farm, on the hill between the Mimram and the Beane, is a mix of social and private housing, and the Pinehurst estate adds more family homes. Bathrooms and kitchens in these houses have been refitted over the years, and the sealant we remove ranges from tired but sound to completely failed.

The town is still growing. Calton Court at Sele Farm opened in 2013, and further homes are planned at Archer’s Spring and Bacon’s Farm. New homes settle in their first year or two, and builders’ sealant often needs replacing early.

• Bathroom & kitchen resealing: Baths, showers, basins, wet rooms, worktops and sinks: old sealant cut out, mould treated and a new bead of anti-fungal silicone laid.
• Window & door mastic: Frame perimeters inside and out resealed with flexible, colour-matched sealant, with backing rod where the gap is deep.
