Mastic man in Richmond upon Thames

Resealing and mastic work across Richmond upon Thames

Richmond upon Thames sits on both banks of the Thames, a string of riverside villages running from Barnes, Mortlake and Kew through Richmond and Twickenham to Teddington and Hampton. Mr Mastic covers the whole borough from our base in Crawley, resealing bathrooms and kitchens, renewing window and door mastic and sealing external joints.

Much of the housing here is old and much loved, so the work has to look as good as it performs. We take care to remove old sealant without marking stone, tile or painted timber, then finish with a slim, even bead in a colour that suits the setting. Inside, that might be a roll-top bath in a Barnes villa or a shower in a Teddington riverside flat; outside, the mastic around a sash or a set of garden doors. Before any work starts, you’ll have a clear quote that sets out what we’ll do.

Eighty-five conservation areas and a lot of period property

The borough has 85 conservation areas, more than most in London. Around Richmond Green there are early 18th-century houses, while Barnes, East Sheen, Twickenham and Teddington are dominated by Victorian and Edwardian streets that grew after the railways arrived. St Margarets was laid out from 1854 as one of the first garden suburbs, and Teddington grew from about 1,200 people in 1861 to over 14,000 by 1901. Timber sash windows are everywhere, and the old mastic around them dries, cracks and lets draughts in. Our sand mastic service suits these frames.

Not everything is period. Whitton and Heathfield are mostly 1930s detached and semi-detached houses, built after Whitton station opened in 1930, where bathrooms and uPVC windows have usually been replaced more than once. Along the river, especially in Teddington, older riverside buildings have been turned into apartment blocks, and the former Teddington Studios site now holds modern flats and houses.

In Ham, the Ham Close regeneration is replacing 143 existing homes with a scheme of over 450. As new flats like these settle, their developer sealant in showers and kitchens is often the first thing to fail.
