Your local mastic man for Tring
Tring is a compact market town in the north-west of Dacorum, sitting in the Tring Gap surrounded by the Chilterns Area of Outstanding Natural Beauty. Its centre has been a conservation area since 6 October 1969, and a large share of its houses are Victorian or older. That means sash windows, brick and clay tile, chimney breasts in odd places and bathrooms fitted into rooms built for something else.
Mr Mastic covers Tring and the surrounding villages from our base in Crawley. We reseal baths, showers and kitchens, renew mastic around timber and uPVC windows and doors, and seal external joints where frames meet brick or render. On period houses we take extra care over the finish, because a wide, smeared bead of white silicone can spoil a frontage that has been looked after for a century.
Huckvale brick, sash terraces and Victorian villas
Dacorum’s appraisal splits the conservation area in two. The eastern half is the historic core around the High Street and Akeman Street, with town houses, old coaching inns and workers’ cottages from the late eighteenth and early nineteenth centuries. The western half is mainly mid to late Victorian, with rows of two-storey terraced houses on King Street, Chapel Street, Queen Street and Henry Street, many with double-hung sliding sashes, and larger villas on Park Road and Western Road.
Around 1900, the Rothschild estate and its architect William Huckvale shaped much of the town, with red brick, timber framing, tile-hanging and steep roofs. Louisa Cottages on Park Road are one example. Their casement windows, often with leaded lights, sit in brickwork that has moved over more than a century, and the joints around them need a sealant that stays flexible.
The appraisal also lists replacement uPVC windows as a negative feature, so many owners keep and repair their timber frames. Where you do have uPVC, the mastic round it is often the first thing to fail. Our window mastic guide explains the difference between the two jobs. Beyond the old town, there are post-war and later family homes, and around 250 new homes are proposed at Dunsley Farm.

Sashes, render and joints that need to look right
Timber sashes swell in damp weather and shrink in dry spells, and over the years the old putty-like mastic between box frame and brick dries out and drops away. We rake out the joint, fit backing rod where the gap is deep, and use a sealant that can be painted where it will be seen. Render and painted finishes appear on some Tring buildings, and the junction between render and frame is another place cracks open.
For walls, sills and the gaps where an extension meets the original house, our external joint sealing uses weatherproof, flexible products set at the right depth. Inside, older cottage kitchens with uneven walls benefit from careful kitchen resealing along worktops and upstands.
Schools, hotels, shops and rented homes
Tring School on Mortimer Hill has around 1,500 pupils, and Tring Park School for the Performing Arts occupies Tring Park Mansion. Schools like these have washrooms and changing areas that need resealing in the holidays. Pendley Manor, east of the town near the station, operates as a hotel and conference venue, and the shops, pubs and cafés along the High Street all have kitchens and toilets.
For landlords and letting agents, we can reseal between tenancies and quote for several properties together.

Questions we’re asked in Tring
Do you cover all of Tring?
Yes. We cover the town and its conservation area, Little Tring, New Mill, Hastoe and the area around Tring Station, plus Long Marston and Wilstone.
Can you seal around my original timber sash windows?
Yes. We rake out the old mastic, use backing rod where needed and apply a flexible sealant that can be painted to match the frames.
I live in the conservation area. Do I need permission for window mastic?
Like-for-like resealing of an existing joint is normally routine, but if you’re changing anything visible we’d suggest checking with Dacorum Borough Council first.
Can the sealant be coloured to suit brick or stone?
Yes. We carry a range of colours for external joints, so the new bead doesn’t stand out against the wall.
Can you reseal a school’s washrooms during the holidays?
Yes. Holiday work is ideal, as the sealant can cure before pupils return.
My cottage bathroom walls aren’t straight. Will the seal look messy?
It shouldn’t. We size the bead to the gap along its length and tool it neatly, even where the wall curves.
Do you reseal kitchens in older cottages?
Yes. We renew worktop, upstand and sink joints, sizing the bead to suit uneven walls.
Do you give a guarantee?
Yes. Every job comes with our one-year guarantee.
