Sealant jobs we do in Ware

Few towns of its size have as many old buildings as Ware. Its long High Street and the lanes off it hold more than 200 listed buildings, from timber-framed houses on Crib Street to former maltings tucked behind the shops. Alongside them are the estates and newer homes that have grown up round the town. Mr Mastic covers all of Ware from our base in Crawley, resealing bathrooms and kitchens and renewing window, door and external joints.

Old and new buildings need different sealants, and choosing the right one matters as much as how it is applied. A modern silicone that suits a shower tray in a new house can be the wrong choice next to old brick or timber. We look at the surfaces first, take out every trace of the old sealant, then pick a product that will last on that joint.

Maltings, timber frames and a growing town

Ware was once the leading malt-making town in Hertfordshire: the 1880 Ordnance Survey map shows 107 malt kilns, and the last working malting, at Broadmeads, closed only in 1994. Many former maltings survive, some listed, and several have been turned into homes, studios and other uses. Ware has 202 listed buildings in all, including three at Grade I, and the riverside is lined with 18th-century gazebos behind the High Street, several recently restored.

Converted maltings are full of character but often awkward for bathrooms: thick brick walls, uneven floors and very little natural ventilation. Showers squeezed into these spaces can suffer heavy condensation, so we use anti-fungal sanitary silicone and make sure the joint is bone dry before we start. In timber-framed houses, baths sit on floors that move, and a stiff bead will tear, so a flexible product and the right technique matter.

Beyond the centre, Ware has extended steadily with 20th-century and modern estates, and Amwell End forms its southern suburb. Land north and east of Ware is allocated in the East Herts District Plan for at least 1,000 new homes, with a possible 500 more. As those homes are occupied, our new build mastic service covers the sealant that fails as a new house settles.

Listed buildings, narrow yards and the riverside

Working in Ware’s historic core often means narrow passageways between High Street buildings, upper-floor flats reached by steep stairs and limited parking close by. We bring what we need on foot where we have to, and we plan visits so materials are not left in a shared yard. In listed buildings, we stick to like-for-like repairs and avoid anything that would damage historic surfaces.

Riverside homes and those with older brickwork need extra care with external joints. Where a frame meets soft old brick, we remove crumbling mastic gently, use backing rod for deep gaps and apply a flexible, weatherproof sealant. Our external joint sealing page explains the method.

GSK, shops and rented homes

GSK is Ware’s main employer, with large manufacturing and research sites on ground first developed by Allen & Hanburys from 1898. Sites like these, and the many smaller offices and workshops in the town, have washrooms, kitchens and welfare areas where hygienic, durable sealant is essential. We can work out of hours and use anti-bacterial products where they are needed.

The High Street’s pubs, cafés and shops, and the town’s schools and community buildings, all have facilities that need resealing from time to time. We also work for landlords and letting agents, resealing flats over shops and family homes between tenancies.

Ware: common questions

Do you cover all of Ware?

Yes. We cover the town centre, Amwell End and the estates around the town, plus nearby villages such as Wareside, Thundridge, Wadesmill and Widford.

I live in a converted maltings and my shower seal keeps going mouldy. Why?

These buildings often have poor ventilation, so moisture lingers. We remove the old bead, treat the mould, and reseal with anti-fungal silicone once the joint is fully dry.

Can you reseal a bath in a timber-framed house?

Yes. We use a flexible sanitary sealant and fill the bath while it cures, so the bead copes with the floor moving.

My home is listed. Can you still replace the window mastic?

Usually yes, as a like-for-like repair, but check with East Herts Council if you are unsure. We keep the work neat and avoid damaging old surfaces.

Do you work on the new homes north and east of Ware?

Yes. We reseal builder sealant that has cracked as a new house settles.

Can you reseal staff washrooms at an industrial site?

Yes. Out-of-hours working can be arranged, and we can use anti-bacterial silicone where required.

Do you also cover Hertford?

Yes. Hertford is just to the west of Ware and is part of our regular Hertfordshire area.
