Your local mastic man for Stubbington
At the start of the 20th century, Stubbington was a handful of cottages and farms around a green. Today it is a large village in the borough of Fareham, between Titchfield, Lee-on-the-Solent and the coast at Hill Head, with housing estates spread over the fields that once surrounded it. The green, with its war memorial, is still the centre of village life. Mr Mastic covers Stubbington from our base in Crawley, resealing bathrooms, kitchens, windows and doors throughout the area.
Most of the calls we get from homes like these are about the bathroom: a bath seal that has turned black, a shower that has started to leak at the tray, or a basin that has pulled away from the wall. Each one is fixed the same way, by cutting out the old sealant in full and laying a clean new bead. Our article on leaking shower sealant explains the warning signs to look out for.
Village green, Crofton and the growing estates
The old village of Crofton was absorbed into Stubbington in the 19th century, and its name lives on in Crofton School and Crofton Old Church. By 1939 there were small shops around the green and the population was about 2,500. Since then, new estates have taken over many of the surrounding fields, and most of the homes you will find here are post-war houses and bungalows built in phases as the village grew.
That spread of decades shows up in bathrooms and kitchens. Older bungalows often have baths fitted against outside walls, which can encourage mould behind the seal. Later family houses frequently have showers over baths, where the screen and the sealant both take a battering. Kitchens refitted over the years tend to have worktop joints that have shrunk away from the tiles, and around the sink that small gap soon collects dirt and moisture.
To the south, Hill Head was once a fishing village. It now has homes close to the shingle beach, including the beach-front houses of Swordfish Close, built in 2004. These are the properties most exposed to coastal weather.

Bungalows, family houses and the Hill Head shore
Most Stubbington homes are low-rise, so access is easy and jobs are usually finished in a single visit. The bigger challenge is getting the right sealant in the right place. A bath that drops when filled needs a flexible bead and the bath filled while the sealant cures. A shower over a bath needs the screen seal and the wall joints checked together.
Down towards Hill Head, wind and salt from the Solent wear away window and door mastic faster than in the middle of the village. We take it out completely, clean the frames, and apply a weatherproof sealant designed to cope with exposed positions. Our bath resealing page sets out the inside work in more detail.
Schools, shops and the Daedalus site
Seven schools serve the area, including Crofton School and the Crofton Anne Dale and Crofton Hammond schools, and the village has a range of modern shops around the green. Between Stubbington and Lee-on-the-Solent, the former HMS Daedalus site is being redeveloped in stages, bringing new commercial buildings to the area.
Schools, shops and workplaces all have toilets, kitchens and shower rooms that need regular resealing. We can work in school holidays, before opening or after closing, and our construction sealant page covers work on new and refitted commercial buildings.

Your questions about mastic work in Stubbington
Do you cover all of Stubbington?
Yes. We cover the whole village, including Crofton and Hill Head, as well as nearby Titchfield and Lee-on-the-Solent.
We live near the beach at Hill Head. Do coastal windows need special sealant?
They benefit from a weatherproof sealant designed for exposed positions, and careful preparation so the joint bonds well.
Our bungalow bath keeps getting mould behind the seal. Why?
Baths on outside walls are colder and attract condensation. We treat the area and use an anti-mould sealant.
Can you work in a school during the holidays?
Yes. We can plan around term dates so toilets and changing rooms are ready for the new term.
Can you reseal a shower screen as well as the tray?
Yes. We reseal the tray, wall joints and the screen together so the whole enclosure is sound.
Do I need to be at home while you work?
It helps for us to be let in and shown the job, but you do not need to stay in the room.
Can you reseal around a toilet base and basin at the same time?
Yes. We usually check every joint in the bathroom and can reseal the toilet base, basin and bath in one visit.
