Mastic man in Horndean

Sealant jobs we do in Horndean

Horndean is a village that grew fast in the second half of the twentieth century, and a lot of its homes now have bathrooms, kitchens and windows on their second or third round of sealant. Mr Mastic covers Horndean from our base in Crawley, along with Catherington, Clanfield, Blendworth, Cowplain and Rowlands Castle. We reseal baths, showers, basins and worktops, renew tired mastic around frames and doors, and seal external joints that have opened up.

Every job starts the same way. The old bead is cut and scraped out completely, mould is treated, and the joint is cleaned and left dry before any new sealant goes on. A fresh line run over a failing one simply peels away, so we never do it. If your silicone has gone black within a year or two, our article on why sealant goes mouldy explains what is usually behind it.

Post-war estates, brewery flats and a retirement village

Much of Horndean’s housing dates from the decades after the war. The Hazleton estate, for example, was built in the early 1960s on what had been the grounds of Merchistoun Hall, the Grade II listed house that is now the village’s main community centre. Homes of that age have often had their bathrooms refitted more than once, and we regularly find layers of old silicone, baths that have dropped slightly on their frames, and replacement uPVC windows whose mastic has hardened and split.

The village centre has its own mix. Gales Brewery brewed here from 1850 until 2006, when the site was converted into shops and flats. Conversions like this often fit bathrooms into spaces that were never designed for them, so trays and screens sit on floors that flex, and a stiff bead soon tears. We use flexible sanitary silicone and load the bath or tray before sealing, so the joint is set at its widest.

More recently, the old Victorian workhouse site was redeveloped in 2017 and 2018 as a large retirement complex. Newer homes like these settle in their first few years, and the original sealant around showers and kitchens is often the first thing to crack.

What we do in Horndean

• Bathroom & kitchen resealing: Mouldy or split sealant around baths, shower trays, basins and sinks removed completely and replaced with a neat, hygienic bead.
• Window & door mastic: Hardened, gappy mastic around frames, sills and French or patio doors cut out and renewed to keep draughts and rain out.
• Commercial & hotel sealant: Sealant programmes for offices, hotels, care settings and schools, with early or late working where it helps.

• External & façade joints: Expansion joints in brick, render and cladding cut out and renewed at the right depth so they can move without splitting.
• New-build mastic & snagging: New-build bathrooms, kitchens and frames resealed where the original sealant has cracked as the house settles.
• Floor & skirting joints: Movement joints in tiled and concrete floors, and skirting gaps, sealed so they stay tidy and keep dirt out.
