Your local mastic man for Eastbourne

A grey, cracked bead round the bath or a seaside window frame that rattles with every gust is usually the moment people start looking for a mastic man in Eastbourne. Mr Mastic is based in Crawley and covers Eastbourne as part of our regular East Sussex round. We reseal baths, showers, basins and kitchen worktops, cut out and renew mastic around windows and doors, and seal the outside joints that keep wind-driven rain off the brickwork and render.

The method never changes, whatever the property. Every trace of the old sealant comes out first, because fresh silicone will not grip old silicone. The joint is cleaned, treated where mould has taken hold and left dry before a single, even bead goes on. It takes a little longer than smearing new sealant over the old, but it is the difference between a joint that lasts years and one that lets you down within weeks.

Victorian seafront, post-war estates and a modern marina

Eastbourne’s character comes from the Victorian resort laid out for the 7th Duke of Devonshire, with architect Henry Currey planning much of the new town from 1859. The seafront is lined with Victorian hotels and tall stucco and brick buildings, and the Town Centre and Seafront and Meads conservation areas protect a great deal of that period stock. Many of the big houses are now flats. Tall sash and bay windows, deep sills and stucco joints all depend on mastic that can move as old timber and masonry shift through the year.

Inland, the picture changes. The Old Town grew from the medieval village of Bourne, and after the Second World War housing estates were built at Hampden Park, Willingdon Trees and Langney. Bathrooms in these homes have often been refitted several times, so we regularly find two or three generations of sealant stacked on top of one another, or a bath that has dropped slightly and torn its seal.

At the eastern edge, Sovereign Harbour was built on the old Crumbles shingle bank from the 1990s and now has more than 3,000 homes around its marina. Houses and flats here are newer, but their sealant is reaching the age where it splits, discolours and lets water behind shower trays and around balcony doors. Our guide to how long silicone sealant lasts explains what to look for.

Sunshine and sea wind

Eastbourne is one of the sunniest places in Britain, which is tough on external mastic. Ultraviolet light dries sealant out, and south-facing frames that look over the sea take the worst of it, alongside salt-laden wind off the Channel. Hardened mastic cannot stretch as frames expand in the heat, so it cracks and peels. Outside, we use flexible, weatherproof sealant at the right depth, with backing rod in wider gaps. Our external joint sealing page covers the detail.

Seafront hotels, care homes and rented flats

Hotels are part of Eastbourne’s identity, from the Grand Hotel on the seafront to smaller guest houses in the side streets. Busy guest bathrooms wear out sealant fast, and a black line round a bath is the sort of thing that ends up in an online review. We can work room by room so the rest of the building keeps trading; see our page for sealant contractors for hotels.

The town also has many care homes, retirement flats and rented properties, as well as larger sites such as Eastbourne District General Hospital and its surrounding services. We work for landlords, managing agents and care providers, and quote clearly for a single room or a whole building.

Questions we’re asked in Eastbourne

Do you cover all of Eastbourne?

Yes. We cover the whole town, including Meads, the Old Town, Hampden Park, Langney, Willingdon and Sovereign Harbour, travelling from our base in Crawley.

My sea-facing windows are in a conservation area. Can you reseal them?

Yes. We cut out the old mastic and choose a sealant and colour to suit the frame and wall. For timber that needs painting, we can suggest a paintable sealant.

Why does the mastic on my south-facing frames keep cracking?

Eastbourne’s strong sunshine dries out and hardens sealant, so it can no longer move with the frame. Replacing it with a flexible, UV-resistant product gives a longer life.

I live in Sovereign Harbour. Is it normal for the shower seal to fail?

Yes, sealant in newer homes often splits as the building settles and the shower gets daily use. We remove it fully and reseal with anti-fungal silicone.

Can you reseal hotel bathrooms without closing the whole hotel?

Yes. We work room by room so rooms go back into use once the sealant has cured, and out-of-hours working can be arranged.

Do you work in care homes and retirement flats?

Yes. We plan the work around residents and staff, and can quote for one bathroom or a full refresh of the building.

How long before I can use the bath again?

Usually around 24 hours. We will tell you the cure time for the product we have used before we leave.
