Your local mastic man for Shoreham-by-Sea

Shoreham-by-Sea stands at the mouth of the River Adur, with the town on the north bank and Shoreham Beach on the shingle spit across the water. It is a working harbour town as well as a place to live, and the sea is never far from any front door. Mr Mastic is based in Crawley and covers Shoreham for bath and shower resealing, kitchen sealant, window and door mastic and external joints.

Coastal homes get through sealant faster than inland ones, especially outside. We cut out every trace of the failed bead, clean and dry the joint, and pick a product for where it is going, whether that is a shower tray in a flat or a frame facing the Channel. Our guide to how long silicone sealant lasts explains what wears it out.

A medieval street grid, a shingle spit and Old Shoreham

The town centre was laid out on a grid around the early 1100s, and that grid still shapes the streets around St Mary de Haura church today. Older terraced houses and cottages sit close together here, many with bathrooms fitted into small rooms at the back. To the north, Old Shoreham gathers around its Norman church of St Nicolas, and to the east lies Kingston Buci, with more family housing between them.

Shoreham Beach has an unusual story. Around 1900, old railway carriages were turned into summer homes, and the area became known as Bungalow Town. Much of that housing was cleared for defence in the Second World War, and most of what survived was replaced by modern houses. Today the beach is a neighbourhood of newer homes, linked to the town centre by the Adur Ferry Bridge, which opened in 2013.

Each part of town has its own sealant jobs. Older terraces need flexible beads where timber floors move under a bath. Newer houses and flats on the beach often have large glazed doors and balconies, and the joints around them face salt wind every day. Along the river, houseboats converted from barges and tugs sit on the mud flats; if you live on one, call us to talk through what you need.

Salt wind, river edges and flats

The most exposed homes in Shoreham are on the beach and along the river, where wind carries salt and rain straight at the walls. External mastic on those faces dries out and lets go sooner than on a sheltered street. We cut out cracked joints, use backing rod where the gap is deep and finish with weatherproof sealant designed to move. Our window and door mastic page lists the frame types we work on.

Shoreham also has a good number of flats, and a failed shower seal in a flat usually shows up first on the ceiling below. We can arrange access and timings with you or your managing agent, and we bring everything up ourselves so we are not going back and forth to the van.

Harbour businesses, offices and the airport

Shoreham Harbour is still in commercial use, with businesses and industrial units along the waterfront. Ricardo, the engineering consultancy, has its main offices in the town, and Shoreham Airport, west of the centre, has a Grade II* listed Art Deco terminal from 1936. Offices, workshops and units like these all have kitchens, toilets and washrooms that need resealing from time to time, and we can work out of hours for commercial clients.

We also reseal cafés, shops and rented flats in the town centre, often between tenancies for local landlords.

What we do in Shoreham-by-Sea

  • Bathroom & kitchen resealing: Bathroom and kitchen joints taken back to a clean, dry surface and finished with fresh anti-fungal silicone that won’t lift.
  • Window & door mastic: Window and door mastic that has dried out in the sun replaced with a weather-resistant joint that can move with the frame.

Questions we’re asked in Shoreham-by-Sea

Do you cover all of Shoreham-by-Sea?

Yes. We cover the town centre, Shoreham Beach, Old Shoreham and Kingston Buci, plus Southwick next door and the villages up the Adur valley.

Why does the mastic on my Shoreham Beach home fail so quickly?

Salt wind, sun and rain all work on external sealant there. Cutting out old mastic and using a flexible weatherproof sealant gives the joint a better life.

Can you reseal a shower in a flat without disturbing the neighbours?

Yes. The work is quiet, and we can agree access and timing with you or your managing agent.

Do you work on offices and units near the harbour?

Yes. We reseal staff kitchens, toilets and washrooms, and out-of-hours working can be arranged.

My balcony door sealant has gone grey and cracked. Can it be replaced?

Yes. We cut it out, clean the frame and surrounding surface, and reseal with a weatherproof product in a colour to match.

Can you seal over the old silicone to save time?

No. New silicone will not bond properly to old, so we always remove it first.

Is the work guaranteed?

Yes. Every job comes with our one-year guarantee.
