Mastic and sealant work in Littlehampton
Littlehampton sits where the River Arun meets the sea, and homes here deal with weather from both. Mr Mastic is based in Crawley and covers Littlehampton, Wick, Lyminster and nearby Rustington, resealing baths, showers and kitchens and renewing window, door and external mastic.
Showers are the job we’re asked about most. A shower tray joint is under water every day, and once the seal opens even slightly, water tracks underneath and soaks into the floor or wall. Signs to look for are a soft tile, a stain on the ceiling below or a bead that has pulled away at one end. Our shower resealing page sets out how we take the old seal out, dry the joint and reseal it properly.
A harbour town with seafront terraces and post-war growth
Littlehampton was a fishing settlement long before it became a resort, and its population grew from under 600 in 1801 to nearly 6,000 by 1901. The seafront conservation area, with listed buildings on South Terrace, Western Road and Norfolk Place, keeps much of that 19th-century character. Many of these big houses now hold flats, and in a converted building one failed bath seal can reach several homes below it.
After the war, house building pushed north and absorbed Wick, Lyminster and Toddington, filling them with family houses, semis and bungalows. These homes have often had their bathrooms refitted more than once, and their uPVC windows are now old enough for the mastic to have hardened and split. By the river, old wharfside buildings have been turned into homes, such as the Riverside Wharf townhouses built inside Victorian warehouse shells.
Where frames meet brick, flint or cladding at odd angles, the sealant has to bridge gaps of different widths. We use backing rod where joints are deep and suitable sealants for each surface. Large glazed panels and roof lights are covered on our glazing sealant page.

River mouth weather on the Arun
Littlehampton faces straight out to the Channel, with the open beaches of East and West Beach either side of the Arun. Salt spray and wind-driven rain hit seafront and riverside frames hard, especially on south and west faces. Old mastic that has dried out cracks and lets water in behind sills and frames. We cut it out completely, check the joint beneath and reseal with a durable, flexible exterior sealant.
Seafront attractions, business parks and rental homes
The seafront and harbour bring visitors to Harbour Park, the East Beach Café and the town’s cafés, pubs and holiday lets, all of which have washrooms and kitchens that need sound, hygienic sealant. Toddington has a large business park, where offices and units need welfare rooms kept in good order. Out-of-hours working can be arranged for commercial jobs.
Littlehampton also has many rented flats and houses. Our guide to sealant for landlords explains why resealing between tenancies saves bigger repairs later.

Littlehampton: common questions
Do you cover Rustington and Wick?
Yes. We cover Littlehampton, Wick, Lyminster, Rustington and the surrounding area.
Water is getting under my shower tray. Can resealing fix it?
Often, yes, if the leak is through the seal. We remove the old sealant, dry the joint and reseal. If the tray itself is cracked, we’ll tell you.
My flat is in a converted seafront house. Can you seal the windows?
Where the frames can be reached safely, yes. For upper floors we’ll discuss access with you and the building’s owner or managing agent.
Can you reseal before I let my flat to a new tenant?
Yes. Between tenancies is ideal, as the sealant can cure without anyone using the bathroom.
Do you work at business units in Toddington?
Yes. We reseal staff kitchens, washrooms and external joints, and out-of-hours working can be arranged.
Can you seal over the old mastic to save time?
No. New sealant won’t bond properly to old, so we always remove it first.
How long after resealing can I use the shower?
Usually around 24 hours, depending on the product. We’ll tell you the cure time before we leave, and wiping the bead dry for the first few weeks helps it settle in.
