Resealing and mastic work across New Romney
New Romney is the main town of Romney Marsh, a small, old town with a busy High Street, set on flat land more than a mile back from the sea, with Littlestone and Greatstone along the coast beside it. Around 7,000 people live here. Mr Mastic covers New Romney and the surrounding Marsh from our base in Crawley, resealing baths, showers and kitchens and renewing window and door mastic.
Down here, a good reseal has to cope with salt air on the coast and with older buildings in the town that have moved over the centuries. We remove the old sealant completely, clean and dry the joint, and choose a product for the job rather than using one tube for everything. Our guide on looking after new sealant explains how to keep it in good shape afterwards.
Medieval houses, an old town hall and coastal homes
New Romney was once a harbour town, but storms in the 13th century, including the great storm of 1287, filled the harbour with sand and silt and left the town stranded inland. That is why several old buildings have steps leading down from the pavement. The town keeps a remarkable group of old buildings: the Norman church of St Nicholas, the Town Hall of 1702, the West Street almshouses founded in 1610 and rebuilt in 1734, and houses in West Street that date from the early 14th century.
Old buildings like these are rarely square or still. Window frames sit in openings that have shifted, and bathrooms have been added into rooms never designed for them. A rigid sealant will not last; a flexible one, and on painted timber a paintable one, will. We take care not to damage old surfaces when cutting out failed mastic.
Beyond the centre, much of the housing is 20th-century, and along the coast at Littlestone and Greatstone the homes face the full sea weather. Their uPVC windows and patio doors take sun, wind and salt, and the mastic round them hardens and splits sooner than it would inland.

Flat marshland, shingle and sea wind
Romney Marsh is open, flat land reclaimed from the sea, and there is little shelter from the wind. Along the coast the beach changes from heavier stones at Greatstone to finer shingle at Littlestone and sand towards St Mary’s Bay, and salt carried on the wind reaches homes well back from the front. External joints on south- and west-facing walls take the most punishment.
We use flexible weatherproof sealants outside, with backing rod where the gap is deep, so the joint can move with the frame. On single-storey homes, most external work is quick, as frames can usually be reached from the ground. For older High Street buildings with flats above shops, we can agree access and parking with the owner before we arrive.
High Street businesses, holiday homes and schools
The High Street has independent shops, cafés, bars and restaurants, many in historic buildings with small kitchens and washrooms tucked behind the shopfront. We can reseal sinks, worktops and toilets before opening or after closing. The Marsh Academy, the area’s secondary school, and the Romney, Hythe and Dymchurch Railway station on the eastern edge of town are among the larger buildings.
The coast nearby has holiday homes and lets that see heavy summer use. Our page on sealant for hotels and guest accommodation explains how we work around bookings.

What we do in New Romney
- Bathroom & kitchen resealing: Every joint in the bathroom and kitchen, from the bath edge to the worktop, stripped back and resealed with anti-fungal silicone.
- 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.
- Commercial & hotel sealant: Commercial washrooms, kitchens and wet areas resealed floor by floor, so only a few rooms are out of use at once.
- Remedial sealant & repairs: Messy, layered or wrong-product sealant cut out and replaced with the right sealant, laid the right way.
- Fire-rated sealant: Fire-rated sealant for service penetrations and frame gaps where it has been specified, applied to the tested details.
- 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: Floor and skirting joints in homes, shops and warehouses sealed neatly and to the right depth.
- Regrouting: Tired or mouldy grout raked out and renewed, and the internal corners finished in flexible silicone.
- Glazing & conservatory sealant: Leaking conservatory and rooflight joints, glass panels and shower screens resealed with silicone made for glass.
- Gutter, fascia & soffit sealing: Gutter unions, outlets and fascia joints that leak in heavy rain cleaned and resealed.
- Sand mastic for sash & case windows: Sash and case window surrounds in stone and brick re-pointed with traditional sand mastic.

Questions we’re asked in New Romney
Do you cover all of New Romney?
Yes. We cover the town and the coast beside it, including Littlestone, Greatstone and St Mary’s Bay, and villages across Romney Marsh.
My house in the old town is centuries old. Will modern sealant suit it?
Yes, if it is chosen carefully. We use flexible products for joints that move and paintable sealants where a timber frame needs painting.
The mastic on my Greatstone house keeps cracking. Why?
Sun, wind and salt dry out external sealant quickly on the coast. We cut out the old bead and use a flexible weatherproof sealant set at the right depth.
Can you reseal my holiday let before the summer season?
Yes. Book in before the first guests arrive and the sealant will have plenty of time to cure.
Do you work for shops and cafés on the High Street?
Yes. We can work before opening or after closing so you do not lose trading time.
Can you remove old silicone without damaging tiles?
Yes. We cut and scrape old sealant out carefully and use a remover for the last traces, so tiles and enamel are not scratched.
How long does it take you to get to New Romney?
It is a longer trip from Crawley, so we book visits in advance. Call us and we will give you a date.
