Mastic man in Rochester

Mastic and sealant work in Rochester

Rochester mixes some of the oldest buildings in Kent with brand-new streets beside the river, and both need sealant done properly. Mr Mastic travels from our Crawley base to cover Rochester, Strood, Borstal and the rest of the town, resealing bathrooms and kitchens, renewing window and door mastic and putting right joints that have let water in.

In older properties, the right product matters as much as a neat finish. Where a joint meets painted joinery or render, standard silicone isn’t always the answer, and we’ll explain the options before we start. Indoors, we can match the sealant to your bath, tiles or worktop with colour-matched resealing, so the bead blends in rather than standing out.

Timber frames, Georgian sashes and riverside new builds

The Historic Rochester Conservation Area, first designated in 1972, takes in the High Street, the castle and cathedral precinct, the Esplanade and streets such as St Margaret’s Street and The Vines. Medway Council’s appraisal describes timber-framed buildings from before 1500, some weatherboarded or covered in lime render, Georgian houses with painted softwood sash windows, and Victorian villas and semis. Joints between old timber, soft brick and lime render move differently, so the sealant has to stay flexible and must not trap moisture in the wall. Around painted sashes, a paintable sealant often makes more sense than silicone.

Many of these buildings combine a shop at street level with living space above, and their bathrooms are often squeezed into awkward corners. Short runs of sealant, odd angles and old floors that move all need careful work.

North of the railway, Rochester Riverside has turned former brownfield land into a new neighbourhood of around 1,400 homes, with the ground raised above flood levels. New builds like these settle as they dry out, and shower trays and bath edges often show cracked sealant within the first couple of years. Our new build mastic page explains what we check and replace.

Jobs we take on in Rochester

• 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.
• 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: Leaks and lifting beads from earlier sealant jobs put right, starting with finding out why they failed.
• 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: Early-failing sealant in new homes fixed properly, plus mastic packages and snagging for developers.
• Floor & skirting joints: Skirting-to-floor gaps, tiled floor movement joints and concrete floor joints sealed with the right product.
• Regrouting: Cracked, stained or crumbling grout raked out and replaced, with corners resealed in 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: Traditional sand mastic for period windows and doors where a modern sealant would look out of place.
