Bathroom Resealing in Swanscombe
Our applicators work in Swanscombe on bath, shower, basin, wet room, worktop and sink resealing. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.

- A messy, uneven bead from a previous reseal
- Damp behind the bath or under the tray
Bathroom resealing for homes and businesses in Swanscombe
Kitchens need the same care as bathrooms. Worktop upstands, sink edges and splashback joints get wet every single day, and water that gets into the back edge of a worktop can swell the board. We reseal them with a kitchen-suitable silicone, matched to the worktop where it’s on show. If you have leaking joints on a shower screen and black spots spreading through the bead, we can help.
Homes around Swanscombe range from older cottages to more recent houses. In older homes, walls and floors can move a little more, so the right flexible sealant matters.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

What happens if it’s left?
Leaving a split or mouldy bead only stores up trouble. Once water is behind the bath, it can reach floorboards, panels and the ceiling underneath, turning a small job into a building repair. In a smaller place like Swanscombe, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll give you a clear price for the lot.

Common problems we fix in Swanscombe
Sealing over old silicone is one of the commonest mistakes we find. Fresh silicone can’t grip the old bead underneath, so it peels, leaks and hides mould behind it.
It’s worth asking for a quote if you see:
- Water getting behind the bath panel
- Gaps between the worktop and the wall
- Splits where the tray meets the wall
- Water escaping at the shower enclosure
For site and facilities teams at buildings such as Knockhall Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

What happens on the day
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes two to three hours for a typical bath, depending on how much old sealant there is. For a job in Swanscombe, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, each joint is checked for movement and signs of water.
- Every trace of the old bead is removed, including the thin smear on the tiles.
- The joint is cleaned, degreased and treated for mould.
- With the joint dry, and any bath loaded with water, a single bead of anti-fungal silicone is applied.
- The bead is tooled smooth and you’re told the cure time, usually around 24 hours.
How to prepare
- Clear items away from the joints we’re working on
- Mention any sign-in or site rules at work premises
- Let us know about earlier repairs to the joints

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Bathrooms and kitchens in Swanscombe
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
Rented homes near Greenhithe for Bluewater station change hands often, and fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay. In the older streets around Church of St Mary, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

What the job involves on each surface
Basins & vanity units
Vanity units have long, worktop-style joints against the wall. Water that gets behind can damage the unit, so a neat, continuous bead matters.
Sinks & splashbacks
The edge of an inset sink is a common place for water to get under the worktop. We reseal the visible edge of the sink where it has failed.

How to look after the new joints
A little care helps the new joints last. Our advice:
- Dry worktop joints after washing up
- Never pick at the silicone with a blade
- Wipe the sealant dry after showering
- Look for lifting corners and small gaps now and then
Give the silicone time to cure before it gets wet, following the cure time we give you. After that, a quick wipe after showering helps keep it clean.
A split bead lets water through every time the bath or shower is used. Over time that water reaches floors, walls and ceilings. Resealing early stops it.
