Bathroom & kitchen resealing in St Leonards, Hampshire
Our applicators work in St Leonards on bath, shower, basin, wet room, worktop and sink resealing. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Gaps where the bath or tray has moved
- New sealant laid over old sealant that is now lifting
- Black mould in the silicone that won’t clean off
How it works
All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. Most jobs take two to three hours for a typical bath, depending on how much old sealant there is. For a job in St Leonards, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We cover the area around the joints we’re working on.
- We cut away the old sealant and clean off what’s left.
- Mould is treated, then the joint is left to dry thoroughly.
- Any bath is filled with water, then we lay a bead of anti-fungal silicone in white, clear or a matching colour.
- We finish the joint, clear up and tell you how long to leave it before it gets wet.
Getting ready for the visit
- Tell us about any water getting in
- Keep children and pets away from the work area
- Try not to wet indoor joints just before the visit

Bathroom resealing in St Leonards
Kitchens need the same care as bathrooms. Worktop upstands, sink edges and splashback joints all take splashes every day, and water that gets into the back edge of a worktop can swell the board. Kitchen joints get a sealant suited to kitchens, colour-matched where it shows. Common call-outs are for mouldy sealant that has gone black and a joint torn by a bath that flexes, on sinks & splashbacks, shower trays & enclosures and baths.
In a smaller place like St Leonards, homes are mostly houses and bungalows rather than flats, from older cottages to newer builds. Sealant and grout wear out here just as they do in a big town.
We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

Bathrooms and kitchens in St Leonards
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
For an older house near a landmark such as All Saints, walls and floors in older homes can move, and sealant and grout show it first.

How the job changes by surface
Baths
A bath shifts slightly every time it’s filled, so we fill it with water before sealing. The joint is then laid with the bath at its lowest point and isn’t torn the first time it’s used.
Kitchen worktops & upstands
Water behind a laminate worktop can make the edge swell. A sound joint along the back edge stops that.

What else we do in St Leonards
Do you need bathroom resealing in St Leonards?
Black mould is behind a lot of resealing. Bathrooms without good ventilation give mould all the damp it needs, and mould that has grown into the silicone normally will not clean off.
The problems people normally mention when they call are:
- Damp behind the bath or under the tray
- Lumpy, uneven sealant from a DIY attempt
- Sealant that has split, shrunk or peeled away
- Failed sealant on the screen profile
For site and facilities teams at buildings such as St Ives Primary & Nursery School, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.

Why act early in St Leonards
A clean new bead makes a room look cared for, which helps when a home is being let or put on the market. A smeared, uneven DIY bead does the opposite. Homes in smaller places like St Leonards can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.

Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Wipe the sealant dry after showering
- Move toiletries away from the joint
- Keep the fan on for a while after bathing
- Let new sealant cure fully before it gets wet
Keep bottles and razors off the sealant line, as they hold water against it. Squeegeeing the walls and tray after use helps the joint dry.
Don’t wait for a refit to deal with failed sealant. Like paintwork, sealant needs renewing from time to time, and renewing it as soon as it fails protects everything around it.
