About our bathroom resealing in Clayhall
Kitchens need the same care as bathrooms. Worktop upstands, sink edges and splashback joints all take splashes every day, and water behind a laminate worktop can make it swell. We reseal them with a kitchen-suitable silicone, matched to the worktop where it’s on show. Typical jobs include a reseal done over the top of the old bead and leaks into the floor or ceiling below, on kitchen worktops & upstands, shower trays & enclosures and sinks & splashbacks.
In a smaller place like Clayhall, homes are mostly houses and bungalows rather than flats, from older cottages to newer builds. Bathrooms and kitchens here get the same daily wear as anywhere, and the sealant and grout show it first.
Each job carries a 12-month guarantee, large or small.

Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Common questions in Clayhall
Will you come out to Clayhall?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Portsmouth Harbour station?

Is white the only colour available?
There’s a choice: clear, white and colours chosen to suit the room. We’ll talk it through when we quote.
Do I need to be at home?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.

Different surfaces, different methods
Baths
Baths move more than any other fitting, so it’s filled with water before the bead goes on. The joint is then laid with the bath at its lowest point.
Sinks & splashbacks
Next to the sink, the sealant has to cope with constant water, including a food-safe sealant where that is needed. The joint is laid neatly so it’s easy to wipe.
What we do, step by step
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the job takes two to three hours for a typical bath, depending on how much old sealant there is in most cases. For a job in Clayhall, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- Protection goes down around the bath, shower or worktop.
- We cut away the old sealant and clean off what’s left.
- We treat any mould and let the joint dry properly.
- 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.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Where the joints are inside, avoid wetting them before we arrive
- Mention any leaks or damp you’ve noticed

Bathroom resealing in Clayhall: local notes
Clayhall is within about 1 mile of the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, which wears sealant and grout out faster than in a quiet home. Most of the South East has hard water, 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 St Francis, walls and floors in older homes can move, and sealant and grout show it first. For landlords with property near Portsmouth Harbour station, a reseal between tenants is a quick way to make the bathroom and kitchen look cared for.
Clayhall is about 2 miles south-east of Gosport, in Hampshire. Anywhere in PO12, our applicators can take on bathroom resealing. We cover 683 towns and villages across Hampshire.

When something else is needed
Sealant isn’t the answer to every problem, and we’d rather say so up front. It will not solve:
- Cracks in the tray itself rather than the joint
- Water getting in through the grout rather than the sealant
- A tray that rocks until it’s re-bedded
If in doubt, ring 0345 464 0079 or email us and we will say what we think.

Why act early in Clayhall
Dealing with sealant early is a short job: it takes half a day or less for one room, longer when the kitchen is included. Wait for a leak and you may be looking at panels off, drying out and redecorating too. Homes in smaller places like Clayhall 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.

When to call us in Clayhall
Baths and trays move. An acrylic bath flexes under load, while a poorly supported tray can shift underfoot. That movement works at the bead until it splits or peels away.
Any of these means the joints need attention:
- Black spots spreading through the bead
- A messy, uneven bead from a previous reseal
- A bead that has pulled away from the tiles
- New sealant laid over old sealant that is now lifting
Schools such as Haselworth Primary School are buildings too, and 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.
