About our bathroom resealing in Itchen
A bead that has gone black, split or come away shouldn’t be left until there’s a leak. Just call 0345 464 0079 or drop us an email with a photo of the joints, and we’ll give you a clear price before any work starts. If you are dealing with shrunken sealant along the back of a worktop and water getting behind the bath panel, we can help.
In and around Itchen, older properties sit alongside newer ones. In older homes, walls and floors can move a little more, so the right flexible sealant matters.
We stand behind the work with a one-year guarantee.

The process
We bring everything the job needs with us. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take around two hours for one bath or shower, longer for a whole bathroom. Parking around Itchen is usually easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- First the area is protected and every bit of old sealant removed.
- Next, the joint is cleaned and any mould is treated.
- Once it’s dry, any bath is filled so the bead is laid with it at its heaviest.
- A single bead of anti-fungal sanitary silicone is applied and tooled smooth.
- Finally we tidy up and explain the cure time before we leave.
How to prepare
- Mention any leaks or damp you’ve noticed
- Move anything stored near the joints
- Keep pets and children clear of the area while we work

Related advice
DIY versus a professional finish
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, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Don’t let bottles sit on the bead
- Use gentle cleaners on the silicone
- Wipe up water along the back of the worktop
- Open a window or run the fan so the room dries
In a kitchen, don’t let water sit along the back of the worktop. A dry joint lasts longer.
There’s no need to wait for a full refurbishment. Sealant is a maintenance item, like the paint on a window frame, and replacing it when it fails protects the rest of the room.

Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Loose or hollow tiles, or failed tanking behind them
- Cracked or missing grout between tiles (that is regrouting)
- A cracked shower tray or bath (that needs repair or replacement)
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.

Why it’s worth doing now in Itchen
Sorting it now is quick: it takes a couple of hours for one bath or shower, or most of a day for a full bathroom and kitchen. Wait for a leak and you may be looking at panels off, drying out and redecorating too. Homes in smaller places like Itchen can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
The cost depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before work begins, so you know where you stand.
Why book with us
- A choice of colours where the product allows
- Anti-fungal silicone where joints get wet
- Full insurance on every job
- A sealant colour to suit the surroundings

Bathrooms and kitchens in Itchen
Itchen is close to the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, and sealant and grout that work that hard wear out sooner. There are hotels and other places to stay in and around Itchen. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.
Schools such as Ludlow Junior 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. Letting a property close to Woolston station? Then mouldy sealant is one of the first things a new tenant notices, so it’s worth renewing between lets. If you live in an older home near Jesus Chapel - St Mary Extra, older homes can move a little, which is hard on rigid grout and tired sealant.
