How we handle remedial sealant in Itchen Stoke
In Itchen Stoke, as anywhere, remedial jobs tend to look alike: over-sealed joints, hidden mould, repeat leaks and split movement joints. We strip each one back and start from scratch. We work on expansion joints, leaking tray & enclosure joints and shrunken worktop sealant, and common reasons people get in touch are sealant peeling off a dusty or damp surface and dark patches showing through the sealant.
For a small place like Itchen Stoke, remedial sealant is planned like any other job: it just means planning the journey and access beforehand. Once we’re there, the bathroom or kitchen gets the same care as anywhere else.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

What remedial sealant looks like in Itchen Stoke
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.
Schools such as Perins School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Looking after it afterwards
Looking after new joints is easy:
- Check trays and worktops do not move
- Run the fan after every shower
- Keep an eye on the ceiling below the bathroom
- Use a soft cloth, not a scourer, on silicone
Don’t let anyone seal over it later. New silicone doesn’t bond to old.
Mould trapped under over-sealed joints spreads unseen. When it finally shows, the whole bead needs to come out.
What the job involves on each surface
Worktops & kitchens
Shrunken worktop sealant leaves a gap that lets water into the back edge. We strip it, degrease the joint and reseal colour-matched to the worktop.
Mouldy bath & shower sealant
Mould that has grown into silicone does not clean out for good. The sealant is cut out completely, the joint treated with a mould remover and dried before anti-fungal sanitary silicone goes in.
What happens if it’s left?
It’s easy to scratch acrylic, enamel or an uPVC frame cutting out old sealant, and any film left behind stops new sealant sticking. Careful stripping is where most of our time goes. Around Itchen Stoke, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Doing several joints on one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

How it works
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours for most joints, depending on how much old sealant has to come out. For a village or hamlet like Itchen Stoke, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- Surrounding tiles, trays and frames are protected first.
- The botched or failed sealant is cut away completely.
- We clean and degrease the joint and look for signs of movement or water.
- Once dry, a suitable sealant is applied and tooled.
- We give you the cure time and explain what caused the failure.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about parking restrictions

Do you need remedial sealant in Itchen Stoke?
How a joint is built matters as much as the product. A bead bonded on three sides, or laid too thick, can’t flex, so it tears when the joint moves. Backing rod or bond-breaker tape prevents it.
Keep an eye out for any of the following:
- A shower that leaks however often it’s resealed
- Thick, messy sealant smeared over tiles
- Torn expansion joints
- Sealant that came away because the surface wasn’t prepared
Homes close to St Mary's Church include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant.
