Remedial sealant in Cheam
A joint that keeps letting you down needs more than another bead. It helps to have pictures when you call 0345 464 0079 or drop us an email, and say how long ago it was last done. If you are dealing with mould trapped under a layer of silicone and over-sealed joints coming away, we can help, whatever the surface.
London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. For a bathroom or kitchen in Cheam, getting the joints right keeps water where it belongs and the room looking clean.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Leave it or put it right?
Stripping out botched sealant adds time to a reseal, but not by much: it takes a few hours for most joints, depending on how much old sealant has to come out. It’s far less disruption than resealing the same joint again and again. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler for homes in Cheam.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Why book with us
- Homes, businesses and hotels
- A choice of colours where the product allows

Your questions about remedial sealant in Cheam
Could a tired shower seal in my Cheam flat affect the neighbours below?
It can, yes: water that gets past a split bead or cracked grout often runs under the tray and shows on the ceiling below. It’s far simpler to replace tired sealant early than to deal with a neighbour’s ceiling.
Is parking a problem for a job in Cheam?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
How long does remedial resealing take?
It takes a few hours for most joints, depending on how much old sealant has to come out. We’ll give you a timescale when we quote.
Do you work in Cheam?
Yes. We work in Cheam and the rest of Greater London. To book, phone 0345 464 0079 or drop us an email.
Can you take off two layers of silicone?
Yes. We remove every layer; new silicone does not bond to old silicone, which is why over-sealing fails.
Do I need to be at home?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that generally means someone at home.
How the job changes by surface
Worktops & kitchens
Old kitchen sealant pulls back from the wall over time. It’s cut out, degreased and resealed colour-matched to the worktop.
Mouldy bath & shower sealant
Black mould inside the bead won’t scrub out. All of it comes out, and the joint is treated and dried before anti-fungal sanitary silicone goes in.
What sealant work cannot fix
New sealant can’t fix everything, and we will tell you before we start. It won’t solve:
- A tray or bath that is cracked
- Movement from fittings that are not supported
- Water damage behind tiles that needs a tiler
If you are not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.
Surfaces we seal
- Expansion joints
- Mouldy bath & shower sealant
- Failed movement joints
- Leaking tray & enclosure joints
- Botched or over-sealed joints
- Shrunken worktop sealant
Signs you need remedial sealant in Cheam
All sealant wears out eventually. Mould grows into the silicone, the surface hardens and the bead shrinks, faster where ventilation is poor. At that point it has to come out.
People usually contact us when they notice one of these:
- Floor or wall movement joints that have failed
- Worktop sealant that has shrunk and split
- A shower that leaks however often it’s resealed
- Mould trapped under a layer of silicone
For an older house near a landmark such as Church of St Andrew, walls and floors in older homes can move, and sealant and grout show it first.
Questions to ask before booking
- Whether they’re fully insured
- How the joint is cleaned and prepared
- How long the guarantee is
- When the joint can take water or movement
For landlords and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Bathrooms and kitchens in Cheam
London’s water is hard, which leaves limescale on sealant, grout and taps. In a London flat, water from a failed bath or shower seal can reach the neighbours below, so tired sealant is best dealt with early.
For landlords with property near Cheam station, a joint that keeps failing is best fixed properly while the property is empty. As a London address, Cheam can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

How it works
We keep the work tidy and contained to the area we’re working on, so you can carry on as normal. The job generally takes a few hours for a typical bath or shower, longer where several layers have been applied. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- First we find out how and where the joint has failed.
- All the old sealant comes out, including any layers underneath.
- The joint is cleaned, treated for mould and left to dry.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- We tool the joint and tell you about anything else that needs attention.
How to prepare
- For business premises, tell us about site rules or sign-in
- Clear items away from the joints we’re working on
- Keep children and pets away from the work area
