South Norwood Remedial Sealant
Remedial sealant for South Norwood and the surrounding area: careful preparation, the right product and tidy work. Ask us for a quick quote.
- Kitchen joints letting water behind the worktop
- Sealant that came away because the surface wasn’t prepared
- Repeat leaks from the same joint
Looking after it afterwards
After the cure time, these simple habits help:
- Do not point over movement joints
- Find out why the sealant failed first
- Act on a lifting corner right away
- Air the bathroom so the sealant can dry
Give the new sealant its full cure time: follow the cure time we give you.
A failing joint rarely gets better on its own. Every shower or downpour sends more water through, into floors, walls or ceilings. Early action keeps it to a sealant job.
Remedial sealant for homes and businesses in South Norwood
Movement and expansion joints fail when the sealant cannot stretch. We cut out the failed sealant and set the depth with backing, then a flexible sealant matched to the movement goes in. If you’re dealing with caulk or the wrong sealant used in a wet area and leaks that keep coming back after resealing, we can put it right, on failed movement joints, leaking tray & enclosure joints and expansion joints alike.
London homes include a lot of flats, conversions and mansion blocks, and many bathrooms sit right above someone else’s ceiling. In South Norwood, that is a good reason to put tired sealant and grout right early.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Honest limits
New sealant can’t fix everything, and we’d rather say so up front. It won’t solve:
- Water damage behind tiles that needs a tiler
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- A cracked shower tray or bath (that needs repair or replacing)
If you’re not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer before booking.
Surfaces we seal
- Failed movement joints
- Mouldy bath & shower sealant
- Shrunken worktop sealant
- Leaking tray & enclosure joints
- Botched or over-sealed joints

Quotes for remedial sealant in South Norwood
There’s no set price list. The quote depends on:
- The number and length of the joints
- Whether the work is at height
- Whether there’s mould to deal with
- How much old sealant there is and how hard it is to remove
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, call 0345 464 0079 or email us and we will give you an honest view and a quote.

South Norwood: your questions answered
Do you work for hotels and guest houses in South Norwood?
Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.
I let a flat near Norwood Junction station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
How long before the joint can be used?
It depends on the product. We tell you how long to leave it before we go.
Do you offer different sealant colours?
We help you choose a colour that suits. The product needed can limit the range.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Where do you work from?
We’re a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Can I add another job to the visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Do you need remedial sealant in South Norwood?
Silicone only bonds to surfaces that are clean and dry. Soap film, dust, damp or old residue stop it gripping, and the joint starts to come away early.
The most common problems we see are:
- Floor or wall movement joints that have failed
- Caulk or the wrong sealant used in a wet area
- A second bead peeling off the first
- Dark patches showing through the sealant
For an older house near a landmark such as Church of St Mark, walls and floors in older homes can move, and sealant and grout show it first.
Before you book anyone
- Whether they’re fully insured
- How hidden problems are handled
- Whether they seal over old material or remove it
- How much experience the applicator has
How the visit works
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes a few hours for a typical bath or shower, longer where several layers have been applied, including the tidy-up. In South Norwood, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Each layer is cut out and the residue cleaned off.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Clear the area around the work
- Mention any parking rules near the property
