Southfleet Remedial Sealant
We cover Southfleet for removing failed, mouldy or leaking sealant and putting it right. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Sealant peeling off a dusty or damp surface
- Sealant applied over old sealant that has lifted
- Caulk or the wrong sealant used in a wet area
What we do, step by step
We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for most joints, depending on how much old sealant has to come out. For a village or hamlet like Southfleet, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking the joint for movement, leaks and the reason it failed.
- All the old sealant comes out, including any layers underneath.
- The joint is cleaned, treated for mould and left to dry.
- We use the right backing and sealant for any joint that moves.
- We tool the joint and tell you about anything else that needs attention.
Before we arrive
- Let us know about parking restrictions
- On commercial sites, let us know about site rules
- Try not to wet indoor joints just before the visit

Remedial sealant in Southfleet, done properly
The wrong product in the wrong joint won’t last, however tidy it looks. Out it comes, and in goes a sealant suited to the job. We work on expansion joints, mouldy bath & shower sealant and failed movement joints, and the jobs we see most are dark patches showing through the sealant and movement joints that have split or pulled away.
Somewhere as small as Southfleet, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Movement in older walls and floors tends to show first as cracked grout or split sealant.
We stand behind the work with a one-year guarantee.

What else we do in Southfleet
Looking after it afterwards
So the new joints stay in good condition:
- Do not point over movement joints
- Deal with small splits early
- Check ceilings under showers for marks
- Check trays and worktops do not move
Ventilation keeps mould away from the new bead: use the extractor or open a window after showering.
Warning signs: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Each one is worth getting looked at.
Bathrooms and kitchens in Southfleet
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
Rented homes near Longfield station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. Managing a site like Sedley's Church of England Voluntary Aided Primary School? Then 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.

Questions from Southfleet
Is Southfleet within the area you cover?
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 do remedial sealant in Southfleet?
Yes, Southfleet is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or email us and tell us what needs doing.
Can failed expansion joints be resealed?
Yes. If a joint has been filled with mortar or rigid filler, we rake it out where possible, then the joint is sealed properly.
How long will it take to strip and reseal the joint?
Allow a few hours, depending on how many layers have to come out. We’ll give you a timescale when we quote.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Do you guarantee remedial jobs?
Yes. Our one-year guarantee covers the work, and we are ARBOMaster approved.
Can you remove old sealant without damaging the bath?
Yes. Residue is removed with a product suited to the surface rather than scraped hard.
Can you fix a reseal that hasn’t worked?
Yes. We check it’s the sealant and not the tray, valve or waste, then the joints are stripped and resealed.
How we quote for remedial sealant
You’ll get a clear quote before work begins. It takes into account:
- The type of sealant required
- The old material and how stubborn it is
- Access and height
- When we can work, for business premises
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Helping us quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- A few pictures by email, if you can
- Whether it has been sealed before
- Any access issues, like height or stairs
- The rough size of the job
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. Whenever you are ready, ring 0345 464 0079 or send us an email.
Do you need remedial sealant in Southfleet?
Movement tears sealant that isn’t designed for it. A bath that flexes, a tray that rocks or a building joint that opens and closes split any bead that’s too stiff or too thin.
People usually contact us after spotting one of these:
- Sealant applied over old sealant that has lifted
- Smears and lumps from a botched reseal
- A shower that leaks however often it’s resealed
- Black mould underneath the bead
For an older house near a landmark such as Church of St Nicholas, walls and floors in older homes can move, and sealant and grout show it first.
What to look for in a quote
- How long the guarantee is
- Which colour the sealant will be
- How much experience the applicator has
- What the quote includes, VAT included or not
Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
When something else is needed
New sealant cannot fix everything, and we will tell you before work begins. Sealant won’t put right:
- Plumbing leaks behind walls or under trays
- Cracks in the fitting rather than the joint
- Movement from fittings that aren’t supported
If you are not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
