About our remedial sealant in Charlton
A movement joint stops working when its sealant splits or sets hard. The old sealant comes out and backing goes in to control the depth, then a flexible sealant matched to the movement goes in. We work on mouldy bath & shower sealant, expansion joints and shrunken worktop sealant, and people most often call us about smears and lumps from a botched reseal and black mould underneath the bead.
Somewhere as small as Charlton, 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.
Whatever the size of the job, it’s backed by our one-year guarantee in Charlton and across Surrey.

DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
FAQs for Charlton
Is Charlton 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 Charlton?
Yes, Charlton is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or email us and tell us what needs doing.
Can you strip sealant from an acrylic tray safely?
Yes. Residue is removed with a product suited to the surface rather than scraped hard.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint.
What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. Then phone 0345 464 0079 or drop us an email.
Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Do you work for letting agents?
Yes, regularly. Several properties can be quoted together, and between tenancies is a good time for the work.
Can you reseal a split movement joint?
Yes. Backing sets the depth and stops the sealant sticking to the back.
What we can’t put right
It helps to know what we can’t do:
- Sealant in an older building that needs testing for asbestos first
- A tray or bath that’s cracked
- Movement from fittings that are not supported
If in doubt, call 0345 464 0079 or send us an email and we will say what we think.
Joints and surfaces we work on
- Leaking tray & enclosure joints
- Failed movement joints
- Expansion joints
- Botched or over-sealed joints
- Shrunken worktop sealant
- Mouldy bath & shower sealant
For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Failed sealant is one of the commonest items on a check-out report. Several properties can go on one quote.
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Get the cause of a repeat leak found before resealing
- Do not add new sealant on top of old
- Report a tray that rocks or a worktop that lifts
- Clean sealant with mild products only
If the joint ever needs renewing, have it cut out, not sealed over. New silicone does not bond to old.
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.
How it works
All our tools and materials come with us in the van, 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. It normally takes a few hours, depending on how many layers have to come out. Somewhere as small as Charlton, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we find out how and where the joint has failed.
- Every layer of old sealant is cut and cleaned out.
- We clean the joint, treat any mould and let it dry.
- Moving joints get backing and a flexible sealant to suit.
- We tool the joint and tell you about anything else that needs attention.
Before we arrive
- Mention any leaks or damp you’ve noticed
- For business premises, tell us about site rules or sign-in
- Where the joints are inside, avoid wetting them before we arrive
Getting a quote
Asking for a quote is easy: let us know the job and the location and its rough size. Photos by email help us understand the job, and we will take it from there.

Why it’s worth doing now in Charlton
Hidden water does the most damage: wet floors, stained ceilings and swollen worktops. By comparison, sorting the joint is quick. Where a wall is exposed, as many are in small places like Charlton, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.

Remedial sealant in Charlton: local notes
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.
In the older streets around Church of St Mary Magdalene, walls and floors in older homes can move, and sealant and grout show it first. Letting a property close to Upper Halliford station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. For site and facilities teams at buildings such as Littleton CofE Infant School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
