About our remedial sealant in Southwark
Removing failed sealant is the hardest part of the job. Every layer is cut out, the residue cleaned off and the joint degreased, taking care not to scratch the surfaces around it. New sealant only bonds to a clean, dry joint. We work on leaking tray & enclosure joints, botched or over-sealed joints and expansion joints, and people most often call us about worktop sealant that has shrunk and split and products that weren’t meant for the joint.
In much of London, period terraces have been converted into flats over the years, with bathrooms fitted into whatever space was available. Small, steamy rooms are where mould gets into sealant and grout fastest.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

How the job changes by surface
Over-sealed & botched joints
Thick, smeared sealant looks messy and hides problems. Taking it back shows what’s underneath.
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 ahead of a new anti-fungal bead.
What happens if it’s left?
It’s easy to scratch acrylic, enamel or an uPVC frame cutting out old sealant, and the residue left behind stops the next bead bonding. Careful removal is most of a remedial job. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble.
Doing several joints on one visit normally makes better use of the time than several visits. You will get one clear quote for the whole job.

Signs you need remedial sealant in Southwark
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.
It’s worth asking for a quote if you see:
- Smears and lumps from a botched reseal
- Worktop sealant that has shrunk and split
- Decorators’ caulk around a bath or shower
- Dark patches showing through the sealant
Homes close to Borough Welsh Congregational Chapel include some older properties, and bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

Aftercare tips
So the new joints stay in good condition:
- Find out why the sealant failed first
- Act on a lifting corner straight away
- Never fill a movement joint with mortar or grout
- Clean sealant with mild products only
Keep an eye on the joint at first, particularly where the original failure was caused by movement. Should anything change, call 0345 464 0079 or send us an email.
Signs to act on: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Each one is worth getting looked at.
Remedial sealant in Southwark: local notes
London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, which is why it’s worth fixing early. London has hard water, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in.
For landlords with property near Elephant & Castle station, a joint that keeps failing is best fixed properly while the property is empty. Managing a site like Charles Dickens Primary School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

What we do, step by step
We keep the work tidy and contained to the area we’re working on. The job generally takes a few hours for most joints, depending on how much old sealant has to come out. For a job in Southwark, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- We start by checking the joint for movement, leaks and the reason it failed.
- We strip the joint completely, removing any layers below.
- Next, any mould is treated and the joint dried.
- 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
- Let us know about parking restrictions
- Tell us about access, such as stairs, a lift or high-level joints
