Lullingstone Remedial Sealant
We cover Lullingstone for removing failed, mouldy or leaking sealant and putting it right. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Repeat leaks from the same joint
- Sealant that came away because the surface wasn’t prepared
- Gaps opening along the back of the worktop
Remedial sealant for homes and businesses in Lullingstone
Removing failed sealant is the hardest part of the job. Every layer is cut out, the residue cleaned off and the joint degreased, without scratching tiles, trays or frames. Only then can new sealant bond. We work on shrunken worktop sealant, botched or over-sealed joints and mouldy bath & shower sealant, and the jobs we see most are smears and lumps from a botched reseal and black mould underneath the bead.
Somewhere as small as Lullingstone, 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.
A one-year guarantee comes as standard.

DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Common problems we fix in Lullingstone
One of the commonest remedial jobs is sealant on top of sealant. Silicone doesn’t bond to silicone, so the top layer lifts and water and mould collect between the two.
Look out for any of the following:
- Smears and lumps from a botched reseal
- Black mould underneath the bead
- Worktop sealant that has shrunk and split
- Sealant peeling off a dusty or damp surface
If you live in an older home near Church of Saint Botolph, older homes can move a little, which is hard on rigid grout and tired sealant.
What to look for in a quote
- How long to leave it before use
- Whether they’re fully insured
- The length of the guarantee
- Whether all the old sealant comes out first
Looking after it afterwards
Aftercare is simple:
- Ask why a joint failed before redoing it
- Keep movement joints clear of mortar and paint
- Report a tray that rocks or a worktop that lifts
- Keep bleach and abrasives off the bead
Leave the new joint to cure fully before it gets wet or moves: generally around 24 hours, or as long as we advise.
Signs to act on: sealant lifting at the ends, a second bead visible on top of the first, black mould under the silicone, or stains below a bathroom. Any of them means it’s time for remedial work.
What we can’t put right
Some problems need a builder, plumber or other trade rather than us:
- A tray or worktop that needs refixing first
- Sealant in an older building that needs testing for asbestos first
- Tiles that have come away from the wall
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think before booking.
Where we work in Lullingstone
- Botched or over-sealed joints
- Failed movement joints
- Mouldy bath & shower sealant
- Expansion joints
- Leaking tray & enclosure joints
- Shrunken worktop sealant
Leave it or put it right?
Leaks that are left keep doing damage out of sight: wet floors, stained ceilings and swollen worktops. Dealing with the joint now is a small job by comparison. Older cottages and farmhouses around Lullingstone can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, ring 0345 464 0079 or email us for an honest opinion and a quote.

What we do, step by step
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes a few hours for a typical bath or shower, longer where several layers have been applied, depending on the size of the job. In a small place like Lullingstone, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you are told about anything else we found.
Before we arrive
- Mention any tricky access
- Tell us if parking is tricky
- Let us know about earlier repairs to the joints

Different surfaces, different methods
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. We treat the exposed joint once the bead is out so the new sealant starts clean.
Movement & expansion joints
Movement joints in floors, walls and façades need a flexible sealant set to the right depth. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed with a low-modulus product.
