- Products that weren’t meant for the joint
- Thick, messy sealant smeared over tiles
- Sealant peeling off a dusty or damp surface
Aftercare tips
After the cure time, these simple habits help:
- Clean sealant with mild products only
- Always have old sealant cut out, not covered
- Keep movement joints clear of mortar and paint
- Look for stains below bathrooms now and then
Keep an eye on the joint at first, particularly where the original failure was caused by movement. Should anything change, ring 0345 464 0079 or drop us an email.
Leaks through failed sealant grow over time. Every shower or downpour sends more water through, into whatever is behind or below. Early action keeps it to a sealant job.

FAQs for Upper Swanmore
Do you cover Upper Swanmore for remedial sealant?
Yes. We work across London and the South East, and Upper Swanmore is part of that. You can call 0345 464 0079 or email us and tell us what needs doing.
Will you come out to Upper Swanmore?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Can you remove sealant that’s been put over old sealant?
Yes. Both layers come out; over-sealing fails because silicone won’t bond to silicone.

The process
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. It generally takes a few hours, depending on how many layers have to come out. In a small place like Upper Swanmore, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- Finally we finish the joint and talk you through what we found.
Getting ready for the visit
- Tell us if parking is tricky
- Clear items away from the joints we are working on
- Let us know if you’ve seen damp or leaks

Can I do it myself?
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.
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 does not work out, we can still put it right.

Leave it or put it right?
A joint that has failed twice will fail again unless the cause is dealt with. Finding it, whether movement, water from elsewhere or an unsuitable product, ends the cycle. In a small place like Upper Swanmore, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
The cost depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before any work starts.

Common problems we fix in Upper Swanmore
One of the commonest remedial jobs is sealant on top of sealant. New silicone cannot stick to the old bead, so the new layer peels, and damp and mould settle between them.
Most people get in touch after spotting one of these:
- Thick, messy sealant smeared over tiles
- Sealant peeling off a dusty or damp surface
- Mould trapped under a layer of silicone
- Over-sealed joints coming away
If you live in an older home near Church of St Barnabas, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

When something else is needed
Sealant isn’t the answer to every problem, and we’ll tell you before work begins. Sealant won’t put right:
- Tiles that have come away from the wall
- Cracks in the fitting rather than the joint
- A bath, tray or worktop that moves until it’s properly fixed
