Signs you need remedial sealant in Sway
One of the commonest remedial jobs is sealant on top of sealant. New silicone cannot stick to the old bead, so the top layer lifts and water and mould collect between the two.
The problems people usually mention when they call are:
- Thick, messy sealant smeared over tiles
- Dark patches showing through the sealant
- Torn expansion joints
- Kitchen joints letting water behind the worktop
In the older streets around St Luke's Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

How the visit works
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes a few hours for most joints, depending on how much old sealant has to come out from start to finish. For a job in Sway, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We start by checking the joint for movement, leaks and the reason it failed.
- We strip the joint completely, removing any layers below.
- We clean the joint, treat any mould and let it 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.
Before we arrive
- Try not to wet indoor joints just before the visit
- Let us know if you’ve seen damp or leaks
- Let us know about earlier repairs to the joints

For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Check trays and worktops do not move
- Keep an eye on the ceiling below the bathroom
- Never seal over old silicone
- Get the cause of a repeat leak found before resealing
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 send us an email.
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.
Can I do it myself?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Questions from Sway
Do you cover Sway for remedial sealant?
Yes, Sway is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job, and we will send you a clear quote.
Is Sway within the area you cover?
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.
How long does the work take?
A little longer than a standard reseal. Most jobs take a few hours, and we confirm the time with your quote.
Do you have insurance?
Yes. We’re fully insured, and we can confirm the details when we quote.
I rent my home. Can I book you?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
Someone resealed my shower and it’s leaking again. Can you help?
Yes. There’s normally a reason: sealant over sealant, movement or another leak, and we deal with the cause first.
What does remedial sealant cost?
Every job is different, so each one gets its own quote. For a quick quote, ring 0345 464 0079 or drop us an email and let us know what needs doing and where.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access.
Why it’s worth doing now in Sway
DIY removal often leaves scratches and a film of residue, and any film left behind stops new sealant sticking. Careful removal is most of a remedial job. In an older home around Sway, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Leaving a failed joint usually makes the job bigger, not smaller. If you are unsure, ring 0345 464 0079 or email us for an honest opinion and a quote.

Sway homes and their sealant
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.
Schools such as St Luke's Church of England Primary School are buildings too, and 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. Letting a property close to Sway station? Then a joint that keeps failing is best fixed properly while the property is empty.
