Remedial sealant in Udimore, done properly
The wrong product in the wrong joint will not last, however tidy it looks. We take it out and use a sealant made for that joint. We work on failed movement joints, leaking tray & enclosure joints and mouldy bath & shower sealant, and common reasons people get in touch are smears and lumps from a botched reseal and mould trapped under a layer of silicone.
Homes around Udimore are mostly houses and cottages rather than flats. Sealant and grout wear out here just as they do anywhere: everything old comes out before the new sealant or grout goes in.
There’s a 12-month guarantee on every job, large or small.

Why deal with it now?
DIY removal often leaves scratches and a film of residue, and any film left behind stops new sealant sticking. Careful stripping is where most of our time goes. Around Udimore, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

How the visit works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself usually takes a few hours for most joints, depending on how much old sealant has to come out, depending on the size of the job. Somewhere as small as Udimore, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at how the sealant has failed and check for movement or a leak path.
- 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.
- The new joint is tooled neatly and we explain anything else we found.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Tell us about any water getting in
- Let us know about stairs, lifts or work at height

Advice
Honest limits
A few problems are outside what sealant work can do:
- Failed tanking or loose tiles behind the sealant
- Sealant in an older building that needs testing for asbestos first
- Leaks from a shower valve, waste or pipework (a plumber’s job)
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think before you book.
Joints and surfaces we work on
- Botched or over-sealed joints
- Mouldy bath & shower sealant
- Leaking tray & enclosure joints
- Expansion joints
- Failed movement joints
- Shrunken worktop sealant
Looking after it afterwards
After the cure time, these simple habits help:
- Keep an eye on the ceiling below the bathroom
- Never seal over old silicone
- Report a tray that rocks or a worktop that lifts
- Never fill a movement joint with mortar or grout
Clean gently: a mild cleaner and a soft cloth, with no blades or scourers.
Signs to act on: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Any of them means it’s time for remedial work.
Signs you need remedial sealant in Udimore
Even good sealant ages. Mould grows into the silicone, the surface hardens and the bead shrinks, faster where ventilation is poor. Then the only fix is removal and a new bead.
The most common problems we see are:
- Black mould underneath the bead
- Sealant that came away because the surface wasn’t prepared
- A shower that leaks however often it’s resealed
- Gaps opening along the back of the worktop
If you live in an older home near The Parish Church of St Mary, older homes can move a little, which is hard on rigid grout and tired sealant.

Questions from Udimore
Do you cover Udimore for remedial sealant?
Yes, Udimore is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job, and we will send you a clear quote.
Is Udimore within the area you cover?
Yes, Udimore is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
What if the leak is not the sealant?
We check for that before we reseal. If we find the leak is elsewhere, we tell you before going further.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Someone sealed over the old bead. Can you fix it?
Yes. Both layers come out; over-sealing fails because silicone will not bond to silicone.
Can landlords and businesses book you?
Yes, we do. Domestic, commercial and hotel work are all part of what we do, and we’re fully insured.
Can you match the sealant colour?
We will suggest a colour to suit the surroundings. The choice depends on the product the joint needs.
I’m a tenant. Can you help?
Of course. Ask your landlord first, and we can send them the quote if that helps.
Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
How the job changes by surface
Windows & doors
A frame that keeps leaking may not be the mastic. If the frame joint isn’t the cause, we’ll say so.
Movement & expansion joints
Joints filled with mortar, grout or rigid filler cannot move. We rake that out where it can be removed and seal with a flexible product.
Remedial sealant in Udimore: local notes
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Rented homes near Winchelsea station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
