Lyminster Remedial Sealant
Removing failed, mouldy or leaking sealant and putting it right for homes and businesses in Lyminster and across West Sussex. Fully insured, ARBOMaster approved and guaranteed for a year.

- Dark patches showing through the sealant
- Beads that never stuck properly
Remedial sealant in Lyminster, done properly
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. Only then can new sealant bond. If you have sealant that came away because the surface wasn’t prepared and caulk or the wrong sealant used in a wet area, we can put it right.
For a small place like Lyminster, remedial sealant is planned like any other job: it just means planning the journey and access beforehand. Once we are there, the bathroom or kitchen gets the same care as anywhere else.
All of our work is guaranteed for twelve months.

The process
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a few hours for most joints, depending on how much old sealant has to come out, including the tidy-up. For a village or hamlet like Lyminster, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking the joint for movement, leaks and the reason it failed.
- Every layer of old sealant is cut and cleaned out.
- The joint is cleaned, treated for mould and left to dry.
- We use the right backing and sealant for any joint that moves.
- We tool the joint and tell you about anything else that needs attention.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Clear the area around the work
- Mention if the joints have been sealed before
How to get a quote

Advice
What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- A bath, tray or worktop that moves until it’s properly fixed
- Failed tanking or loose tiles behind the sealant
- Leaks from a shower valve, waste or pipework (a plumber’s job)
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly before booking.
Joints and surfaces we work on
- Leaking tray & enclosure joints
- Mouldy bath & shower sealant
- Shrunken worktop sealant
- Botched or over-sealed joints
- Expansion joints
- Failed movement joints
Different surfaces, different methods
Movement & expansion joints
Joints filled with mortar, grout or rigid filler can’t move. Where it can be raked out, we replace it with flexible sealant.
Mouldy bath & shower sealant
Mould that has grown into silicone does not clean out for good. All of it comes out, and the joint is treated and dried ahead of a new anti-fungal bead.

What else we do in Lyminster
Common questions in Lyminster
Do you work for hotels and guest houses in Lyminster?
Yes, hospitality work, including hotels, is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Do you cover smaller places like Lyminster?
Yes, Lyminster is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can I add another job to the visit?
Yes. Just list everything you need and we’ll quote it together.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Can failed expansion joints be resealed?
Yes. Backing sets the depth and stops the sealant sticking to the back.
Someone sealed over the old bead. Can you fix it?
Yes. Each layer is cut out and the residue cleaned off, then the joint is resealed once.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
How much does remedial sealant cost in Lyminster?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before work begins.
What affects the quote in Lyminster
Jobs vary more than people expect. What affects the quote:
- The product the joint needs
- The amount of work
- Whether there’s mould to deal with
- Access and height
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
What we need to know
When you contact us, it’s useful to know:
- What’s wrong with the joints now
- If someone has resealed it before
- Roughly how big the job is
- The address or postcode of the job
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. When it suits you, ring 0345 464 0079 or email us.
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

Leave it or put it right?
Repeat failures have a cause. Finding it, whether movement, water from elsewhere or an unsuitable product, ends the cycle. Where a wall is exposed, as many are in small places like Lyminster, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What it costs depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts.

Signs you need remedial sealant in Lyminster
Movement tears sealant that isn’t designed for it. A bath that flexes, a tray that rocks or a building joint that opens and closes split any bead that is too stiff or too thin.
The most common problems we see are:
- Sealant that came away because the surface wasn’t prepared
- Caulk or the wrong sealant used in a wet area
- Over-sealed joints coming away
- Repeat leaks from the same joint
If you live in an older home near The Parish Church of St Mary Magdalen, timber floors under older bathrooms flex, so joints need a sealant that moves with them.
