Remedial sealant in Lyneham
A movement joint stops working when its sealant splits or sets hard. We cut out the failed sealant and set the depth with backing, then a flexible sealant matched to the movement goes in. If you have kitchen joints letting water behind the worktop and black mould underneath the bead, we can help.
For a small place like Lyneham, remedial sealant is planned like any other job: it just means planning the journey and access beforehand. In the bathroom or kitchen, the work is the same as in any town.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

What remedial sealant looks like in Lyneham
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
If you let a flat or house near Shipton station, a joint that keeps failing is best fixed properly while the property is empty.

Surface by surface
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. Once it’s all removed, the joint is treated so the new sealant starts clean.
Movement & expansion joints
A movement joint must be able to stretch. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed.
Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
What we cannot put right
Before you book, it’s worth knowing the limits too:
- A leaking trap, valve or supply pipe
- Cracks in the fitting rather than the joint
- Failed tanking or loose tiles behind the sealant
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think.
What we seal
- Botched or over-sealed joints
- Leaking tray & enclosure joints
- Mouldy bath & shower sealant
- Shrunken worktop sealant
- Failed movement joints
- Expansion joints
How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Never fill a movement joint with mortar or grout
- Deal with small splits early
- Keep bleach and abrasives off the bead
- Keep the room well ventilated
Give the new sealant its full cure time: follow the cure time we give you.
A split movement joint lets rain into walls and floors, and left long enough, the edges of the joint can crumble. Resealing while the edges are sound is simpler.

What we do, step by step
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours for a typical bath or shower, longer where several layers have been applied. In a small place like Lyneham, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Surrounding tiles, trays and frames are protected first.
- The botched or failed sealant is cut away completely.
- We clean and degrease the joint and look for signs of movement or water.
- New sealant goes in once the joint is dry, and is tooled smooth.
- You get the cure time and our view on why the joint failed.
Before we arrive
- Try not to wet indoor joints just before the visit
- Mention if the joints have been sealed before
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Why act early in Lyneham
Hidden water does the most damage: soaked floorboards, ceiling stains below and blown plaster. Dealing with the joint now is a small job by comparison. Where a wall is exposed, as many are in small places like Lyneham, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

FAQs for Lyneham
I let a flat near Shipton station. Can you help?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear price.
Do you cover smaller places like Lyneham?
Yes. Lyneham is within the area we cover, which takes in towns, villages and rural addresses. 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?
Possibly a little. Any smell clears as the sealant cures.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.
How much does remedial sealant cost in Lyneham?
Size, access and the old material all affect the cost. Ask us for a quote and we’ll talk you through it.
Can you remove sealant that’s been put over old sealant?
Yes. Stripping layered sealant takes longer than a normal reseal, but it’s the only way the new joint will last.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. Then call 0345 464 0079 or send us an email.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
Common problems we fix in Lyneham
One of the commonest remedial jobs is sealant on top of sealant. New silicone can’t stick to the old bead, so the new layer peels, and damp and mould settle between them.
Signs it’s time to call us include:
- Kitchen joints letting water behind the worktop
- Sealant applied over old sealant that has lifted
- Products that weren’t meant for the joint
- Sealant that came away because the surface wasn’t prepared
In and around Lyneham, as anywhere, good remedial sealant starts with a clean, dry, properly prepared joint.
