Remedial sealant in Coombe
Some sealant jobs are not a simple reseal, because someone has already had a go. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all have to come out. We work on shrunken worktop sealant, botched or over-sealed joints and expansion joints, and the jobs we see most are a shower that leaks however often it’s resealed and sealant that came away because the surface wasn’t prepared.
Around Coombe, it’s houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. Sealant and grout wear out here just as they do anywhere: old material cut out, joints cleaned and a fresh finish laid.
Every job is covered by our 12-month guarantee.

Do you need remedial sealant in Coombe?
Sealant needs a clean, dry surface with no grease on it. Soap film, dust, damp or old residue stop it gripping, so it starts lifting sooner than it should.
Any of these means the joints need attention:
- Black mould underneath the bead
- Repeat leaks from the same joint
- Caulk or the wrong sealant used in a wet area
- Kitchen joints letting water behind the worktop
If you live in an older home near Church of St Peter and St Paul, timber floors under older bathrooms flex, so joints need a sealant that moves with them.
Questions to ask before booking
- Is the old sealant removed completely?
- Who turns up on the day
- What product goes in the joint
- What preparation is included
Coombe homes and their sealant
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
For site and facilities teams at buildings such as Great Kimble Church of England School, 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. Rented homes near Little Kimble station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Why act early in Coombe
Mould under a bead cannot be reached by cleaning. The layers have to come out. Around Coombe, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, 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.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Looking after it afterwards
So the new joints stay in good condition:
- Check ceilings under showers for marks
- Clean sealant with mild products only
- Have loose fittings fixed before resealing
- Don’t point over movement joints
Ventilation keeps mould away from the new bead: use the extractor or open a window after showering.
Leaks through failed sealant grow over time. Each use pushes more water behind the bead, into floors, walls or ceilings. Early action keeps it to a sealant job.
What we cannot put right
Sealant is not the answer to every problem, and we will tell you before work begins. It won’t solve:
- A cracked shower tray or bath (that needs repair or replacing)
- Tiles that have come away from the wall
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
If in doubt, call 0345 464 0079 or email us and we’ll say what we think.
What we seal
- Botched or over-sealed joints

What happens on the day
We bring everything the job needs with us. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take a few hours for most joints, depending on how much old sealant has to come out. Somewhere like Coombe needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Each layer is cut out and the residue cleaned off.
- We treat any mould and dry the joint thoroughly.
- The right product goes in, with backing where the joint moves.
- We finish neatly and point out anything that needs another trade.
How to prepare
- Mention any parking rules near the property
- Mention any sign-in or site rules at work premises
- Clear the area around the work

Do you cover Coombe for remedial sealant?

Can you fix a reseal that hasn’t worked?
Yes. Repeat leaks usually come from over-sealing, movement or water getting in elsewhere, and we deal with the cause first.
What happens if the problem is the tray or the plumbing?
We will tell you. A cracked tray, faulty valve or leaking waste needs a different trade, so we will not pretend it will.
Can you reseal a split movement joint?
Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.
Someone sealed over the old bead. Can you fix it?
Yes. It’s slower than a standard reseal, because every layer has to come out cleanly, but it’s what makes the new bead last.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
How long does the work take?
Longer than a simple reseal, because every layer has to come out. For most joints, it’s a few hours.
