Locksbottom Remedial Sealant
Problem with your failed sealant joints in Locksbottom? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Sealant peeling off a dusty or damp surface
- A shower that leaks however often it’s resealed
- Over-sealed joints coming away
What we are called out for in Locksbottom
Even good sealant ages. Over the years it shrinks, hardens and gets colonised by mould, faster where ventilation is poor. Then the only fix is removal and a new bead.
If you can see any of these, it’s time to have the joints looked at:
- Gaps opening along the back of the worktop
- Floor or wall movement joints that have failed
- Smears and lumps from a botched reseal
- Leaks that keep coming back after resealing
Managing a site like Darrick Wood Infant & Nursery School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
What your quote should include
- How the colour is chosen
- How the surfaces are prepared before sealing
- When the joint can take water or movement
- Whether the sealant suits the joint
Remedial sealant in Locksbottom
A joint that keeps failing normally has a reason. A tray that moves, a worktop that isn’t fixed, the wrong sealant or water getting in elsewhere will beat any new bead. Finding that cause comes before any new sealant. We work on shrunken worktop sealant, failed movement joints and botched or over-sealed joints, and the jobs we see most are repeat leaks from the same joint and decorators’ caulk around a bath or shower.
Across London, a large share of homes are flats, conversions or mansion blocks, so a bathroom is often directly above a neighbour’s ceiling. That makes worn sealant and cracked grout in Locksbottom more than a cosmetic job.
You get a 12-month guarantee, the same in Locksbottom as everywhere else we work.

What we do, step by step
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take a few hours, depending on how many layers have to come out. For a job in Locksbottom, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- We protect the surfaces around the joint.
- 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
- Tell us about any water getting in
- Keep pets and children clear of the area while we work
- For business premises, tell us about site rules or sign-in

Advice
Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
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. Everything old must be removed first.
When something else is needed
We won’t take on work that will not last, so here’s what sealant can’t put right:
- Tiles that have come away from the wall
- Plumbing leaks behind walls or under trays
- A bath, tray or worktop that moves until it’s properly fixed
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly before booking.
What we seal
- Failed movement joints
- Botched or over-sealed joints
- Mouldy bath & shower sealant
- Shrunken worktop sealant
- Leaking tray & enclosure joints
- Expansion joints
Leave it or put it right?
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. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
A failed joint rarely gets cheaper to fix by waiting. If you are unsure, phone 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

FAQs for Locksbottom
I let a flat near Orpington station. Can you help?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear quote.
Is parking an issue for remedial sealant in Locksbottom?
Parking in Locksbottom, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Can you remove sealant that is been put over old sealant?
Yes. We remove every layer; over-sealing fails because silicone will not bond to silicone.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we have agreed the job, you don’t need to watch us work.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Is remedial work guaranteed?
Yes. Our one-year guarantee covers the work, and we are fully insured.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
What does remedial sealant cost?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You will get a clear quote before we start.
Keeping the joints in good condition
Looking after new joints is easy:
- Do not add new sealant on top of old
- Don’t point over movement joints
- Check trays and worktops don’t move
- Look for stains below bathrooms now and then
Go easy on the new sealant: no scraping, scouring pads or harsh chemicals.
Signs to act on: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Each one is worth getting looked at.
Bathrooms and kitchens in Locksbottom
In a London flat, water from a failed bath or shower seal can reach the neighbours below, so tired sealant is best dealt with early. London’s water is hard, so limescale builds up on sealant, grout and fittings.
Rented homes near Orpington station change hands often, and a joint that keeps failing is best fixed properly while the property is empty. As a London address, Locksbottom can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
