About our remedial sealant in Little Chelsea
Two decades of sealant work means we recognise most failures quickly. We’re ARBOMaster approved and fully insured, and every remedial job comes with a 12-month guarantee. Typical jobs include worktop sealant that has shrunk and split and a shower that leaks however often it’s resealed, across botched or over-sealed joints, mouldy bath & shower sealant and expansion joints.
In much of London, period terraces have been converted into flats over the years, with bathrooms fitted into whatever space was available. A compact bathroom that steams up every day is hard on silicone and grout.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

What affects the cost of remedial sealant
Call for a quick quote. The main things that affect it are:
- Which sealant suits the joint
- Access and height
- Any mould that needs treating
- Working hours on commercial sites
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, call 0345 464 0079 or email us and we will give you an honest view and a quote.
Asking for a quote
Photos by email are helpful but not essential. Try to tell us:
- How we’d reach the joints
- If it’s domestic, commercial or a hotel
- What’s wrong with the joints now
- Roughly how big the job is
Want a quote for remedial sealant? Please ring 0345 464 0079 or drop us an email with a few details. You’ll know what we plan to do, and what it will cost, before any work begins.
What we do, step by step
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a typical bath or shower, longer where several layers have been applied. In Little Chelsea, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- 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.
Getting ready for the visit
- Mention any tricky access
- Let us know about earlier repairs to the joints
- Move anything stored near the joints

Why deal with it now?
Ripping out a bathroom is not normally needed. When the fittings are sound, stripping and resealing the joints is often enough. Where something else has failed, you will hear it from us. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Little Chelsea, the repair is bigger than a sealant job.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.
Why book with us
- 180+ five-star Google reviews

- We are fully insured
- Anti-fungal silicone where joints get wet

Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Little Chelsea homes and their sealant
London has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. 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.
In the older streets around Church of St Andrew, timber floors under older bathrooms flex, so joints need a sealant that moves with them. Little Chelsea is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

What we cannot put right
A few problems are outside what sealant work can do:
- A bath, tray or worktop that moves until it’s properly fixed
- Cracks in the fitting rather than the joint
- A leaking trap, valve or supply pipe
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly before booking.
What we seal
- Leaking tray & enclosure joints
- Botched or over-sealed joints
- Shrunken worktop sealant
- Expansion joints
- Failed movement joints
- Mouldy bath & shower sealant
How the job changes by surface
Mouldy bath & shower sealant
Where mould keeps coming back, ventilation is normally part of the cause. We will reseal and tell you if extraction looks to be the issue.
Worktops & kitchens
If a worktop moves when you lean on it, the sealant will keep splitting. It needs fixing down first, which we’ll point out.
Common problems we fix in Little Chelsea
Products get mixed up: caulk where it gets wet, rigid sealant where things move, or an acetoxy silicone on a surface it can mark. Each fails in its own way.
The problems people normally mention when they call include:
- Kitchen joints letting water behind the worktop
- Smears and lumps from a botched reseal
- Sealant applied over old sealant that has lifted
- Sealant peeling off a dusty or damp surface
Rented homes near Imperial Wharf station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Your questions about remedial sealant in Little Chelsea
Can worn sealant in a flat in Little Chelsea cause a leak downstairs?
Yes. In a flat, water from a failed bath or shower seal has only one way to go, and that’s down. Cutting out the old sealant and laying a new bead early stops it getting that far.
Is parking a problem for a job in Little Chelsea?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Do you fix expansion and movement joints?
Yes. If a joint has been filled with mortar or rigid filler, we rake it out where possible, and reseal with a flexible product.
Can you take off two layers of silicone?
Yes. Each layer is cut out and the residue cleaned off, then the joint is resealed once.
How long does remedial resealing take?
Longer than a simple reseal, because every layer has to come out. For most joints, it’s a few hours.
I’m a tenant. Can you help?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
Do you guarantee remedial jobs?
Yes. You get our 12-month guarantee.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
