About our remedial sealant in Chinatown
Remedial jobs in Chinatown normally fall into a few patterns: over-sealed joints, hidden mould, repeat leaks and split movement joints. We strip each one back and start from scratch. We work on mouldy bath & shower sealant, leaking tray & enclosure joints and expansion joints, and people most often call us about beads that never stuck properly and caulk or the wrong sealant used in a wet area.
London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. For a bathroom or kitchen in Chinatown, getting the joints right keeps water where it belongs and the room looking clean.
Each job carries a 12-month guarantee, large or small.

What happens on the day
You don’t need to clear the whole room or building, only the area right around the joints. We protect the rest, and the job takes a few hours, depending on how many layers have to come out in most cases. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- We look at how the sealant has failed and check for movement or a leak path.
- Every layer of old sealant is cut and cleaned out.
- The joint is cleaned, treated for mould and left to dry.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- The new joint is tooled neatly and we explain anything else we found.
Before we arrive
- Tell us about any water getting in
- Clear the area around the work
- Tell us about access, such as stairs, a lift or high-level joints

Honest limits
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- Plumbing leaks behind walls or under trays
- Failed tanking or loose tiles behind the sealant
- A tray or worktop that needs refixing first
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly.

What else we do in Chinatown
Work for landlords, hotels and businesses

What remedial sealant looks like in Chinatown
In a London flat, water from a failed bath or shower seal can reach the neighbours below, which is why it’s worth fixing early. London’s water is hard, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in.
Schools such as Soho Parish CofE Primary School are buildings too, and 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 Tottenham Court Road station change hands often, and botched sealant from a previous quick fix is easier to strip out between tenants.

Signs you need remedial sealant in Chinatown
One of the commonest remedial jobs is sealant on top of sealant. New silicone cannot stick to the old bead, so the new layer peels, and damp and mould settle between them.
It’s worth asking for a quote if you see:
- Over-sealed joints coming away
- Beads that never stuck properly
- Gaps opening along the back of the worktop
- Black mould underneath the bead
As a London address, Chinatown can be tricky for parking: let us know about parking bays, permits or a driveway.
Comparing quotes
- Is VAT in the price?
- Whether the sealant suits the joint
- How the surfaces are prepared before sealing
- The length of the guarantee
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Have loose fittings fixed before resealing
- Find out why the sealant failed first
- Keep an eye on the ceiling below the bathroom
- Act on a lifting corner right away
Don’t let anyone seal over it later. New silicone does not bond to old.
Do not keep resealing the same joint. Have someone find out why, otherwise the next attempt will fail too.
Quotes for remedial sealant in Chinatown
Every job gets its own quote. This is what makes a difference:
- Whether old sealant or filler has to be cut out
- The product the joint needs
- Mould in or behind the old joints
- Access and height
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, ring 0345 464 0079 or send us an email for an honest opinion and a quote.

Do you work in Chinatown?
Yes. We are based in Crawley and work across South East England, London and Scotland, and that includes Chinatown.
What does remedial sealant cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Someone resealed my shower and it’s leaking again. Can you help?
Yes, normally. First we check whether the leak is the sealant at all, then strip and reseal the joints.
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, then the joint is sealed properly.

Just the basics: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or email us.
What the job involves on each surface
Leaking trays & enclosures
Repeat shower leaks often come from a tray that flexes or an enclosure sealed in the wrong place. Both are checked before any new sealant goes on.
Worktops & kitchens
Old kitchen sealant pulls back from the wall over time. We strip it, degrease the joint and reseal colour-matched to the worktop.
