Remedial sealant in Haggerston
If a joint has been resealed and is leaking again, it’s worth a proper look. It helps to have pictures when you phone 0345 464 0079 or email us, along with when it was last resealed. If you are dealing with worktop sealant that has shrunk and split and smears and lumps from a botched reseal, we can put it right, whatever the surface.
Hard London water leaves limescale on sealant, grout and taps alike. For a bathroom or kitchen in Haggerston, getting the joints right keeps water where it belongs and the room looking clean.
Whatever the size of the job, it’s backed by our one-year guarantee in Haggerston and across Greater London.

When it isn’t the sealant
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- A bath, tray or worktop that moves until it’s properly fixed
- Older mastics that may need an asbestos check before removal
- Failed tanking or loose tiles behind the sealant
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think.
What we seal
- Failed movement joints
- Leaking tray & enclosure joints
- Shrunken worktop sealant
- Mouldy bath & shower sealant
- Expansion joints
- Botched or over-sealed joints
Haggerston: your questions answered
I live in a flat in Haggerston. Can a failed seal leak into the flat below?
Yes, and the first sign is often a stain on the ceiling below. A proper reseal before the leak starts is the easy fix.
Can you help a landlord with a rental near Hoxton station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we will send you a clear quote.
How long before the joint can be used?
Cure times vary by product and the temperature. Before we leave, we’ll tell you the cure time.
Can you reseal a split movement joint?
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 old silicone be taken off without scratching the tiles?
Yes, with care. We cut and lift the old sealant with tools suited to the surface, and the residue is cleaned away. We point out any damage that is already there.
Does remedial work come with a guarantee?
Yes. Our one-year guarantee covers the work, and we’re ARBOMaster approved.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Where do you work from?
We’re based in Crawley, and we work across South East England, London and Scotland.
How the visit works
There is not much for you to do on the day. Show us the job and we’ll take it from there. The work itself takes a few hours for a typical bath or shower, longer where several layers have been applied. In Haggerston, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- First we work out whether the problem is the sealant, movement or a leak.
- 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.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- For business premises, tell us about site rules or sign-in
- Clear items away from the joints we are working on

Advice
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Check ceilings under showers for marks
- Check trays and worktops do not move
- Deal with small splits early
- Air the bathroom so the sealant can dry
Don’t let anyone seal over it later. New silicone doesn’t bond to old.
A failing joint rarely gets better on its own. Every shower or downpour sends more water through, into floors, walls or ceilings. Early action keeps it to a sealant job.

What remedial sealant looks like in Haggerston
London’s water is hard, which leaves limescale on sealant, grout and taps. 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.
Homes close to Church of St Columba include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant. If you let a flat or house near Hoxton station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. Managing a site like Randal Cremer Primary School? Then 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.

What affects the cost of remedial sealant
The quote reflects the job in front of us. We look at:
- Whether old sealant or filler has to be cut out
- The type of sealant required
- How many rooms, windows or areas are involved
- Any working-time requirements on site
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Helping us quote
Before you ask for a quote, have a think about:
- What’s wrong with the joints now
- Whether it has been sealed before
- The type of property
- Where the property is
It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. Whenever you’re ready, phone 0345 464 0079 or drop us an email.
What happens if it’s left?
A failed seal rarely means a new bathroom. When the fittings are sound, stripping and resealing the joints is often enough. If they’re not, we will tell you. In a flat in Haggerston, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins.
Why book with us
- Tidy, careful work
- We are fully insured
- Arbo and Everbuild products
- We never seal over old sealant

Surface by surface
Movement & expansion joints
Joints filled with mortar, grout or rigid filler cannot move. Where it can be raked out, we replace it with flexible sealant.
Worktops & kitchens
Shrunken worktop sealant leaves a gap that lets water into the back edge. It’s cut out, degreased and resealed colour-matched to the worktop.
