How we handle remedial sealant in Hoxton
Some sealant jobs aren’t 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 need stripping out before the joint can be done properly. We work on leaking tray & enclosure joints, expansion joints and failed movement joints, and common reasons people get in touch are sealant applied over old sealant that has lifted and mould trapped under a layer of silicone.
London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. In Hoxton, remedial sealant is as much about a room looking cared for as about keeping water out.

When to call us in Hoxton
One of the commonest remedial jobs is sealant on top of sealant. Silicone does not bond to silicone, so the new layer peels, and damp and mould settle between them.
Most people get in touch when they notice something like this:
- A shower that leaks however often it’s resealed
- Movement joints that have split or pulled away
- Beads that never stuck properly
- Caulk or the wrong sealant used in a wet area
Rented homes near Hoxton station change hands often, and a joint that keeps failing is best fixed properly while the property is empty.

Leave it or put it right?
Ripping out a bathroom isn’t usually needed. If the bath, tray and tiles are sound, remedial resealing normally puts it right. Where something else has failed, you’ll hear it from us. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

Can I do it myself?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Hoxton homes and their sealant
Hoxton has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room. London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, so tired sealant is best dealt with early.
In the older streets around Church of St Anne with St Columba, older homes can move a little, which is hard on rigid grout and tired sealant. Hoxton is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

What the job involves on each surface
Over-sealed & botched joints
A botched joint can hide two or three layers of sealant, including the smears and film on surrounding tiles. Only a clean joint will take a new bead.
Worktops & kitchens
If a worktop moves when you lean on it, the sealant will keep splitting. That needs refixing before resealing, and we will tell you if we find it.
How it works
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for most joints, depending on how much old sealant has to come out. For a job in Hoxton, parking and access are the things to plan: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- First we find out how and where the joint has failed.
- We strip the joint completely, removing any layers below.
- Next, any mould is treated and the joint dried.
- Moving joints get backing and a flexible sealant to suit.
- The new joint is tooled neatly and we explain anything else we found.
Getting ready for the visit
- Tell us about any water getting in
- Clear items away from the joints we’re working on
- On commercial sites, let us know about site rules

Hoxton: your questions answered
Could a tired shower seal in my Hoxton flat affect the neighbours below?
It can, yes: water that gets past a split bead or cracked grout often runs under the tray and shows on the ceiling below. It’s far simpler to replace tired sealant early than to deal with a neighbour’s ceiling.
Do you work for landlords with property near Hoxton station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
Can old silicone be taken off without scratching the tiles?
Yes. Residue is removed with a product suited to the surface rather than scraped hard.
Can failed expansion joints be resealed?
Yes. The depth is set with backing so the sealant only bonds to the two sides.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We will tell you what we are using and why.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned.
Where do you work from?
We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
What if the leak isn’t the sealant?
Then we explain what we’ve found. You may need a plumber or bathroom fitter.
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Report a tray that rocks or a worktop that lifts
- Check ceilings under showers for marks
- Act on a lifting corner straight away
- Keep bleach and abrasives off the bead
If the joint ever needs renewing, have it cut out, not sealed over. Over-sealing is how many remedial jobs start.
Movement joints that have split let water into the structure, and left long enough, the edges of the joint can crumble. A joint with sound edges is far easier to reseal.
