Remedial sealant in Shirley, done properly
If a joint fails again and again, something is causing it. A tray that moves, a worktop that isn’t fixed, the wrong sealant or water getting in elsewhere will defeat even a perfect bead. We look for the cause before we reseal. If you have smears and lumps from a botched reseal and mould trapped under a layer of silicone, we can help, whatever the surface.
In much of London, period terraces have been converted into flats over the years, and bathrooms were often squeezed into small rooms. Small, steamy rooms are where mould gets into sealant and grout fastest.
Big or small, it’s backed by our 12-month guarantee.

DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.

What happens on the day
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. Most jobs then take a few hours for most joints, depending on how much old sealant has to come out. In Shirley, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- We look at how the sealant has failed and check for movement or a leak path.
- We strip the joint completely, removing any layers below.
- Next, any mould is treated and the joint dried.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- Finally we finish the joint and talk you through what we found.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Where the joints are inside, avoid wetting them before we arrive
- Mention any tricky access

Related advice
Shirley: your questions answered
Is parking an issue for remedial sealant in Shirley?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Can you help a landlord with a rental near Elmers End station?
Yes. We work for landlords and letting agents as well as householders, and several properties can go on one quote. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Do the sealants smell?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
Are you insured?
Yes, we are fully insured.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Do you guarantee remedial jobs?
Yes. Our one-year guarantee covers the work, and we are fully insured.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned.
Can you fix a reseal that hasn’t worked?
Yes. Repeat leaks generally come from over-sealing, movement or water getting in elsewhere, and we deal with the cause first.
What we cannot put right
A few problems are outside what sealant work can do:
- Older mastics that may need an asbestos check before removal
- Water damage behind tiles that needs a tiler
- A cracked shower tray or bath (that needs repair or replacing)
If you are not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.
What we seal
- Expansion joints
- Mouldy bath & shower sealant
- Shrunken worktop sealant
- Botched or over-sealed joints
- Failed movement joints
- Leaking tray & enclosure joints
How to look after the new joints
So the new joints stay in good condition:
- Don’t add new sealant on top of old
- Air the bathroom so the sealant can dry
- Use a soft cloth, not a scourer, on silicone
- Look for stains below bathrooms now and then
If we’ve found a cause, such as a loose tray or a leaking waste, get it fixed, because the new sealant can’t hold back a problem underneath.
Warning signs: sealant lifting at the ends, a second bead visible on top of the first, black mould under the silicone, or stains below a bathroom. Any of them means it’s time for remedial work.
Remedial sealant around Shirley
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, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Schools such as Oasis Academy Shirley Park are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes. Letting a property close to Elmers End station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. As a London address, Shirley can be tricky for parking: 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 thick bead smeared across tiles often hides mould or gaps. Taking it back shows what’s underneath.
Worktops & kitchens
Old kitchen sealant pulls back from the wall over time. We strip it, degrease the joint and reseal in a colour to suit.
Leave it or put it right?
Spraying mould remover on a sealed-over joint doesn’t reach what’s underneath. The layers have to come out, and the joint treated and dried before resealing. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in Shirley.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll go through it with you.
