Remedial sealant & repairs in Gallows Corner, Greater London
Our applicators work in Gallows Corner on removing failed, mouldy or leaking sealant and putting it right. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Mould trapped under a layer of silicone
- Decorators’ caulk around a bath or shower
- Repeat leaks from the same joint
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Keep the room well ventilated
- Have loose fittings fixed before resealing
- Find out why the sealant failed first
- Use a soft cloth, not a scourer, on silicone
Watch the joint over the first few weeks, especially if movement was the problem. If anything changes, just ring 0345 464 0079 or send us an email.
Mould under a second layer of sealant keeps growing out of sight. When it finally shows, the whole bead needs to come out.
Remedial sealant for homes and businesses in Gallows Corner
A joint that keeps letting you down needs more than another bead. It helps to have photos when you ring 0345 464 0079 or drop us an email, and say how long ago it was last done. If you’re dealing with sealant peeling off a dusty or damp surface and worktop sealant that has shrunk and split, we can put it right.
Across London, a large share of homes are flats, conversions or mansion blocks, and many bathrooms sit right above someone else’s ceiling. That makes worn sealant and cracked grout in Gallows Corner more than a cosmetic job.
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.

Landlords, agents and businesses in Gallows Corner
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
The process
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours, depending on how many layers have to come out. In Gallows Corner, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- We start by checking the joint for movement, leaks and the reason it failed.
- Every layer of old sealant is cut and cleaned out.
- Next, any mould is treated and the joint dried.
- We use the right backing and sealant for any joint that moves.
- We tool the joint and tell you about anything else that needs attention.
Getting ready for the visit
- Keep children and pets away from the work area
- Mention any leaks or damp you’ve noticed
- Move anything stored near the joints

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

What sealant work can’t fix
Before you book, it’s worth knowing the limits too:
- A leaking trap, valve or supply pipe
- Cracks in the fitting rather than the joint
- Movement from fittings that are not supported
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly before booking.
Joints and surfaces we work on
- Shrunken worktop sealant
- Leaking tray & enclosure joints

- Expansion joints
- Failed movement joints
Why it’s worth doing now in Gallows Corner
Another bead over the top won’t fix a failed joint. It cannot bond to what’s underneath, so the leak carries on and there’s now more to remove. 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. Putting it right early is much less trouble for homes in Gallows Corner.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Different surfaces, different methods
Leaking trays & enclosures
A shower that leaks after resealing often has a tray that moves or an enclosure sealed on the wrong side. We check both before we reseal.
Worktops & kitchens
Kitchen joints often have grease and cleaning residue deep in them, so cleaning takes longer than in a bathroom before resealing.
What remedial sealant looks like in Gallows Corner
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. 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.
If you let a flat or house near Gidea Park station, botched sealant from a previous quick fix is easier to strip out between tenants. Schools such as Royal Liberty School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s. In the older streets around St Michael and All Angels Church, walls and floors in older homes can move, and sealant and grout show it first.

Common questions in Gallows Corner
Is parking an issue for remedial sealant in Gallows Corner?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.

Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before work begins.
Where are you based?

Do I have to be there?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all.
Can you reseal a split movement joint?
Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
