Remedial sealant in Royal Docks
Water on the floor does not always mean failed silicone. Cracked trays, leaking wastes and faulty valves often look like a sealant problem. When the fault is elsewhere, we say so instead of resealing for the sake of it. We work on mouldy bath & shower sealant, expansion joints and shrunken worktop sealant, and common reasons people get in touch are movement joints that have split or pulled away and sealant peeling off a dusty or damp surface.
London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. In Royal Docks, remedial sealant is as much about a room looking cared for as about keeping water out.
The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or send us an email.

What happens if it’s left?
Remedial work takes longer than a straight reseal, but not by much: it takes a few hours, depending on how many layers have to come out. It’s far less disruption than resealing the same joint again and again. In a flat in Royal Docks, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or email us and we’ll give you an honest view and a quote.

How the job changes by surface
Movement & expansion joints
A sealant stuck to the back of the joint can’t stretch. Backing stops that, letting the sealant flex between the two faces.
Leaking trays & enclosures
When failed joints are the cause, they’re all cut out and renewed, tray edges and screen profiles included.
What we cannot put right
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Plumbing leaks behind walls or under trays
- Tiles that have come away from the wall
- Cracks in the fitting rather than the joint
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.
What we seal
- Failed movement joints
- Botched or over-sealed joints

Can I do it myself?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
What remedial sealant looks like in Royal Docks
London’s water is hard, which leaves limescale on sealant, grout and taps. Royal Docks has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and can be done room by room.
Schools such as Calverton 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 Custom House station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. Homes close to Church of the Ascension include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Royal Docks questions
Can you help a landlord with a rental near Custom House station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll send you a clear quote.
Do you take on hotel work around Royal Docks?
Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.
What happens if the problem is the tray or the plumbing?
In that case, we tell you what we have found. You may need a plumber or bathroom fitter before any new sealant goes on.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in.
Where do you work from?
We are a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator.
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 you take off two layers of silicone?
Yes. We remove every layer; new silicone doesn’t bond to old silicone, which is why over-sealing fails.
What happens on the day
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours, depending on how many layers have to come out. In Royal Docks, 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.
- The joint is cleaned, treated for mould and left to dry.
- We use the right backing and sealant for any joint that moves.
- Finally we finish the joint and talk you through what we found.
Getting ready for the visit

- Where the joints are inside, avoid wetting them before we arrive
