About our remedial sealant in South Hornchurch
Water on the floor does not always mean failed silicone. A cracked tray, a failed shower valve or a leaking waste can look just the same. When the fault is elsewhere, we say so instead of resealing for the sake of it. If you are dealing with thick, messy sealant smeared over tiles and over-sealed joints coming away, we can put it right, whatever the surface.
Across London, a large share of homes are flats, conversions or mansion blocks, so a bathroom is often directly above a neighbour’s ceiling. That makes worn sealant and cracked grout in South Hornchurch more than a cosmetic job.
Our work is backed for twelve months.

Remedial sealant around South Hornchurch
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.
South Hornchurch is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. For landlords with property near Rainham (Essex) station, a joint that keeps failing is best fixed properly while the property is empty.

What else we do in South Hornchurch
Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Surface by surface
Movement & expansion joints
A movement joint must be able to stretch. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed with a low-modulus product.
Over-sealed & botched joints
Previous removal attempts can leave scratches or gouges. We take care not to make it worse, and tell you about any damage we find.
Questions from South Hornchurch
I live in a flat in South Hornchurch. Can a failed seal leak into the flat below?
Yes, it can. Water that gets past failed sealant or cracked grout can run under the bath or tray and show up 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 Rainham (Essex) station?
Yes, we work for landlords and letting agents. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Can you take off two layers of silicone?
Yes. It’s slower than a standard reseal, because every layer has to come out cleanly, but it’s the only way the new joint will last.
Do you cover South Hornchurch?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland.
Is it messy?
Tidy work is part of the job. We protect what’s around the joints.
Will the old sealant be removed?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
What we cannot put right
New sealant can’t fix everything, and we’d rather say so up front. It won’t solve:
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Water damage behind tiles that needs a tiler
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
If you’re not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer before booking.
Joints and surfaces we work on
- Expansion joints
- Mouldy bath & shower sealant
- Failed movement joints
- Botched or over-sealed joints
- Shrunken worktop sealant
- Leaking tray & enclosure joints
Signs you need remedial sealant in South Hornchurch
Movement tears sealant that isn’t designed for it. A bath that flexes, a tray that rocks or a building joint that opens and closes split any bead that is too stiff or too thin.
Look out for any of the following:
- Torn expansion joints
- Sealant applied over old sealant that has lifted
- Mould trapped under a layer of silicone
- Sealant that came away because the surface wasn’t prepared
For site and facilities teams at buildings such as Whybridge Junior School, 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.

How it works
You don’t need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the work takes a few hours for most joints, depending on how much old sealant has to come out in most cases. In a London area like South Hornchurch, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Each layer is cut out and the residue cleaned off.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you’re told about anything else we found.
Preparing for the visit
- On commercial sites, let us know about site rules
- Mention any leaks or damp you’ve noticed
- Tell us if parking is tricky

How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Act on a lifting corner straight away
- Get the cause of a repeat leak found before resealing
- Report a tray that rocks or a worktop that lifts
- Run the fan after every shower
Clean gently: a mild cleaner and a soft cloth, with no blades or scourers.
Signs to act on: 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.
