Remedial sealant in Sundridge
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint won’t last, however tidy it looks. Out it comes, and in goes a sealant suited to the job. If you’re dealing with movement joints that have split or pulled away and mould trapped under a layer of silicone, we can help, whatever the surface.
Much of London’s older housing is Victorian and Edwardian terraces, many of them now split into flats, and bathrooms were often squeezed into small rooms. Small, steamy rooms are where mould gets into sealant and grout fastest.
Every job is covered by a one-year guarantee.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
What happens on the day
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours, depending on how many layers have to come out from start to finish. In a London area like Sundridge, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.
- 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.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you’re told about anything else we found.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Let us know about earlier repairs to the joints
- For business premises, tell us about site rules or sign-in

Bathrooms and kitchens in Sundridge
London’s water is hard, which leaves limescale on sealant, grout and taps. Sundridge 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.
Sundridge is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. If you look after a building such as St Joseph's Catholic Primary 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.

Questions from Sundridge
Could a tired shower seal in my Sundridge flat affect the neighbours 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. Replacing the sealant and grout before that happens is much less trouble than repairing a neighbour’s ceiling.
Do you work for landlords with property near Sundridge Park station?
Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.
Someone resealed my shower and it’s leaking again. Can you help?
Yes, usually. First we check whether the leak is the sealant at all, then strip and reseal the joints.
What should I tell you?
The location, the problem and the rough size of the job. If you can, email a few pictures.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator.
What the job involves on each surface
Leaking trays & enclosures
Repeat shower leaks often come from a tray that flexes or an enclosure sealed in the wrong place. We check both before any new sealant goes on.
Windows & doors
Failed frame mastic is often hard, cracked and in several layers. We remove it all and clean back to sound surfaces.
Honest limits
We will not take on work that won’t last, so here’s what sealant can’t put right:
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- A cracked shower tray or bath (that needs repair or replacing)
- A bath, tray or worktop that moves until it’s properly fixed
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think before you book.
What we seal
- Expansion joints
- Shrunken worktop sealant
- Failed movement joints
- Leaking tray & enclosure joints
- Botched or over-sealed joints
- Mouldy bath & shower sealant
Signs you need remedial sealant in Sundridge
Some joints fail because water is reaching them from behind. A leaking valve, a failed waste or cracked grout feeds water behind the bead, so the silicone goes mouldy or lets go.
The most common problems we see are:
- Beads that never stuck properly
- Products that weren’t meant for the joint
- Sealant applied over old sealant that has lifted
- Worktop sealant that has shrunk and split
For landlords with property near Sundridge Park station, botched sealant from a previous quick fix is easier to strip out between tenants.
