How we handle remedial sealant in Kevington
Not every leak is a sealant leak. 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 expansion joints, failed movement joints and mouldy bath & shower sealant, and common reasons people get in touch are mould trapped under a layer of silicone and a second bead peeling off the first.
Across London, a large share of homes are flats, conversions or mansion blocks, so a bathroom is often directly above a neighbour’s ceiling. In Kevington, that’s a good reason to put tired sealant and grout right early.
All of our work is guaranteed for twelve months, in Kevington and everywhere else we cover.

Kevington questions
Do you work for landlords with property near St Mary Cray 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.
Could a tired shower seal in my Kevington flat affect the neighbours below?
Yes, and the first sign is often a stain on the ceiling below. Cutting out the old sealant and laying a new bead early stops it getting that far.
Do you offer different sealant colours?
Most of the time, yes. We will tell you which colours the right product comes in.
Does remedial work come with a guarantee?
Yes. Remedial work carries the same 12-month guarantee as all our work.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Looking after it afterwards
After the cure time, these simple habits help:
- Have loose fittings fixed before resealing
- Don’t add new sealant on top of old
- Run the fan after every shower
- Ask why a joint failed before redoing it
Clean gently: no scraping, scouring pads or harsh chemicals.
Leaks through failed sealant grow over time. Each use pushes more water behind the bead, into floors, walls or ceilings. Sorting it early limits the damage.
Remedial sealant around Kevington
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, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in.
As a London address, Kevington can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. For site and facilities teams at buildings such as Manor Oak Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes.

Landmarks near Kevington
In Kevington, that means homes and buildings near The Priory School and Harris Academy Orpington. The nearest railway station is St Mary Cray station, roughly 1.4 miles north-west. Nearby you’ll also find Lullingstone Castle (3.2 miles south-east) and London Borough of Bromley Museum (1.5 miles west). Green spaces nearby include Summer Hill and The Warren.
Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
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.
How the visit works
The work is kept neat and contained to the area we’re working on. Expect the work to take a few hours, depending on how many layers have to come out, and we explain the cure time before we leave. In Kevington, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- We protect the surfaces around the joint.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.
- New sealant goes in once the joint is dry, and is tooled smooth.
- We give you the cure time and explain what caused the failure.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- For business premises, tell us about site rules or sign-in
- Tell us about access, such as stairs, a lift or high-level joints

Signs you need remedial sealant in Kevington
Using the wrong product is a common cause: caulk where it gets wet, rigid sealant where things move, or an acetoxy silicone on a surface it can mark. Each fails in its own way.
Any of these means the joints need attention:
- Smears and lumps from a botched reseal
- Gaps opening along the back of the worktop
- Floor or wall movement joints that have failed
- Over-sealed joints coming away
In the older streets around Unity Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.
What to look for in a quote
- What happens if they find a problem under the old sealant
- What the cure time is
- How much experience the applicator has
- How the joint is cleaned and prepared
Different surfaces, different methods
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
A shower that leaks after resealing often has a tray that moves or an enclosure sealed on the wrong side. Both are checked before any new sealant goes on.
Honest limits
A few problems are outside what sealant work can do:
- A tray or bath that is cracked
- Sealant in an older building that needs testing for asbestos first
- Plumbing leaks behind walls or under trays
If you’re not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.

Why deal with it now?
Ripping out a bathroom isn’t normally needed. If the bath, tray and tiles are sound, remedial resealing normally puts it right. Where something else has failed, you will hear it from us. In a flat in Kevington, 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.
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins.
