Brasted Chart Remedial Sealant
Failed sealant joints in Brasted Chart need attention? We cut out the old, prepare the joints and apply the right sealant, with a one-year guarantee.
- Wide, uneven beads that look worse than the old ones
- Caulk or the wrong sealant used in a wet area
- Repeat leaks from the same joint
DIY sealant or a professional job?
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.
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. All the old material has to come out first.
Remedial sealant in Brasted Chart
Movement and expansion joints fail when the sealant cannot stretch. The old sealant comes out and backing goes in to control the depth, before resealing with a flexible product suited to the movement. We work on failed movement joints, shrunken worktop sealant and mouldy bath & shower sealant, and common reasons people get in touch are beads that never stuck properly and gaps opening along the back of the worktop.
London homes include a lot of flats, conversions and mansion blocks, and many bathrooms sit right above someone else’s ceiling. In Brasted Chart, that is a good reason to put tired sealant and grout right early.
Your job is guaranteed for a year, as with all our work.

Signs you need remedial sealant in Brasted Chart
Joint depth matters. Sealant packed too deep, or stuck to the back of the joint as well as the sides, cannot stretch, and tears at the first real movement. Backing rod or bond-breaker tape prevents it.
The problems people normally mention when they call are:
- Decorators’ caulk around a bath or shower
- Leaks that keep coming back after resealing
- Movement joints that have split or pulled away
- Smears and lumps from a botched reseal
For an older house near a landmark such as Church of St Martin, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

What remedial sealant looks like in Brasted Chart
London has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. 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.
Brasted Chart is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. If you let a flat or house near Sevenoaks station, a joint that keeps failing is best fixed properly while the property is empty.

The process
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours, depending on how many layers have to come out. In Brasted Chart, 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 start by checking the joint for movement, leaks and the reason it failed.
- We strip the joint completely, removing any layers below.
- We clean the joint, treat any mould and let it dry.
- Moving joints get backing and a flexible sealant to suit.
- We tool the joint and tell you about anything else that needs attention.
How to prepare
- On commercial sites, let us know about site rules
- Keep children and pets away from the work area
- Tell us about any water getting in

Related advice
Keeping the joints in good condition
So the new joints stay in good condition:
- Get the cause of a repeat leak found before resealing
- Check ceilings under showers for marks
- Air the bathroom so the sealant can dry
- Do not wait for a small gap to become a leak
Ventilation keeps mould away from the new bead: use the extractor or open a window after showering.
Mould under a second layer of sealant keeps growing out of sight. When it finally shows, the whole bead needs to come out.
Common questions in Brasted Chart
Can you help a landlord with a rental near Sevenoaks station?
Yes, we work for landlords and agents. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Do you work for hotels and guest houses in Brasted Chart?
Yes, hospitality work, including hotels, is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Do you take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Do you cover Brasted Chart?
Yes. We are based in Crawley and work across South East England, London and Scotland.
Do you guarantee remedial jobs?
Yes, for 12 months. If we have pointed out another problem, getting it fixed helps the new joint last.
Can you take off two layers of silicone?
Yes. Stripping layered sealant takes longer than a normal reseal, but it’s the only way the new joint will last.
What if the leak is not the sealant?
We check for that before we reseal. If we find the leak is elsewhere, we tell you before going further.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is usually more efficient.
Leave it or put it right?
Remedial work takes longer than a straight reseal, but not by much: the work 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. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in Brasted Chart.
What it costs 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, so you know where you stand.

- Working hours on commercial sites
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
