When to call us in Kent Street
All sealant wears out eventually. Mould grows into the silicone, the surface hardens and the bead shrinks, faster where ventilation is poor. At that point it has to come out.
People generally contact us after spotting something like this:
- Sealant that came away because the surface wasn’t prepared
- Gaps opening along the back of the worktop
- Black mould underneath the bead
- Smears and lumps from a botched reseal
In and around Kent Street, as anywhere, good remedial sealant starts with a clean, dry, properly prepared joint.

Remedial sealant for homes and businesses in Kent Street
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint fails however neatly it’s applied. We take it out and use a sealant made for that joint. We work on botched or over-sealed joints, shrunken worktop sealant and leaking tray & enclosure joints, and common reasons people get in touch are a second bead peeling off the first and products that weren’t meant for the joint.
Around Kent Street, it’s houses and cottages rather than flats. The work is the same as anywhere: old material cut out, joints cleaned and a fresh finish laid.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Why deal with it now?
It’s easy to scratch acrylic, enamel or an uPVC frame cutting out old sealant, and the residue left behind stops the next bead bonding. Careful removal is most of a remedial job. Around Kent Street, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
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 we start, so you know where you stand.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. 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.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

How to look after the new joints
To keep the joints looking good and working properly:
- Look for stains below bathrooms now and then
- Get the cause of a repeat leak found before resealing
- Check trays and worktops don’t move
- Don’t wait for a small gap to become a leak
Don’t let anyone seal over it later. New silicone does not bond to old.
If a joint has failed more than once, stop resealing it. Get the cause found first, otherwise the next attempt will fail too.
What we do, step by step
At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours, depending on how many layers have to come out, depending on the amount of work. In a small place like Kent Street, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Surrounding tiles, trays and frames are protected first.
- The botched or failed sealant is cut away completely.
- 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.
- You get the cure time and our view on why the joint failed.
Before we arrive
- On commercial sites, let us know about site rules
- For indoor joints, keep the area dry beforehand if you can
- Mention if the joints have been sealed before

Surface by surface
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.
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.
What remedial sealant looks like in Kent Street
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.
