Kensal Town Remedial Sealant
We cover Kensal Town for removing failed, mouldy or leaking sealant and putting it right. Old sealant removed completely, joints prepared properly.
- Mould trapped under a layer of silicone
- Floor or wall movement joints that have failed
- Smears and lumps from a botched reseal
Remedial sealant in Kensal Town, done properly
If a joint fails again and again, something is causing it. A tray that moves, a worktop that isn’t fixed, the wrong sealant or water getting in elsewhere will beat any new bead. We look for the cause before we reseal. We work on expansion joints, botched or over-sealed joints and failed movement joints, and people most often call us about mould trapped under a layer of silicone and torn expansion joints.
Much of London’s older housing is Victorian and Edwardian terraces, many of them now split into flats, with bathrooms fitted into whatever space was available. A compact bathroom that steams up every day is hard on silicone and grout, and homes in Kensal Town are no different.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

Honest limits
We’ll always be straight with you, so here’s what sealant cannot fix:
- A leaking trap, valve or supply pipe
- A tray or bath that’s cracked
- A bath, tray or worktop that moves until it’s properly fixed
If in doubt, phone 0345 464 0079 or email us and we will say what we think.
What we seal
- Botched or over-sealed joints
- Mouldy bath & shower sealant
- Failed movement joints
- Shrunken worktop sealant
- Expansion joints
- Leaking tray & enclosure joints
The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a typical bath or shower, longer where several layers have been applied and we leave things clean and tidy. In Kensal Town, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- We look at how the sealant has failed and check for movement or a leak path.
- We strip the joint completely, removing any layers below.
- We clean the joint, treat any mould and let it dry.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- We tool the joint and tell you about anything else that needs attention.
Before we arrive
- Let us know about parking restrictions
- For indoor joints, keep the area dry beforehand if you can
- Mention any leaks or damp you’ve noticed

Landlord and commercial work in Kensal Town
We work for letting agents and landlords as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Different surfaces, different methods
Leaking trays & enclosures
When failed joints are the cause, they’re all cut out and renewed, tray edges and screen profiles included.
Worktops & kitchens
Old kitchen sealant pulls back from the wall over time. We strip it, degrease the joint and reseal in a colour to suit.

Signs you need remedial sealant in Kensal Town
A lot of failed joints have been sealed over rather than replaced. Silicone doesn’t bond to silicone, so the top layer lifts and water and mould collect between the two.
The most common problems we see are:
- Repeat leaks from the same joint
- Caulk or the wrong sealant used in a wet area
- Black mould underneath the bead
- Sealant that came away because the surface wasn’t prepared
If you live in an older home near St Thomas Kensal Town, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

Should I try it myself first?
If you are 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 fails, we can still redo it.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Why deal with it now?
Mould under a bead cannot be reached by cleaning. The layers have to come out, so the joint can be treated and resealed. In London conversions, one flat’s bathroom is often above another flat’s ceiling, 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 Kensal Town.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

What remedial sealant looks like in Kensal Town
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. London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, which is why it’s worth fixing early.
As a London address, Kensal Town can be tricky for parking: let us know about parking bays, permits or a driveway. If you let a flat or house near Queens Park (London) station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
