Specialist remedial sealant for Chiswick: the right sealant, proper preparation and a neat finish. Call for a quick quote.
- Movement joints that have split or pulled away
- A shower that leaks however often it’s resealed
- Products that weren’t meant for the joint
What happens if it’s left?
Spraying mould remover on a sealed-over joint doesn’t reach what’s underneath. 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 Chiswick.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and send you a clear quote before work begins.

How we handle remedial sealant in Chiswick
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint won’t last, however tidy it looks. We take it out and use a sealant made for that joint. We are often asked to deal with movement joints that have split or pulled away and sealant that came away because the surface wasn’t prepared, across expansion joints, mouldy bath & shower sealant and shrunken worktop sealant.
In much of London, period terraces have been converted into flats over the years, with bathrooms fitted into whatever space was available. Small, steamy rooms are where mould gets into sealant and grout fastest.
You’re covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you do try it yourself, take your time over the 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.
What sealant work can’t fix
We’d rather tell you now than do work that won’t last, so these are the limits:
- A leaking trap, valve or supply pipe
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- A bath, tray or worktop that moves until it’s properly fixed
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before you book.
What we seal
- Botched or over-sealed joints
- Expansion joints
- Failed movement joints
- Mouldy bath & shower sealant
- Shrunken worktop sealant
- Leaking tray & enclosure joints
What affects the cost of remedial sealant
We quote each job individually. This is what makes a difference:
- When we can work, for business premises
- The number and length of the joints
- How much old sealant there is and how hard it is to remove
- Access and height
What it costs depends on how much there is to do, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.

What the job involves on each surface
Movement & expansion joints
Joints filled with mortar, grout or rigid filler can’t move. Where it can be raked out, we replace it with flexible sealant.
Mouldy bath & shower sealant
Black mould inside the bead won’t scrub out. All of it comes out, and the joint is treated and dried ahead of a new anti-fungal bead.
FAQs for Chiswick
Can worn sealant in a flat in Chiswick cause a leak downstairs?
Yes. In a flat, water from a failed bath or shower seal has only one way to go, and that’s down. A proper reseal before the leak starts is the easy fix.
Is parking an issue for remedial sealant in Chiswick?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and you will get one quote.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We’ll tell you what we’re using and why.
What information do you need?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Where are you based?
We are based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
What if resealing won’t fix my leak?
You’ll hear it from us. A cracked tray, faulty valve or leaking waste needs a different trade, so we won’t pretend it will.
Can you take off two layers of silicone?
Yes. We cut out all the layers and clean off the film, before resealing with a single bead.
Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Hotels need rooms back in use, so we plan the work room by room. We have worked in hotels as well as homes and businesses.
Remedial sealant in Chiswick: local notes
London has hard water, which leaves limescale on sealant, grout and taps. 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.
Managing a site like The William Hogarth Primary School? Then we reseal washrooms and kitchens in schools and businesses as well as homes. As a London address, Chiswick can be tricky for parking: let us know about parking bays, permits or a driveway. For an older house near a landmark such as St. Nicholas Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

The process
There’s no need to move everything out, just the space around the work. We protect the rest, and the work takes a few hours for most joints, depending on how much old sealant has to come out for a typical job. In a London area like Chiswick, 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.
- 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.
- Once dry, a suitable sealant is applied and tooled.
- We give you the cure time and explain what caused the failure.
