How we handle remedial sealant in West Brompton
Water on the floor doesn’t always mean failed silicone. A cracked tray, a failed shower valve or a leaking waste can look just the same. If that is what we find, we will tell you rather than reseal something that will not fix it. We work on failed movement joints, shrunken worktop sealant and leaking tray & enclosure joints, and people most often call us about repeat leaks from the same joint and products that weren’t meant for the joint.
In much of London, period terraces have been converted into flats over the years, and bathrooms were often squeezed into small rooms. A compact bathroom that steams up every day is hard on silicone and grout.
Every job comes with our one-year guarantee, wherever you are in Greater London.

Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Common problems we fix in West Brompton
How a joint is built matters as much as the product. A bead bonded on three sides, or laid too thick, cannot flex, so it tears when the joint moves. Backing rod or bond-breaker tape prevents it.
The most common problems we see are:
- Black mould underneath the bead
- Worktop sealant that has shrunk and split
- Repeat leaks from the same joint
- Wide, uneven beads that look worse than the old ones
As a London address, West Brompton can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Aftercare tips
Aftercare is simple:
- Keep an eye on the ceiling below the bathroom
- Ask why a joint failed before redoing it
- Never fill a movement joint with mortar or grout
- Clean sealant with mild products only
Don’t let anyone seal over it later. New silicone doesn’t bond to old, so the old bead should always come out first.
A failing joint rarely gets better on its own. Each use pushes more water behind the bead, into whatever is behind or below. Early action keeps it to a sealant job.

Remedial sealant in West Brompton: local notes
London has hard water, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in. West Brompton has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.
For an older house near a landmark such as Church of St Luke, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. Schools such as St Cuthbert with St Matthias CofE Primary School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes.

The process
We keep the work tidy and contained to the joints we are treating, so you can carry on as normal. The job normally takes a few hours for a typical bath or shower, longer where several layers have been applied. In West Brompton, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- Once dry, a suitable sealant is applied and tooled.
- We give you the cure time and explain what caused the failure.
Before we arrive
- Let us know about parking restrictions
- Keep pets and children clear of the area while we work
- Mention any leaks or damp you’ve noticed

When something else is needed
We will not take on work that will not last, so these are the limits:
- Failed tanking or loose tiles behind the sealant
- A cracked shower tray or bath (that needs repair or replacing)
- Sealant in an older building that needs testing for asbestos first
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly.
What we seal
- Leaking tray & enclosure joints
- Botched or over-sealed joints
- Expansion joints
- Failed movement joints
- Mouldy bath & shower sealant
- Shrunken worktop sealant
What happens if it’s left?
Stripping out botched sealant adds time to a reseal, but not by much: the work takes a few hours for most joints, depending on how much old sealant has to come out. It’s far less disruption than resealing the same joint again and again. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in West Brompton, the repair is bigger than a sealant job.
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or drop us an email.

Your questions about remedial sealant in West Brompton
Do you take on hotel work around West Brompton?
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.
I let a flat near West Brompton station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll send you a clear quote.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
What does remedial sealant cost?
It depends on the job, so we quote each one individually. To get one, ring 0345 464 0079 or email us and tell us what needs doing and where.
Is remedial work guaranteed?
Yes. You get our 12-month guarantee.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
How long should I leave it?
Cure times vary by product and the temperature. We tell you how long to leave it before we go.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Surface by surface
Windows & doors
Frames resealed over the top end up with hard, layered mastic. We remove it all and clean back to sound surfaces before backing and resealing.
Movement & expansion joints
A sealant stuck to the back of the joint cannot stretch. Backing stops that, so the sealant grips the two sides only.
