Remedial sealant in Bishopsgate, done properly
In Bishopsgate, as anywhere, remedial jobs tend to look alike: over-sealed joints, hidden mould, repeat leaks and split movement joints. We strip each one back and start from scratch. If you have decorators’ caulk around a bath or shower and a shower that leaks however often it’s resealed, we can put it right, on expansion joints, leaking tray & enclosure joints and failed movement joints alike.
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, and homes in Bishopsgate are no different.
A one-year guarantee comes as standard, so you are covered after we have gone.

Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
What sealant work can’t fix
A few problems are outside what sealant work can do:
- Sealant in an older building that needs testing for asbestos first
- A tray or worktop that needs refixing first
- A cracked shower tray or bath (that needs repair or replacing)
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly.
Joints and surfaces we work on
- Failed movement joints
- Mouldy bath & shower sealant
- Leaking tray & enclosure joints
- Expansion joints
- Shrunken worktop sealant
- Botched or over-sealed joints
Different surfaces, different methods
Movement & expansion joints
Bonding on three sides is a common reason movement joints tear. Backing rod or bond-breaker tape prevents it, so the sealant grips the two sides only.
Worktops & kitchens
A loose worktop splits its sealant. That needs refixing before resealing, which we’ll point out.
What affects the quote in Bishopsgate
We quote each job individually. These are the things that affect it:
- The number and length of the joints
- How easy the joints are to reach
- Which sealant suits the joint
- Working hours on commercial sites
Doing several joints on one visit is normally more efficient than separate visits. You will get one clear quote for the whole job.
Asking for a quote
To make quoting easier, let us know:
- Whether it has been sealed before
- What the problem is, such as mould, gaps, leaks or cracking
- Access, such as stairs, a lift or height
- Where the job is, and your postcode
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. Whenever you’re ready, call 0345 464 0079 or drop us an email.
What remedial sealant looks like in Bishopsgate
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. There are hotels and other places to stay in and around Bishopsgate. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.
Schools such as The London School of Barbering are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s. If you let a flat or house near London Liverpool Street station, a joint that keeps failing is best fixed properly while the property is empty.

Aftercare tips
After the cure time, these simple habits help:
- Report a tray that rocks or a worktop that lifts
- Use a soft cloth, not a scourer, on silicone
- Keep the room well ventilated
- Deal with small splits early
Clean gently: a mild cleaner and a soft cloth, with no blades or scourers.
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.
Signs you need remedial sealant in Bishopsgate
Sealant needs a clean, dry surface with no grease on it. Residue, moisture or dust left in the joint weaken the bond, and the joint starts to come away early.
It’s worth asking for a quote if you see:
- A shower that leaks however often it’s resealed
- Worktop sealant that has shrunk and split
- Sealant applied over old sealant that has lifted
- Thick, messy sealant smeared over tiles
As a London address, Bishopsgate can be tricky for parking: let us know about parking bays, permits or a driveway.

Your questions about remedial sealant in Bishopsgate
Do you take on hotel work around Bishopsgate?
Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.
I live in a flat in Bishopsgate. Can a failed seal leak into the flat below?
Yes, it can. Water that gets past failed sealant or cracked grout can run under the bath or tray and show up on the ceiling below. Replacing the sealant and grout before that happens is much less trouble than repairing a neighbour’s ceiling.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
Can tenants book the work?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Is remedial work guaranteed?
Yes. Remedial work carries the same 12-month guarantee as all our work.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
The process
At the end, we look at the finished work together and tell you how long to leave it. The visit itself usually takes a few hours for most joints, depending on how much old sealant has to come out, depending on how much there is to do. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- First we work out whether the problem is the sealant, movement or a leak.
- Each layer is cut out and the residue cleaned off.
- Mould is treated and the joint dried.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you are told about anything else we found.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Let us know about earlier repairs to the joints
- For indoor joints, keep the area dry beforehand if you can
