How we quote for remedial sealant
Some jobs are bigger than they look, and some smaller. What affects the quote:
- How easy the joints are to reach
- How much old sealant there is and how hard it is to remove
- The number and length of the joints
- Any working-time requirements on site
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
What we need to know
What to tell us when you ask for a quote:
- Pictures of the joints, sent by email
- Where the job is, and your postcode
- Whether it has been sealed before
- The problem you’ve noticed
Every job is quoted individually, so the first step is telling us about yours. Just call 0345 464 0079 or email us with the details and send pictures if you have them.
Remedial sealant in Farringdon, done properly
Not every leak is a sealant leak. Cracked trays, leaking wastes and faulty valves often look like a sealant problem. When the fault is elsewhere, we say so instead of resealing for the sake of it. We work on leaking tray & enclosure joints, mouldy bath & shower sealant and failed movement joints, and common reasons people get in touch are decorators’ caulk around a bath or shower and torn expansion joints.
In much of London, period terraces have been converted into flats over the years, and bathrooms were often squeezed into small rooms. Small, steamy rooms are where mould gets into sealant and grout fastest, and homes in Farringdon are no different.
There’s a 12-month guarantee on every job, whatever its size.

Remedial sealant in Farringdon: local notes
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. London’s water is hard, which leaves limescale on sealant, grout and taps.
Schools such as Charterhouse Square School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Farringdon is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

How it works
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours for a typical bath or shower, longer where several layers have been applied, depending on the size of the job. In Farringdon, 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 start by checking the joint for movement, leaks and the reason it failed.
- All the old sealant comes out, including any layers underneath.
- We clean the joint, treat any mould and let it dry.
- Moving joints get backing and a flexible sealant to suit.
- The new joint is tooled neatly and we explain anything else we found.
Before we arrive
- Move anything stored near the joints
- For business premises, tell us about site rules or sign-in
- Tell us if parking is tricky

Common questions in Farringdon
Can you help a landlord with a rental near Farringdon station?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Can parking be tricky for a visit in Farringdon?
Parking in Farringdon, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Where are you based?
We work from Crawley. We cover Farringdon and the rest of Greater London, along with the rest of our area.
Can failed expansion joints be resealed?
Yes. If a joint has been filled with mortar or rigid filler, we rake it out where possible, and reseal with a flexible product.
Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. Indoors, that usually means someone at home.
Will there be a smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Sealant in an older building that needs testing for asbestos first
- Tiles that have come away from the wall
- A bath, tray or worktop that moves until it’s properly fixed
If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.

Do you need remedial sealant in Farringdon?
Some joints fail because water is reaching them from behind. A leaking valve, a failed waste or cracked grout feeds water behind the bead, and the sealant lifts or goes mouldy from underneath.
The problems people usually mention when they call include:
- Black mould underneath the bead
- A shower that leaks however often it’s resealed
- Kitchen joints letting water behind the worktop
- Movement joints that have split or pulled away
Letting a property close to Farringdon station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Why act early in Farringdon
Mould under a bead can’t be reached by cleaning. The layers have to come out, and the joint treated and dried before resealing. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Farringdon, the repair is bigger than a sealant job.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
