Remedial sealant in Broadfields Estate, done properly
Not every leak is a sealant leak. A cracked tray, a failed shower valve or a leaking waste can look just the same. When the fault is elsewhere, we say so instead of resealing for the sake of it. If you are dealing with kitchen joints letting water behind the worktop and movement joints that have split or pulled away, we can help, on leaking tray & enclosure joints, expansion joints and botched or over-sealed joints alike.
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.
Every job is covered by our 12-month guarantee.

Common problems we fix in Broadfields Estate
Products get mixed up: caulk where it gets wet, rigid sealant where things move, or an acetoxy silicone on a surface it can mark. Each fails in its own way.
Keep an eye out for these signs:
- Beads that never stuck properly
- Over-sealed joints coming away
- Caulk or the wrong sealant used in a wet area
- Repeat leaks from the same joint
Broadfields Estate is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

How the job changes by surface
Windows & doors
A frame that keeps leaking may not be the mastic. We check the joint and tell you if it looks to be something else.
Leaking trays & enclosures
Repeat shower leaks often come from a tray that flexes or an enclosure sealed in the wrong place. Both are checked before we reseal.
What happens if it’s left?
Leaks that are left keep doing damage out of sight: wet floors, stained ceilings and swollen worktops. By comparison, sorting the joint is quick. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Broadfields Estate, the repair is bigger than the sealant job would have been.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

How we quote for remedial sealant
The quote reflects the job in front of us. We look at:
- Whether old sealant or filler has to be cut out
- Any mould that needs treating
- The size of the job
- Working hours on commercial sites
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
What we need to know
To help us quote quickly, let us know:
- Any access issues, like height or stairs
- Whether it’s a home or a business
- Pictures of the joints, sent by email
- The problem you’ve noticed
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is. When it suits you, phone 0345 464 0079 or email us.
How it works
You don’t need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for a typical bath or shower, longer where several layers have been applied in most cases. In Broadfields Estate, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Each layer is cut out and the residue cleaned off.
- We treat any mould and dry the joint thoroughly.
- The right product goes in, with backing where the joint moves.
- We finish neatly and point out anything that needs another trade.
Getting ready for the visit
- Mention if the joints have been sealed before
- Move anything stored near the joints
- For business premises, tell us about site rules or sign-in

Advice
What remedial sealant looks like in Broadfields Estate
There are hotels and other places to stay in and around Broadfields Estate. Hotel bathrooms are part of our work as well as homes, and can be done room by room. London has hard water, which leaves limescale on sealant, grout and taps.
Homes close to St Andrew include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them. Schools such as Rosh Pinah Primary School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes.

Questions from Broadfields Estate
Do you work in hotels near Broadfields Estate?
Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.
Is parking an issue for remedial sealant in Broadfields Estate?
Parking in Broadfields Estate, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient.
Where are you based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
When is the sealant fully cured?
It depends on the product and the temperature. Before we leave, we will tell you the cure time.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can you remove sealant that’s been put over old sealant?
Yes. Both layers come out; new silicone does not bond to old silicone, which is why over-sealing fails.
When it isn’t the sealant
We will always be straight with you, so here’s what sealant can’t fix:
- Movement from fittings that are not supported
- A tray or bath that is cracked
- Plumbing leaks behind walls or under trays
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think.
