Remedial sealant in Smithfield, done properly
Water on the floor does not always mean failed silicone. 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 have sealant that came away because the surface wasn’t prepared and gaps opening along the back of the worktop, we can put it right.
Hard London water leaves limescale on sealant, grout and taps alike. For a bathroom or kitchen in Smithfield, getting the joints right keeps water where it belongs and the room looking clean.
Your job is guaranteed for a year, as with all our work.

Why deal with it now?
Remedial work takes longer than a straight reseal, but not by much: it takes a few hours, depending on how many layers have to come out. Compared with chasing the same leak every few months, it’s time well spent. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and give you a clear quote before work begins.

How it works
At the end, we look at the finished work together and tell you how long to leave it. The visit itself normally takes a few hours for a typical bath or shower, longer where several layers have been applied, depending on the amount of work. For a job in Smithfield, parking and access are the things to plan: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- First we find out how and where the joint has failed.
- All the old sealant comes out, including any layers underneath.
- We clean the joint, treat any mould and let it dry.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- We tool the joint and tell you about anything else that needs attention.
How to prepare
- Clear items away from the joints we are working on
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any parking rules near the property

Common questions in Smithfield
Do you take on hotel work around Smithfield?
Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Could a tired shower seal in my Smithfield flat affect the neighbours below?
Yes. In a flat, water from a failed bath or shower seal has only one way to go, and that is down. A proper reseal before the leak starts is the easy fix.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Do you cover Smithfield?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland.
Can you fix a reseal that hasn’t worked?
Yes. Repeat leaks usually come from over-sealing, movement or water getting in elsewhere, and we deal with the cause first.
Will the old sealant be removed?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
What if resealing won’t fix my leak?
We’ll tell you. A cracked tray, faulty valve or leaking waste needs a different trade, so we will not pretend it will.
What do you need from me for a quote?
Let us know what needs doing and where, with pictures by email if possible. If we need more, we’ll ask.
How the job changes by surface
Windows & doors
Failed frame mastic is often hard, cracked and in several layers. All of it is cut out and the frame and wall cleaned before backing and resealing.
Movement & expansion joints
Movement joints in floors, walls and façades need a flexible sealant set to the right depth. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed with a low-modulus product.
What sealant work can’t fix
Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:
- Sealant in an older building that needs testing for asbestos first
- A leaking trap, valve or supply pipe
- A bath, tray or worktop that moves until it’s properly fixed
If in doubt, ring 0345 464 0079 or email us and we will say what we think before you book.
Surfaces we seal
- Shrunken worktop sealant
- Botched or over-sealed joints
- Leaking tray & enclosure joints
- Failed movement joints
- Mouldy bath & shower sealant
- Expansion joints

What else we do in Smithfield
What remedial sealant looks like in Smithfield
London’s water is hard, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, so tired sealant is best dealt with early.
If you look after a building such as Charterhouse Square School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. For an older house near a landmark such as St Bartholomew-the-Less, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. As a London address, Smithfield can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

DIY sealant or a professional job?
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.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Use a soft cloth, not a scourer, on silicone
- Run the fan after every shower
- Never seal over old silicone
- Act on a lifting corner right away
Leave the new joint to cure fully before it gets wet or moves: follow the cure time we give you.
A split movement joint lets rain into walls and floors, and the longer it’s left, the more the joint edges break down. A joint with sound edges is far easier to reseal.
