We cover Nash for removing failed, mouldy or leaking sealant and putting it right. Old material cut out, joints cleaned and sealed neatly.

About our remedial sealant in Nash
Removing failed sealant is the hardest part of the job. Every layer is cut out, the residue cleaned off and the joint degreased, without scratching tiles, trays or frames. Only then can new sealant bond. We work on botched or over-sealed joints, shrunken worktop sealant and expansion joints, and people most often call us about gaps opening along the back of the worktop and caulk or the wrong sealant used in a wet area.
London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. For a bathroom or kitchen in Nash, getting the joints right keeps water where it belongs and the room looking clean.
Every job comes with a one-year guarantee, wherever you are in Greater London.

Questions from Nash
Can parking be tricky for a visit in Nash?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Could a tired shower seal in my Nash flat affect the neighbours below?
It can, yes: water that gets past a split bead or cracked grout often runs under the tray and shows on the ceiling below. Replacing the sealant and grout before that happens is much less trouble than repairing a neighbour’s ceiling.
I rent my home. Can I book you?
Yes. Check with your landlord; we can send the quote to them too.
My shower still leaks after a reseal. Can you sort it?
Yes. There’s generally a reason: sealant over sealant, movement or another leak, and we deal with the cause first.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We’ll give you the cure time for the product we used before we leave.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or email us.
Do you work in Nash?
Yes. We work in Nash. To book, call 0345 464 0079 or send us an email.
Can you strip sealant from an acrylic tray safely?
Yes, with care. The old bead is cut and lifted with tools that suit the surface, and the residue is cleaned away. Any existing damage is pointed out before work begins.
Why it’s worth doing now in Nash
A failed seal rarely means a new bathroom. If the bath, tray and tiles are sound, remedial resealing usually puts it right. Where something else has failed, you will hear it from us. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Nash, the repair is bigger than a sealant job.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, ring 0345 464 0079 or email us for an honest opinion and a quote.

Landlord and commercial work in Nash
Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll give you a quote.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
What we do, step by step
There’s no need to move everything out, just the space around the work. 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 Nash, 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.
- First we work out whether the problem is the sealant, movement or a leak.
- 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
- Let us know about earlier repairs to the joints
- Mention any parking rules near the property
- Mention any leaks or damp you’ve noticed

What remedial sealant looks like in Nash
London has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. In a London flat, water from a failed bath or shower seal can reach the neighbours below, which is why it’s worth fixing early.
For landlords with property near Hayes (Kent) station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. As a London address, Nash can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Signs you need remedial sealant in Nash
One of the commonest remedial jobs is sealant on top of sealant. New silicone cannot stick to the old bead, so the new layer peels, and damp and mould settle between them.
Common reasons people contact us include:
- Sealant that came away because the surface wasn’t prepared
- Kitchen joints letting water behind the worktop
- Caulk or the wrong sealant used in a wet area
- Over-sealed joints coming away
For site and facilities teams at buildings such as Wickham Common Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes.

How the job changes by surface
Mouldy bath & shower sealant
Mould often spreads under the bead as well as through it. We treat the exposed joint once the bead is out.
Movement & expansion joints
A sealant stuck to the back of the joint cannot stretch. Backing rod or bond-breaker tape prevents it, letting the sealant flex between the two faces.
How to look after the new joints
Good habits help new joints last longer. Our tips:
- Get the cause of a repeat leak found before resealing
- Don’t wait for a small gap to become a leak
- Never fill a movement joint with mortar or grout
- Run the fan after every shower
Ventilation keeps mould away from the new bead: run the fan during and after showers, or open a window.
Don’t keep resealing the same joint. Get the cause found first, or the next bead will go the same way.
When it is not the sealant
We won’t take on work that won’t last, so these are the limits:
- Movement from fittings that are not supported
- Failed tanking or loose tiles behind the sealant
- Cracks in the fitting rather than the joint
If in doubt, ring 0345 464 0079 or email us and we will say what we think.
