Remedial sealant in Soho
Getting old sealant out properly is slow, careful work. We cut out every layer, clear the residue and degrease the surfaces, taking care not to scratch the surfaces around it. Only then can new sealant bond. Common call-outs are for over-sealed joints coming away and wide, uneven beads that look worse than the old ones, on botched or over-sealed joints, leaking tray & enclosure joints and shrunken worktop sealant.
London homes include a lot of flats, conversions and mansion blocks, so a bathroom is often directly above a neighbour’s ceiling. In Soho, that is a good reason to put tired sealant and grout right early.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

How the job changes by surface
Leaking trays & enclosures
Where the joints are the problem, every bead is stripped and resealed with anti-fungal sanitary silicone, tray edges and screen profiles included.
Movement & expansion joints
A movement joint must be able to stretch. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed.
Why it’s worth doing now in Soho
Hidden water does the most damage: soaked floorboards, ceiling stains below and blown plaster. By comparison, sorting the joint is quick. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble.
Doing several joints on one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
What you get with us
- An ARBOMaster approved applicator
- We leave the area clean and tidy
- Full insurance on every job
- Anti-fungal sanitary silicone in wet areas
What remedial sealant looks like in Soho
There are hotels and other places to stay in and around Soho. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room. 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.
For site and facilities teams at buildings such as Soho Parish CofE Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes. Soho is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

FAQs for Soho
I let a flat near Tottenham Court Road station. Can you help?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
I live in a flat in Soho. Can a failed seal leak into the flat below?
Yes, and the first sign is often a stain on the ceiling below. Cutting out the old sealant and laying a new bead early stops it getting that far.
Do you take out the old sealant first?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
When is the sealant fully cured?
Different products cure at different speeds, so please follow the time we give you when we finish.
Can I choose the sealant colour?
Yes. White, clear and grey are common, and other colours are available for many products, and we will agree it with you first.
What does remedial sealant cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Can failed expansion joints be resealed?
Yes. The depth is set with backing so the sealant only bonds to the two sides.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. Indoors, that normally means someone at home.

Aftercare tips
A little care helps the new joints last. Our advice:
- Air the bathroom so the sealant can dry
- Don’t point over movement joints
- Check ceilings under showers for marks
- Deal with small splits early
If we’ve found a cause, such as a loose tray or a leaking waste, get it fixed, or the new joint may fail again.
Mould trapped under over-sealed joints spreads unseen. By the time it shows through, the joint is well past saving.
What we do, step by step
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes a few hours for most joints, depending on how much old sealant has to come out, depending on the size of the job. For a job in Soho, parking and access are the things to plan: let us know about parking, the floor we will be working on and any lift or shared entrance.
- We protect the surfaces around the joint.
- The botched or failed sealant is cut away completely.
- The joint is degreased and checked for movement and leaks.
- Once dry, a suitable sealant is applied and tooled.
- We give you the cure time and explain what caused the failure.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Let us know about earlier repairs to the joints
- Mention any tricky access

Advice
When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- A bath, tray or worktop that moves until it’s properly fixed
- Plumbing leaks behind walls or under trays
- Failed tanking or loose tiles behind the sealant
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think.
What we seal
- Leaking tray & enclosure joints
- Expansion joints
- Mouldy bath & shower sealant

Landlord and commercial work in Soho
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
When to call us in Soho
Even good sealant ages. Mould grows into the silicone, the surface hardens and the bead shrinks, faster where ventilation is poor. At that point it has to come out.
The most common problems we see are:
- Over-sealed joints coming away
- Thick, messy sealant smeared over tiles
- Mould trapped under a layer of silicone
- Gaps opening along the back of the worktop
If you live in an older home near St Anne's Church, older homes can move a little, which is hard on rigid grout and tired sealant.
