It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. Whenever you’re ready, ring 0345 464 0079 or send us an email.
About our remedial sealant in Walworth
Some sealant jobs aren’t a simple reseal, because someone has already had a go. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all need stripping out before the joint can be done properly. If you are dealing with thick, messy sealant smeared over tiles and a second bead peeling off the first, we can put it right.
London homes include a lot of flats, conversions and mansion blocks, so a bathroom is often directly above a neighbour’s ceiling. In Walworth, that’s a good reason to put tired sealant and grout right early.
All of our work is guaranteed for twelve months, in Walworth and everywhere else we cover.

Work for landlords, hotels and businesses
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we’ll give you a quote.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Common problems we fix in Walworth
Silicone only bonds to surfaces that are clean and dry. Residue, moisture or dust left in the joint weaken the bond, and the joint starts to come away early.
Common reasons people contact us are:
- Sealant that came away because the surface wasn’t prepared
- Gaps opening along the back of the worktop
- Over-sealed joints coming away
- Dark patches showing through the sealant
For an older house near a landmark such as Lady Margaret Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

What the job involves on each surface
Windows & doors
Smeared or badly matched mastic can be cut out and redone neatly, matched to the frame colour.
Movement & expansion joints
Some movement joints have been filled with mortar or grout. Where it can be raked out, we replace it with flexible sealant.
Questions from Walworth
Can worn sealant in a flat in Walworth cause a leak downstairs?
Yes, it can. Water that gets past failed sealant or cracked grout can run under the bath or tray and show up on the ceiling below. It’s far simpler to replace tired sealant early than to deal with a neighbour’s ceiling.
Do you take on hotel work around Walworth?
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.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Where are you based?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Do you remove the old sealant?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Can you quote for more than one area?
Yes. Just list everything you need and you’ll get one quote.
How much does remedial sealant cost in Walworth?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
What remedial sealant looks like in Walworth
Walworth has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and can be done room by room. 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.
Walworth is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. If you let a flat or house near Elephant & Castle station, a joint that keeps failing is best fixed properly while the property is empty.

How it works
The work is kept neat and contained to the joints we’re treating, so you can get on with your day. Expect the work to take a few hours for a typical bath or shower, longer where several layers have been applied. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- Surrounding tiles, trays and frames are protected first.
- The botched or failed sealant is cut away completely.
- We clean and degrease the joint and look for signs of movement or water.
- Once dry, a suitable sealant is applied and tooled.
- We give you the cure time and explain what caused the failure.
How to prepare
- Move anything stored near the joints
- Mention any sign-in or site rules at work premises
- Tell us about access, such as stairs, a lift or high-level joints

Why it’s worth doing now in Walworth
DIY removal often leaves scratches and a film of residue, and any film left behind stops new sealant sticking. Careful removal is most of a remedial job. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
The cost depends on how much there is to do, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts.
Why us?
- Over 20 years’ experience
- Tidy, careful work
- A choice of colours where the product allows
- Anti-fungal silicone where joints get wet
