St Pancras Remedial Sealant
Problem with your failed sealant joints in St Pancras? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Leaks that keep coming back after resealing
- Black mould underneath the bead
- Over-sealed joints coming away
The process
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the work takes a few hours for most joints, depending on how much old sealant has to come out for a typical job. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in St Pancras. It helps if you can point us to a visitor permit or a bay close to the door.
- First we find out how and where the joint has failed.
- All the old sealant comes out, including any layers underneath.
- The joint is cleaned, treated for mould and left to dry.
- We use the right backing and sealant for any joint that moves.
- We tool the joint and tell you about anything else that needs attention.
Before we arrive
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Remedial sealant in St Pancras, done properly
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint fails however neatly it’s applied. Out it comes, and in goes a sealant suited to the job. We work on leaking tray & enclosure joints, botched or over-sealed joints and mouldy bath & shower sealant, and common reasons people get in touch are a second bead peeling off the first and sealant peeling off a dusty or damp surface.
Across London, a large share of homes are flats, conversions or mansion blocks, so a bathroom is often directly above a neighbour’s ceiling. In St Pancras, that is a good reason to put tired sealant and grout right early.
A 12-month guarantee comes as standard, so you’re covered after we’ve gone.

How we quote for remedial sealant
We quote each job individually. This is what makes a difference:
- Access and height
- How much there is to do
- The product the joint needs
- Working hours on commercial sites
We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.
What to tell us for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- If it’s domestic, commercial or a hotel
- Pictures of the joints, sent by email
- If someone has resealed it before
- Where the job is, and your postcode
For a quote, ring 0345 464 0079 or send us an email with the location and a short description of the problem. We will give you a clear price before any work starts.
Aftercare tips
To keep the joints looking good and working properly:
- Use a soft cloth, not a scourer, on silicone
- Check ceilings under showers for marks
- Run the fan after every shower
- Deal with small splits early
Give the new sealant its full cure time: follow the cure time we give you.
Movement joints that have split let water into the structure, and left long enough, the edges of the joint can crumble. A joint with sound edges is far easier to reseal.

Remedial sealant around St Pancras
There are hotels and other places to stay in and around St Pancras. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room. 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.
St Pancras is in London, so parking needs planning: let us know about parking bays, permits or a driveway. If you look after a building such as St George the Martyr Church of England Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes. Homes close to Lumen United Reformed Church include some older properties, and walls and floors in older homes can move, and sealant and grout show it first.

Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Surface by surface
Leaking trays & enclosures
Where the joints are the problem, every bead is stripped and resealed with anti-fungal sanitary silicone, including the screen profile and tray edges.
Over-sealed & botched joints
Thick, smeared sealant looks messy and hides problems. Taking it back shows what’s underneath, and then we reseal it neatly.
Common questions in St Pancras
I live in a flat in St Pancras. Can a failed seal leak into the flat 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. It’s far simpler to replace tired sealant early than to deal with a neighbour’s ceiling.
Do you take on hotel work around St Pancras?
Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.
When is the sealant fully cured?
That depends on the sealant used, so follow the cure time we give you when we finish.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
Do you come to St Pancras?
Yes, we do. Our applicators work in St Pancras, and the service is the same as everywhere else.
Can you do several jobs on one visit?
Yes. Several rooms, windows or areas can go on one quote.
Are you insured?
Yes, we are fully insured.
What happens if it’s left?
Stripping out botched sealant adds time to a reseal, but not by much: the work takes a few hours for a typical bath or shower, longer where several layers have been applied. 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.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.
