When something else is needed
New sealant can’t fix everything, and we’ll tell you before we start. It will not solve:
- A bath, tray or worktop that moves until it’s properly fixed
- A cracked shower tray or bath (that needs repair or replacing)
- Water damage behind tiles that needs a tiler

About our remedial sealant in Willesden
If a joint has been resealed and is leaking again, it’s worth a proper look. Send pictures when you phone 0345 464 0079 or drop us an email, and say how long ago it was last done. If you have floor or wall movement joints that have failed and wide, uneven beads that look worse than the old ones, we can help, whatever the surface.
Hard London water leaves limescale on sealant, grout and taps alike. For a bathroom or kitchen in Willesden, getting the joints right keeps water where it belongs and the room looking clean.

When to call us in Willesden
Joints that move need sealant that can stretch. Flexing baths, rocking trays and building movement joints split any bead that’s too stiff or too thin.
Keep an eye out for these signs:
- Worktop sealant that has shrunk and split
- Thick, messy sealant smeared over tiles
- Movement joints that have split or pulled away
- Repeat leaks from the same joint
Schools such as St Andrew and St Francis CofE Primary School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes.
What your quote should include
- How the joint is cleaned and prepared
- Whether VAT is included
- The length of the guarantee
- What the cure time is
Questions from Willesden
I let a flat near Kensal Rise station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Could a tired shower seal in my Willesden 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. Cutting out the old sealant and laying a new bead early stops it getting that far.
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.
Do you work in Willesden?
Yes. We work in Willesden and the rest of Greater London. For a quote, call 0345 464 0079 or drop us an email.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Can you take off two layers of silicone?
Yes. We cut out all the layers and clean off the film, then the joint is resealed once.
My shower still leaks after a reseal. Can you sort it?
Yes. Repeat leaks usually come from over-sealing, movement or water getting in elsewhere, so we find that first.
Can you reseal a split movement joint?
Yes. Failed movement joints are cut out and resealed with backing and a flexible sealant suited to the movement.
Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Can I do it myself?
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

What we do, step by step
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a typical bath or shower, longer where several layers have been applied. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Willesden. It helps if you can point us to a visitor permit or a bay close to the door.
- We protect the surfaces around the joint.
- Every layer of failed sealant is stripped out.

Willesden has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.
In the older streets around Church of St Andrew, timber floors under older bathrooms flex, so joints need a sealant that moves with them. Willesden is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Different surfaces, different methods
Movement & expansion joints
A sealant stuck to the back of the joint cannot stretch. Backing stops that, letting the sealant flex between the two faces.
Mouldy bath & shower sealant
Black mould inside the bead will not scrub out. All of it comes out, and the joint is treated and dried ahead of a new anti-fungal bead.
