Remedial sealant in Camden Town, done properly
Removing failed sealant is the hardest part of the job. We cut out every layer, clear the residue and degrease the surfaces, without scratching tiles, trays or frames. New sealant only bonds to a clean, dry joint. If you have floor or wall movement joints that have failed and leaks that keep coming back after resealing, we can help.
In much of London, period terraces have been converted into flats over the years, and bathrooms were often squeezed into small rooms. Small, steamy rooms are where mould gets into sealant and grout fastest, and homes in Camden Town are no different.
Big or small, it’s backed by our one-year guarantee.

Common questions in Camden Town
Do you work for landlords with property near Camden Road station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.
Could a tired shower seal in my Camden Town 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.
Can you fix a reseal that hasn’t worked?
Yes. First we check whether the leak is the sealant at all, then strip and reseal the joints.
Is there any odour?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
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.
What if resealing will not fix my leak?
We check for that before we reseal. If we find the leak is elsewhere, we tell you before going further.
Are you insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
How to look after the new joints
Looking after new joints is easy:
- Deal with small splits early
- Clean sealant with mild products only
- Look for stains below bathrooms now and then
- Ask why a joint failed before redoing it
Clean gently: a mild cleaner and a soft cloth, with no blades or scourers.
Movement joints that have split let water into the structure, and the longer it’s left, the more the joint edges break down. Resealing while the edges are sound is simpler.
When it isn’t the sealant
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
- Sealant in an older building that needs testing for asbestos first
- Tiles that have come away from the wall
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think before booking.

Remedial sealant in Camden Town: local notes
Camden Town has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and 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.
As a London address, Camden Town can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. Rented homes near Camden Road station change hands often, and a joint that keeps failing is best fixed properly while the property is empty.
Camden Town is about 2 miles north of City of Westminster, in Greater London. Wherever you are in the NW1 postcode area, we can carry out remedial sealant at your property. We cover 764 towns and villages across Greater London.

Why it’s worth doing now in Camden Town
Adding more sealant is the usual quick fix, and it rarely works. It doesn’t grip the old layer, leaving the leak in place and one more layer to cut out later. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Camden Town, the repair is bigger than the sealant job would have been.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.

Common problems we fix in Camden Town
Sealant needs a clean, dry surface with no grease on it. Soap film, dust, damp or old residue stop it gripping, and the joint starts to come away early.
If you can see any of these, it’s time to have the joints looked at:
- Repeat leaks from the same joint
- Wide, uneven beads that look worse than the old ones
- Sealant peeling off a dusty or damp surface
- Decorators’ caulk around a bath or shower
If you live in an older home near St Michael's Church, walls and floors in older homes can move, and sealant and grout show it first.
