How we handle remedial sealant in Kitts End
A joint that keeps letting you down needs more than another bead. It helps to have photos when you call 0345 464 0079 or email us. We work on expansion joints, shrunken worktop sealant and leaking tray & enclosure joints, and common reasons people get in touch are products that weren’t meant for the joint and sealant that came away because the surface wasn’t prepared.
In much of London, period terraces have been converted into flats over the years, with bathrooms fitted into whatever space was available. Small, steamy rooms are where mould gets into sealant and grout fastest, and homes in Kitts End are no different.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

Kitts End homes and their sealant
London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, which is why it’s worth fixing early. London has hard water, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in.
Managing a site like Monken Hadley CofE Primary School? Then washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes. Homes close to Parish Church of St Mary the Virgin include some older properties, and walls and floors in older homes can move, and sealant and grout show it first.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Ask why a joint failed before redoing it
- Check trays and worktops don’t move
- Don’t wait for a small gap to become a leak
- Use a soft cloth, not a scourer, on silicone
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.
Do not keep resealing the same joint. Have someone find out why, otherwise the next attempt will fail too.
What happens on the day
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. It generally takes a few hours, depending on how many layers have to come out. In Kitts End, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Each layer is cut out and the residue cleaned off.
- We treat any mould and dry the joint thoroughly.
- The right product goes in, with backing where the joint moves.
- We finish neatly and point out anything that needs another trade.
Getting ready for the visit
- Mention if the joints have been sealed before
- Tell us about any water getting in
- Tell us about access, such as stairs, a lift or high-level joints

Advice
When to call us in Kitts End
All sealant wears out eventually. Mould grows into the silicone, the surface hardens and the bead shrinks, especially in damp, poorly aired rooms. Then the only fix is removal and a new bead.
The problems people usually mention when they call include:
- A second bead peeling off the first
- Kitchen joints letting water behind the worktop
- Leaks that keep coming back after resealing
- Floor or wall movement joints that have failed
As a London address, Kitts End can be tricky for parking: let us know about parking bays, permits or a driveway.
What your quote should include
- What happens if the job turns out different
- Whether they’re fully insured
- Whether all the old sealant comes out first
- What preparation is included
Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Why it’s worth doing now in Kitts End
Mould under a bead cannot be reached by cleaning. The layers have to come out, and the joint treated and dried before resealing. 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 reflects the work involved, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.

Your questions about remedial sealant in Kitts End
Could a tired shower seal in my Kitts End flat affect the neighbours 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 work for landlords with property near Hadley Wood station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.
How long will it take to strip and reseal the joint?
Longer than a simple reseal, because every layer has to come out. For most joints, it’s a few hours.
Can you remove old sealant without damaging the bath?
Yes. Careful removal is most of a remedial job, particularly on softer surfaces like acrylic.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do you offer different sealant colours?
In most cases you can choose. We will tell you which colours the right product comes in.
Do you have insurance?
Yes. Mr Mastic is fully insured.
When it is not the sealant
A few problems are outside what sealant work can do:
- Movement from fittings that are not supported
- A cracked shower tray or bath (that needs repair or replacing)
- A leaking trap, valve or supply pipe
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think.
