About our remedial sealant in Highbury
In Highbury, as anywhere, remedial jobs tend to look alike: over-sealed joints, hidden mould, repeat leaks and split movement joints. Each is stripped back and done again properly. Typical jobs include repeat leaks from the same joint and products that weren’t meant for the joint, across botched or over-sealed joints, leaking tray & enclosure joints and shrunken worktop sealant.
Much of London’s older housing is Victorian and Edwardian terraces, many of them now split into flats, and bathrooms were often squeezed into small rooms. Small, steamy rooms are where mould gets into sealant and grout fastest, and homes in Highbury are no different.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Common questions in Highbury
I live in a flat in Highbury. Can a failed seal leak into the flat 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.
Do you work for landlords with property near Canonbury station?
Yes, we work for letting agents and landlords. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before work begins.
How much does remedial sealant cost in Highbury?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before any work starts.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.
Can you fix a reseal that hasn’t worked?
Yes. There’s normally a reason: sealant over sealant, movement or another leak, and we deal with the cause first.
Can you quote for more than one area?
Yes. Several rooms, windows or areas can go on one quote.
Do you come to Highbury?
Yes. We work in Highbury. To book, ring 0345 464 0079 or email us.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Don’t add new sealant on top of old
- Deal with small splits early
- Run the fan after every shower
- Look for stains below bathrooms now and then
Ventilation keeps mould away from the new bead: use the extractor or open a window after showering.
Mould under a second layer of sealant keeps growing out of sight. When it finally shows, the whole bead needs to come out.
Remedial sealant around Highbury
Highbury 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’s water is hard, which leaves limescale on sealant, grout and taps.
In the older streets around Christ Church, older homes can move a little, which is hard on rigid grout and tired sealant. Rented homes near Canonbury station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

What happens on the day
When we get to you, 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 most joints, depending on how much old sealant has to come out. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Highbury. It helps if you can point us to a visitor permit or a bay close to the door.
- First we work out whether the problem is the sealant, movement or a leak.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you’re told about anything else we found.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Let us know about parking restrictions
- Let us know about stairs, lifts or work at height

Work for landlords, hotels and businesses
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
What we can’t put right
In fairness, some problems need a different trade:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- A bath, tray or worktop that moves until it’s properly fixed
- Failed tanking or loose tiles behind the sealant
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think before you book.
Joints and surfaces we work on
- Botched or over-sealed joints
- Expansion joints
- Mouldy bath & shower sealant
- Failed movement joints
- Shrunken worktop sealant
- Leaking tray & enclosure joints

What else we do in Highbury
Surface by surface
Over-sealed & botched joints
A botched joint can hide two or three layers of sealant, and silicone residue is cleaned off the tiles too. Only a clean joint will take a new bead.
Movement & expansion joints
Bonding on three sides is a common reason movement joints tear. Backing rod or bond-breaker tape prevents it, letting the sealant flex between the two faces.
Why it’s worth doing now in Highbury
Leaks that are left keep doing damage out of sight: wet floors, stained ceilings and swollen worktops. Dealing with the joint now is a small job by comparison. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in Highbury.
Doing several joints on one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll give you a clear price for the lot.
What you get with us
- Every job guaranteed for a year
- An ARBOMaster approved applicator
- Trusted Arbo and Everbuild sealants
- Any old sealant cut out fully, not covered over
Do you need remedial sealant in Highbury?
Silicone only bonds to surfaces that are clean and dry. Soap film, dust, damp or old residue stop it gripping, and the joint starts to come away early.
It’s worth asking for a quote if you see:
- Gaps opening along the back of the worktop
- Thick, messy sealant smeared over tiles
- Repeat leaks from the same joint
- Black mould underneath the bead
Highbury is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
