What we do, step by step
At the end, we look at the finished work together and tell you how long to leave it. The visit itself normally takes a few hours for a typical bath or shower, longer where several layers have been applied, depending on the size of the job. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- Surrounding tiles, trays and frames are protected first.
- The botched or failed sealant is cut away completely.
- The joint is degreased and checked for movement and leaks.
- Once dry, a suitable sealant is applied and tooled.
- You get the cure time and our view on why the joint failed.
Before we arrive
- Mention any parking rules near the property
- Tell us about any water getting in
- Clear items away from the joints we’re working on

Advice
Arnos Grove: your questions answered
Can you help a landlord with a rental near New Southgate station?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
I live in a flat in Arnos Grove. Can a failed seal leak into the flat below?
Yes, it can. Water that gets past failed sealant or cracked grout can run under the bath or tray and show up on the ceiling below. It’s far simpler to replace tired sealant early than to deal with a neighbour’s ceiling.
How much does remedial sealant cost in Arnos Grove?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we will talk you through it.
How long does the work take?
That depends on how many layers there are and how many joints. We’ll tell you before any work starts.
Is there any odour?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Do you fix expansion and movement joints?
Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.
Does remedial work come with a guarantee?
Yes. Our one-year guarantee covers the work.
Can you remove sealant that’s been put over old sealant?
Yes. Each layer is cut out and the residue cleaned off, before resealing with a single bead.

Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Do not wait for a small gap to become a leak
- Keep an eye on the ceiling below the bathroom
- Get the cause of a repeat leak found before resealing
- Run the fan after every shower
Give the new sealant its full cure time: usually around 24 hours, or as long as we advise.
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 in Arnos Grove: local notes
London’s water is hard, so limescale builds up on sealant, grout and fittings. 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.
In the older streets around Syro-Malabar Catholic Church of London, timber floors under older bathrooms flex, so joints need a sealant that moves with them. As a London address, Arnos Grove can be tricky for parking: let us know about parking bays, permits or a driveway.

Why deal with it now?
Leaks that are left keep doing damage out of sight: soaked floorboards, ceiling stains below and blown plaster. By comparison, sorting the joint is quick. 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 Arnos Grove, the repair is bigger than the sealant job would have been.
What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts.

What the job involves on each surface
Worktops & kitchens
Old kitchen sealant pulls back from the wall over time. It’s cut out, degreased and resealed.
Movement & expansion joints
A movement joint must be able to stretch. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed.
How we quote for remedial sealant
We don’t publish a price list, because jobs vary so much. What we look at:
- Any mould that needs treating
- The amount of work
- How many rooms, windows or areas are involved
- The old material and how stubborn it is
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and give you a clear price before any work starts.
Helping us quote
When you call or email, these details help:
- How many joints, rooms or windows are involved

Common problems we fix in Arnos Grove
A lot of failed joints have been sealed over rather than replaced. New silicone can’t stick to the old bead, so the top layer lifts and water and mould collect between the two.
People usually contact us when they notice something like this:
- Smears and lumps from a botched reseal
- Torn expansion joints
- Repeat leaks from the same joint
- Sealant peeling off a dusty or damp surface
Schools such as Bowes Primary School are buildings too, and 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.
What to look for in a quote
- How the joint is cleaned and prepared
- The length of the guarantee
- How much experience the applicator has
- Is the old sealant removed completely?
