About our remedial sealant in Lissenden Gardens
Remedial work is what we do when sealant has failed or been done badly. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all need stripping out before the joint can be done properly. If you are dealing with smears and lumps from a botched reseal and black mould underneath the bead, we can put it right.
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 Lissenden Gardens are no different.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
How the job changes by surface
Worktops & kitchens
Old kitchen sealant pulls back from the wall over time. It’s cut out, degreased and resealed.
Leaking trays & enclosures
Repeat shower leaks often come from a tray that flexes or an enclosure sealed in the wrong place. Both are checked before we reseal.
Landlord and commercial work in Lissenden Gardens
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
What we’re called out for in Lissenden Gardens
All sealant wears out eventually. Mould grows into the silicone, the surface hardens and the bead shrinks, faster where ventilation is poor. Then the only fix is removal and a new bead.
The most common problems we see are:
- Black mould underneath the bead
- Over-sealed joints coming away
- Worktop sealant that has shrunk and split
- Products that weren’t meant for the joint
If you live in an older home near Highgate Road Chapel, walls and floors in older homes can move, and sealant and grout show it first.

Lissenden Gardens: your questions answered
Could a tired shower seal in my Lissenden Gardens 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.
Is parking an issue for remedial sealant in Lissenden Gardens?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Do you offer different sealant colours?
In most cases you can choose. We will explain which colours are available.
What do you need from me for a quote?
A short description and the location, plus photos if you have them. We will ask anything else we need to know.
Can old silicone be taken off without scratching the tiles?
Yes. Residue is removed with a product suited to the surface rather than scraped hard.
Can tenants book the work?
Of course. Check with your landlord; we can send the quote to them too.
What sealant work can’t fix
Sealant is not the answer to every problem, and we will tell you before any work starts. Sealant won’t put right:
- A cracked shower tray or bath (that needs repair or replacing)
- A tray or worktop that needs refixing first
- Tiles that have come away from the wall
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly.
Surfaces we seal
- Shrunken worktop sealant
- Leaking tray & enclosure joints
- Botched or over-sealed joints
- Mouldy bath & shower sealant
- Failed movement joints
- Expansion joints
How we quote for remedial sealant
The price is agreed before any work begins. It takes into account:
- How easy the joints are to reach
- Whether there’s mould to deal with
- How much old sealant there is and how hard it is to remove
- Which sealant suits the joint
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we’ll go through it with you.
What we need to know
You don’t need to know the technical terms. Just tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- A few photos by email, if you can
- How many joints, rooms or windows are involved
- Access, such as stairs, a lift or height
Asking for a quote is easy: tell us what needs doing and where. Photos by email help us understand the job, and we’ll come back to you with a quote.
How the visit works
At the end, we look at the finished work together and tell you how long to leave it. The visit itself generally takes a few hours for most joints, depending on how much old sealant has to come out, depending on the size of the job. In a London area like Lissenden Gardens, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- 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.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
How to prepare
- Move anything stored near the joints
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any parking rules near the property
