Remedial sealant in South Kensington, done properly
In South Kensington, as anywhere, remedial jobs tend to look alike: sealant over sealant, mould under the bead, leaks that come back and movement joints that have split. We strip each one back and start from scratch. We work on mouldy bath & shower sealant, shrunken worktop sealant and botched or over-sealed joints, and common reasons people get in touch are leaks that keep coming back after resealing and floor or wall movement joints that have failed.
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.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Remedial sealant around South Kensington
There are hotels and other places to stay in and around South Kensington. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room. London’s water is hard, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
In the older streets around Chapel of St Luke, walls and floors in older homes can move, and sealant and grout show it first. For landlords with property near West Brompton station, botched sealant from a previous quick fix is easier to strip out between tenants. Schools such as Our Lady of Victories RC 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.

How the visit works
We bring everything the job needs with us. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours, depending on how many layers have to come out. In a London area like South Kensington, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.
- 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.
Before we arrive
- Mention any tricky access
- Mention any parking rules near the property
- Keep children and pets away from the work area

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
FAQs for South Kensington
Is parking an issue for remedial sealant in South Kensington?
Parking in South Kensington, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Can worn sealant in a flat in South Kensington cause a leak downstairs?
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 have insurance?
Yes. We’re fully insured, and we’ve been doing sealant work for more than 20 years.
Can you match the sealant colour?
Normally, yes. Sealants come in white, clear, grey and other colours, and we will agree it with you first.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
What do you need from me for a quote?
Tell us what needs doing and where, plus pictures if you have them. We will ask anything else we need to know.
Landlord and commercial work in South Kensington
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll quote.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Why act early in South Kensington
A failed seal rarely means a new bathroom. If the bath, tray and tiles are sound, remedial resealing usually puts it right. Where something else has failed, you’ll hear it from us. In a flat in South Kensington, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.
Why us?
- Any old sealant cut out fully, not covered over
- Arbo and Everbuild products
- Colour agreed with you before we start
- More than 20 years in sealant work

Surface by surface
Over-sealed & botched joints
Previous removal attempts can leave scratches or gouges. We take care not to make it worse, and tell you about any damage we find.
Movement & expansion joints
A movement joint must be able to stretch. We remove the failed sealant, fit backing and reseal with a low-modulus product.
What we can’t put right
Sealant is not the answer to every problem, and we’ll tell you before any work starts. Sealant will not put right:
- Failed tanking or loose tiles behind the sealant
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- A cracked shower tray or bath (that needs repair or replacing)
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly.
