About our remedial sealant in Kennington
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint will not last, however tidy it looks. Out it comes, and in goes a sealant suited to the job. Typical jobs include worktop sealant that has shrunk and split and products that weren’t meant for the joint, across expansion joints, leaking tray & enclosure joints and shrunken worktop sealant.
Hard London water leaves limescale on sealant, grout and taps alike. In Kennington, remedial sealant is as much about a room looking cared for as about keeping water out.
There’s a 12-month guarantee on every job, large or small.

What affects the cost of remedial sealant
We do not publish a price list. What we look at:
- Whether there’s mould to deal with
- How many rooms, windows or areas are involved
- Which sealant suits the joint
- How much there is to do
What you pay reflects the work, not guesswork. That’s why we ask about the job first and give you a clear quote before work begins.
What we need to know
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- The type of property
- A few photos by email, if you can
- The problem you’ve noticed
- Any access issues, like height or stairs
To get a quote, phone 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. You will have a clear quote before we start.
When it is not the sealant
To be straight with you, some problems need a different trade:

- Movement from fittings that are not supported
- Plumbing leaks behind walls or under trays
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly before booking.

Remedial sealant in Kennington: local notes
In a London flat, water from a failed bath or shower seal can reach the neighbours below, which is why it’s worth fixing early. London’s water is hard, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in.
Homes close to Calvary Church of God in Christ include some older properties, and walls and floors in older homes can move, and sealant and grout show it first. Rented homes near Vauxhall station change hands often, and a joint that keeps failing is best fixed properly while the property is empty. If you look after a building such as St Stephen's Church of England Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes.
Kennington is about 2 miles south-west of London, in Greater London. Homes, rented property, offices and hotels in Kennington can book us for remedial sealant. The work is guaranteed for a year. Kennington is one of 764 places in Greater London we cover.
Work in SW8, SW1P and SE11 is quoted and booked the same way as anywhere else. If you need remedial sealant at a property on Kay Road, Lett Road and Rita Road or anywhere close by, we can help.

How the visit works
You don’t need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for most joints, depending on how much old sealant has to come out for a typical job. In Kennington, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- We protect the surfaces around the joint.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- Once dry, a suitable sealant is applied and tooled.
- We give you the cure time and explain what caused the failure.
Preparing for the visit
- Move anything stored near the joints
- Tell us about any water getting in
- Where the joints are inside, avoid wetting them before we arrive

Advice
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Surface by surface
Movement & expansion joints
Movement joints in floors, walls and façades need a flexible sealant set to the right depth. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed.
Mouldy bath & shower sealant
Repeat mould usually points to a damp, poorly aired room. Along with resealing, we’ll mention if the room needs better ventilation.
Kennington questions
Is parking an issue for remedial sealant in Kennington?
Parking in Kennington, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
I let a flat near Vauxhall station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
How long does the work take?
The number of joints and layers decides it. We’ll tell you before any work starts.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. Indoors, that generally means someone at home.
What does remedial sealant cost?
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.
Do you offer different sealant colours?
Most of the time, yes. We’ll tell you which colours the right product comes in.
Are you insured?
Yes. We’re fully insured for every job we do.
Can failed expansion joints be resealed?
Yes. If a joint has been filled with mortar or rigid filler, we rake it out where possible, then the joint is sealed properly.

Why act early in Kennington
A joint that has failed twice will fail again unless the cause is dealt with. Taking time to find the cause, whether it’s movement, a leak or the wrong product, is what stops it happening again. 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.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Why us?
- White, clear, grey or another colour, product permitting
- We leave the area clean and tidy
- Every job guaranteed for a year
- More than 20 years in sealant work
