Sealant is not the answer to every problem, and we will tell you before any work starts. It will not solve:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- A tray or bath that’s cracked
- A leaking trap, valve or supply pipe
If you are not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer.
Joints and surfaces we work on
- Leaking tray & enclosure joints
- Mouldy bath & shower sealant
- Expansion joints
- Botched or over-sealed joints
- Failed movement joints
- Shrunken worktop sealant
Remedial sealant in Kennington, done properly
Some sealant jobs aren’t a simple reseal, because someone has already had a go. New sealant over old, smeared beads, unsuitable products and hidden mould all have to come out before the joint can be done properly. Common call-outs are for kitchen joints letting water behind the worktop and floor or wall movement joints that have failed, across botched or over-sealed joints, mouldy bath & shower sealant and shrunken worktop sealant.
Homes around Kennington range from older cottages to more recent houses. Older homes can move a little with the seasons, which is hard on tired sealant and rigid grout.
All our work is covered by our one-year guarantee.

Remedial sealant around Kennington
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings. Kennington has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and can be done room by room.
For site and facilities teams at buildings such as St Swithun's CofE Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

What affects the quote in Kennington
Some jobs are bigger than they look, and some smaller. The main factors:
- How much old sealant there is and how hard it is to remove
- The product the joint needs
- Working hours on commercial sites
- Mould in or behind the old joints
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, ring 0345 464 0079 or send us an email for an honest opinion and a quote.
Helping us quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- How many joints, rooms or windows are involved
- Whether it has been sealed before
- Whether it’s a home or a business
- What the problem is, such as mould, gaps, leaks or cracking
We quote each job on its own, so start by telling us what you need. Simply phone 0345 464 0079 or email us and describe the job.
How the visit works
We keep the work tidy and contained to the joints we’re treating, so you can carry on as normal. Expect the work to take a few hours for most joints, depending on how much old sealant has to come out, and we explain the cure time before we leave. A visit to Kennington is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- The right product goes in, with backing where the joint moves.
- We finish neatly and point out anything that needs another trade.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Let us know about earlier repairs to the joints
- Let us know about stairs, lifts or work at height

Related advice
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Don’t add new sealant on top of old
- Use a soft cloth, not a scourer, on silicone
- Keep movement joints clear of mortar and paint
- Ask why a joint failed before redoing it
Clean gently: no scraping, scouring pads or harsh chemicals.
Movement joints that have split let water into the structure, and the longer it’s left, the more the joint edges break down. Resealing while the edges are sound is simpler.
Kennington: your questions answered
Can you help a landlord with a rental near Radley station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear quote.
Is Kennington within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
How long should I leave it?
Different products cure at different speeds, so follow the cure time we give you.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Can failed expansion joints be resealed?
Yes. The depth is set with backing so the sealant only bonds to the two sides.
Are you insured?
Yes. We’re fully insured, and we’ve been doing sealant work for more than 20 years.
Do you do commercial work?
Yes. We’ve worked for hotels, offices and other businesses and we’re fully insured.
Places near Kennington
Also in Kennington
Different surfaces, different methods
Over-sealed & botched joints
Botched joints sometimes have damaged edges from earlier scraping. We take care not to make it worse, and point out any existing damage.
Worktops & kitchens
Old kitchen sealant pulls back from the wall over time. We strip it, degrease the joint and reseal in a colour to suit.
What we’re called out for in Kennington
A lot of failed joints have been sealed over rather than replaced. Silicone doesn’t bond to silicone, so the new layer peels, and damp and mould settle between them.
Signs it’s time to call us include:
- Kitchen joints letting water behind the worktop
- Beads that never stuck properly
- Leaks that keep coming back after resealing
- Floor or wall movement joints that have failed
For an older house near a landmark such as St Swithun's Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them.
What your quote should include
- What the cure time is
- How the colour is chosen
- How much experience the applicator has
- Whether they seal over old material or remove it
