Chelsea Harbour Remedial Sealant
Removing failed, mouldy or leaking sealant and putting it right for homes and businesses in Chelsea Harbour and across Greater London. Fully insured, ARBOMaster approved and guaranteed for a year.
- Torn expansion joints
- Caulk or the wrong sealant used in a wet area
- Repeat leaks from the same joint
Remedial sealant for homes and businesses in Chelsea Harbour
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint fails however neatly it’s applied. We take it out and use a sealant made for that joint. If you have a shower that leaks however often it’s resealed and mould trapped under a layer of silicone, we can put it right, whatever the surface.
London homes include a lot of flats, conversions and mansion blocks, and many bathrooms sit right above someone else’s ceiling. That makes worn sealant and cracked grout in Chelsea Harbour more than a cosmetic job.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

When something else is needed
Sealant isn’t the answer to every problem, and we will tell you before we start. It won’t solve:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- Water damage behind tiles that needs a tiler
- A cracked shower tray or bath (that needs repair or replacing)
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think before booking.
Surfaces we seal
- Shrunken worktop sealant
- Leaking tray & enclosure joints
- Failed movement joints
- Mouldy bath & shower sealant
- Expansion joints
- Botched or over-sealed joints
Bathrooms and kitchens in Chelsea Harbour
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. There are hotels and other places to stay in and around Chelsea Harbour. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.
If you look after a building such as Chelsea Academy, we reseal washrooms and kitchens in schools and businesses as well as homes. Letting a property close to Imperial Wharf station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

How it works
You don’t need to clear the whole room or building, only the area right around the joints. We protect the rest, and the work takes a few hours for most joints, depending on how much old sealant has to come out in most cases. For a job in Chelsea Harbour, parking and access are the things to plan: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- We look at how the sealant has failed and check for movement or a leak path.
- All the old sealant comes out, including any layers underneath.
- The joint is cleaned, treated for mould and left to dry.
- We use the right backing and sealant for any joint that moves.
- We tool the joint and tell you about anything else that needs attention.
Preparing for the visit
- Tell us about any water getting in
- Mention any sign-in or site rules at work premises
- Tell us if parking is tricky

What the job involves on each surface
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.
Movement & expansion joints
Some movement joints have been filled with mortar or grout. Where it can be raked out, we replace it with flexible sealant.
Your questions about remedial sealant in Chelsea Harbour
Do you work for landlords with property near Imperial Wharf station?
Yes. We work for landlords and letting agents as well as homeowners. Just call 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear price.
Is parking a problem for a job in Chelsea Harbour?
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.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Can you fix a reseal that hasn’t worked?
Yes. Repeat leaks usually come from over-sealing, movement or water getting in elsewhere, and we deal with the cause first.
Is remedial work guaranteed?
Yes. Every job comes with our one-year guarantee.
Do you fix expansion and movement joints?
Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures.
What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We will tell you what we are using and why.
Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
When to call us in Chelsea Harbour
A lot of failed joints have been sealed over rather than replaced. Silicone does not bond to silicone, so the top layer lifts and water and mould collect between the two.
Look out for these signs:
- Floor or wall movement joints that have failed
- Kitchen joints letting water behind the worktop
- Smears and lumps from a botched reseal
- Sealant that came away because the surface wasn’t prepared
Homes close to St Mary's Church include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant.
Before booking anyone
- Whether all the old sealant comes out first
- Is VAT in the price?
- When the joint can take water or movement
- Whether you can choose the colour
Why deal with it now?
Leaks that are left keep doing damage out of sight: wet floors, stained ceilings and swollen worktops. By comparison, sorting the joint is quick. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and agree the price before starting.
Why us?
- We’re fully insured
- A choice of colours where the product allows
- We leave the area clean and tidy
- Homes, businesses and hotels
Aftercare tips
Good habits help new joints last longer. A few tips:
- Act on a lifting corner straight away
- Keep the room well ventilated
- Get the cause of a repeat leak found before resealing
- Don’t add new sealant on top of old
Leave the new joint to cure fully before it gets wet or moves: generally around 24 hours, or as long as we advise.
Do not keep resealing the same joint. Get the cause found first, otherwise the next attempt will fail too.
