Your questions about remedial sealant in London Docklands
Do you work for landlords with property near Canary Wharf station?
Yes. We work for letting agents and landlords as well as householders. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Can worn sealant in a flat in London Docklands cause a leak downstairs?
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.
Where are you based?
Our base is Crawley. Our area covers South East England, London and Scotland.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Can I choose the sealant colour?
In most cases you can choose. We will tell you which colours the right product comes in and agree one before we start.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Does remedial work come with a guarantee?
Yes. You get our 12-month guarantee, and we’re fully insured.
About our remedial sealant in London Docklands
If a joint has been resealed and is leaking again, it’s worth a proper look. Send photos when you phone 0345 464 0079 or drop us an email, and say how long ago it was last done. If you have caulk or the wrong sealant used in a wet area and floor or wall movement joints that have failed, we can put it right, whatever the surface.
Across London, a large share of homes are flats, conversions or mansion blocks, so a bathroom is often directly above a neighbour’s ceiling. That makes worn sealant and cracked grout in London Docklands more than a cosmetic job.
A one-year guarantee comes as standard, so you are covered after we’ve gone.

What we can’t put right
Some problems need a builder, plumber or other trade rather than us:
- A cracked shower tray or bath (that needs repair or replacing)
- Tiles that have come away from the wall
- Movement from fittings that aren’t supported
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer.
Where we work in London Docklands
- Failed movement joints
- Shrunken worktop sealant
- Leaking tray & enclosure joints
- Mouldy bath & shower sealant
- Expansion joints
- Botched or over-sealed joints
Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What happens on the day
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for most joints, depending on how much old sealant has to come out. For a job in London Docklands, parking and access are the things to plan: let us know about parking, the floor we will be working on and any lift or shared entrance.
- Surrounding tiles, trays and frames are protected first.
- The botched or failed sealant is cut away completely.
- The joint is degreased and checked for movement and leaks.
- New sealant goes in once the joint is dry, and is tooled smooth.
- You get the cure time and our view on why the joint failed.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Tell us about any water getting in
- Try not to wet indoor joints just before the visit

Why it’s worth doing now in London Docklands
A joint that has failed twice will fail again unless the cause is dealt with. Finding it, whether movement, water from elsewhere or an unsuitable product, ends the cycle. In a flat in London Docklands, 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.
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.

Different surfaces, different methods
Windows & doors
Smeared or badly matched mastic can be cut out and redone neatly, in a colour that suits the frame.
Over-sealed & botched joints
Thick, smeared sealant looks messy and hides problems. Taking it back shows what’s underneath.
Landlord and commercial work in London Docklands
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
Signs you need remedial sealant in London Docklands
Joint depth matters. A bead bonded on three sides, or laid too thick, can’t flex, so it tears when the joint moves. Backing rod or bond-breaker tape prevents it.
These are the problems we are asked about most:
- Worktop sealant that has shrunk and split
- Mould trapped under a layer of silicone
- Torn expansion joints
- Decorators’ caulk around a bath or shower
In the older streets around St Peter's Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them.
