The process
We bring everything the job needs with us, so you do not need to buy or prepare anything. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours for most joints, depending on how much old sealant has to come out. For a job in Aldgate, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- First we work out whether the problem is the sealant, movement or a leak.
- Each layer is cut out and the residue cleaned off.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Mention any parking rules near the property
- Keep pets and children clear of the area while we work

Advice
Remedial sealant for homes and businesses in Aldgate
A joint that keeps letting you down needs more than another bead. Send pictures when you call 0345 464 0079 or drop us an email, and say how long ago it was last done. We work on failed movement joints, mouldy bath & shower sealant and leaking tray & enclosure joints, and people most often call us about over-sealed joints coming away and a shower that leaks however often it’s resealed.
London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. For a bathroom or kitchen in Aldgate, getting the joints right keeps water where it belongs and the room looking clean.

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.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

What else we do in Aldgate
Aldgate homes and their sealant
London has hard water, so limescale builds up on sealant, grout and fittings. 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.
In the older streets around St James Duke's Place, older homes can move a little, which is hard on rigid grout and tired sealant. If you let a flat or house near London Fenchurch Street station, a joint that keeps failing is best fixed properly while the property is empty.

Aldgate questions
Can parking be tricky for a visit in Aldgate?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
I live in a flat in Aldgate. Can a failed seal leak into the flat below?
Yes, and the first sign is often a stain on the ceiling below. Cutting out the old sealant and laying a new bead early stops it getting that far.
How long does remedial resealing take?
Allow a few hours, depending on how many layers have to come out. You will know the timing when we quote.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
When to call us in Aldgate
Using the wrong product is a common cause: acrylic caulk in a wet area, a general-purpose sealant on a moving joint, or an acetoxy silicone on natural stone or some metals. Each fails in its own way.
Look out for any of the following:
- Over-sealed joints coming away
- Products that weren’t meant for the joint
- Gaps opening along the back of the worktop
- A shower that leaks however often it’s resealed
If you look after a building such as The Aldgate School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
What to look for in a quote
- Whether you can choose the colour
- How hidden problems are handled
- Whether they seal over old material or remove it
- Which sealant they’ll use, and why
What happens if it’s left?
It’s easy to scratch acrylic, enamel or an uPVC frame cutting out old sealant, and any film left behind stops new sealant sticking. Careful removal is most of a remedial job. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Aldgate, the repair is bigger than the sealant job would have been.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

Honest limits
We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Sealant in an older building that needs testing for asbestos first
- Failed tanking or loose tiles behind the sealant
If you are not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer.
