Remedial sealant & repairs in Cranham, Greater London
Failed sealant joints in Cranham need attention? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Repeat leaks from the same joint
- Wide, uneven beads that look worse than the old ones
- Caulk or the wrong sealant used in a wet area
Remedial sealant in Cranham, done properly
Getting old sealant out properly is slow, careful work. Every layer is cut out, the residue cleaned off and the joint degreased, taking care not to scratch the surfaces around it. Only then can new sealant bond. If you are dealing with mould trapped under a layer of silicone and products that weren’t meant for the joint, we can put it right, on expansion joints, botched or over-sealed joints and mouldy bath & shower sealant alike.
Across London, a large share of homes are flats, conversions or mansion blocks, so a bathroom is often directly above a neighbour’s ceiling. In Cranham, that’s a good reason to put tired sealant and grout right early.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Cranham questions
Can parking be tricky for a visit in Cranham?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
I live in a flat in Cranham. Can a failed seal leak into the flat below?
Yes. In a flat, water from a failed bath or shower seal has only one way to go, and that’s down. Cutting out the old sealant and laying a new bead early stops it getting that far.
Can old silicone be taken off without scratching the tiles?
Yes. We avoid heavy scraping and use the right cleaner for each surface.
My shower still leaks after a reseal. Can you sort it?
Yes. There’s normally a reason: sealant over sealant, movement or another leak, so we find that first.
Can you remove sealant that’s been put over old sealant?
Yes. We remove every layer; new silicone doesn’t bond to old silicone, which is why over-sealing fails.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint.
How long does the work take?
It takes a few hours for most joints, depending on how much old sealant has to come out. We’ll give you a timescale when we quote.
Is there any odour?
There can be a smell while the sealant cures. Ventilation helps.

Aftercare tips
Aftercare is simple, and it makes a real difference:
- Do not wait for a small gap to become a leak
- Find out why the sealant failed first
- Check trays and worktops do not move
- Keep the room well ventilated
Go easy on the new sealant: no scraping, scouring pads or harsh chemicals.
Mould trapped under over-sealed joints spreads unseen. By the time it shows through, the joint is well past saving.

Remedial sealant around Cranham
London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, so tired sealant is best dealt with early. London’s water is hard, so limescale builds up on sealant, grout and fittings.
Cranham is in London, so parking needs planning: let us know about parking bays, permits or a driveway. Schools such as Hall Mead School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes.

What we do, step by step
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take a few hours for most joints, depending on how much old sealant has to come out. For a job in Cranham, 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.
- We start by checking the joint for movement, leaks and the reason it failed.
- We strip the joint completely, removing any layers below.
- Next, any mould is treated and the joint dried.
- We use the right backing and sealant for any joint that moves.
- Finally we finish the joint and talk you through what we found.

DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Different surfaces, different methods
Over-sealed & botched joints
Previous removal attempts can leave scratches or gouges. We work carefully to avoid adding to it, and point out any existing damage.
Windows & doors
Smeared or badly matched mastic can be cut out and redone neatly, in a colour that suits the frame.
When to call us in Cranham
Some joints fail because water is reaching them from behind. A leaking valve, a failed waste or cracked grout feeds water behind the bead, and the sealant lifts or goes mouldy from underneath.
It’s worth asking for a quote if you see:
- Products that weren’t meant for the joint
- A shower that leaks however often it’s resealed
- Beads that never stuck properly
- Dark patches showing through the sealant
For landlords with property near Upminster station, botched sealant from a previous quick fix is easier to strip out between tenants.
