- Black mould underneath the bead
- Torn expansion joints
- Repeat leaks from the same joint
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Use a soft cloth, not a scourer, on silicone
- Keep movement joints clear of mortar and paint
- Keep an eye on the ceiling below the bathroom
- Check trays and worktops don’t move
Do not let anyone seal over it later. New silicone does not bond to old, so the old bead should always come out first.
A split movement joint lets rain into walls and floors, and left long enough, the edges of the joint can crumble. Resealing while the edges are sound is simpler.
Remedial sealant in Bowmans, 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. Common call-outs are for black mould underneath the bead and repeat leaks from the same joint, across leaking tray & enclosure joints, failed movement joints and shrunken worktop sealant.
Around Bowmans, you will mostly find houses and bungalows, from older cottages to newer builds. Bathrooms and kitchens here get the same daily wear as anywhere, and the sealant and grout show it first.
Big or small, it’s backed by our one-year guarantee in Bowmans and across Kent.

Different surfaces, different methods
Mouldy bath & shower sealant
Mould that has grown into silicone does not clean out for good. All of it comes out, and the joint is treated and dried ahead of a new anti-fungal bead.
Over-sealed & botched joints
A thick bead smeared across tiles often hides mould or gaps. Taking it back shows what’s underneath.
Do you need remedial sealant in Bowmans?
Water from somewhere else can ruin a good seal. A slow leak behind the tiles soaks the joint from the back, so the silicone goes mouldy or lets go.
Signs it’s time to call us include:
- Black mould underneath the bead
- Caulk or the wrong sealant used in a wet area
- Floor or wall movement joints that have failed
- Worktop sealant that has shrunk and split
Homes close to St Barnabas include some older properties, and walls and floors in older homes can move, and sealant and grout show it first.

Your questions about remedial sealant in Bowmans
Is Bowmans in your area for remedial sealant?
Yes, Bowmans is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear quote.
Can you help a landlord with a rental near Crayford station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we will send you a clear quote.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
Can you quote for more than one area?
Yes. More than one area can be quoted together.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
How long does remedial resealing take?
Longer than a simple reseal, because every layer has to come out. For most joints, it’s a few hours, and we confirm the time with your quote.
What if the leak isn’t the sealant?
Then we explain what we’ve found. You may need a plumber or bathroom fitter before any new sealant goes on.
Can I choose the sealant colour?
We help you choose a colour that suits, from white and clear to greys and other shades. The choice depends on the product the joint needs.
Bathrooms and kitchens in Bowmans
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
If you let a flat or house near Crayford station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. Schools such as Wentworth Primary School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes.

For a walk, there’s Wansunt Pit.
Should I try it myself first?
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.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
What happens on the day
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes a few hours for a typical bath or shower, longer where several layers have been applied from start to finish. For a job in Bowmans, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We protect the surfaces around the joint.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.
- Once dry, a suitable sealant is applied and tooled.
- You get the cure time and our view on why the joint failed.
Preparing for the visit
- On commercial sites, let us know about site rules
- For indoor joints, keep the area dry beforehand if you can
- Clear items away from the joints we are working on

Advice
What sealant work cannot fix
Before booking, it’s worth knowing the limits too:
- A tray or worktop that needs refixing first
- Sealant in an older building that needs testing for asbestos first
- Plumbing leaks behind walls or under trays
If in doubt, call 0345 464 0079 or send us an email and we will say what we think.
Surfaces we seal
- Expansion joints
- Mouldy bath & shower sealant
- Botched or over-sealed joints
- Shrunken worktop sealant
- Leaking tray & enclosure joints
- Failed movement joints
What happens if it’s left?
Stripping out botched sealant adds time to a reseal, but rarely a lot: the work takes a few hours for most joints, depending on how much old sealant has to come out. Compared with chasing the same leak every few months, it’s time well spent. Homes in smaller places like Bowmans can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
