New Eltham questions
Could a tired shower seal in my New Eltham flat affect the neighbours 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.
Is parking a problem for a job in New Eltham?
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.
What should I tell you?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply phone 0345 464 0079 or email us.
Can landlords and businesses book you?
Yes. We work for householders, landlords, letting agents, businesses and hotels.
Can you reseal a split movement joint?
Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.
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 I add another job to the visit?
Yes. Just list everything you need and we will quote it together.
Remedial sealant for homes and businesses in New Eltham
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint fails however neatly it’s applied. Out it comes, and in goes a sealant suited to the job. We’re often asked to deal with torn expansion joints and over-sealed joints coming away, across leaking tray & enclosure joints, shrunken worktop sealant and mouldy bath & shower sealant.
In much of London, period terraces have been converted into flats over the years, with bathrooms fitted into whatever space was available. A compact bathroom that steams up every day is hard on silicone and grout, and homes in New Eltham are no different.
A one-year guarantee comes as standard.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Act on a lifting corner straight away
- Do not add new sealant on top of old
- Find out why the sealant failed first
- Do not point over movement joints
Where we’ve pointed out another fault, have it put right, or the new joint may fail again.
A split movement joint lets rain into walls and floors, and left long enough, the edges of the joint can crumble. A joint with sound edges is far easier to reseal.
Why it’s worth doing now in New Eltham
Stripping out botched sealant adds time to a reseal, but not by much: the work takes a few hours, depending on how many layers have to come out. It’s far less disruption than resealing the same joint again and again. In a flat in New Eltham, 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.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first.

Honest limits
New sealant cannot fix everything, and we’d rather say so up front. It will not solve:
- A tray or worktop that needs refixing first
- A cracked shower tray or bath (that needs repair or replacing)
- Water damage behind tiles that needs a tiler
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly before you book.
Joints and surfaces we work on
- Shrunken worktop sealant

What we do, step by step
The work is kept neat and contained to the area we are working on, so you can get on with your day. Expect the work to take a few hours for a typical bath or shower, longer where several layers have been applied. In a London area like New Eltham, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- We protect the surfaces around the joint.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- New sealant goes in once the joint is dry, and is tooled smooth.
- We give you the cure time and explain what caused the failure.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Mention any sign-in or site rules at work premises
- For indoor joints, keep the area dry beforehand if you can

Other services in New Eltham
Do you need remedial sealant in New Eltham?
Sealant needs a clean, dry surface with no grease on it. Soap film, dust, damp or old residue stop it gripping, so it starts lifting sooner than it should.
Any of these means the joints need attention:
- Sealant peeling off a dusty or damp surface
- A shower that leaks however often it’s resealed
- Thick, messy sealant smeared over tiles
- Dark patches showing through the sealant
If you live in an older home near All Saints Church, walls and floors in older homes can move, and sealant and grout show it first.
What your quote should include
- How hidden problems are handled
- Who turns up on the day
- Whether they seal over old material or remove it
- What product goes in the joint
