Remedial sealant in Stonehill Green: local notes
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you let a flat or house near Swanley station, botched sealant from a previous quick fix is easier to strip out between tenants. For site and facilities teams at buildings such as Hextable School, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes. In the older streets around St Peter, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

Stonehill Green: your questions answered
Do you work for landlords with property near Swanley station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can go on one quote. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Will you come out to Stonehill Green?
Yes, Stonehill Green is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected.
Someone resealed my shower and it’s leaking again. Can you help?
Yes. We will take all the sealant out, look for why it failed and reseal it properly.
Can you remove old sealant without damaging the bath?
Yes. The old bead is cut and lifted with tools that suit the surface, and the residue is cleaned away. Any existing damage is pointed out before we start.
Do you offer different sealant colours?
In most cases you can choose. We will tell you which colours the right product comes in.
Do you take out the old sealant first?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
DIY versus a professional finish
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.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
What happens on the day
You don’t need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the job takes a few hours for most joints, depending on how much old sealant has to come out for a typical job. Somewhere as small as Stonehill Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at how the sealant has failed and check for movement or a leak path.
- Every layer of old sealant is cut and cleaned out.
- The joint is cleaned, treated for mould and left to dry.
- Moving joints get backing and a flexible sealant to suit.
- The new joint is tooled neatly and we explain anything else we found.
Before we arrive
- Let us know about parking restrictions
- Keep pets and children clear of the area while we work
- Tell us about any previous sealing or DIY attempts

Different surfaces, different methods
Mouldy bath & shower sealant
Black mould inside the bead won’t scrub out. All of it comes out, and the joint is treated and dried before anti-fungal sanitary silicone goes in.
Over-sealed & botched joints
Previous removal attempts can leave scratches or gouges. We take care not to make it worse, and tell you about any damage we find.

Aftercare tips
How long the joints last depends on use and care. We suggest:
- Find out why the sealant failed first
- Keep bleach and abrasives off the bead
- Look for stains below bathrooms now and then
- Have loose fittings fixed before resealing
Where we have pointed out another fault, have it put right, because the new sealant cannot hold back a problem underneath.
Leaks through failed sealant grow over time. Every shower or downpour sends more water through, into whatever is behind or below. Early action keeps it to a sealant job.
What we cannot put right
Before you book, it’s worth knowing the limits too:
- Plumbing leaks behind walls or under trays
- Failed tanking or loose tiles behind the sealant
- A tray or bath that is cracked
If you are not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer before you book.
Joints and surfaces we work on
- Leaking tray & enclosure joints
- Expansion joints
- Mouldy bath & shower sealant
- Failed movement joints
- Shrunken worktop sealant
- Botched or over-sealed joints
Why act early in Stonehill Green
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. Where a wall is exposed, as many are in small places like Stonehill Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
