Remedial sealant in Shipbourne
A movement joint stops working when its sealant splits or sets hard. The old sealant comes out and backing goes in to control the depth, before resealing with a flexible product suited to the movement. If you are dealing with gaps opening along the back of the worktop and a shower that leaks however often it’s resealed, we can help, on shrunken worktop sealant, mouldy bath & shower sealant and expansion joints alike.
Homes around Shipbourne are mostly houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. Sealant and grout wear out here just as they do anywhere: old material cut out, joints cleaned and a fresh finish laid.
Our work is backed for twelve months.

What happens if it’s left?
Spraying mould remover on a sealed-over joint does not reach what’s underneath. The layers have to come out. In a small place like Shipbourne, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and give you a clear price before any work starts.
What you get with us

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Run the fan after every shower
- Deal with small splits early
- Get the cause of a repeat leak found before resealing
- Use a soft cloth, not a scourer, on silicone
Do not let anyone seal over it later. Over-sealing is how many remedial jobs start, so the old bead should always come out first.
Mould under a second layer of sealant keeps growing out of sight. When it finally shows, the whole bead needs to come out.
What the job involves on each surface
Worktops & kitchens
If a worktop moves when you lean on it, the sealant will keep splitting. That needs refixing before resealing, and we will tell you if we find it.
Windows & doors
A frame that keeps leaking may not be the mastic. We check the joint and tell you if it looks to be something else.
DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

The process

Everything for the job comes with us, so a second trip is avoided where possible.

Common questions in Shipbourne
Will you come out to Shipbourne?
Yes, Shipbourne is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Borough Green & Wrotham station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Where are you based?
Mr Mastic is based in Crawley. We cover Shipbourne and the rest of Kent, along with the rest of our area.
What if the leak is not the sealant?
You’ll hear it from us. If it’s a cracked tray, a failed valve or a leaking waste, resealing won’t fix it, and we will not reseal for the sake of it.
When is the sealant fully cured?
Cure times vary by product. We tell you how long to leave it before we go.
Can you strip sealant from an acrylic tray safely?
Yes. We cut and lift the old sealant with tools suited to the surface, then clean off the residue. Any existing damage is pointed out before work begins.
When it is not the sealant
We’d rather tell you now than do work that will not last, so these are the limits:
- A bath, tray or worktop that moves until it’s properly fixed
- Tiles that have come away from the wall
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before you book.

What remedial sealant looks like in Shipbourne
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
For site and facilities teams at buildings such as Shipbourne School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Letting a property close to Borough Green & Wrotham station? Then botched sealant from a previous quick fix is easier to strip out between tenants. In the older streets around Church of St Giles, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.
