The process
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a typical bath or shower, longer where several layers have been applied. For a village or hamlet like Sepham Heath, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking the joint for movement, leaks and the reason it failed.
- Every layer of old sealant is cut and cleaned out.
- We clean the joint, treat any mould and let it dry.
- Moving joints get backing and a flexible sealant to suit.
- We tool the joint and tell you about anything else that needs attention.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Let us know about earlier repairs to the joints
- Mention any parking rules near the property

Remedial sealant in Sepham Heath
In Sepham Heath, as anywhere, remedial jobs tend to look alike: over-sealed joints, hidden mould, repeat leaks and split movement joints. Each is stripped back and done again properly. If you have a shower that leaks however often it’s resealed and thick, messy sealant smeared over tiles, we can help, on botched or over-sealed joints, mouldy bath & shower sealant and failed movement joints alike.
Somewhere as small as Sepham Heath, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

Sepham Heath homes and their sealant
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.
If you live in an older home near Otford Lane Mission Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them. For landlords with property near Knockholt station, a joint that keeps failing is best fixed properly while the property is empty.

What we are called out for in Sepham Heath
Joints that move need sealant that can stretch. Flexing baths, rocking trays and building movement joints split any bead that’s too stiff or too thin.
Signs it’s time to call us include:
- Sealant applied over old sealant that has lifted
- Beads that never stuck properly
- Black mould underneath the bead
- Thick, messy sealant smeared over tiles
For site and facilities teams at buildings such as Halstead Community Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes.

Different surfaces, different methods
Worktops & kitchens
If a worktop moves when you lean on it, the sealant will keep splitting. It needs fixing down first, which we’ll point out.
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.
When something else is needed
Before you book, it’s worth knowing the limits too:
- Failed tanking or loose tiles behind the sealant
- A bath, tray or worktop that moves until it’s properly fixed
- Plumbing leaks behind walls or under trays
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly.
What we seal
- Failed movement joints
- Botched or over-sealed joints
- Shrunken worktop sealant
- Leaking tray & enclosure joints
- Expansion joints
- Mouldy bath & shower sealant
Looking after it afterwards
To keep the joints looking good and working properly:
- Clean sealant with mild products only
- Act on a lifting corner right away
- Air the bathroom so the sealant can dry
- Get the cause of a repeat leak found before resealing
Keep the room ventilated: run the fan during and after showers, or open a window.
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.
