Remedial sealant in Heyshott, done properly
Remedial work is what we do when sealant has failed or been done badly. New sealant over old, smeared beads, unsuitable products and hidden mould all have to come out before the joint can be done properly. If you have sealant peeling off a dusty or damp surface and caulk or the wrong sealant used in a wet area, we can help.
Somewhere as small as Heyshott, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Movement in older walls and floors tends to show first as cracked grout or split sealant.
Our work is backed for twelve months.

Why deal with it now?
DIY removal often leaves scratches and a film of residue, and the residue left behind stops the next bead bonding. Careful stripping is where most of our time goes. Older cottages and farmhouses around Heyshott can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Call for a quick quote and we will go through it with you.

How the visit works
Before we leave, we go over the finished joints with you. The visit itself normally takes a few hours for a typical bath or shower, longer where several layers have been applied, depending on how much there is to do. For a village or hamlet like Heyshott, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we work out whether the problem is the sealant, movement or a leak.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- The right product goes in, with backing where the joint moves.
- We finish neatly and point out anything that needs another trade.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Tell us about any previous sealing or DIY attempts
- Mention any sign-in or site rules at work premises

What else we do in Heyshott
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
What sealant work cannot fix
In fairness, some problems need a different trade:
- Cracks in the fitting rather than the joint
- A leaking trap, valve or supply pipe
- Sealant in an older building that needs testing for asbestos first
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly before you book.

- Failed movement joints

What remedial sealant looks like in Heyshott
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.
Around Heyshott, as everywhere, remedial sealant is only as good as the preparation behind it. If you live in an older home near The Parish Church of St James, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Get the cause of a repeat leak found before resealing
- Run the fan after every shower
- Never fill a movement joint with mortar or grout
- Keep an eye on the ceiling below the bathroom
Don’t let anyone seal over it later. New silicone does not bond to old.
A failing joint rarely gets better on its own. Every shower or downpour sends more water through, into floors, walls or ceilings. Sorting it early limits the damage.
Surface by surface
Mouldy bath & shower sealant
Mould that has grown into silicone does not clean out for good. The sealant is cut out completely, the joint treated with a mould remover and dried ahead of a new anti-fungal bead.
Worktops & kitchens
If a worktop moves when you lean on it, the sealant will keep splitting. It needs fixing down first, and we will tell you if we find it.
