Remedial sealant in Gustard Wood, done properly
If a joint fails again and again, something is causing it. A tray that moves, a worktop that isn’t fixed, the wrong sealant or water getting in elsewhere will beat any new bead. We look for the cause before we reseal. We are often asked to deal with dark patches showing through the sealant and sealant that came away because the surface wasn’t prepared, across shrunken worktop sealant, failed movement joints and leaking tray & enclosure joints.
For a small place like Gustard Wood, remedial sealant is planned like any other job: the journey and access are simply agreed in advance. Once we are there, the bathroom or kitchen gets the same care as anywhere else.
All of our work is guaranteed for twelve months.

When it isn’t the sealant
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Water damage behind tiles that needs a tiler
- A tray or bath that is cracked
- A leaking trap, valve or supply pipe
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly before you book.
Surfaces we seal
- Shrunken worktop sealant
- Expansion joints
- Failed movement joints
- Mouldy bath & shower sealant
- Leaking tray & enclosure joints
- Botched or over-sealed joints
How to look after the new joints
After the cure time, these simple habits help:
- Check trays and worktops don’t move
- Run the fan after every shower
- Act on a lifting corner right away
- Do not point over movement joints
Clean gently: no scraping, scouring pads or harsh chemicals.
Leaks through failed sealant grow over time. Each use pushes more water behind the bead, into floors, walls or ceilings. Early action keeps it to a sealant job.
Why act early in Gustard Wood
Mould under a bead cannot be reached by cleaning. Removal is the only way to get at it. Around Gustard Wood, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Signs you need remedial sealant in Gustard Wood
Water from somewhere else can ruin a good seal. A slow leak behind the tiles soaks the joint from the back, and the sealant lifts or goes mouldy from underneath.
Common reasons people contact us include:
- Movement joints that have split or pulled away
- Over-sealed joints coming away
- Mould trapped under a layer of silicone
- A shower that leaks however often it’s resealed
For an older house near a landmark such as St Peter, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

We bring what the job needs, so it can be finished in one trip where possible.

Related advice
DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What the job involves on each surface
Leaking trays & enclosures
When failed joints are the cause, they’re all cut out and renewed, tray edges and screen profiles included.
Over-sealed & botched joints
Every layer has to come out, and silicone residue is cleaned off the tiles too. Only a clean joint will take a new bead.
