Leave it or put it right?
Ripping out a bathroom isn’t generally needed. If the bath, tray and tiles are sound, remedial resealing generally puts it right. Where something else has failed, you’ll hear it from us. In a smaller place like Ventnor, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.

Remedial sealant in Ventnor
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 have floor or wall movement joints that have failed and over-sealed joints coming away, we can put it right.
Homes around Ventnor range from older cottages to more recent houses. In older homes, walls and floors can move a little more, so the right flexible sealant matters.
A 12-month guarantee comes as standard.

Ventnor has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and can be done room by room.
If you look after a building such as St Catherine's 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.

What the job involves on each surface
Movement & expansion joints
A movement joint must be able to stretch. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed.
Leaking trays & enclosures
Where the joints are the problem, every bead is stripped and resealed with anti-fungal sanitary silicone, including the screen profile and tray edges.
For landlords and businesses
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
We also work for property managers and facilities teams. We can quote a run of properties together, and we’re fully insured.

What else we do in Ventnor
How to look after the new joints
To keep the joints looking good and working properly:
- Report a tray that rocks or a worktop that lifts
- Use a soft cloth, not a scourer, on silicone
- Ask why a joint failed before redoing it
- Keep an eye on the ceiling below the bathroom
If the joint ever needs renewing, have it cut out, not sealed over. New silicone doesn’t bond to old.
Mould under a second layer of sealant keeps growing out of sight. When it finally shows, the whole bead needs to come out.
Do you need remedial sealant in Ventnor?
Sealant needs a clean, dry surface with no grease on it. Residue, moisture or dust left in the joint weaken the bond, and the joint starts to come away early.
The problems people generally mention when they call are:
- Dark patches showing through the sealant
- Floor or wall movement joints that have failed
- Over-sealed joints coming away
- Sealant that came away because the surface wasn’t prepared
In the older streets around St Catherine's Church, walls and floors in older homes can move, and sealant and grout show it first.

The process
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. It normally takes a few hours, depending on how many layers have to come out. For a job in Ventnor, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Each layer is cut out and the residue cleaned off.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Mention any sign-in or site rules at work premises
- Tell us about any water getting in
