About our bath resealing in Chelsea Harbour
Resealing is one of the simplest ways to protect your bathroom. Failed sealant lets water get where it shouldn’t, and resealing puts a stop to that. Typical jobs include old sealant that looks dirty and black mould in the sealant, in wet rooms, kitchen worktops & sinks and basins & vanity units.
All of our repairs are guaranteed for twelve months. If something goes wrong with the work, we come back.

Questions from Chelsea Harbour
Can you price it without visiting?
Yes, almost always. A close-up and a wider photo are enough to give a fixed price.
Why does my sealant keep splitting?
The bath or tray is probably flexing. If it keeps happening, the support may need fixing.
Do I need to be at home?
Someone needs to let us in and show us the job. You don’t need to watch us work.
Will you leave a mess?
No. The work area is masked and covered, and we take our waste away with us.
Are you a vetted contractor?
Yes, including CHAS, Constructionline and SafeContractor. See our accreditations page for the full list.
Why does mould come back so fast?
Damp is the cause. Ventilation and drying keep it clean longer.
Will the price change on the day?
If we find something the photos didn’t show, we explain it first. The price only changes if you agree.
Is there any odour?
Some materials have a smell while they’re applied. It fades as everything cures.
Can I fix it myself?
For a hairline mark somewhere you will never see, a kit may be enough. For damage in plain view, cracks, holes or rust, or coloured finishes, a professional repair is worth it.
It’s tempting to reach for a kit, but the repairs we redo most frequently are DIY ones that have discoloured or lifted. Doing it properly first is generally the cheaper route.
For landlords and businesses
If you manage property in Chelsea Harbour, we’ll quote for several properties at once. Send pictures for each one and we’ll price them together.
Rental properties take more wear, and replacing things at every changeover adds up. Repairing between tenants keeps the property presentable for less.
Aftercare tips
Good habits make a big difference to how long a repair lasts:
- Reseal when black spots won’t clean off
- Store bottles on a shelf
- Keep the joints dry
- Ventilate the bathroom well
Good ventilation is the best protection, and wipe the joints after use so mould struggles to take hold.
Damp below or loose tiles need checking quickly. There may be more going on, so we’ll tell you if it needs a builder or plumber.
Do you need bath resealing in Chelsea Harbour?
No sealant lasts for ever. Every bath or shower adds moisture and soap residue, which mould loves, and the joint moves slightly every time the bath is filled.
Typical reasons for a call-out include:
- Missing sealant behind the taps
- Old sealant that looks dirty
- Gaps in the seal
- Leaks at the edges
Comparing quotes
- When it can be used again
- Whether the price covers travel
- Is the price fixed, and does it include VAT?
- What protection goes down before work starts
The process
We turn up when we said we would, introduces themselves and checks the damage against your pictures first. Dust sheets and masking tape go down before we open a single tin. Most visits take a couple of hours, and the room is left clean and tidy.
- The surrounding area is protected and the joints masked.
- Old sealant and residue are removed.
- We clean, treat and dry the joint.
- Fresh silicone is applied in a continuous bead.
- The bead is smoothed, the tape removed and the seal left to cure.
How to prepare
- Make sure the room can be ventilated
- Let us know if it has been repaired before
- Keep children and pets away from the room on the day

Advice
What a repair can’t fix
A repair isn’t right for every job, for example:
- Gaps so wide they need filling or trims before sealing
- Tiles that move, until they’re refixed
- Movement in the bath or tray

Why reseal now?
Resealing is routine maintenance. Leaving split or mouldy sealant can let water reach the walls and floor, which costs far more to put right. A repair is priced on what needs doing, not where you live. You’ll see the full price before you book, with no extras added later.
