About bathroom resealing in TW3
Homes in TW3 have the same weak spots as anywhere else: bath edges, tray joints, basin backs and kitchen upstands. Every joint is cut out, cleaned and left dry before it’s resealed. We work on baths, shower trays & enclosures and kitchen worktops & upstands, and people most often call us about water getting behind the bath panel and gaps where the bath or tray has moved.
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes two to three hours for a typical bath, depending on how much old sealant there is.
- Protection goes down around the bath, shower or worktop.
- Old sealant is sliced away and the residue removed.
- Mould is treated, then the joint is left to dry thoroughly.
- Any bath is filled with water, then we lay a bead of anti-fungal silicone in white, clear or a matching colour.
- The joint is finished neatly and we explain when it can get wet.

Bathroom resealing across TW3: local notes
From Twickenham, Hounslow and Isleworth to its smaller places, homes across TW3 have bathrooms and kitchens of every age. Family bathrooms, rented flats and hotel en suites all need their sealant and grout renewing in time.
London and the South East are among the drier parts of the UK, but outdoor sealant still needs a dry day and clean surfaces, so outside work in TW3 is planned around the forecast.
Hounslow: In the older streets around Church of St Mary the Virgin, timber floors under older bathrooms flex, so joints need a sealant that moves with them. Rented homes near Hounslow station change hands often, and mouldy sealant is one of the first things a new tenant notices, so it’s worth renewing between lets.
Leave it or put it right?
Sorting it now is quick: the work takes half a day or less for one room, longer when the kitchen is included. Left until water gets through, the job can grow to lifting panels, drying out and decorating.
What your quote should include
- What insurance they hold
- What product goes in the joint
- How the surfaces are prepared before sealing
- Who turns up on the day
What we are called out for in TW3
Sealant laid on a damp, dusty or greasy joint never bonds properly. Soap residue, oils and leftover silicone film all get in the way, so a rushed job can start to lift early.
Common reasons people contact us are:
- A reseal done over the top of the old bead
- A bead that has pulled away from the tiles
- Failed sealant on the screen profile
- Black spots spreading through the bead
When it isn’t the sealant
It helps to know what we can’t do too:
- A tray that rocks until it’s re-bedded
- Tiles that have come away from the wall
- A leaking waste, trap or valve
How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Use gentle cleaners on the silicone
- Keep an eye on the corners, where splits start
- Keep scourers and sharp tools away from the bead
- Don’t leave water standing on kitchen joints
Have a look at the joints every few months. A small split or a corner lifting is easy to spot, and if anything looks wrong, just call 0345 464 0079 or drop us an email.
Watch for the early signs: a corner lifting, a gap behind the bead, a dark line under the silicone or a damp patch on the ceiling below. Any of these means the joint needs attention.
Surface by surface
Basins & vanity units
A vanity top has a joint along the wall and sometimes at the sides. If water gets in, the cabinet underneath can swell, so the joint is sealed in one unbroken line.
Wet rooms
Not every wet room leak is a sealant problem. We check the joints and say so if the fault looks to be elsewhere.
FAQs for TW3
Can you get rid of the black mould in my sealant?
Yes, by replacing the sealant. Sprays can fade the marks, but cutting it out and resealing is what lasts. Good ventilation helps keep it away.
Do you have insurance?
Yes, we are fully insured.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures.
Can new silicone go straight over the old?
No, and it’s one of the main reasons reseals fail. We cut out all of the old sealant, clean the joint and start again.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we’re using.
