What we do, step by step
On the day, we start by going over the job with you, so you know exactly what we are doing. We protect the surfaces around the joints before work begins. Most jobs take a couple of hours for a single bath or shower. For a village or hamlet like Tewin Wood, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- Protection goes down around the bath, shower or worktop.
- We cut away the old sealant and clean off what’s left.
- We treat any mould and let the joint dry properly.
- Any bath is filled with water, then we lay a bead of anti-fungal silicone in white, clear or a matching colour.
- We finish the joint, clear up and tell you how long to leave it before it gets wet.
Getting ready for the visit
- Tell us if parking is tricky
- Where the joints are inside, avoid wetting them before we arrive

Bathroom resealing in Tewin Wood
Sealant is the soft line between a bath, shower or worktop and the wall. When it splits, shrinks or turns black, water gets behind it. Our team cut the old bead out completely and lay a new one in anti-fungal sanitary silicone. We work on wet rooms, kitchen worktops & upstands and baths, and common reasons people get in touch are black mould in the silicone that won’t clean off and shrunken sealant along the back of a worktop.
Around Tewin Wood, it’s houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. Sealant and grout wear out here just as they do anywhere: everything old comes out before the new sealant or grout goes in.
Each job carries a 12-month guarantee, whatever its size.

What happens if it’s left?
The difference in a professional reseal is mostly what you do not see: removing all the old sealant, degreasing the joint, treating mould and drying it properly. Without that preparation, the new bead won’t last. Around Tewin Wood, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Honest limits
To be straight with you, some problems need a different trade:
- Failed grout lines across the wall
- Loose or hollow tiles, or failed tanking behind them
- Cracks in the tray itself rather than the joint

DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

Is it messy?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
How long does it take to reseal a bath or shower?
A single bath or shower takes about a couple of hours, old sealant removal included. A full bathroom and kitchen can take most of a day.
Can you just seal over the old silicone?
No, never. Sealing over the top looks fine for a few weeks, then lifts, because silicone doesn’t bond to silicone. We remove the old bead completely before resealing.
Looking after it afterwards
So the new joints stay in good condition:
- Run the extractor fan during and after every shower
- Keep scourers and sharp tools away from the bead
- Move toiletries away from the joint
- Stick to a soft cloth and a mild cleaner
Treat the new bead gently when you clean: warm soapy water and a soft cloth do the job. Avoid scouring pads and anything sharp, and a nicked bead lets mould in sooner.
Worktop joints fail quietly. Water gets behind the upstand and into the edge of a laminate worktop, where it can make the board swell. A reseal in time can save the worktop.
What we are called out for in Tewin Wood
Silicone does not last for ever. Every shower, every splash and every wipe with a cleaner slowly wear it down, so its life depends on how the room is used, cleaned and aired.
These are the problems we are asked about most:
- A joint torn by a bath that flexes
- Water getting behind the kitchen upstand
- Water escaping at the shower enclosure
- Smears of silicone across the tiles
Letting a property close to Welwyn North station? Then mouldy sealant is one of the first things a new tenant notices, so it’s worth renewing between lets.
What your quote should include

- Whether they seal over old material or remove it
- How hidden problems are handled
- When the joint can take water or movement
