Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Stick to a soft cloth and a mild cleaner
- Keep an eye on the corners, where splits start
- Keep bottles off the sealant line
- Avoid abrasive pads on the sealant
Keep water off the new bead until it has cured, which is normally around 24 hours. After that, a quick wipe after showering helps keep it clean.
Mould that starts as a few spots spreads through the bead. Once it’s deep in the silicone, cleaning generally won’t remove it, and nearby grout often goes the same way. Replacing the sealant early keeps the job small.
Different surfaces, different methods
Shower trays & enclosures
The vertical joint where a screen profile meets the wall is a common leak point. It’s resealed along with the tray joints, following the enclosure maker’s guidance on which side to seal.
Basins & vanity units
Basin joints are short and close to eye level: so we keep the line tidy and even, finished in a colour that suits the basin.
How the visit works
Before we leave, we go over the finished joints with you. The visit itself usually takes a morning or an afternoon for most single baths and showers, depending on the size of the job. Somewhere as small as Colthrop, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Protection goes down around the bath, shower or worktop.
- We cut away the old sealant and clean off what’s left.
- Mould is treated, then the joint is left to dry thoroughly.
- Baths are filled first, then anti-fungal sanitary silicone is applied in a colour to suit.
- We finish the joint, clear up and tell you how long to leave it before it gets wet.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Let us know about stairs, lifts or work at height
- Clear the area around the work

Related advice
DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Colthrop homes and their sealant
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Schools such as Francis Baily Primary School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Letting a property close to Thatcham station? Then fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay.

What colours of sealant can you use?
You are not limited to white: clear, white and colours chosen to suit the room. We will talk it through when we quote.

One bath or shower is around two hours’ work, including cutting out the old sealant. A full bathroom and kitchen can take most of a day.
Is it worth trying it myself?

Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
What affects the quote in Colthrop
We don’t publish a price list, because no two jobs are the same. The quote depends on:
- The size of the job
- How many rooms, windows or areas are involved
- Whether there’s mould to deal with
- How much old sealant there is and how hard it is to remove
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, call 0345 464 0079 or email us and we will give you an honest view and a quote.
What we need to know
To make quoting easier, let us know:
- What the problem is, such as mould, gaps, leaks or cracking
- Access, such as stairs, a lift or height
- How many joints, rooms or windows are involved
- Photos by email, if that is easy
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.

What else we do in Colthrop
Do you need bathroom resealing in Colthrop?
Silicone needs a clean, dry surface without any grease to stick to. Traces of soap, bath oil and old sealant stop it gripping, so a rushed job can start to lift early.
Most people get in touch after spotting something like this:
- Water escaping at the shower enclosure
- Water getting behind the kitchen upstand
- Mouldy sealant that has gone black
- Leaks into the floor or ceiling below
For an older house near a landmark such as St Mary's Church, older homes can move a little, which is hard on rigid grout and tired sealant.
