Bathroom resealing in Sunbury-on-Thames
Before a bath is sealed, it’s filled with water. The weight settles the bath to its lowest point, so the new joint is not pulled apart the first time it’s used. It’s a small step that rushed reseals tend to skip. If you are dealing with black spots spreading through the bead and water getting behind the bath panel, we can help, on baths, basins & vanity units and shower trays & enclosures alike.
In a town like Sunbury-on-Thames, older streets sit alongside newer estates, so bathrooms range from long-standing suites to recent refits. Either way, the sealant and grout are generally the first things to fail.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes around two hours for one bath or shower, longer for a whole bathroom. For a job in Sunbury-on-Thames, we need access to where the work is and somewhere nearby to park. If the job is outside, mention gates, side access and anything above ground floor.
- 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.
- Baths are filled first, then anti-fungal sanitary silicone is applied in a colour to suit.
- The joint is finished neatly and we explain when it can get wet.
Getting ready for the visit
- Keep children and pets away from the work area
- Let us know about stairs, lifts or work at height
- Let us know about earlier repairs to the joints
How to get a quote
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. A few photos by email make the job easier to understand.

Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Dry worktop joints after washing up
- Keep the fan on for a while after bathing
- Check the joints every few months for splits or lifting
- Do not let bottles sit on the bead
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 ring 0345 464 0079 or send us an email.
Small signs come before a leak: 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.

Do you hold any approvals?

My sealant has gone black. Can you sort it?
Yes, we can. The old sealant comes out, the mould is treated, and we reseal with anti-fungal sanitary silicone.
What colours of sealant can you use?
You are not limited to white: white, clear and colours to suit tiles and worktops. We will talk it through when we quote.
Where are you based?
We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
For landlords and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll quote.
For anyone letting property in or around Sunbury-on-Thames, several properties can be quoted together. Just tell us the addresses and what each one needs.
Sunbury-on-Thames homes and their sealant
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Letting a property close to Sunbury station? Then fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay. Managing a site like St Ignatius RC Primary School? Then we reseal washrooms and kitchens in schools and businesses as well as homes.

What the job involves on each surface
Baths
The long joint down the side of a bath is where most leaks start, especially under a shower. We finish it with a single, even bead of anti-fungal silicone.
Shower trays & enclosures
If a tray moves underfoot, new silicone won’t last. We check for movement before we reseal, and tell you if it needs re-bedding first.

Signs you need bathroom resealing in Sunbury-on-Thames
With age, silicone loses its stretch. Along worktops it tends to pull back from the wall, leaving a thin gap where water and food collect. Heat from the hob and strong sprays speed it along.
It’s worth asking for a quote if you see:
- Black spots spreading through the bead
- Water escaping at the shower enclosure
- Damp behind the bath or under the tray
- Cracked, shrunken or lifting silicone
For an older house near a landmark such as St Saviour, older homes can move a little, which is hard on rigid grout and tired sealant.
What your quote should include
- Whether you can choose the colour
- How the joint is cleaned and prepared
- Who does the work, and how experienced they are
- What product goes in the joint
Leave it or put it right?
A quick bead over the top of the old one might look better for a while, but it can’t stick to what’s underneath. It lifts, traps water and grows mould behind it, so the next person has twice as much to remove. Around Sunbury-on-Thames, failed sealant lets water into hidden places, such as under the floor, behind a panel or into a wall. Left alone, that means rot, damp and a bigger repair.
The cost depends on how much there is to do, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.
