- Failed sealant on the screen profile
- Black spots spreading through the bead
- Smears of silicone across the tiles
The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes half a day or less for one room, longer when the kitchen is included and we leave things clean and tidy. In a small place like Cobham, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, each joint is checked for movement and signs of water.
- Every trace of the old bead is removed, including the thin smear on the tiles.
- The joint is cleaned, degreased and treated for mould.
- With the joint dry, and any bath loaded with water, a single bead of anti-fungal silicone is applied.
- The bead is tooled smooth and you are told the cure time, normally around 24 hours.
How to prepare
- Try not to wet indoor joints just before the visit
- Mention any sign-in or site rules at work premises
- Mention any tricky access

How we handle bathroom resealing in Cobham
The bead of silicone around a bath, tray or worktop is what keeps water out of the gaps. Once it cracks or goes mouldy, water starts to find its way through and into the wall or floor. Our team cut the old bead out completely and lay a new one in anti-fungal sanitary silicone. If you have a joint torn by a bath that flexes and a reseal done over the top of the old bead, we can put it right.
Homes around Cobham are mostly houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. The work is the same as anywhere: everything old comes out before the new sealant or grout goes in.
All of our work is guaranteed for twelve months, in Cobham and everywhere else we cover.

What we cannot put right
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- A leaking waste, trap or valve
- Cracks in the tray itself rather than the joint
- Cracked or missing grout between tiles (that is regrouting)
If in doubt, call 0345 464 0079 or send us an email and we will say what we think before you book.
Surfaces we seal
- Shower trays & enclosures
- Wet rooms
- Kitchen worktops & upstands
- Basins & vanity units
- Sinks & splashbacks
- Baths
Landlords, agents and businesses in Cobham
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Letting agents and landlords in Cobham can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
What we’re called out for in Cobham
Plenty of failed sealant has been laid over the top of older sealant. New silicone won’t bond to old silicone, so it lifts, lets water in and traps mould underneath.
These are the problems we’re asked about most:
- Splits where the tray meets the wall
- Sealant that has split, shrunk or peeled away
- Black mould in the silicone that won’t clean off
- Failed sealant on the screen profile
Homes close to Parish Church of St Mary Magdalene include some older properties, and bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.
What your quote should include
- Are they insured?
- The length of the guarantee
- How the colour is chosen
- When the joint can take water or movement
FAQs for Cobham
I let a flat near Sole Street station. Can you help?
Yes, we work for landlords and letting agents. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.
Do you cover smaller places like Cobham?
Yes. Cobham is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can mouldy silicone be sorted out?
Yes. We strip the bead, treat the joint and lay new anti-fungal silicone.
Can you reseal around my kitchen sink and worktop?
Yes, often alongside a bathroom. Next to the sink we use a food-safe product where it’s needed.
Where do you work from?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
How long does a bath or shower reseal take?
One bath or shower is around two hours’ work, old sealant removal included. A whole bathroom plus the kitchen may take most of the day.
How the job changes by surface
Baths
A bath shifts slightly every time it’s filled, so we fill it with water before sealing. That way the joint is laid with the bath at its heaviest and is not stretched when it’s used.
Wet rooms
In a wet room, the joints between floor and walls take standing water. They get anti-fungal sanitary silicone, and our work is on the visible joints only.
Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Other services in Cobham
What happens if it’s left?
Tired sealant is not a reason to replace a bath or shower. Replacing the joint is normally all it takes, as long as the fittings themselves are sound. If something else is wrong, we’ll tell you. Older cottages and farmhouses around Cobham can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.
