About our bathroom resealing in Blackfen
It isn’t only bathrooms. The joint between worktop and wall, the edge of the sink and the bottom of the splashback all take splashes every day, and water that gets into the back edge of a worktop can swell the board. We reseal them with a kitchen-suitable silicone, matched to the worktop where it’s on show. If you’re dealing with a bead that has pulled away from the tiles and failed sealant on the screen profile, we can help.
London homes include a lot of flats, conversions and mansion blocks, and many bathrooms sit right above someone else’s ceiling. In Blackfen, that is a good reason to put tired sealant and grout right early.
You’re covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What we do, step by step
We keep the work tidy and contained to the joints we’re treating. The job normally takes a morning or an afternoon for most single baths and showers, and we explain the cure time before we leave. In Blackfen, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- 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.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Tell us about any previous sealing or DIY attempts
- Let us know about parking restrictions

Advice
Why deal with it now?
A quick bead over the top of the old one might look better for a while, but it will not bond. Water creeps under it and mould follows. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Blackfen, the repair is bigger than a sealant job.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
Why us?
- Experience in homes, commercial sites and hotels
- White, clear, grey or another colour, product permitting
- Over 20 years’ experience
- You choose the colour before work begins

What else we do in Blackfen
For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
In hotels, rooms out of use cost money, so we plan the work room by room. We have worked in hotels as well as homes and businesses.
What we are called out for in Blackfen
Not every tube in the shop is meant for a shower. Decorators’ caulk and all-purpose sealants aren’t made for constant wetting, so they stain, crack or go mouldy before long. A bathroom joint needs anti-fungal sanitary silicone.
Most people get in touch after spotting something like this:
- Two layers of silicone, both failing
- Gaps where the bath or tray has moved
- Gaps between the worktop and the wall
- A bead that has pulled away from the tiles
If you live in an older home near Church of the Good Shepherd, walls and floors in older homes can move, and sealant and grout show it first.
What your quote should include
- Whether they seal over old material or remove it
- Whether they’re fully insured
- Which colour the sealant will be
- How the joint is cleaned and prepared
Questions from Blackfen
I let a flat near Falconwood station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can go on one quote. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.
Could a tired shower seal in my Blackfen flat affect the neighbours below?
It can, yes: water that gets past a split bead or cracked grout often runs under the tray and shows on the ceiling below. Replacing the sealant and grout before that happens is much less trouble than repairing a neighbour’s ceiling.
How long does a bath or shower reseal take?
It depends on how many joints there are and how much old sealant has to come out. Allow a couple of hours for a typical bath or shower.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Can you get rid of the black mould in my sealant?
Yes, we replace the mouldy bead. Cleaning products may lighten it, but the lasting fix is new anti-fungal silicone on a clean, treated joint. Good ventilation helps keep it away.
Do you come to Blackfen?
Yes. We are based in Crawley and work across South East England, London and Scotland, Blackfen included.
Can you just seal over the old silicone?
No, never. A bead laid over old silicone soon starts to come away. We remove the old bead completely before resealing.
Where are you based?
Our base is Crawley. We work across South East England, London and Scotland.
Bathroom resealing in Blackfen: local notes
London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, so tired sealant is best dealt with early. London has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
As a London address, Blackfen can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. Managing a site like Our Lady of the Rosary Catholic Primary School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

How to look after the new joints
After the cure time, these simple habits help:
- Use gentle cleaners on the silicone
- Wipe the sealant dry after showering
- Look for lifting corners and small gaps now and then
- Keep the fan on for a while after bathing
Give the silicone time to cure before it gets wet, following the cure time we give you. Once it’s cured, wiping it down after use keeps it looking new.
A failed kitchen joint is easy to miss. Water gets behind the upstand and into the edge of a laminate worktop, where it can make the board swell. Resealing before that happens protects the worktop.
Surface by surface
Shower trays & enclosures
Shower trays are sealed to the wall, and enclosures are sealed to the tray and tiles. Both get soaked every time the shower runs, so both are resealed with anti-fungal sanitary silicone.
Basins & vanity units
Vanity units have long, worktop-style joints against the wall. If water gets in, the cabinet underneath can swell, so a neat, continuous bead matters.
