Bathroom resealing for homes and businesses in Coombe
A reseal only lasts if the joint is properly prepared. Every bit of old silicone comes out, down to the thin film left on the tiles, then the joint is cleaned, degreased and treated for mould. New silicone goes on only when the joint is fully dry. We’re often asked to deal with failed sealant on the screen profile and gaps where the bath or tray has moved, on baths, basins & vanity units and wet rooms.
Hard London water leaves limescale on sealant, grout and taps alike. In Coombe, bathroom resealing is as much about a room looking cared for as about keeping water out.
You are covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

Signs you need bathroom resealing in Coombe
Baths and trays move. Acrylic in particular gives slightly under the weight of water and a person, while a poorly supported tray can shift underfoot. That movement works at the bead until it splits or peels away.
It’s worth asking for a quote if you see:
- A messy, uneven bead from a previous reseal
- A bead that has pulled away from the tiles
- Failed sealant on the screen profile
- Mouldy sealant that has gone black
Coombe is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Bathroom resealing in Coombe: local notes
In a London flat, water from a failed bath or shower seal can reach the neighbours below, which is why it’s worth fixing early. London has hard water, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in.
For an older house near a landmark such as Church Hall United Reformed Church Of St Paul, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. Rented homes near South Croydon station change hands often, and fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay.

Looking after it afterwards
So the new joints stay in good condition:
- Keep an eye on the corners, where splits start
- Wipe up water along the back of the worktop
- Keep the fan on for a while after bathing
- Dry the bead with a towel now and then
Check the sealant now and then. A small split or a corner lifting is easy to spot, so if something does not look right, just ring 0345 464 0079 or send us an email.
Each shower pushes a little more water through a failed joint. Over time that water reaches floors, walls and ceilings. Early resealing closes the gap before damage is done.

What the job involves on each surface
Basins & vanity units
The back of a basin gets wet every time someone washes. Old sealant there often goes black at the corners, so it’s cut out and renewed just like a bath joint.
Baths
Baths move more than any other fitting, so it’s filled with water before the bead goes on. That way the joint is laid with the bath at its heaviest and isn’t stretched when it’s used.
What affects the quote in Coombe
For a quick quote, just ask. What matters most is:
- How much old sealant there is and how hard it is to remove
- Working hours on commercial sites
- Any mould that needs treating
- Whether the work is at height
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.
What we need to know
Photos help, but a description is a good start. Try to tell us:
- A few photos by email, if you can
- Any previous sealing or DIY work
- Where the property is
- The type of property
There’s no standard price list. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or send us an email.
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Your questions about bathroom resealing in Coombe
Can parking be tricky for a visit in Coombe?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Can you help a landlord with a rental near South Croydon station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
How long will the resealing take?
It takes a couple of hours for a single bath or shower. You’ll know how long to expect before we start.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
Do the sealants smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Do you do commercial work?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Do you do kitchens as well as bathrooms?
Yes. Kitchen joints get extra degreasing before the new bead goes on, then a colour-matched bead is laid.
Can mouldy silicone be sorted out?
Yes, we can. We strip the bead, treat the joint and lay new anti-fungal silicone.
What happens on the day
We bring everything the job needs with us. Once we’ve agreed what’s being done, we protect the area and start. It normally takes around two hours for one bath or shower, longer for a whole bathroom. In Coombe, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- We look at every joint first and check for movement or leaks.
- The old silicone is cut out completely, along with the film it leaves 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, generally around 24 hours.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Let us know about earlier repairs to the joints
- Tell us if parking is tricky

Why act early in Coombe
Mould removers can fade the surface of a stained bead, but mould that has grown into the sealant tends to return. Cutting it out and resealing with anti-fungal silicone is the fix that lasts. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in Coombe.
Doing several joints on one visit usually makes better use of the time than several visits. We’ll send you a clear quote for the lot.
