Rotherhithe Bathroom Resealing
We cover Rotherhithe for bath, shower, basin, wet room, worktop and sink resealing. Old sealant removed completely, joints prepared properly.

How we handle bathroom resealing in Rotherhithe
Resealing is a small job that makes a big difference. Black, patchy sealant makes clean tiles look tired, and a clean white or clear joint fixes it quickly. Just as important, it closes the gaps water would otherwise get through. If you are dealing with gaps where the bath or tray has moved and smears of silicone across the tiles, 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 Rotherhithe, that is a good reason to put tired sealant and grout right early.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Rotherhithe questions
Could a tired shower seal in my Rotherhithe flat affect the neighbours below?
Yes, it can. Water that gets past failed sealant or cracked grout can run under the bath or tray and show up on the ceiling below. It’s far simpler to replace tired sealant early than to deal with a neighbour’s ceiling.
Do you work for hotels and guest houses in Rotherhithe?
Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Do you work in Rotherhithe?
We do. Our applicators work in Rotherhithe.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
My sealant has gone black. Can you sort it?
Yes. Once mould has grown into the silicone, it normally can’t be cleaned out for good, so we cut it out, treat the joint and reseal with anti-fungal silicone.
How long does the new silicone need before I use the shower?
The surface skins over fairly quickly, but the bead needs longer to cure right through. Leave it around 24 hours before it gets wet, or as long as we advise for that product.
Do you guarantee your resealing?
Yes. Our one-year guarantee covers every job, and we’re ARBOMaster approved applicators.
Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.

Bathroom resealing around Rotherhithe
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.
If you live in an older home near Holy Trinity Church, walls and floors in older homes can move, and sealant and grout show it first. Managing a site like Alfred Salter Primary School? Then we reseal washrooms and kitchens in schools and businesses as well as homes.

Signs you need bathroom resealing in Rotherhithe
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 crack, discolour or grow mould quickly. A bathroom joint needs anti-fungal sanitary silicone.
Keep an eye out for any of the following:
- Sealant that has split, shrunk or peeled away
- Mouldy sealant that has gone black
- Damp behind the bath or under the tray
- Shrunken sealant along the back of a worktop
Rotherhithe is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
Before booking anyone
- What insurance they hold
- Whether you can choose the colour
- How hidden problems are handled
- How the joint is cleaned and prepared
What happens if it’s left?
Mould removers can fade the surface of a stained bead, but where mould is inside the silicone it usually comes back. Cutting it out and resealing with anti-fungal silicone is the fix that lasts. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Rotherhithe, the repair is bigger than the sealant job would have been.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

When it is not the sealant
In fairness, some problems need a different trade:

- A tray or bath that’s cracked through
- Tiles that have come away from the wall

What we do, step by step
The work is kept neat and contained to the joints we’re treating, so you can get on with your day. The job usually takes a morning or an afternoon for most single baths and showers, and we tell you how long to leave it before we go. For a job in Rotherhithe, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- First, each joint is checked for movement and signs of water.
- The old silicone is cut out completely, along with the film it leaves on the tiles.
- Joints are degreased and any mould is treated.
- When the joint is dry, and a bath has been filled with water, the new silicone goes on.
- We tool the bead to a neat finish and give you the cure time, generally around 24 hours.
Preparing for the visit
- Move anything stored near the joints
- Tell us about any water getting in
- Tell us about access, such as stairs, a lift or high-level joints

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Keep scourers and sharp tools away from the bead
- Give the silicone its full cure time
- Look for lifting corners and small gaps now and then
- Dry worktop joints after washing up
Keep bottles and razors off the sealant line, because they trap water against the silicone. A quick squeegee after showering helps the joint dry.
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. If you spot one, it’s time to reseal.
