Bathroom resealing in Newington Green
A fresh bead of silicone changes how a bathroom looks more than most people expect. Black, patchy sealant makes clean tiles look tired, and a neat new joint puts that right in a short visit. Just as important, it closes the gaps water would otherwise get through. If you have a reseal done over the top of the old bead and gaps between the worktop and the wall, we can help, whatever the surface.
London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. In Newington Green, bathroom resealing is as much about a room looking cared for as about keeping water out.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Aftercare tips
After the cure time, these simple habits help:
- Keep bottles off the sealant line
- Let new sealant cure fully before it gets wet
- Keep scourers and sharp tools away from the bead
- Clean with a mild bathroom cleaner and a soft cloth
Check the sealant now and then. Small splits and lifting ends are easy to catch early, so if something doesn’t look right, just call 0345 464 0079 or drop us an email.
A few black dots in the silicone soon become a black line. When it has grown right through, it rarely cleans out, and nearby grout often goes the same way. Catching it early keeps it a simple reseal.
DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Signs you need bathroom resealing in Newington Green
Sealant laid on a damp, dusty or greasy joint never bonds properly. Soap residue, oils and leftover silicone film all get in the way, so a rushed job can start to lift early.
The problems people usually mention when they call include:
- Black mould in the silicone that won’t clean off
- Leaking joints on a shower screen
- Lumpy, uneven sealant from a DIY attempt
- A bead that has pulled away from the tiles
If you look after a building such as Newington Green Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes.
Questions to ask before booking
- Which colour the sealant will be
- Are they insured?
- Is the old sealant removed completely?
- Which sealant they’ll use, and why
What the job involves on each surface
Basins & vanity units
On a basin, neatness shows: the bead is right in front of you, so it’s tooled cleanly and evenly, in white, clear or a colour to suit.
Wet rooms
In a wet room, the joints between floor and walls take standing water. They’re resealed with anti-fungal sanitary silicone, and our work is on the visible joints only.

How the visit works
At the end, we look at the finished work together and tell you how long to leave it. The visit itself generally takes around two hours for one bath or shower, longer for a whole bathroom, depending on the size of the job. For a job in Newington Green, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- First the area is protected and every bit of old sealant removed.
- We clean and degrease the joint and treat any mould.

Common questions in Newington Green
Is parking an issue for bathroom resealing in Newington Green?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
I live in a flat in Newington Green. Can a failed seal leak into the flat 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.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
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.
How long does the new silicone need before I use the shower?
Generally after around 24 hours. We will tell you the cure time for the product we used.
Do you have insurance?
Yes. We’re fully insured, and we can confirm the details when we quote.
Can new silicone go straight over the old?
No. New silicone will not bond to old silicone, so it lifts and traps water and mould underneath. We always take the old sealant out completely.
How long does a bath or shower reseal take?
Allow around two hours for one bath or shower, longer for a whole bathroom. You will know how long to expect before we start.
