Bathroom resealing across SE6: what to expect
Homes in SE6 have the same weak spots as anywhere else: bath edges, tray joints, basin backs and kitchen upstands. Every joint is cut out, cleaned and left dry before it’s resealed. We work on basins & vanity units, shower trays & enclosures and kitchen worktops & upstands, and common reasons people get in touch are gaps between the worktop and the wall and smears of silicone across the tiles.
There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes half a day or less for one room, longer when the kitchen is included.
- We protect the area and cut out all of the old sealant, including the film left on the tiles.
- Next, the joint is cleaned and any mould is treated.
- The joint is left to dry, and baths are filled with water first.
- New anti-fungal silicone goes on in a colour to suit and is tooled to a clean finish.
- We clear away and tell you when it can get wet, normally after around 24 hours.

Bathroom resealing across SE6: local notes
Our bathroom resealing work across SE6 covers homes, rentals and businesses, in Catford, Lewisham and Hither Green and well beyond. Wherever the job is, all the old material comes out before anything new goes in.
The South East is one of the drier parts of the UK, though outside sealant still needs a dry, clean joint, so work across SE6 is planned around the weather.
Catford: Homes close to Church of St Laurence and Community Centre include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them. For landlords with property near Catford Bridge station, fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay.
When it isn’t the sealant
We’d rather tell you now than do work that won’t last, so these are the limits:
- A leaking waste, trap or valve
- Movement from a bath with loose feet or no proper support
- Loose or hollow tiles, or failed tanking behind them
Keeping the joints in good condition
After the cure time, these simple habits help:
- Move toiletries away from the joint
- Clean with a mild bathroom cleaner and a soft cloth
- Never pick at the silicone with a blade
- Check the joints every few months for splits or lifting
Clean the silicone with care: a mild bathroom cleaner and a soft cloth is enough. Avoid scouring pads and anything sharp, and a nicked bead lets mould in sooner.
A split bead lets water through every time the bath or shower is used. Over time that water reaches floors, walls and ceilings. Early resealing closes the gap before damage is done.
What happens if it’s left?
You do not need a new bathroom because the sealant looks bad. A new bead often brings the whole room back. If we find a deeper problem, you’ll hear it from us.
Questions to ask before booking
- Whether you can choose the colour
- When the joint can take water or movement
- The length of the guarantee
- Is VAT in the price?
Different surfaces, different methods
Sinks & splashbacks
Water getting under the rim of an inset sink can soak the worktop. Where the sealant around the visible edge has failed, we renew it.
Wet rooms
Wet room floors move slightly as they’re used, so the internal corners need silicone rather than grout. Cracked grout in a corner can be cut out and replaced with silicone.
DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
FAQs for SE6
How long does it take to reseal a bath or shower?
That depends on the number of joints and the state of the old sealant. For most single baths or showers, allow a couple of hours.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us.
Do you come to SE6?
Yes, we do. Our applicators work in SE6.
Can tenants book the work?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Are you fully insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Can you get rid of the black mould in my sealant?
Yes, by replacing the sealant. Sprays can fade the marks, but cutting it out and resealing is what lasts. Airing the room well helps stop it returning.
