What bathroom resealing looks like in South Bank
In a London flat, water from a failed bath or shower seal can reach the neighbours below, so tired sealant is best dealt with early. South Bank has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.
If you look after a building such as Oasis Academy Johanna, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. For an older house near a landmark such as St John's Church, walls and floors in older homes can move, and sealant and grout show it first.
South Bank is about 1 mile west of London, in Greater London. From the centre of South Bank to the outskirts, we cover bathroom resealing for every kind of property. Across Greater London, we cover 764 places, South Bank among them.
We cover every part of SE1, WC2E and WC2N for bathroom resealing. Streets in the area include York Road, Spur Road and Lower Road, all of which we cover. South Bank sits on or near the A301 and A302, so getting to you is simple. Nearby, we also carry out bathroom resealing in Waterloo (1 mile south-east), Adelphi (1 mile north-west), Charing Cross (1 mile north-west), Temple (1 mile north-east) and Aldwych (1 mile north). Within a short drive, we also cover Kensington (4 miles west), Walthamstow (7 miles north-east), Hampstead (4 miles north-west), Ruislip (14 miles west), Stockwell (3 miles south) and Orpington (13 miles south-east).
Around South Bank
Around South Bank, our work takes us to homes and buildings near Jubilee Gardens, The Hole In The Wall pub and The BFI Reuben Library, among other places. You will also find St Andrew's and St John's Church of England Primary School (less than half a mile east) and London Nautical School (under half a mile north-east). South Bank has its own railway station: London Waterloo station. Well-known places in the area include Florence Nightingale Museum (within half a mile south) and Royal Waterloo Hospital for Children and Women (under half a mile north-east). For a walk, there’s Barnsbury Wood and St. James's Park Lake.
Bathroom resealing in South Bank
Mr Mastic has more than 20 years’ experience of sealant work, and our applicators reseal bathrooms and kitchens across South Bank. We are fully insured ARBOMaster approved applicators, and every job carries our one-year guarantee. We work on wet rooms, baths and sinks & splashbacks, and common reasons people get in touch are a reseal done over the top of the old bead and leaking joints on a shower screen.
Much of London’s older housing is Victorian and Edwardian terraces, many of them now split into flats, and bathrooms were often squeezed into small rooms. Small, steamy rooms are where mould gets into sealant and grout fastest.
Big or small, you get the same one-year guarantee.

Can I do it myself?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
When something else is needed
We’ll always be straight with you, so here’s what new sealant won’t do:
- A tray that rocks until it’s re-bedded
- A cracked shower tray or bath (that needs repair or replacement)
- Damage behind the tiles that needs a tiler
If in doubt, ring 0345 464 0079 or email us and we will say what we think.

How to look after the new joints
After the cure time, these simple habits help:
- Don’t let bottles sit on the bead
- Wipe the sealant dry after showering
- Use gentle cleaners on the silicone
- Open a window or run the fan so the room dries
Have a look at the joints every few months. A small split or a corner lifting is easy to spot, and if anything looks wrong, just ring 0345 464 0079 or drop us an email.
Each shower pushes a little more water through a failed joint. Over time that water reaches floors, walls and ceilings. Resealing early stops it.
How the visit works
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes around two hours for one bath or shower, longer for a whole bathroom. For a job in South Bank, 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.
- 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.
- Joints are degreased and any mould is treated.
- With the joint dry, and any bath loaded with water, a single bead of anti-fungal silicone is applied.
- We tool the bead to a neat finish and give you the cure time, normally around 24 hours.
Getting ready for the visit
- Mention if the joints have been sealed before
- On commercial sites, let us know about site rules
- Where the joints are inside, avoid wetting them before we arrive

When to call us in South Bank
Sealant laid on a damp, dusty or greasy joint never bonds properly. Soap residue, oils and leftover silicone film all get in the way, and a joint that looked fine soon begins to come away.
People generally contact us after spotting one of these:
- Water escaping at the shower enclosure
- Splits where the tray meets the wall
- Water getting behind the kitchen upstand
- New sealant laid over old sealant that is now lifting
As a London address, South Bank can be tricky for parking: let us know about parking bays, permits or a driveway.
Questions to ask before you book
- Which sealant they’ll use, and why
- Whether they seal over old material or remove it
- What happens if the job turns out different
- What the quote includes, VAT included or not
For landlords and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Letting agents often deal with us directly. Tell us the address, the job and how access works and we will give you a quote.
