Common questions in Millwall
I live in a flat in Millwall. 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. Replacing the sealant and grout before that happens is much less trouble than repairing a neighbour’s ceiling.
Is parking an issue for bathroom resealing in Millwall?
Parking in Millwall, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
Where do you work from?
We’re based in Crawley, West Sussex, and we work across South East England, London and Scotland.
What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. Then phone 0345 464 0079 or drop us an email.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
Is the work guaranteed?
Yes, for 12 months. Looking after the joint as we suggest helps it last.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
I rent my home. Can I book you?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
Bathroom resealing for homes and businesses in Millwall
Resealing is a small job that makes a big difference. Black, patchy sealant makes clean tiles look tired, and a neat new joint puts that right in a short visit. It also seals the gaps that let water behind the bath. If you are dealing with cracked, shrunken or lifting silicone and failed sealant on the screen profile, we can put it right.
London homes include a lot of flats, conversions and mansion blocks, and many bathrooms sit right above someone else’s ceiling. In Millwall, that’s a good reason to put tired sealant and grout right early.
Every job is covered by our one-year guarantee.

What sealant work cannot fix
A few problems are outside what sealant work can do:
- A tray or bath that is cracked through
- Damage behind the tiles that needs a tiler
- A tray that rocks until it’s re-bedded
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly.
What we seal
- Shower trays & enclosures

- Kitchen worktops & upstands

Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
Landlord and commercial work in Millwall
If you manage several properties in or around Millwall, several properties can go on one quote. Just tell us the addresses and what each one needs, and photos by email help.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep scourers and sharp tools away from the bead
- Stick to a soft cloth and a mild cleaner
- Move toiletries away from the joint
- Dry the bead with a towel now and then
Wipe up standing water along the worktop joint and keep hot pans away from the silicone. The drier the joint stays, the longer it lasts.
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
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself normally takes a couple of hours for a single bath or shower, depending on the amount of work. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- We cover the area around the joints we’re working on.
- Old sealant is sliced away and the residue removed.
- Mould is treated, then the joint is left to dry thoroughly.
- Any bath is filled with water, then we lay a bead of anti-fungal silicone in white, clear or a matching colour.
- The joint is finished neatly and we explain when it can get wet.
How to prepare
- Mention if the joints have been sealed before
- Mention any leaks or damp you’ve noticed
- Tell us about access, such as stairs, a lift or high-level joints

Advice
What happens if it’s left?
Mould removers can fade the surface of a stained bead, but where mould is inside the silicone it normally comes back. Cutting it out and resealing with anti-fungal silicone is the fix that lasts. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

What bathroom resealing looks like in Millwall
Millwall has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and can be done room by room. London has hard water, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in.
Schools such as Harbinger Primary School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes. For landlords with property near Deptford station, fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay.

When to call us in Millwall
No sealant lasts indefinitely. Every shower, every splash and every wipe with a cleaner slowly wear it down, so its life depends on how the room is used, cleaned and aired.
Any of these means the joints need attention:
- Water getting behind the kitchen upstand
- Mouldy sealant that has gone black
- Failed sealant on the screen profile
- Lumpy, uneven sealant from a DIY attempt
In the older streets around Church of St Nicholas, timber floors under older bathrooms flex, so joints need a sealant that moves with them.
