Bathroom Resealing in Silvertown

How we handle bathroom resealing in Silvertown
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 clean white or clear joint fixes it quickly. Just as important, it closes the gaps water would otherwise get through. Common call-outs are for water escaping at the shower enclosure and shrunken sealant along the back of a worktop, on wet rooms, kitchen worktops & upstands and sinks & splashbacks.
London homes include a lot of flats, conversions and mansion blocks, and many bathrooms sit right above someone else’s ceiling. In Silvertown, that’s 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.

What we do, step by step
At the end, we look at the finished work together. The visit itself normally takes two to three hours for a typical bath, depending on how much old sealant there is, depending on how much there is to do. In Silvertown, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- Protection goes down around the bath, shower or worktop.
- Old sealant is sliced away and the residue removed.
- Mould is treated, then the joint is left to dry thoroughly.
- Baths are filled first, then anti-fungal sanitary silicone is applied in a colour to suit.
- We finish the joint, clear up and tell you how long to leave it before it gets wet.
How to prepare
- Tell us if parking is tricky
- Plan for the work area to be out of bounds to pets and children
- Where the joints are inside, avoid wetting them before we arrive

Questions from Silvertown
Is parking a problem for a job in Silvertown?
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.
Do you take on hotel work around Silvertown?
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 take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
What colours of sealant can you use?
There’s a choice: white, clear and colours to suit tiles and worktops. We will talk it through when we quote.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Where are you based?
We work from Crawley. Our applicators cover Silvertown.
Is it OK to put new sealant on top of the old bead?
No, and it’s one of the main reasons reseals fail. We cut out all of the old sealant, clean the joint and start again.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
Why act early in Silvertown
Most of the work in a good reseal happens before any silicone goes on: cutting out every trace of the old bead, cleaning, treating mould and letting the joint dry. Without that preparation, the new bead will not last. In a flat in Silvertown, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
Why choose Mr Mastic in Silvertown
- We leave the area clean and tidy
- Quality sealants from Arbo and Everbuild
- Approved under the ARBOMaster scheme
- Domestic, commercial and hotel work

Looking after it afterwards
A little care helps the new joints last. Our advice:
- Keep scourers and sharp tools away from the bead
- Keep the fan on for a while after bathing
- Wipe the sealant dry after showering
- Keep an eye on the corners, where splits start
Treat the new bead gently when you clean: a mild bathroom cleaner and a soft cloth is enough. Scourers and blades can nick the surface, because a damaged bead gives mould a foothold.
Worktop joints fail quietly. Splashes run behind the back edge and soak into the worktop, where it can make the board swell. Resealing before that happens protects the worktop.
Bathroom resealing in Silvertown: local notes
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. There are hotels and other places to stay in and around Silvertown. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.
For landlords with property near Custom House station, a reseal between tenants is a quick way to make the bathroom and kitchen look cared for. In the older streets around St Barnabas' Church, walls and floors in older homes can move, and sealant and grout show it first. Managing a site like Britannia Village Primary School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.
Surface by surface
Kitchen worktops & upstands
Kitchen joints need more degreasing than bathroom ones, because cooking grease stops sealant bonding. Proper degreasing is what helps the new joint last.
Shower trays & enclosures
There are generally two jobs in a shower: the tray-to-wall joint and the enclosure joints. Both take water every day, so each is cut out and renewed with anti-fungal sanitary silicone.
Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
