Different surfaces, different methods
Baths
A bath shifts slightly every time it’s filled, so we fill it with water before sealing. That way the joint is laid with the bath at its heaviest and is not stretched when it’s used.
Shower trays & enclosures
Shower trays are sealed to the wall, and enclosures are sealed to the tray and tiles. Both get soaked every time the shower runs, so each is cut out and renewed with anti-fungal sanitary silicone.
About our bathroom resealing in Plumstead
With over 20 years in the trade, we reseal baths, showers and kitchens in homes across Plumstead. We’re fully insured ARBOMaster approved applicators, and the work comes with a 12-month guarantee. We work on sinks & splashbacks, wet rooms and shower trays & enclosures, and people most often call us about water escaping at the shower enclosure and gaps where the bath or tray has moved.
Much of London’s older housing is Victorian and Edwardian terraces, many of them now split into flats, with bathrooms fitted into whatever space was available. Small, steamy rooms are where mould gets into sealant and grout fastest, and homes in Plumstead are no different.
The work is covered for a year after we finish. If anything is not right with it, phone 0345 464 0079 or send us an email.

Honest limits
We will not take on work that won’t last, so here’s what sealant can’t put right:
- Cracks in the tray itself rather than the joint
- A bath or tray that moves because it is not properly supported
- Failed grout lines across the wall

FAQs for Plumstead
I live in a flat in Plumstead. Can a failed seal leak into the flat below?
Yes, and the first sign is often a stain on the ceiling below. Cutting out the old sealant and laying a new bead early stops it getting that far.
Is parking a problem for a job in Plumstead?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
How long does the new silicone need before I use the shower?
We give you the cure time before we leave, and it’s normally around 24 hours. Getting it wet too early can spoil the new joint.
How long does it take to reseal a bath or shower?
A single bath or shower takes about a couple of hours, old sealant removal included. A full bathroom and kitchen can take most of a day.
What colours of sealant can you use?
We can use white, clear or a colour to suit. Where the joint is on show, we match it to the surface.
Can I add another job to the visit?
Yes. More than one area can go on one quote.
Is the work guaranteed?
Yes. Our one-year guarantee covers every job, and we are fully insured.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
What happens if it’s left?
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. Skip those steps and even the best silicone fails early. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Plumstead, the repair is bigger than the sealant job would have been.
Doing several joints on one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll give you a clear quote for the lot.

Bathroom resealing around Plumstead
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. London’s water is hard, which leaves limescale on sealant, grout and taps.
Rented homes near Plumstead station change hands often, and a reseal between tenants is a quick way to make the bathroom and kitchen look cared for. Homes close to St John's Church include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Aftercare tips
To keep the joints looking good and working properly:
- Wipe the sealant dry after showering
- Clean with a mild bathroom cleaner and a soft cloth
- Check the joints every few months for splits or lifting
- Keep the fan on for a while after bathing
Clean the silicone with care: warm soapy water and a soft cloth do the job. Scourers and blades can nick the surface, and a nicked bead lets mould in sooner.
A few black dots in the silicone soon become a black line. Once it’s deep in the silicone, cleaning generally won’t remove it, and nearby grout often goes the same way. Replacing the sealant early keeps the job small.
