Bathroom Resealing in Norbury
Baths, showers and worktops in Norbury need attention? We remove the old material, prepare the joints and seal them properly, with a 12-month guarantee.
- Water getting behind the kitchen upstand
- Water escaping at the shower enclosure
- Cracked, shrunken or lifting silicone
Different surfaces, different methods
Shower trays & enclosures
The vertical joint where a screen profile meets the wall is a common leak point. It’s resealed along with the tray joints, sealing the side the enclosure’s instructions call for.
Baths
Acrylic baths give a little under load, while steel and cast iron baths move less but still settle when full. Loading the bath with water before sealing allows for it.
How we handle bathroom resealing in Norbury
Across Norbury, the joints we reseal are the ones that fail in any home: bath edges, tray joints, basin backs and kitchen upstands. Each one is stripped, cleaned and dried before new silicone goes in. Typical jobs include black spots spreading through the bead and damp behind the bath or under the tray, on basins & vanity units, shower trays & enclosures and kitchen worktops & upstands.
London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. For a bathroom or kitchen in Norbury, getting the joints right keeps water where it belongs and the room looking clean.
All our work comes with our 12-month guarantee.

What bathroom resealing looks like in Norbury
London’s water is hard, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. Norbury 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.
As a London address, Norbury can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. For site and facilities teams at buildings such as Kensington Avenue Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

What affects the cost of bathroom resealing
There’s no set price list, because jobs vary so much. The quote depends on:
- When we can work, for business premises
- Access and height
- The type of sealant required
- The number of rooms or windows
What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.
Asking for a quote
You don’t need to know the technical terms. It helps if you can tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- If it’s domestic, commercial or a hotel
- Access, such as stairs, a lift or height
- If someone has resealed it before
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that’s easy.
What sealant work can’t fix
We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:
- A tray that rocks until it’s re-bedded
- Loose or hollow tiles, or failed tanking behind them
- Cracked or missing grout between tiles (that is regrouting)
If in doubt, call 0345 464 0079 or email us and we will say what we think before booking.
Joints and surfaces we work on
- Shower trays & enclosures
- Kitchen worktops & upstands
- Basins & vanity units
- Wet rooms
- Sinks & splashbacks
- Baths
Signs you need bathroom resealing in Norbury
Sealing over old silicone is one of the commonest mistakes we find. Fresh silicone can’t grip the old bead underneath, so it lifts, lets water in and traps mould underneath.
Any of these means the joints need attention:
- Two layers of silicone, both failing
- A bead that has pulled away from the tiles
- Black mould in the silicone that won’t clean off
- Splits where the tray meets the wall
For an older house near a landmark such as St Oswald, timber floors under older bathrooms flex, so joints need a sealant that moves with them.
What to look for in a quote
- Who does the work, and how experienced they are
- What happens if they find a problem under the old sealant
- How the colour is chosen
- How the surfaces are prepared before sealing
How the visit works
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and tidy away. Most jobs take half a day or less for one room, longer when the kitchen is included. 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.
- We cut away the old sealant and clean off what’s left.
- We treat any mould and let the joint dry properly.
- Baths are filled first, then anti-fungal sanitary silicone is applied in a colour to suit.
- The joint is finished neatly and we explain when it can get wet.
Getting ready for the visit
- Keep children and pets away from the work area
- Let us know about parking restrictions
- Mention any sign-in or site rules at work premises

Norbury: your questions answered
Can worn sealant in a flat in Norbury cause a leak downstairs?
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. It’s far simpler to replace tired sealant early than to deal with a neighbour’s ceiling.
Do you work for landlords with property near Norbury station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
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.
When can I use the bath or shower again?
After around 24 hours in most cases. You will get the exact cure time before we leave.
Can you reseal around my kitchen sink and worktop?
Yes. Where it’s needed by the sink, we use a food-safe sealant.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator.
Landlords, agents and businesses in Norbury
Whether it’s one flat or a portfolio, the work is the same standard: 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’ll quote.
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, provided the bath, tray and tiles are in good order. If something else is wrong, we’ll tell you. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Norbury, the repair is bigger than a sealant job.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
