Bathroom resealing in St Mary Cray, done properly
A fresh bead of silicone changes how a bathroom looks more than most people expect. Mouldy silicone makes even a new bathroom look neglected, and a neat new joint puts that right in a short visit. It also seals the gaps that let water behind the bath. Typical jobs include leaking joints on a shower screen and water getting behind the bath panel, on sinks & splashbacks, baths and kitchen worktops & upstands.
London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. In St Mary Cray, bathroom resealing is as much about a room looking cared for as about keeping water out.

DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
The process
Most of a good job is in the preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a couple of hours for one bath or shower, or most of a day for a full bathroom and kitchen. In St Mary Cray, flats, stairs and shared entrances are part of the routine. 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.
- 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.
Preparing for the visit
- Clear items away from the joints we are working on
- Tell us about any water getting in
- Mention any parking rules near the property

Advice
St Mary Cray homes and their sealant
London’s water is hard, which leaves limescale on sealant, grout and taps. London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, so tired sealant is best dealt with early.
Homes close to Church of St Mary include some older properties, and bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. For site and facilities teams at buildings such as Poverest Primary School, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.

Questions from St Mary Cray
Can parking be tricky for a visit in St Mary Cray?
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.
I let a flat near St Mary Cray station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Can you get rid of the black mould in my sealant?
Yes, we replace the mouldy bead. Cleaning products may lighten it, but the lasting fix is new anti-fungal silicone on a clean, treated joint. Airing the room well helps stop it returning.
How much does bathroom resealing cost in St Mary Cray?
Size, access and the old material all affect the cost. Ask us for a quote and we will talk you through it.
Do you have insurance?
Yes, we’re fully insured for every job we do.
Where is Mr Mastic based?
We’re based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Do you need bathroom resealing in St Mary Cray?
Silicone needs a clean, dry surface without any grease to stick to. Soap residue, oils and leftover silicone film all get in the way, and a joint that looked fine soon begins to come away.
These are the problems we’re asked about most:
- Black mould in the silicone that will not clean off
- New sealant laid over old sealant that is now lifting
- Leaking joints on a shower screen
- A joint torn by a bath that flexes
For landlords with property near St Mary Cray station, a reseal between tenants is a quick way to make the bathroom and kitchen look cared for.
What your quote should include
- Who does the work, and how experienced they are
- What product goes in the joint
- How the joint is cleaned and prepared
- Whether all the old sealant comes out first
For landlords and businesses
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.
Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
What happens if it’s left?
A clean new bead makes a room look cared for, which matters if you are letting a property or selling it. Lumpy sealant with smears on the tiles has the opposite effect, and it’s harder to put right later. 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 St Mary Cray, the repair is bigger than the sealant job would have been.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.

What the job involves on each surface
Kitchen worktops & upstands
Laminate worktops swell if water gets into the core. A sound joint along the back edge stops that, as long as the worktop itself is firmly fixed.
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.
