How bathroom resealing works in N3
Mr Mastic has more than 20 years’ experience of sealant work, and our applicators reseal bathrooms and kitchens across N3. We’re fully insured ARBOMaster approved applicators, and every job carries our 12-month guarantee. Typical jobs include water getting behind the bath panel and a joint torn by a bath that flexes, across baths, sinks & splashbacks and basins & vanity units.
Every visit runs the same way: we check the joints, protect the area around them, do the work and tidy away. It generally takes around two hours for one bath or shower, longer for a whole bathroom.
- First, each joint is checked for movement and signs of water.
- The old silicone is cut out completely, along with the film it leaves on the tiles.
- Joints are degreased and any mould is treated.
- When the joint is dry, and a bath has been filled with water, the new silicone goes on.
- We tool the bead to a neat finish and give you the cure time, normally around 24 hours.

Honest limits
Some problems need a builder, plumber or other trade rather than us:
- A tray that rocks until it’s re-bedded
- Failed grout lines across the wall
- Loose or hollow tiles, or failed tanking behind them
Different surfaces, different methods
Baths
Most bath leaks begin along the long edge, especially under a shower. It gets one smooth bead of anti-fungal silicone.
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, following the enclosure maker’s guidance on which side to seal.
What affects the cost of bathroom resealing
We do not publish a price list, because jobs vary so much. The quote depends on:
- Any working-time requirements on site
- How much old sealant there is and how hard it is to remove
- Whether the work is at height
- Mould in or behind the old joints
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or email us for an honest opinion and a quote.
What we need to know
When you contact us, it’s useful to know:
- What’s wrong with the joints now
- Any access issues, like height or stairs
- The rough size of the job
- Where the property is
Asking for a quote is easy: let us know what needs doing and where. A few photos by email make the job easier to understand, and we will come back to you with a quote.
Should I try it myself first?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
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.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Wait for the cure time we give you
- Never pick at the silicone with a blade
- Run the extractor fan during and after every shower
- Clean with a mild bathroom cleaner and a soft cloth
Keep bottles and razors off the sealant line, because they trap water against the silicone. A quick squeegee after showering keeps water from sitting on the joint.
Don’t wait for a refit to deal with failed sealant. Sealant is a maintenance item, like the paint on a window frame, and renewing it as soon as it fails protects everything around it.
FAQs for N3
Where is Mr Mastic based?
Our base is in Crawley, and we work across South East England, London and Scotland.
Do you cover N3?
Yes. We are based in Crawley and work across South East England, London and Scotland, and that includes N3.
Can I choose the colour of the sealant?
You’re not limited to white: clear, white and colours chosen to suit the room. We’ll talk it through when we quote.
Can new silicone go straight over the old?
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.
How do I get a quote for bathroom resealing in N3?
It depends on the job, so we quote each one individually. To get one, phone 0345 464 0079 or drop us an email with a short description of the job.
What should I tell you?
A short description and the location, plus photos if you have them. If we need more, we’ll ask.
Will the old sealant be removed?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
