Bathroom resealing for homes and businesses in Crouch End
With over 20 years in the trade, we reseal baths, showers and kitchens in homes across Crouch End. We are ARBOMaster approved and fully insured, and the work comes with a 12-month guarantee. We work on baths, sinks & splashbacks and wet rooms, and people most often call us about gaps where the bath or tray has moved and leaking joints on a shower screen.
Across London, a large share of homes are flats, conversions or mansion blocks, and many bathrooms sit right above someone else’s ceiling. That makes worn sealant and cracked grout in Crouch End more than a cosmetic job.
Our work is backed for twelve months, in Crouch End and everywhere else we cover.

Why act early in Crouch End
Fresh sealant smartens a bathroom or kitchen with very little disruption, which helps when a home is being let or put on the market. A smeared, uneven DIY bead does the opposite. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Crouch End, the repair is bigger than a sealant job.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.

When something else is needed
Sealant is not the answer to every problem, and we’ll tell you before work begins. It won’t solve:
- Water getting in through the grout rather than the sealant
- Movement from a bath with loose feet or no proper support
- A tray or bath that is cracked through
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.
What we seal
- Sinks & splashbacks
- Shower trays & enclosures
- Baths
- Wet rooms
- Basins & vanity units
- Kitchen worktops & upstands
What we do, step by step
We bring everything the job needs with us. After a quick look at the joints together, the area is protected and the work begins. It normally takes two to three hours for a typical bath, depending on how much old sealant there is. For a job in Crouch End, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- Protection goes down around the bath, shower or worktop.
- We cut away the old sealant and clean off what’s left.
- 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.
- The joint is finished neatly and we explain when it can get wet.
How to prepare
- Mention any leaks or damp you’ve noticed
- Mention any parking rules near the property
- Mention any sign-in or site rules at work premises

Surface by surface
Baths
Acrylic baths flex the most, and even steel and cast iron baths settle slightly when full. Loading the bath with water before sealing allows for it.
Shower trays & enclosures
Shower trays are sealed to the wall, and enclosures are sealed to the tray and tiles. Both take water every day, so each is cut out and renewed with anti-fungal sanitary silicone.
How we quote for bathroom resealing
Jobs vary more than people expect. The main factors:
- How easy the joints are to reach
- The old material and how stubborn it is
- When we can work, for business premises
- How much there is to do
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.
Helping us quote
When you contact us, it’s useful to know:
- Any access issues, like height or stairs
- Whether it’s a home or a business
- Any previous sealing or DIY work
- The rough size of the job
There’s no standard price list, as no two jobs are quite the same. Instead, we give you a clear price for your job. To arrange one, ring 0345 464 0079 or send us an email.

Crouch End questions
Is parking an issue for bathroom resealing in Crouch End?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Could a tired shower seal in my Crouch End flat affect the neighbours below?
Yes. In a flat, water from a failed bath or shower seal has only one way to go, and that’s down. Cutting out the old sealant and laying a new bead early stops it getting that far.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Do you remove the old sealant?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Where do you work from?
Mr Mastic is based in Crawley. Our applicators cover Crouch End.
Can tenants book the work?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Can you quote for more than one area?
Yes. Several rooms, windows or areas can go on one quote.
Can you get rid of the black mould in my sealant?
Yes. Mould inside the bead rarely cleans out for good, so we cut it out, treat the joint and reseal with anti-fungal silicone.
Do you need bathroom resealing in Crouch End?
Silicone doesn’t last for ever. Every shower, every splash and every wipe with a cleaner slowly wear it down, and how long it lasts comes down to use, cleaning and ventilation.
Signs it’s time to call us include:
- Cracked, shrunken or lifting silicone
- A messy, uneven bead from a previous reseal
- Shrunken sealant along the back of a worktop
- Two layers of silicone, both failing
Managing a site like Rokesly Infant & Nursery School? Then we reseal washrooms and kitchens in schools and businesses as well as homes.

How to look after the new joints
So the new joints stay in good condition:
- Wait for the cure time we give you
- Dry the bead with a towel now and then
- Dry worktop joints after washing up
- Check the joints every few months for splits or lifting
Wipe up standing water along the worktop joint. The drier the joint stays, the longer it lasts.
Small signs come before a leak: a corner lifting, a gap behind the bead, a dark line under the silicone or a damp patch on the ceiling below. Any of these means the joint needs attention.
