Bathroom resealing in Belsize Park, done properly
Mr Mastic has more than 20 years’ experience of sealant work, and our applicators reseal bathrooms and kitchens across Belsize Park. We’re ARBOMaster approved and fully insured, and the work comes with a 12-month guarantee. If you have water getting behind the kitchen upstand and black mould in the silicone that won’t clean off, we can help, whatever the surface.
Across London, a large share of homes are flats, conversions or mansion blocks, so a bathroom is often directly above a neighbour’s ceiling. In Belsize Park, that is a good reason to put tired sealant and grout right early.
We stand behind the work with a 12-month guarantee, so you are covered after we have gone.

What we are called out for in Belsize Park
Silicone does not last for ever. Daily water, heat and cleaning products slowly wear it down, and how long it lasts comes down to use, cleaning and ventilation.
It’s worth asking for a quote if you see:
- Gaps between the worktop and the wall
- Black spots spreading through the bead
- Lumpy, uneven sealant from a DIY attempt
- Cracked, shrunken or lifting silicone
Managing a site like Fine Arts College? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

What bathroom resealing looks like in Belsize Park
London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, which is why it’s worth fixing early. Belsize Park has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and can be done room by room.
Homes close to Church of St Mary the Virgin include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them. Belsize Park is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
Belsize Park is about 1 mile south-east of Hampstead, in Greater London. Jobs in Belsize Park get the same care as everywhere else we work: old sealant removed completely, careful preparation and a one-year guarantee. Our Greater London coverage runs to 764 places, and Belsize Park is one of them.
Work in NW3, NW5 and NW1 is quoted and booked the same way as anywhere else. If you need bathroom resealing at a property on Eton Road, Lawn Road and Ornan Road or anywhere close by, our applicators can take on the job.

Different surfaces, different methods
Baths
Baths move more than any other fitting, 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.
Kitchen worktops & upstands
Kitchen joints need more degreasing than bathroom ones, since cooking leaves a film that stops silicone sticking. The extra cleaning is what makes the bead last.
FAQs for Belsize Park
Do you work for landlords with property near South Hampstead station?
Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.
Could a tired shower seal in my Belsize Park 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 is down. A proper reseal before the leak starts is the easy fix.
How much does bathroom resealing cost in Belsize Park?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We’ll tell you what we are using and why.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or drop us an email.
How long does a bath or shower reseal take?
One bath or shower is around two hours’ work, old sealant removal included. A whole bathroom plus the kitchen may take most of the day.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Are you fully insured?
Yes. We are fully insured.
What we cannot put right
We will not take on work that will not last, so these are the limits:
- Loose or hollow tiles, or failed tanking behind them
- Cracked or missing grout between tiles (that is regrouting)
- A bath or tray that moves because it isn’t properly supported
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think before you book.
Surfaces we seal
- Baths
- Wet rooms
- Sinks & splashbacks

Landlords, agents and businesses in Belsize Park
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will give you a quote.
Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Places near Belsize Park
What else we do in Belsize Park
How the visit works
On the day, we look over the joints with you first, so you know exactly what we are doing. Surfaces next to the work are protected before work begins. Most jobs take half a day or less for one room, longer when the kitchen is included. In a London area like Belsize Park, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.
- First, each joint is checked for movement and signs of water.
- Every trace of the old bead is removed, including the thin smear on the tiles.
- Joints are degreased and any mould is treated.
- With the joint dry, and any bath loaded with water, a single bead of anti-fungal silicone is applied.
- The bead is tooled smooth and you are told the cure time, usually around 24 hours.
How to prepare
- Move anything stored near the joints
- Mention if the joints have been sealed before
- Mention any sign-in or site rules at work premises
