Bathroom resealing in Swiss Cottage
A bead that has gone black, split or come away shouldn’t be left until there’s a leak. A photo of the joints helps when you phone 0345 464 0079 or email us, and we will give you a clear price before any work starts. We work on shower trays & enclosures, sinks & splashbacks and kitchen worktops & upstands, and the jobs we see most are smears of silicone across the tiles and water getting behind the bath panel.
In much of London, period terraces have been converted into flats over the years, and bathrooms were often squeezed into small rooms. A compact bathroom that steams up every day is hard on silicone and grout, and homes in Swiss Cottage are no different.
All of our work is guaranteed for twelve months.

Swiss Cottage homes and their sealant
There are hotels and other places to stay in and around Swiss Cottage. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room. 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.
If you let a flat or house near South Hampstead station, fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay. If you look after a building such as The UCL Academy, we reseal washrooms and kitchens in schools and businesses as well as homes. Homes close to Church of All Souls include some older properties, and walls and floors in older homes can move, and sealant and grout show it first.
Swiss Cottage is about 1 mile south of Hampstead, in Greater London. Homes, rented property, offices and hotels in Swiss Cottage can book us for bathroom resealing, old or new, large or small. Every job comes with our one-year guarantee. Our Greater London coverage runs to 764 places, Swiss Cottage among them.

How we quote for bathroom resealing
You’ll get a clear quote before work begins. It’s based on:
- The amount of work
- The type of sealant required
- Whether old sealant or filler has to be cut out
- 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 drop us an email for an honest opinion and a quote.
What we need to know
What to tell us when you ask for a quote:
- How we’d reach the joints
- Photos by email, if that is easy
- If it’s domestic, commercial or a hotel
- What the problem is, such as mould, gaps, leaks or cracking
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 photos if that is easy.
DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Swiss Cottage questions
I let a flat near South Hampstead station. Can you help?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
Do you work in hotels near Swiss Cottage?
Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Is white the only colour available?
We can use white, clear or a colour to suit. Where the joint is on show, we match it to the surface.
Do you have insurance?
Yes, we are fully insured for every job we do.
How long does it take to reseal a bath or shower?
Allow half a day or less for one room, longer when the kitchen is included. You’ll know how long to expect before work begins.
Where is Mr Mastic based?
We are a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Why act early in Swiss Cottage
Mould removers can fade the surface of a stained bead, but mould that has grown into the sealant tends to return. The lasting answer is to remove the bead and start again. In a flat in Swiss Cottage, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why us?
- Approved under the ARBOMaster scheme
- More than 20 years in sealant work
- A sealant colour to suit the surroundings
- Anti-fungal sanitary silicone in wet areas

What else we do in Swiss Cottage
For landlords and businesses
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.
If you manage several properties in or around Swiss Cottage, several properties can be quoted together. Just tell us the addresses and what each one needs.
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Wipe the sealant dry after showering
- Wipe up water along the back of the worktop
- Look for lifting corners and small gaps now and then
- Keep the fan on for a while after bathing
In a kitchen, don’t let water sit along the back of the worktop. A dry joint lasts longer.
A few black dots in the silicone soon become a black line. When it has grown right through, it rarely cleans out. Catching it early keeps it a simple reseal.
How the visit works
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take half a day or less for one room, longer when the kitchen is included. In a London area like Swiss Cottage, 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.
- We start by protecting the area and stripping out the old bead.
- We clean and degrease the joint and treat any mould.
- We let it dry fully and fill the bath with water before sealing.
- New anti-fungal silicone goes on in a colour to suit and is tooled to a clean finish.
- We tidy up and give you the cure time, normally around 24 hours.
Preparing for the visit
- Clear items away from the joints we are working on
- On commercial sites, let us know about site rules
- Keep pets and children clear of the area while we work
