Bathroom resealing across NW5: what to expect
The secret of a lasting bead is the preparation. The old sealant is removed to the last smear, then the joint is cleaned, degreased and treated for mould. Only once it’s dry does the new bead go on. We work on wet rooms, sinks & splashbacks and basins & vanity units, and people most often call us about gaps between the worktop and the wall and leaks into the floor or ceiling below.
We keep the work tidy and contained to the area we are working on. Expect the work to take half a day or less for one room, longer when the kitchen is included.
- First the area is protected and every bit of old sealant removed, including the film left on the tiles.
- Next, the joint is cleaned and any mould is treated.
- Once it’s dry, any bath is filled so the bead is laid with it at its heaviest.
- We apply anti-fungal sanitary silicone in one even bead and tool it neatly.
- We clear away and tell you when it can get wet, usually after around 24 hours.

Where we work in NW5
Our bathroom resealing work across NW5 covers homes, rentals and businesses, in Kentish Town, Chalk Farm and Tufnell Park and well beyond. Wherever the job is, all the old material comes out before anything new goes in.
London and the South East are among the drier parts of the UK, but outdoor sealant still needs a dry day and clean surfaces, so outside work in NW5 is planned around the forecast.
Kentish Town: For site and facilities teams at buildings such as Holy Trinity and Saint Silas CofE 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. As a London address, Kentish Town can be tricky for parking: let us know about parking bays, permits or a driveway.
What affects the quote in NW5
For a quick quote, just ask. What matters most is:
- When we can work, for business premises
- How many areas need sealing
- How much old sealant there is and how hard it is to remove
- The product the joint needs
Combining jobs into one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.
What we need to know
To make quoting easier, let us know:
- Access, such as stairs, a lift or height
- Pictures of the joints, sent by email
- The rough size of the job
- The type of property
Getting a quote is simple: let us know the job and the location. Photos by email help us understand the job, and we will take it from there.
Why act early?
A quick bead over the top of the old one might look better for a while, but it will not bond. It lifts, traps water and grows mould behind it, and the next reseal means two layers to cut out.
What your quote should include
- Which sealant they’ll use, and why
- How long the guarantee is
- How the colour is chosen
- How long to leave it before use
Landlords, agents and businesses in NW5
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Different surfaces, different methods
Baths
Baths move more than any other fitting, so we fill it with water before sealing. The joint is then laid with the bath at its lowest point.
Basins & vanity units
A vanity top has a joint along the wall and sometimes at the sides. If water gets in, the cabinet underneath can swell, so a neat, continuous bead matters.
NW5: your questions answered
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
My sealant has gone black. Can you sort it?
Yes, we can. We strip the bead, treat the joint and lay new anti-fungal silicone.
Do you reseal kitchen worktops and sinks too?
Yes. Kitchen joints get extra degreasing before the new bead goes on, then we reseal in a colour to suit.

Only a few details: where it is, what you’ve noticed and how we reach it. Then ring 0345 464 0079 or email us.
