Bathroom resealing in Nag's Head
Sealant is the soft line between a bath, shower or worktop and the wall. When it splits, shrinks or turns black, water gets behind it and into the wall or floor. Every trace of the old sealant is taken out and replaced with anti-fungal sanitary silicone. We work on sinks & splashbacks, baths and basins & vanity units, and the jobs we see most are shrunken sealant along the back of a worktop and black mould in the silicone that won’t clean off.
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.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Leave it or put it right?
Dealing with sealant early is a short job: it takes half a day or less for one room, longer when the kitchen is included. Left until water gets through, the job can grow to lifting panels, drying out and decorating. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Nag's Head, the repair is bigger than a sealant job.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.
Why us?

What the job involves on each surface
Sinks & splashbacks
Where a splashback meets the worktop, there’s a joint that catches every splash. We renew it in clear, white or a matched colour.
Kitchen worktops & upstands
Laminate worktops swell if water gets into the core. A continuous bead along the back keeps water out.
Bathrooms and kitchens in Nag's Head
In a London flat, water from a failed bath or shower seal can reach the neighbours below, which is why it’s worth fixing early. London has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
For an older house near a landmark such as St Joseph and St Padarn's Church, older homes can move a little, which is hard on rigid grout and tired sealant. For site and facilities teams at buildings such as Grafton Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes.

How the visit works
When we arrive, we start by going over the job with you, so you know exactly what we are doing. We protect the surfaces around the joints before work begins. Most jobs take a morning or an afternoon for most single baths and showers. In Nag's Head, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- We look at every joint first and check for movement or leaks.
- Every trace of the old bead is removed, including the thin smear 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, usually around 24 hours.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Plan for the work area to be out of bounds to pets and children
- Clear the area around the work

Honest limits
New sealant cannot fix everything, and we’ll tell you before we start. It will not solve:
- A leaking waste, trap or valve
- Loose or hollow tiles, or failed tanking behind them
- Movement from a bath with loose feet or no proper support
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly.
Surfaces we seal

What we are called out for in Nag's Head
Black mould is behind a lot of resealing. Steamy rooms that do not dry out give mould all the damp it needs, and mould that has grown into the silicone generally will not clean off.
People usually contact us after spotting something like this:
- Two layers of silicone, both failing
- Gaps between the worktop and the wall
- A messy, uneven bead from a previous reseal
- A bead that has pulled away from the tiles
Nag's Head is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
