About our commercial sealant in Kings Cross
In showers and washrooms we use anti-fungal sanitary silicone, with a food-safe sealant by kitchen sinks where needed. Products include Arbo and Everbuild sealants, chosen to suit each joint. We work on office washrooms & kitchens, student & care accommodation and hotel bathrooms, and the jobs we see most are leaking joints in shower rooms and changing areas and black, stained silicone in guest bathrooms.
London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, from washroom silicone to fire-rated sealant around pipes and cables passing through walls. Out-of-hours working can be arranged where a building in Kings Cross can’t close.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
What we cannot put right
To be straight with you, there are a few things sealant won’t fix:
- A broken extractor fan behind the mould problem
- Water damage behind the tiles that needs a tiler or builder
- Damaged sanitaryware that needs replacing
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.

The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours per area, with larger sites planned over several visits. For a job in Kings Cross, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- We start with a site walk to agree the rooms and the timing.
- Each area is protected and the old sealant cut out completely.
- We clean the joints, treat any mould and let them dry.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealants elsewhere.
- Each room is checked and handed back with its cure time.
Preparing for the visit
- Mention if the joints have been sealed before
- Keep pets and children clear of the area while we work
- For indoor joints, keep the area dry beforehand if you can

Why act early in Kings Cross
Room by room, the work is quick: it takes a few hours per area, with larger sites planned over several visits. After that, each area needs its cure time before use, so planning the order matters more than the hours on site. In a flat in Kings Cross, 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.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs. Ask us for a quote and we’ll go through it with you.

What commercial sealant looks like in Kings Cross
Kings Cross has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed. Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange.

For landlords with property near London Kings Cross station, sealant work can be quoted for a single flat or a whole portfolio.

What affects the cost of commercial sealant
We do not publish a price list, because jobs vary so much. The quote depends on:
- Whether there’s mould to deal with
- Which sealant suits the joint
- Whether the work is at height
- The size of the job
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first.

- What the problem is, such as mould, gaps, leaks or cracking
- Whether it’s a home or a business
- Pictures of the joints, sent by email
- Any previous sealing or DIY work
