Commercial sealant in Farringdon
Office kitchens, staff washrooms and welfare facilities need to be usable every working day. Early starts and out-of-hours work can be arranged to keep disruption down. Each area is handed back with its cure time. We work on student & care accommodation, retail & leisure sites and rental portfolios, and the jobs we see most are washrooms that need sorting before an inspection and tired sealant in let properties.
London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. In Farringdon, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
All of our work is guaranteed for twelve months.

Signs you need commercial sealant in Farringdon
Larger buildings move, and lightweight partitions flex more than masonry. Joints between different materials take the strain.
If you can see any of these, it’s time to have the joints looked at:
- Water marks on ceilings under bathrooms
- Split sealant where wet room floors meet walls
- Too many rooms to reseal without closing the building
- Split sealant around staff kitchen worktops and sinks
If you look after a building such as Charterhouse Square School, busy washrooms and kitchens can be resealed in phases so they stay open.
What to look for in a quote
- Whether the sealant suits the joint
- The length of the guarantee
- How long to leave it before use
- Whether all the old sealant comes out first
What we do, step by step
The work is kept neat and contained to the joints we’re treating. Expect the work to take as long as the scope needs, from one welfare room to a full building, and we explain the cure time before we leave. In Farringdon, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- Tell us the rooms, hours and site rules, and we will plan the programme.
- We go through your site’s paperwork needs, such as RAMS, before work begins.
- Old sealant is cut out room by room and joints cleaned and treated.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealant elsewhere.
- Rooms are handed back in order, each with its cure time.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Let us know if you’ve seen damp or leaks
- Let us know about earlier repairs to the joints

Why act early in Farringdon
First impressions are often made in the washroom. Mouldy silicone looks unhygienic, however hard housekeeping work, and cleaning rarely puts it right. Replacing it does. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in Farringdon.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

Looking after it afterwards
So the new joints stay in good condition:
- Get split or lifting joints looked at early
- Pass on the cure time to whoever cleans the rooms
- Use mild cleaners on sealant, not bleach or abrasives
- Keep a record of which rooms were resealed and when
Ask staff to report splits or lifting sealant early. A small gap caught quickly is a short fix, and if anything looks wrong, just ring 0345 464 0079 or drop us an email.
In a commercial building, a leak can quickly spread beyond one room: through floors, into ceilings and across into corridors. Early resealing keeps it from getting that far.
Can I do it myself?
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
Some sealant jobs are within reach of a careful DIYer, 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.
