Commercial sealant in Botany Bay
Wet areas get anti-fungal sanitary silicone, and kitchens get a food-safe product where it’s needed. We use sealants from Arbo and Everbuild, chosen to suit each joint. We are often asked to deal with too many rooms to reseal without closing the building and mouldy washroom sealant that staff and guests notice, across retail & leisure sites, student & care accommodation and welfare facilities.
Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, whether that’s washroom resealing or fire-rated sealant around service openings. Out-of-hours working can be arranged where a building in Botany Bay can’t close.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
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.
Looking after it afterwards
After the cure time, these simple habits help:
- Log resealing so you know what’s due
- Include the silicone on your room checklists
- Check extract fans are actually running
- Ask cleaners to go gently on the silicone
Each room is handed back with its cure time, which is usually around 24 hours. Pass it on to housekeeping or cleaners so the new sealant is not wetted or scrubbed too soon.
Rooms out of use cost a hotel or landlord money. Small sealant faults caught early can be fixed between bookings or tenancies, before they become leaks that take the room out of use.
Landlords, agents and businesses in Botany Bay
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from a few hours to several days, depending on the number of rooms. In Botany Bay, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- 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.
- We lay the right sealant for each area, with anti-fungal silicone in wet rooms.
- Rooms are checked and returned with a cure time so staff know when to use them.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Mention if the joints have been sealed before
- Mention any parking rules near the property

Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Do you offer different sealant colours?
We help you choose a colour that suits. The product needed can limit the range.
How long does commercial sealant take?
Most jobs take anything from a few hours to several days, depending on the number of rooms. We’ll confirm how long when we quote.
What commercial sealant looks like in Botany Bay
London has hard water, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in. Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange.
Schools such as St. John's Senior School are buildings too, and sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours. As a London address, Botany Bay can be tricky for parking: let us know about parking bays, permits or a driveway.

Leave it or put it right?
A quick bead over the old sealant might get a room back in use today, but silicone doesn’t bond to silicone, so it lifts. Doing it properly once is less disruptive than doing it badly twice. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.

Common problems we fix in Botany Bay
Internal washrooms and en suites without a window rely entirely on extraction, and where extraction is poor, damp hangs around. That is when black mould sets into the bead.
Most people get in touch when they notice something like this:
- Split sealant around staff kitchen worktops and sinks
- Tired sealant in let properties
- Repeated reseals that don’t last
- Joints that need doing before an inspection or audit
