South Bank Commercial Sealant
Sealant work for offices, hotels, washrooms and commercial buildings for homeowners, landlords and businesses in South Bank. Fully insured, ARBOMaster approved and guaranteed for a year.
- Tired sealant ahead of a health and safety audit
- Split sealant around staff kitchen worktops and sinks
- Water marks on ceilings under bathrooms
The process
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes as long as the scope needs, from one welfare room to a full building. In South Bank, 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 agree a programme with you: which rooms, in what order, at what times.
- Tell us what paperwork your site needs, and we confirm what we can supply before any work starts.
- In each room, the old bead comes out and the joint is cleaned and treated.
- We reseal with the right product for each joint.
- Each finished area is checked with you and given a cure time.
How to prepare
- Mention if the joints have been sealed before
- Keep pets and children clear of the area while we work
- Mention any parking rules near the property

Tell us what paperwork your site needs, such as RAMS or insurance details, and we will confirm what we can provide.

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. Where a building in South Bank needs to stay open, work can be planned outside normal hours.

Signs you need commercial sealant in South Bank
Shower trays and baths in busy buildings move more: different weights, constant use and daily cleaning. If a tray flexes, the sealant around it splits.
Keep an eye out for any of the following:
- Split sealant where wet room floors meet walls
- Washroom sealant that looks dirty however often it’s cleaned
- Leaks from showers into rooms or ceilings below
- Mouldy bathrooms flagged at a tenancy check
If you look after a church, hall or community building such as St John's Church, halls and community kitchens see heavy use, and their sealant shows it.
Questions to ask before you book
- What guarantee comes with the work
- What insurance they hold
- Whether you can choose the colour
- How the surfaces are prepared before sealing
What sealant work can’t fix
We’d rather tell you now than do work that will not last, so these are the limits:
- Damaged sanitaryware that needs replacing
- A broken extractor fan behind the mould problem
- Leaking pipework, valves or wastes (a plumber’s job)
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly before you book.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Get split or lifting joints looked at early
- Note the date each area was done
- Add sealant to your planned maintenance checks
- Encourage users to squeegee shower walls
Squeegees in guest and staff showers help: less water sits on the joints between uses.
Mould in shared washrooms gets noticed and talked about. Left long enough, it spreads through the bead, and only replacement fixes it.
Commercial sealant around South Bank
South Bank has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. London’s water is hard, which leaves limescale on sealant, grout and taps.
For landlords with property near London Waterloo station, sealant work can be quoted for a single flat or a whole portfolio. If you look after a building such as Oasis Academy Johanna, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.

Landlord and commercial work in South Bank
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Why it’s worth doing now in South Bank
Replacing a whole washroom takes time, money and several trades. When the fittings are sound, renewing the sealant brings it back with far less upheaval. If something else is wrong, we will say so. In London conversions, one flat’s bathroom is often above another flat’s ceiling, 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 for homes in South Bank.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
