Advice
When to bring in a specialist
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Sanitary sealant for Upminster buildings
London offices and hotels typically can’t close all their washrooms at once, which is why the work is split into phases agreed in advance.
Schools such as Upminster Junior School have toilets, changing rooms and kitchens that are best resealed in the holidays. Healthcare washrooms on sites such as St George's Hospital (to the south-west of Upminster) are resealed area by area, under the site’s own infection-control rules.

Different surfaces, different methods
Basins and vanity tops
Basin joints get wet every time someone washes their hands, so the joint to the wall and around each bowl fails early. We remove the old bead and lay a fresh one of sanitary silicone.
Wet-room floors and floor-to-wall joints
Changing rooms and accessible showers often have wet floors, so their perimeter joints get close attention.
Common questions from Upminster clients
Do you work in London buildings with loading restrictions?
Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method. The ULEZ covers the whole of Greater London, which we allow for
Can you work on a hospital site such as St George's Hospital?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Are you insured?
Yes. We’re fully insured, and the certificate can go with your quote.
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators, as many construction sites ask for.
How long do sealant joints last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
How many days will you need on site?
The duration is planned around your programme and the access we’re given. We’ll give you an estimate of time on site when we quote.
How long before the toilets can reopen?
That varies with the sealant and the room temperature. Each room gets its own reopening time from us, and signs stay up until then.

Why act early in Upminster
Leaving the job until a shutdown often means living with it for months. With phasing, the work can go ahead while most facilities stay open. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

When to call us in Upminster
Panels and vanity units move slightly in use and trays shift slightly with each user. A bead that can’t cope with the movement splits along one edge.
Most enquiries start with something like this:
- Failed joints along IPS and cubicle panels
- Failed sealant in a tea point or staff kitchen
- Failed sealant behind washroom basins
- Stained sealant around pans and urinals
Church halls and community buildings, such as those at Church of St Laurence, have kitchens and toilets used by many groups, and their sanitary sealant works hard.
