What sealant work can’t fix
Sealant solves a lot, but not everything, and we are upfront when that’s the case. These need a different solution:
- Water escaping beneath the floor rather than through a joint
- Leaking pipes, traps, wastes or cisterns, which need a plumber
- Mould caused by poor ventilation, which will return until the extract is fixed
If in doubt, phone 01277 525 020 or send details through our quote form and we will say what we think.

How we handle washroom sealing in Highfield
In a commercial washroom, sealant is usually the first thing to wear out. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day, and once mould grows into it, it can’t be scrubbed out. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. If you have stained or open joints at kitchen sinks and worktops and sealant laid over old silicone and now peeling, we can help. For commercial sealant work in Highfield, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
In and around places like Highfield, hospitality kitchens and toilets see heavy use in busy spells. Smooth, sealed joints at worktops, sinks and wall cladding make cleaning easier, using a food-safe product near food preparation.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Keeping Highfield washrooms open while we work
With the shore within about 3 miles, Highfield counts as a coastal location, and places by the sea often rely on visitors, so their hotels and holiday lets see heavy seasonal use. Heavy seasonal use is hard on shower and basin sealant, and the quieter months are the natural time to reseal. Highfield has two care or nursing homes no more than 2 miles away. In care settings, wet rooms, assisted bathrooms and en suites rely on clean, sound sealant. Work is agreed with the manager, around residents’ routines.
Student showers at universities like University of Southampton (to the south of Highfield) see more use than most, and their silicone shows it. For an occupier at a site such as Belgrave Industrial Estate, 0.7 miles to the east of Highfield, the canteen and welfare facilities need cleanable joints as much as any office.

On site: what to expect
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. If neighbouring businesses or buildings around Highfield need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.
- Every room is surveyed and the failed joints listed.
- The fixed quote sets out the rooms, the products and the phasing.
- The whole of the old bead is removed.
- Each joint is cleaned and left dry.
- New anti-mould sealant goes in and is tooled neat.
- Rooms reopen after the cure time.
Getting the site ready
- Tell staff and tenants when we will be in
- Point out parking and an unloading spot
- Send any specification or drawings in advance
Ask for a quote
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
Advice
Should maintenance staff do it?
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Different surfaces, different methods
IPS and cubicle panels
Panel systems meet walls, floors and vanity tops at sealed joints. They stop water reaching the panel boards.
Wet-room floors and floor-to-wall joints
Wet-room floors and the joints where flooring turns up the wall need to stay sound. We reseal the floor-to-wall junctions and around drains where sealant is used.
What we are called out for in Highfield
Warmth, moisture and soap residue are exactly what mould needs, and sealant joints trap all three. Anti-mould additives help, but in a poorly ventilated room mould can still take hold eventually.
If one of these sounds familiar, it’s time for a closer look:
- Gaps where vanity tops meet the wall
- Shower tray joints that have opened up
- Open joints at the base of cubicle panels
- Sealant stained black around basins and showers
Healthcare estates like Royal South Hants Hospital, 1.2 miles to the south of Highfield, expect contractors to follow their permits and cleaning rules in every washroom.

For managing agents and facilities managers
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.
