Our process

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes a morning or so for a small washroom, longer where showers and changing rooms are included, and we clear our waste as we work. Several jobs near Hillyfields can be grouped on one trip. Tell us your site hours and we’ll plan around them.

  1. We agree which washrooms close and when.
  2. Leaks, loose panels or damp are pointed out first.
  3. Failed sealant and residue are stripped out.
  4. The right sanitary or food-safe sealant is applied.
  5. We give you a reopening time for every room.

Getting the site ready

Advice

Washroom sealing for commercial buildings in Hillyfields

Our washroom work covers offices, hotels, schools and colleges, leisure centres and gyms, clinics and care homes, along with staff kitchens and tea points. The products and the method are chosen for how heavily each space is used. Most enquiries involve sealant lifting along a tray edge and resealing that didn’t last because the old bead stayed, on accessible toilets and changing rooms, kitchens and tea points and IPS panels and cubicles. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Hillyfields is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Around Hillyfields, washroom work usually comes one building at a time. A list and photographs let us quote and plan so it’s done in one visit where possible.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

When to bring in a specialist

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.

Surface by surface

Changing rooms and gyms

Changing rooms in gyms and leisure centres stay wet and warm, so mould is a constant battle. We use anti-mould sanitary silicone throughout.

Wet-room floors and floor-to-wall joints

We seal the visible joints; we don’t install or repair waterproofing below and point it out if water appears to rise from below.

Maintenance after handover

To get the most from the new sealant:

  • Mention any site permits or estates rules at quote stage
  • Inspect washroom sealant regularly
  • Avoid scourers and harsh descalers on silicone
  • Leave signs up until the cure time is over

Ask your cleaning team to use gentle products and soft cloths on sealant. Strong acids, solvents and scourers wear the surface over time.

Leaks through tray and wet-floor joints can go unseen until a ceiling marks below. At that stage, boards or ceilings may need repair, so reseal when you first spot a split.

Toilets, showers and kitchens around Hillyfields

Hillyfields sits close to the coast, within about 2 miles, and coastal places often have hotels, guest houses and holiday accommodation with busy seasons. Bathrooms turned round daily in the busy months need sound, cleanable joints, so resealing in the quieter months keeps rooms ready. There are six care or nursing homes within about 2 miles of Hillyfields. Care home wet rooms and en suites are used every day and cleaned hard, which tells on the silicone. We plan the work with the manager so residents are disturbed as little as possible.

Colleges such as Totton College (to the south-west of Hillyfields) have toilets, changing rooms and catering kitchens that can be resealed around term dates. Staff changing rooms and patient toilets at places like Western Community Hospital, 1.2 miles south-east of Hillyfields, need cleanable, sound silicone. Halls of residence and teaching buildings at universities such as University of Southampton, 3 miles east of Hillyfields, are easiest to reseal during vacations.

Hillyfields is about 2 miles north-west of Regents Park, in Hampshire. Anywhere in SO16, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 723 places in Hampshire, large and small.

Postcode districts covered here: SO16 for washrooms and wet areas. Buildings on Maplin Road, Colne Avenue and Hayburn Road are within our area for washrooms and wet areas.

For managing agents and facilities managers

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Hillyfields can sit alongside others in a wider programme across Hampshire.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

Why act early in Hillyfields

A tired-looking washroom doesn’t always need a refurbishment. Where tiles, panels and fittings are sound, new sealant may be enough to put it right for now. In a smaller place such as Hillyfields, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.

Questions about Hillyfields

Can you take on a job at a hospital such as Western Community Hospital?

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

Do you work in occupied care homes around Hillyfields?

Yes. We agree rooms and times with the manager and work a few areas at a time. Any site rules, from signing in to infection control, are agreed before we start.

When can the area be used after sealing?

We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards, which many sites require.

Do you take on small jobs?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

How long will the new sealant last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

How long does a job like this take?

We plan the time on site around your programme and access. You’ll have an expected duration with the quote.
