Washroom sealing near Fishbourne

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

When to bring in a specialist

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Washroom sealing in Fishbourne, done properly

In healthcare and care settings, sealing is part of keeping surfaces cleanable. We work to your organisation’s estates and infection-control requirements and any site permits. Any records you need are confirmed with the quote. We work on kitchens and tea points, vanity units and basins and accessible toilets and changing rooms, and the failures we are asked to look at most are users noticing mouldy joints and gaps where vanity tops meet the wall. Most enquiries from Fishbourne start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Smaller places such as Fishbourne still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

Our workmanship is guaranteed for 12 months, in Fishbourne as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Fishbourne: questions and answers

Is Fishbourne too far out for you?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Will you work in a care home in Fishbourne without moving residents out?

Yes, with the manager deciding the order and timing of rooms. Any site rules, from signing in to infection control, are agreed before we start.

Is there a guarantee on the work?

Our workmanship has a 12-month guarantee backed by public liability insurance.

Is any job too small?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, let us know and we’ll send them with the quote.

How do you deal with asbestos in old sealant?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

Can weather delay the job?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

After the work

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Include joints in routine washroom inspections
  • Act on the first split you see at a shower tray
  • Don’t leave trays and floors sitting wet
  • Tell us about infection-control or permit rules before we quote

Keep extract fans working and vents clear. A room that stays damp will grow mould on almost anything so report fans that aren’t working to your building services team.

Small numbers of failed joints are quick to phase in. Left until every washroom is affected, it becomes a bigger programme and more closures to manage.

Surface by surface

Showers and trays

In staff, hotel and changing-room showers, the tray joint and wall corners take the hardest use. Every joint is stripped, degreased, dried and given a new bead.

Urinals and WC pans

The joint between a pan and the floor is easy to overlook. They are checked with everything else.

Keeping Fishbourne washrooms open while we work

With the shore within about 2 miles, Fishbourne counts as a coastal location, and seaside hospitality usually has a peak season that works washrooms hard. Showers and en suites in constant use are where silicone moulds and splits first, so resealing in the quieter months keeps rooms ready. There are two care or nursing homes within about 2 miles of Fishbourne. In care settings, wet rooms, assisted bathrooms and en suites rely on clean, sound sealant. Each room is kept out of use only as long as the sealant needs.

For a hall at a building such as St. Edmund's Church, resealing the kitchen and toilets can be fitted between bookings. If you manage an office at a site such as Wootton Business Park, 1.9 miles south-west of Fishbourne, the washrooms and tea points can be done a floor at a time.

Our process

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes half a day to a day per washroom, depending on the number of fittings, and we clear our waste as we work. Smaller jobs around Fishbourne can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. We agree which washrooms close and when.
  2. Leaks, loose panels or damp are pointed out first.
  3. Old sealant is stripped and the faces prepared.
  4. The right sanitary or food-safe sealant is applied.
  5. We confirm reopening times for each washroom.

Getting the site ready

  • Clear stock, furniture or equipment away from the joints
  • Tell staff and tenants when we will be in
  • Confirm the product named in the specification

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, phone 01277 525 020 or send details through our quote form.

What happens if it’s left?

Leaving the job until a shutdown often means living with it for months. Phasing lets it happen now, with facilities kept in use. Older rural buildings around Fishbourne move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.

Why us?

  • Fixed quotes based on photos, drawings or a visit
  • One phone line for London, the South East and Scotland
  • Workmanship guaranteed for 12 months
  • A Constructionline member, so easy to vet

When to call us in Fishbourne

We often find acrylic caulk or general-purpose sealant in joints that should have sanitary silicone. They aren’t made for constant wetting and they discolour and fail early.

Typical triggers for a call:

  • A new bead over an old one coming away
  • Shower tray joints that have opened up
  • Open joints along basins and vanity units
  • Black mould inside silicone joints that cleaning can’t shift

Healthcare washrooms on sites such as St Mary's Hospital, 3.9 miles west of Fishbourne, are resealed area by area, under the site’s own infection-control rules.

Questions to ask before you book

  • How they handle RAMS and site documents
  • Can the work be phased to keep areas open?
  • Their approach to joint depth and backing
  • Do they follow the manufacturer’s priming guidance?
