Commercial washrooms in Broomer's Corner

Broomer's Corner is about 38 miles from central London. Office toilets in the commuter belt are in use from first arrivals to last departures, so we phase work to keep some facilities open.

Pupil toilets at schools like William Penn School take heavy daily use, and the holidays give the window to reseal. Halls linked to places like St Mary's Mission Church host groups all week, which is hard on kitchen and toilet sealant. For buildings on a site such as Crays Court (business park) (2 miles south of Broomer's Corner), washrooms and tea points can be resealed in phases through the working week.

Broomer's Corner is about 7 miles south-west of Horsham, in West Sussex. Any commercial site in Broomer's Corner is covered, for single jobs and planned programmes alike. We work across 373 places in West Sussex, large and small. Sites around Brighton have their own page, about 15 miles away.

We take on washrooms and wet areas across the RH13 postcode area, whatever the building. We cover commercial and managed buildings on Saucelands Lane, Sincox Lane and Hooklands Lane and the roads nearby.

Washroom sealing in Broomer's Corner, done properly

From one staff toilet in Broomer's Corner to washrooms across a whole estate, the route is the same: send details, get a fixed quote, we seal, guaranteed. Photos and a rough count of basins, urinals, showers and cubicles help us give a quick quote, or we can arrange a visit. We work on IPS panels and cubicles, showers, trays and wet room floors and accessible toilets and changing rooms, and the failures we are asked to look at most are gaps where vanity tops meet the wall and complaints from staff, guests or users about tired washrooms. For commercial sealant work in Broomer's Corner, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Community buildings around smaller places like Broomer's Corner have kitchens and toilets used by many people. Resealing sinks, worktops and WCs with anti-mould silicone keeps them clean and watertight.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What we can’t put right

Some faults sit outside our scope, and we say so rather than covering them up:

  • Condensation from failed extract fans
  • A dripping waste or valve behind a panel
  • Fittings that move too much to hold a bead

If in doubt, call the office on 01277 525 020 or send photos by email and we will say what we think.

Surfaces we seal

  • Kitchens and tea points
  • Showers, trays and wet room floors
  • Accessible toilets and changing rooms
  • Urinals and WCs
  • Vanity units and basins
  • IPS panels and cubicles

Should maintenance staff do it?

Redoing a failed joint typically costs more than getting it right at the outset, 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: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Leave it or put it right?

Sealing on top of old silicone saves nothing. It doesn’t bond, so it peels and traps dirt behind it. Full removal and proper cleaning is what makes the new joint last. Older rural buildings around Broomer's Corner move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

There’s no price list, because the scope varies so much from one building to the next. Call for a quote.

After the work

Regular inspection catches problems early. Specifically:

  • Report faulty extraction promptly
  • Include joints in routine washroom inspections
  • Respect the cure time before reopening each room
  • Tell us about infection-control or permit rules before we quote

Ask your cleaning team to use gentle products and soft cloths on sealant. Aggressive descalers, solvents and scouring pads shorten its life and give mould a start.

Water getting behind IPS panels and vanity units can swell the boards. After that, those parts need replacing rather than resealing.

Cost factors for washrooms and wet areas

Quotes vary with the job. Expect it to depend on:

  • Induction, permit and paperwork requirements
  • Distance, for remote addresses
  • Phasing around occupants
  • Removal of failed or old sealant

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

What to include in your enquiry

Whether it’s one area or a whole building, the same details help:

  • Rough lengths or quantities, or drawings if you have them
  • Any specification or named product
  • Clear photographs of the problem areas
  • Whether the building will be occupied during the work

For a fixed quote, call the office on 01277 525 020 or email us. You can also send details through our quote form.

Our process

Tell us your site hours and access windows and we’ll plan around them. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Smaller jobs around Broomer's Corner can be grouped with others nearby. A fixed quote is given before anything starts.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. We agree which rooms close and when, so users always have somewhere to go.
  3. The failed silicone is stripped and every face scraped clean of residue.
  4. Joints are cleaned, degreased and dried before sealing.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. Each room is handed back once the sealant has had its cure time.

Preparing the site

  • Have the specification and drawings to hand
  • Arrange parking or a loading space
  • Send asbestos survey details if the building is pre-2000

Getting a fixed quote

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, call 01277 525 020 or send details through our quote form.

Common questions from Broomer's Corner clients

What documents will you need to give us for a job in Broomer's Corner?

Whatever your site asks for, from RAMS to CSCS details, is confirmed when we quote. We hold £5m public liability insurance, are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded.

Must every washroom in our Broomer's Corner building shut while you work?

Not all at once. We take one block of facilities at a time. We will tell you the curing time for the product before we start.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, tell us and we will confirm them with the quote.

Do you cover Broomer's Corner?

Yes. Broomer's Corner falls within our area, and you can call 01277 525 020 or email drawings and photos to get started.

Do you offer coloured sealant?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.

Will cleaning remove black mould from sealant?

Cleaning may lighten it, but the mould returns. New anti-mould sanitary silicone is the treatment and check the ventilation isn’t the cause.
