Looking after the joints

Keep the joints in good shape with a few simple steps:

  • Report split joints at trays and basins early
  • Make sure washroom ventilation is running
  • Clear standing water from shower floors where possible
  • Add sealant joints to planned maintenance checks

Squeegeeing showers and trays after heavy use helps. Standing water on a joint all day shortens its life.

Boards behind panels and vanity tops can swell when water gets past a failed joint. After that, those parts need replacing rather than resealing.

Diagnose, treat, sign off

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. Smaller jobs around Chiddingstone Causeway can be grouped with others nearby. You will have a fixed quote before work starts.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. A phasing plan keeps part of the building’s facilities in use at all times.
  3. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  5. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. Each room is handed back once the sealant has had its cure time.

What we need from you

  • Move anything stored against the joints
  • Arrange parking or a loading space
  • Send asbestos survey details if the building is pre-2000

Do you need washroom sealing in Chiddingstone Causeway?

Warmth, moisture and soap residue are exactly what mould needs, and silicone joints hold onto all three. Anti-mould additives help, but in a poorly ventilated room mould can still take hold eventually.

Look out for the following:

  • Split or peeling sealant at shower trays
  • Discoloured joints around urinals and WC pans
  • Mould spotting along silicone joints
  • Kitchen worktop joints that can’t be kept clean

For a site such as Tonbridge Cottage Hospital, 4.7 miles east of Chiddingstone Causeway, sanitary joints in clinical areas need sound, cleanable sealant and a careful method.

Before you book anyone

  • How the existing material will be dealt with
  • Proof of insurance
  • Their pre-qualification and accreditations
  • Do they follow the manufacturer’s priming guidance?

Central London is about 24 miles from Chiddingstone Causeway. Business park offices have washrooms in daily use by staff, and resealing in phases keeps facilities available.

When it isn’t the sealant

Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:

  • Panel boards already damaged by water
  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • Fittings that move too much to hold a bead

If you are not sure, just call the office on 01277 525 020 or use the quote form and we’ll give you a straight answer before you book.

Joints and surfaces we work on

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

Common questions from Chiddingstone Causeway clients

Could you schedule work at a campus like University of Kent - Tonbridge for the vacation?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Is hospital work, at somewhere like Tonbridge Cottage Hospital, something you do?

Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.

Is Chiddingstone Causeway in your area?

Yes. We cover Chiddingstone Causeway and the rest of Kent, within our coverage of Greater London, South East England and Scotland. For a quote, phone 01277 525 020 or email a schedule or drawings.

What if there’s asbestos in the old mastic?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

How long does a typical visit take?

We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.

How do you choose the sealant?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Is it possible to just clean mouldy silicone?

Not for long. The mould is inside the silicone, so it comes back however often it’s cleaned. Replacement is the lasting fix.

Leave it or put it right?

A tired washroom says a lot about how a building is run. Visitors notice black sealant even when the room is otherwise spotless. Fresh sanitary silicone lifts a room with very little disruption. Older rural buildings around Chiddingstone Causeway 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. For a fixed figure, call for a quote.
