Site staff or a sealant specialist?

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Wet areas in Barkingside’s workplaces

A 2-mile radius around Barkingside takes in plenty of hotels. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. The 2 miles around Barkingside include two care or nursing homes. In care settings, wet rooms, assisted bathrooms and en suites rely on clean, sound sealant. Work is agreed with the manager, around residents’ routines.

Where you are responsible for a hall attached to a building such as Children's Church And Lych Gate At Barnardo's, its kitchen and toilets need sealant that stays cleanable. At a hospital like King George Hospital, 1.2 miles east of Barkingside, patient and staff washrooms are best done in short phases agreed with the ward. At a college such as New City College, which lies south-west of Barkingside, washroom and kitchen sealant is best renewed in the holidays or in phases during term.

How the quote is worked out

Before we quote, we look at:

  • Quantities, in metres or numbers
  • Any access equipment needed
  • Travel to remote or island sites
  • Specialist products, such as fire-rated or hygienic sealants

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

What we need to price the job

Diagnosis starts before we arrive. Let us know:

  • Your programme or deadline
  • Access details, including height
  • Photos of the joints, close up and from further back
  • Asbestos survey details if the building is older

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

Different surfaces, different methods

IPS and cubicle panels

Panels flex slightly in use, so the sealant has to take that movement. Loose panels are flagged before any sealant goes on.

Basins and vanity tops

Natural stone tops can be marked by acetoxy silicone, so the product is chosen to suit.

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 before the next one starts. In Barkingside, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  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. We clean and dry every surface so the new sealant can grip.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. You get a reopening time for every room, with signage left up until then.

Preparing the site

  • Tell us what induction or permit system the site runs
  • Send any specification or drawings in advance
  • Tell us your opening times and when work is allowed

Related advice

Aftercare for building managers

After handover, a little attention goes a long way:

  • Brief cleaning staff to treat joints gently
  • Don’t leave an open joint at a basin or tray
  • Share your site rules when you send details
  • Don’t leave trays and floors sitting wet

Ask your cleaning team to use gentle products and soft cloths on sealant. Aggressive descalers, solvents and scouring pads shorten its life over time.

In food areas, cleanability is something environmental health officers look at. Failed sealant around sinks and worktops is easy to put right in good time.

Honest limits

Sealant solves a lot, but not everything, and we are upfront when that’s the case. These need a different solution:

  • Leaks through tanking or membranes below the finishes
  • Loose panels, vanity units or tiles, which need fixing first
  • A dripping waste or valve behind a panel

Not sure which it is? You can call the office on 01277 525 020 or send details through our quote form and we’ll tell you honestly before you book.

Joints and surfaces we work on

  • IPS panels and cubicles

Your questions answered

Will our hotel in Barkingside need to close for the work?

Rarely, if ever. We take a few rooms out at a time. We agree the order of rooms and the timings with you before we start.

Can you work in a care home near Barkingside with residents in?

Yes. We agree rooms and times with the manager and work a few areas at a time. Tell us about any infection-control or safeguarding requirements and we’ll work to them.

Is it possible to just clean mouldy silicone?

Not for long. The mould is inside the silicone so cleaning only lightens it for a while. Replacement is the lasting fix.

How soon can the area be used again?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

Is old silicone taken out first?

The whole of the old bead is removed and the surfaces cleaned first. That’s what makes the new joint last.

What will the job cost?

Every job gets its own fixed quote. For yours, call 01277 525 020 or email a schedule or drawings.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
