How we handle washroom sealing in Bowmans

When mould has spotted a silicone joint, more cleaning won’t remove it. The mould has rooted into the silicone itself so it returns whatever the cleaning regime. Replacing the bead is the lasting treatment. Most enquiries involve users noticing mouldy joints and stained sealant around pans and urinals, across IPS panels and cubicles, urinals and WCs and showers, trays and wet room floors. One point of contact handles commercial sealant work in Bowmans from the first photos to the final walk-round, for single jobs and planned programmes alike.

In and around places like Bowmans, hospitality kitchens and toilets see heavy use in busy spells. Sealed joints at sinks, worktops and splashbacks help keep the kitchen cleanable, using a food-safe product near food preparation.

Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Maintenance after handover

Once the work is signed off, these steps help:

  • Keep washrooms out of use until we say the sealant has cured
  • Don’t leave trays and floors sitting wet
  • Keep extract fans working and vents clear
  • Include joints in routine washroom inspections

Include sealant joints in your planned maintenance checks. Look for black spotting, cracks, peeling edges and gaps at the busiest fittings and log what you find.

Inspectors look at whether kitchen surfaces can be kept clean. Failed sealant around sinks and worktops is easy to put right in good time.

Questions about Bowmans

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

In the majority of cases no closure is needed: we work room by room or floor by floor. Housekeeping and our team agree each day’s rooms.

Could you schedule work at a campus like University of Greenwich for the vacation?

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

What guarantee comes with washroom resealing?

A 12-month guarantee covers the work. It covers our workmanship rather than damage, leaks from plumbing or ventilation problems.

How do you choose the sealant?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

How long do sealant joints last?

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

Do you cover Bowmans?

Yes. We cover Bowmans, within our coverage of Greater London, South East England and Scotland. To discuss a job, phone 01277 525 020 or email the details over.

Will cleaning remove black mould from sealant?

Not for long. Mould grows into the sealant itself so cleaning only lightens it for a while. Replacing the bead is the lasting answer.

Our process

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Several jobs near Bowmans can be grouped on one trip. Mention the building’s opening times and we’ll work within 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. We reseal with the grade suited to each area.
  5. We give you a reopening time for every room.

Before we start on site

  • Explain the parking and delivery arrangements
  • Point out any areas we must not close
  • Send any specification or drawings in advance

When it isn’t the sealant

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Loose panels, vanity units or tiles, which need fixing first
  • Water from plumbing, not from a joint
  • Mould caused by poor ventilation, which will return until the extract is fixed

Not sure which it is? You can phone 01277 525 020 or use the quote form and we’ll tell you honestly before you book.

Joints and surfaces we work on

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

Why deal with it now?

Running fresh silicone along a failed bead hides the problem briefly. Silicone won’t grip silicone, so it lifts and holds moisture underneath. Cutting out completely and cleaning back takes a little longer and lasts. In a smaller place such as Bowmans, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.

Different surfaces, different methods

Basins and vanity tops

Water getting past a vanity top joint can swell the board beneath. Prompt resealing keeps the unit sound.

Urinals and WC pans

Floor joints around WC pans are often forgotten. They are checked with everything else.
