About our washroom sealing in The Willows

In a commercial washroom, sealant is typically the first thing to wear out. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day, and once mould grows into it, it can’t be scrubbed out. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. The enquiries we see most involve resealing that didn’t last because the old bead stayed and failed sealant behind washroom basins, across vanity units and basins, IPS panels and cubicles and showers, trays and wet room floors. A single leaking joint is often how a building in The Willows first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Farm shops, cafés and venues in converted rural buildings around places like The Willows have busy toilets and kitchens. We plan the work around bookings and opening times.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Why it’s worth doing now in The Willows

A tired-looking washroom doesn’t always need a refurbishment. Where tiles, panels and fittings are sound, new sealant may be enough to put it right for now. Around The Willows, it’s better to renew all the failing joints at once. Send photographs of each area and we’ll quote for the lot.

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’ll explain how it’s made up.

FAQs: The Willows

Will all the washrooms in our The Willows building be closed at once?

Typically only some of them, for a short time. We work in phases so other facilities stay open. Each area is handed back once the sealant has cured enough to use.

Is hospital work, at somewhere like Herts and Essex Hospital, something you do?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

Do you take on multi-site work?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

Can weather delay the job?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

Is any job too small?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Do you need to remove the old sealant?

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

Are you insured?

Yes. We are fully insured, including public liability cover.

Clinical washrooms at sites like Herts and Essex Hospital (5.6 miles south-east of The Willows) are scheduled with the ward so the room is out of use for as little time as possible.

On site: what to expect

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes a few hours for one toilet block, with bigger buildings phased across a number of visits, and our waste is bagged and taken away as we go. If others near The Willows need work, visits can be combined. You’ll have a fixed quote before work starts.

  1. Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
  2. A phasing plan keeps part of the building’s facilities in use at all times.
  3. We strip out the old bead and clean off the residue left behind.
  4. Joints are cleaned, degreased and dried before sealing.
  5. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. Rooms reopen after the product’s cure time, and we move to the next.

What we need from you

  • Clear stock, furniture or equipment away from the joints
  • Point out any areas we must not close
  • Warn occupants and staff about the work

Advice

What we are called out for in The Willows

Warmth, moisture and soap residue are exactly what mould needs, and sealant joints trap all three. Even anti-mould grades can be colonised over time where extraction is poor.

Most enquiries start with something like this:

  • Gaps where vanity tops meet the wall
  • Split or peeling sealant at shower trays
  • Stained sealant around pans and urinals
  • Open joints at the base of cubicle panels

Church halls and community buildings, such as those at Church of St Mary, have kitchens and toilets used by many groups, and their sanitary sealant works hard.

Questions to ask before you book

  • What the guarantee covers, and for how long
  • How they handle RAMS and site documents
  • Their plan for phasing and protecting the area
  • Whether their applicators hold CSCS cards

Our contractor checklist

When something else is needed

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Loose panels, vanity units or tiles, which need fixing first
  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • Water escaping beneath the floor rather than through a joint

If you are not sure, just ring 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.
