Washroom sealing in Stubb's Cross

From one staff toilet in Stubb's Cross to washrooms across a whole estate, the route is the same: send details, get a fixed quote, we seal, guaranteed. A few photos and a count of fittings are enough for a quick quote and a site visit is an option. Most enquiries involve kitchen worktop joints that can’t be kept clean and black mould inside silicone joints that cleaning can’t shift, across kitchens and tea points, IPS panels and cubicles and vanity units and basins. A single leaking joint is often how a building in Stubb's Cross 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.

In and around smaller places like Stubb's Cross, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Sealant that has gone black with mould typically can’t be cleaned, so it is cut out and replaced.

A 12-month guarantee applies to all our work in Kent. If an installation problem shows up, call 01277 525 020 or send photos by email and we’ll arrange a return visit.

Cost factors for washrooms and wet areas

A fixed quote reflects the actual work. It allows for:

  • Location, for remote and island sites
  • Quantities, in metres or numbers
  • The product specified
  • Removal of failed or old sealant

What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote when you’re ready.

Sending details for a quote

A good diagnosis starts with the right details. Let us know:

  • The asbestos register, for older buildings
  • A wide shot and a close-up of the area
  • Specification clauses that apply
  • How the joints are reached, and at what height

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

Questions about Stubb's Cross

Is hospital work, at somewhere like William Harvey Hospital, something you do?

Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is Stubb's Cross too small for you to travel to?

No. Small places get the same service as large ones. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.

How long before the toilets can reopen?

That varies with the sealant and the room temperature. Each room gets its own reopening time from us before we leave it.

Will all the toilets be closed at once?

Only the area we are working in is closed. Each room reopens after the sealant’s cure time, then we move on.

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. Replacing the bead is the lasting answer.

Are you insured?

Yes. Our insurance certificate can be sent alongside the quote.

What will the job cost?

Each job is quoted on its own details. For yours, speak to us on 01277 525 020 or email drawings and photos.

Keeping the joints sound

After handover, these steps help:

  • Add sealant joints to planned maintenance checks
  • Clean sealant with gentle products and a soft cloth
  • Squeegee showers and trays after busy periods
  • Act on the first split you see at a shower tray

Ventilation is half the battle. A room that stays damp will grow mould on almost anything so report fans that aren’t working to your building services team.

Mould in a joint spreads along the bead and into nearby grout and users notice. Replacing it early keeps the job to a reseal.

Should maintenance staff do it?

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

How a job runs

Site rules come first: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact. Jobs in and around smaller places like Stubb's Cross are typically planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. Every room is surveyed and the failed joints listed.
  2. You get a fixed quote with the phasing plan.
  3. The whole of the old bead is removed.
  4. Joints are degreased and dried.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Each area is handed back when ready.

What we need from you

  • Send your site hours and access windows
  • Point out parking and an unloading spot
  • Confirm the product named in the specification

Getting a fixed quote

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.

Why deal with it now?

Leaving the job until a shutdown often means living with it for months. Phasing lets it happen now, with facilities kept in use. Converted and older buildings near places like Stubb's Cross tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

There’s no price list, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.

Do you need washroom sealing in Stubb's Cross?

Washrooms are warm, damp and full of organic residue, and silicone joints hold onto all three. Even anti-mould grades can be colonised over time where extraction is poor.

Site and facilities staff are often the first to spot these:

  • Urinal joints that look unhygienic
  • Failed sealant in a tea point or staff kitchen
  • Gaps where vanity tops meet the wall
  • Complaints from staff, guests or users about tired washrooms

Toilets at colleges like Ashford College (to the north-east of Stubb's Cross) take heavy use from students and staff alike.

Comparing quotes

  • Their public liability cover
  • Whether their applicators hold CSCS cards
  • Can the work be phased to keep areas open?
  • Will failed sealant be removed rather than covered?
