Washroom sealing in Eythorne

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

What happens if it’s left?

A failed joint behind a basin or along a shower tray lets water run where it shouldn’t. That can lead to swollen boards, marked ceilings below and lingering smells which costs more to fix than a reseal. One visit to deal with every failing joint makes more sense than several trips to a place like Eythorne. Photos of every joint help us quote for the whole job.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Why clients in Eythorne choose us

  • Commercial sealant work since 2005
  • Failed material removed, not covered up
  • CHAS accredited contractor
  • A Constructionline member, so easy to vet

Washroom sealing in Eythorne, done properly

Facilities managers, contractors and building owners have used us for washroom sealing for over 20 years. We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. There is public liability insurance behind every job. Every resealed washroom carries our 12-month guarantee. We work on showers, trays and wet room floors, vanity units and basins and urinals and WCs, and the failures we’re asked to look at most are a new bead over an old one coming away and urinal joints that look unhygienic. Facilities teams, main contractors and managing agents in Eythorne tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

In and around smaller places like Eythorne, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, speak to us on 01277 525 020 or email the details over and we will come back to it.

Quoting for work in Eythorne

Before we quote, we look at:

  • Whether the work must be split into stages
  • Quantities, in metres or numbers
  • How accessible the joints are
  • The product specified

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

Before you send an enquiry

It doesn’t need to be a full survey. A few details are enough to get going:

  • Approximate linear metres or a joint schedule
  • The asbestos register, for older buildings
  • The postcode of the building
  • Any specification or named product

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to ring 01277 525 020 or send details through our quote form with what you know.

Diagnose, treat, sign off

Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. If others near Eythorne need work, visits can be combined. You will have a fixed quote before work starts.

  1. Every room is surveyed and the failed joints listed.
  2. You get a fixed quote with the phasing plan.
  3. Old sealant is removed completely and the faces cleaned.
  4. Joints are degreased and dried.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Each area is handed back when ready.

What we need from you

  • Share your working hours and any access restrictions
  • Point out any areas we must not close
  • Send any specification or drawings in advance

Getting a fixed quote

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.

Advice

Commercial clients in Eythorne

We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, which keeps the paperwork simple.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

When something else is needed

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

  • A dripping waste or valve behind a panel
  • Leaks through tanking or membranes below the finishes
  • Mould caused by poor ventilation, which will return until the extract is fixed

Not sure which it is? You can call 01277 525 020 or send details through our quote form and we will tell you honestly.

What we seal

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

Questions about Eythorne

Is Eythorne too far out for you?

Not at all. Eythorne is within our area. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.

Can you take on a job at a hospital such as Buckland Hospital?

Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.

Are your applicators CSCS-carded?

Yes. We use CSCS-carded applicators.

Does the weather affect the work?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Will you quote for a small job?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

How long before the toilets can reopen?

Cure times vary by product and temperature. Each room gets its own reopening time from us before we leave it.

Will cleaning remove black mould from sealant?

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

What the job involves on each surface

IPS and cubicle panels

IPS panels and cubicle systems have joints at the wall, the floor and the worktop. They stop water reaching the panel boards.

Wet-room floors and floor-to-wall joints

Wet floors are common in accessible showers and changing rooms so the edges are checked carefully.
