Washroom sealing in Stanton Harcourt

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Washroom sealing in Stanton Harcourt, done properly

Black spotting along a sealant bead is not a cleaning problem. The mould has rooted into the silicone itself, which is why it comes back however often it is treated. Only replacement gets rid of it for good. We work on vanity units and basins, kitchens and tea points and accessible toilets and changing rooms, and the usual reasons a site gets in touch are washrooms that look worn because of the sealant and open joints along basins and vanity units. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Stanton Harcourt is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Smaller places such as Stanton Harcourt still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

On site: what to expect

Occupied buildings need a little choreography. We sign and contain the area we are in, keep walkways clear and move on in phases so staff and visitors can carry on around us. For work around Stanton Harcourt, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. Every room is surveyed and the failed joints listed.
  2. The fixed quote sets out the rooms, the products and the phasing.
  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. Rooms reopen after the cure time.

What we need from you

  • Share your working hours and any access restrictions
  • Let building users know which areas are affected
  • Make sure the joints can be reached

Related advice

Your questions answered

Can you work around term dates at a campus such as Azad University in Oxford?

Yes. We plan campus work around teaching, exams and residence turnarounds. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Will the toilets in our Stanton Harcourt building be out of use?

Usually 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.

Can you quote from photographs?

Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.

How long does a job like this take?

That varies with the scale of the job, but the work typically takes a morning or so for a small washroom, longer where showers and changing rooms are included. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

What do you charge?

It depends on the job: quantities, access, the product and any phasing. Call for a quote and we’ll price it properly.

Do you use special sealant for toilets and showers?

Each area gets the grade that suits it. Washrooms and showers take anti-mould sanitary silicone while kitchens may need a food-safe grade.

Can weather delay the job?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

What sets the cost

The price varies from site to site. It mainly depends on:

  • Quantities, in metres or numbers
  • Travel to remote or island sites
  • Site requirements such as inductions and permits
  • Specialist products, such as fire-rated or hygienic sealants

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Sending details for a quote

A few photographs plus some basic facts will normally do. Please tell us:

  • Any specification or named product
  • Drawings or a marked-up plan, if available
  • When you need the work done
  • The postcode of the building

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, call 01277 525 020 or email the details over.

Site staff or a sealant specialist?

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Owners, agents and contractors

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

What the job involves on each surface

IPS and cubicle panels

Cubicle and IPS panels move when leaned on or knocked, so the sealant has to take that movement. We check fixings before sealing.

Kitchens and tea points

Kitchen joints need to be smooth and sealed so they can be cleaned properly. Where food contact is possible, we use a hygienic, food-safe sealant.

When to call us in Stanton Harcourt

Mop buckets, trolleys and knocks from users damage joints near the floor at skirting lines, urinal bases and around pans.

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

  • Sealant laid over old silicone and now peeling
  • Failed joints along IPS and cubicle panels
  • Split or peeling sealant at shower trays
  • Mould spotting along silicone joints

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

Questions to ask before you book

  • What level of public liability insurance do they hold?
  • Will failed sealant be removed rather than covered?
  • Who will actually carry out the work
  • Which product they’ll use, and why it suits the joint
