Washroom sealing for Crockhurst Street sites

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

Doing it in-house

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Washroom sealing for commercial buildings in Crockhurst Street

Accessible WCs, showers and changing areas have their own pinch points: wet-floor edges, tray perimeters, basin tops and the line where flooring meets the wall. An open joint there lets water track under flooring or behind wall panels so they get particular attention. Site teams most often ask us about failed joints along IPS and cubicle panels and open joints along basins and vanity units, on accessible toilets and changing rooms, showers, trays and wet room floors and IPS panels and cubicles. Most enquiries from Crockhurst Street start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Smaller places such as Crockhurst Street still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Sealant that has gone black with mould normally can’t be cleaned, so it is cut out and replaced.

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.

Different surfaces, different methods

Changing rooms and gyms

We phase work so not every changing area is closed at once. Tell us your site hours and access windows and we’ll plan around them.

IPS and cubicle panels

IPS panels and cubicle systems have joints at the wall, the floor and the worktop. Those joints protect the boards behind from water.

How a job runs

Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Rural sites near Crockhurst Street may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. We agree which rooms close and when, so users always have somewhere to go.
  3. We strip out the old bead and clean off the residue left behind.
  4. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  5. New sanitary silicone with anti-mould additives goes in and is tooled neat.
  6. Each room is handed back once the sealant has had its cure time.

What we need from you

  • Send asbestos survey details if the building is pre-2000
  • Let building users know which areas are affected
  • Point out parking and an unloading spot

Cost factors for washrooms and wet areas

Each job is priced on its own details. The main factors are:

  • Distance, for remote addresses
  • The total length or number of joints
  • Backing rod, priming and other preparation
  • Any access equipment needed

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.

What to include in your enquiry

A few photographs plus some basic facts will normally do. It helps to include:

  • Your programme or deadline
  • The site address and postcode
  • Photos of the joints, close up and from further back
  • Whether the building will be occupied during the work

Leave it or put it right?

Open or mouldy joints are hard to keep hygienic, and in kitchens, clinics and schools that is a real concern. A smooth, sealed joint can be cleaned properly. Older rural buildings around Crockhurst Street move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

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

Crockhurst Street: questions and answers

Can you take on a job at a hospital such as Tonbridge Cottage 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.

Could you schedule work at a campus like University of Kent - Tonbridge for the vacation?

Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

How do you deal with asbestos in old sealant?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

What about RAMS and site documents?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

Is it possible to just clean mouldy silicone?

Surface cleaning won’t reach mould that has rooted into the bead. New anti-mould sanitary silicone is the treatment and check the ventilation isn’t the cause.

Do you work in hospitals, clinics and care homes?

We do. We work to your estates and infection-control requirements and any site permits, and phase the work so areas keep facilities.

Are you CHAS accredited and on Constructionline?

Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
