Washroom sealing for Wanborough sites

Washroom sealing for commercial buildings in Wanborough

We reseal washrooms and wet areas in offices, hotels, schools, universities, gyms, healthcare buildings and care homes, along with staff kitchens and tea points. The products and the method are chosen for how heavily each space is used. The enquiries we see most involve sealant laid over old silicone and now peeling and discoloured joints around urinals and WC pans, on vanity units and basins, urinals and WCs and showers, trays and wet room floors. Most enquiries from Wanborough 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.

Community buildings around smaller places like Wanborough have kitchens and toilets used by many people. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.

Work we carry out in Surrey comes with a 12-month guarantee. If an installation problem shows up, give us a call on 01277 525 020 or email the details over and we will arrange a return visit.

Questions about Wanborough

Can you work around term dates at a campus such as University of Surrey - Manor Park Campus?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Can you work on a hospital site such as Royal Surrey County Hospital?

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

Do you take on multi-site work?

Yes. Several buildings can share a single quote, and you deal with one contact throughout.

Does weather matter for sealant work?

Outside, 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. Internal work is rarely affected.

Do you work in Wanborough?

Yes. We cover Wanborough and the rest of Surrey, within our coverage of Greater London, South East England and Scotland. For a quote, call the office on 01277 525 020 or email the details over.

Is colour matching possible?

It depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

How much does the work cost?

We don’t publish prices, as every site differs. Send photos or drawings and we’ll price it at a fixed figure.

What we’re called out for in Wanborough

Much of the failed sealant we remove was applied over old silicone or residue. Silicone won’t adhere to a silicone bead, so it soon lets go.

Most enquiries start with one or more of the following:

  • Open joints at the base of cubicle panels
  • Sealant stained black around basins and showers
  • Sealant laid over old silicone and now peeling
  • Urinal joints that look unhygienic

Pupil toilets at schools like Puttenham CofE Infant School take heavy daily use, and the holidays give the window to reseal.

Comparing quotes

  • Are they CHAS accredited or on Constructionline?
  • Will failed sealant be removed rather than covered?
  • Which product they’ll use, and why it suits the joint
  • The terms of the workmanship guarantee

Our contractor checklist

Building owners, agents and FMs in Wanborough

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

On site: what to expect

Working in a building that stays open takes some planning. We sign and contain the area we’re in, keep walkways clear and work section by section so the rest of the building stays in use. If others near Wanborough need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  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. Rooms reopen after the cure time.

What we need from you

  • Clear stock, furniture or equipment away from the joints

  • Send any specification or drawings in advance

Advice

Different surfaces, different methods

Changing rooms and gyms

Changing rooms can be phased so one stays open. Phasing follows your site hours and access windows.

Healthcare and care settings

Accessible and assisted washrooms are used and cleaned intensively so their sealant tends to fail sooner.

When something else is needed

Honesty saves time and money. New sealant won’t cure:

  • Condensation from failed extract fans
  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • Leaks through tanking or membranes below the finishes

Not sure which it is? You can give us a call on 01277 525 020 or send photos by email and we’ll tell you honestly before you book.

What we seal

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

Leave it or put it right?

Running fresh silicone along a failed bead hides the problem briefly. It doesn’t bond, so it peels and traps dirt behind it. Cutting out completely and cleaning back takes a little longer and lasts. Converted and older buildings near places like Wanborough tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

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.

What you get with us

  • Colours confirmed for the specified product
  • Health and safety: CHAS accredited
  • Matching to RAL references, product permitting
  • Work carried out by CSCS-carded applicators

Wet areas in Wanborough’s workplaces

Wanborough lies roughly 31 miles out from central London. Business park offices have washrooms in daily use by staff, so we phase work to keep some facilities open.

Healthcare estates like Royal Surrey County Hospital (to the east of Wanborough) expect contractors to follow their permits and cleaning rules in every washroom. Church halls and community buildings, such as those at Church of St Bartholomew, have kitchens and toilets used by many groups, and their sanitary sealant works hard.
