How we handle washroom sealing in Goose Hill

Black spotting along a sealant bead is not a cleaning problem. The growth is inside the sealant, which is why it comes back however often it is treated. Replacing the bead is the lasting treatment. We work on urinals and WCs, vanity units and basins and IPS panels and cubicles, and the failures we are asked to look at most are black mould inside silicone joints that cleaning can’t shift and washrooms that look worn because of the sealant. Whoever orders the work in Goose Hill, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

Halls and community buildings near places like Goose Hill are used by different groups through the week, and their toilets and kitchens show it. Resealing sinks, worktops and WCs with anti-mould silicone keeps them clean and watertight.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Honest limits

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Panel boards already damaged by water
  • A dripping waste or valve behind a panel
  • A room that stays damp because ventilation isn’t working

Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.

Goose Hill: questions and answers

Do we have to close all our washrooms in Goose Hill for resealing?

Rarely all at once: work is phased so some facilities are always available. We will tell you the curing time for the product before we start.

Is hospital work, at somewhere like West Berkshire Community Hospital, something you do?

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

Is there a guarantee on the work?

Our workmanship has a 12-month guarantee backed by public liability insurance.

What about RAMS and site documents?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

Is it OK to put new silicone on top of the old?

The whole of the old bead is removed and the surfaces cleaned before resealing. That’s what makes the new joint last.

Who decides which product is used?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Can you work to our specification?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

Cost factors for washrooms and wet areas

The price varies from site to site. Expect it to depend on:

  • The site’s rules and procedures
  • Specialist products, such as fire-rated or hygienic sealants
  • Any access equipment needed
  • Whether the work must be split into stages

The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Details that help us quote

It doesn’t need to be a full survey. These details are enough to start:

  • Approximate linear metres or a joint schedule
  • Photos of the joints, close up and from further back
  • When you need the work done
  • The postcode of the building

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, call 01277 525 020 or send details through our quote form.

Maintenance after handover

Keep the joints in good shape with a few simple steps:

  • Don’t leave trays and floors sitting wet
  • Act on the first split you see at a shower tray
  • Brief cleaning staff to treat joints gently
  • Add sealant joints to planned maintenance checks

Keep extract fans working and vents clear. Constant damp lets mould take hold even on anti-mould grades so report fans that aren’t working to your building services team.

In food areas, cleanability is something environmental health officers look at. Resealing sinks, worktops and splashbacks before an inspection is a simple step.

Common problems we fix in Goose Hill

Low-level joints get hit by mop buckets, cleaning trolleys and feet, especially at floor edges and around urinals and WC pans.

It’s worth sending us details if you spot any of the following:

  • Mould spotting along silicone joints
  • A new bead over an old one coming away
  • Urinal joints that look unhygienic
  • Complaints from staff, guests or users about tired washrooms

Schools such as Ashford Hill Primary School have toilets, changing rooms and kitchens that are best resealed in the holidays.

What your quote should include

  • What level of public liability insurance do they hold?
  • Can the work be phased to keep areas open?
  • Is the sealant right for the movement and the substrate?
  • How joint depth will be controlled

Choosing a commercial sealant contractor

Diagnose, treat, sign off

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself typically taking half a day to a day per washroom, depending on the number of fittings. For a building around Goose Hill, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. We agree which rooms close and when, so users always have somewhere to go.
  3. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. We clean and dry every surface so the new sealant can grip.
  5. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. Rooms reopen after the product’s cure time, and we move to the next.

Getting the site ready

  • Send asbestos survey details if the building is pre-2000
  • Move anything stored against the joints
  • Tell us your opening times and when work is allowed

Different surfaces, different methods

Wet-room floors and floor-to-wall joints

Wet-room floors and the joints where flooring turns up the wall need to stay sound. We reseal the floor-to-wall junctions and around drains where sealant is used.

Healthcare and care settings

Clinics, hospitals and care homes need joints that can be kept clean. We work to your estates and infection-control requirements as well as site permits.
