Wet areas in Four Ashes’s workplaces

The area within 2 miles of Four Ashes holds a number of hotels. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. Rooms are done in turn so most stay available. Four Ashes is about 29 miles from central London, in a commuter belt where offices and business parks are common. Office toilets in the commuter belt are in use from first arrivals to last departures, so we phase work to keep some facilities open.

For a campus such as Buckinghamshire New University (2 miles south-west of Four Ashes), showers in residences and washrooms in teaching blocks can be programmed around term dates. For an occupier at a site such as Pilot Trading Estate (2 miles south-west of Four Ashes), the canteen and welfare facilities need cleanable joints as much as any office. Customer toilets in retail centres such as Wycombe Retail Park, 2.5 miles south of Four Ashes, rarely close, so resealing is phased.

Four Ashes is about 2 miles north of High Wycombe, in Buckinghamshire. Commercial clients in Four Ashes use us for work on washrooms and wet areas, as part of our coverage of Buckinghamshire.

Washroom sealing for commercial buildings in Four Ashes

Black spotting along a sealant bead is not a cleaning problem. The growth is inside the sealant so it returns whatever the cleaning regime. Only replacement gets rid of it for good. We work on urinals and WCs, accessible toilets and changing rooms and IPS panels and cubicles, and what we are called in for most is mould spotting along silicone joints and sealant lifting along a tray edge. Whoever orders the work in Four Ashes, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Rural businesses near smaller places such as Four Ashes, from cafés to event venues, rely on washrooms and kitchens that stay clean. We plan the work around bookings and opening times.

Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Looking after the joints

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Leave signs up until the cure time is over
  • Clean sealant with gentle products and a soft cloth
  • Photograph and log failed joints across the estate
  • Inspect washroom sealant regularly

Add washroom sealant to routine inspections. Check for mould spots, splits, lifting edges and open joints at trays, basins and urinals and photograph anything new.

Water getting behind IPS panels and vanity units can swell the boards. After that, those parts need replacing rather than resealing.

From enquiry to sign-off

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For work around Four Ashes, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  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. Each joint is cleaned and left dry.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Each area is handed back when ready.

Before we start on site

  • Send any specification or drawings in advance
  • Let us know about inductions and permits
  • Tell us your opening times and when work is allowed

Request a quote

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

When something else is needed

Not every problem is a sealant problem, and we are upfront when that’s the case. It won’t fix:

  • Panel boards already damaged by water
  • Condensation from failed extract fans
  • Water from plumbing, not from a joint

If in doubt, phone 01277 525 020 or email drawings and photos and we’ll say what we think before you book.

Joints and surfaces we work on

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

Why act early in Four Ashes

Sealing on top of old silicone saves nothing. It doesn’t bond, so it peels and traps dirt behind it. Full removal and proper cleaning is what makes the new joint last. Halls, stores and units around places like Four Ashes may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

FAQs: Four Ashes

Must a hotel around Four Ashes close while you work?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. Tell us your quiet periods and access windows and we will plan around them.

Is a hospital such as Wycombe General Hospital somewhere you can work?

Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Does weather matter for sealant work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Can you send site paperwork?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

How much does the work cost?

We don’t publish prices, because every site is different. With photographs or drawings, we can give you a fixed quote.

When can showers be used after new sealant?

Cure times vary by product and temperature. You will get a reopening time for each area before we leave it.

Can you clean the mould off instead of resealing?

Surface cleaning won’t reach mould that has rooted into the bead. New anti-mould sanitary silicone is the treatment and point out if ventilation is part of the problem.
