Keeping Offington washrooms open while we work

Offington lies within about 2 miles of the sea, and coastal places often have hotels, guest houses and holiday accommodation with busy seasons. Washrooms used guest after guest wear their sanitary silicone faster, and the quieter months are the natural time to reseal. A 2-mile radius around Offington takes in a good number of hotels. Hotel en suites take daily use, and tired silicone at trays and basins is one of the first things guests notice. Rooms are done in turn so most stay available.

For a hotel such as The Railway Hotel, 1.2 miles to the south-east of Offington, resealing en suites a few rooms at a time keeps the rest available. Toilets at colleges like Worthing College, under half a mile east of Offington, take heavy use from students and staff alike.

Washroom sealing for commercial buildings in Offington

Facilities managers, contractors and building owners have used us for washroom sealing for over 20 years. We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. We are fully insured. Every resealed washroom carries our 12-month guarantee. We work on kitchens and tea points, urinals and WCs and showers, trays and wet room floors, and what we’re called in for most is stained or open joints at kitchen sinks and worktops and sealant lifting along a tray edge. Most enquiries from Offington start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Rural businesses near smaller places such as Offington, from cafés to event venues, rely on washrooms and kitchens that stay clean. Tell us your opening times and quiet periods and we’ll plan around them.

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.

Leave it or put it right?

Cleaning mouldy sealant only masks it but the growth is inside the bead and returns. A full reseal deals with it and your cleaning team stops chasing it. Older rural buildings around Offington move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.

Why us?

  • Colours confirmed for the specified product
  • Workmanship guaranteed for 12 months
  • CHAS accredited
  • CSCS-carded applicators

On site: what to expect

Occupied buildings need a little choreography. 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. For work around Offington, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right 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. 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. Rooms reopen after the product’s cure time, and we move to the next.

Before we start on site

  • Flag any permit to work we will need
  • Send asbestos survey details if the building is pre-2000
  • Tell staff and tenants when we’ll be in

When to bring in a specialist

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

When to call us in Offington

Washrooms are warm, damp and full of organic residue, and silicone joints hold onto all three. Anti-mould additives help, but in a poorly ventilated room mould can still take hold eventually.

Most enquiries start with something like this:

  • Discoloured joints around urinals and WC pans
  • Sealant laid over old silicone and now peeling
  • Stained or open joints at kitchen sinks and worktops
  • Complaints from staff, guests or users about tired washrooms

For buildings on a site such as Downlands Business Park, 1.1 miles east of Offington, washrooms and tea points can be resealed in phases through the working week.

Questions to ask before you book

  • The terms of the workmanship guarantee
  • Are they CHAS accredited or on Constructionline?
  • Whether old or failed sealant will be cut out, not overlaid
  • Will RAMS and insurance details be available?

Questions to ask before you appoint anyone

What we can’t put right

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

  • Leaks through tanking or membranes below the finishes
  • Vanity carcasses that have swollen
  • Water from plumbing, not from a joint

If in doubt, give us a call on 01277 525 020 or email us and we will say what we think before you book.

Joints and surfaces we work on

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

Questions about Offington

Can you work on a hospital site such as Worthing Hospital?

Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.

Will you plan work around the academic year at somewhere like Worthing College?

Yes, holiday working periods are the norm on campus jobs. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Can weather delay the job?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

Is it possible to just clean mouldy silicone?

Surface cleaning won’t reach mould that has rooted into the bead. We replace the sealant with an anti-mould sanitary grade and check the ventilation isn’t the cause.

Which silicone is right for commercial washrooms?

It depends on the joint. Most washroom joints take sanitary silicone while kitchens may need a food-safe grade.

Will all the toilets be closed at once?

We phase it so there are always facilities open. One washroom, one bank of cubicles or one changing room is done at a time. Tell us your site hours and access windows and we will plan around them.

Can you handle several sites?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

Cost factors for washrooms and wet areas

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

  • Access and working height
  • Quantities, in metres or numbers
  • Phasing around occupants
  • Which sealant the job calls for

Pricing washrooms and wet areas depends on quantities, condition and access. Ask us for a fixed quote.

Sending details for a quote

Diagnosis starts before we arrive. Tell us:

  • Whether the building will be occupied during the work
  • Approximate linear metres or a joint schedule
  • The site address and postcode
  • How the joints are reached, and at what height

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, ring 01277 525 020 or email us.
