Questions we are asked in Bigton

What paperwork can you provide for a job in Bigton?

RAMS, insurance certificate, CSCS details: list what the site needs and we will confirm it with the quote. We’re CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.

Will you travel to Bigton on the island?

Yes. Islands are part of our area, Bigton included. Ferry times and the weather set the plan, so we ask for photographs and a full list first.

What happens if old sealant might contain asbestos?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

Can the sealant be colour-matched?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.

How soon can a washroom be used after resealing?

That varies with the sealant and the room temperature. You’ll get a reopening time for each area before we leave it.

Are you CHAS accredited and on Constructionline?

Yes. We’re CHAS accredited and a Constructionline member.

Are your applicators CSCS-carded?

Yes. We use CSCS-carded applicators.

Washroom sealing in Bigton

Accessible toilets, shower rooms and changing rooms have joints that work harder than most: wet-floor edges, tray perimeters, basin tops and the line where flooring meets the wall. Gaps in those places let water get under the floor or behind panels so they get particular attention. We work on urinals and WCs, vanity units and basins and accessible toilets and changing rooms, 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. For commercial sealant work in Bigton, you deal with one contact from quote to sign-off, whether it’s one building or several.

Travel to smaller places like Bigton is planned so the work is finished on one visit. Send photos and a room list and we’ll give a fixed quote.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

General trades versus a specialist

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Putting right a botched joint often costs more than sealing it well at the start, 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.

For managing agents and facilities managers

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Bigton can form part of a wider programme across the Shetland Islands.

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so the building keeps working while we do.

Maintenance after handover

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Clean sealant with gentle products and a soft cloth
  • Include joints in routine washroom inspections
  • Photograph and log failed joints across the estate
  • Make sure washroom ventilation is running

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.

Commercial washrooms in Bigton

Bigton sits close to the coast, within about 1 mile, and seaside hospitality usually has a peak season that works washrooms hard. Washrooms used guest after guest wear their sanitary silicone faster, and the quieter months are the natural time to reseal. The east of Scotland, where Bigton is, gets less rain than the west. Mould in sanitary sealant comes down to ventilation and use more than the weather outside.

In any commercial washroom in or near Bigton, mouldy sealant is cut out rather than cleaned, and anti-mould sanitary silicone goes on clean, dry joints.

Bigton is in the Shetland Islands. We cover Bigton and the rest of the Shetland Islands, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Across the Shetland Islands, 63 places are covered, including Bigton.

Work on washrooms and wet areas is covered throughout ZE2, whatever the building. We also cover Levenwick (2 miles east), Hoswick (3 miles north-east), South Scousburgh (3 miles south), Sandwick (3 miles north-east) and Boddam (4 miles south) for washrooms and wet areas. Nearby towns on our patch include Lerwick (13 miles north-east), Sound (13 miles north-east) and Scalloway (11 miles north). Where a site is remote or on an island, travel and materials need planning ahead, so the full address helps from the start.

Cost factors for washrooms and wet areas

Each job is priced on its own details. The things that drive the figure:

  • Travel to remote or island sites
  • The size and state of each joint
  • The site’s rules and procedures
  • Specialist products, such as fire-rated or hygienic sealants

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Details that help us quote

It doesn’t need to be a full survey. A few details are enough to get going:

  • Asbestos survey details if the building is older
  • Any dates the work must fit around
  • Where the site is, with the postcode
  • Access details, including 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 a schedule or drawings.

Diagnose, treat, sign off

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. For work around Bigton, we aim for one trip, which is why we ask for photos and a full list first. Outside work also needs a suitable weather window.

  1. Every room is surveyed and the failed joints listed.
  2. The fixed quote sets out the rooms, the products and the phasing.
  3. The whole of the old bead is removed.
  4. Each joint is cleaned and left dry.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Each area is handed back when ready.

What we need from you

  • Flag any permit to work we will need
  • Explain the parking and delivery arrangements
  • Tell staff and tenants when we’ll be in

Getting a fixed quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photos and a few notes.

Advice

When to call us in Bigton

Much of the failed sealant we remove was applied over old silicone or residue. New silicone won’t grip the old, so it soon lets go.

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

  • Mould spotting along silicone joints
  • Urinal joints that look unhygienic
  • Shower tray joints that have opened up
  • Stained or open joints at kitchen sinks and worktops

Halls linked to places like St Ninian's Church And Gatepiers host groups all week, which is hard on kitchen and toilet sealant.

Before you book anyone

  • How the existing material will be dealt with
  • Their plan for phasing and protecting the area
  • Will CSCS-carded applicators be on site?
