Common questions from Sullom clients

Which documents can you supply for work in Sullom?

Whatever your site asks for, from RAMS to CSCS details, is confirmed when we quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.

Is Sullom inside the area you cover, given it’s on an island?

Yes, Sullom is within the area we cover. We cover the whole of Scotland. We plan island jobs around the ferry and the forecast, and bring everything the job needs on the first crossing.

Who decides which product is used?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Do you have public liability insurance?

Yes. Our insurance certificate can be sent alongside the quote.

Do you need to remove the old sealant?

The failed bead is always removed. Fresh silicone can’t key to an old bead, so sealing over it soon peels.

Can washrooms stay open while you work?

Only the area we’re working in is closed. Rooms go back into use once the sealant has cured and we start the next.

When is resealing likely to be due?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Washroom sealing for commercial buildings in Sullom

In healthcare and care settings, sealing is part of keeping surfaces cleanable. We work to your organisation’s estates and infection-control requirements and any site permits. Tell us what records you need and we will confirm with the quote. We work on showers, trays and wet room floors, IPS panels and cubicles and vanity units and basins, and the usual reasons a site gets in touch are mould spotting along silicone joints and users noticing mouldy joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Sullom, preparation and product choice get the time they need.

For washroom work around Sullom, we plan so every room on the list is done in one trip where possible. Photos of each washroom and a count of rooms help us quote and plan.

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 spell out the cover before we begin.

Toilets, showers and kitchens around Sullom

Sullom lies within about 1 mile of the sea, and seaside hospitality typically has a peak season that works washrooms hard. Showers and en suites in constant use are where silicone moulds and splits first, which is why off-season resealing makes sense. Work on Sullom has to fit the ferry timetable and the forecast. Knowing how many washrooms there are lets us plan the days on the island.

Washrooms near Sullom get the old silicone stripped out and a fresh anti-mould bead on dry joints.

Sullom is in the Shetland Islands. Businesses, contractors and managing agents in Sullom can call on us for washrooms and wet areas, as part of our coverage of the Shetland Islands. Sullom is one of 63 places we cover in the Shetland Islands.

Commercial sites across ZE2 are covered. If your building is just outside Sullom, we cover Scatsta (2 miles east), Brae (3 miles south), Hogaland (4 miles north), Urafirth (5 miles north-west) and Hillswick (5 miles north-west). Where a site is remote or on an island, we plan travel and materials carefully.

For managing agents and facilities managers

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

Looking after the joints

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Don’t leave trays and floors sitting wet
  • Mention any site permits or estates rules at quote stage
  • Add sealant joints to planned maintenance checks
  • Respect the cure time before reopening each room

If a joint we sealed fails within 12 months, tell us and we will look at it. After that, a routine look catches failing joints early.

A few failed joints can be resealed with hardly any disruption. Left, it tends to become a building-wide job and more closures to manage.

Signs you need washroom sealing in Sullom

A lot of failed washroom sealant was laid over an old bead or a dirty surface. New silicone won’t grip the old so it peels away quickly.

What tends to prompt an enquiry:

  • Sealant lifting along a tray edge
  • Gaps where vanity tops meet the wall
  • Complaints from staff, guests or users about tired washrooms
  • Open joints at the base of cubicle panels

Around Sullom, we keep some washrooms open while others are resealed.

What to look for in a quote

  • The named product and why it was chosen
  • Do they follow the manufacturer’s priming guidance?
  • Will RAMS and insurance details be available?
  • Can the work be phased to keep areas open?

Choosing a commercial sealant contractor

Our process

Before we leave any area, we remove the tape, clean down and inspect every joint. Where the sealant needs time to cure before use, we tell you and sign the area. For a building near Sullom, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.

  1. We agree which washrooms close and when.
  2. Anything behind the joints that needs another trade is flagged.
  3. Old sealant is stripped and the faces prepared.
  4. We reseal with the grade suited to each area.
  5. We confirm reopening times for each washroom.

What we need from you

  • Send asbestos survey details if the building is pre-2000
  • Send your site hours and access windows
  • Confirm the product named in the specification

Getting a fixed quote

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

What happens if it’s left?

A tired washroom says a lot about how a building is run. Visitors notice black sealant even when the room is otherwise spotless. Fresh sanitary silicone lifts a room with very little disruption. Around smaller places like Sullom, halls, stores and seasonal buildings may not be checked often, giving water time to get in. Resealing early avoids that.

The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote when you are ready.

When to bring in a specialist

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
