Questions about An t-Ob

What site paperwork comes with a job in An t-Ob?

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

Must every washroom in our An t-Ob building shut while you work?

Usually only some of them, for a short time. We work in phases so other facilities stay open. Sanitary silicone needs time to cure before the area is used, and we’ll tell you how long for the product used.

How do you choose the sealant?

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.

How soon can a washroom be used after resealing?

Cure times vary by product and temperature. Each room gets its own reopening time from us before we leave it.

What happens if old sealant might contain asbestos?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

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 we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Is old silicone taken out first?

The failed bead is always removed. New silicone won’t stick to the old, so sealing over it soon peels.

How we handle washroom sealing in An t-Ob

We reseal washrooms and wet areas in offices, hotels, schools, universities, gyms, healthcare buildings and care homes, plus the kitchens and tea points that go with them. The products and the method are chosen for how heavily each space is used. Site teams most often ask us about black mould inside silicone joints that cleaning can’t shift and panel joints letting water behind, on IPS panels and cubicles, vanity units and basins and urinals and WCs. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in An t-Ob it comes down to the same thing: the right product in a properly prepared joint.

For washroom work around An t-Ob, we plan so every room on the list is done in one trip where possible. Send photos and a room list and we’ll give a fixed quote.

A 12-month guarantee applies to all our work in Na h-Eileanan Siar. If an installation problem shows up, call the office on 01277 525 020 or email a schedule or drawings and we’ll arrange a return visit.

Owners, agents and contractors

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. An t-Ob can form part of a wider programme.

If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.

What sealant work can’t fix

We check first that sealant really is the fix. It isn’t the answer for:

  • Water escaping beneath the floor rather than through a joint
  • Loose panels, vanity units or tiles, which need fixing first
  • A room that stays damp because ventilation isn’t working

Not sure which it is? You can call 01277 525 020 or send photos by email and we’ll tell you honestly.

Where we work in An t-Ob

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

Leave it or put it right?

A failed joint behind a basin or along a shower tray lets water run where it shouldn’t. That can lead to swollen boards, marked ceilings below and lingering smells, and fixing that takes far more work than resealing. Around smaller places like An t-Ob, halls, stores and seasonal buildings may not be checked often, so a failed joint has time to cause damage. Resealing early avoids that.

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Sanitary sealant for An t-Ob buildings

The sea is no more than about 1 mile from An t-Ob, and seaside hospitality normally has a peak season that works washrooms hard. Bathrooms turned round daily in the busy months need sound, cleanable joints, so resealing in the quieter months keeps rooms ready. The west of Scotland, where An t-Ob is, gets more rain than the east. Where ventilation is poor, damp washrooms here tend to see black mould in the sealant sooner.

Phased work lets washrooms in and around An t-Ob stay partly open while sealant is renewed. Washrooms near An t-Ob get the old silicone stripped out and a fresh anti-mould bead on dry joints.

An t-Ob is in Na h-Eileanan Siar. We cover commercial sites throughout An t-Ob, whether it’s a single job or part of a planned programme. Across Na h-Eileanan Siar, 87 places are covered, including An t-Ob.

We take on washrooms and wet areas across the HS5 postcode area. For a building on Pier Road, Ferry Road and Strond Road or nearby, send details and we will quote for washrooms and wet areas.

General trades versus a specialist

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. For that reason, many FMs and contractors use a sealant specialist from the outset.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

Keeping the joints sound

Problems stay small when the joints are checked regularly. Specifically:

  • Keep washrooms out of use until we say the sealant has cured
  • Act on the first split you see at a shower tray
  • Keep a record of which washrooms need attention
  • Brief cleaning staff to treat joints gently

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.

Mouldy sealant only gets harder to ignore, and complaints follow. Dealing with it while it’s just the sealant keeps it simple.

Diagnose, treat, sign off

At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. Jobs near An t-Ob are often grouped with others in the same area. Let us know if your dates have any give.

  2. You get a fixed quote with the phasing plan.
