Common questions from Phantassie clients

Is a smaller place like Phantassie outside your area?

No. Places such as Phantassie are covered as much as the big towns. We cover the whole of Scotland. We plan jobs in smaller places so return trips are kept to a minimum.

Do hotels near Phantassie have to close for sealant work?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. The plan is built around your bookings.

Do you need to see the site first?

Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we will arrange a visit.

Do you use special sealant for toilets and showers?

Each area gets the grade that suits it. Washrooms and showers take anti-mould sanitary silicone, and food areas take a hygienic, food-safe sealant where food contact is possible.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

Do your applicators hold CSCS cards?

Yes. If you need card details for site access, tell us and we will confirm them with the quote.

Do you take on small jobs?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

Washroom sealing for commercial buildings in Phantassie

In a busy washroom, the sealant usually gives up long before the tiles or fittings. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day and mould that roots into it can’t be cleaned away. We strip it out and lay new anti-mould sanitary silicone. We work on IPS panels and cubicles, urinals and WCs and accessible toilets and changing rooms, and what we are called in for most is black mould inside silicone joints that cleaning can’t shift and failed sealant behind washroom basins. A single leaking joint is often how a building in Phantassie first comes to us: we look at the rest while we are there and tell you what we find.

In smaller Scottish places like Phantassie, commercial washrooms are typically in hotels, pubs, schools, care homes and community halls. Mould grows into sealant in any wet room that doesn’t dry out, and the answer is removal and a fresh bead of anti-mould silicone.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Common problems we fix in Phantassie

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

Site and facilities staff are often the first to spot these:

  • Urinal joints that look unhygienic
  • A new bead over an old one coming away
  • Stained or open joints at kitchen sinks and worktops
  • Washrooms that look worn because of the sealant

At a hospital like Belhaven Hospital, which lies east of Phantassie, patient and staff washrooms are best done in short phases agreed with the ward.

Questions to ask before you book

  • Can the work be phased to keep areas open?
  • Is the sealant right for the movement and the substrate?
  • Whether primer will be used where the manufacturer specifies it
  • What the guarantee covers, and for how long

Washroom sealing around Phantassie: how the place shapes the job

With the shore within about 3 miles, Phantassie counts as a coastal location, and coastal hotels, guest houses and holiday sites tend to fill up in the busy months. Showers and en suites in constant use are where silicone moulds and splits first, which is why off-season resealing makes sense. A 2-mile radius around Phantassie takes in a number of hotels. Hotel en suites take daily use, and tired silicone at trays and basins is one of the first things guests notice. We work a handful of rooms at a time, so the hotel keeps letting the rest.

Halls linked to places like Prestonkirk Parish Church host groups all week, which is hard on kitchen and toilet sealant. On an industrial estate such as Gilmerton Industrial Estate (2.9 miles west of Phantassie), staff toilets, showers and canteens are where sanitary sealant takes the most wear.

Phantassie is about 5 miles west of Dunbar, in East Lothian. Commercial clients in Phantassie use us for work on washrooms and wet areas. Phantassie is one of 48 places we cover in East Lothian for washrooms and wet areas. Edinburgh is covered too, some 22 miles away.

On site: what to expect

We bring the products specified for the job, along with primers and backing rod. 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. Jobs near Phantassie are often grouped with others in the same area. Tell us how flexible your dates are.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. The phasing is agreed so there are always facilities open.
  3. The failed silicone is stripped and every face scraped clean of residue.
  4. We clean and dry every surface so the new sealant can grip.
  5. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. You get a reopening time for every room, with signage left up until then.

Before we start on site

  • Make sure the joints can be reached
  • Let us know about inductions and permits
  • For older buildings, check the asbestos register before work

Related advice

When it isn’t the sealant

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Condensation from failed extract fans
  • Failed tanking beneath a wet-room floor or behind tiles
  • Vanity carcasses that have swollen

If in doubt, speak to us on 01277 525 020 or email the details over and we’ll say what we think.

Where we work in Phantassie

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

Should maintenance staff do it?

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.

For managing agents and facilities managers

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

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

Looking after the joints

Keep the joints in good shape with a few simple steps:

  • Add sealant joints to planned maintenance checks
  • Tell us about infection-control or permit rules before we quote
  • Make sure washroom ventilation is running
  • Don’t leave an open joint at a basin or tray

We hand each area back once the silicone has had the cure time the product needs. We’ll tell you when the wet areas can be used, and it helps if signs stay up until then.

Inspectors look at whether kitchen surfaces can be kept clean. Failed sealant around sinks and worktops is easy to put right in good time.
