Common questions from Greenbank clients
Can you work around term dates at a campus such as Edinburgh Napier University - Merchiston Campus?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Must a hotel around Greenbank close while you work?
Almost never. The work is phased so most rooms stay available. We agree the order of rooms and the timings with you before we start.
How do you choose the sealant?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Can the sealant be colour-matched?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.
Will all the toilets be closed at once?
Just the room being resealed is out of use. Rooms go back into use once the sealant has cured and we start the next.
Can weather delay the job?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Do you use special sealant for toilets and showers?
Each area gets the grade that suits it. Most washroom joints take sanitary silicone while kitchens may need a food-safe grade.
Washroom sealing for commercial buildings in Greenbank
Not every silicone belongs in a washroom. Sanitary silicone contains additives that resist mould, and neutral-cure versions avoid the damage acetoxy types can do to some metals, stone and mirror backings. In food areas, hygienic or food-safe sealants are used where food contact is possible. We work on vanity units and basins, showers, trays and wet room floors and kitchens and tea points, and what we’re called in for most is a new bead over an old one coming away and black mould inside silicone joints that cleaning can’t shift. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Greenbank, preparation and product choice get the time they need.
Shops and offices at the foot of tenement blocks in Scottish cities often have compact staff washrooms and tea points. Small rooms that don’t dry out are where mould gets into sealant first.
The 12-month guarantee is for workmanship rather than 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.

Different surfaces, different methods
Showers and trays
In staff, hotel and changing-room showers, the tray joint and wall corners take the hardest use. Each bead is stripped, the joint dried and new sealant laid.
Basins and vanity tops
A failed joint along a vanity unit lets water into the carcass. Resealing early protects the unit.
Leave it or put it right?
Bleaching black sealant may lighten it for a few days, but the mould is rooted in the silicone and comes back. Replacement deals with the cause in the joint and cleaners stop fighting a losing battle. Scottish city buildings take plenty of rain, and failed external joints let it into stone walls and around frames. Resealing promptly protects the stone and the interior.
A quote for washrooms and wet areas depends on how many there are, their condition and the access. Ask us for a fixed quote.

Work for main contractors and building owners
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.
CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.
Looking after the joints
Cleaning and maintenance staff play a part too. Share these points with them:
- Squeegee showers and trays after busy periods
- Photograph and log failed joints across the estate
- Report split joints at trays and basins early
- Avoid scourers and harsh descalers on silicone
Keep extract fans working and vents clear. A room that stays damp will grow mould on almost anything so report fans that aren’t working to your building services team.
Leaks through tray and wet-floor joints can go unseen until a ceiling marks below. By then, other trades may be needed as well so failed joints are worth acting on quickly.
On site: what to expect
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then handed back before we move to the next. For premises in Greenbank, tell us about access times, shared entrances and any building rules, so the work can be phased and areas kept in use.
- Every room is surveyed and the failed joints listed.
- You get a fixed quote with the phasing plan.
- The whole of the old bead is removed.
- Joints are degreased and dried.

- Tell us your opening times and when work is allowed

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

General trades versus a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
Washroom sealing around Greenbank: what changes locally
The east of Scotland, where Greenbank is, gets less rain than the west. Drier weather outside doesn’t help a washroom with poor extraction, where mould gets into silicone fast. There are plenty of hotels within about 2 miles of Greenbank. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time.
Halls of residence and teaching buildings at universities such as Edinburgh Napier University - Merchiston Campus, 1.2 miles north of Greenbank, are easiest to reseal during vacations. Welfare facilities in units on estates such as West Gorgie Park Industrial Estate, 1.4 miles to the north-west of Greenbank, have showers, toilets and kitchens with sealant that works hard. At a hospital like Royal Edinburgh Hospital, 0.8 miles north of Greenbank, patient and staff washrooms are best done in short phases agreed with the ward.
Greenbank is about 2 miles south of Edinburgh, in Edinburgh. Anywhere in EH10, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 174 places in Edinburgh, large and small.
