Common questions from Craignure clients
Must every washroom in our Craignure building shut while you work?
Not all at once. We take one block of facilities at a time. We will tell you the curing time for the product before we start.
Do you take on work at healthcare sites like Mull and Iona Community Hospital?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
How long does a job like this take?
It depends on the scope, but the work normally takes half a day to a day per washroom, depending on the number of fittings. For bigger or phased jobs, we will set out a timescale with the quote.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
What about RAMS and site documents?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
Which sealant will you use?
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.
About our washroom sealing in Craignure
Accessible toilets, shower rooms and changing rooms have joints that work harder than most: shower trays, wet-room floor edges, basins and floor-to-wall junctions. Gaps in those places let water get under the floor or behind panels, so we look at them closely. We work on accessible toilets and changing rooms, showers, trays and wet room floors and urinals and WCs, and the failures we’re asked to look at most are a new bead over an old one coming away and users noticing mouldy joints. One point of contact handles commercial sealant work in Craignure from the first photos to the final walk-round, whether it’s one building or several.
Hotels and holiday accommodation in rural Scotland have busy and quiet seasons, so washroom work is often best planned for quieter months.
Work we carry out in Argyll and Bute comes with a 12-month guarantee. If an installation problem shows up, call the office on 01277 525 020 or send details through our quote form and we will arrange a return visit.

Honest limits
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:
- Water from plumbing, not from a joint
- Hollow tiles or loose panels behind the joint
- Swollen or delaminated boards behind panels or vanity tops
If you are not sure, just speak to us on 01277 525 020 or send photos by email and we will give you a straight answer.

What else we do in Craignure
Our process
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes between a morning and a week or so, set by the number of rooms and the phasing you need, and our waste is bagged and taken away as we go. For work around Craignure, we aim for one trip, which is why we ask for photographs and a full list first. External joints need a dry spell as well.
- We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
- The phasing is agreed so there are always facilities open.
- Failed silicone is removed completely and the surfaces cleaned of every trace.
- We clean and dry every surface so the new sealant can grip.
- New sanitary silicone with anti-mould additives goes in and is tooled neat.
- You get a reopening time for every room, with signage left up until then.
Getting the site ready
- Confirm the product named in the specification
- Point out parking and an unloading spot
- Move anything stored against the joints

Advice
Keeping the joints sound
For the best life from the joints:
- Keep a record of which washrooms need attention
- Clear standing water from shower floors where possible
- Include joints in routine washroom inspections
- Act on the first split you see at a shower tray
Squeegeeing showers and trays after heavy use helps. Joints that sit wet for hours fail sooner.
Inspectors look at whether kitchen surfaces can be kept clean. Failed sealant around sinks and worktops is easy to put right in good time.
Washroom sealing in Craignure: the local picture
With the shore within about 1 mile, Craignure counts as a coastal location, and coastal places often have hotels, guest houses and holiday accommodation with busy seasons. Heavy seasonal use is hard on shower and basin sealant, so resealing in the quieter months keeps rooms ready. The west of Scotland, where Craignure is, gets more rain than the east. In a damp climate, washrooms that aren’t well ventilated stay wet for longer, and sealant in a room that never dries out moulds faster.
At a hotel such as Isle of Mull Hotel, less than half a mile to the south of Craignure, the quieter weeks are the time to reseal bathrooms. For a hall at a building such as Torosay Church, resealing the kitchen and toilets can be fitted between bookings.

We work on buildings around Craignure Inn and the streets around them. Other landmarks nearby include Duart Castle (2.8 miles south-east) and Mull and Iona Community Hospital (under half a mile north-west).
When to call us in Craignure
Sometimes the sealant fails because something behind it is moving or wet: a loose panel, a leaking waste or water coming through the wall. We look for it before resealing and tell you if another trade is needed.
It’s worth sending us details if you spot any of the following:
- Black mould inside silicone joints that cleaning can’t shift
- Urinal joints that look unhygienic
- Resealing that didn’t last because the old bead stayed
- Panel joints letting water behind
Healthcare estates like Mull and Iona Community Hospital (under half a mile north-west of Craignure) expect contractors to follow their permits and cleaning rules in every washroom.

How the job changes by surface
Showers and trays
If a tray moves too much or is cracked, it needs attention first, and we will say so before resealing.
Kitchens and tea points
Staff kitchens and tea points have joints at worktops, sinks and splashbacks. Sealed joints leave no gaps for food and dirt.
Site staff or a sealant 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.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
