FAQs: Castletown
Is hospital work, at somewhere like Dunbar Hospital, something you do?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is a smaller place like Castletown outside your area?
Not at all. Castletown is within our area. We work across every Scottish council area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
What’s the quickest route to a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.
Can you reseal washrooms in healthcare buildings?
Yes. We work to your estates and infection-control requirements and any site permits. The work is phased around patients or residents.
How long before the toilets can reopen?
Cure times vary by product and temperature. You’ll get a reopening time for each area, and signs stay up until then.
What site paperwork can you supply?
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 CHAS accredited and on Constructionline?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Washroom sealing for commercial buildings in Castletown
In a commercial washroom, sealant is usually the first thing to wear out. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day, and once mould grows into it, it can’t be scrubbed out. We strip it out and lay new anti-mould sanitary silicone. The enquiries we see most involve sealant stained black around basins and showers and gaps where vanity tops meet the wall, across urinals and WCs, kitchens and tea points and vanity units and basins. Looking for mastic applicators who cover Castletown? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Around smaller places such as Castletown, washrooms and kitchens are found in hotels, pubs, schools, care homes and 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.
We stand by our work: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

Different surfaces, different methods
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.
Wet-room floors and floor-to-wall joints
Changing rooms and accessible showers often have wet floors, so their perimeter joints get close attention.

Commercial washrooms in Castletown
With the shore within about 1 mile, Castletown counts as a coastal location, and coastal places often have hotels, guest houses and holiday accommodation with busy seasons. Showers and en suites in constant use are where silicone moulds and splits first, which is why off-season resealing makes sense. Castletown is in the east of Scotland, which is drier than the west. Mould in sanitary sealant comes down to ventilation and use more than the weather outside.
At a hotel such as Castletown Hotel, less than half a mile west of Castletown, the quieter weeks are the time to reseal bathrooms. At a hospital like Dunbar Hospital, 5.5 miles to the west of Castletown, patient and staff washrooms are best done in short phases agreed with the ward.
Castletown is about 5 miles east of Thurso, in Highland. Any commercial site in Castletown is covered. 256 places across Highland fall within our area, Castletown among them.

Site staff or a sealant specialist?
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.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Common problems we fix in Castletown
A lot of failed washroom sealant was laid over an old bead or a dirty surface. Silicone won’t adhere to a silicone bead so it peels away quickly.
If one of these sounds familiar, it’s time for a closer look:
- Kitchen worktop joints that can’t be kept clean
- Shower tray joints that have opened up
- Sealant stained black around basins and showers
- Urinal joints that look unhygienic
Where you’re responsible for a hall attached to a building such as St Trothan's Church, its kitchen and toilets need sealant that stays cleanable.

Why deal with it now?
Gaps and mould in joints give dirt and bacteria somewhere to sit which matters most in healthcare, food and education settings. Sound, smooth joints are much easier to keep clean. For buildings near Castletown, dealing with all the failing joints at once saves return trips. Photos of each area help us quote the whole job.
What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a quote once you have the details.

Keeping the joints sound
Cleaning and maintenance staff play a part too. Pass these on to them:
- Clear standing water from shower floors where possible
- Add sealant joints to planned maintenance checks
- Clean sealant with gentle products and a soft cloth
- Mention any site permits or estates rules at quote stage
Mild cleaning products and non-abrasive cloths look after sanitary silicone best. Strong acids, solvents and scourers wear the surface over time.
Mouldy sealant only gets harder to ignore, and complaints follow. Replacing it early keeps the job to a reseal.
