For landlords and businesses

Commercial sealant in Sandbank, done properly
In student and care accommodation, there are often many near-identical bathrooms. We agree a programme and work through them in order, working around residents and staff routines. Typical jobs include mouldy bathrooms flagged at a tenancy check and split sealant around staff kitchen worktops and sinks, on office washrooms & kitchens, hotel bathrooms and retail & leisure sites.
If you look after holiday lets, a guest house or a community building in or near Sandbank, the washrooms and kitchens need the same care as any city building, and fire-rated joints should be kept in good order.
All our work is covered by our one-year guarantee, wherever you are in Argyll and Bute.

Leave it or put it right?
Room by room, the work is quick: it takes a few hours per area, with larger sites planned over several visits. After that, each area needs its cure time before use, so planning the order matters more than the hours on site. In an older home around Sandbank, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

What sealant work can’t fix
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Cracked trays or baths rather than failed joints
- Leaking pipework, valves or wastes (a plumber’s job)
- A broken extractor fan behind the mould problem

Workplaces and buildings in Sandbank
If you run a hotel, guest house or holiday let in a coastal place like Sandbank, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. Private landlords in Scotland must meet the Repairing Standard, so landlords with several properties often need sealant work across them all.
Schools such as Dunoon Grammar School are buildings too, and washroom and kitchen sealant can be programmed around term times or opening hours. If you let a flat or house near Gourock station, we can quote for one property or a whole portfolio of rentals.

How it works
We keep the work tidy and contained to the joints we are treating. Expect the work to take a few hours per area, with larger sites planned over several visits, and we tell you how long to leave it before we go. Somewhere like Sandbank may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We walk the site with you and agree the rooms, the order and the hours.
- Every area is sheeted and the old silicone stripped out.
- Joints are cleaned, treated for mould and dried.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealants elsewhere.
- Rooms are checked and returned with a cure time so staff know when to use them.
Preparing for the visit
- Move anything stored near the joints
- Mention any sign-in or site rules at work premises
- For indoor joints, keep the area dry beforehand if you can

What affects the quote in Sandbank
Call for a quick quote. The main things that affect it are:
- Whether the work is at height
- Any working-time requirements on site
- Any mould that needs treating
- The number and length of the joints
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, send an email to info@mrmastic.co.uk and we will give you an honest view and a quote.
Helping us quote
When you contact us, these details help:
- Any access issues, like height or stairs
- Photos by email, if that is easy
- The type of property
- If someone has resealed it before
Every job is quoted individually. Just send an email to info@mrmastic.co.uk with the details, and photos are welcome.
Aftercare tips
Looking after new joints is easy:
- Check the joints during routine room inspections
- Give housekeeping the cure time for every room
- Note the date each area was done
- Book larger programmes for quieter times of year
Extract fans need to work. In internal bathrooms, a weak or broken fan lets moisture linger, and that is what keeps mould away.
Water from a failed shower seal can travel: through floors, into ceilings and across into corridors. Dealing with the joint early stops that spread.
What we are called out for in Sandbank
Plenty of commercial bathrooms have no window at all, so if the fan is weak, steam lingers and the sealant stays damp. Mould then takes hold in the silicone.
Any of these means the joints need attention:
- Water marks on ceilings under bathrooms
- Washroom sealant that looks dirty however often it’s cleaned
- Large numbers of bathrooms needing the same work
- Worktop sealant that has shrunk and stained
For buildings such as Sandbank Parish Church, its kitchen and washroom sealant needs looking after like anywhere else.
What your quote should include
- Who does the work, and how experienced they are
- When the joint can take water or movement
- Whether all the old sealant comes out first
- What product goes in the joint
