Guest bathrooms are cleaned every day and used by different people every night, so sealant there has a hard life. We work through rooms in batches, so only a few are out of use at once. Common call-outs are for failed floor-level joints in accessible wet rooms and black, stained silicone in guest bathrooms, across rental portfolios, welfare facilities and student & care accommodation.

Common questions in Dunoon
Can you help a landlord with a rental near Inverkip station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
Do you work for hotels and guest houses in Dunoon?
Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.
Do the sealants smell?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Where do you work from?
Our base is Crawley. We work across South East England, London and Scotland.
What does commercial sealant cost?
Size, access and the old material all affect the cost. Ask us for a quote.
Is out-of-hours working possible?
Early starts and out-of-hours work can be arranged. Tell us what you need when you ask for a quote.
Other services in Dunoon
Do you need commercial sealant in Dunoon?
Commercial bathrooms get far more use than domestic ones, and daily cleaning with strong chemicals wears sealant down. So the silicone ages faster than it would at home.
Look out for any of the following:
- Failed floor-level joints in accessible wet rooms
- Mouldy washroom sealant that staff and guests notice
- Repeated reseals that don’t last
- Failed joints in office kitchens and tea points
If you look after a church, hall or community building such as St John’s Church (Dunoon), halls and community kitchens see heavy use, and their sealant shows it.

For landlords and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Letting agents and landlords in Dunoon can book us as well as householders. Sealant work between tenants keeps a property looking cared for.
DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
What affects the cost of commercial sealant
The price is agreed before any work begins. It takes into account:
- The number of rooms or windows
- When we can work, for business premises
- The amount of work
- The old material and how stubborn it is
What you pay reflects the work, not a rough estimate. That is why we ask about the job first.
What we need to know
Photos help, but a description is a good start. Try to tell us:
- A few pictures by email, if you can
- Whether it’s a home or a business
- Any access issues, like height or stairs
- Where the job is, and your postcode
Every job is quoted individually, so start by telling us what you need. Simply email us at info@mrmastic.co.uk and describe the job and send photos if you have them.
How the job changes by surface
Welfare facilities
Busy staff showers wear sealant out quickly. We reseal with anti-fungal sanitary silicone, including accessible wet rooms.
Rental portfolios
Landlords and agents can have several properties resealed in one programme, with each one done when access suits.
What happens on the day
You do not need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the job takes a few hours per room, so whole buildings are phased in most cases. Around Dunoon, distance and access matter more than parking. Let us know how to find you and how to reach the joints.
- We agree a programme with you: which rooms, in what order, at what times.
- We go through your site’s paperwork needs, such as RAMS, before work begins.
- In each room, the old bead comes out and the joint is cleaned and treated.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealant elsewhere.
- Rooms are handed back in order, each with its cure time.
How to prepare
- Mention any tricky access
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about parking restrictions

How to look after the new joints
Aftercare is simple:
- Check the joints during routine room inspections
- Get split or lifting joints looked at early
- Report broken fans quickly
- Log resealing so you know what’s due
Make it easy for staff to flag a failing joint. A small gap caught quickly is a short fix.
A room that can’t be let or used is lost income. Small sealant faults caught early can be fixed between bookings or tenancies, instead of turning into a leak that closes the room.
