How we handle fire rated sealant in Kilmun
In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. One new cable or pipe can leave a gap that nobody goes back to seal. Those are the gaps we close, using a tested fire-rated product. If you’re dealing with gaps filled with a product that isn’t fire-rated and open joints along the top of partitions, we can put it right, whatever the surface.
Work in a place like Kilmun is planned ahead, journey included, so the job can fit around guests, residents or opening hours where possible.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Fire rated sealant in Kilmun: local notes
If you run a hotel, guest house or holiday let in a coastal place like Kilmun, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. Scotland has its own building regulations, the Building (Scotland) Regulations, with technical handbooks. We install fire-rated sealant to the product’s tested details; we don’t certify buildings or carry out fire risk assessments.
Community buildings like St Munn's Parish Church are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

Kilmun: your questions answered
Is Kilmun within the area you cover?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Can you do fire rated sealant in Kilmun?
Yes. Our work covers the whole of Scotland, and Kilmun is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.
Can you tell me how many minutes the seal will last?
We do not give ratings or certificates for our work. Your specification sets the requirement, and we apply a product tested for it.
What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We’ll tell you what we’re using and why.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
Do you seal gaps around fire door frames?
Yes. We often seal open gaps hidden behind the architrave. Doors, seals and closers need a door specialist.
Can tenants book the work?
We’re happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
Is intumescent sealant the same as fire-rated sealant?
An intumescent material expands when it’s heated. Intumescent sealants are a type of fire-rated sealant.
Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Why it’s worth doing now in Kilmun
An unsealed gap lets smoke and fire get round a wall that was built to hold them back. Sealing it properly restores what the wall was there to do, and the sealing itself is often a contained piece of work. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.

Honest limits
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- Problems with the door itself rather than the gap around the frame
- Issuing a fire rating or certificate for a building
- Large holes that need a different fire-stopping system
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think before booking.

The process
When we arrive, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work begins. Most jobs take a few hours for a handful of gaps, and longer for a whole building. Around Kilmun, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- Anything that is not fit for the job comes out, and the gap is cleaned.
- Backing or fill is fitted where the product’s tested detail calls for it.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- Locations and products are noted so you have them on file.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Tell us about any previous sealing or DIY attempts
- Keep pets and children clear of the area while we work

Related advice
When to call us in Kilmun
Buildings are refitted and reconfigured over the years. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.
The most common problems we see are:
- Unsealed gaps where pipes and cables go through a wall
- Linear gaps at the head of walls
- Sealant items on a fire risk assessment action list
- Seals cut through by electricians, plumbers or data installers
For site and facilities teams at buildings such as Dunoon Grammar School, gaps opened by contractors for new cabling are a common finding in schools and offices.
Questions to ask before booking
- How long the guarantee is
- How long to leave it before use
- Whether they seal over old material or remove it
- What happens if the job turns out different
How to look after the new joints
Aftercare is simple:
- Include hidden areas like risers in routine checks
- Keep pictures of seals that will be hidden
- Don’t paint over fire sealant until it has cured
- Tell trades working in the building that fire seals must be put back
Do not drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.
It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole and the list grows.
