Fire rated sealant in Dunnet
In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. A new cable run or a replaced pipe can leave an open hole behind. Those are the gaps we close, using a tested fire-rated product. We are often asked to deal with seals cut through by electricians, plumbers or data installers and fire seals that have cracked with movement, on linear gaps, flats & HMOs and service penetrations.
In a smaller place like Dunnet, commercial jobs are more likely to be a hotel, guest house, school, surgery or community hall than an office block. All of them have washrooms, kitchens and fire-rated joints that need looking after.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

Why it’s worth doing now in Dunnet
Paying for fire stopping that has to be redone is a false economy. Work that does not follow the tested detail may have to come out again when the building is next checked. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
The cost depends on how much there is to do, how much old material has to come out and access to the work. You will have a clear quote before any work starts.

When it is not the sealant
We won’t take on work that won’t last, so these are the limits:
- Fire doors that need new seals, closers or hardware
- Construction that doesn’t provide fire resistance on its own
- Fire risk assessments, which need a qualified assessor
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Door frames
- Plasterboard & masonry
- Service penetrations
- Flats & HMOs
- Pipe & cable gaps
- Linear gaps
Different surfaces, different methods
Masonry and concrete
Preparation counts on brick, block and concrete. We brush and vacuum the gap and use backing where the detail needs it before the sealant goes in.
Service penetrations
A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. Each one is sealed to the product’s tested detail and we flag any that need another system.
Your questions about fire rated sealant in Dunnet
Can you do fire rated sealant in Dunnet?
Yes, Dunnet is within the area we cover. We work across all of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear quote.
How do Scotland’s building regulations apply to fire-rated sealant in Dunnet?
Scotland has its own building regulations, the Building (Scotland) Regulations, with their own technical handbooks. Fire-rated sealant has to go in to the product’s tested details, and we follow them. We don’t certify buildings or carry out fire risk assessments, so your fire risk assessor or building control will advise on what’s needed.
Are you fully insured?
Yes. We are fully insured.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
Can you tell me how many minutes the seal will last?
That is not something we state or certify. Your specification sets the requirement, and we apply a product tested for it.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that normally means someone at home.
Can you work in occupied buildings?
Yes. We work in flats, HMOs, schools, offices and other commercial buildings, including occupied ones. We agree access and the order of work with you first.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

What fire rated sealant looks like in Dunnet
For seaside hotels, guest houses and holiday lets around Dunnet, 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. In Scotland, building work comes under the Building (Scotland) Regulations and their technical handbooks. We install fire-rated sealant to the product’s tested details; we do not certify buildings or carry out fire risk assessments.

Common problems we fix in Dunnet
Sealant applied too thin, without the backing its detail needs, or onto dust won’t perform as it was tested. We see plenty of fire stopping that was hurried.
Any of these means the joints need attention:
- Unsealed gaps around fire door frames
- Seals cut through by electricians, plumbers or data installers
- Gaps left after a refit or conversion
- Open holes round services passing through fire walls
If you look after a church, hall or community building such as Dunnet Church, service openings in its walls need the right fire-rated sealant, as in any building.

How it works
All our tools and materials come with us in the van. After a quick look at the joints together, we protect the area and start. It normally takes anything from a few hours to several days, depending on how many gaps there are. Outdoor work around Dunnet depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- We measure every gap and note what it’s in and what passes through.
- Unsuitable material such as ordinary foam or silicone is cut out and the gap cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used for your files.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Let us know about parking restrictions
- Mention if the joints have been sealed before
