Related advice
Fire rated sealant for homes and businesses in Knock
Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. Each gap is sealed to the product maker’s tested detail for its size and substrate, and we can record what went where. Typical jobs include damaged fire sealant left by other trades and sealant items on a fire risk assessment action list, on pipe & cable gaps, service penetrations and door frames.
In a smaller place like Knock, commercial jobs are more likely to be a hotel, guest house, school, surgery or community hall than an office block. Each needs sound sealant in its washrooms and kitchens, and fire-rated joints kept in good order.
You’re covered for a year from the day we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

Questions from Knock
How do Scotland’s building regulations apply to fire-rated sealant in Knock?
Building work in Scotland comes under the Building (Scotland) Regulations and their technical handbooks. Fire-rated sealant has to go in to the product’s tested details, and we follow them. We do not certify buildings or carry out fire risk assessments, so your fire risk assessor or building control will advise on what’s needed.
Can you do fire rated sealant in Knock?
Yes. Our work covers the whole of Scotland, and Knock is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job.
Can I choose the sealant colour?
Yes. White, clear and grey are common, and other colours are available for many products, and we’ll agree it with you first.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
What’s the difference between intumescent and fire-rated sealant?
An intumescent sealant expands when it gets hot, helping close the gap. It’s one type of fire-rated sealant; which product suits depends on the gap, the substrate and the service.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Can you give us a record of the work?
Yes. Locations and products are written up when we finish. Tell us if your assessor needs it in a particular format.
Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Allow for resealing whenever new services are run
- Make resealing part of every contractor’s brief
- Report cracked or damaged seals as soon as you notice them
- Check risers, ceiling voids and cupboards during building checks
Tell other trades that the gaps have been sealed, and ask them to reseal anything they cut through. Later work is a common cause of damaged fire stopping.
Small gaps around services are simple to deal with while there are only a few. Over time, more work adds more holes and the job gets bigger.
Landlords, agents and businesses in Knock
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will quote.
We also work for property managers and facilities teams. We can quote a run of properties together.
Leave it or put it right?
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 work involved is often modest. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please email us at info@mrmastic.co.uk and we’ll talk you through it.

When to call us in Knock
Gaps around door frames are easily missed. The gap between the frame and the wall is hidden behind the architrave, so it can be left open when a door is replaced.
It’s worth asking for a quote if you see:
- Seals cut through by electricians, plumbers or data installers
- Fire seals that have cracked with movement
- Gaps flagged on a fire risk assessment
- Door frames with gaps between frame and wall
Around Knock, as everywhere, fire rated sealant is only as good as the preparation behind it.
