About our fire rated sealant in Twynholm
Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap. Typical jobs include gaps flagged on a fire risk assessment and damaged fire sealant left by other trades, on plasterboard & masonry, door frames and flats & HMOs.
For a place like Twynholm, the journey and timings are planned in advance, so it can be fitted around bookings or opening times where possible.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What we cannot put right
We’d rather tell you now than do work that will not last, so these are the limits:
- Big openings where sealant alone isn’t the tested solution
- Certifying a building or signing off its fire safety
- Fire doors that need new seals, closers or hardware
If you’re not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer.
Surfaces we seal
- Flats & HMOs
- Plasterboard & masonry
- Service penetrations
- Pipe & cable gaps
- Linear gaps
- Door frames
Do you need fire rated sealant in Twynholm?
Gaps also open up as buildings move: a seal that cracks or pulls away leaves a path for smoke. Damage from cleaning, knocks and maintenance adds to it.
People normally contact us when they notice one of these:
- Standard silicone or caulk in a fire-stopping gap
- Unsealed gaps where pipes and cables go through a wall
- Door frames with gaps between frame and wall
- Seals cut through by electricians, plumbers or data installers
Managing a site like Kirkcudbright Academy? Then service openings in fire-resisting walls need checking after any refurbishment.
What your quote should include

- Whether you can choose the colour
- What happens if they find a problem under the old sealant
- Whether all the old sealant comes out first
Why deal with it now?
Squirting in whichever sealant is nearest does not make a fire seal. Fire-rated products are tested in set gap sizes, depths and substrates, so both the product and the method matter. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.
Why choose Mr Mastic in Twynholm
- Old sealant always removed completely
- Tidy, careful work
- Sanitary silicone with an anti-fungal additive in wet areas
- Arbo and Everbuild products

Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
A DIY attempt does not rule out a professional job. We cut it out and start again.
What happens on the day
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a handful of gaps, and longer for a whole building. Outside jobs in Twynholm need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Old or unsuitable sealant is cut out and the gap 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.
- We record the locations and products used for your records.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Keep pets and children clear of the area while we work
- Tell us about any previous sealing or DIY attempts

Common questions in Twynholm
Can you do fire rated sealant in Twynholm?
Yes, Twynholm is within the area we cover. We work across all of Scotland. You can email us at info@mrmastic.co.uk and tell us what needs doing, and we’ll give you a clear quote.
Are the rules for fire-rated sealant different in Scotland?
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.
Do you remove the old sealant?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
What’s the difference between intumescent and fire-rated sealant?
An intumescent material expands when it’s heated. Intumescent sealants are a type of fire-rated sealant and which one is used depends on the job.
Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.

Commercial buildings in Twynholm
If you run a hotel, guest house or holiday let in a coastal place like Twynholm, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. In Scotland, building work comes under the Building (Scotland) Regulations and their technical handbooks. Fire-rated sealant is installed to the manufacturer’s tested details, though we don’t certify buildings or do fire risk assessments.
If you look after a church, hall or community building such as Twynholm Parish Church And Graveyard, service openings in its walls need the right fire-rated sealant, as in any building.

Different surfaces, different methods
Linear gaps
Long, narrow gaps appear where walls meet slabs and ceilings. We seal them to the tested detail, with backing where it’s needed.
Door frames
The gap between a door frame and the wall around it needs sealing as well as the door itself. We fill it with a fire-rated product suited to the materials either side.
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Plan fire stopping into any work that goes through walls or floors
- Never patch a fire seal with standard sealant
- Ask every contractor to reseal any fire stopping they disturb
- Keep the record of products and locations with your fire safety documents
Leave the sealant to cure fully before painting near it. Not every fire-rated sealant takes paint.
If a fire risk assessment has flagged a gap, don’t leave it for the next one. Have it sealed, then keep the record.
