Janetstown Fire Rated Sealant
Fire rated sealant across Janetstown and nearby, with old sealant always removed completely.
- Standard silicone or caulk in a fire-stopping gap
- Fire seals that have cracked with movement
- Unsealed gaps where pipes and cables go through a wall
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Fire rated sealant in Janetstown
Ordinary silicone or decorators’ caulk in a fire-stopping gap isn’t a fire-rated seal. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. We work on plasterboard & masonry, flats & HMOs and door frames, and the jobs we see most are gaps where walls meet ceilings or slabs and ordinary sealant used where a fire-rated product was needed.
For holiday lets, guest houses and community buildings in or near Janetstown, the washrooms and kitchens need the same care as any city building, and fire-rated joints should be kept in good order.
All of our work is guaranteed for twelve months, in Janetstown and everywhere else we cover.

Landlord and commercial work in Janetstown
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we’re fully insured.
We work for landlords and agents as well as householders. Sealant work between tenants is a simple way to keep a property in good order.
Honest limits
Sealant is not the answer to every problem, and we’ll tell you before work begins. Sealant won’t put right:
- Sign-off of the building, which sits with building control or your assessor
- A wall that isn’t a fire-resisting element to begin with
- Big openings where sealant alone is not the tested solution
If you are not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer.
Joints and surfaces we work on
- Pipe & cable gaps
- Service penetrations
- Flats & HMOs
- Door frames
- Linear gaps
- Plasterboard & masonry
When to call us in Janetstown
Gaps around door frames are easily missed. The gap between the frame and the wall is hidden behind the architrave, so it’s easy to leave unsealed when doors are changed.
It’s worth asking for a quote if you see:
- Open gaps behind door architraves
- Cracked or shrunken fire-rated sealant
- Standard silicone or caulk in a fire-stopping gap
- Holes left by a change of layout
If you look after a building such as Thurso High School, service openings in fire-resisting walls need checking after any refurbishment.

Aftercare tips
A little care helps the new joints last. Our advice:
- Allow for resealing whenever new services are run
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Tell trades working in the building that fire seals must be put back
- Keep the record of products and locations with your fire safety documents
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.
A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded so the item can be closed.

FAQs for Janetstown
How do Scotland’s building regulations apply to fire-rated sealant in Janetstown?
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 do not certify buildings or do fire risk assessments; your assessor or building control can tell you what’s required.
Can you help a landlord with a rental near Thurso station?
Yes, rental work is part of what we do. You can email us at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before we start.
Do you take on fire stopping in schools and offices?
Yes. Occupied flats, HMOs, offices and schools are all fine and we plan access around the people using them. Out-of-hours work can be arranged.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
Can ordinary silicone be used in a fire-stopping gap?
No. Standard sealants are not made or tested to stop fire. If it’s been used, we remove it and use the right product.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and you’ll get one quote.
What does intumescent mean?
Intumescent means it swells when heated, helping close the gap. It’s one type of fire-rated sealant; the right one depends on the gap and what passes through it.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
What affects the quote in Janetstown
The quote reflects the job in front of us. We look at:
- Any mould that needs treating
- How many rooms, windows or areas are involved
- The old material and how stubborn it is
- The number and length of the joints

- What the problem is, such as mould, gaps, leaks or cracking
- The address or postcode of the job

- Roughly how big the job is
There’s no standard price list. Instead, we give you a clear quote for your job. To arrange one, email us at info@mrmastic.co.uk.
The process
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a few hours for a handful of gaps, and longer for a whole building. In smaller Scottish places, parking is generally less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- We plan the order of work and access, floor by floor or flat by flat.
- We take out any damaged or unsuitable sealant.
- Dust and loose debris are cleaned from each gap.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
How to prepare
- Keep pets and children clear of the area while we work
- For business premises, tell us about site rules or sign-in
- Let us know about stairs, lifts or work at height
