Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
How we handle fire rated sealant in An t-Ob
Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. 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. Common call-outs are for old fire sealant that has split or come away and joints picked up in a fire-stopping survey, across flats & HMOs, door frames and service penetrations.
Commercial work around smaller Scottish places tends to mean hotels, guest houses, schools and halls rather than offices. All of them have washrooms, kitchens and fire-rated joints that need looking after.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

What happens if it’s left?
For some gaps, sealant is not the right answer and another system is needed. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. If a gap isn’t suitable for sealant, we will tell you. In an older home around An t-Ob, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, email us at info@mrmastic.co.uk for an honest opinion and a quote.

Keeping the joints in good condition
Looking after new joints is easy:
- Include hidden areas like risers in routine checks
- Keep pictures of seals that will be hidden
- Get damaged fire seals looked at promptly
- File the fire-stopping record where your assessor can find it
Keep the record we give you with the building’s fire safety documents. It saves time at the next inspection or assessment.

FAQs for An t-Ob
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 do fire risk assessments; your assessor or building control can tell you what’s required.
Is An t-Ob in your area for fire rated sealant?
Yes, An t-Ob is within the area we cover. We work across all of Scotland. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing.
Should I try DIY first?
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.
Will you assess my building’s fire safety?
No. That is for a fire risk assessor, designer or building control. Our job is applying the sealant to their specification.
Do you take on fire stopping in schools and offices?
Yes, in flats, HMOs, schools, offices and other buildings, occupied or empty. Let us know the building’s hours and we will plan the work to suit.
Do you guarantee your work?
Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.
Is intumescent sealant the same as fire-rated sealant?
Intumescent means it swells when heated. Intumescent sealants are one kind of fire-rated sealant; which product suits depends on the gap, the substrate and the service.
Can I choose the sealant colour?
We help you choose a colour that suits. The product needed can limit the range.
