Fire Rated Sealant in Liff
Problem with your fire-stopping gaps in Liff? We remove the old material, prepare the joints and seal them properly, with a 12-month guarantee.
- Damaged fire sealant left by other trades
- Fire seals that have cracked with movement
- Unsealed gaps where pipes and cables go through a wall
Why it’s worth doing now in Liff
A quick fill with any sealant to hand is not fire stopping. A fire-rated product only performs as tested when it’s installed to its tested detail, which is why we match the product and the method to each gap. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
What you get with us
- Experience in homes, commercial sites and hotels
- Trusted Arbo and Everbuild sealants
- An ARBOMaster approved applicator
- Any old sealant cut out fully, not covered over

Fire rated sealant in Liff, done properly
A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. We check the size and the substrate before choosing the product, then apply it to the depth its tested detail calls for. We work on pipe & cable gaps, plasterboard & masonry and flats & HMOs, and the jobs we see most are sealant items on a fire risk assessment action list and gaps where walls meet ceilings or slabs.
If you look after holiday lets, a guest house or a community building in or near Liff, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
There’s a 12-month guarantee on every job, whatever its size.

Signs you need fire rated sealant in Liff
Buildings are refitted and reconfigured over the years. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.
Any of these means the joints need attention:
- Open holes round services passing through fire walls
- Standard silicone or caulk in a fire-stopping gap
- Seals cut through by electricians, plumbers or data installers
- Holes left by a change of layout
Managing a site like Menzieshill High School? Then gaps opened by contractors for new cabling are a common finding in schools and offices.
Before you book anyone
- The length of the guarantee
- Is the old sealant removed completely?
- What happens if the job turns out different
- Who turns up on the day
DIY versus a professional finish
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. Everything old must be removed first.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
How we quote for fire rated sealant
Some jobs are bigger than they look, and some smaller. The main factors:
- The number and length of the joints
- How many areas need sealing
- Working hours on commercial sites
- Whether the work is at height
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.
What to tell us for a quote
When you call or email, it’s useful to know:
- Any access issues, like height or stairs
- Whether it’s a home or a business
- Pictures of the joints, sent by email
- Roughly how big the job is
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Look in service cupboards and ceiling voids from time to time
- Photograph sealed gaps before they’re covered up
- Flag any open gap you spot round a pipe or cable
- Tell trades working in the building that fire seals must be put back
Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some cannot and we will tell you which one you have.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is normally a straightforward job.
Honest limits
Before you book, it’s worth knowing the limits:
- Certifying a building or signing off its fire safety
- Problems with the door itself rather than the gap around the frame
- Big openings where sealant alone isn’t the tested solution
If you are not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer before booking.

FAQs for Liff
Are the rules for fire-rated sealant different in Scotland?
Building work in Scotland comes under the Building (Scotland) Regulations and their technical handbooks. Whatever the rules, fire-rated sealant has to be installed to the manufacturer’s tested details, and that is how we fit it. We do not certify buildings or do fire risk assessments; your assessor or building control can tell you what’s required.
Is Liff within the area you cover?
Yes, Liff is covered. We work across all of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Are you insured?
Yes, we are fully insured.
Do you remove the old sealant?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Do you take on fire stopping in schools and offices?
Yes. We regularly work in flats, HMOs, schools and offices while they’re in use, with access planned around residents or staff. Out-of-hours work can be arranged.
Can you do several jobs on one visit?
Yes. More than one area can go on one quote.
Can you seal over the old sealant?
No, it won’t last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.

If you run a hotel, guest house or holiday let in a coastal place like Liff, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks.
