What fire rated sealant looks like in Dalserf
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; we do not certify buildings or carry out fire risk assessments.
Managing a site like Larkhall Academy? Then fire-stopping around service openings should be restored whenever new services go in. Rented homes near Larkhall station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Fire rated sealant in Dalserf, done properly
Door frame gaps, linear joints and holes around services all have their own details. Measuring the gap and checking what it’s made of comes first, then apply it to the depth its tested detail calls for. We work on linear gaps, door frames and service penetrations, and the jobs we see most are new service routes left unsealed after building work and unsealed gaps around fire door frames.
Commercial work around smaller Scottish places tends to mean hotels, guest houses, schools and halls rather than offices. Each needs sound sealant in its washrooms and kitchens, and fire-rated joints kept in good order.
A one-year guarantee comes with the work, just as it does everywhere we cover.

How the visit works
On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before work begins. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. Somewhere like Dalserf may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- 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.
- Where the tested detail needs backing or fill, we fit it.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Finally, we list where we worked and what we used, for your records.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Mention any tricky access
- On commercial sites, let us know about site rules

Advice
What the job involves on each surface
Door frames
The gap between a door frame and the wall around it needs sealing as well as the door itself. We seal that gap with a fire-rated sealant suited to the frame and wall.
Linear gaps
Head-of-wall gaps are often hidden above suspended ceilings. We seal them along their full length.
What affects the cost of fire rated sealant
We do not publish a price list, because no two jobs are the same. The quote depends on:
- How easy the joints are to reach
- Mould in or behind the old joints
- The number and length of the joints
- The product the joint needs
Combining jobs into one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will give you a clear quote for the lot.
Asking for a quote
Before you ask for a quote, have a think about:
- If it’s domestic, commercial or a hotel
- Whether it has been sealed before
- The rough size of the job
- What the problem is, such as mould, gaps, leaks or cracking
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we’ll explain what’s involved and send you a clear quote.
What we are called out for in Dalserf
A lot of fire stopping is out of sight: in ceiling voids, service risers and behind boxing. Out of view, damage sits unnoticed until someone inspects.
Any of these means the joints need attention:
- Sealant items on a fire risk assessment action list
- Ordinary sealant used where a fire-rated product was needed
- Open holes round services passing through fire walls
- Old fire sealant that has split or come away
If you look after a church, hall or community building such as Dalserf Kirk, service openings in its walls need the right fire-rated sealant, as in any building.
What your quote should include
- What happens if they find a problem under the old sealant
- Whether VAT is included
- Is the old sealant removed completely?
- Whether the sealant suits the joint
Your questions about fire rated sealant in Dalserf
Is Dalserf within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Are the rules for fire-rated sealant different in Scotland?
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.
Are you insured?
Yes. We’re fully insured for every job we do.
Do you carry out fire risk assessments?
No. Your fire risk assessor, designer or building control decides that. Our job is applying the sealant to their specification.
Can you do several jobs on one visit?
Yes, we can. More than one area can be quoted together.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
How long will you be here?
As a guide, most jobs take from a few hours to a few days, depending on the number of gaps and the access. Larger jobs naturally take longer.
Do you guarantee your work?
Yes. Each job is guaranteed for twelve months, wherever you are.
Looking after it afterwards
To keep the joints looking good and working properly:
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Ask which product was used before you paint
- Tell trades working in the building that fire seals must be put back
- Report cracked or damaged seals as soon as you notice them
Include fire stopping in your regular building checks. Look for cracks, gaps or sealant that has been cut or pulled out and have them put right.
It’s easiest to seal gaps while they’re few and easy to reach. Over time, more work adds more holes and the job gets bigger.
What we cannot put right
We will always be straight with you, so here’s what sealant can’t fix:
- Large holes that need a different fire-stopping system
- Issuing a fire rating or certificate for a building
- Doors that are not fire doors in the first place
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly before you book.
Surfaces we seal
- Linear gaps
- Plasterboard & masonry
- Service penetrations
- Door frames
- Flats & HMOs
