How we handle fire rated sealant in Larkhall
Bigger jobs can be worked through in stages, flat by flat or floor by floor, with each location and product recorded. It gives you a list to keep with the building’s fire safety documents. Typical jobs include damaged fire sealant left by other trades and joints picked up in a fire-stopping survey, on plasterboard & masonry, linear gaps and door frames.
Scotland has its own building regulations, the Building (Scotland) Regulations, and fire-rated sealant has to go in to the manufacturer’s tested details. Whether it’s a hotel, a school or an office in Larkhall, that’s how it’s fitted.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

Surface by surface
Plasterboard walls
Plasterboard partitions are common in flats, offices and conversions. We use a product tested in that kind of wall for each gap size.
Masonry and concrete
Core-drilled and broken-out holes in concrete are often irregular. We measure the gap at its widest point to make sure it suits the product.
What we are called out for in Larkhall
Lots of unsealed gaps appear long after the building was completed. New cables, pipes and data runs go through walls and ceilings and the hole they leave doesn’t always get resealed.
Look out for these signs:
- Cracked or shrunken fire-rated sealant
- Open joints along the top of partitions
- Unsealed gaps where pipes and cables go through a wall
- Seals cut through by electricians, plumbers or data installers
For site and facilities teams at buildings such as Larkhall Academy, service openings in fire-resisting walls need checking after any refurbishment.

Larkhall questions
Can you do fire rated sealant in Larkhall?
Yes, Larkhall is within the area we cover. Our work covers the whole of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job.
How do Scotland’s building regulations apply to fire-rated sealant in Larkhall?
Scotland has its own building regulations, the Building (Scotland) Regulations, with their own 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 carry out fire risk assessments, so your fire risk assessor or building control will advise on what’s needed.
I rent my home. Can I book you?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Can ordinary silicone be used in a fire-stopping gap?
No. Standard sealants aren’t made or tested to stop fire. We cut it out and reseal with a fire-rated product.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned.
Can you give us a record of the work?
Yes. Locations and products are written up when we finish. If you need pictures or a set layout, ask when you get a quote.

Scotland has its own building regulations, the Building (Scotland) Regulations, with technical handbooks. Fire-rated sealant is installed to the manufacturer’s tested details, though we do not certify buildings or do fire risk assessments.
Community buildings like St Machan's Parish Church are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building. Letting a property close to Larkhall station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Why it’s worth doing now in Larkhall
A quick fill with any sealant to hand is not fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, which is why we match the product and the method to each gap. In flats with a shared stair in Larkhall, a leak from a failed seal can affect the flat below too, and that’s much harder to put right.
What you pay reflects the work, not guesswork. That’s why we ask about the job first and send you a clear quote before work begins.

The process
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes anything from a few hours to several days, depending on how many gaps there are, including the tidy-up. A visit in Larkhall needs three things planned: access, parking and where the work is. Outside work depends on the weather, as sealant needs a dry surface.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Anything that isn’t fit for the job comes out, and the gap is 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.
- Locations and products are noted so you have them on file.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Mention any sign-in or site rules at work premises
- Let us know about parking restrictions
Ask for a quote
Asking for a quote is easy: let us know the job and the location and its rough size. A few photos by email make the job easier to understand, and we will take it from there.

Honest limits
In fairness, there are a few things sealant won’t fix:
- Sign-off of the building, which sits with building control or your assessor
- A wall that is not a fire-resisting element to begin with
- Openings too large for sealant, which need batts, boards or another system
If you are not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer before you book.
