Fire rated sealant in Lenzie, done properly
Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. Each gap is sealed to the product maker’s tested detail for its size and substrate, and we can record what went where. If you’re dealing with gaps where walls meet ceilings or slabs and unsealed gaps where pipes and cables go through a wall, we can help.
Commercial jobs in a town like Lenzie range from shops and offices to schools, hotels and care homes, all with washroom, kitchen and fire-rated joints to look after.
Our work is backed for twelve months, in Lenzie and everywhere else we cover.

Lenzie questions
Do you work for landlords with property near Lenzie station?
Yes, rental work is part of what we do. Just send an email to info@mrmastic.co.uk and tell us about the property, and we’ll send you a clear quote.
Can you do fire rated sealant in Lenzie?
Yes, Lenzie is within the area we cover. We work across all of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we’ll send you a clear quote.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Can ordinary silicone be used in a fire-stopping gap?
No. It looks sealed but will not perform as fire stopping. Use a product tested for that gap and service, or ask us to do it.
How long does fire rated sealant take?
As a guide, most jobs take from a few hours to a few days, depending on the number of gaps and the access. Bigger jobs take longer, and we’ll say how long yours will take.
Do you carry out fire risk assessments?
No. That is for a fire risk assessor, designer or building control. Our job is applying the sealant to their specification.
What information do you need?
The location, the problem and the rough size of the job. If you can, email a few photos.

What else we do in Lenzie
How the job changes by surface
Service penetrations
Service penetrations are where new gaps often appear. We clean out what’s there and reseal to the right depth.
Door frames
Frame gaps are generally hidden behind the architrave. Where it’s open, we seal it to the product’s details for that gap size before the trim goes back.
When to call us in Lenzie
Door frames are a common weak spot. The gap between the frame and the wall is hidden behind the architrave, so it can be left open when a door is replaced.
If you can see any of these, it’s time to have the joints looked at:
- Cracked or shrunken fire-rated sealant
- Gaps filled with a product that isn’t fire-rated
- Gaps flagged on a fire risk assessment
- Gaps where walls meet ceilings or slabs
If you look after a building such as Kirkintilloch High School, service openings in fire-resisting walls need checking after any refurbishment.

What fire rated sealant looks like in Lenzie
Scotland has its own building regulations, the Building (Scotland) Regulations, with technical handbooks. We install fire-rated sealant to the product’s tested details; we don’t certify buildings or carry out fire risk assessments.
Rented homes near Lenzie station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product. For buildings such as Lenzie Old Parish Church, gaps around pipes and cables are worth checking after any building work there.

What happens on the day
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. It generally takes a few hours for a handful of gaps, and longer for a whole building. In a Scottish town like Lenzie, parking is normally straightforward, though older centres can be tighter. If you’re in a flat with a shared stair or a door entry system, let us know when you book.
- Access to each area is agreed so the work can run in order.
- We take out any damaged or unsuitable sealant.
- Gaps are cleaned of dust and loose material.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- We record what was done and flag anything that needs a different system.
How to prepare

Advice
How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- File the fire-stopping record where your assessor can find it
- Don’t fill fire-stopping gaps with ordinary foam or silicone
- Plan fire stopping into any work that goes through walls or floors
- Ask every contractor to reseal any fire stopping they disturb
Leave the sealant to cure fully before painting near it. Not every fire-rated sealant takes paint.
Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole and the list grows.
What we cannot put right
A few problems are outside what sealant work can do:
- 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 is not the tested solution
If you’re not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer before you book.
Surfaces we seal
- Plasterboard & masonry
- Pipe & cable gaps
- Door frames
- Flats & HMOs
- Linear gaps
- Service penetrations
Leave it or put it right?
Leaving a gap until a refurbishment comes round can mean years with it open. On its own, sealing it now is a small job and needn’t wait for anything else. Scottish weather finds any gap, and in a town like Lenzie, failed outside joints soon let damp into walls. Inside, a failed seal around a bath or shower lets water into floors and ceilings.
What it costs depends on the amount of work, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.
