Fire rated sealant in Nerston, done properly
Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. Anything unsuitable comes out first and reseal with a fire-rated product tested for that kind of gap. If you have open joints along the top of partitions and sealant items on a fire risk assessment action list, we can put it right, on flats & HMOs, door frames and linear gaps alike.
Work in a place like Nerston is planned ahead, journey included, so it can be fitted around bookings or opening times where possible.
Every job is covered by a one-year guarantee.

Commercial buildings in Nerston
Scotland has its own building regulations, the Building (Scotland) Regulations, with technical handbooks. Fire-rated sealant is installed to the manufacturer’s tested details; we do not certify buildings or carry out fire risk assessments.
If you let a flat or house near East Kilbride station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

More services for Nerston
Different surfaces, different methods
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.
Service penetrations
New gaps tend to show up where services have been added. We clean out what’s there and reseal to the right depth over any backing the detail calls for.
Looking after it afterwards
To keep the joints looking good and working properly:
- Tell trades working in the building that fire seals must be put back
- File the fire-stopping record where your assessor can find it
- Photograph sealed gaps before they’re covered up
- Don’t paint over fire sealant until it has cured
Avoid covering a sealed gap with anything that is not part of the tested detail. If it needs repair, use the same type of product. We can tell you which product we used.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is usually a straightforward job.
When something else is needed
New sealant can’t fix everything, and we’d rather say so up front. It won’t solve:
- Problems with the door itself rather than the gap around the frame
- Deciding what fire stopping a building needs
- Issuing a fire rating or certificate for a building
If in doubt, email us at info@mrmastic.co.uk and we will say what we think before you book.
Surfaces we seal
- Door frames
- Flats & HMOs
- Plasterboard & masonry
- Service penetrations
- Linear gaps
- Pipe & cable gaps
When to call us in Nerston
Many open fire-stopping gaps are made after the building is finished. Electricians, plumbers and data installers drill through walls and ceilings and the hole round the new service is not always sealed again.
People normally contact us after spotting something like this:
- Seals cut through by electricians, plumbers or data installers
- Ordinary sealant used where a fire-rated product was needed
- Open gaps behind door architraves
- Unsealed gaps where pipes and cables go through a wall
Managing a site like St Andrew's and St Bride's High School? Then service openings in fire-resisting walls need checking after any refurbishment.

Common questions in Nerston
Do you cover smaller places like Nerston?
Yes. Nerston is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near East Kilbride station. Can you help?
Yes. We work for landlords and agents as well as homeowners. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we’ll send you a clear quote.
How long does the job take?
Typically it takes anything from a few hours to several days, depending on how many gaps there are. Bigger jobs take longer, and we will tell you how long to expect.
How much does fire rated sealant cost in Nerston?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
Do you guarantee your work?
Yes, for a year. If anything isn’t right with the work within the year, let us know and we will sort it.
Will we have a record of what was sealed?
Yes. We record the locations we’ve sealed and the products used to keep with your fire safety documents.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
The process
On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes a few hours for a handful of gaps, and longer for a whole building from start to finish. Outdoor work around Nerston depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- We measure every gap and note what it’s in and what passes through.
- Any non-fire-rated filler is removed and the faces cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used.
Before we arrive
- Clear items away from the joints we are working on
- For business premises, tell us about site rules or sign-in
- Let us know about earlier repairs to the joints
Getting a quote
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. Whenever you’re ready, send an email to info@mrmastic.co.uk.
Advice
Why deal with it now?
For some gaps, sealant is not the right answer and another system is needed. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. If a gap is not suitable for sealant, we’ll tell you. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
