Fire rated sealant for homes and businesses in Corstorphine
Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap. Common call-outs are for fire seals that have cracked with movement and gaps around pipes and cables through fire-resisting walls, on service penetrations, plasterboard & masonry and linear gaps.
In Scotland’s cities, hotels and student accommodation need sealant work done without emptying the building, so jobs in Corstorphine can be programmed room by room, with out-of-hours working possible to arrange.
Your job is guaranteed for a year, as with all our work.

Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Why act early in Corstorphine
Items left open on a fire risk assessment tend to come back at the next review. Getting them done and written up means you can show the action was taken. Scottish rain finds any gap around a frame or wall joint, and in Corstorphine, damp can spread through stone and plaster before anyone sees it.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please email us at info@mrmastic.co.uk and we will talk you through it.

What sealant work cannot fix
New sealant can’t fix everything, and we’d rather say so up front. It will not solve:
- Fire risk assessments, which need a qualified assessor
- Big openings where sealant alone isn’t the tested solution
- 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.
Joints and surfaces we work on
- Linear gaps
- Door frames
- Pipe & cable gaps
- Service penetrations
- Plasterboard & masonry
- Flats & HMOs
Surface by surface
Masonry and concrete
Holes through concrete and block are rarely neat. We check the gap size around the service against the product’s tested range.
Linear gaps
A linear joint may need to allow for movement as well as fire. We choose a product and depth that suit the gap and the movement, following the tested detail.
When to call us in Corstorphine
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.
It’s worth asking for a quote if you see:
- Open joints along the top of partitions
- Cracked or shrunken fire-rated sealant
- Holes left by a change of layout
- Fire stopping disturbed by later work
Letting a property close to South Gyle station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Questions from Corstorphine
Do you work for landlords with property near South Gyle station?
Yes. We work for letting agents and landlords as well as homeowners. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
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’s 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.
Will we have a record of what was sealed?
Yes. We note each location and the product that went in.
Can you work in occupied buildings?
Yes, in flats, HMOs, schools, offices and other buildings, occupied or empty. Tell us how the building is used and we will plan around it.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What does intumescent mean?
An intumescent sealant expands when it gets hot. It’s one type of fire-rated sealant; which product suits depends on the gap, the substrate and the service.
Is it OK to seal over 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.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Fire rated sealant in Corstorphine: local notes
If you run a hotel, guest house or holiday let in a coastal place like Corstorphine, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. Corstorphine has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed.
For buildings such as Corstorphine Collegiate Church, service openings in its walls need the right fire-rated sealant, as in any building. Schools such as Craigmount High School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment.

What happens on the day
There’s no need to move everything out, just the space around the work. We protect the rest, and the work takes from a few hours to a few days, depending on the number of gaps and the access for a typical job. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In Corstorphine, it helps to know the floor, the door entry arrangements and the nearest parking.
