How we handle fire rated sealant in Branahuie
We don’t assess buildings or decide what fire stopping is needed; that comes from your fire risk assessor, designer or building control. Our part is applying the specified sealant carefully, to the right depth and with the right backing. We work on linear gaps, service penetrations and flats & HMOs, and people most often call us about open gaps behind door architraves and ordinary sealant used where a fire-rated product was needed.
For holiday lets, guest houses and community buildings in or near Branahuie, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
Whatever the size of the job, it’s backed by our one-year guarantee in Branahuie and across Na h-Eileanan Siar.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Never patch a fire seal with standard sealant
- Check whether a sealant can be painted before decorating over it
- Keep photos of seals that will be hidden
- File the fire-stopping record where your assessor can find it
Follow the cure time we give you before decorating over the sealant. Not every fire-rated sealant takes paint, so ask us which we used.
Any job that breaks through a wall or ceiling should include resealing. Catching it then saves a separate visit later.
Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
How it works
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from a few hours to several days, depending on how many gaps there are. Outside jobs in Branahuie need a dry day, because sealant won’t bond to a wet joint, 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.
- Each gap is measured and its substrate and service noted.
- Any non-fire-rated filler is removed and the gap cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used for your records.
Before we arrive
- Let us know about stairs, lifts or work at height
- On commercial sites, let us know about site rules
- Tell us about any previous sealing or DIY attempts

Advice
What we’re called out for in Branahuie
In some buildings the gap was filled with the wrong thing in the first place: ordinary expanding foam, standard silicone or decorators’ caulk in a place that needed a tested fire seal. It may look fine, but it is not a fire-rated seal.
Most people get in touch after spotting one of these:
- Door frames with gaps between frame and wall
- Gaps filled with a product that isn’t fire-rated
- Linear gaps at the head of walls
- Cracked or shrunken fire-rated sealant
For jobs in and around Branahuie, choosing the right material for each joint is as important as a tidy finish.
Questions to ask before you book
- Whether the sealant suits the joint
- What happens if the job turns out different
- What preparation is included
- What the quote includes, VAT included or not
Surface by 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.
Masonry and concrete
Masonry is dusty and porous, so preparation matters. We brush and vacuum the gap and use backing where the detail needs it before applying the sealant.

FAQs for Branahuie
How do Scotland’s building regulations apply to fire-rated sealant in Branahuie?
Building work in Scotland comes under the Building (Scotland) Regulations and their 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.
Can you do fire rated sealant in Branahuie?
Yes. Our work covers the whole of Scotland, and Branahuie is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
What does fire rated sealant cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Can I use normal mastic around a pipe through a fire wall?
No. Ordinary silicone, caulk or foam is not tested as fire stopping. We cut it out and reseal with a fire-rated product.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. Then drop us a line at info@mrmastic.co.uk.
Where are you based?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do you guarantee your work?
Yes. There’s a 12-month guarantee on every job.
Why it’s worth doing now in Branahuie
Fire-rated sealants are less forgiving than ordinary ones. How it’s installed changes how it performs, so we follow the maker’s details on every gap. In a place like Branahuie, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we will explain what it covers.

What sealant work can’t fix
New sealant cannot fix everything, and we will tell you before work begins. It won’t solve:
- Deciding what fire stopping a building needs
- Issuing a fire rating or certificate for a building
- Openings too large for sealant, which need batts, boards or another system
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly.
