Fire rated sealant for homes and businesses in Comiston
A fire seal relies on being installed the way it was tested: correct depth, correct backing and a product suited to the surfaces. That detail is what we take care over, one gap at a time. We work on linear gaps, door frames and pipe & cable gaps, and common reasons people get in touch are sealant items on a fire risk assessment action list and fire seals that have cracked with movement.
In Scotland, building work comes under the Building (Scotland) Regulations and their technical handbooks. In Comiston, as anywhere, fire-rated sealant goes in to the product’s tested details and washroom sealant is chosen to cope with heavy use.
All of our work is guaranteed for twelve months.

When something else is needed
Sealant is not the answer to every problem, and we’ll tell you before any work starts. Sealant won’t put right:
- Sign-off of the building, which sits with building control or your assessor
- Large holes that need a different fire-stopping system
- A wall that is not a fire-resisting element to begin with
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly before booking.

Other services in Comiston
Different surfaces, different methods
Plasterboard walls
Holes in plasterboard are often cut roughly for services. Where a hole is bigger than the sealant’s tested range, it needs another approach and we will flag it.
Flats and HMOs
Conversions usually leave a mix of old and new service holes. We seal the ones on your specification with a tested product and the locations noted.

Common questions in Comiston
How do Scotland’s building regulations apply to fire-rated sealant in Comiston?
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 don’t certify buildings or carry out fire risk assessments, so your fire risk assessor or building control will advise on what’s needed.
I let a flat near Slateford station. Can you help?
Yes, rental work is part of what we do. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we will give you a clear quote.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do you seal gaps around fire door frames?
Yes. We seal the gap between the frame and the wall with a suitable fire-rated product, to the product’s details. The door leaf and its hardware need a door specialist.
Can you tell me which gaps need fire stopping?
No, assessment isn’t something we do. When your assessor or designer has set out what’s needed, we will quote for the sealant work on it.
Can you work in occupied buildings?
Yes. We work in flats, HMOs, schools, offices and other commercial buildings, including occupied ones. We agree access and the order of work with you first.
Do you cover Comiston?
Yes. We work in Comiston and the rest of Edinburgh. For a quote, email us at info@mrmastic.co.uk.
When to call us in Comiston
Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk in a place that needed a tested fire seal. It may look fine, but it isn’t a fire-rated seal.
These are the problems we’re asked about most:
- Linear gaps at the head of walls
- Seals cut through by electricians, plumbers or data installers
- Standard silicone or caulk in a fire-stopping gap
- Gaps left after a refit or conversion
For landlords with property near Slateford station, any gap left by new services in shared walls should be closed with a fire-rated product.
Questions to ask before you book
- Whether they’re fully insured
- Which sealant they’ll use, and why
- Whether you can choose the colour
- Is the old sealant removed completely?
How we quote for fire rated sealant
Your quote is based on your job. We take into account:
- The old material and how stubborn it is
- Which sealant suits the joint
- Access and height
- Whether there’s mould to deal with
Doing several joints on one visit is usually more efficient than separate visits. We will send you a clear quote for the lot.
What we need to know
There’s no need for technical detail. Just tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- Access, such as stairs, a lift or height
- The type of property
- Pictures of the joints, sent by email
To get a quote, drop us a line at info@mrmastic.co.uk with the location and a short description of the problem. We will give you a clear price before any work starts.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Ask which product was used before you paint
- Plan fire stopping into any work that goes through walls or floors
- Look in service cupboards and ceiling voids from time to time
Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. Later work is a common cause of damaged fire stopping.
It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole and the list grows.
What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a handful of gaps, and longer for a whole building, and the area is left clean. For a tenement in Comiston, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. It helps to know which it is when you get in touch.
- Before starting, we go through the specification or action list with you.
- We measure every gap and note what it’s in and what passes through.
- Any non-fire-rated filler is removed.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used for your files.
Preparing for the visit
- Tell us about any water getting in
- Tell us about any previous sealing or DIY attempts
- Keep pets and children clear of the area while we work
