- Gaps flagged on a fire risk assessment
- Standard silicone or caulk in a fire-stopping gap
- Gaps left after a refit or conversion
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Allow for resealing whenever new services are run
- Take photos of fire stopping before ceilings or boxing go back
- Store the list of sealed gaps with your building paperwork
- Ask which product was used before you paint
Include fire stopping in your regular building checks. Watch for cracking, gaps or seals that have been disturbed and have them put right.
Any job that breaks through a wall or ceiling should include resealing. Catching it then saves a separate visit later.
How we handle fire rated sealant in Bac
Landlords, managing agents and facilities teams use us for the sealant items on a fire risk assessment on buildings across Bac. Send us the list or the survey and we’ll quote for the fire-rated sealant work on it. If you are dealing with gaps flagged on a fire risk assessment and open joints along the top of partitions, we can put it right, whatever the surface.
Work in a place like Bac is planned ahead, journey included, so it can be fitted around bookings or opening times where possible.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

Honest limits
Sealant isn’t the answer to every problem, and we will tell you before any work starts. It won’t solve:
- Sign-off of the building, which sits with building control or your assessor
- Openings too large for sealant, which need batts, boards or another system
- Walls or floors that weren’t built to resist fire
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think.
Surfaces we seal
- Service penetrations
- Flats & HMOs
- Plasterboard & masonry
- Door frames
- Pipe & cable gaps
- Linear gaps
Surface by surface
Flats and HMOs
Conversions normally leave a mix of old and new service holes. The gaps on your list are sealed with a fire-rated product and the locations noted.
Linear gaps
Linear gaps run along the head of walls, at floor edges and between panels. They’re sealed with a fire-rated sealant over backing where the detail calls for it.
How the visit works
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and clear up. Most jobs take a few hours for a handful of gaps, and longer for a whole building. Outdoor work around Bac depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- 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 and the faces cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used for your records.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Move anything stored near the joints
- Let us know about stairs, lifts or work at height

Your questions about fire rated sealant in Bac
Is Bac within the area you cover?
Yes, smaller places are covered as well as towns. We work across all of Scotland, including the islands, where work is planned around ferry crossings. Just mention lanes, gates or anything else about the route when you book.
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 is how we fit it. We don’t certify buildings or do fire risk assessments; your assessor or building control can tell you what’s required.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Can I choose the sealant colour?
Most of the time, yes. We’ll explain which colours are available and agree one before any work starts.
Do you have insurance?
Yes. We’re fully insured, and we’ve been doing sealant work for more than 20 years.
Is intumescent sealant the same as fire-rated sealant?
Intumescent describes a material that swells in heat. Intumescent sealants are a type of fire-rated sealant.
Do you carry out fire risk assessments?
No. We follow the requirements from your assessor, designer or building control, and apply each product to its tested details.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

What affects the cost of fire rated sealant
The quote reflects the job in front of us. We take into account:
- How easy the joints are to reach
- How much old sealant there is and how hard it is to remove
- The type of sealant required
- The amount of work
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.
What to tell us for a quote
To help us quote quickly, let us know:
- The rough size of the job
- What the problem is, such as mould, gaps, leaks or cracking
- Whether it’s a home or a business
- Access, such as stairs, a lift or height
Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. Photos by email help us understand the job, and we will take it from there.
Why act early in Bac
Paying for fire stopping that has to be redone is a false economy. Work that does not follow the tested detail may have to come out again once someone inspects it. In a place like Bac, 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’ll go through it with you.
What you get with us

When to call us in Bac
Buildings are refitted and reconfigured over the years. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.
Any of these means the joints need attention:
- Open holes round services passing through fire walls
- Door frames with gaps between frame and wall
- Sealant items on a fire risk assessment action list
- Cracked or shrunken fire-rated sealant
Around Bac, as everywhere, fire rated sealant is only as good as the preparation behind it.
