Surface by surface
Masonry and concrete
For masonry and concrete, we use a product tested in that substrate. The gap is cleaned of dust first so the seal has something sound to bond to.
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.
About our fire rated sealant in Portvoller
Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. Each gap is sealed to the product maker’s tested detail for its size and substrate, and we can record what went where. We work on pipe & cable gaps, plasterboard & masonry and door frames, and the jobs we see most are open gaps behind door architraves and cracked or shrunken fire-rated sealant.
Commercial work around smaller Scottish places tends to mean hotels, guest houses, schools and halls rather than offices. Each needs sound sealant in its washrooms and kitchens, and fire-rated joints kept in good order.
We stand behind the work with a one-year guarantee, so you are covered after we’ve gone.

What else we do in Portvoller
Portvoller: your questions answered
Is Portvoller within the area you cover?
Yes, Portvoller is covered. We work across all of Scotland, islands included, and smaller places are part of that. Longer journeys are simply planned in advance.
How do Scotland’s building regulations apply to fire-rated sealant in Portvoller?
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 do not certify buildings or do fire risk assessments; your assessor or building control can tell you what’s required.
How long does fire rated sealant take?
As a guide, most jobs take a few hours for a handful of gaps, and longer for a whole building. Bigger jobs take longer.
Can you tell me how many minutes the seal will last?
We do not certify fire stopping or quote ratings. We apply the specified product to the manufacturer’s details and giving you a record of where it went.
What does fire rated sealant cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before any work starts.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Is intumescent sealant the same as fire-rated sealant?
An intumescent sealant expands when it gets hot, helping close the gap. Intumescent sealants are one kind of fire-rated sealant; the right one depends on the gap and what passes through it.
Is there a guarantee?
Yes, always. Each job is guaranteed for twelve months.
When it isn’t the sealant
New sealant cannot fix everything, and we will tell you before any work starts. Sealant won’t put right:
- Doors that are not fire doors in the first place
- Construction that doesn’t provide fire resistance on its own
- Assessing a building’s fire safety
If you are not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer before booking.

Leave it or put it right?
An open gap in a fire-resisting wall is a route for smoke and fire. A proper seal lets the wall do its job again, and the work involved is often modest. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
The cost depends on the amount of work, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start.

- Gaps where walls meet ceilings or slabs
- New service routes left unsealed after building work
- Standard silicone or caulk in a fire-stopping gap
- Joints picked up in a fire-stopping survey
