Upper Coll Fire Rated Sealant
Our applicators work in Upper Coll on intumescent and fire-rated sealant around gaps, frames and service penetrations. Old sealant removed completely, joints prepared properly.
- Gaps filled with a product that is not fire-rated
- Gaps where walls meet ceilings or slabs
- Unsealed gaps where pipes and cables go through a wall
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Fire rated sealant in Upper Coll
We can work through a building room by room or floor by floor, noting the locations and products as we go. It gives you a list to keep with the building’s fire safety documents. We work on linear gaps, pipe & cable gaps and door frames, and the jobs we see most are gaps filled with a product that isn’t fire-rated and linear gaps at the head of walls.
If you look after holiday lets, a guest house or a community building in or near Upper Coll, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
We stand behind the work with a one-year guarantee.

What happens on the day
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a handful of gaps, and longer for a whole building. Around Upper Coll, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- Old or unsuitable sealant is cut out and the gap cleaned.
- Backing or fill is fitted where the product’s tested detail calls for it.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- Locations and products are noted so you have them on file.
Preparing for the visit
- Move anything stored near the joints
- Mention any leaks or damp you’ve noticed
- Mention any sign-in or site rules at work premises

Advice
Common problems we fix in Upper Coll
Gaps also open up as buildings move: a seal that cracks or pulls away leaves a path for smoke. Knocks, maintenance and building work damage it further.
If you can see any of these, it’s time to have the joints looked at:
- Open gaps behind door architraves
- Gaps around pipes and cables through fire-resisting walls
- Joints picked up in a fire-stopping survey
- Cracked or shrunken fire-rated sealant
In and around Upper Coll, as anywhere, good fire rated sealant starts with a clean, dry, properly prepared joint.

Questions from Upper Coll
Will you come out to Upper Coll?
Yes, we do. We work across all of Scotland, islands included, and smaller places are part of that. Longer journeys are simply planned in advance.
Are the rules for fire-rated sealant different in Scotland?
Scotland has its own building regulations, the Building (Scotland) Regulations, with their own technical handbooks. Fire-rated sealant has to go in to the product’s tested details, and we follow them. We don’t certify buildings or do fire risk assessments; your assessor or building control can tell you what’s required.
Is intumescent sealant the same as fire-rated sealant?
Intumescent means it swells when heated to help seal the gap. Intumescent sealants are one kind of fire-rated sealant; the right one depends on the gap and what passes through it.
Where is Mr Mastic based?
Our base is Crawley. We work across South East England, London and Scotland.
Do you take on fire stopping in schools and offices?
Yes. Occupied flats, HMOs, offices and schools are all fine, with access planned around residents or staff. Out-of-hours work can be arranged if that suits the building.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first, so the new sealant bonds properly.
Will you assess my building’s fire safety?
No. We work from the specification you give us and install to the manufacturer’s details.
How long does fire rated sealant take?
That depends on how much there is to do, but most jobs take from a few hours to a few days, depending on the number of gaps and the access. We’ll give you a better idea when we quote.
Different surfaces, different methods
Plasterboard walls
Many fire-resisting walls in flats, offices and conversions are plasterboard. We use a product tested in that kind of wall for the gap we’re sealing.
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.

Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Report cracked or damaged seals as soon as you notice them
- Don’t paint over fire sealant until it has cured
- Ask every contractor to reseal any fire stopping they disturb
- Plan fire stopping into any work that goes through walls or floors
Leave the sealant to cure fully before painting near it. Some fire-rated sealants can be painted and some can’t, so ask us which we used.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Sealing it early is a simple step to take.
