Grindiscol Fire Rated Sealant
Our applicators work in Grindiscol on intumescent and fire-rated sealant around gaps, frames and service penetrations. Old material cut out, joints cleaned and sealed neatly.
- Linear gaps at the head of walls
- Unsealed gaps where pipes and cables go through a wall
- Old fire sealant that has split or come away
Keeping the joints in good condition
After the cure time, these simple habits help:
- Tell trades working in the building that fire seals must be put back
- Plan fire stopping into any work that goes through walls or floors
- Don’t paint over fire sealant until it has cured
- Report cracked or damaged seals as soon as you notice them
Tell other trades that the gaps have been sealed, and ask them to reseal anything they cut through. Later work is a common cause of damaged fire stopping.
An open gap is not only a fire issue: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.
Fire rated sealant for homes and businesses in Grindiscol
Filling a fire-stopping gap with standard silicone or caulk doesn’t make it fire-rated. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. We work on linear gaps, service penetrations and flats & HMOs, and people most often call us about standard silicone or caulk in a fire-stopping gap and open holes round services passing through fire walls.
If you look after holiday lets, a guest house or a community building in or near Grindiscol, the washrooms and kitchens need the same care as any city building, and fire-rated joints should be kept in good order.
Every job comes with our one-year guarantee, wherever you are in the Shetland Islands.

What sealant work can’t fix
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Fire doors that need new seals, closers or hardware
- 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
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think.
Surfaces we seal
- Linear gaps
- Plasterboard & masonry
- Pipe & cable gaps

When to call us in Grindiscol
Movement in the structure can open gaps too: a seal that cracks or pulls away leaves a path for smoke. Damage from cleaning, knocks and maintenance adds to it.
Most people get in touch after spotting something like this:
- Seals cut through by electricians, plumbers or data installers
- Fire seals that have cracked with movement
- Gaps around pipes and cables through fire-resisting walls
- Open joints along the top of partitions
For buildings such as Bressay Kirk, service openings in its walls need the right fire-rated sealant, as in any building.

How it works
We work through the job in order: protect, prepare, seal, tidy. Typically it takes from a few hours to a few days, depending on the number of gaps and the access. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- 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.
- Unsuitable material such as ordinary foam or silicone is cut out and the gap 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.
Getting ready for the visit
- Keep children and pets away from the work area
- Mention any leaks or damp you’ve noticed
- Tell us if parking is tricky

Surface by surface
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.
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.
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Your questions about fire rated sealant in Grindiscol
Is Grindiscol within the area you cover?
Yes. Grindiscol is within the area we cover, which takes in towns, villages and rural addresses. 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.
How do Scotland’s building regulations apply to fire-rated sealant in Grindiscol?
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 do not certify buildings or do fire risk assessments; your assessor or building control can tell you what’s required.
Can you work in occupied buildings?
Yes. We work in flats, HMOs, schools, offices and other commercial buildings, including occupied ones. The order of work and access are planned with you.
Do you offer different sealant colours?
Usually, yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before any work starts.
Is the work guaranteed?
Yes, for a year. If anything is not right with the work within the year, let us know and we will sort it.
Do the sealants smell?
Possibly a little. It fades as the sealant cures.
Do you have insurance?
Yes. We’re fully insured.
Can you do several jobs on one visit?
Yes. More than one area can go on one quote.
What fire rated sealant looks like in Grindiscol

There are hotels and other places to stay in and around Grindiscol. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.
