Fire-rated sealant in Charlestown, Highland
We cover Charlestown for intumescent and fire-rated sealant around gaps, frames and service penetrations. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Seals cut through by electricians, plumbers or data installers
- Open joints along the top of partitions
- Gaps flagged on a fire risk assessment
How the visit works
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take from a few hours to a few days, depending on the number of gaps and the access. For a place like Charlestown, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- Before starting, we go through the specification or action list with you.
- Each gap is measured and its substrate and service noted.
- Unsuitable material such as ordinary foam or silicone is cut out.
- We fit backing where needed and apply the fire-rated sealant to depth.
- We hand over a list of locations and products for your records.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Mention if the joints have been sealed before
- Mention any tricky access

Fire rated sealant in Charlestown
Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. Each gap is sealed to the product maker’s tested detail for its size and substrate. We are often asked to deal with ordinary sealant used where a fire-rated product was needed and unsealed gaps where pipes and cables go through a wall, on plasterboard & masonry, service penetrations and linear gaps.
If you look after holiday lets, a guest house or a community building in or near Charlestown, the washrooms and kitchens need the same care as any city building, and fire-rated joints should be kept in good order.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

DIY versus a professional 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, and the work is guaranteed for a year.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

When something else is needed
We will not take on work that won’t last, so these are the limits:
- Construction that doesn’t provide fire resistance on its own
- Sign-off of the building, which sits with building control or your assessor
- Assessing a building’s fire safety
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly before booking.

Signs you need fire rated sealant in Charlestown
Sealant applied too thin, without the backing its detail needs, or onto dust won’t perform as it was tested. We see plenty of fire stopping that was hurried particularly when it was the last job before handover.
Keep an eye out for any of the following:
- Holes left by a change of layout
- Old fire sealant that has split or come away
- Linear gaps at the head of walls
- Joints picked up in a fire-stopping survey
Letting a property close to Inverness station? Then any gap left by new services in shared walls should be closed with a fire-rated product.

What fire rated sealant looks like in Charlestown
For seaside hotels, guest houses and holiday lets around Charlestown, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. Scotland has its own building regulations, the Building (Scotland) Regulations, with technical handbooks. We install fire-rated sealant to the product’s tested details, though we don’t certify buildings or do fire risk assessments.
For site and facilities teams at buildings such as Inverness High School, service openings in fire-resisting walls need checking after any refurbishment.

FAQs for Charlestown
Is Charlestown within the area you cover?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
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. Whatever the rules, fire-rated sealant has to be installed to the manufacturer’s tested details, and that’s 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.
Do you provide details of the products used?
Yes. Locations and products are written up when we finish. If you need pictures or a set layout, ask when you get a quote.
How long does fire rated sealant take?
Most jobs take anything from a few hours to several days, depending on how many gaps there are. Your quote will say how long we expect yours to take.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first.
How much does fire rated sealant cost in Charlestown?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
Is the work guaranteed?
Yes. Each job is guaranteed for twelve months.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Plan fire stopping into any work that goes through walls or floors
- Keep the record of products and locations with your fire safety documents
- Get damaged fire seals looked at promptly
- 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.
What happens if it’s left?
Leaving a gap until a refurbishment comes round can mean years with it open. Sealing the gap now is a contained job on its own that does not depend on other work. Around Charlestown, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first.
