Cuidhir Fire Rated Sealant
Intumescent and fire-rated sealant around gaps, frames and service penetrations for homeowners, landlords and businesses in Cuidhir. ARBOMaster approved applicators, fully insured, with a 12-month guarantee.
- Gaps left after a refit or conversion
- Linear gaps at the head of walls
- Fire stopping disturbed by later work
What happens if it’s left?
For some gaps, sealant isn’t the right answer and another system is needed. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. If a gap is not suitable for sealant, we will tell you. In an older home around Cuidhir, damp from a failed joint can get into timber and plaster.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Fire rated sealant in Cuidhir
We can work through a building room by room or floor by floor, with each location and product recorded. That record is useful for your files and for whoever looks at the building next. We’re often asked to deal with gaps around pipes and cables through fire-resisting walls and seals cut through by electricians, plumbers or data installers, on door frames, plasterboard & masonry and service penetrations.
Commercial work around smaller Scottish places tends to mean hotels, guest houses, schools and halls rather than offices. All of them have washrooms, kitchens and fire-rated joints that need looking after.
Our work is backed for twelve months, in Cuidhir and everywhere else we cover.

What we’re called out for in Cuidhir
Much fire stopping is hidden: above ceilings, inside risers and behind panels. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.
Most people get in touch when they notice something like this:
- Damaged fire sealant left by other trades
- Open holes round services passing through fire walls
- Gaps where walls meet ceilings or slabs
- Standard silicone or caulk in a fire-stopping gap
For buildings such as Cuier Parish Church and Churchyard, service openings in its walls need the right fire-rated sealant, as in any building.
What to look for in a quote
- Is the old sealant removed completely?
- How much experience the applicator has

- What happens if the job turns out different
The process
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes from a few hours to a few days, depending on the number of gaps and the access. Around Cuidhir, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Old or unsuitable sealant is cut out and the gap cleaned.
- We put in whatever backing or fill the product detail specifies.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- Finally, we list where we worked and what we used, for your records.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Move anything stored near the joints
- Keep children and pets away from the work area

Advice
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Plan fire stopping into any work that goes through walls or floors
- Tell trades working in the building that fire seals must be put back
- File the fire-stopping record where your assessor can find it
- Take pictures of fire stopping before ceilings or boxing go back
Include fire stopping in your regular building checks. Look for cracks, gaps or sealant that has been cut or pulled out and have them put right.
A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded so you can show it was dealt with.

FAQs for Cuidhir
Do you cover smaller places like Cuidhir?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland, including the islands, where work is planned around ferry crossings. Let us know about access, parking and anything unusual about getting there when you book.
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 do not certify buildings or carry out fire risk assessments, so your fire risk assessor or building control will advise on what’s needed.
Is standard sealant good enough for a fire gap?
No. It might close the gap, but it isn’t a fire-rated seal. Use a product tested for that gap and service.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
How long does the job take?
Most jobs take from a few hours to a few days, depending on the number of gaps and the access, including the preparation. Your quote will say how long we expect yours to take.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
What affects the quote in Cuidhir
Your quote is based on your job. We take into account:
- Which sealant suits the joint
- Whether the work is at height
- The size of the job
- Any mould that needs treating
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
What to tell us for a quote
Before you ask for a quote, have a think about:
- Where the property is
- Roughly how big the job is
- Access, such as stairs, a lift or height
- Whether it’s a home or a business
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, send an email to info@mrmastic.co.uk.

Can I do it myself?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
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.
