About our fire rated sealant in Cairston
Until it’s heated, intumescent sealant behaves like an ordinary sealant; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through, so we work to the manufacturer’s details. If you are dealing with gaps where walls meet ceilings or slabs and holes left by a change of layout, we can help.
Work in a place like Cairston is planned ahead, journey included, so the job can fit around guests, residents or opening hours where possible.
You’re covered for a year from the day we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

Work for landlords, hotels and businesses
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Common questions in Cairston
Do you cover smaller places like Cairston?
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?
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’s how we fit it. 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.
Will you assess my building’s fire safety?
No. That’s for a fire risk assessor, designer or building control. Our job is applying the sealant to their specification.
Do you have insurance?
Yes, we’re fully insured.
Do you provide details of the products used?
Yes. We record the locations we have sealed and the products used for your files.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Do you certify the fire stopping?
We don’t issue ratings or certificates ourselves. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves; we install to those details and record what we did.
What’s the difference between intumescent and fire-rated sealant?
An intumescent material expands when it’s heated. Intumescent sealants are a type of fire-rated sealant.
When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Issuing a fire rating or certificate for a building
- Deciding what fire stopping a building needs
- Walls or floors that weren’t built to resist fire
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.
What we seal
- Pipe & cable gaps
- Linear gaps
- Flats & HMOs
- Service penetrations
- Door frames
- Plasterboard & masonry
Different surfaces, different methods
Door frames
Our work is the joint between frame and wall. Doors, seals and closers are for a door specialist and we’ll mention anything we notice.
Service penetrations
Service penetrations are where new gaps often appear. Old or unsuitable filler comes out before the right sealant goes in with backing where the detail needs it.
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Look in service cupboards and ceiling voids from time to time
- Check whether a sealant can be painted before decorating over it
- Keep pictures of seals that will be hidden
- Flag any open gap you spot round a pipe or cable
Avoid covering a sealed gap with anything that isn’t part of the tested detail. If it needs repair, use the same type of product. We can tell you which product 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.
Why act early in Cairston
Sealant is not the fix for every opening. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. If a gap isn’t suitable for sealant, we will tell you. Around Cairston, water from a failed joint in an older stone home can soak into timber and plaster.
Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.
Why book with us
- An ARBOMaster approved applicator
- Domestic, commercial and hotel work
- Old sealant always removed completely
- Arbo and Everbuild products

Common problems we fix in Cairston
Lots of unsealed gaps appear long after the building was completed. Electricians, plumbers and data installers drill through walls and ceilings and the hole round the new service isn’t always sealed again.
Any of these means the joints need attention:
- Linear gaps at the head of walls
- Fire seals that have cracked with movement
- Gaps flagged on a fire risk assessment
- Holes left by a change of layout
For site and facilities teams at buildings such as stromness primary school, fire-stopping around service openings should be restored whenever new services go in.
Questions to ask before you book
- Whether the sealant suits the joint
- How hidden problems are handled
- When the joint can take water or movement
- Is VAT in the price?
What happens on the day
The work is kept neat and contained to the joints we’re treating, so you can carry on as normal. The job generally takes a few hours for a handful of gaps, and longer for a whole building. Outside jobs in Cairston need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- Access to each area is agreed so the work can run in order.
- Old, damaged or unsuitable sealant is removed.
- Dust and loose debris are cleaned from each gap.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
How to prepare
- Mention if the joints have been sealed before
- Tell us if parking is tricky
- Mention any sign-in or site rules at work premises
