Fire rated sealant in Castlebay
Fire stopping only performs as intended if it’s done to the detail: the right depth, the right backing and the right product for the substrate. That is the part we focus on, one gap at a time. If you’re dealing with gaps filled with a product that isn’t fire-rated and gaps around pipes and cables through fire-resisting walls, we can help.
For a place like Castlebay, the journey and timings are planned in advance, so the job can fit around guests, residents or opening hours where possible.

Why it’s worth doing now in Castlebay
Fire-rated sealants need more care than everyday sealant. How it’s installed changes how it performs, so we follow the maker’s details on every gap. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote.

What the job involves on each surface
Service penetrations
Service penetrations are where new gaps often appear. We clean out what’s there and reseal to the right depth over any backing the detail calls for.
Linear gaps
Some linear gaps have to cope with movement as well as fire. We choose a product and depth that suit the gap and the movement, following the tested detail.
Fire rated sealant around Castlebay
If you run a hotel, guest house or holiday let in a coastal place like Castlebay, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. Work on the islands has to be planned around ferry crossings and the weather, so the more notice, the better.
For site and facilities teams at buildings such as Castlebay Community School, service openings in fire-resisting walls need checking after any refurbishment. For buildings such as Church of our Lady, service openings in its walls need the right fire-rated sealant, as in any building.

Can I do it myself?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
What we do, step by step
We keep the work tidy and contained to the joints we’re treating, so you can get on with your day. The job normally takes from a few hours to a few days, depending on the number of gaps and the access, and we explain the cure time before we leave. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- 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.
- 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.
- Finally, we list where we worked and what we used, for your records.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Tell us if parking is tricky
- Mention any leaks or damp you’ve noticed

Advice
Your questions about fire rated sealant in Castlebay
Do you cover Castlebay for fire rated sealant?
Yes, Castlebay is within the area we cover. Our work covers the whole of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we will give you a clear quote.
Are the rules for fire-rated sealant different in Scotland?
Building work in Scotland comes under the Building (Scotland) Regulations and their 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?
Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent ones swell in heat, and they’re one option among several. The specification and the tested detail decide which is used.
Are you fully insured?
Yes. We’re fully insured.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
What fire rating will the seal have?
We do not issue ratings or certificates ourselves. The performance comes from the product’s tested details and the specification from your assessor or designer.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit.
Can I use normal mastic around a pipe through a fire wall?
No. It might close the gap, but it is not a fire-rated seal. Use a product tested for that gap and service and we can apply it for you.
