How we handle fire rated sealant in Upper Sanday
Until it’s heated, intumescent sealant behaves like an ordinary sealant; in a fire it expands into the joint. The right product depends on the gap size, the substrate and what passes through, so we work to the manufacturer’s details. We work on flats & HMOs, plasterboard & masonry and door frames, and people most often call us about ordinary sealant used where a fire-rated product was needed and linear gaps at the head of walls.
Work in a place like Upper Sanday is planned ahead, journey included, so the job can fit around guests, residents or opening hours where possible.
All our work comes with our 12-month guarantee.

Upper Sanday questions
Do you cover smaller places like Upper Sanday?
Yes. Upper Sanday is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole 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.
Is Upper Sanday in your area for fire rated sealant?
Yes, Upper Sanday is within the area we cover. We work across all of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear quote.
Do you certify the fire stopping?
Ratings and certification sit with the product’s test evidence and whoever specified the work. Our part is installing the specified product to its tested details and list the locations and products for you.
I rent my home. Can I book you?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
Do you provide details of the products used?
Yes. Every gap we seal is listed with the product used, so you have it on file.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
Is standard sealant good enough for a fire gap?
No. It might close the gap, but it is not a fire-rated seal. A tested fire-rated product is needed, or ask us to do it.
What does intumescent mean?
An intumescent sealant expands when it gets hot to help seal the gap. Intumescent sealants are one kind of fire-rated sealant; the right one depends on the gap and what passes through it.
Why act early in Upper Sanday
A quick fill with any sealant to hand isn’t fire stopping. A fire-rated product only performs as tested when it’s installed to its tested detail, which is why we match the product and the method to each gap. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Surface by surface
Linear gaps
Gaps along the top of partitions are easy to miss above a ceiling. We work along the whole run so there are no open sections left.
Masonry and concrete
Core-drilled and broken-out holes in concrete are often irregular. We check the gap size around the service against the product’s tested range.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Get damaged fire seals looked at promptly
- Do not fill fire-stopping gaps with ordinary foam or silicone
- Don’t paint over fire sealant until it has cured
- Plan fire stopping into any work that goes through walls or floors
Leave the sealant to cure fully before painting near it. Not every fire-rated sealant takes paint.
It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole and the job gets bigger.
Honest limits
Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:
- Issuing a fire rating or certificate for a building
- Fire risk assessments, which need a qualified assessor
- Openings too large for sealant, which need batts, boards or another system
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think.
