Fire rated sealant in Na h-Eileanan an Iar, done properly
Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. Anything unsuitable comes out first and reseal with a fire-rated product tested for that kind of gap. If you are dealing with open gaps behind door architraves and ordinary sealant used where a fire-rated product was needed, we can put it right.
If you look after holiday lets, a guest house or a community building in or near Na h-Eileanan an Iar, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
Big or small, you get the same 12-month guarantee in Na h-Eileanan an Iar and across Na h-Eileanan Siar.

Why it’s worth doing now in Na h-Eileanan an Iar
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 is not suitable for sealant, we will tell you. 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.
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.

Work for landlords, hotels and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
What we can’t put right
To be straight with you, there are a few things sealant will not fix:
- Sign-off of the building, which sits with building control or your assessor
- Deciding what fire stopping a building needs
- Construction that doesn’t provide fire resistance on its own
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly.
Surfaces we seal
- Flats & HMOs

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Common questions in Na h-Eileanan an Iar
Can you do fire rated sealant in Na h-Eileanan an Iar?
Yes. Our work covers the whole of Scotland, and Na h-Eileanan an Iar is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear price.
How do Scotland’s building regulations apply to fire-rated sealant in Na h-Eileanan an Iar?
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 don’t certify buildings or carry out fire risk assessments, so your fire risk assessor or building control will advise on what’s needed.
Can you tell me how many minutes the seal will last?
We do not 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.
Do you remove the old sealant?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
I rent my home. Can I book you?
Yes. Check with your landlord; we can send the quote to them too.
What does intumescent mean?
Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent ones swell in heat, and they’re one of the options. The specification and the tested detail decide which is used.
Can ordinary silicone be used in a fire-stopping gap?
No. It looks sealed but will not perform as fire stopping. Use a product tested for that gap and service and we can apply it for you.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
