Common problems we fix in Grimsay
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.
Look out for any of the following:
- Seals cut through by electricians, plumbers or data installers
- Gaps left after a refit or conversion
- Cracked or shrunken fire-rated sealant
- Standard silicone or caulk in a fire-stopping gap
In and around Grimsay, as anywhere, good fire rated sealant starts with a clean, dry, properly prepared joint.

Fire rated sealant in Grimsay
We do not assess buildings or decide what fire stopping is needed; your assessor, designer or building control sets that out. What we do is apply the right product to that specification, properly and neatly. We work on linear gaps, door frames and plasterboard & masonry, and people most often call us about holes left by a change of layout and fire stopping disturbed by later work.
For a place like Grimsay, the journey and timings are planned in advance, so it can be fitted around bookings or opening times where possible.
There’s a 12-month guarantee on every job, whatever its size.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
FAQs for Grimsay
Do Scottish building rules affect fire-rated sealant work in Grimsay?
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 do not certify buildings or do fire risk assessments; your assessor or building control can tell you what’s required.
Can you do fire rated sealant in Grimsay?
Yes, Grimsay is within the area we cover. Our work covers the whole of Scotland. You can send an email to info@mrmastic.co.uk and tell us what needs doing, and we will give you a clear price.
Are you insured?
Yes, we’re fully insured.
Where are you based?
We work from Crawley. We cover Grimsay and the rest of Na h-Eileanan Siar.
Do you do fire sealant around door frames?
Yes. We seal the gap between the frame and the wall with a suitable fire-rated product. The door leaf and its hardware need a door specialist.
Do you guarantee your work?
Yes. Every job comes with our one-year guarantee.
Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
How to look after the new joints
Aftercare is simple:
- Keep the record of products and locations with your fire safety documents
- Plan fire stopping into any work that goes through walls or floors
- Keep pictures of seals that will be hidden
- Check risers, ceiling voids and cupboards during building checks
Any fire seal that is cut or drilled needs resealing to its tested detail. New services through a sealed wall should include fire stopping in the plan.
An open gap is not only a fire issue: noise, draughts and even pests can come through too. Sealing them early helps on every front.
What else we do in Grimsay
Why it’s worth doing now in Grimsay
Items left open on a fire risk assessment tend to come back at the next review. Getting them done and written up gives you evidence that the item was dealt with. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

How the visit works
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the job takes anything from a few hours to several days, depending on how many gaps there are in most cases. Outside jobs in Grimsay need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- Before starting, we go through the specification or action list with you.
- We measure every gap and note what it’s in and what passes through.
- Any non-fire-rated filler is removed.
- The specified fire-rated sealant goes in over any backing its detail requires.
- We hand over a list of locations and products for your files.
Preparing for the visit
- Clear the area around the work
- Mention any leaks or damp you’ve noticed
- Mention any parking rules near the property

When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Construction that doesn’t provide fire resistance on its own
- Large holes that need a different fire-stopping system
- Problems with the door itself rather than the gap around the frame
