- Gaps filled with a product that isn’t fire-rated
Fire rated sealant for homes and businesses in Clestrain
Filling a fire-stopping gap with standard silicone or caulk does not make it fire-rated. We cut out the wrong material and the gap is resealed with a product tested for that use. If you have gaps filled with a product that isn’t fire-rated and gaps left after a refit or conversion, we can put it right.
Commercial work around smaller Scottish places tends to mean hotels, guest houses, schools and halls rather than offices. Each needs sound sealant in its washrooms and kitchens, and fire-rated joints kept in good order.
You get a 12-month guarantee, the same in Clestrain as everywhere else we work.

What affects the quote in Clestrain
Every job gets its own quote. This is what makes a difference:
- Mould in or behind the old joints
- Whether old sealant or filler has to be cut out
- How easy the joints are to reach
- How many rooms, windows or areas are involved
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
What to tell us for a quote
Photos by email are helpful but not essential. Try to tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- If someone has resealed it before
- How we’d reach the joints
- Pictures of the joints, sent by email
For a quote, send an email to info@mrmastic.co.uk with the location and a short description of the problem. We will give you a clear price before any work starts.
Workplaces and buildings in Clestrain
If you run a hotel, guest house or holiday let in a coastal place like Clestrain, 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 give us as much notice as you can.
Around Clestrain, as everywhere, fire rated sealant is only as good as the preparation behind it. Whether the job is in Clestrain itself or nearby, the right material for each joint matters as much as a neat finish.

Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Check whether a sealant can be painted before decorating over it
- Report cracked or damaged seals as soon as you notice them
- File the fire-stopping record where your assessor can find it
- Take photos of fire stopping before ceilings or boxing go back
Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. Later work is a common cause of damaged fire stopping.
Small gaps around services are simple to deal with while there are only a few. Over time, more work adds more holes.
Your questions about fire rated sealant in Clestrain
Is Clestrain in your area for fire rated sealant?
Yes. We work across all of Scotland, and Clestrain is part of that. Just email us at info@mrmastic.co.uk with a few details of the job, and we will give you a clear price.
Will you come out to Clestrain?
Yes, Clestrain is covered. Our work covers the whole of Scotland, islands included, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you provide details of the products used?
Yes. We note each location and the product that went in.
What fire rating will the seal have?
We do not certify fire stopping or quote ratings. Our part is installing the specified product to its tested details and list the locations and products for you.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Do you take on fire stopping in schools and offices?
Yes, in flats, HMOs, schools, offices and other buildings, occupied or empty. Let us know the building’s hours and we will plan the work to suit.
Do you guarantee your work?
Yes, always. There’s a 12-month guarantee on every job, wherever you are.
Will you assess my building’s fire safety?
No. Your fire risk assessor, designer or building control decides that. Our job is applying the sealant to their specification.
DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The process
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to several days, depending on how many gaps there are. Somewhere like Clestrain may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- We remove any old or unsuitable filler and clean the gap.
- Where the tested detail needs backing or fill, we fit 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
- Mention any tricky access
- Let us know if you’ve seen damp or leaks
- Where the joints are inside, avoid wetting them before we arrive

Related advice
Different surfaces, different methods
Flats and HMOs
In flats and HMOs, the walls and floors between homes and common areas need sealing where services pass through. We seal the gaps your assessor has identified, flat by flat if needed.
Door frames
Frame gaps are normally hidden behind the architrave. Where it’s open, we seal it to the product’s details for that gap size so the architrave can be refitted.

We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
