Fire rated sealant in Westruther
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. If you have seals cut through by electricians, plumbers or data installers and gaps left after a refit or conversion, we can put it right, whatever the surface.
Work in a place like Westruther is planned ahead, journey included, so it can be fitted around bookings or opening times where possible.
Every job is covered by our one-year guarantee.

Leave it or put it right?
Fire-rated sealants need more care than everyday sealant. Depth, backing and surface preparation all affect how a seal performs, so we follow the maker’s details on every gap. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will go through it with you.

Fire rated sealant in Westruther: local notes
In Scotland, building work comes under the Building (Scotland) Regulations and their technical handbooks. We install fire-rated sealant to the product’s tested details, though we do not certify buildings or do fire risk assessments.
Around Westruther, as everywhere, fire rated sealant is only as good as the preparation behind it. Community buildings like Old Parish Church and Churchyard are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

Surface by surface
Service penetrations
Service penetrations are where new gaps often appear. Old or unsuitable filler comes out before the right sealant goes in with backing where the detail needs it.
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.
What sealant work can’t fix
Some problems need a builder, plumber or other trade rather than us:
- Issuing a fire rating or certificate for a building
- Openings too large for sealant, which need batts, boards or another system
- A wall that isn’t a fire-resisting element to begin with
If you are not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer.

Your questions about fire rated sealant in Westruther
Is Westruther within the area you cover?
Yes. Westruther is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
How do Scotland’s building regulations apply to fire-rated sealant in Westruther?
Scotland has its own building regulations, the Building (Scotland) Regulations, with their own technical handbooks. Whatever the rules, fire-rated sealant has to be installed to the manufacturer’s tested details, and that is how we fit it. We do not certify buildings or do fire risk assessments; your assessor or building control can tell you what’s required.
How long does the job take?
Typically it takes a few hours for a handful of gaps, and longer for a whole building. Larger jobs naturally take longer.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
Do the sealants smell?
Possibly a little. It fades as the sealant cures.
Is there a guarantee?
Yes, always. Each job is guaranteed for twelve months, wherever you are.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Plan fire stopping into any work that goes through walls or floors
- Never patch a fire seal with standard sealant
- Check risers, ceiling voids and cupboards during building checks
- Report cracked or damaged seals as soon as you notice them
Keep the record we give you with the building’s fire safety documents. It saves time at the next inspection or assessment.
An open gap is not only a fire issue: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.
What happens on the day
We bring everything the job needs with us, so you do not need to buy or prepare anything. Once we have agreed what’s being done, we protect the area and start. It normally takes a few hours for a handful of gaps, and longer for a whole building. 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.
- Access to each area is agreed so the work can run in order.
- We take out any damaged or unsuitable sealant.
- Gaps are cleaned of dust and loose material.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- We record what was done and flag anything that needs a different system.
Getting ready for the visit

- Mention any sign-in or site rules at work premises

What affects the cost of fire rated sealant
Some jobs are bigger than they look, and some smaller. The main factors:
- The number and length of the joints
- How many areas need sealing
- How much old sealant there is and how hard it is to remove
- The product the joint needs
Combining jobs into one visit is usually more efficient than separate visits. We’ll give you a clear quote for the lot.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- Whether it has been sealed before
- Where the job is, and your postcode
- How many joints, rooms or windows are involved
- If it’s domestic, commercial or a hotel
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job.
Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
