Leave it or put it right?
Waiting for the next refit can leave a gap open for years. Sealing the gap now is a contained job on its own that doesn’t depend on other work. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

How we handle fire rated sealant in Carrington
Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap, and we can record what went where. We work on flats & HMOs, door frames and plasterboard & masonry, and the jobs we see most are joints picked up in a fire-stopping survey and fire stopping disturbed by later work.
Commercial work around smaller Scottish places tends to mean hotels, guest houses, schools and halls rather than offices. All of them have washrooms, kitchens and fire-rated joints that need looking after.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Common problems we fix in Carrington
Door frames are a common weak spot. The architrave hides the gap between frame and wall, so it’s easy to leave unsealed when doors are changed.
It’s worth asking for a quote if you see:
- Standard silicone or caulk in a fire-stopping gap
- New service routes left unsealed after building work
- Joints picked up in a fire-stopping survey
- Cracked or shrunken fire-rated sealant
For buildings such as Carrington Parish Church, service openings in its walls need the right fire-rated sealant, as in any building.

Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Don’t fill fire-stopping gaps with ordinary foam or silicone
- Ask which product was used before you paint
- Plan fire stopping into any work that goes through walls or floors
- Tell trades working in the building that fire seals must be put back
Avoid covering a sealed gap with anything that is not part of the tested detail. Repairs should use a matching fire-rated product. We can tell you which product we used.
A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Sealing it early is a simple step to take.
Your questions about fire rated sealant in Carrington
How do Scotland’s building regulations apply to fire-rated sealant in Carrington?
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.
Is Carrington within the area you cover?
Yes. Carrington is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
What fire rating will the seal have?
We don’t 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, and we install to them.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we are done.
Is there any odour?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Where is Mr Mastic based?
We are based in Crawley, and we work across South East England, London and Scotland.
What happens on the day
When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work starts. The work usually takes anything from a few hours to several days, depending on how many gaps there are. Somewhere like Carrington may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- 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.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about earlier repairs to the joints
- Keep pets and children clear of the area while we work

DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
What affects the cost of fire rated sealant
We don’t publish a price list. What we look at:
- Any working-time requirements on site
- The product the joint needs
- The old material and how stubborn it is
- The amount of work
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- Whether it has been sealed before
- Pictures of the joints, sent by email
- What’s wrong with the joints now
- How many joints, rooms or windows are involved
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that’s easy.
