Fire rated sealant for homes and businesses in Crawfordjohn
A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. We check the size and the substrate before choosing the product, then apply it to the depth its tested detail calls for. If you have new service routes left unsealed after building work and standard silicone or caulk in a fire-stopping gap, we can put it right, on linear gaps, pipe & cable gaps and service penetrations alike.
For a place like Crawfordjohn, the journey and timings are planned in advance, so the job can fit around guests, residents or opening hours where possible.
Whatever the size of the job, you get the same one-year guarantee.

Fire rated sealant around Crawfordjohn
Scotland has its own building regulations, the Building (Scotland) Regulations, with technical handbooks. Fire-rated sealant is installed to the manufacturer’s tested details; we do not certify buildings or carry out fire risk assessments.
Around Crawfordjohn, as everywhere, fire rated sealant is only as good as the preparation behind it. If you look after a church, hall or community building such as Crawfordjohn Parish Church, service openings in its walls need the right fire-rated sealant, as in any building.

Crawfordjohn: your questions answered
Is Crawfordjohn in your area for fire rated sealant?
Yes. We work across all of Scotland, and Crawfordjohn is part of that. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing.
Do Scottish building rules affect fire-rated sealant work in Crawfordjohn?
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 do fire risk assessments; your assessor or building control can tell you what’s required.
Is standard sealant good enough for a fire gap?
No. Where a fire-rated seal is needed, it has to be a product tested for that use.
Do I need to be at home?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Do you certify the fire stopping?
We don’t give ratings or certificates for our work. The requirement comes from your assessor, designer or building control, and we fit a product whose tested details meet it, recording the locations and products.
I rent my home. Can I book you?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
Is intumescent sealant the same as fire-rated sealant?
Intumescent describes a material that swells in heat. Many fire-rated sealants work this way, but not all.
What happens on the day
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to several days, depending on how many gaps there are. Outdoor work around Crawfordjohn depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- Old or unsuitable sealant is cut out and the gap cleaned.
- We put in whatever backing or fill the product detail specifies.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Finally, we list where we worked and what we used, for your records.
Before we arrive
- Let us know about earlier repairs to the joints
- Tell us if parking is tricky
- Clear the area around the work

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.
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.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Include hidden areas like risers in routine checks
- Ask every contractor to reseal any fire stopping they disturb
- Report cracked or damaged seals as soon as you notice them
- Include fire stopping when you schedule refits
Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some cannot, so ask us which we used.
Any job that breaks through a wall or ceiling should include resealing. Doing it at the time avoids leaving gaps behind.
What we can’t put right
Some problems need a builder, plumber or other trade rather than us:
- Fire risk assessments, which need a qualified assessor
- Problems with the door itself rather than the gap around the frame
- Certifying a building or signing off its fire safety
If you are not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer.

Why it’s worth doing now in Crawfordjohn
An unsealed gap lets smoke and fire get round a wall that was built to hold them back. Sealing it properly restores what the wall was there to do, and the work involved is often modest. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
What you get with us
- 4.9 on Google from 180+ five-star reviews
- Sanitary silicone with an anti-fungal additive in wet areas
- ARBOMaster approved applicator
- We’re fully insured
What affects the cost of fire rated sealant
We quote each job individually. This is what makes a difference:
- The product the joint needs
- Any mould that needs treating
- Whether the work is at height
- Working hours on commercial sites
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first.
Asking for a quote
To help us quote quickly, let us know:
- Access, such as stairs, a lift or height
- How many joints, rooms or windows are involved
- The type of property
- What’s wrong with the joints now
We quote each job on its own. Simply drop us a line at info@mrmastic.co.uk and describe the job.
