What we do, step by step
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and clear up. Most jobs take anything from a few hours to several days, depending on how many gaps there are. 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.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- Each gap is measured and its substrate and service noted.
- Any non-fire-rated filler is removed and the gap cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used.
Before we arrive
- Mention if the joints have been sealed before
- Plan for the work area to be out of bounds to pets and children
- Where the joints are inside, avoid wetting them before we arrive

About our fire rated sealant in Coalburn
Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. Anything unsuitable comes out first and reseal with a fire-rated product tested for that kind of gap. If you are dealing with gaps left after a refit or conversion and seals cut through by electricians, plumbers or data installers, we can put it right, on pipe & cable gaps, door frames and service penetrations alike.
If you look after holiday lets, a guest house or a community building in or near Coalburn, the washrooms and kitchens need the same care as any city building, and fire-rated joints should be kept in good order.
There’s a 12-month guarantee on every job, whatever its size.

Landlord and commercial work in Coalburn
We work for letting agents and landlords as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
What we are called out for in Coalburn
Lots of unsealed gaps appear long after the building was completed. New cables, pipes and data runs go through walls and ceilings and the hole round the new service isn’t always sealed again.
Signs it’s time to call us include:
- Gaps filled with a product that is not fire-rated
- Linear gaps at the head of walls
- Fire seals that have cracked with movement
- Door frames with gaps between frame and wall
Around Coalburn, as everywhere, fire rated sealant is only as good as the preparation behind it.
Before booking anyone
- How the joint is cleaned and prepared
- What the quote includes, VAT included or not
- How hidden problems are handled
- When the joint can take water or movement
What affects the quote in Coalburn
The price is agreed before any work begins. It takes into account:
- How many areas need sealing
- Working hours on commercial sites
- Access and height
- The product the joint needs
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.
What we need to know
You do not need to know the technical terms. It helps if you can tell us:
- A few pictures by email, if you can
- Access, such as stairs, a lift or height
- Where the property is
- What’s wrong with the joints now
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email pictures if that is easy.

Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.

What happens if it’s left?
An open gap in a fire-resisting wall is a route for smoke and fire. Sealing it properly restores what the wall was there to do, and the sealing itself is often a contained piece of work. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, send an email to info@mrmastic.co.uk for an honest opinion and a quote.

Questions from Coalburn
Will you come out to Coalburn?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Are the rules for fire-rated sealant different in Scotland?
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 I use normal mastic around a pipe through a fire wall?
No. Standard sealants aren’t made or tested to stop fire. We cut it out and reseal with a fire-rated product.
Do you take on fire stopping in schools and offices?
Yes. We regularly work in flats, HMOs, schools and offices while they’re in use, with access planned around residents or staff. Out-of-hours work can be arranged.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can you match the sealant colour?
Most of the time, yes. We will tell you which colours the right product comes in.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Is intumescent sealant the same as fire-rated sealant?
Intumescent means it swells when heated to help seal the gap. Intumescent sealants are one kind of fire-rated sealant; which product suits depends on the gap, the substrate and the service.
Looking after it afterwards
Aftercare is simple:
- Tell trades working in the building that fire seals must be put back
- Ask which product was used before you paint
- Report cracked or damaged seals as soon as you notice them
- Check risers, ceiling voids and cupboards during building checks
Any fire seal that’s cut or drilled needs resealing to its tested detail. New services through a sealed wall should include fire stopping in the plan.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.
