What affects the quote in Arrochar
We quote each job individually. These are the things that affect it:
- Whether the work is at height
- How many rooms, windows or areas are involved
- Which sealant suits the joint
- Any mould that needs treating
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. You will know the price before we begin.
What we need to know
To help us quote quickly, let us know:
- What the problem is, such as mould, gaps, leaks or cracking
- The rough size of the job
- Where the job is, and your postcode
- A few photos by email, if you can
We don’t publish a price list, because every job is different. Instead, we send you a clear quote for your job. To get started, send an email to info@mrmastic.co.uk.
How we handle fire rated sealant in Arrochar
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. We work on service penetrations, door frames and flats & HMOs, and people most often call us about open gaps behind door architraves and sealant items on a fire risk assessment action list.
If you look after holiday lets, a guest house or a community building in or near Arrochar, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
All our work comes with a 12-month guarantee, wherever you are in West Dunbartonshire.

Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Flag any open gap you spot round a pipe or cable
- Check whether a sealant can be painted before decorating over it
- Take pictures of fire stopping before ceilings or boxing go back
- Make resealing part of every contractor’s brief
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.
A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded so the item can be closed.
What we can’t put right
In fairness, there are a few things sealant will not fix:
- Construction that does not provide fire resistance on its own
- Big openings where sealant alone is not the tested solution
- Problems with the door itself rather than the gap around the frame
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly.
What we seal
- Door frames
- Linear gaps
- Service penetrations
- Plasterboard & masonry
- Pipe & cable gaps
- Flats & HMOs
Leave it or put it right?
Items left open on a fire risk assessment tend to come back at the next review. Getting them done and written up gives you evidence that the item was dealt with. 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.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll explain what it covers.

When to call us in Arrochar
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.
Signs it’s time to call us include:
- Standard silicone or caulk in a fire-stopping gap
- Cracked or shrunken fire-rated sealant
- Holes left by a change of layout
- Open holes round services passing through fire walls
If you let a flat or house near Arrochar & Tarbet station, any gap left by new services in shared walls should be closed with a fire-rated product.
What your quote should include
- Who turns up on the day
- Is VAT in the price?
- How the surfaces are prepared before sealing
- What product goes in the joint
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Arrochar questions
Are the rules for fire-rated sealant different in Scotland?
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’s how we fit it. We do not certify buildings or carry out fire risk assessments, so your fire risk assessor or building control will advise on what’s needed.
Is Arrochar within the area you cover?
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.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Do you work in flats, HMOs and commercial buildings?
Yes. Flats, HMOs, offices, schools and other occupied buildings are all part of our work. We agree access and the order of work with you first.
Is standard sealant good enough for a fire gap?
No. Standard sealants aren’t made or tested to stop fire. We cut it out and reseal with a fire-rated product.
Can new sealant go over the old?
No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
How do I get a quote for fire rated sealant in Arrochar?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.
