How we handle fire rated sealant in Dundrennan
Landlords, managing agents and facilities teams use us for the sealant items on a fire risk assessment on buildings across Dundrennan. Send us the list or the survey and we will quote for the fire-rated sealant work on it. We work on linear gaps, door frames and plasterboard & masonry, and people most often call us about open gaps behind door architraves and seals cut through by electricians, plumbers or data installers.
In a smaller place like Dundrennan, commercial jobs are more likely to be a hotel, guest house, school, surgery or community hall than an office block. Each needs sound sealant in its washrooms and kitchens, and fire-rated joints kept in good order.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

The process
The work is kept neat and contained to the area we’re working on, so you can carry on as normal. The job usually takes anything from a few hours to several days, depending on how many gaps there are, and we explain the cure time before we leave. Outdoor work around Dundrennan depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- Old or unsuitable sealant is cut out and the gap cleaned.
- Where the tested detail needs backing or fill, we fit it.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- Locations and products are noted so you have them on file.
Preparing for the visit
- Tell us if parking is tricky
- Let us know if you’ve seen damp or leaks
- Where the joints are inside, avoid wetting them before we arrive

Advice
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What sealant work cannot fix
A few problems are outside what sealant work can do:
- Big openings where sealant alone isn’t the tested solution
- Sign-off of the building, which sits with building control or your assessor
- A wall that is not a fire-resisting element to begin with
If you’re not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer before booking.

When to call us in Dundrennan
Over time, buildings change layout and use. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.
These are the problems we are asked about most:
- Fire seals that have cracked with movement
- Door frames with gaps between frame and wall
- Holes left by a change of layout
- Fire stopping disturbed by later work
Community buildings like Dundrennan Parish Church are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

Workplaces and buildings in Dundrennan
If you run a hotel, guest house or holiday let in a coastal place like Dundrennan, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. Scotland has its own building regulations, the Building (Scotland) Regulations, with technical handbooks. We install fire-rated sealant to the product’s tested details; we don’t certify buildings or carry out fire risk assessments.
In and around Dundrennan, as anywhere, good fire rated sealant starts with a clean, dry, properly prepared joint.

Dundrennan questions
Is Dundrennan 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.
Are the rules for fire-rated sealant different in Scotland?
Building work in Scotland comes under the Building (Scotland) Regulations and their 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 don’t certify buildings or do fire risk assessments; your assessor or building control can tell you what’s required.
What does fire rated sealant cost?
It depends on the job, so we quote each one individually. For a quick quote, email us at info@mrmastic.co.uk with a short description of the job.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Do you provide details of the products used?
Yes. You get a list of where we worked and what we used for your files.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Why deal with it now?
Waiting for the next refit can leave a gap open for years. On its own, sealing it now is a small job. In a place like Dundrennan, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
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.
