About our fire rated sealant in Dunbar
Filling a fire-stopping gap with standard silicone or caulk does not make it fire-rated. We cut out the wrong material and the gap is resealed with a product tested for that use. We work on linear gaps, service penetrations and plasterboard & masonry, and people most often call us about gaps left after a refit or conversion and fire stopping disturbed by later work.
In a smaller place like Dunbar, commercial jobs are more likely to be a hotel, guest house, school, surgery or community hall than an office block. All of them have washrooms, kitchens and fire-rated joints that need looking after.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Quotes for fire rated sealant in Dunbar
The price is agreed before any work begins. It’s based on:
- The size of the job
- The product the joint needs
- Access and height
- When we can work, for business premises
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Asking for a quote
What to tell us when you ask for a quote:
- Where the job is, and your postcode
- If someone has resealed it before
- What the problem is, such as mould, gaps, leaks or cracking
- Any access issues, like height or stairs
It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. Whenever you’re ready, send an email to info@mrmastic.co.uk.
Why act early in Dunbar
Leaving a gap until a refurbishment comes round can mean years with it open. On its own, sealing it now is a small job. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
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.

How the job changes by surface
Linear gaps
Head-of-wall gaps are often hidden above suspended ceilings. We work along the whole run so there are no open sections left.
Masonry and concrete
Holes through concrete and block are rarely neat. We measure the gap at its widest point against the product’s tested range.
FAQs for Dunbar
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’s how we fit it. We don’t certify buildings or carry out fire risk assessments, so your fire risk assessor or building control will advise on what’s needed.
I let a flat near Dunbar station. Can you help?
Yes, we work for landlords and letting agents. You can send an email to info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before we start.
Do you take on fire stopping in schools and offices?
Yes, whether the building is a school, an office, flats or an HMO, and whether it’s in use or not. Tell us how the building is used and we will plan around it.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
What does intumescent mean?
Intumescent means it swells when heated. It’s one type of fire-rated sealant; which product suits depends on the gap, the substrate and the service.
Will it make a mess?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you do try it yourself, take your time over the 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.

When something else is needed
In fairness, there are a few things sealant won’t fix:
- Issuing a fire rating or certificate for a building
- A wall that isn’t a fire-resisting element to begin with
- Doors that are not fire doors in the first place
If you’re not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer.

Commercial buildings in Dunbar
If you run a hotel, guest house or holiday let in a coastal place like Dunbar, 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.
For buildings such as Abbey Church of Scotland, older buildings that have had new heating or wiring often have service gaps worth checking. If you let a flat or house near Dunbar station, any gap left by new services in shared walls should be closed with a fire-rated product.

What we do, step by step
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes from a few hours to a few days, depending on the number of gaps and the access. Outside jobs in Dunbar need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- We start with the survey or action list, checking the size and surfaces of every gap.
- 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
- Keep children and pets away from the work area
- On commercial sites, let us know about site rules
- Tell us about access, such as stairs, a lift or high-level joints
