- Joints picked up in a fire-stopping survey
- Linear gaps at the head of walls
- Ordinary sealant used where a fire-rated product was needed
What happens on the day
On the day, we start by going over the job with you. We protect the surfaces around the joints before work begins. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. Outside jobs in Forth 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 isn’t 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.
- 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.
- We record the locations and products used for your records.
Preparing for the visit
- Move anything stored near the joints
- Tell us if parking is tricky
- Let us know about earlier repairs to the joints

About our fire rated sealant in Forth
Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. A new cable run or a replaced pipe can leave an open hole behind. Those are the gaps we close, using a tested fire-rated product. We work on flats & HMOs, service penetrations and linear gaps, and common reasons people get in touch are open joints along the top of partitions and unsealed gaps where pipes and cables go through a wall.
Commercial work around smaller Scottish places tends to mean hotels, guest houses, schools and halls rather than offices. All of them have washrooms, kitchens and fire-rated joints that need looking after.
The work is covered for a year after we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Do not fill fire-stopping gaps with ordinary foam or silicone
- Report cracked or damaged seals as soon as you notice them
- Allow for resealing whenever new services are run
- Do not paint over fire sealant until it has cured
Avoid covering a sealed gap with anything that isn’t part of the tested detail. If it needs repair, use the same type of product. We can tell you which product we used.
A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Closing it is usually a straightforward job.

What sealant work cannot fix
We’ll always be straight with you, so here’s what new sealant won’t do:

- 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 will give you a straight answer before you book.

Do Scottish building rules affect fire-rated sealant work in Forth?
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.

The location, the problem and the rough size of the job. Photos by email help too.
Can you match the sealant colour?
Yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before any work starts.

Yes. We work in flats, HMOs, schools, offices and other commercial buildings, including occupied ones. We agree access and the order of work with you first.

How we quote for fire rated sealant
We quote each job individually. These are the things that affect it:
- How many areas need sealing
- Working hours on commercial sites
- Whether there’s mould to deal with
- The product the joint needs
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- If someone has resealed it before
- A few pictures by email, if you can
- Access, such as stairs, a lift or height
- The rough size of the job
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. Whenever you’re ready, send an email to info@mrmastic.co.uk.
Different surfaces, different methods
Service penetrations
A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. Each one is sealed to the product’s tested detail.
Flats and HMOs
In flats and HMOs, the walls and floors between homes and common areas need sealing where services pass through. We work through the gaps on your assessment room by room.
What we are called out for in Forth
In some buildings the gap was filled with the wrong thing in the first place: general-purpose foam, everyday silicone or caulk where a fire-rated seal was needed. It may look fine, but it isn’t a fire-rated seal.
The problems people normally mention when they call are:
- Sealant items on a fire risk assessment action list
- Gaps where walls meet ceilings or slabs
- Cracked or shrunken fire-rated sealant
- Ordinary sealant used where a fire-rated product was needed
Around Forth, as everywhere, fire rated sealant is only as good as the preparation behind it.
