Fire rated sealant for homes and businesses in Tong
Deciding which gaps need fire stopping isn’t our role; your assessor, designer or building control sets that out. Our part is applying the specified sealant carefully, to the right depth and with the right backing. We work on linear gaps, plasterboard & masonry and service penetrations, and common reasons people get in touch are gaps around pipes and cables through fire-resisting walls and unsealed gaps around fire door frames.
For a place like Tong, the journey and timings are planned in advance, so the job can fit around guests, residents or opening hours where possible.
You get a one-year guarantee, the same in Tong as everywhere else we work.

Your questions about fire rated sealant in Tong
How do Scotland’s building regulations apply to fire-rated sealant in Tong?
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.
Is Tong in your area for fire rated sealant?
Yes, Tong is within the area we cover. Our work covers the whole of Scotland. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing, and we will send you a clear quote.
Will we have a record of what was sealed?
Yes. Every gap we seal is listed with the product used so it’s there for the next inspection.
Is standard sealant good enough for a fire gap?
No. A gap that needs fire stopping needs a tested fire-rated product.
Can you fill the gap behind a fire door frame?
Yes. We often seal open gaps hidden behind the architrave. Doors, seals and closers need a door specialist.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme.
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. We remove it all first.
Where is Mr Mastic based?
We work from Crawley. We cover Tong and the rest of Na h-Eileanan Siar, along with the rest of our area.
DIY versus a professional finish
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.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.

Looking after it afterwards
So the new joints stay in good condition:
- Keep pictures of seals that will be hidden
- Plan fire stopping into any work that goes through walls or floors
- Do not paint over fire sealant until it has cured
- Do not fill fire-stopping gaps with ordinary foam or silicone
Let contractors know where fire stopping has been done, and make sure anything they disturb is resealed with a suitable product. Later work is a common cause of damaged fire stopping.
A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Sealing it early is a simple step to take.
Why deal with it now?
For some gaps, sealant is not the right answer and another system is needed. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. If a gap isn’t suitable for sealant, we’ll tell you. In an older home around Tong, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

Advice
What the job involves on each surface
Flats and HMOs
Converted houses often have gaps around old and new services. The gaps on your list are sealed with a fire-rated product and record where they are.
Linear gaps
Long, narrow gaps appear where walls meet slabs and ceilings. We seal them to the tested detail, with backing where it’s needed.
When something else is needed
New sealant can’t fix everything, and we’ll tell you before we start. It won’t solve:
- A wall that is not a fire-resisting element to begin with
- Doors that are not fire doors in the first place
- Large holes that need a different fire-stopping system
If you’re not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer before you book.
