Fire rated sealant in North Tolsta
Door frame gaps, linear joints and holes around services all have their own details. Measuring the gap and checking what it’s made of comes first, then apply it to the depth its tested detail calls for. If you are dealing with ordinary sealant used where a fire-rated product was needed and fire seals that have cracked with movement, we can put it right, whatever the surface.
For a place like North Tolsta, the journey and timings are planned in advance, so the job can fit around guests, residents or opening hours where possible.
Big or small, it’s backed by our 12-month guarantee.

Why act early in North Tolsta
Sealant is not the fix for every opening. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. If a gap is not suitable for sealant, we will tell you. In a place like North Tolsta, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

Other services in North Tolsta
Surface by surface
Masonry and concrete
For masonry and concrete, we use a product tested in that substrate. We clean out dust and debris before sealing.
Linear gaps
Head-of-wall gaps are often hidden above suspended ceilings. We seal them along their full length so there are no open sections left.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Ask every contractor to reseal any fire stopping they disturb
- Ask which product was used before you paint
- Never patch a fire seal with standard sealant
- Photograph sealed gaps before they’re covered up
Include fire stopping in your regular building checks. Watch for cracking, gaps or seals that have been disturbed and get them seen to.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.
When it is not the sealant
We’d rather tell you now than do work that won’t last, so these are the limits:
- Openings too large for sealant, which need batts, boards or another system
- Fire risk assessments, which need a qualified assessor
- Sign-off of the building, which sits with building control or your assessor
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think.

Your questions about fire rated sealant in North Tolsta
Do you cover smaller places like North Tolsta?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland, including the islands, where work is planned around ferry crossings. Just mention lanes, gates or anything else about the route when you book.
Do Scottish building rules affect fire-rated sealant work in North Tolsta?
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 do fire risk assessments; your assessor or building control can tell you what’s required.
Can you match the sealant colour?
Generally, yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before work begins.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status.
Can you tell me which gaps need fire stopping?
No, we do not assess buildings. Once you have a specification or action list from your assessor or designer, we’ll quote for the sealant work on it.
Where are you based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
How long does the job take?
It depends on the size of the job, but most jobs take a few hours for a handful of gaps, and longer for a whole building. We will give you a better idea when we quote.
