Fire Rated Sealant in Grimbister
Fire-stopping gaps in Grimbister need attention? We remove the old material, prepare the joints and seal them properly.
- Standard silicone or caulk in a fire-stopping gap

- Damaged fire sealant left by other trades
Fire rated sealant in Grimbister, done properly
Door frame gaps, linear joints and holes around services all have their own details. We check the size and the substrate before choosing the product, then apply it to the depth its tested detail calls for. If you have open gaps behind door architraves and ordinary sealant used where a fire-rated product was needed, we can help, whatever the surface.
In a smaller place like Grimbister, 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.
You get a 12-month guarantee, the same in Grimbister as everywhere else we work.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
Grimbister questions
Do you cover Grimbister for fire rated sealant?
Yes, Grimbister is within the area we cover. Our work covers the whole of Scotland. You can send an email to info@mrmastic.co.uk and tell us what needs doing.
Will you come out to Grimbister?
Yes. Grimbister is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland, including the islands, where work is planned around ferry crossings. Let us know about access, parking and anything unusual about getting there when you book.
Can I choose the sealant colour?
Yes. Sealants come in white, clear, grey and other colours, and we’ll agree it with you first.
Can you do several jobs on one visit?
Yes. Just list everything you need.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. Then drop us a line at info@mrmastic.co.uk.
Do you carry out fire risk assessments?
No. We follow the requirements from your assessor, designer or building control, and apply each product to its tested details.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Will the old sealant be removed?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
What happens if it’s left?
Leaving a gap until a refurbishment comes round can mean years with it open. On its own, sealing it now is a small job that doesn’t depend on other work. In an older home around Grimbister, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Ask us for a quote and we’ll go through it with you.

What the job involves on each surface
Service penetrations
New gaps tend to show up where services have been added. Old or unsuitable filler comes out before the right sealant goes in over any backing the detail calls for.
Door frames
We deal with the gap around the frame, not the door. Doors, seals and closers are for a door specialist and we will mention anything we notice.
Aftercare tips
Aftercare is simple, and it makes a real difference:
- Take pictures of fire stopping before ceilings or boxing go back
- Do not paint over fire sealant until it has cured
- Look in service cupboards and ceiling voids from time to time
- Report cracked or damaged seals as soon as you notice them
Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. A lot of damaged fire stopping comes from later work.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is normally a straightforward job.
What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a handful of gaps, and longer for a whole building, and the area is left clean. Around Grimbister, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- Before starting, we go through the specification or action list with you.
- We measure every gap and note what it’s in and what passes through.
- Any non-fire-rated filler is removed and the gap cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used for your files.
Preparing for the visit
- Keep children and pets away from the work area
- Tell us about any previous sealing or DIY attempts
- Mention any tricky access
Ask for a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.
