North Dell Fire Rated Sealant
Problem with your fire-stopping gaps in North Dell? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Door frames with gaps between frame and wall
- Damaged fire sealant left by other trades
- Unsealed gaps where pipes and cables go through a wall
Why deal with it now?
Fire-rated sealants are less forgiving than ordinary ones. Depth, backing and surface preparation all affect how a seal performs, so we follow the maker’s details on every gap. Around North Dell, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

Fire rated sealant for homes and businesses in North Dell
Until it’s heated, intumescent sealant behaves like an ordinary sealant; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through. We work on linear gaps, door frames and plasterboard & masonry, and people most often call us about gaps filled with a product that isn’t fire-rated and open holes round services passing through fire walls.
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.
All our work comes with a one-year guarantee, wherever you are in Na h-Eileanan Siar.

Fire-rated sealant is installed to the manufacturer’s tested details, though we do not certify buildings or do fire risk assessments.

Advice
FAQs for North Dell
Can you do fire rated sealant in North Dell?
Yes, North Dell is within the area we cover. Our work covers the whole of Scotland. You can send an email to info@mrmastic.co.uk and let us know what needs doing.
Is North Dell within the area you cover?
Yes. North Dell 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.
Is standard sealant good enough for a fire gap?
No. Standard sealants aren’t made or tested to stop fire. If it’s been used, we remove it and use the right product.
Can you give us a record of the work?
Yes. Every gap we seal is listed with the product used.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What fire rating will the seal have?
Ratings and certification sit with the product’s test evidence and whoever specified the work. We apply the specified product to the manufacturer’s details and giving you a record of where it went.
Is there any odour?
Possibly a little. It fades as the sealant cures, and ventilation helps.
How we quote for fire rated sealant
For a quick quote, just ask. What matters most is:
- The amount of work
- How many areas need sealing
- Whether there’s mould to deal with
- Which sealant suits the joint
The cost reflects the work involved, not guesswork. That is why we ask about the job first.
Helping us quote
Before you ask for a quote, have a think about:
- If someone has resealed it before
- How we’d reach the joints
- What’s wrong with the joints now
- The rough size of the job
For a quote, drop us a line at info@mrmastic.co.uk with the location and a short description of the problem. You will have a clear quote before work begins.
Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
What we’re called out for in North Dell
Many open fire-stopping gaps are made after the building is finished. Electricians, plumbers and data installers drill through walls and ceilings and the hole they leave doesn’t always get resealed.
If you can see any of these, it’s time to have the joints looked at:
- Gaps left after a refit or conversion
- Door frames with gaps between frame and wall
- Gaps filled with a product that isn’t fire-rated
- Open holes round services passing through fire walls
Around North Dell, as everywhere, fire rated sealant is only as good as the preparation behind it.
Before you book anyone
- The length of the guarantee
- Whether the sealant suits the joint
- How much experience the applicator has
- What the quote includes, VAT included or not
Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Keep the record of products and locations with your fire safety documents
- Get damaged fire seals looked at promptly
- Check whether a sealant can be painted before decorating over it
- Take pictures of fire stopping before ceilings or boxing go back
Do not drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.
Open gaps do not only matter in a fire: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.
