Fire rated sealant in Thurso, done properly
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. If you have sealant items on a fire risk assessment action list and gaps left after a refit or conversion, we can put it right.
Scotland has its own building regulations, the Building (Scotland) Regulations, but whatever the building, fire-rated sealant has to be installed to the product’s tested details. For any building in Thurso, that applies just the same.
All our work comes with our one-year guarantee, wherever you are in Highland.

FAQs for Thurso
Can you help a landlord with a rental near Thurso station?
Yes, we work for landlords and letting agents. You can email us at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before work begins.
Is Thurso in your area for fire rated sealant?
Yes. We work across all of Scotland, and Thurso is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we will send you a clear quote.
Can you do several jobs on one visit?
Yes, we can. More than one area can go on one quote.
How long does the job take?
As a guide, most jobs take a few hours for a handful of gaps, and longer for a whole building. Larger jobs naturally take longer, and we will tell you how long to expect.
Are you fully insured?
Yes, we are fully insured for every job we do.
Can you tell me which gaps need fire stopping?
No, assessment is not something we do. When your assessor or designer has set out what’s needed, we’ll quote for the sealant work on it.
Can ordinary silicone be used in a fire-stopping gap?
No. It might close the gap, but it isn’t a fire-rated seal. A tested fire-rated product is needed.
Can new sealant go over the old?
No, because it fails. We remove every bit of old sealant first.
DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
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.

How to look after the new joints
Good habits help new joints last longer. Our tips:
- Don’t fill fire-stopping gaps with ordinary foam or silicone
- Store the list of sealed gaps with your building paperwork
- Look in service cupboards and ceiling voids from time to time
- Get damaged fire seals looked at promptly
Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some can’t.
It’s easiest to seal gaps while they’re few and easy to reach. Over time, more work adds more holes and the job gets bigger.
Signs you need fire rated sealant in Thurso
Lots of unsealed gaps appear long after the building was completed. New cables, pipes and data runs go through walls and ceilings and the hole they leave doesn’t always get resealed.
These are the problems we’re asked about most:
- Open gaps behind door architraves
- Gaps around pipes and cables through fire-resisting walls
- Cracked or shrunken fire-rated sealant
- Damaged fire sealant left by other trades
Rented homes near Thurso station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product.
What your quote should include
- How the joint is cleaned and prepared
- Whether they seal over old material or remove it
- How the colour is chosen
- Which sealant they’ll use, and why
How the job changes by surface
Flats and HMOs
In occupied buildings, we plan the order of work with you. We agree access to each flat and the common parts before any work starts so residents know what to expect.
Door frames
Our work is the joint between frame and wall. The door leaf, its seals and closer need a door specialist and we will mention anything we notice.
When it isn’t the sealant
We will always be straight with you, so here’s what new sealant will not do:
- Sign-off of the building, which sits with building control or your assessor
- Fire doors that need new seals, closers or hardware
- Walls or floors that weren’t built to resist fire
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think before you book.
Surfaces we seal
- Flats & HMOs
- Door frames
- Linear gaps
- Service penetrations
- Pipe & cable gaps
- Plasterboard & masonry
Workplaces and buildings in Thurso
If you run a hotel, guest house or holiday let in a coastal place like Thurso, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. In Scotland, building work comes under the Building (Scotland) Regulations and their technical handbooks. We install fire-rated sealant to the product’s tested details; we do not certify buildings or carry out fire risk assessments.
For site and facilities teams at buildings such as Thurso High School, fire-stopping around service openings should be restored whenever new services go in.
