Fire rated sealant for homes and businesses in Sandwick
Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. Each gap is sealed to the product maker’s tested detail for its size and substrate, and we can record what went where. We work on service penetrations, plasterboard & masonry and flats & HMOs, and the jobs we see most are gaps left after a refit or conversion and standard silicone or caulk in a fire-stopping gap.
If you look after holiday lets, a guest house or a community building in or near Sandwick, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.

What sealant work cannot fix
To be straight with you, some problems need a different trade:
- Certifying a building or signing off its fire safety
- A wall that isn’t a fire-resisting element to begin with
- Fire risk assessments, which need a qualified assessor
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think before you book.
Surfaces we seal
- Door frames
- Plasterboard & masonry
- Service penetrations
- Pipe & cable gaps
- Flats & HMOs
- Linear gaps
Common problems we fix in Sandwick
Door frames are a common weak spot. The gap between the frame and the wall is hidden behind the architrave, so it’s easy to leave unsealed when doors are changed.
These are the problems we are asked about most:
- Gaps filled with a product that is not fire-rated
- New service routes left unsealed after building work
- Unsealed gaps around fire door frames
- Sealant items on a fire risk assessment action list
Around Sandwick, as everywhere, fire rated sealant is only as good as the preparation behind it.
Before you book anyone
- Are they insured?
- Whether they seal over old material or remove it
- When the joint can take water or movement
- Who turns up on the day
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
How to look after the new joints
Looking after new joints is easy:
- Keep the record of products and locations with your fire safety documents
- Plan fire stopping into any work that goes through walls or floors
- Look in service cupboards and ceiling voids from time to time
- Never patch a fire seal with standard sealant
Let contractors know where fire stopping has been done, and make sure anything they disturb is resealed with a suitable product. A lot of damaged fire stopping comes from later work.
A flagged gap shouldn’t wait for the next assessment. Have it sealed, then keep the record so you can show it was dealt with.
Sandwick questions
Do Scottish building rules affect fire-rated sealant work in Sandwick?
Building work in Scotland comes under the Building (Scotland) Regulations and their technical handbooks. Fire-rated sealant has to go in to the product’s tested details, and we follow them. We do not certify buildings or do fire risk assessments; your assessor or building control can tell you what’s required.
Do you cover smaller places like Sandwick?
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.
Can you give us a record of the work?
Yes. We note each location and the product that went in.
How much does fire rated sealant cost in Sandwick?
Size, access and the old material all affect the cost. Call for a quick quote.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Do you work in flats, HMOs and commercial buildings?
Yes, whether the building is a school, an office, flats or an HMO, and whether it’s in use or not. Tell us how the building is used and we’ll plan around it.
Can I use normal mastic around a pipe through a fire wall?
No. Where a fire-rated seal is needed, it has to be a product tested for that use fitted to the maker’s details.
