Questions from Steinis
Do you cover smaller places like Steinis?
Yes. Steinis 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. Just mention lanes, gates or anything else about the route when you book.
Do Scottish building rules affect fire-rated sealant work in Steinis?
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 carry out fire risk assessments, so your fire risk assessor or building control will advise on what’s needed.
Is intumescent sealant the same as fire-rated sealant?
An intumescent material expands when it’s heated. Intumescent sealants are a type of fire-rated sealant and which one is used depends on the job.
I rent my home. Can I book you?
We are happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
Do you provide details of the products used?
Yes. We note each location and the product that went in so it’s there for the next inspection.
What fire rating will the seal have?
We do not certify fire stopping or quote ratings. Our part is installing the specified product to its tested details and list the locations and products for you.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
Can you seal over the old sealant?
No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Fire rated sealant for homes and businesses in Steinis
Until it’s heated, intumescent sealant behaves like an ordinary sealant; then it swells to help close the gap. Which product suits a gap depends on its width, the materials either side and what runs through it, so we work to the manufacturer’s details. We work on linear gaps, flats & HMOs and plasterboard & masonry, and common reasons people get in touch are holes left by a change of layout and seals cut through by electricians, plumbers or data installers.
For a place like Steinis, the journey and timings are planned in advance, so the job can fit around guests, residents or opening hours where possible.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

What we do, step by step
Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes from a few hours to a few days, depending on the number of gaps and the access. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Anything that isn’t fit for the job comes out, and the gap is cleaned.
- We put in whatever backing or fill the product detail specifies.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- Locations and products are noted so you have them on file.
How to prepare
- Let us know if you’ve seen damp or leaks
- Let us know about earlier repairs to the joints
- Mention any tricky access
How to get a quote

Can I do it myself?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
When to call us in Steinis
A lot of fire stopping is out of sight: above ceilings, inside risers and behind panels. Out of view, damage sits unnoticed until someone inspects.
Any of these means the joints need attention:
- Open holes round services passing through fire walls
- Old fire sealant that has split or come away
- Door frames with gaps between frame and wall
- Holes left by a change of layout
For jobs in and around Steinis, choosing the right material for each joint is as important as a tidy finish.

What to tell us for a quote

- Whether it’s a home or a business

Need a quote? Please send an email to info@mrmastic.co.uk and tell us about the job. We will explain what we’d do and give you a clear quote before any work starts.
What we can’t put right
In fairness, there are a few things sealant will not fix:
- Construction that does not provide fire resistance on its own
- Sign-off of the building, which sits with building control or your assessor
- Openings too large for sealant, which need batts, boards or another system
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think before you book.
Joints and surfaces we work on
- Service penetrations
- Pipe & cable gaps
- Plasterboard & masonry
- Flats & HMOs
- Door frames
- Linear gaps
Aftercare tips
Aftercare is simple, and it makes a real difference:
- Include hidden areas like risers in routine checks
- Check whether a sealant can be painted before decorating over it
- Flag any open gap you spot round a pipe or cable
- Photograph sealed gaps before they’re covered up
Let contractors know where fire stopping has been done, and make sure anything they disturb is resealed with a suitable product. Later work is a common cause of damaged fire stopping.
A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Sealing it early is a simple step to take.
Different surfaces, different methods
Door frames
Our work is the joint between frame and wall. Doors, seals and closers are for a door specialist and we’ll mention anything we notice.
