Why it’s worth doing now in Shawbost
An unsealed gap lets smoke and fire get round a wall that was built to hold them back. Sealing it properly restores what the wall was there to do, and the work involved is often modest. Around Shawbost, 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.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we’ll go through it with you.

The process
On the day, we look over the joints with you first. Surfaces next to the work are protected before any work begins. Most jobs take a few hours for a handful of gaps, and longer for a whole building. Somewhere like Shawbost may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- 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 faces cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- We hand over a list of locations and products for your records.
Preparing for the visit
- Mention if the joints have been sealed before
- Keep pets and children clear of the area while we work

FAQs for Shawbost
Do you cover Shawbost for fire rated sealant?
Yes. We work across all of Scotland, and Shawbost is part of that. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing, and we’ll give you a clear price.
Are the rules for fire-rated sealant different in Scotland?
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 carry out fire risk assessments, so your fire risk assessor or building control will advise on what’s needed.
Are you insured?
Yes, we are fully insured.
What does fire rated sealant cost?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Can I use normal mastic around a pipe through a fire wall?
No. A gap that needs fire stopping needs a tested fire-rated product, installed to its details.
Can new sealant go over the old?
No, it won’t last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
How long does the job take?
Typically it takes a few hours for a handful of gaps, and longer for a whole building. Bigger jobs take longer, and we’ll say how long yours will take.
Do you need fire rated sealant in Shawbost?
Gaps around door frames are easily missed. 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 where walls meet ceilings or slabs
- Unsealed gaps around fire door frames
- New service routes left unsealed after building work
- Standard silicone or caulk in a fire-stopping gap
In and around Shawbost, as anywhere, good fire rated sealant starts with a clean, dry, properly prepared joint.

When it is not the sealant
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Certifying a building or signing off its fire safety
- Doors that are not fire doors in the first place
- Assessing a building’s fire safety
If you are not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer before you book.
What we seal
- Linear gaps
- Flats & HMOs

Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

Aftercare tips
Good habits help new joints last longer. Our tips:
- Take photos of fire stopping before ceilings or boxing go back
- Include fire stopping when you schedule refits
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Get damaged fire seals looked at promptly
Follow the cure time we give you before decorating over the sealant. Not every fire-rated sealant takes paint.
Any job that breaks through a wall or ceiling should include resealing. Catching it then saves a separate visit later.
