Fire rated sealant in Letham, done properly

We work on linear gaps, flats & HMOs and pipe & cable gaps, and people most often call us about gaps flagged on a fire risk assessment and fire stopping disturbed by later work.
For a place like Letham, the journey and timings are planned in advance, so the job can fit around guests, residents or opening hours where possible.
Whatever the size of the job, you get the same one-year guarantee in Letham and across Perth and Kinross.

Questions from Letham
Are the rules for fire-rated sealant different in Scotland?
Scotland has its own building regulations, the Building (Scotland) Regulations, with their own technical handbooks. Fire-rated sealant has to go in to the product’s tested details, and we follow them. 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.
Do you cover smaller places like Letham?
Yes, Letham is covered. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Can you tell me how many minutes the seal will last?
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 list the locations and products for you.
How long will you be here?
Most jobs take anything from a few hours to several days, depending on how many gaps there are. Your quote will say how long we expect yours to take.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
Can you work in occupied buildings?
Yes. We regularly work in flats, HMOs, schools and offices while they’re in use and we plan access around the people using them. Early starts or out-of-hours work can be arranged where it’s needed.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.

What else we do in Letham
How it works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes from a few hours to a few days, depending on the number of gaps and the access and we leave things clean and tidy. Outside jobs in Letham need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- Access to each area is agreed so the work can run in order.
- We take out any damaged or unsuitable sealant.
- Gaps are cleaned of dust and loose material.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
Getting ready for the visit
- Mention any tricky access
- For indoor joints, keep the area dry beforehand if you can
- Move anything stored near the joints

Quotes for fire rated sealant in Letham
Every job gets its own quote. These are the things that affect it:
- The size of the job
- Whether there’s mould to deal with
- The number of rooms or windows
- Whether the work is at height
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
What we need to know
You do not need to know the technical terms. It helps if you can tell us:
- How many joints, rooms or windows are involved
- Whether it’s a home or a business
- Where the job is, and your postcode
- Photos by email, if that is easy
Call for a quick quote, or email us if that’s easier. Tell us about the joints that need doing and we’ll explain what’s involved.
When something else is needed
Sealant isn’t the answer to every problem, and we’ll tell you before work begins. Sealant will not put right:
- Problems with the door itself rather than the gap around the frame
- Large holes that need a different fire-stopping system
- Fire risk assessments, which need a qualified assessor
If you are not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer.
Joints and surfaces we work on
- Plasterboard & masonry
- Flats & HMOs
- Service penetrations
- Door frames
- Pipe & cable gaps
- Linear gaps
Surface by surface
Service penetrations
Different services need different details: metal pipes, cables and plastic pipes are not treated the same. We follow the manufacturer’s tested detail for each.
Plasterboard walls
In plasterboard walls, the condition of the board edge matters. Crumbling edges are cleaned back before the sealant goes in.
DIY sealant or a professional job?
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.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Leave it or put it right?
Fire-rated sealants need more care than everyday sealant. Depth, backing and surface preparation all affect how a seal performs, and we work to the product details every time. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, email us at info@mrmastic.co.uk and we will give you an honest view and a quote.
