What we cannot put right
In fairness, some problems need a different trade:
- 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
- A wall that isn’t a fire-resisting element to begin with
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly.

Can I do it myself?
If you are set on DIY, put the effort into 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. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
What affects the cost of fire rated sealant
The price is agreed before any work begins. It takes into account:
- Any mould that needs treating
- Access and height
- The number of rooms or windows
- The product the joint needs
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.
What we need to know
What to tell us when you ask for a quote:
- What’s wrong with the joints now
- The address or postcode of the job
- The rough size of the job
- If someone has resealed it before
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
FAQs for Walkerburn
How do Scotland’s building regulations apply to fire-rated sealant in Walkerburn?
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 don’t certify buildings or carry out fire risk assessments, so your fire risk assessor or building control will advise on what’s needed.
Will you come out to Walkerburn?
Yes, Walkerburn is covered. We work across all of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you offer different sealant colours?
Yes. White, clear and grey are common, and other colours are available, and we’ll agree it with you first.
Will the old sealant be removed?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
Are you fully insured?
Yes. We are fully insured, and we’ve been doing sealant work for more than 20 years.
What does intumescent mean?
Intumescent describes a material that swells in heat. Intumescent sealants are a type of fire-rated sealant and which one is used depends on the job.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little.
How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Include fire stopping when you schedule refits
- Include hidden areas like risers in routine checks
- Make resealing part of every contractor’s brief
- Get damaged fire seals looked at promptly
Include fire stopping in your regular building checks. Watch for cracking, gaps or seals that have been disturbed and have them put right.
An open gap is not only a fire issue: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.
What we do, step by step
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it normally takes anything from a few hours to several days, depending on how many gaps there are. Outside jobs in Walkerburn 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.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Old or unsuitable sealant is cut out and the gap cleaned.
- Where the tested detail needs backing or fill, we fit it.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Locations and products are noted so you have them on file.
Preparing for the visit
- Tell us if parking is tricky
- Mention any tricky access
- Mention any leaks or damp you’ve noticed

Service penetrations
Service penetrations are where new gaps often appear. We clean out what’s there and reseal to the right depth.
Linear gaps
Long, narrow gaps appear where walls meet slabs and ceilings. We seal them to the tested detail, with backing where it’s needed.
