DIY sealant or a professional job?
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.
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.
Fire rated sealant in Garlieston
Intumescent sealant looks much like any other sealant until it gets hot; in a fire it expands into the joint. The right product depends on the gap size, the substrate and what passes through, so we follow the tested detail for each one. If you have gaps around pipes and cables through fire-resisting walls and ordinary sealant used where a fire-rated product was needed, we can put it right.
For holiday lets, guest houses and community buildings in or near Garlieston, the washrooms and kitchens need the same care as any city building, and fire-rated joints should be kept in good order.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

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. In an older home around Garlieston, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
We don’t show prices on the website, because each job is priced on what it involves. For a quick quote, please drop us a line at info@mrmastic.co.uk.

The process
We keep the work tidy and contained to the joints we’re treating. Expect the work to take anything from a few hours to several days, depending on how many gaps there are, and we tell you how long to leave it before we go. Outdoor work around Garlieston depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- Old or unsuitable sealant is cut out and the gap 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.
- We record the locations and products used for your records.
How to prepare
- Clear items away from the joints we’re working on
- For indoor joints, keep the area dry beforehand if you can
- For business premises, tell us about site rules or sign-in

How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Never patch a fire seal with standard sealant
- Check risers, ceiling voids and cupboards during building checks
- Ask which product was used before you paint
- Photograph sealed gaps before they’re covered up
Avoid covering a sealed gap with anything that isn’t part of the tested detail. If it needs repair, use the same type of product. Ask us if you’re not sure which product was used.
A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded so the item can be closed.
Garlieston: your questions answered
Do you cover Garlieston for fire rated sealant?
Yes. We work across all of Scotland, and Garlieston is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job.
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. Whatever the rules, fire-rated sealant has to be installed to the manufacturer’s tested details, and that’s how we fit it. We do not certify buildings or do fire risk assessments; your assessor or building control can tell you what’s required.
Is there any odour?
Possibly a little. It fades as the sealant cures.
Will you assess my building’s fire safety?
No, we do not assess buildings. Once you have a specification or action list from your assessor or designer, we’ll quote for the sealant work on it.
Can you work in occupied 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.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Can you match the sealant colour?
Most of the time, yes. We will explain which colours are available.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. Then drop us a line at info@mrmastic.co.uk.
When to call us in Garlieston
Gaps also open up as buildings move: cracked or debonded sealant leaves an open route through the wall. Damage from cleaning, knocks and maintenance adds to it.
The problems people generally mention when they call include:
- Linear gaps at the head of walls
- Standard silicone or caulk in a fire-stopping gap
- Unsealed gaps around fire door frames
- Sealant items on a fire risk assessment action list
Whether the job is in Garlieston itself or nearby, the right material for each joint matters as much as a neat finish.
Questions to ask before booking
- Which sealant they’ll use, and why
