About our fire rated sealant in Lockerbie
In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. One new cable or pipe can leave a gap that nobody goes back to seal. Those are the gaps we close, using a tested fire-rated product. We are often asked to deal with gaps left after a refit or conversion and gaps where walls meet ceilings or slabs, across service penetrations, plasterboard & masonry and door frames.
For holiday lets, guest houses and community buildings in or near Lockerbie, 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 there’s a problem with our work within the year, let us know and we will sort it.

DIY sealant or a professional job?
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.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Tell trades working in the building that fire seals must be put back
- Look in service cupboards and ceiling voids from time to time
- Never patch a fire seal with standard sealant
- Keep the record of products and locations with your fire safety documents
Any fire seal that is cut or drilled needs resealing to its tested detail. New services through a sealed wall should include fire stopping in the plan.
Any job that breaks through a wall or ceiling should include resealing. Doing it at the time avoids leaving gaps behind.
Landlord and commercial work in Lockerbie

Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we’re fully insured.
Leave it or put it right?
A quick fill with any sealant to hand isn’t fire stopping. A fire-rated product only performs as tested when it’s installed to its tested detail, which is why we match the product and the method to each gap. In an older home around Lockerbie, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll explain what it covers.

How it works
At the end, we look at the finished work together and explain the cure time. The visit itself usually takes from a few hours to a few days, depending on the number of gaps and the access, depending on the amount of work. Outside jobs in Lockerbie need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- We plan the order of work and access, floor by floor or flat by flat.
- Old, damaged or unsuitable sealant is removed.
- Dust and loose debris are cleaned from each gap.
- We apply and tool the sealant to the product’s tested detail.
- We record what was done and flag anything that needs a different system.
Before we arrive
- Clear items away from the joints we are working on
- Mention if the joints have been sealed before
- Let us know if you’ve seen damp or leaks

FAQs for Lockerbie
How do Scotland’s building regulations apply to fire-rated sealant in Lockerbie?
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 is 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 Lockerbie within the area you cover?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
What does fire rated sealant cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.
Do you provide details of the products used?
Yes. Locations and products are written up when we finish. If you need photos or a set layout, ask when you get a quote.
Do you guarantee your work?
Yes: twelve months. If anything is not right with the work within the year, let us know and we will sort it.
What information do you need?
Only a few details: the address or postcode, what’s wrong and any access issues. Then send an email to info@mrmastic.co.uk.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
