Should I try it myself first?
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.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
About our fire rated sealant in Longforgan
Ordinary silicone or decorators’ caulk in a fire-stopping gap isn’t a fire-rated seal. Anything unsuitable comes out first and reseal with a fire-rated product tested for that kind of gap. We’re often asked to deal with linear gaps at the head of walls and old fire sealant that has split or come away, on plasterboard & masonry, linear gaps and flats & HMOs.
In a smaller place like Longforgan, commercial jobs are more likely to be a hotel, guest house, school, surgery or community hall than an office block. Each needs sound sealant in its washrooms and kitchens, and fire-rated joints kept in good order.
Big or small, it’s backed by our one-year guarantee.

When something else is needed
It helps to know what we can’t do too:
- Doors that aren’t fire doors in the first place
- Construction that does not provide fire resistance on its own
- Deciding what fire stopping a building needs

Where we work in Longforgan
- Plasterboard & masonry
- Linear gaps
- Service penetrations
- Flats & HMOs
- Door frames
- Pipe & cable gaps
Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
What we’re called out for in Longforgan
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.
The problems people normally mention when they call are:
- Sealant items on a fire risk assessment action list
- Fire stopping disturbed by later work
- Open joints along the top of partitions
- Fire seals that have cracked with movement
For landlords with property near Invergowrie station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Surface by surface
Service penetrations
Wherever a service goes through a fire-resisting wall or floor, there’s a gap around it. We seal it with a product tested for that service and gap size.
Masonry and concrete
Holes through concrete and block are rarely neat. We check the gap size around the service to make sure it suits the product.

Keeping the joints in good condition
So the new joints stay in good condition:
- Ask every contractor to reseal any fire stopping they disturb
- Keep the record of products and locations with your fire safety documents
- Include hidden areas like risers in routine checks
- Do not fill fire-stopping gaps with ordinary foam or silicone
Leave the sealant to cure fully before painting near it. Some fire-rated sealants can be painted and some cannot.
An open gap isn’t only a fire issue: noise, draughts and even pests can come through too. Sealing them early helps on every front.
Commercial buildings in Longforgan
If you run a hotel, guest house or holiday let in a coastal place like Longforgan, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. Scotland has its own building regulations, the Building (Scotland) Regulations, with technical handbooks. Fire-rated sealant is installed to the manufacturer’s tested details; we don’t certify buildings or carry out fire risk assessments.
Community buildings like Longforgan Parish Church are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

How it works
There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The work itself takes anything from a few hours to several days, depending on how many gaps there are. Outside jobs in Longforgan need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- Before starting, we go through the specification or action list with you.
- Each gap is measured and its substrate and service noted.
- Unsuitable material such as ordinary foam or silicone is cut out and the gap cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used.
Before we arrive
- Keep pets and children clear of the area while we work
- Tell us about any previous sealing or DIY attempts
- Tell us if parking is tricky

Longforgan questions
Can you help a landlord with a rental near Invergowrie station?
Yes, landlords and agents are among the people we work for. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear price.
Do you cover smaller places like Longforgan?
Yes. Longforgan is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
How much does fire rated sealant cost in Longforgan?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
What’s the difference between intumescent and fire-rated sealant?
An intumescent sealant expands when it gets hot, helping close the gap. It’s one type of fire-rated sealant; which product suits depends on the gap, the substrate and the service.
Do you work in flats, HMOs and commercial buildings?
Yes. We work in flats, HMOs, schools, offices and other commercial buildings, including occupied ones. We agree access and the order of work with you first.
Will you assess my building’s fire safety?
No, assessment is not something we do. When your assessor or designer has set out what’s needed, we’ll quote for the sealant work on it.
Can I use normal mastic around a pipe through a fire wall?
No. Where a fire-rated seal is needed, it has to be a product tested for that use fitted to the maker’s details.
