How we handle fire rated sealant in Bonhill
In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. A new cable run or a replaced pipe can leave an open hole behind. We seal them with a product tested for that kind of gap. Common call-outs are for cracked or shrunken fire-rated sealant and sealant items on a fire risk assessment action list, on flats & HMOs, pipe & cable gaps and plasterboard & masonry.
For holiday lets, guest houses and community buildings in or near Bonhill, the washrooms and kitchens need the same care as any city building, and fire-rated joints should be kept in good order.
We stand behind the work with a 12-month guarantee.

What we do, step by step
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes anything from a few hours to several days, depending on how many gaps there are. Outdoor work around Bonhill depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- Each gap is measured and its substrate and service noted.
- Unsuitable material such as ordinary foam or silicone is cut out.
- The specified fire-rated sealant goes in over any backing its detail requires.
- We hand over a list of locations and products for your files.
How to prepare
- Try not to wet indoor joints just before the visit
- Tell us about access, such as stairs, a lift or high-level joints
- For business premises, tell us about site rules or sign-in

What else we do in Bonhill
Signs you need fire rated sealant in Bonhill
Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk where a fire-rated seal was needed. It looks sealed, but it isn’t fire-rated.
Any of these means the joints need attention:
- Gaps flagged on a fire risk assessment
- Gaps filled with a product that is not fire-rated
- Unsealed gaps where pipes and cables go through a wall
- Holes left by a change of layout
If you look after a building such as Vale of Leven Academy, service openings in fire-resisting walls need checking after any refurbishment.

Commercial buildings in Bonhill
If you run a hotel, guest house or holiday let in a coastal place like Bonhill, 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, though we do not certify buildings or do fire risk assessments.
If you let a flat or house near Alexandria station, any gap left by new services in shared walls should be closed with a fire-rated product.

How the job changes by surface
Service penetrations
Service penetrations are where new gaps often appear. Old or unsuitable filler comes out before the right sealant goes in.
Linear gaps
Some linear gaps have to cope with movement as well as fire. The product and depth are chosen to suit both, following the tested detail.
Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report. Several properties can be quoted together.
We regularly work with letting and managing agents. Tell us the address, the job and how access works.
What we cannot put right
It helps to know what we can’t do too:
- Deciding what fire stopping a building needs
- Openings too large for sealant, which need batts, boards or another system
- Fire doors that need new seals, closers or hardware
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think before booking.

Leave it or put it right?
Waiting for the next refit can leave a gap open for years. On its own, sealing it now is a small job that doesn’t depend on other work. Around Bonhill, water from a failed joint in an older stone home can soak into timber and plaster.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Bonhill: your questions answered
Is Bonhill within the area you cover?
Yes, Bonhill is covered. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Alexandria station?
Yes, rental work is part of what we do. You can email us at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before work begins.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
What fire rating will the seal have?
Ratings and certificates aren’t something we issue. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves, and we install to them.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Is there a guarantee?
Yes, for a year. If there’s a problem with our work in that time, tell us and we’ll put it right.
Do you do fire sealant around door frames?
Yes. We seal the gap between the frame and the wall with a suitable fire-rated product. The door leaf and its hardware need a door specialist.
Do you carry out fire risk assessments?
No, we don’t assess buildings. Once you have a specification or action list from your assessor or designer, we’ll quote for the sealant work on it.
What affects the quote in Bonhill
We do not publish a price list. The quote depends on:
- How much old sealant there is and how hard it is to remove
- The amount of work
- How many rooms, windows or areas are involved
- The type of sealant required
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we will explain what it covers.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Access, such as stairs, a lift or height
- The rough size of the job
- Where the property is
- Whether it has been sealed before
Getting a quote is simple: let us know what needs doing and where. Photos by email help us understand the job, and we’ll take it from there.
