Fire rated sealant for homes and businesses in Rhu
We often work from an action list drawn up by a fire risk assessor. If you share the list, we can quote for the gaps that need fire-rated sealant. Typical jobs include unsealed gaps where pipes and cables go through a wall and gaps flagged on a fire risk assessment, on linear gaps, door frames and plasterboard & masonry.
Commercial work around smaller Scottish places tends to mean hotels, guest houses, schools and halls rather than offices. Each needs sound sealant in its washrooms and kitchens, and fire-rated joints kept in good order.
There’s a 12-month guarantee on every job, whatever its size.

Rhu: your questions answered
How do Scotland’s building regulations apply to fire-rated sealant in Rhu?
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’s how we fit it. We don’t certify buildings or do fire risk assessments; your assessor or building control can tell you what’s required.
Do you work in hotels near Rhu?
Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
I rent my home. Can I book you?
Yes. Check with your landlord; we can send the quote to them too.
What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply email us at info@mrmastic.co.uk.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
What fire rating will the seal have?
Ratings and certificates are not something we issue. The performance comes from the product’s tested details and the specification from your assessor or designer.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
How long will you be here?
As a guide, most jobs take anything from a few hours to several days, depending on how many gaps there are. Bigger jobs take longer, and we will tell you how long to expect.
What we are called out for in Rhu
Door frames are a common weak spot. The architrave hides the gap between frame and wall, so it can be left open when a door is replaced.
The problems people normally mention when they call include:
- Open gaps behind door architraves
- Gaps left after a refit or conversion
- Damaged fire sealant left by other trades
- Open holes round services passing through fire walls
Schools such as Lomond School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.
What your quote should include
- Is VAT in the price?
- What happens if the job turns out different
- How the colour is chosen
- Are they insured?
Honest limits
To be straight with you, there are a few things sealant won’t fix:
- Fire doors that need new seals, closers or hardware
- Openings too large for sealant, which need batts, boards or another system
- Issuing a fire rating or certificate for a building
If in doubt, email us at info@mrmastic.co.uk and we will say what we think.

- Pipe & cable gaps
- Flats & HMOs

Can I do it myself?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
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.
How it works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes from a few hours to a few days, depending on the number of gaps and the access, and the area is left clean. Outdoor work around Rhu depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- Access to each area is agreed so the work can run in order.
- We take out any damaged or unsuitable sealant.
- Gaps are cleaned of dust and loose material.
- 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.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Keep pets and children clear of the area while we work
- Clear items away from the joints we are working on

Advice
What affects the cost of fire rated sealant
Your quote is based on your job. We look at:
- How easy the joints are to reach
- The number of rooms or windows
- How much old sealant there is and how hard it is to remove
- The number and length of the joints
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 the work is at height. We take all of that into account in your quote.
Asking for a quote
When you call or email, it’s useful to know:
- The rough size of the job
- The problem you’ve noticed
- Where the job is, and your postcode
- A few pictures by email, if you can
It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. When it suits you, email us at info@mrmastic.co.uk.
Surface by surface
Flats and HMOs
In flats and HMOs, the walls and floors between homes and common areas need sealing where services pass through. We work through the gaps on your assessment.
Plasterboard walls
Service holes in plasterboard are often rough and oversized. Where a hole is bigger than the sealant’s tested range, it needs another approach, and we’ll tell you.

Aftercare tips
A little care helps the new joints last. We recommend:
- Flag any open gap you spot round a pipe or cable
- Store the list of sealed gaps with your building paperwork
- Tell trades working in the building that fire seals must be put back
- Check risers, ceiling voids and cupboards during building checks
Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. A lot of damaged fire stopping comes from later work.
Open gaps do not only matter in a fire: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.
