About our fire rated sealant in Dunoon
Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. Each gap is sealed to the product maker’s tested detail for its size and substrate, and we can record what went where. We work on pipe & cable gaps, door frames and flats & HMOs, and common reasons people get in touch are cracked or shrunken fire-rated sealant and linear gaps at the head of walls.
For holiday lets, guest houses and community buildings in or near Dunoon, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
A one-year guarantee comes with the work, just as it does everywhere we cover.

FAQs for Dunoon
Will you come out to Dunoon?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Do you work for hotels and guest houses in Dunoon?
Yes, hospitality work, including hotels, is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Do you carry out fire risk assessments?
No. That is for a fire risk assessor, designer or building control. Our job is applying the sealant to their specification.
What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we are using and why.
How much does fire rated sealant cost in Dunoon?
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 we do, step by step
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. It generally takes from a few hours to a few days, depending on the number of gaps and the access. Around Dunoon, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We plan the order of work and access, floor by floor or flat by flat.
- Old, damaged or unsuitable sealant is removed.
- 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
- Clear items away from the joints we are working on
- Tell us about access, such as stairs, a lift or high-level joints
- Where the joints are inside, avoid wetting them before we arrive

Workplaces and buildings in Dunoon
If you run a hotel, guest house or holiday let in a coastal place like Dunoon, 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. In Scotland, building work comes under the Building (Scotland) Regulations and their technical handbooks. We install fire-rated sealant to the product’s tested details; we don’t certify buildings or carry out fire risk assessments.
Letting a property close to Inverkip station? Then any gap left by new services in shared walls should be closed with a fire-rated product. If you look after a building such as Dunoon Primary School And Janitor's House, gaps opened by contractors for new cabling are a common finding in schools and offices.

Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Signs you need fire rated sealant in Dunoon
Over time, buildings change layout and use. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.
Most people get in touch when they notice one of these:
- Open joints along the top of partitions
- Joints picked up in a fire-stopping survey
- Seals cut through by electricians, plumbers or data installers
- Standard silicone or caulk in a fire-stopping gap
For buildings such as St John’s Church (Dunoon), older buildings that have had new heating or wiring often have service gaps worth checking.
Before you book anyone
- What the cure time is
- The length of the guarantee
- Whether they’re fully insured
- Whether all the old sealant comes out first
What happens if it’s left?
Items left open on a fire risk assessment tend to come back at the next review. Getting them done and written up gives you evidence that the item was dealt with. In a place like Dunoon, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.
Why book with us

- Neat joints and a tidy finish

Aftercare tips
To keep the joints looking good and working properly:
- Get damaged fire seals looked at promptly
- Photograph sealed gaps before they’re covered up
- Allow for resealing whenever new services are run
- Check whether a sealant can be painted before decorating over it
Tell other trades that the gaps have been sealed, and make sure anything they disturb is resealed with a suitable product. Later work is a common cause of damaged fire stopping.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Catching it then saves a separate visit later.
