Craigends Fire Rated Sealant
Intumescent and fire-rated sealant around gaps, frames and service penetrations for householders, landlords and businesses in Craigends. ARBOMaster approved applicators, fully insured, with a 12-month guarantee.
- Gaps filled with a product that is not fire-rated
- Gaps where walls meet ceilings or slabs
- Fire seals that have cracked with movement
Why deal with it now?
Fire-rated sealants are less forgiving than ordinary ones. How it’s installed changes how it performs, so we follow the maker’s details on every gap. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.

How we handle fire rated sealant in Craigends
Intumescent sealant looks much like any other sealant until it gets hot; in a fire it expands into the joint. Which product suits a gap depends on its width, the materials either side and what runs through it, so we work to the manufacturer’s details. We work on pipe & cable gaps, service penetrations and plasterboard & masonry, and the jobs we see most are holes left by a change of layout and unsealed gaps around fire door frames.
For a place like Craigends, the journey and timings are planned in advance, so the job can fit around guests, residents or opening hours where possible.
All our work is covered by a one-year guarantee.

How to look after the new joints
Aftercare is simple:
- Take pictures of fire stopping before ceilings or boxing go back
- Include fire stopping when you schedule refits
- Check risers, ceiling voids and cupboards during building checks
- Tell trades working in the building that fire seals must be put back
Look at the sealed gaps as part of your routine walk-rounds. Watch for cracking, gaps or seals that have been disturbed and have them put right.
An open gap is not only a fire issue: noise, draughts and even pests can come through too. Sealing them early helps on every front.
Fire rated sealant in Craigends: local notes
In Scotland, building work comes under the Building (Scotland) Regulations and their technical handbooks. Fire-rated sealant is installed to the manufacturer’s tested details; we do not certify buildings or carry out fire risk assessments.
Community buildings like St Fillan's R.C. Church and School are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking. If you look after a building such as Gryffe High School, service openings in fire-resisting walls need checking after any refurbishment.

When it isn’t the sealant
New sealant can’t fix everything, and we will tell you before any work starts. Sealant won’t put right:
- Deciding what fire stopping a building needs
- Sign-off of the building, which sits with building control or your assessor
- Large holes that need a different fire-stopping system

DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

Related advice
What we’re called out for in Craigends
Gaps around door frames are easily missed. The architrave hides the gap between frame and wall, so it can be left open when a door is replaced.
If you can see any of these, it’s time to have the joints looked at:
- Old fire sealant that has split or come away
- Open gaps behind door architraves
- Gaps filled with a product that isn’t fire-rated
- Damaged fire sealant left by other trades
For landlords with property near Johnstone station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
