Fire rated sealant for homes and businesses in St Ibbs
Deciding which gaps need fire stopping isn’t our role; your assessor, designer or building control sets that out. What we do is apply the right product to that specification, properly and neatly. Typical jobs include holes left by a change of layout and damaged fire sealant left by other trades, across flats & HMOs, plasterboard & masonry and pipe & cable gaps.
Somewhere as small as St Ibbs, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

What we are called out for in St Ibbs
Gaps around door frames are easily missed. The architrave hides the gap between frame and wall, so it’s easy to leave unsealed when doors are changed.
It’s worth asking for a quote if you see:
- Gaps left after a refit or conversion
- Damaged fire sealant left by other trades
- Gaps filled with a product that is not fire-rated
- Sealant items on a fire risk assessment action list
If you look after a church, hall or community building such as Church of St Ippolyts (church of England), older buildings that have had new heating or wiring often have service gaps worth checking.
Questions to ask before booking
- The length of the guarantee
- Who turns up on the day
- Is VAT in the price?
- How the colour is chosen
When something else is needed
It helps to know what we cannot do too:
- Doors that are not fire doors in the first place
- Openings too large for sealant, which need batts, boards or another system
- Issuing a fire rating or certificate for a building
If you’re not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Store the list of sealed gaps with your building paperwork
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Flag any open gap you spot round a pipe or cable
- Include fire stopping when you schedule refits
Look at the sealed gaps as part of your routine walk-rounds. Watch for cracking, gaps or seals that have been disturbed and get them seen to.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Sealing it early is a simple step to take.

What do you need from me for a quote?
A short description and the location, plus photos if you have them. We’ll ask anything else we need to know.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
What does intumescent mean?
Intumescent describes a material that swells in heat. Many fire-rated sealants work this way, but not all, and the choice depends on the gap.
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, to the product’s details. The door, its seals and closer are for a door specialist.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

We’re based in Crawley, and we cover South East England, London and all of Scotland.
Commercial buildings in St Ibbs
In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
For landlords with property near Hitchin station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. If you look after a building such as St Ippolyts Church of England Aided Primary School, service openings in fire-resisting walls need checking after any refurbishment.

What we do, step by step
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes from a few hours to a few days, depending on the number of gaps and the access. For a village or hamlet like St Ibbs, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- 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 for your records.
How to prepare
- Mention if the joints have been sealed before
- Where the joints are inside, avoid wetting them before we arrive
- Let us know if you’ve seen damp or leaks

Related advice
How the job changes by surface
Masonry and concrete
Preparation counts on brick, block and concrete. We brush and vacuum the gap and use backing where the detail needs it.
Door frames
Frame gaps are generally hidden behind the architrave. We seal any open gap to the product’s tested details.
What happens if it’s left?
Fire-rated sealants are less forgiving than ordinary ones. Depth, backing and surface preparation all affect how a seal performs, and we work to the product details every time. Older cottages and farmhouses around St Ibbs can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on how much there is to do, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.
