What fire rated sealant looks like in Gustard Wood
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, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
For site and facilities teams at buildings such as St Helen's Church of England Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices. If you look after a church, hall or community building such as St Peter, service openings in its walls need the right fire-rated sealant, as in any building.

Signs you need fire rated sealant in Gustard Wood
A lot of fire stopping is out of sight: in ceiling voids, service risers and behind boxing. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.
It’s worth asking for a quote if you see:
- Cracked or shrunken fire-rated sealant
- Sealant items on a fire risk assessment action list
- Damaged fire sealant left by other trades
- Open holes round services passing through fire walls
For landlords with property near Harpenden station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
Questions to ask before booking
- Is the old sealant removed completely?
- How the surfaces are prepared before sealing
- How long to leave it before use
- Whether you can choose the colour
Gustard Wood questions
I let a flat near Harpenden station. Can you help?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
Is Gustard Wood within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Can I add another job to the visit?
Yes. Just list everything you need and you’ll get one quote.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
What does intumescent mean?
Intumescent means it swells when heated. It’s one type of fire-rated sealant; the right one depends on the gap and what passes through it.
How much does fire rated sealant cost in Gustard Wood?
It depends on the job, so we quote each one individually. For a quick quote, ring 0345 464 0079 or send us an email with a short description of the job.
Why it’s worth doing now in Gustard Wood
Doing it once, properly, beats doing it twice. Work that does not follow the tested detail may have to come out again once someone inspects it. Older cottages and farmhouses around Gustard Wood can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear quote for the lot.
What you get with us
- A 12-month guarantee on all work
- Anti-fungal sanitary silicone in wet areas
- Full insurance on every job
- Any old sealant cut out fully, not covered over

DIY sealant or a professional job?
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.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Keep the record of products and locations with your fire safety documents
- Include fire stopping when you schedule refits
- Look in service cupboards and ceiling voids from time to time
- Ask every contractor to reseal any fire stopping they disturb
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.
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.
