Fire rated sealant around Little Chalfont
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 work to the specification you’re given, installing the product to its tested details.
For site and facilities teams at buildings such as Dr Challoner's High School, gaps opened by contractors for new cabling are a common finding in schools and offices. For landlords with property near Chalfont & Latimer station, any gap left by new services in shared walls should be closed with a fire-rated product.

About our fire rated sealant in Little Chalfont
Intumescent sealant looks much like any other sealant until it gets hot; then it swells to help close the gap. 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 service penetrations, plasterboard & masonry and linear gaps, and common reasons people get in touch are sealant items on a fire risk assessment action list and holes left by a change of layout.
Commercial work around a smaller place like Little Chalfont generally means a pub, a shop, a school or small business units rather than office blocks. Each needs the same care with its sealant as any larger building.
Whatever the size of the job, you get the same 12-month guarantee.

Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
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.
What happens if it’s left?
For some gaps, sealant isn’t the right answer and another system is needed. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. If a gap is not suitable for sealant, we will tell you. Homes in smaller places like Little Chalfont can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first.
What you get with us
- Neat joints and a tidy finish
- Quality sealants from Arbo and Everbuild
- Homes, businesses and hotels
- ARBOMaster approved applicator
What happens on the day
At the end, we look at the finished work together and tell you how long to leave it. The visit itself normally takes a few hours for a handful of gaps, and longer for a whole building, depending on the size of the job. For a job in Little Chalfont, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- Anything that is not fit for the job comes out, and the gap is cleaned.
- We put in whatever backing or fill the product detail specifies.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- We record the locations and products used for your records.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Move anything stored near the joints
- For business premises, tell us about site rules or sign-in

Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Check risers, ceiling voids and cupboards during building checks
- Keep the record of products and locations with your fire safety documents
- Allow for resealing whenever new services are run
- Keep general-purpose foam and caulk away from fire-stopping gaps
Let contractors know where fire stopping has been done, 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.
What sealant work can’t fix
To be straight with you, there are a few things sealant won’t fix:
- Doors that aren’t fire doors in the first place
- Construction that does not provide fire resistance on its own
- Sign-off of the building, which sits with building control or your assessor
Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly before booking.
Surfaces we seal
- Flats & HMOs
- Plasterboard & masonry
- Door frames
- Service penetrations
- Linear gaps
- Pipe & cable gaps
When to call us in Little Chalfont
In some buildings the gap was filled with the wrong thing in the first place: ordinary expanding foam, standard silicone or decorators’ caulk where a fire-rated seal was needed. It may look fine, but it is not a fire-rated seal.
Any of these means the joints need attention:
- Gaps where walls meet ceilings or slabs
- Gaps left after a refit or conversion
- Standard silicone or caulk in a fire-stopping gap
- Cracked or shrunken fire-rated sealant
If you look after a church, hall or community building such as St George's Church, service openings in its walls need the right fire-rated sealant, as in any building.
Before you book anyone

- How the joint is cleaned and prepared

- Whether they’re fully insured

Little Chalfont questions
Is Little Chalfont within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Chalfont & Latimer station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
Can you match the sealant colour?
We will suggest a colour to suit the surroundings. The choice depends on the product the joint needs.
Can you tell me how many minutes the seal will last?
Ratings and certification sit with the product’s test evidence and whoever specified the work. Our part is installing the specified product to its tested details and giving you a record of where it went.
How long does fire rated sealant take?
It depends on the size of the job, but as a guide it takes a few hours for a handful of gaps, and longer for a whole building. We will tell you when we quote.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Do the sealants smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
