Fire rated sealant for homes and businesses in Crockleford Heath
A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. We check the size and the substrate before choosing the product, then apply it to the depth its tested detail calls for. Typical jobs include fire seals that have cracked with movement and holes left by a change of layout, on plasterboard & masonry, flats & HMOs and door frames.
If you have holiday lets, a converted barn used for business or a community building near Crockleford Heath, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Fire rated sealant around Crockleford Heath
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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 Colchester Academy, service openings in fire-resisting walls need checking after any refurbishment.

Leave it or put it right?
Fire-rated sealants are less forgiving than ordinary ones. Depth, backing and surface preparation all affect how a seal performs, so we follow the maker’s details on every gap. Where a wall is exposed, as many are in small places like Crockleford Heath, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Call for a quick quote and we will explain what it covers.

Related advice
Aftercare tips
A little care helps the new joints last. We recommend:
- Check risers, ceiling voids and cupboards during building checks
- Photograph sealed gaps before they’re covered up
- Make resealing part of every contractor’s brief
- Get damaged fire seals looked at promptly
Include fire stopping in your regular building checks. Look for cracks, gaps or sealant that has been cut or pulled out and get them seen to.
It’s easiest to seal gaps while they’re few and easy to reach. Over time, more work adds more holes and the job gets bigger.
What we cannot put right
Before you book, it’s worth knowing the limits too:
- Openings too large for sealant, which need batts, boards or another system
- Certifying a building or signing off its fire safety
- Fire risk assessments, which need a qualified assessor
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.
What we seal
- Service penetrations

Do you seal gaps around fire door frames?
Yes. We often seal open gaps hidden behind the architrave. Doors, seals and closers need a door specialist.
How long does fire rated sealant take?
That depends on the amount of work, but as a guide it takes a few hours for a handful of gaps, and longer for a whole building. We will give you a better idea when we quote.
Will we have a record of what was sealed?
Yes. We note each location and the product that went in so it’s there for the next inspection.
Is the work guaranteed?
Yes. Every job comes with a 12-month guarantee.
Is it messy?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
What’s the difference between intumescent and fire-rated sealant?
An intumescent sealant expands when it gets hot to help seal the gap. Intumescent sealants are one kind of fire-rated sealant; the right one depends on the gap and what passes through it.
Common problems we fix in Crockleford Heath
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.
It’s worth asking for a quote if you see:
- Gaps around pipes and cables through fire-resisting walls
- Sealant items on a fire risk assessment action list
- Fire stopping disturbed by later work
- New service routes left unsealed after building work
For landlords with property near Hythe station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

How the job changes by surface
Masonry and concrete
Masonry is dusty and porous, so preparation matters. We brush and vacuum the gap and use backing where the detail needs it before the sealant goes in.
Door frames
Frame gaps are usually hidden behind the architrave. Where it’s open, we seal it to the product’s details for that gap size before the trim goes back.
