Fire Rated Sealant in Bighton
Problem with your fire-stopping gaps in Bighton? We cut out the old, prepare the joints and apply the right sealant, with a one-year guarantee.

How we handle fire rated sealant in Bighton
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 follow the tested detail for each one. We’re often asked to deal with gaps around pipes and cables through fire-resisting walls and seals cut through by electricians, plumbers or data installers, on door frames, flats & HMOs and pipe & cable gaps.
If you have holiday lets, a converted barn used for business or a community building near Bighton, 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, in Bighton and everywhere else we cover.

Workplaces and buildings in Bighton
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.
If you look after a building such as Perins School, service openings in fire-resisting walls need checking after any refurbishment.

Common problems we fix in Bighton
Much fire stopping is hidden: in ceiling voids, service risers and behind boxing. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.
These are the problems we’re asked about most:
- Unsealed gaps where pipes and cables go through a wall
- Standard silicone or caulk in a fire-stopping gap
- Sealant items on a fire risk assessment action list
- Fire stopping disturbed by later work
Community buildings like Church of All Saints are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

- Whether all the old sealant comes out first
- Whether they’re fully insured
Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Plan fire stopping into any work that goes through walls or floors
- Do not paint over fire sealant until it has cured
- Keep photos of seals that will be hidden
- Look in service cupboards and ceiling voids from time to time
Include fire stopping in your regular building checks. Watch for cracking, gaps or seals that have been disturbed and have them put right.
Any job that breaks through a wall or ceiling should include resealing. Catching it then saves a separate visit later.
The process
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes anything from a few hours to several days, depending on how many gaps there are from start to finish. In a small place like Bighton, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Before starting, we go through the specification or action list with you.
- We measure every gap and note what it’s in and what passes through.
- Any non-fire-rated filler is removed.
- We fit backing where needed and apply the fire-rated sealant to depth.
- We hand over a list of locations and products.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Let us know about parking restrictions
- Tell us about any previous sealing or DIY attempts
Ask for a quote
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.

Honest limits
To be straight with you, there are a few things sealant will not fix:
- Sign-off of the building, which sits with building control or your assessor
- Problems with the door itself rather than the gap around the frame
- A wall that is not a fire-resisting element to begin with
If you are not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.
What we seal

DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

Ratings and certificates are not something we issue. The performance comes from the product’s tested details and the specification from your assessor or designer, and we install to them.
What does intumescent mean?
An intumescent material expands when it’s heated. Many fire-rated sealants work this way, but not all.

Different surfaces, different methods
Door frames
Frame gaps are usually hidden behind the architrave. We seal any open gap to the product’s tested details so the architrave can be refitted.
Masonry and concrete
Preparation counts on brick, block and concrete. The gap is cleaned and backed where required.
