Fire rated sealant in The Haven, done properly
Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap. We work on plasterboard & masonry, door frames and pipe & cable gaps, and common reasons people get in touch are seals cut through by electricians, plumbers or data installers and open joints along the top of partitions.
If you have holiday lets, a converted barn used for business or a community building near The Haven, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
Our work is backed for twelve months.

What we do, step by step
We keep the work tidy and contained to the joints we’re treating, so you can carry on as normal. The job usually takes anything from a few hours to several days, depending on how many gaps there are, and we tell you how long to leave it before we go. For a village or hamlet like The Haven, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- We remove any old or unsuitable filler and clean the gap.
- Where the tested detail needs backing or fill, we fit it.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- We record the locations and products used for your records.
How to prepare
- Mention if the joints have been sealed before
- Let us know if you’ve seen damp or leaks
- For business premises, tell us about site rules or sign-in

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

What the job involves on each surface
Door frames
The gap between a door frame and the wall around it needs sealing as well as the door itself. We seal that gap with a fire-rated sealant suited to the frame and wall.
Masonry and concrete
Preparation counts on brick, block and concrete. We brush and vacuum the gap and use backing where the detail needs it.

What we can’t put right
We will not take on work that will not last, so these are the limits:
- Fire risk assessments, which need a qualified assessor
- Big openings where sealant alone is not the tested solution
- Doors that are not fire doors in the first place
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think.
Joints and surfaces we work on
- Pipe & cable gaps
- Service penetrations
- Linear gaps
- Plasterboard & masonry
- Door frames
- Flats & HMOs
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- File the fire-stopping record where your assessor can find it
- Never patch a fire seal with standard sealant
- Do not paint over fire sealant until it has cured
- 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.
It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole.
