Fire rated sealant in Hartley, 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 door frames, plasterboard & masonry and pipe & cable gaps, and the jobs we see most are gaps flagged on a fire risk assessment and cracked or shrunken fire-rated sealant.
Work in a small place like Hartley is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.
Whatever the size of the job, it’s backed by our one-year guarantee in Hartley and across Kent.

Why deal with it now?
Fire-rated sealants need more care than everyday sealant. Depth, backing and surface preparation all affect how a seal performs, and we work to the product details every time. Around Hartley, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What happens on the day
There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the work takes from a few hours to a few days, depending on the number of gaps and the access for a typical job. Somewhere like Hartley needs a little journey planning: 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.
- 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.
- Unsuitable material such as ordinary foam or silicone is cut out and the gap cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used for your files.
Before we arrive
- Let us know about parking restrictions
- Plan for the work area to be out of bounds to pets and children
- Mention any tricky access

- Whether the work is at height
- When we can work, for business premises

Surface by surface
Linear gaps
Some linear gaps have to cope with movement as well as fire. We choose a product and depth that suit the gap and the movement, following the tested detail.
Service penetrations
Different services need different details: metal pipes, cables and plastic pipes are not treated the same. Each one is sealed to the product’s tested detail.

Do you do fire sealant around door frames?

Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Common problems we fix in Hartley
Gaps around door frames are easily missed. The architrave hides the gap between frame and wall, so it’s easy to leave unsealed when doors are changed.
Look out for any of the following:
- Gaps left after a refit or conversion
- Damaged fire sealant left by other trades
- Ordinary sealant used where a fire-rated product was needed
- Door frames with gaps between frame and wall
For site and facilities teams at buildings such as High Weald Academy, gaps opened by contractors for new cabling are a common finding in schools and offices.
What to look for in a quote
- Is VAT in the price?
- Is the old sealant removed completely?
- How hidden problems are handled
- How much experience the applicator has
When it isn’t the sealant
We’ll always be straight with you, so here’s what new sealant will not do:
- Large holes that need a different fire-stopping system
- Problems with the door itself rather than the gap around the frame
- Assessing a building’s fire safety
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think before booking.
