Headcorn Fire Rated Sealant
We cover Headcorn for intumescent and fire-rated sealant around gaps, frames and service penetrations. Old sealant removed completely, joints prepared properly.
- Gaps around pipes and cables through fire-resisting walls
- Fire stopping disturbed by later work
- Sealant items on a fire risk assessment action list
Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Fire rated sealant in Headcorn, done properly
Landlords, managing agents and facilities teams use us for the sealant items on a fire risk assessment. If you share the list, we can quote for the gaps that need fire-rated sealant. Common call-outs are for gaps left after a refit or conversion and sealant items on a fire risk assessment action list, across pipe & cable gaps, door frames and service penetrations.
If you run a pub, café, guest house or shop in or near Headcorn, the washrooms and kitchen need the same attention as a big site, and fire-rated sealant around service openings should be restored after new pipes or cables go through.
Every job comes with a one-year guarantee, wherever you are in Kent.

Why act early in Headcorn
An unsealed gap lets smoke and fire get round a wall that was built to hold them back. Sealing it properly restores what the wall was there to do, and the sealing itself is often a contained piece of work. Around Headcorn, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
What you pay reflects the work, not guesswork. That is why we ask about the job first and give you a clear quote before any work starts.

Workplaces and buildings in Headcorn
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.
If you let a flat or house near Headcorn station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. Community buildings like St Peter's and St Paul's Church are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

The process
There is not much for you to do on the day. Show us the job and we’ll take it from there. The work itself takes from a few hours to a few days, depending on the number of gaps and the access from start to finish. In a smaller place like Headcorn, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- Access to each area is agreed so the work can run in order.
- Old, damaged or unsuitable sealant is removed.
- Gaps are cleaned of dust and loose material.
- We apply and tool the sealant to the product’s tested detail.
- We record what was done and flag anything that needs a different system.
Before we arrive
- Mention if the joints have been sealed before
- Keep children and pets away from the work area
- Clear items away from the joints we are working on
Ask for a quote

Related advice
When to call us in Headcorn
Lots of unsealed gaps appear long after the building was completed. New cables, pipes and data runs go through walls and ceilings and the hole they leave doesn’t always get resealed.
Signs it’s time to call us include:
- Joints picked up in a fire-stopping survey
- Seals cut through by electricians, plumbers or data installers
- Open joints along the top of partitions
- Door frames with gaps between frame and wall
Schools such as Headcorn Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.

What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Deciding what fire stopping a building needs
- Large holes that need a different fire-stopping system
- Construction that doesn’t provide fire resistance on its own
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly before booking.

How we quote for fire rated sealant

What we need to know
To help us quote quickly, let us know:
- Whether it has been sealed before
- Roughly how big the job is
- How we’d reach the joints
- The type of property
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. When it suits you, phone 0345 464 0079 or email us.
