Fire rated sealant in Northfleet Green
Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap, with a record of the products and locations if you need one. If you’re dealing with linear gaps at the head of walls and cracked or shrunken fire-rated sealant, we can put it right, on service penetrations, flats & HMOs and door frames alike.
If you have holiday lets, a converted barn used for business or a community building near Northfleet Green, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
Each job carries a 12-month guarantee, large or small.

Honest limits
We won’t take on work that won’t last, so these are the limits:
- Fire risk assessments, which need a qualified assessor
- Large holes that need a different fire-stopping system
- A wall that is not a fire-resisting element to begin with
If you’re not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer.
Surfaces we seal
- Door frames
- Service penetrations
- Plasterboard & masonry
- Linear gaps
- Flats & HMOs
- Pipe & cable gaps
How the job changes by surface
Masonry and concrete
Preparation counts on brick, block and concrete. The gap is cleaned and backed where required before the sealant goes in.
Door frames
We deal with the gap around the frame, not the door. Doors, seals and closers are for a door specialist, and we’ll say if we spot a problem with them.

Northfleet Green: your questions answered
I let a flat near Ebbsfleet International station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before we start.
Is Northfleet Green in your area for fire rated sealant?

Can I choose the sealant colour?
Most of the time, yes. We will explain which colours are available and agree one before work begins.
Are you insured?
Yes. We are fully insured, and we can confirm the details when we quote.
How long will you be here?
That depends on how much there is to do, but most jobs take a few hours for a handful of gaps, and longer for a whole building. We will tell you when we quote.
Can ordinary silicone be used in a fire-stopping gap?
No. It looks sealed but won’t perform as fire stopping. A tested fire-rated product is needed.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Where are you based?
Our base is in Crawley, and we work across South East England, London and Scotland.

If you let a flat or house near Ebbsfleet International station, any gap left by new services in shared walls should be closed with a fire-rated product. For buildings such as Church of St Nicholas, gaps around pipes and cables are worth checking after any building work there.

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What we are called out for in Northfleet Green
Many open fire-stopping gaps are made after the building is finished. New cables, pipes and data runs go through walls and ceilings and the hole they leave does not always get resealed.
Any of these means the joints need attention:
- Joints picked up in a fire-stopping survey
- Fire stopping disturbed by later work
- New service routes left unsealed after building work
- Door frames with gaps between frame and wall
Managing a site like Painters Ash Primary School? Then gaps opened by contractors for new cabling are a common finding in schools and offices.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Make resealing part of every contractor’s brief
- Store the list of sealed gaps with your building paperwork
- Keep photos of seals that will be hidden
- Do not fill fire-stopping gaps with ordinary foam or silicone
Avoid covering a sealed gap with anything that isn’t part of the tested detail. Repairs should use a matching fire-rated product. We can tell you which product we used.
If a fire risk assessment has flagged a gap, do not leave it for the next one. Have it sealed, then keep the record.
