Fire rated sealant for homes and businesses in Lullingstone
Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. Each gap is sealed to the product maker’s tested detail for its size and substrate, with a record of the products and locations if you need one. If you’re dealing with door frames with gaps between frame and wall and fire seals that have cracked with movement, we can put it right, on plasterboard & masonry, service penetrations and linear gaps alike.
For a small place like Lullingstone, the journey and timings are agreed in advance, so it can be fitted around guests, clients or events where possible.
There’s a 12-month guarantee on every job, large or small.

Honest limits
Sealant is not the answer to every problem, and we will tell you before any work starts. Sealant won’t put right:
- Construction that does not provide fire resistance on its own
- Issuing a fire rating or certificate for a building
- Doors that are not fire doors in the first place
If you’re not sure, just call 0345 464 0079 or email us and we will give you a straight answer before you book.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
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, and the work is guaranteed for a year.
What the job involves on each surface
Flats and HMOs
Conversions usually leave a mix of old and new service holes. We seal the ones on your specification with a tested product and the locations noted.
Plasterboard walls
We check that the board around the gap is sound. Loose material is removed so the sealant has a firm edge.
What fire rated sealant looks like in Lullingstone
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.
For buildings such as Church of Saint Botolph, gaps around pipes and cables are worth checking after any building work there.

Common questions in Lullingstone
Is Lullingstone in your area for fire rated sealant?
Yes. Our work covers London and the South East, and Lullingstone is part of that. You can ring 0345 464 0079 or email us and tell us what needs doing, and we will give you a clear price.
Is Lullingstone within the area you cover?
Yes, Lullingstone is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is it messy?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
Do you guarantee your work?
Yes. Every job comes with a one-year guarantee.
What does fire rated sealant cost?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Do you take out the old sealant first?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Can you seal over the old sealant?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
Can I use normal mastic around a pipe through a fire wall?
No. Where a fire-rated seal is needed, it has to be a product tested for that use, installed to its details.
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Keep photos of seals that will be hidden
- Get damaged fire seals looked at promptly
- Ask every contractor to reseal any fire stopping they disturb
- Check risers, ceiling voids and cupboards during building checks
Include fire stopping in your regular building checks. Look for cracks, gaps or sealant that has been cut or pulled out and have them put right.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Sealing it early is a simple step to take.
What we’re called out for in Lullingstone
Sealant applied too thin, without the backing its detail needs, or onto dust will not perform as it was tested. Rushed fire stopping is common particularly when it was the last job before handover.
Look out for any of the following:
- Fire stopping disturbed by later work
- Fire seals that have cracked with movement
- Door frames with gaps between frame and wall
- Gaps where walls meet ceilings or slabs
Rented homes near Eynsford station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Why it’s worth doing now in Lullingstone
Items left open on a fire risk assessment tend to come back at the next review. Getting them done and written up gives you evidence that the item was dealt with. Around Lullingstone, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
