About our fire rated sealant in Longlands
We do not assess buildings or decide what fire stopping is needed; that comes from your fire risk assessor, designer or building control. What we do is apply the right product to that specification, properly and neatly. We work on plasterboard & masonry, pipe & cable gaps and linear gaps, and people most often call us about gaps flagged on a fire risk assessment and open joints along the top of partitions.
London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, whether that is washroom resealing or fire-rated sealant around service openings. Out-of-hours working can be arranged where a building in Longlands can’t close.
You’re covered for a year from the day we finish. If anything isn’t right with it, ring 0345 464 0079 or send us an email.

What we are called out for in Longlands
A lot of fire stopping is out of sight: above ceilings, inside risers and behind panels. Out of view, damage sits unnoticed until someone inspects.
Look out for these signs:
- Unsealed gaps around fire door frames
- Fire seals that have cracked with movement
- Gaps around pipes and cables through fire-resisting walls
- Standard silicone or caulk in a fire-stopping gap
If you look after a church, hall or community building such as Christ Church, older buildings that have had new heating or wiring often have service gaps worth checking.
Questions to ask before booking
- How long the guarantee is
- What insurance they hold
- Is the old sealant removed completely?
- Which colour the sealant will be

Fire rated sealant around Longlands
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, which is often where open fire-stopping gaps are first noticed. We work to the specification you are given, installing the product to its tested details. Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange.
As a London address, Longlands can be tricky for parking: let us know about parking bays, permits or a driveway. For landlords with property near New Eltham station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

How the job changes by surface
Service penetrations

Plasterboard walls
Plasterboard partitions are common in flats, offices and conversions. The sealant has to be one tested in plasterboard.
Longlands questions
Can you help a landlord with a rental near New Eltham station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.
Is Longlands in your area for fire rated sealant?
Yes, Longlands is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing.
Can I use normal mastic around a pipe through a fire wall?
No. A gap that needs fire stopping needs a tested fire-rated product.
Can you give us a record of the work?
Yes. Locations and products are written up when we finish. If you need photos or a set layout, ask when you get a quote.
Can you tell me how many minutes the seal will last?
We don’t issue ratings or certificates ourselves. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves, and we install to them.
Can you seal over the old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all.
Do you do fire sealant around door frames?
Yes, where the gap suits a sealant detail. Our work is the gap around the frame.
DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What affects the cost of fire rated sealant
We do not publish a price list, because jobs vary so much. What we look at:
- The number of rooms or windows
- How easy the joints are to reach
- Whether there’s mould to deal with
- Any working-time requirements on site
Combining jobs into one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We’ll give you a clear price for the lot.
Helping us quote
When you contact us, it’s useful to know:
- The type of property
- The problem you’ve noticed
- Pictures of the joints, sent by email
- How many joints, rooms or windows are involved
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is.
What happens on the day
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes from a few hours to a few days, depending on the number of gaps and the access, including the tidy-up. For a job in Longlands, parking and access are the things to plan: let us know about parking, the floor we will be working on and any lift or shared entrance.
- 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 faces cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used for your records.
How to prepare
- Let us know about stairs, lifts or work at height
- Where the joints are inside, avoid wetting them before we arrive
- Mention any parking rules near the property
