Fire rated sealant in Lissenden Gardens, done properly
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, and we can record what went where. We work on linear gaps, plasterboard & masonry and flats & HMOs, and the jobs we see most are door frames with gaps between frame and wall and standard silicone or caulk in a fire-stopping gap.
In London, a commercial job often starts with access: loading bays, building rules and lifts. For a building in Lissenden Gardens, we agree timings and access before anything starts.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Looking after it afterwards
To keep the joints looking good and working properly:
- Never patch a fire seal with standard sealant
- Do not paint over fire sealant until it has cured
- Take pictures of fire stopping before ceilings or boxing go back
- Look in service cupboards and ceiling voids from time to time
Look at the sealed gaps as part of your routine walk-rounds. Watch for cracking, gaps or seals that have been disturbed and have them put right.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is generally a straightforward job.
Questions from Lissenden Gardens
Can parking be tricky for a visit in Lissenden Gardens?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Do you take on hotel work around Lissenden Gardens?
Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Do you provide details of the products used?
Yes. Locations and products are written up when we finish. Tell us if your assessor needs it in a particular format.
Is there a guarantee?
Yes. All our work carries our 12-month guarantee.
Can you match the sealant colour?
In most cases you can choose. We’ll explain which colours are available.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Are you fully insured?
Yes. We are fully insured.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
How we quote for fire rated sealant
Call for a quick quote. What matters most is:
- Working hours on commercial sites
- Access and height
- The product the joint needs
- How much old sealant there is and how hard it is to remove
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
Asking for a quote
What to tell us when you ask for a quote:
- How we’d reach the joints
- Pictures of the joints, sent by email
- What’s wrong with the joints now
- Where the job is, and your postcode
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
Different surfaces, different methods
Flats and HMOs
Flats and HMOs rely on fire separation between homes and the common parts. We work through the gaps on your assessment room by room.
Door frames
A door can only do its job if the gap behind its frame is sealed too. We fill it with a fire-rated product suited to the materials either side.
When it isn’t the sealant
A few problems are outside what sealant work can do:
- Big openings where sealant alone isn’t the tested solution
- Assessing a building’s fire safety
- Construction that does not provide fire resistance on its own
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.

DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
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.
Fire rated sealant around Lissenden Gardens
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. Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange.
For site and facilities teams at buildings such as Parliament Hill School, gaps opened by contractors for new cabling are a common finding in schools and offices. As a London address, Lissenden Gardens can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. Letting a property close to Gospel Oak station?
