- Damaged fire sealant left by other trades
- Open joints along the top of partitions
- Fire seals that have cracked with movement
How to look after the new joints
A little care helps the new joints last. Our advice:
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Keep pictures of seals that will be hidden
- Ask which product was used before you paint
- Include fire stopping when you schedule refits
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.
A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded so you can show it was dealt with.
How we handle fire rated sealant in Blendon
Deciding which gaps need fire stopping isn’t our role; your assessor, designer or building control sets that out. Our part is applying the specified sealant carefully, to the right depth and with the right backing. We work on pipe & cable gaps, linear gaps and door frames, and people most often call us about holes left by a change of layout and door frames with gaps between frame and wall.
Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, from washroom silicone to fire-rated sealant around pipes and cables passing through walls. Out-of-hours working can be arranged where a building in Blendon cannot close.
You’re covered for a year from the day we finish. If anything is not right with it, ring 0345 464 0079 or drop us an email.

Fire rated sealant in Blendon: local notes
Blendon has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange.
Community buildings like St James the Great are part of the picture too: gaps around pipes and cables are worth checking after any building work there. Blendon is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
Blendon is about 1 mile south-east of Welling, in Greater London. Blendon gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. 764 places in Greater London are on our list, large and small.

What the job involves on each surface
Door frames
A door can only do its job if the gap behind its frame is sealed too. We seal that gap with a fire-rated sealant suited to the frame and wall.
Flats and HMOs
Flats and HMOs rely on fire separation between homes and the common parts. We seal the gaps your assessor has identified.
Can I do it myself?
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Questions from Blendon
Is parking a problem for a job in Blendon?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Do you work for hotels and guest houses in Blendon?
Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
What does intumescent mean?
Intumescent means it swells when heated, helping close the gap. It’s one type of fire-rated sealant; which product suits depends on the gap, the substrate and the service.
Is there a guarantee?
Yes, always. There’s a 12-month guarantee on every job.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Do the sealants smell?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
Do you need fire rated sealant in Blendon?
Much fire stopping is hidden: above ceilings, inside risers and behind panels. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.
The most common problems we see are:
- Open holes round services passing through fire walls
- Fire stopping disturbed by later work
- Ordinary sealant used where a fire-rated product was needed
- Joints picked up in a fire-stopping survey
Letting a property close to Albany Park station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
What to look for in a quote
- Is VAT in the price?

What affects the quote in Blendon
Your quote is based on your job. We look at:
- Working hours on commercial sites
- The amount of work
- The old material and how stubborn it is
- How many rooms, windows or areas are involved
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.
Asking for a quote
To make quoting easier, please include:
- Access, such as stairs, a lift or height
- The problem you’ve noticed
- Roughly how big the job is
- Any previous sealing or DIY work
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
How the visit works
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the job takes anything from a few hours to several days, depending on how many gaps there are in most cases. In Blendon, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- Old or unsuitable sealant is cut out and the gap cleaned.
- Backing or fill is fitted where the product’s tested detail calls for it.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- Finally, we list where we worked and what we used, for your records.
How to prepare
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we are working on
- Let us know about stairs, lifts or work at height
