Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Check risers, ceiling voids and cupboards during building checks
- Get damaged fire seals looked at promptly
- Make resealing part of every contractor’s brief
- Check whether a sealant can be painted before decorating over it
Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some can’t.
It’s easiest to seal gaps while they’re few and easy to reach. Over time, more work adds more holes.
How we handle fire rated sealant in Kennington
Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. 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. Common call-outs are for standard silicone or caulk in a fire-stopping gap and gaps left after a refit or conversion, across pipe & cable gaps, door frames and linear gaps.
Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. For a building in Kennington, we agree timings and access before anything starts.
Each job carries a 12-month guarantee.

What we can’t put right
We won’t take on work that will not last, so these are the limits:
- Construction that doesn’t provide fire resistance on its own
- Problems with the door itself rather than the gap around the frame
- Large holes that need a different fire-stopping system
If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer.
Surfaces we seal

Your questions about fire rated sealant in Kennington
Do you work in hotels near Kennington?
Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.
Is parking a problem for a job in Kennington?
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 guarantee your work?
Yes. Each job is guaranteed for twelve months, wherever you are.
Can you give us a record of the work?
Yes. We note each location and the product that went in, so you have it on file.
Can you quote for more than one area?
Yes. Just list everything you need and you will get one quote.
How long will you be here?
As a guide, most jobs take from a few hours to a few days, depending on the number of gaps and the access. Bigger jobs take longer.
Do you remove the old sealant?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
Can you fill the gap behind a fire door frame?
Yes. We often seal open gaps hidden behind the architrave. Doors, seals and closers need a door specialist.

DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Different surfaces, different methods
Door frames
Frame gaps are normally hidden behind the architrave. We seal any open gap to the product’s tested details before the trim goes back.
Masonry and concrete
Preparation counts on brick, block and concrete. We brush and vacuum the gap and use backing where the detail needs it.
Fire rated sealant around Kennington
There are hotels and other places to stay in and around Kennington. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details.
Schools such as St Stephen's Church of England Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment. As a London address, Kennington can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

- We go through the gaps on your list or survey and check each one’s size and substrate.
- Anything that is not fit for the job comes out, and the gap is cleaned.
- We put in whatever backing or fill the product detail specifies.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- We record the locations and products used for your records.
How to prepare
- Let us know if you’ve seen damp or leaks

What we are called out for in Kennington
Over time, buildings change layout and use. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.
Keep an eye out for any of the following:
- Old fire sealant that has split or come away
- Linear gaps at the head of walls
- Unsealed gaps where pipes and cables go through a wall
- Seals cut through by electricians, plumbers or data installers
Letting a property close to Vauxhall station? Then any gap left by new services in shared walls should be closed with a fire-rated product.
