Fire rated sealant in Camberwell
Landlords, managing agents and facilities teams use us for the sealant items on a fire risk assessment for buildings in Camberwell. If you share the list, we can quote for the gaps that need fire-rated sealant. We work on flats & HMOs, pipe & cable gaps and door frames, and the jobs we see most are joints picked up in a fire-stopping survey and unsealed gaps where pipes and cables go through a wall.
In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. For managing agents and building owners in Camberwell, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.
Whatever the size of the job, you get the same 12-month guarantee in Camberwell and across Greater London.

What affects the quote in Camberwell
Your quote is based on your job. We look at:
- The old material and how stubborn it is
- Mould in or behind the old joints
- The product the joint needs
- Access and height
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Where the job is, and your postcode
- Roughly how big the job is
- What the problem is, such as mould, gaps, leaks or cracking
- Photos by email, if that is easy
For a quick quote, get us on the phone, or email us if that’s easier. Tell us about the joints that need doing and we’ll talk you through the work.
Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Photograph sealed gaps before they’re covered up
- File the fire-stopping record where your assessor can find it
- Get damaged fire seals looked at promptly
- Check whether a sealant can be painted before decorating over it
Include fire stopping in your regular building checks. Watch for cracking, gaps or seals that have been disturbed and get them seen to.
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.
How it works
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the job takes from a few hours to a few days, depending on the number of gaps and the access in most cases. In Camberwell, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- Before starting, we go through the specification or action list with you.
- Each gap is measured and its substrate and service noted.
- Unsuitable material such as ordinary foam or silicone is cut out.
- The specified fire-rated sealant goes in over any backing its detail requires.
- We hand over a list of locations and products for your files.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Clear the area around the work
- On commercial sites, let us know about site rules
How to get a quote
Getting a quote is simple: tell us what needs doing and where. Photos by email help us understand the job, and we will take it from there.

Fire rated sealant in Camberwell: local notes
Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange. 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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Managing a site like Mary Datchelor School? Then service openings in fire-resisting walls need checking after any refurbishment. Community buildings like St Giles' Church are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building. If you let a flat or house near Denmark Hill station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
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, then guaranteed for a year.

Why act early in Camberwell
Squirting in whichever sealant is nearest does not make a fire seal. A fire-rated product only performs as tested when it’s installed to its tested detail, so both the product and the method matter. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.

Camberwell: your questions answered
Can you help a landlord with a rental near Denmark Hill station?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or drop us an email and tell us about the property, and we’ll send you a clear quote.
Is parking a problem for a job in Camberwell?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Do you certify the fire stopping?
That is not something we state or certify. The requirement comes from your assessor, designer or building control, and we fit a product whose tested details meet it with a record of each location.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and you will get one quote.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Do you have insurance?
Yes, we’re fully insured for domestic and commercial work.
Will there be a smell?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
