Fire rated sealant in Catford, done properly
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. We work on service penetrations, linear gaps and door frames, and the jobs we see most are gaps filled with a product that isn’t fire-rated and seals cut through by electricians, plumbers or data installers.
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. Where a building in Catford needs to stay open, work can be planned outside normal hours.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Surface by surface
Plasterboard walls
Many fire-resisting walls in flats, offices and conversions are plasterboard. We use a product tested in that kind of wall.
Flats and HMOs
In occupied buildings, we plan the order of work with you. Access to flats and common areas is agreed in advance to keep disruption down.
When to call us in Catford
Gaps around door frames are easily missed. The architrave hides the gap between frame and wall, so it can be left open when a door is replaced.
It’s worth asking for a quote if you see:
- Open gaps behind door architraves
- Fire seals that have cracked with movement
- Gaps filled with a product that is not fire-rated
- Gaps where walls meet ceilings or slabs
Catford is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
Before you book anyone
- Whether the sealant suits the joint
- Who does the work, and how experienced they are
- What the quote includes, VAT included or not
- Is the old sealant removed completely?
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Check whether a sealant can be painted before decorating over it
- Get damaged fire seals looked at promptly
- Store the list of sealed gaps with your building paperwork
Leave the sealant to cure fully before painting near it. Not every fire-rated sealant takes paint.
An open gap isn’t only a fire issue: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.
For landlords and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Your questions about fire rated sealant in Catford
Is parking a problem for a job in Catford?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
I let a flat near Catford Bridge station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
Do I need to be at home?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll explain our choice.
Can you match the sealant colour?
Most of the time, yes. We’ll explain which colours are available and agree one before work begins.
Can you give us a record of the work?
Yes. We record the locations we have sealed and the products used.
Can you tell me how many minutes the seal will last?
Ratings and certification sit with the product’s test evidence and whoever specified the work. We apply the specified product to the manufacturer’s details and list the locations and products for you.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
What else we do in Catford
The process
All our tools and materials come with us in the van. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes anything from a few hours to several days, depending on how many gaps there are. In Catford, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- Anything that is not fit for the job comes out, and the gap is cleaned.
- Where the tested detail needs backing or fill, we fit it.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- Locations and products are noted so you have them on file.
Before we arrive
- Let us know about parking restrictions
- Tell us about any water getting in
- Keep pets and children clear of the area while we work
How to get a quote

Fire rated sealant in Catford: local notes
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 work to the specification you are given, installing the product to its tested details. Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange.
For site and facilities teams at buildings such as Holy Cross Catholic Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices. Letting a property close to Catford Bridge station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

What happens if it’s left?
Leaving a gap until a refurbishment comes round can mean years with it open. On its own, sealing it now is a small job and needn’t wait for anything else. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.
