- Open holes round services passing through fire walls
- Fire seals that have cracked with movement
- Joints picked up in a fire-stopping survey
Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
How we handle fire rated sealant in St Paul's Cray
Until it’s heated, intumescent sealant behaves like an ordinary sealant; in a fire it expands into the joint. The right product depends on the gap size, the substrate and what passes through, so we follow the tested detail for each one. Common call-outs are for sealant items on a fire risk assessment action list and holes left by a change of layout, across service penetrations, pipe & cable gaps and door frames.
Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. Timings and access are agreed with the building before work starts in St Paul's Cray.
Every job is covered by a one-year guarantee.

Do you need fire rated sealant in St Paul's Cray?
A lot of fire stopping is out of sight: above ceilings, inside risers and behind panels. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.
Common reasons people contact us include:
- Open holes round services passing through fire walls
- Gaps filled with a product that is not fire-rated
- New service routes left unsealed after building work
- Fire seals that have cracked with movement
As a London address, St Paul's Cray can be tricky for parking: let us know about parking bays, permits or a driveway.

What fire rated sealant looks like in St Paul's Cray
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. Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed.
If you look after a church, hall or community building such as St Barnabas, service openings in its walls need the right fire-rated sealant, as in any building. Schools such as Leesons Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.

Surface by surface
Door frames
We deal with the gap around the frame, not the door. The door leaf, its seals and closer need a door specialist and we will mention anything we notice.
Linear gaps
Linear gaps run along the head of walls, at floor edges and between panels. We seal them to the tested detail, with backing where it’s needed.

Common questions in St Paul's Cray
Do you work for landlords with property near St Mary Cray station?
Yes, rental work is part of what we do. You can phone 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 you cover St Paul's Cray for fire rated sealant?
Yes. Our work covers London and the South East, and St Paul's Cray is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job.
Can you tell me how many minutes the seal will last?
We do not give ratings or certificates for our work. 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.
What’s the difference between intumescent and fire-rated sealant?
Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent ones swell in heat, and they’re one of the options. We use whichever the specification and tested details call for.
Do you provide details of the products used?
Yes. We note each location and the product that went in.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Keep the record of products and locations with your fire safety documents
- Ask which product was used before you paint
- Keep photos of seals that will be hidden
- Never patch a fire seal with standard sealant
Leave the sealant to cure fully before painting near it. Not every fire-rated sealant takes paint and we will tell you which one you have.
A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded so you can show it was dealt with.
Why act early in St Paul's Cray
Sealant is not the fix for every opening. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. If a gap isn’t suitable for sealant, we’ll tell you. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in St Paul's Cray, the repair is bigger than a sealant job.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Why book with us
- Neat joints and a tidy finish
- 4.9 on Google from 180+ five-star reviews
- Anti-fungal silicone where joints get wet
- Any old sealant cut out fully, not covered over

How the visit works
You don’t need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the job takes anything from a few hours to several days, depending on how many gaps there are in most cases. In St Paul's Cray, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- Each gap is measured and its substrate and service noted.
- Any non-fire-rated filler is removed and the faces cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- We hand over a list of locations and products for your files.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Clear items away from the joints we are working on
- Keep pets and children clear of the area while we work
