Fire rated sealant in Crofton
Ordinary silicone or decorators’ caulk in a fire-stopping gap isn’t a fire-rated seal. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. If you’re dealing with unsealed gaps around fire door frames and unsealed gaps where pipes and cables go through a wall, we can put it right.
Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, whether that is washroom resealing or fire-rated sealant around service openings. Out-of-hours working can be arranged where a building in Crofton can’t close.
You’re covered for a year from the day we finish. If anything is not right with it, phone 0345 464 0079 or drop us an email.

Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Get damaged fire seals looked at promptly
- Tell trades working in the building that fire seals must be put back
- Include fire stopping when you schedule refits
- Ask which product was used before you paint
Leave the sealant to cure fully before painting near it. Some fire-rated sealants can be painted and some cannot and we will tell you which one you have.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is generally a straightforward job.
Landlords, agents and businesses in Crofton
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can be quoted together.
Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
Leave it or put it right?
An open gap in a fire-resisting wall is a route for smoke and fire. Sealing it properly restores what the wall was there to do, and the work involved is often modest. 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 for homes in Crofton.

Questions from Crofton
I let a flat near Orpington station. Can you help?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Can you do fire rated sealant in Crofton?
Yes. We work across London and the South East, and Crofton is part of that. You can ring 0345 464 0079 or email us and tell us what needs doing, and we will give you a clear quote.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
What fire rating will the seal have?
That is not something we state or certify. The requirement comes from your assessor, designer or building control, and we apply a product tested for it.
Can you fill the gap behind a fire door frame?
Yes, where the gap suits a sealant detail. Our work is the gap around the frame.
What does fire rated sealant cost?
It depends on the job, so we quote each one individually. For a quick quote, call 0345 464 0079 or send us an email and let us know what needs doing and where.
Can ordinary silicone be used in a fire-stopping gap?
No. Standard sealants aren’t made or tested to stop fire. We cut it out and reseal with a fire-rated product.
Will you assess my building’s fire safety?
No. We work from the specification you give us and install to the manufacturer’s details.
Can I do it myself?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
If you’re set on DIY, put the effort into 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.
Common problems we fix in Crofton
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.
The most common problems we see are:
- Open gaps behind door architraves
- Gaps where walls meet ceilings or slabs
- Fire seals that have cracked with movement
- Ordinary sealant used where a fire-rated product was needed
Crofton is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
Questions to ask before you book
- Whether the sealant suits the joint
- How long to leave it before use
- Whether VAT is included
- What happens if they find a problem under the old sealant
How it works
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a handful of gaps, and longer for a whole building. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Crofton. 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.
- We measure every gap and note what it’s in and what passes through.
- 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
- Plan for the work area to be out of bounds to pets and children
- Let us know if you’ve seen damp or leaks
- Let us know about parking restrictions
