About our fire stopping in Chelwood Gate
Most of our fire stopping work happens after the building is up. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind, and they are easy to forget. We close the openings listed on your schedule, using the specified sealant and detail. The enquiries we see most involve head-of-wall gaps with no fire seal and fire seals cut back for extra cables and never reinstated, on linear gaps at wall heads, small duct penetrations where the tested detail allows and cable penetrations. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Chelwood Gate, preparation and product choice get the time they need.
Rural conversions around Chelwood Gate can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

What we can’t put right
Honesty saves time and money. New sealant won’t cure:
- Construction that lacks the fire resistance the seal relies on
- Issuing fire ratings or certificates for seals
- Designing or specifying fire stopping, which sits with the designer or fire engineer
Not sure which it is? You can phone 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.
Surfaces we seal
- Cable penetrations
- Linear gaps at wall heads
- Pipe penetrations
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
- Service gaps in risers
How the job changes by surface
Drylining partitions
Service holes through plasterboard are frequently oversized or ragged. If the gap exceeds the tested range, sealant alone won’t do, and the detail may call for board patching or another product.
Linear joints
Joints at the top of partitions may need to move as the slab above deflects. We use the product and backing the detail names for that movement, along the full length of the run.
Chelwood Gate: questions and answers
Is Chelwood Gate too small for you to travel to?
No. Small places get the same service as large ones. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
Will you take on work at estates like Horsted Keynes Business Park, close to Chelwood Gate?
Yes. We cover Chelwood Gate and the area around it, including industrial estates, business parks and retail parks such as Horsted Keynes Business Park. A few photos and the unit address let us price the work.
How soon can the area be used again?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
What site paperwork can you supply?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Can weather delay the job?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
What happens if it’s left?
The longer openings stay, the more there tend to be: every new cable or pipe adds another. Keeping on top of it after each round of works keeps the job small and avoids a much larger catch-up later. Converted and older buildings near places like Chelwood Gate tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
Pricing service penetrations depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

Keeping the joints sound
Regular inspection catches problems early. In particular:
- Flag new cables with no seal around them
- Look above ceilings when tiles are lifted for other jobs
- Put resealing into every M&E and fit-out package
- Keep general-purpose fillers away from compartment walls
After every round of M&E works, check that the openings created have been sealed. A short check at the end of each job saves a long hunt later.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. Then the seal goes in while the area is open instead of being left for someone else.
