Fire stopping for Chainhurst sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
From enquiry to sign-off
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. If others near Chainhurst need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.
- First we confirm the product and tested details named in the specification.
- We sort the openings by the detail each one needs.
- Improvised fillers and failed sealant are removed.
- Mineral wool or other backing is fitted where required.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- Completed areas are checked with you, with the records agreed when we quoted.
Preparing the site
- Point out parking and an unloading spot
- Tell staff and tenants when we will be in
- Point out any areas we must not close
Getting a fixed quote
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Fire stopping in Chainhurst, done properly
We should be clear about what we do and don’t do. The designer, fire engineer or building control decides which fire stopping is required; sign-off sits with them too. What we bring is careful installation of the specified sealant, to the maker’s guidance on buildings around Chainhurst. We work on linear gaps at wall heads, pipe penetrations and small duct penetrations where the tested detail allows, and what we are called in for most is head-of-wall gaps with no fire seal and service penetrations left open after M&E works. One point of contact handles commercial sealant work in Chainhurst from the first photographs to the final walk-round, for single jobs and planned programmes alike.
For a smaller site near Chainhurst, we plan to do all the penetrations in one go, with the specification and photos sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

What we can’t put right
Before quoting, we check that sealant is the right answer. It won’t put right:
- Fire risk assessments, a job for a competent assessor
- Plastic pipes whose detail calls for a collar or wrap
- Gaps in walls that were never built as compartment walls
If in doubt, phone 01277 525 020 or email the details over and we will say what we think before you book.
What we seal
- Cable penetrations
- Service gaps in risers
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Small duct penetrations where the tested detail allows
Different surfaces, different methods
Linear joints
Head-of-wall joints often have to absorb slab deflection. We use the product and backing the detail names for that movement, with no gaps along the run.
Plastic pipes
Waste and drainage pipes through floors are a frequent case. The detail decides whether sealant alone is enough.
Questions we are asked in Chainhurst
What does the BS 476 change mean for fire-rated sealant in Chainhurst?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Does your area include sites such as Woodfalls Industrial Estate, near Chainhurst?
Yes, sites like Woodfalls Industrial Estate are within our area, along with the rest of Chainhurst. To start, just call the office on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day.
How do you choose the sealant?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Can you fit around our working hours?
We are in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
How do I request a quote?
The quote form is the simplest route, though you can also phone 01277 525 020 or email drawings and photos. Photos, drawings or a joint schedule help us quote quickly.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
Looking after the joints
Keep the joints in good shape with a few simple steps:
- Ask which product is in place before decorating
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Get seals inspected before ceilings and boxing close
- Flag new cables with no seal around them
Never top up a fire seal with foam, ordinary silicone or filler. Repairs need the same product and detail as the original.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. That way the opening is sealed while the trade and access are still there.
Compartment walls and floors in Chainhurst
At about 32 miles from central London, Chainhurst is within reach of the capital. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls, and the gaps need sealing with the specified product. Fire stopping of openings and penetrations in England falls under Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail.
For an estates team at a campus like University for the Creative Arts - Maidstone, which lies north of Chainhurst, summer M&E works are usually followed by a round of penetration sealing. At a healthcare site like Oakwood Hospital, 4.6 miles to the north of Chainhurst, new services through compartment walls are a constant, and each needs the specified seal.

- Fire stopping installed outside its tested range
- Hidden openings found during inspections
Where a unit on an estate such as Woodfalls Industrial Estate (2.7 miles west of Chainhurst), has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.
Questions to ask before you book
- Who will actually carry out the work
- How the joint faces will be prepared and primed
- Their pre-qualification and accreditations
- Can the work be phased to keep areas open?
Should maintenance staff do it?
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
