Fire stopping for Furnace Green sites
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
From enquiry to sign-off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For a site in Furnace Green, we plan so the whole job is done in one go where possible. Clear photos and measurements help us bring the right products.
- First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Unsuitable fillers and loose debris are taken out of each opening.
- Mineral wool or other backing goes in wherever the detail asks.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- If an opening needs something other than sealant, we tell you instead of improvising.
Getting the site ready
- Send asbestos survey details if the building is pre-2000
- Tell us which areas need to stay in use
- Tell staff and tenants when we will be in
Getting a fixed quote
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.

About our fire stopping in Furnace Green
Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We hold no third-party fire-stopping installer certificate, and we won’t pretend otherwise. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. We work on cable penetrations, linear gaps at wall heads and joints between fire-resisting walls and floors, and what we’re called in for most is fire-rated sealant that has cracked or shrunk back and expanding foam used as fire stopping. Whether you call it commercial sealant work, mastic application or joint sealing, in Furnace Green it comes down to the same thing: the right product in a properly prepared joint.
Buildings in a smaller place such as Furnace Green that need fire-rated sealing are typically schools, care homes, surgeries, small offices and flats over shops. Around those penetrations, fire-rated sealant is installed if specified, with depth, backing and gap all as tested.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Looking after the joints
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Agree the fire-stopping specification before services go in
- Have penetrations checked while they can still be seen
- Report damaged or disturbed seals as soon as they’re spotted
- Keep general-purpose fillers away from compartment walls
Never top up a fire seal with foam, ordinary silicone or filler. Repairs need the same product and detail as the original unless the designer specifies otherwise.
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.
Cost factors for service penetrations
There’s no standard rate for sealant work, because every site is different. What we look at:
- Any access equipment needed
- The product specified
- Working within restricted access windows
- Travel to remote or island sites
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.
What we need to price the job
To price the job accurately, we need a clear picture of the site. Useful things to include:
- Whether an asbestos survey exists
- Any dates the work must fit around
- Access details, including height
- Drawings or a marked-up plan, if available
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.
Fire stopping in Furnace Green: the local picture
For England, the fire stopping of penetrations is dealt with in Approved Document B. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail. Furnace Green sits in or beside Crawley, a twentieth-century planned town. Offices and public buildings from that era have usually had several generations of new services, and every change can breach a fire-resisting wall.
At a healthcare site like Crawley Hospital, which lies north-west of Furnace Green, new services through compartment walls are a constant, and each needs the specified seal. For a hotel such as Europa Gatwick Hotel, which lies north-east of Furnace Green, penetration seals are worth checking after any refit or services upgrade.
Furnace Green is about 2 miles south-east of Crawley, in West Sussex. We send applicators to Furnace Green for service penetrations. Across West Sussex, 373 places are covered, Furnace Green among them. We also cover Brighton, around 18 miles from Furnace Green.
Commercial sites across RH10 are covered. For a building on Marion Road, Holder Road and Bolton Road or nearby, we can quote for service penetrations. Close to Furnace Green, our area also takes in Pease Pottage (2 miles south-west), Worth Abbey (2 miles east), Balcombe Lane (2 miles south-east), Balcombe (3 miles south-east) and Staplefield (4 miles south). A short drive away, we cover Horsham (7 miles west), Haywards Heath (7 miles south), Burgess Hill (10 miles south), East Grinstead (7 miles east), Billingshurst (14 miles south-west) and Bewbush (3 miles west).

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Furnace Green can sit alongside others in a wider programme.
What sealant work can’t fix
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Issuing fire ratings or certificates for seals
- Openings that need collars, wraps, batts or boards rather than sealant
- Gaps in walls that were never built as compartment walls
If in doubt, give us a call on 01277 525 020 or email drawings and photos and we will say what we think before you book.
Surfaces we seal
- Pipe penetrations
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
- Cable penetrations
Questions we’re asked in Furnace Green
Does your area include sites such as Maidenbower Business Park, near Furnace Green?
Yes. Our area takes in Furnace Green and its surroundings, with estates and business parks such as Maidenbower Business Park included. Photos and a short description are enough for a first look.
Do you work in occupied care homes around Furnace Green?
Yes. We work around residents’ routines, a room or two at a time. We follow the home’s own procedures throughout.
How do I request a quote?
You can use the quote form on this site; alternatively, call 01277 525 020 or send photos by email. Include photographs or drawings if you have them.
Do you offer coloured sealant?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
How much does the work cost?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and we will price the work to it.
Do you approve fire stopping for building control?
No. Approval sits with the designer, principal designer or building control. We will confirm the products and details used and agree any further records when we quote.
Do you need fire stopping in Furnace Green?
Some seals fail because the wrong product went in: expanding foam or a general-purpose sealant pushed into a gap to tidy it. It may look closed, but it has no tested fire performance in that position and has to be removed.
These are often picked up first by site or facilities staff:
- Hidden openings found during inspections
- Penetration schedules that need working through
- Fire-rated sealant that has cracked or shrunk back
- Seals that don’t match their tested detail
Offices at parks like Maidenbower Business Park (0.9 miles north-east of Furnace Green) are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail.
Questions to ask before you book
