Fire stopping for Gun Hill sites

How we handle fire stopping in Gun Hill
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. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance on buildings around Gun Hill. If you have expanding foam used as fire stopping and fire seals cut back for extra cables and never reinstated, we can help, on service gaps in risers, small duct penetrations where the tested detail allows and pipe penetrations alike. Facilities teams, main contractors and managing agents in Gun Hill tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
A job near Gun Hill is normally planned around one visit, with the specification and photographs sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Gun Hill: questions and answers
Is Gun Hill too far out for you?
No. Small places get the same service as large ones. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Can you take on a job at a hospital such as Amberstone Hospital?
Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.
What site paperwork can you supply?
Each site asks for different documents, so tell us what you need and we will confirm it when we quote.
Do you have third-party installer accreditation for fire stopping?
No. We don’t hold a third-party fire-stopping installer certificate. We are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded. Where a client or main contractor requires a scheme member, we’ll say so right away rather than waste your time.
Is sealant suitable for all service openings?
No. It depends on the tested detail for that wall or floor and service. Collars, wraps, batts and boards exist for openings sealant doesn’t cover, and we flag those rather than improvise.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.
Do you guarantee your work?
Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.
From enquiry to sign-off
We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact. For work around Gun Hill, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- 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.
- We fit the backing the detail asks for, to the stated depth.
- 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.
Preparing the site
- Make sure the joints can be reached
- Send any specification or drawings in advance
- Send your site hours and access windows

Advice
After the work
A few simple habits keep the new joints working:
- Look above ceilings when tiles are lifted for other jobs
- Record which product was used where
- Brief every trade that openings they make must be sealed
- Treat an open penetration as a priority repair
Allow the manufacturer’s stated cure time before boxing in or decorating. Not every fire-rated product can be painted.
Ask every contractor who works in risers or voids to report openings they create. It costs little and catches breaches early.
Work for main contractors and building owners
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
What happens if it’s left?
Inspections and handover checks often pick up fire stopping. Late discoveries can delay handover while openings are reopened and resealed which is why earlier is better. Older rural buildings around Gun Hill move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Why appoint us
- Joints cleaned back to sound surfaces

How the quote is worked out
Before we quote, we look at:
- The size and state of each joint
- The total length or number of joints
- The site’s rules and procedures
- Travel to remote or island sites
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.
Sending details for a quote
A good diagnosis starts with the right details. Tell us:
- Clear photographs of the problem areas
- Anything awkward about access or site hours
- Any specification or named product
- Where the site is, with the postcode
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.
What sealant work can’t fix
We check first that sealant really is the fix. It won’t put right:
- Deciding what a wall or floor needs, which belongs to the designer
- Gaps in walls that were never built as compartment walls
- Large openings beyond what any sealant detail covers
If in doubt, speak to us on 01277 525 020 or email a schedule or drawings and we will say what we think.
Where we work in Gun Hill

Penetration seals near Gun Hill
At about 43 miles from central London, Gun Hill is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls; the gaps need the specified seal. In England, Approved Document B covers fire stopping of openings and penetrations. 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. Either way, we install the specified product to its tested detail.
Theatres, wards and plant rooms at sites like Amberstone Hospital (to the south-east of Gun Hill) all have compartment walls crossed by services. Industrial units on estates such as Hackhurst Lane Industrial Estate, 1.7 miles south of Gun Hill, often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal.
