Fire stopping for Crews Hill sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Fire stopping in Crews Hill, done properly
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints. A rating such as EI 60 only holds when the product is installed as it was tested. So our job is to reproduce that arrangement faithfully. Site teams most often ask us about non-fire-rated filler around services and hidden openings found during inspections, on linear gaps at wall heads, small duct penetrations where the tested detail allows and pipe penetrations. Searching for sealant specialists in Crews Hill? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
After a fit-out or new cabling in a London building, risers and ceiling voids are where open service gaps tend to be found. If sealant is the specified product we fit it to its tested detail, and if the detail needs something else, you will hear it from us.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

What happens if it’s left?
Inspections and handover checks often pick up fire stopping. Finding unsealed or improvised openings late can hold up a programme. Failed sealant in a building in Crews Hill can quickly affect neighbours, tenants or the floor below. Dealing with it early is simpler for everyone.

How a job runs
On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work typically takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. For a job in Crews Hill, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- First we go through the drawings, schedule or specification for the seals.
- 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.
Preparing the site
- Move anything stored against the joints
- Share your working hours and any access restrictions
- Explain the parking and delivery arrangements

Compartments and services around Crews Hill
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. London’s office and residential buildings are refitted constantly, and each round of cabling or pipework can leave open penetrations. We seal to the specification and the product’s tested detail, working within the building’s permits.
In a building such as Church of St John the Baptist, any service penetration through a fire-resisting wall should be sealed to the specified detail. On a hospital site such as Chase Farm Hospital, which lies south of Crews Hill, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.

When to call us in Crews Hill
When a seal departs from its tested detail, the evidence no longer covers it. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are the usual culprits.
What tends to prompt an enquiry:
- Fire-stopping items raised at inspection or handover
- Fire seals cut back for extra cables and never reinstated
- Fire sealant pulled out of the opening
- Openings left by services added after handover
Workshops and IT rooms at colleges like Capel Manor College, 1.9 miles to the east of Crews Hill, are re-serviced often, leaving penetrations to seal.

Your questions answered
Does your area include sites such as Sopers Road Industrial Estate, near Crews Hill?
Yes. Estates, retail parks and business parks around Crews Hill, Sopers Road Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.
Do you take on work at healthcare sites like Chase Farm Hospital?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
Is fire stopping in Scotland covered by different guidance?
Building standards in Scotland are separate from England’s. Either way, we install the specified sealant to its tested detail.
Can you fire stop behind the services contractors?
Yes. Send the schedule or marked-up drawings and the specified product details and a fixed quote follows. We can follow the services contractor floor by floor so areas aren’t left open.
What if there’s asbestos in the old mastic?
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.
Is Crews Hill in your area?
Yes. We cover Crews Hill, and the simplest way to start is to give us a call on 01277 525 020 or send photos by email.
What do BS EN 1366-3 and BS EN 13501-2 mean?
Penetration seals are tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. Results are classified under BS EN 13501-2, where E is integrity, I is insulation and the number is minutes, as in EI 60. That rating only holds when the product is installed to its tested detail.
Site staff or a sealant specialist?
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Owners, agents and contractors
Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Crews Hill can form part of a wider programme across Greater London.
What we can’t put right
Being straight saves everyone time. New sealant won’t cure:
- Deciding what a wall or floor needs, which belongs to the designer
- Large openings beyond what any sealant detail covers
- Fire risk assessments, a job for a competent assessor
Not sure which it is? You can phone 01277 525 020 or email the details over and we will tell you honestly.
