Fire stopping around Nob's Crook: what changes locally
For England, the fire stopping of penetrations is dealt with in Approved Document B. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. We install whatever has been specified, to the product’s tested detail. Nob's Crook lies roughly 63 miles out from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls, and the gaps need sealing with the specified product.

Colleges such as Eastleigh College - Desborough Campus (2.6 miles south-west of Nob's Crook) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.

Fire stopping in Nob's Crook
Facilities managers in Nob's Crook often find open service penetrations when ceilings come down for other work. Where the walls and floors already have a fire-stopping specification, we can work to it. With no specification in place, the first step sits with your designer or fire engineer, not with us. If you’re dealing with head-of-wall gaps with no fire seal and fire seals cut back for extra cables and never reinstated, we can put it right, whatever the surface. Most enquiries from Nob's Crook start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
Rural conversions around Nob's Crook 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.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

FAQs: Nob's Crook
Do you take on work at healthcare sites like Wessex Hospital?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Is Nob's Crook too far out for you?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
How many days will you need on site?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
Do you seal openings left by new services?
Yes, provided a specification covers them. Openings left by new services are among the most common jobs we see and we close them with the specified product.
What’s the quickest route to a quote?
You can use the quote form on this site; alternatively, give us a call on 01277 525 020 or email the details over. Include photographs or drawings if you have them.
Do you need to see the site first?
It depends on the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.
Is your workmanship covered by a guarantee?
Yes. Our workmanship is backed for 12 months on every job.
Why deal with it now?
A seal that doesn’t match its tested detail gives false comfort. Correcting it means cutting it out and starting again with the specified product, so it makes sense to get it right first time. One visit to deal with every failing joint makes more sense than several trips to a place like Nob's Crook, rather than one at a time. Send photographs of each area and we will quote for the lot.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

Signs you need fire stopping in Nob's Crook
Openings in fire-resisting walls usually appear when services are added or changed. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser leaves an opening that nobody returns to. Across several fit-outs, the openings add up.
Things that usually lead to an enquiry:
- Hidden openings found during inspections
- Seals that don’t match their tested detail
- Fire seals cut back for extra cables and never reinstated
- Penetration schedules that need working through
Hotels like Marwell Hotel, 1.1 miles east of Nob's Crook, are refurbished in phases, and each phase can open up compartment walls.
