About our fire stopping in Norwood Hill
Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Other openings need collars, wraps, batts, pillows or boards. If the detail calls for something other than sealant, we say so rather than force sealant into it. We work on joints between fire-resisting walls and floors, small duct penetrations where the tested detail allows and cable penetrations, and the failures we’re asked to look at most are unsealed joints where partitions meet the slab and non-fire-rated filler around services. For commercial sealant work in Norwood Hill, you deal with one contact from quote to sign-off, whether it’s one building or several.
Barn and farm-building conversions near places like Norwood Hill often combine new partitions with old walls. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
A 12-month guarantee applies to all our work. Should something we installed fail, call 01277 525 020 or email us and we will come back to it.

What happens if it’s left?
A seal that doesn’t match its tested detail gives false comfort. The fix is to remove it and reinstall to the detail. One visit to deal with every failing joint makes more sense than several trips to a place like Norwood Hill, rather than one at a time. Photos of every joint help us quote for the whole job.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

Questions we’re asked in Norwood Hill
Can you take on a job at a hospital such as Farmfield Hospital (psychiatric)?
Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
How does the move away from BS 476 affect penetration seals in Norwood Hill?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Will your applicators have CSCS cards?
Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
Do you need to see the site first?
That depends on the size and complexity of the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
How do we ask for a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.
Building owners, agents and FMs in Norwood Hill
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.
Fire stopping in Norwood Hill: the local picture
In England, Approved Document B covers fire stopping of openings and penetrations. 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. What we install is set by the specification, and it goes in to the tested detail. Norwood Hill is about 23 miles from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.
For a hotel such as Stanhill Court Hotel, which lies south-west of Norwood Hill, penetration seals are worth checking after any refit or services upgrade. For a building at a site such as Gatwick Business Park, which lies south-east of Norwood Hill, a check of penetration seals after each fit-out is good practice.

Diagnose, treat, sign off
When we get to site, 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 any cutting starts, and the work typically takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. Rural sites near Norwood Hill may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- We ask for the product and detail your designer has specified.
- 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.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Getting the site ready
- Tell us what induction or permit system the site runs
- Warn occupants and staff about the work
- Agree which areas must stay open

Common problems we fix in Norwood Hill
Mixing products or improvising a detail breaks the link with the test evidence. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are the usual culprits.
If one of these sounds familiar, it’s time for a closer look:
- Hidden openings found during inspections
- Fire stopping installed outside its tested range
- Unsealed joints where partitions meet the slab
- Old intumescent sealant that has split away
For a hospital such as Farmfield Hospital (psychiatric), which lies south-east of Norwood Hill, penetration sealing is usually phased ward by ward, with infection-control rules agreed first.
Before you book anyone
- Their public liability cover
- How they’ll work around occupants
- Is the sealant right for the movement and the substrate?
- How the joint faces will be prepared and primed
Aftercare for building managers
Regular inspection catches problems early. In particular:
- Don’t let anyone top up a fire seal with the wrong product
- File the specified details where the next contractor can find them
- Treat an open penetration as a priority repair
- Include service cupboards in routine inspections
New services after handover are a common way fire stopping gets breached. Building it into each contractor’s sign-off keeps the walls intact.
Specify fire stopping early on refits, not as an afterthought. Details can then be picked to suit the actual pipes, cables and ducts, and the work runs in step with the M&E.
When it isn’t the sealant
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Approving the work on behalf of building control
- Reviewing a building’s overall fire safety
- Designing or specifying fire stopping, which sits with the designer or fire engineer
If in doubt, speak to us on 01277 525 020 or email the details over and we’ll say what we think.
