Fire stopping for commercial buildings in Henham
We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We don’t hold a third-party fire-stopping installer certificate and we’d rather say that up front. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. We work on small duct penetrations where the tested detail allows, pipe penetrations and cable penetrations, and the usual reasons a site gets in touch are unsealed joints where partitions meet the slab and service penetrations left open after M&E works. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Henham is the same: the right product in a properly prepared joint.
Barn and farm-building conversions near places like Henham often combine new partitions with old walls. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Where services cross fire walls in Henham
At about 33 miles from central London, Henham is within reach of the capital. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls; the gaps need the specified seal. Fire stopping of openings and penetrations in England falls under Approved Document B. 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. Our part stays the same: the specified product, installed to its tested detail.
Colleges such as Arthur Findlay College, 2.9 miles south-west of Henham, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product. In a building such as Church of St Mary the Virgin, any service penetration through a fire-resisting wall should be sealed to the specified detail.
Henham is about 6 miles north-east of Bishop's Stortford, in Essex. If you’re looking for fire stopping in Henham, we can help, as we do across Essex. 644 places across Essex fall within our area, including Henham. Our London page has more on work in that area (33 miles or so).

Should maintenance staff do it?
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
When something else is needed
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Approving the work on behalf of building control
- Plastic pipes whose detail calls for a collar or wrap
- Fire risk assessments, a job for a competent assessor
If you’re not sure, just ring 01277 525 020 or email drawings and photos and we will give you a straight answer.
Joints and surfaces we work on
- Service gaps in risers
- Cable penetrations
- Small duct penetrations where the tested detail allows
- Linear gaps at wall heads
- Pipe penetrations
- Joints between fire-resisting walls and floors

Common questions from Henham clients
What does the BS 476 change mean for fire-rated sealant in Henham?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Can you work on a hospital site such as Herts and Essex Hospital?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
What do you charge?
We don’t publish prices, because every site is different. Send photos or drawings and we’ll price it at a fixed figure.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
Is the work guaranteed?
Yes. It runs for twelve months and covers how we prepared and sealed the joints, though not damage or work by other trades.
Can weather delay the job?
Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
How long does a job like this take?
The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.
Why act early in Henham
Open penetrations multiply: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable and avoids a much larger catch-up later. Halls, stores and units around places like Henham may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

When to call us in Henham
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.
Look out for the following:
- Openings found when ceilings come down for a refit
- Open linear gaps along the top of fire-resisting walls
- Fire stopping installed outside its tested range
- Fire sealant pulled out of the opening
Offices at parks like Golds Nursery Business Park, 1.2 miles to the south-west of Henham, are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail.

Cost factors for service penetrations
Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:
- Which sealant the job calls for
- Site requirements such as inductions and permits
- Whether the work must be split into stages
- How accessible the joints are
The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.
Sending details for a quote
To price the job accurately, we need a clear picture of the site. Send us:
- Any specification or named product
- Access details, including height
- Approximate linear metres or a joint schedule
- The postcode of the building
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.
