Do you need fire stopping in Cock Clarks?
Most open service penetrations are left by later work. New cabling, rerouted pipework or a data route drilled through a riser leaves an opening that nobody returns to. Over a few years of fit-outs, a wall can collect a lot of these.
What tends to prompt an enquiry:
- Unsealed penetrations discovered above suspended ceilings
- Improvised or mixed-product fire seals
- Unsealed joints where partitions meet the slab
- Builders’ foam or ordinary silicone in compartment walls
At a healthcare site like Baddow Hospital, which lies west of Cock Clarks, new services through compartment walls are a constant, and each needs the specified seal.

Fire stopping for commercial buildings in Cock Clarks
On a fit-out or refurbishment, we follow the services contractors floor by floor. We work from your penetration schedule or marked-up drawings. Tell us what records you need and we’ll confirm with the quote. The enquiries we see most involve service penetrations left open after M&E works and unsealed joints where partitions meet the slab, on small duct penetrations where the tested detail allows, service gaps in risers and pipe penetrations. Facilities teams, main contractors and managing agents in Cock Clarks tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Smaller places such as Cock Clarks still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

When something else is needed
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Openings that need collars, wraps, batts or boards rather than sealant
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Gaps in walls that were never built as compartment walls
If you’re not sure, just call 01277 525 020 or email the details over and we will give you a straight answer before you book.
Surfaces we seal
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Linear gaps at wall heads
- Pipe penetrations
- Cable penetrations
Penetration seals near Cock Clarks
At about 34 miles from central London, Cock Clarks is within reach of the capital. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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. We install whatever has been specified, to the product’s tested detail.
Offices at parks like Wycke Hill Business Park, 2.4 miles north-east of Cock Clarks, are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail.

Maintenance after handover
Keep the joints in good shape with a few simple steps:
- Record which product was used where
- Ask the designer to confirm details early on refits
- Have penetrations checked while they can still be seen
- Check risers and ceiling voids after each round of works
Allow the manufacturer’s stated cure time before boxing in or decorating. Not every fire-rated product can be painted, and the data sheet says which.
Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job.
How a job runs
At the end of each section, we remove the tape, clean down and inspect every joint. Where the sealant needs time to cure before use, we tell you and sign the area. Rural sites near Cock Clarks may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- We ask for the product and detail your designer has specified.
- We sort the openings by the detail each one needs.
- Old or wrong materials are cut out.
- Where the detail needs backing, it goes in at the stated depth.
- We gun the sealant in to the specified depth around each service and tool it.
- Completed areas are checked with you, with the records agreed when we quoted.
Getting the site ready
- Confirm the product named in the specification
- Clear stock, furniture or equipment away from the joints
- Warn occupants and staff about the work
Getting a fixed quote
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

What else we do in Cock Clarks
Cock Clarks: questions and answers
Can you work on a hospital site such as Baddow Hospital?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is a smaller place like Cock Clarks outside your area?
Not at all. Cock Clarks is within our area. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.
How much does the work cost?
Every job gets its own fixed quote. To get one, phone 01277 525 020 or send details through our quote form.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.
Do you design or specify fire stopping?
No, that isn’t our role. With the designer’s details in hand, we can price the sealant elements and point out anything needing another product.
Do you have third-party installer accreditation for fire stopping?
No. We are not members of a third-party fire-stopping installer scheme. 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 straight away rather than waste your time.
How many days will you need on site?
The duration is planned around your programme and the access we’re given. We will give you an estimate of time on site when we quote.
General trades versus a specialist
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Some joints are best left to specialists: 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.
What happens if it’s left?
Sealing behind the M&E trades area by area beats a sweep at the end. While the area is still open, every opening is easy to see and reach, and the right detail can be checked at the time. One visit to deal with every failing joint makes more sense than several trips to a place like Cock Clarks, rather than one at a time. Photos of every joint help us quote for the whole job.
The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote once you have the details.
