Surface by surface
Cables and cable bundles
Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. Bundle size, cable type and the space between cables all matter and we work within those limits.
Risers and ceiling voids
Risers and ceiling voids hold most of a building’s service penetrations. Access is often tight, so we agree it with you in advance, including keys, permits and any isolations.
About our fire stopping in Brock Hill
For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. We work from your penetration schedule or marked-up drawings. Tell us what records you need and we will confirm with the quote. Site teams most often ask us about fire-stopping items raised at inspection or handover and expanding foam used as fire stopping, across small duct penetrations where the tested detail allows, service gaps in risers and joints between fire-resisting walls and floors. Facilities teams, main contractors and managing agents in Brock Hill tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Barn and farm-building conversions near places like Brock 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.
Our workmanship is guaranteed for 12 months, in Brock Hill as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Brock Hill: questions and answers
How does the move away from BS 476 affect penetration seals in Brock Hill?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Is Brock Hill too far out for you?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
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.
Is colour matching possible?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.
Are you CHAS accredited?
Yes. We are CHAS accredited and a Constructionline member.
Can weather delay the job?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Maintenance after handover
To get the most from the new sealant:
- Have penetrations checked while they can still be seen
- Leave fire sealant to cure fully before covering it
- File the specified details where the next contractor can find them
- Look above ceilings when tiles are lifted for other jobs
After the work, brief anyone else working in the area that the openings are now sealed. Any seal cut back for a new service needs reinstating to its tested detail, by someone who knows the system.
Write fire stopping into the scope of any work crossing a compartment wall or floor. Then the seal goes in while the area is open.
Work for main contractors and building owners
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Brock Hill can form part of a wider programme across Essex.
From enquiry to sign-off
On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work normally takes a single visit for a short list of penetrations, or a phased programme for a whole building. If others near Brock Hill need work, visits can be combined. A fixed quote is given before anything starts.
- We start with your penetration schedule, drawings or specification.
- Access, permits and the order of areas are agreed with the site team.
- Each opening is checked for wall or floor type, service, gap and depth.
- Unsuitable material is removed and the opening cleaned so the seal starts clean.
- The specified backing and sealant go in to depth and are finished neatly.
- We tell you about openings that need a different product.
Getting the site ready
- Flag any permit to work we’ll need
- Explain the parking and delivery arrangements
- Agree which areas must stay open

Where services cross fire walls in Brock Hill
Fire stopping of openings and penetrations in England falls under Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. At about 28 miles from central London, Brock Hill is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls, and the gaps need sealing with the specified product.
In a building such as Church of St Margaret, any service penetration through a fire-resisting wall should be sealed to the specified detail. At a healthcare site like Mayflower Community Hospital, which lies west of Brock Hill, new services through compartment walls are a constant, and each needs the specified seal. Schools such as Beauchamps High School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.
Brock Hill is about 2 miles north of Wickford, in Essex. Our applicators travel to Brock Hill for work on service penetrations. Brock Hill is one of 644 places in Essex on our list for service penetrations. For work in that direction, see our London page.

Leave it or put it right?
The longer openings stay, the more there tend to be: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable, rather than turning into a full building survey and reseal. Converted and older buildings near places like Brock Hill tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Gaps in walls that were never built as compartment walls
