Fire stopping in Marden Ash
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4, with results classified under BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. So our job is to reproduce that arrangement faithfully. The enquiries we see most involve improvised or mixed-product fire seals and openings left by services added after handover, on pipe penetrations, joints between fire-resisting walls and floors and cable penetrations. Searching for sealant specialists in Marden Ash? We have been sealing commercial buildings since 2005.
Smaller places such as Marden Ash still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Quoting for work in Marden Ash
A fixed quote reflects the actual work. It allows for:
- How much existing material needs removing
- Specialist products, such as fire-rated or hygienic sealants
- Site requirements such as inductions and permits
- Distance, for remote addresses
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.
Details that help us quote
To price the job accurately, we need to understand the site. Send us:
- Asbestos survey details if the building is older
- Photos of the joints, close up and from further back
- The site address and postcode
- Any dates the work must fit around
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to speak to us on 01277 525 020 or use the quote form with what you know.
Your questions answered
Is hospital work, at somewhere like St. Margaret's Hospital, something you do?
Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.
Is Hallsford Bridge Industrial Estate, near Marden Ash, within your area?
Yes. Our area takes in Marden Ash and its surroundings, with estates and business parks such as Hallsford Bridge Industrial Estate included. A few photographs and the unit address let us price the work.
What do you charge?
Every job gets its own fixed quote. To get one, call 01277 525 020 or email drawings and photos.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
What if there’s asbestos in the old mastic?
Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
On site: what to expect
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then handed back before we move to the next. If others near Marden Ash need work, visits can be combined. You’ll have a fixed quote before work starts.
- We read the specification, drawings or penetration schedule you send.
- On site, each opening is checked against the tested detail it is meant to follow.
- Unsuitable fillers and loose debris are taken out of each opening.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.
Preparing the site
- Send asbestos survey details if the building is pre-2000
- Share your working hours and any access restrictions
- Let us know about inductions and permits
Ask for a quote
Every quote starts with the facts: 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.

Leave it or put it right?
An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. While the openings can be reached, sealing them is normally straightforward. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. Around Marden Ash, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

What else we do in Marden Ash
After the work
Problems stay small when the joints are checked regularly. Specifically:
- Put resealing into every M&E and fit-out package
- Have penetrations checked while they can still be seen
- Report damaged or disturbed seals as soon as they’re spotted
- Record which product was used where
New services after handover are a common way fire stopping gets breached. A short check at the end of each job saves a long hunt later.
On fit-outs, get the fire-stopping specification agreed before the services go in. Details can then be picked to suit the actual pipes, cables and ducts, and installation follows the programme.
Fire stopping in Marden Ash: the local picture
Central London is about 20 miles from Marden Ash. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls. For England, the fire stopping of penetrations is dealt with in Approved Document B. 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. Either way, we install the specified product to its tested detail.
On estates like Hallsford Bridge Industrial Estate, 0.7 miles to the east of Marden Ash, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal. For a school such as Chipping Ongar Primary School, penetration sealing fits best at the end of the summer works. In a building such as St James, any service penetration through a fire-resisting wall should be sealed to the specified detail.

Honest limits
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Issuing fire ratings or certificates for seals
- Large openings beyond what any sealant detail covers
If in doubt, call 01277 525 020 or email us and we’ll say what we think before you book.
What we seal
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Cable penetrations
- Linear gaps at wall heads
- Service gaps in risers
What the job involves on each surface
Metal pipes
Heat travels along metal pipework. If the detail needs something beyond sealant, we tell you.
Drylining partitions
Holes in board are often cut larger than needed. An oversized hole may be outside the sealant’s range and we will tell you what the detail says instead.
