About our fire stopping in Farringdon
Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. We use sealant where it is the specified product, and we tell you when a detail calls for something else. We work on cable penetrations, linear gaps at wall heads and service gaps in risers, and the usual reasons a site gets in touch are openings left by services added after handover and snag lists that include open service penetrations. Whoever orders the work in Farringdon, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Rural conversions around Farringdon can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

When to bring in a specialist
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
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:
- Fire doors, dampers or other fire safety equipment
- Issuing fire ratings or certificates for seals
- Writing the fire-stopping specification
If you’re not sure, just ring 01277 525 020 or email the details over and we will give you a straight answer before you book.

What affects the price in Farringdon
We price every job individually. The main factors are:
- The product specified
- Any access equipment needed
- Whether the work must be split into stages
- Whether old sealant has to be cut out first
Pricing service penetrations depends on quantities, condition and access, plus any specification you’re working to. Call for a quote.
What to include in your enquiry
It doesn’t need to be a full survey. These details are enough to start:
- Whether the building will be occupied during the work
- Rough lengths or quantities, or drawings if you have them
- The product your specification calls for
- Any dates the work must fit around
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, speak to us on 01277 525 020 or email drawings and photos.
Your questions answered
Is hospital work, at somewhere like Alton Community Hospital, something you do?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
What happens to BS 476 references for fire stopping in Farringdon?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Is your workmanship covered by a guarantee?
Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.
Does weather matter for sealant work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also speak to us on 01277 525 020 or email us. Photos, drawings or a joint schedule help us quote quickly.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
How long does a job like this take?
That varies with the scale of the job, but the work usually takes a single visit for a short list of penetrations, or a phased programme for a whole building. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
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. For buildings around smaller places like Farringdon, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Penetration seals near Farringdon
At about 47 miles from central London, Farringdon 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, and the gaps need sealing with the specified product. For England, the fire stopping of penetrations is dealt with in Approved Document B. 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. Our part stays the same: the specified product, installed to its tested detail.
For a building such as Church of All Saints, new heating or data runs are the usual reason penetrations need sealing. Wherever services are added at a hospital such as Alton Community Hospital, 2 miles north of Farringdon, the compartment line has to be made good with the specified product.

Signs you need fire stopping in Farringdon
A common fault is a product that was never fire-rated in the first place: expanding foam or a general-purpose sealant pushed into a gap to tidy it. The opening looks sealed but has no fire test evidence behind it and has to be removed.
These are often picked up first by site or facilities staff:
- Seals that don’t match their tested detail
- Unsealed penetrations discovered above suspended ceilings
- Unsealed openings around new pipes and cables
- Old intumescent sealant that has split away
Where a unit on an estate such as Farringdon Industrial Centre, which lies west of Farringdon, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.
What to look for in a quote
- What the guarantee covers, and for how long
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Health and safety accreditation such as CHAS
- How the joint faces will be prepared and primed
How a job runs
Before we leave any area, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. If others near Farringdon need work, visits can be combined. A fixed quote is given before anything starts.
- We read the specification, drawings or penetration schedule you send.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Unsuitable fillers and loose debris are taken out of each opening.
- We fit the backing the detail asks for, to the stated depth.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- If an opening needs something other than sealant, we tell you instead of improvising.
Getting the site ready
- Arrange parking or a loading space
- Clear stock, furniture or equipment away from the joints
- Send any specification or drawings in advance
