Fire stopping for Upper Farringdon sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Diagnose, treat, sign off
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 before the next one starts. If others near Upper Farringdon need work, visits can be combined, which keeps travel down. You will have a fixed quote before work 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 first.
- Backing and fire-rated sealant are installed to the detail and tooled.
- We tell you about openings that need a different product.
Before we start on site
- Let us know about inductions and permits
- Agree which areas must stay open
- For older buildings, check the asbestos register before work

About our fire stopping in Upper Farringdon
Facilities managers in Upper Farringdon often find open service penetrations when ceilings come down for other work. If a specification already covers those walls and floors, we can reseal to it, matching the product and detail it names. With no specification in place, the first step sits with your designer or fire engineer, not with us. If you have improvised or mixed-product fire seals and openings found when ceilings come down for a refit, we can help. A specialist sealant contractor works differently from a general builder: on jobs in Upper Farringdon, preparation and product choice get the time they need.
For a smaller site near Upper Farringdon, we plan to do all the penetrations in one go, so send the specification and photographs first. Design and sign-off belong to the designer or building control; we install what’s specified.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

What the job involves on each surface
Cables and cable bundles
Single cables and small bundles are often within a fire-rated sealant’s tested detail. The detail limits bundle size and the gaps between and around cables, so we check before sealing.
Linear joints
Joints at the top of partitions may need to move as the slab above deflects. We use the product and backing the detail names for that movement, with no gaps along the run.
What we’re called out for in Upper Farringdon
Some seals fail because the wrong product went in: builders’ foam or ordinary silicone used to fill a hole. 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:
- Openings found when ceilings come down for a refit
- Snag lists that include open service penetrations
- Old intumescent sealant that has split away
- Builders’ foam or ordinary silicone in compartment walls
On a hospital site such as Alton Community Hospital, 2 miles north of Upper Farringdon, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.

Your questions answered
What happens to BS 476 references for fire stopping in Upper 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 Upper Farringdon too small for you to travel to?
No. Small places get the same service as large ones. 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.
Can weather delay the job?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Which sealant will you use?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
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.
Can the building stay open while you work?
In the majority of cases, yes. We phase the work so most of the building stays in use, with each area protected and signed.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Where services cross fire walls in Upper Farringdon
Central London is about 47 miles from Upper Farringdon. Office refits around the commuter belt bring new cabling through fire-resisting walls, and the gaps need sealing with the specified product. Fire stopping of openings and penetrations in England falls under 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. Our part stays the same: the specified product, installed to its tested detail.
For a unit at a site such as Farringdon Industrial Centre (0.7 miles west of Upper Farringdon), new power or data runs between office and warehouse can breach a compartment wall. In a building such as Church of All Saints, any service penetration through a fire-resisting wall should be sealed to the specified detail.

Why act early in Upper Farringdon
It is cheaper to seal service penetrations as each services package finishes than to come back for them later. While the area is still open, every opening is easy to see and reach. Halls, stores and units around places like Upper Farringdon may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.

Maintenance after handover
Cleaning and maintenance staff play a part too. Pass these on to them:
- Have penetrations checked while they can still be seen
- Record which product was used where
- Include service cupboards in routine inspections
- Keep general-purpose fillers away from compartment walls
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.
Keep a register of where seals are and what they are made of. It tells the next contractor exactly what to reinstate, and it helps at inspections.
