Your questions answered
Could you schedule work at a campus like University of the Arts London for the vacation?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is hospital work, at somewhere like Great Ormond Street Hospital for Children, something you do?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
Do you have public liability insurance?
Yes. We are fully insured, and the certificate can go with your quote.
What about RAMS and site documents?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
What’s the quickest route to a quote?
You can use the quote form on this site; alternatively, give us a call on 01277 525 020 or send details through our quote form. Include photos or drawings if you have them.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Fire stopping for commercial buildings in Holborn
It helps to set out our role at the start. Deciding the specification sits with the designer, the fire engineer and building control; sign-off sits with them too. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance on sites in Holborn. We work on service gaps in risers, pipe penetrations and joints between fire-resisting walls and floors, and the usual reasons a site gets in touch are unsealed openings around new pipes and cables and head-of-wall gaps with no fire seal. Most enquiries from Holborn start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
London has many occupied offices, blocks and mixed-use buildings where services are added and rerouted all the time. Where the specification names fire-rated sealant, it goes in exactly as the manufacturer’s test evidence shows for that wall or floor.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Leave it or put it right?
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 and each detail can be checked as we go. Getting scaffold, permits or access booked in Holborn takes effort, so it makes sense to deal with every failing joint while access is in place.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Fire stopping around Holborn: how the place shapes the job
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. Holborn has plenty of hotels close by, all within 2 miles. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail.
Shop fits in centres such as Brunswick Centre, 0.5 miles north-west of Holborn, can bring new services through fire-resisting walls between units, which then need the specified seal. Colleges such as Central Saint Martins College of Art & Design (to the west of Holborn) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.
Holborn is about 2 miles north-west of London, in Greater London. Any commercial site in Holborn is covered. Holborn is one of 764 places we cover in Greater London.
Postcode districts covered here: WC1X, WC1N and EC1R. For a building on Shoe Lane, Drury Lane and New Square or nearby, send details and we will quote for service penetrations. Access to Holborn is via the A4 and A40 among other routes, so getting applicators and materials to site is simple. Nearby places we also cover include Farringdon (1 mile east), St Pancras (1 mile north-west), Clare Market (1 mile south), Smithfield (1 mile east) and Temple Bar (1 mile south) for service penetrations. Bigger towns within reach include Kensington (4 miles west), Walthamstow (6 miles north-east), Hampstead (4 miles north-west), Ruislip (13 miles west), Brompton (3 miles south-west) and Stockwell (4 miles south).
What’s near Holborn
We work on buildings around The Yorkshire Grey pub, British Library of Political and Economic Science and City Academy. Nearby too are Elizabeth Garrett Anderson School (0.9 miles north) and Lincoln's Inn Fields (less than half a mile south-west). There’s a railway station in Holborn itself: Farringdon station. A little further out are Montfichet's Tower (0.7 miles south-east) and Brunswick Centre (0.5 miles north-west). For a walk, there’s Barnsbury Wood and Ludgate Hill.
Honest limits
Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:
- Walls or floors that aren’t fire-resisting to begin with
- Large openings beyond what any sealant detail covers
- Issuing fire ratings or certificates for seals
If in doubt, ring 01277 525 020 or use the quote form and we’ll say what we think before you book.
Surfaces we seal
- Pipe penetrations
- Joints between fire-resisting walls and floors
- Cable penetrations

- Linear gaps at wall heads
- Service gaps in risers

What else we do in Holborn
Quoting for work in Holborn
Quotes vary with the job. It mainly depends on:
- Travel to remote or island sites
- Removal of failed or old sealant
- Phasing around occupants
- Specialist products, such as fire-rated or hygienic sealants
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Before you send an enquiry
A good diagnosis starts with the right details. Let us know:
- Any specification or named product
- The type of building and who uses it
- Your programme or deadline
- Anything awkward about access or site hours
Need a figure for a tender or a budget? Send the scope and any drawings, and we’ll return a fixed quote you can plan around. If you have questions first, give us a call on 01277 525 020 or email a schedule or drawings.
When to call us in Holborn
When a seal departs from its tested detail, the evidence no longer covers it. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are the usual culprits.
These are often picked up first by site or facilities staff:
- Unsealed penetrations discovered above suspended ceilings
- Fire seals cut back for extra cables and never reinstated
- Fire stopping installed outside its tested range
- Fire-stopping items raised at inspection or handover
Industrial units on estates such as Grand Vitesse Industrial Estate, 1.2 miles to the south-east of Holborn, often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal.
Questions to ask before you book
- The named product and why it was chosen
- The terms of the workmanship guarantee
- Whether primer will be used where the manufacturer specifies it
- Are they CHAS accredited or on Constructionline?
Maintenance after handover
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Leave fire sealant to cure fully before covering it
- Check risers and ceiling voids after each round of works
- Get seals inspected before ceilings and boxing close
- Brief every trade that openings they make must be sealed
After the work, brief anyone else working in the area that the openings are now sealed. If a seal has to be opened for a new service, it should be reinstated to the same detail, by someone who knows the system.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. Then the seal goes in while the area is open instead of being left for someone else.
Diagnose, treat, sign off
Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Most London premises stay occupied while we are on site, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- 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.
Preparing the site
- Confirm the product named in the specification
- Point out any areas we must not close
- For older buildings, check the asbestos register before work
Quotes
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.
