Fire stopping in Aldwych
Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We hold no third-party fire-stopping installer certificate. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. We work on pipe penetrations, small duct penetrations where the tested detail allows and service gaps in risers, and the failures we’re asked to look at most are open linear gaps along the top of fire-resisting walls and old intumescent sealant that has split away. Whether you call it commercial sealant work, mastic application or joint sealing, in Aldwych it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
After a fit-out or new cabling in a London building, risers and ceiling voids are where open service gaps tend to be found. If sealant is the specified product we fit it to its tested detail, and if the detail needs something else, you will hear it from us.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Do you need fire stopping in Aldwych?
Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Deflection and building movement can open these gaps, and a product not tested for that movement may crack. The tested detail for a linear joint states the width and movement it covers.
Site and facilities staff are often the first to spot these:
- Fire seals cut back for extra cables and never reinstated
- Unsealed joints where partitions meet the slab
- Fire stopping installed outside its tested range
- Fire sealant pulled out of the opening
On a hospital site such as Royal London Hospital for Integrated Medicine, which lies north of Aldwych, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.

From enquiry to sign-off
We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- We ask for the product and detail your designer has specified.
- We sort the openings by the detail each one needs.
- Improvised fillers and failed sealant are removed.
- Where the detail needs backing, it goes in at the stated depth.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- Completed areas are checked with you, with the records agreed when we quoted.
What we need from you
- Let us know about inductions and permits
- Warn occupants and staff about the work
- Share your working hours and any access restrictions

Advice
Different surfaces, different methods
Plastic pipes
Waste and drainage pipes through floors are a frequent case. The detail decides whether sealant alone is enough, and we’ll never swap a specified collar for sealant.
Drylining partitions
Drylined fire walls are tested in a particular build-up. We check that the product’s detail covers that partition type and board thickness before sealing.

Service penetrations in Aldwych buildings
Every new tenant in a London building tends to bring new cabling, and with it new holes through compartment walls. Penetrations are sealed with the specified product, to its tested detail, under the building’s own permit rules. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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.
At a university such as King's College London, which lies east of Aldwych, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work. Colleges such as Kensington College of Business, less than half a mile north-west of Aldwych, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.
Aldwych is about 1 mile north-west of London, in Greater London. Aldwych sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. Aldwych is one of 764 places in Greater London on our list.
If you need fire stopping in W1D, WC2H and W1F, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed. If your site is on Shoe Lane, Drury Lane and New Square or close by, we can quote for service penetrations. Main routes into Aldwych include the A4 and A301. If your building is just outside Aldwych, we cover Clare Market (1 mile north), Covent Garden (1 mile west), Temple Bar (1 mile east), Temple (1 mile east) and Adelphi (1 mile south-west). A short drive away, we cover Kensington (4 miles west), Walthamstow (6 miles north-east), Hampstead (4 miles north-west), Ruislip (13 miles west), Stockwell (3 miles south) and Orpington (13 miles south-east).

Should maintenance staff do it?
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
What sets the cost
These are the things that shape the price:
- Site requirements such as inductions and permits
- Any access equipment needed
- Working within restricted access windows
- Whether old sealant has to be cut out first
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.
What we need to price the job
For an accurate fixed quote, we need a clear picture of the site. Send us:
- Photos of the joints, close up and from further back
- Your programme or deadline
- The type of building and who uses it
- Any specification or named product
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, call 01277 525 020 or send details through our quote form.
FAQs: Aldwych
Do you work in London buildings with loading restrictions?
Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method. All of Greater London is inside the ULEZ, and our planning allows for it
How does the move away from BS 476 affect penetration seals in Aldwych?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Are you CHAS accredited and on Constructionline?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
How long will the new sealant last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
Can the building stay open while you work?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
How much does the work cost?
Each job is quoted on its own details. To get one, speak to us on 01277 525 020 or email drawings and photos with a description of the work.
