Fire stopping for businesses in Farthing Street
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
From enquiry to sign-off
On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work normally takes a single visit for a short list of penetrations, or a phased programme for a whole building. 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 start with your penetration schedule, drawings or specification.
- We plan the sequence of floors, risers and voids with you.
- We compare every service penetration with its tested detail before sealing.
- Unsuitable material is removed and the opening cleaned so the seal starts clean.
- 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
- Share the asbestos register for older buildings
- Send your site hours and access windows
- Tell us what induction or permit system the site runs

How we handle fire stopping in Farthing Street
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4 and the results are classified to 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. Site teams most often ask us about fire sealant pulled out of the opening and expanding foam used as fire stopping, across small duct penetrations where the tested detail allows, service gaps in risers and linear gaps at wall heads. Facilities teams, main contractors and managing agents in Farthing Street tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
In London, higher-risk residential buildings under the Building Safety Act bring extra scrutiny of fire-stopping records. We install what the designer or fire engineer has specified, and if you need records of the work, tell us and we will confirm with the quote.
Work we carry out in Greater London comes with a 12-month guarantee. If an installation problem shows up, give us a call on 01277 525 020 or use the quote form and we will arrange a return visit.

Building owners, agents and FMs in Farthing Street
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
CHAS accredited and a Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
What the job involves on each surface
Plastic pipes
Waste and drainage pipes through floors are a frequent case. The detail decides whether sealant alone is enough.
Metal pipes
Heat travels along metal pipework, and the tested detail may ask for insulation beyond the wall. We follow whatever the detail requires and flag anything we can’t match.
Fire-rated sealing for Farthing Street buildings
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. Farthing Street has two care or nursing homes no more than 2 miles away. Where new services have gone through compartment walls in a care setting, the gaps need the specified product.
For a building such as St Mary's Church, new heating or data runs are the usual reason penetrations need sealing. Tenant changes at parks like Glebe Farm Business Park, 0.8 miles to the west of Farthing Street, bring new data and services, and openings through fire-resisting walls need the specified seal. At a college such as Shaftesbury Nash College, 2.7 miles to the north-west of Farthing Street, checking penetration seals after summer M&E works is good practice.

Farthing Street: questions and answers
Can you work in a London building with booked loading and goods-lift slots?
Yes. Inductions, permits and timed loading are routine for us in London. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly.
Will you work in a care home in Farthing Street without moving residents out?
Yes. We work around residents’ routines, a room or two at a time. We follow the home’s own procedures throughout.
Is the work guaranteed?
Yes. Workmanship is guaranteed for 12 months on every job.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
How do you choose the sealant?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Is any job too small?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.

What else we do in Farthing Street
What sets the cost
A fixed quote reflects the actual work. It takes account of:
- How much there is to seal
- The size and state of each joint
- Any access equipment needed
- Specialist products, such as fire-rated or hygienic sealants
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.
Before you send an enquiry
Good information means a firmer quote. When you get in touch, include:
- Rough lengths or quantities, or drawings if you have them
- The postcode of the building
- Whether the building will be occupied during the work
- The asbestos register, for older buildings
Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. The easiest way is to give us a call on 01277 525 020 or email us.
When something else is needed
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is any of the following:
- Signing off or certifying a building’s fire stopping
- Fire doors, dampers or other fire safety equipment
- Large openings beyond what any sealant detail covers
If you are not sure, just ring 01277 525 020 or send photos by email and we’ll give you a straight answer.
Surfaces we seal
- Pipe penetrations
- Small duct penetrations where the tested detail allows
- Linear gaps at wall heads
- Service gaps in risers
- Cable penetrations
- Joints between fire-resisting walls and floors
Site staff or a sealant specialist?
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
