Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Signs you need fire stopping in Erith
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, so it has to come out.
Things that usually lead to an enquiry:
- Openings left by services added after handover
- Penetration schedules that need working through
- Builders’ foam or ordinary silicone in compartment walls
- Seals that don’t match their tested detail
For a unit at a centre such as Broadway Shopping Centre (1.9 miles south-west of Erith), penetration seals are worth checking after each shop fit.

How we handle fire stopping in Erith
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints and the results are classified to BS EN 13501-2. A rating such as EI 60 only holds when the product is installed as it was tested. Reproducing the tested arrangement on site is the part we take care of. We work on cable penetrations, linear gaps at wall heads and service gaps in risers, and what we are called in for most is fire stopping installed outside its tested range and old intumescent sealant that has split away. Facilities teams, main contractors and managing agents in Erith tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
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.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Aftercare for building managers
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Check with the data sheet before painting over fire sealant
- Put resealing into every M&E and fit-out package
- Arrange inspection before areas are covered up
- Ask the designer to confirm details early on refits
After every round of M&E works, check that the openings created have been sealed. Building it into each contractor’s sign-off keeps the walls intact.
Looking at service areas on a regular cycle pays off. A cracked or disturbed seal found early is a small job compared with dozens found at once.
Fire stopping around Erith: points for this area
In England, Approved Document B covers fire stopping of openings and penetrations. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Either way, we install the specified product to its tested detail. London’s office and residential buildings are refitted constantly, and each round of cabling or pipework can leave open penetrations. Penetrations are sealed with the specified product, to its tested detail, under the building’s own permit rules.
Wherever services are added at a hospital such as Erith and District Hospital (less than half a mile south-west of Erith) the compartment line has to be made good with the specified product. At a university such as University of Greenwich Avery Hill Campus, 4.6 miles to the south-west of Erith, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.
Erith is about 3 miles north-west of Dartford, in Greater London. Across the DA8 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed.

Questions about Erith
How does the move away from BS 476 affect penetration seals in Erith?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Can you work around term dates at a campus such as University of Greenwich Avery Hill Campus?
Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Do you guarantee your work?
Yes. It runs for twelve months and covers how we prepared and sealed the joints, though not damage or work by other trades.
Will your applicators have CSCS cards?
Yes. We use CSCS-carded applicators, which many sites require.
Do you take on small jobs?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
Can the sealant be colour-matched?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.
What’s the quickest route to a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.
Should maintenance staff do it?
Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

How the job changes by surface
Cables and cable bundles
Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. Bundle size, cable type and the space between cables all matter.
Linear joints
Head-of-wall gaps, slab edges and wall junctions are linear joints. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers and the installation has to fit inside those limits.
Building owners, agents and FMs in Erith
Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Erith can form part of a wider programme across Greater London.
For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
Diagnose, treat, sign off
At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- We ask for the product and detail your designer has specified.
- We sort the openings by the detail each one needs.
- Old or wrong materials are cut out.
- Where the detail needs backing, it goes in at the stated depth.
- We gun the sealant in to the specified depth around each service and tool it.
- Completed areas are checked with you, with the records agreed when we quoted.
Getting the site ready
