Fire stopping in Brockley, done properly
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4, with results classified under BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. We work on linear gaps at wall heads, joints between fire-resisting walls and floors and service gaps in risers, and what we are called in for most is hidden openings found during inspections and expanding foam used as fire stopping. A single leaking joint is often how a building in Brockley first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Fit-outs and M&E works in London buildings often leave service penetrations open behind ceilings and in risers. Fire-rated sealant goes in where it’s the specified item; where a collar, wrap or batt is called for instead, we flag it.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant.

Brockley: questions and answers
Can you cope with the access rules in a London building?
Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method. The ULEZ covers the whole of Greater London, which we allow for
Can you work in a care home near Brockley with residents in?
Yes. We work around residents’ routines, a room or two at a time. Tell us about any infection-control or safeguarding requirements and we’ll work to them.
Are you members of a third-party fire-stopping installer scheme?
No. We don’t hold a third-party fire-stopping installer certificate. Our credentials are CHAS accreditation, Constructionline membership and CSCS-carded applicators, and we are fully insured. Where a client or main contractor requires a scheme member, we will say so straight away rather than waste your time.
Do the same rules apply to fire stopping in Scotland?
Scotland sets its own building regulations, with Technical Handbooks. Wherever the site is, our work follows the specification and the tested detail.
Which standards are fire seals tested to?
BS EN 1366-3 covers penetration seals and BS EN 1366-4 covers linear joints. Classification follows BS EN 13501-2. The rating applies to the product as tested.
What site paperwork can you supply?
Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.
Can one quote cover more than one building?
Yes. A group of buildings can go on one quote, with one point of contact.
Signs you need fire stopping in Brockley
Head-of-wall joints and wall-to-wall junctions are frequent weak points. Deflection and building movement can open these gaps. Linear joint details set a width range and movement capability, and the seal has to sit within them.
Look out for the following:
- Unsealed openings around new pipes and cables
- Damaged fire seals in risers and voids
- Unsealed joints where partitions meet the slab
- Fire-stopping items raised at inspection or handover
Shop fits in centres such as Lewisham Shopping Centre, 1.2 miles north-east of Brockley, can bring new services through fire-resisting walls between units, which then need the specified seal.

Compartment walls and floors in Brockley
In England, Approved Document B covers fire stopping of openings and penetrations. 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. In London buildings, frequent fit-outs and M&E changes are a common reason fire stopping gets breached. Where fire-rated sealant is specified, we install it to the tested detail under the building’s permit-to-work arrangements.
Workshops and IT rooms at colleges like Christ the King: Aquinas Sixth Form College, 1 mile to the north of Brockley, are re-serviced often, leaving penetrations to seal. Wherever services are added at a hospital such as University Hospital Lewisham, 0.7 miles to the east of Brockley, the compartment line has to be made good with the specified product.
Brockley is about 1 mile south of New Cross, in Greater London. Any commercial site in Brockley is covered, whether it’s a single job or part of a planned programme. We work across 764 places in Greater London, from busy centres to rural villages.

We cover commercial and managed buildings on Ivy Road, Nash Road and Lindal Road and the roads nearby. If your building is just outside Brockley, we cover Crofton Park (1 mile south-east), Honor Oak (1 mile west), Ladywell (1 mile east), Forest Hill (1 mile south-west) and Nunhead (1 mile north-west). Nearby towns on our patch include London (4 miles north-west), City of Westminster (7 miles north-west), Marylebone (7 miles north-west), Kensington (8 miles north-west), St Pancras (6 miles north-west) and Shoreditch (5 miles north).

How the quote is worked out
The price varies from site to site. Expect it to depend on:
- The total length or number of joints
- How accessible the joints are
- Working within restricted access windows
- Travel to remote or island sites
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.
Before you send an enquiry
Whether it’s one area or a whole building, the same details help:
- When you need the work done
- What the building is and how it’s used
- Whether an asbestos survey exists
- Specification clauses that apply
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, phone 01277 525 020 or use the quote form.
How a job runs
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes a single visit for a short list of penetrations, or a phased programme for a whole building, and our waste is bagged and taken away as we go. In Brockley, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Unsuitable fillers and loose debris are taken out of each opening.
- Mineral wool or other backing goes in wherever the detail asks.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- If an opening needs something other than sealant, we tell you instead of improvising.
Getting the site ready
- Share your working hours and any access restrictions
- Point out parking and an unloading spot
- Flag any permit to work we will need
Getting a fixed quote
Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

Aftercare for building managers
Keep the joints in good shape with a few simple steps:
- Check with the data sheet before painting over fire sealant
- Include service cupboards in routine inspections
- Don’t let anyone top up a fire seal with the wrong product
- Treat an open penetration as a priority repair
Don’t patch a fire-rated seal with anything outside its tested detail. A repair should use the original product, installed the same way, or a new specification from the designer.
On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned, and the work runs in step with the M&E.

What we can’t put right
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Writing the fire-stopping specification
- Walls or floors that aren’t fire-resisting to begin with
- Signing off or certifying a building’s fire stopping
If you are not sure, just give us a call on 01277 525 020 or use the quote form and we will give you a straight answer before you book.
Joints and surfaces we work on
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
- Service gaps in risers
- Pipe penetrations
