How we handle fire stopping in Locksbottom
Opened ceilings and riser doors often reveal service openings nobody sealed. If a specification already covers those walls and floors, we can reseal to it using the product and detail it sets out. With no specification in place, the first step sits with your designer or fire engineer, not with us. If you’re dealing with openings found when ceilings come down for a refit and openings left by services added after handover, we can help, on service gaps in risers, linear gaps at wall heads and pipe penetrations alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Locksbottom is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Fit-outs and M&E works in London buildings often leave service penetrations open behind ceilings and in risers. 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.
Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Should maintenance staff do it?
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Certain joints really need a specialist: for instance 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.
Compartments and services around Locksbottom
Locksbottom has a number of hotels close by, all within 2 miles. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. 10 care or nursing homes sit less than 2 miles from Locksbottom. In a care home, any new pipe or cable through a fire-resisting wall should be sealed to the specified detail.
For a building at a site such as Glebe Farm Business Park, which lies south-west of Locksbottom, a check of penetration seals after each fit-out is good practice. On a hospital site such as Princess Royal University Hospital (less than half a mile south of Locksbottom), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.

On site: what to expect
Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before the next one starts. All of Greater London is in the ULEZ, and kerbside space in Locksbottom can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We ask for the product and detail your designer has specified.
- Openings are measured and grouped by detail.
- Improvised fillers and failed sealant are removed.
- 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.
- We walk the completed areas with you and confirm the records agreed at quote stage.
What we need from you
- Point out any areas we must not close
- Confirm the product named in the specification
- Point out parking and an unloading spot

Advice
Signs you need fire stopping in Locksbottom
Plenty of openings were simply never closed, often hidden above suspended ceilings or behind boxing. They come to light during inspections, refits or when another trade lifts a tile.
Most enquiries start with one or more of the following:
- Hidden openings found during inspections
- Head-of-wall gaps with no fire seal
- Fire sealant pulled out of the opening
- Unsealed openings around new pipes and cables
Colleges such as Bromley College (to the north-west of Locksbottom) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.
What to look for in a quote
- Will failed sealant be removed rather than covered?
- Their pre-qualification and accreditations
- Whether primer will be used where the manufacturer specifies it
- How they’ll work around occupants
Different surfaces, different methods
Plastic pipes
Plastic waste pipes through slabs come up often. The detail decides whether sealant alone is enough, and we won’t substitute it for a specified collar.
Masonry and concrete
Many seals are made in blockwork, brickwork or concrete slabs. Dust and loose debris are cleared out of the opening, so the sealant and any backing sit properly.
Why it’s worth doing now in Locksbottom
The longer openings stay, the more there tend to be: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable and avoids a much larger catch-up later. In Locksbottom, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Questions we’re asked in Locksbottom
Can work at a site such as Bromley College fit around teaching?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Do you work in London buildings with loading restrictions?
Yes, we plan every London job around the building’s own access rules. Share the building’s contractor rules and we’ll work to them. All of Greater London is inside the ULEZ, and our planning allows for it
Do you need to see the site first?
Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.
What does an EI 60 rating mean?
The tests are BS EN 1366-3 for penetrations and BS EN 1366-4 for linear joints, and classification is to BS EN 13501-2. An EI 60 seal kept its integrity and insulation for 60 minutes as tested and the installation has to match the test.
Will you sign off the seals for us?
No. Sign-off belongs to the designer or building control, not the installer. We will confirm the product and detail installed, and you can tell us what other records you need at quote stage.
Is the BS 476 change in 2029 relevant to fire stopping?
In England, references to the older BS 476 national classes are being removed from Approved Document B from 2 September 2029, subject to the Government’s transitional arrangements. After that, the European classification under BS EN 13501-2 is the route. Product selection stays with your designer.
Can you send site paperwork?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.
What affects the price in Locksbottom
