Fire stopping in Greater London: how it works

For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. We work from your penetration schedule or marked-up drawings. Tell us what records you need and we will confirm with the quote. Most enquiries involve snag lists that include open service penetrations and old intumescent sealant that has split away, on pipe penetrations, service gaps in risers and linear gaps at wall heads.

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish.

First we confirm the product and tested details named in the specification.
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.
We walk the completed areas with you and confirm the records agreed at quote stage.

Around London

In London, that means premises near St Mary-at-Hill, St George the Martyr and The BFI Reuben Library. You will also find Trinity Arms Public House (less than half a mile south-east), Ark Globe Academy (under half a mile south), Charles Dickens Primary School (less than half a mile north-west) and Newington Gardens (less than half a mile south). London has its own railway station: Elephant & Castle station. A little further out are Surrey Dispensary (less than half a mile south-east) and Baynard's Castle (0.9 miles north). For a walk, there’s Bellenden Road Nature Garden and St. James's Park Lake.

Nearby schools include London School of Musical Theatre (less than half a mile west)

Service penetrations in Greater London buildings

Fit-outs and M&E works in places such as London, City of Westminster and Marylebone are a common reason fire stopping gets breached. We work to the specification and the manufacturer’s installation guidance, and say if the detail calls for something other than sealant.

Around the motorway corridors of the South East, business parks and industrial estates are common, and we cover Greater London along with the rest of the region.

London: For a site team at a college like Morley College London, which lies west of London, fire-rated sealing is best scheduled after the summer works. For a hospital such as Guy's Hospital (under half a mile north-east of London), penetration sealing is typically phased ward by ward, with infection-control rules agreed first.

When something else is needed

Before quoting, we check that sealant is the right answer. It won’t put right:

Designing or specifying fire stopping, which sits with the designer or fire engineer
Large openings beyond what any sealant detail covers
Reviewing a building’s overall fire safety

For managing agents and facilities managers

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Greater London can sit alongside others in a wider programme.

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

Looking after the joints

Your facilities or cleaning team can help the joints last. Pass these on to them:

Check with the data sheet before painting over fire sealant
Settle who seals which penetrations at the start of a project
Foam or ordinary sealant is never a fire-seal repair
Get seals inspected before ceilings and boxing close

Keep the product data and installation details with the building’s fire safety information. It makes later repairs much easier to match.

Make reporting new openings part of every permit to work in service areas. Small habits like this stop openings building up.

When to bring in a specialist

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. For that reason, many FMs and contractors use a sealant specialist from the outset.

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.

Why act early?

Inspections and handover checks often pick up fire stopping. Late discoveries can delay handover while openings are reopened and resealed.

Questions to ask before you book

Whether their applicators hold CSCS cards
Is the sealant right for the movement and the substrate?
Their plan for phasing and protecting the area
Their approach to joint depth and backing

Common questions from Greater London clients

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.

How do I request a quote?

You can use the quote form on this site; alternatively, phone 01277 525 020 or email us. Include photographs or drawings if you have them.

What about RAMS and site documents?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

How much does the work cost?

There isn’t a price list, as every site differs. With photos or drawings, we can give you a fixed quote.

Are you fully insured?

Yes. Our insurance certificate can be sent alongside the quote.

What happens if old sealant might contain asbestos?

The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
