Fire stopping in South Ealing, done properly
No fire sealant works on its own: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. Before we seal anything, we check the opening against the detail it is meant to follow, and we say so if it doesn’t fit. We work on small duct penetrations where the tested detail allows, pipe penetrations and service gaps in risers, and the failures we are asked to look at most are builders’ foam or ordinary silicone in compartment walls and fire seals cut back for extra cables and never reinstated. Whether you call it commercial sealant work, mastic application or joint sealing, the work in South Ealing is the same: the right product in a properly prepared joint.
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.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Diagnose, treat, sign off
Occupied buildings need a little choreography. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- First we go through the drawings, schedule or specification for the seals.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- We fit the backing the detail asks for, to the stated depth.
- 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.
Preparing the site
- Tell us your opening times and when work is allowed
- Explain the parking and delivery arrangements
- Let us know about inductions and permits

Advice
Signs you need fire stopping in South Ealing
When a seal departs from its tested detail, the evidence no longer covers it. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are the usual culprits.
What tends to prompt an enquiry:
- Openings left by services added after handover
- Damaged fire seals in risers and voids
- Hidden openings found during inspections
- Head-of-wall gaps with no fire seal
Wherever services are added at a hospital such as Clayponds Hospital, 0.5 miles to the south-east of South Ealing, the compartment line has to be made good with the specified product.
Questions to ask before you book
- How joint depth will be controlled
- Whether their applicators hold CSCS cards
- Are they CHAS accredited or on Constructionline?
- What the guarantee covers, and for how long
Common questions from South Ealing clients
Can work at a site such as The University of West London fit around teaching?
Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Will you take on work at estates like Phoenix Trading Estate, close to South Ealing?
Yes. Our area takes in South Ealing and its surroundings, with estates and business parks such as Phoenix Trading Estate included. To start, just give us a call on 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Can you tell us what fire stopping our building needs?
No, we don’t design fire stopping. Once you have a specification, we can price and install the sealant elements of it.
Do you take on small jobs?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
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.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
When is resealing likely to be due?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

What else we do in South Ealing
Fire-rated sealing for South Ealing buildings
In England, Approved Document B covers fire stopping of 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. What we install is set by the specification, and it goes in to the 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.
In a retail centre such as Kew Retail Park, 2 miles south-east of South Ealing, any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail. On estates like Phoenix Trading Estate, 0.6 miles to the south of South Ealing, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.
South Ealing is about 1 mile south of Ealing, in Greater London. Any commercial site in South Ealing is covered, whether it’s a single job or part of a planned programme. Our Greater London coverage takes in 764 places. Our London page has more on work in that area, about 9 miles away.

Different surfaces, different methods
Drylining partitions
Plasterboard partitions are tested as a specific construction. We check that the product’s detail covers that partition type and board thickness before sealing.
Cables and cable bundles
New data and power cables are the most common breach we see. Openings around new cables are resealed to the detail, and we tell you if the bundle exceeds what sealant covers.
Why act early in South Ealing
An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product. In South Ealing, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.
