How we handle fire stopping in Ickenham
Facilities managers in Ickenham often find open service penetrations when ceilings come down for other work. If a specification already covers those walls and floors, we can reseal to it, matching the product and detail it names. Where there isn’t one, the designer or fire engineer needs to set one first. We work on pipe penetrations, small duct penetrations where the tested detail allows and joints between fire-resisting walls and floors, and the usual reasons a site gets in touch are fire-stopping items raised at inspection or handover and seals disturbed by maintenance and left open. Looking for mastic applicators who cover Ickenham? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
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.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Different surfaces, different methods
Drylining partitions
Plasterboard partitions are tested as a specific construction. The sealant detail has to be tested in that wall type, with the stated board layers.
Plastic pipes
Plastic pipes soften and collapse in a fire. Small sizes are sometimes covered by an intumescent sealant detail. We check the pipe material and diameter against the detail before we start.
FAQs: Ickenham
What does the BS 476 change mean for fire-rated sealant in Ickenham?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Do you seal service penetrations in hotels around Ickenham?
Yes, where fire-rated sealant is the specified product. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we’ll tell you if the detail calls for a collar, wrap or batt instead.
Is the work guaranteed?
Yes. The 12-month guarantee covers our preparation and application, though not damage or work by other trades.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Are your applicators CSCS-carded?
Yes. Our applicators hold CSCS cards.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
Will you quote for a small job?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
What happens if it’s left?
A seal that doesn’t match its tested detail gives false comfort. Correcting it means cutting it out and starting again with the specified product, and doing it once, properly, is cheaper. Failed sealant in a building in Ickenham can quickly affect neighbours, tenants or the floor below. Dealing with it early is simpler for everyone.
What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a fixed quote once you have the details.

Aftercare for building managers
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Foam or ordinary sealant is never a fire-seal repair
- Have penetrations checked while they can still be seen
- Check risers and ceiling voids after each round of works
- File the specified details where the next contractor can find them
Don’t patch a fire-rated seal with anything outside its tested detail. A repair should use the original product, installed the same way.
Keep a register of where seals are and what they are made of. It tells the next contractor exactly what to reinstate.
From enquiry to sign-off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Planning a London job such as one in Ickenham starts with access. Give us the hours we can be on site and we’ll schedule to suit.
- We read the specification, drawings or penetration schedule you send.
- On site, each opening is checked against the tested detail it is meant to follow.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Getting the site ready
- Tell staff and tenants when we’ll be in
- Arrange parking or a loading space
- Tell us your opening times and when work is allowed

Advice
When to call us in Ickenham
Mixing products or improvising a detail breaks the link with the test evidence. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are the usual culprits.
Any of the following is a good reason to get the joints checked over:
- Non-fire-rated filler around services
- Damaged fire seals in risers and voids
- Snag lists that include open service penetrations
- Fire-rated sealant that has cracked or shrunk back
In a retail centre such as Brook Retail Park (2.5 miles east of Ickenham), any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail.
Questions to ask before you book
- Health and safety accreditation such as CHAS
- Whether old or failed sealant will be cut out, not overlaid
- Will CSCS-carded applicators be on site?
- The named product and why it was chosen
Site staff or a sealant specialist?
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Penetration seals near Ickenham
Fire stopping of openings and penetrations in England falls under Approved Document B. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail. Every new tenant in a London building tends to bring new cabling, and with it new holes through compartment walls. We install fire-rated sealant where it is specified and work within the building manager’s permit system.
On a hospital site such as Hillingdon Hospital (2.3 miles south of Ickenham), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits. For a building at a site such as Uxbridge Business Park, 1.4 miles to the west of Ickenham, a check of penetration seals after each fit-out is good practice.
Ickenham is about 1 mile north of Hillingdon, in Greater London.
