Fire stopping for commercial buildings in Yiewsley
On a fit-out or refurbishment, we follow the services contractors floor by floor. We work from your penetration schedule or marked-up drawings alongside the manufacturer’s details. Tell us what records you need and we’ll confirm with the quote. We work on small duct penetrations where the tested detail allows, pipe penetrations and joints between fire-resisting walls and floors, and the usual reasons a site gets in touch are non-fire-rated filler around services and unsealed openings around new pipes and cables. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Yiewsley 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. Fire-rated sealant goes in where it’s the specified item; where a collar, wrap or batt is called for instead, we flag it.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, give us a call on 01277 525 020 or email a schedule or drawings and we’ll arrange a return visit.

Do you need fire stopping in Yiewsley?
Some seals fail because the wrong product went in: expanding foam or a general-purpose sealant pushed into a gap to tidy it. It may look closed, but it has no tested fire performance in that position, so it has to come out.
These are often picked up first by site or facilities staff:
- Fire stopping installed outside its tested range
- Unsealed joints where partitions meet the slab
- Builders’ foam or ordinary silicone in compartment walls
- Openings left by services added after handover
Workshops and IT rooms at colleges like Uxbridge College (to the south-west of Yiewsley) are re-serviced often, leaving penetrations to seal.

Small ducts
Some fire-rated sealant details cover small ducts. Larger or fire-rated ductwork usually needs a different solution set by the designer.
Linear joints
Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed, and we work within it.
Fire stopping around Yiewsley: what changes locally
The area within 2 miles of Yiewsley holds several hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. For England, the fire stopping of penetrations is dealt with in 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.
Campus buildings at universities such as Brunel University of London, 3.5 miles west of Yiewsley, see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified. For a building at a site such as Adrienne Business Centre (0.7 miles east of Yiewsley), a check of penetration seals after each fit-out is good practice.

How a job runs
Tell us your site hours and access windows and we will plan around them. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area. All of Greater London is in the ULEZ, and kerbside space in Yiewsley 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 start with your penetration schedule, drawings or specification.
- We plan the sequence of floors, risers and voids with you.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out so the seal starts clean.
- The specified backing and sealant go in to depth and are finished neatly.
- We tell you about openings that need a different product.
What we need from you
- For older buildings, check the asbestos register before work
- Flag any permit to work we will need
- Agree which areas must stay open
Ask for a quote
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

How the quote is worked out
Before we quote, we look at:
- Backing rod, priming and other preparation
- Removal of failed or old sealant
- Specialist products, such as fire-rated or hygienic sealants
- The total length or number of joints
The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote when you are ready.
Details that help us quote
There’s no need for a formal survey. A few details are enough to get going:
- Whether the building will be occupied during the work
- Photos of the joints, close up and from further back
- When you need the work done
- Approximate linear metres or a joint schedule
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
What sealant work can’t fix
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Signing off or certifying a building’s fire stopping
- Construction that lacks the fire resistance the seal relies on
- Writing the fire-stopping specification
If you are not sure, just speak to us on 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.
Surfaces we seal
- Linear gaps at wall heads
- Pipe penetrations
- Cable penetrations
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Joints between fire-resisting walls and floors
Work for main contractors and building owners
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.
FAQs: Yiewsley
Do you work in London buildings with loading restrictions?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Share the building’s contractor rules and we will work to them. The ULEZ covers the whole of Greater London, which we allow for
Would you work within a site like Ealing Hospital?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
How do I request a quote?
The quote form is the simplest route, though you can also phone 01277 525 020 or send photos by email. Photos, drawings or a joint schedule help us quote quickly.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Who decides which product is used?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Do you hold third-party fire-stopping installer certification?
No, and we won’t imply otherwise. Some clients require third-party installer schemes even though the law doesn’t, so check your contract first. Where it isn’t required, we install the specified sealant to the maker’s details.
