Fire stopping in Hornchurch
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 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, cable penetrations and pipe penetrations, and the usual reasons a site gets in touch are expanding foam used as fire stopping and fire seals cut back for extra cables and never reinstated. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Hornchurch, preparation and product choice get the time they need.
Taller residential buildings in London may fall under the Building Safety Act’s higher-risk regime, where fire-stopping records get close attention. Our part is installing the specified fire-rated sealant; tell us what records you need and we will confirm with the quote.
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 are clear about what is covered before work starts.

Surface by surface
Masonry and concrete
Openings through concrete vary from tidy cores to rough break-outs. Each gap is measured where it is widest against the detail’s limits, and any that don’t are flagged.
Small ducts
Ducts are only sealed with sealant where the detail allows it. The ductwork, its supports and any dampers are for the ductwork contractor.
Questions about Hornchurch
Would you work within a site like Queens Hospital?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Can you cope with the access rules in a London building?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly.
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 and point out anything needing another product.
How long will the new sealant last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Which standards are fire seals tested to?
BS EN 1366-3 covers penetration seals and BS EN 1366-4 covers linear joints. Results are classified under BS EN 13501-2. The rating applies to the product as tested.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Honest limits
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Walls or floors that aren’t fire-resisting to begin with
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Issuing fire ratings or certificates for seals
Not sure which it is? You can call the office on 01277 525 020 or email drawings and photos and we will tell you honestly before you book.
Surfaces we seal
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Service gaps in risers
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
- Cable penetrations
Our process
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes a single visit for a short list of penetrations, or a phased programme for a whole building, and we clear our waste as we work. In Hornchurch, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- We start with your penetration schedule, drawings or specification.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out first.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
Getting the site ready
- Tell us which areas need to stay in use
- Send asbestos survey details if the building is pre-2000
- Let us know about inductions and permits
Getting a fixed quote
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, give us a call on 01277 525 020 or send photos by email.
Advice
Why it’s worth doing now in Hornchurch
Sealing behind the M&E trades area by area beats a sweep at the end. While the area is still open, every opening is easy to see and reach and each detail can be checked as we go. Failed sealant in a building in Hornchurch can quickly affect neighbours, tenants or the floor below. Putting it right early is less disruptive than dealing with the consequences.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
Why appoint us
- Health and safety: CHAS accredited

Compartments and services around Hornchurch
Hornchurch has a number of hotels close by, all within 2 miles. In hotels, bedroom and corridor walls are typically fire-resisting, so services added in a refit need sealing with the specified product. 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.
Workshops and IT rooms at colleges like New City College, 0.8 miles to the east of Hornchurch, are re-serviced often, leaving penetrations to seal. Shop fits on retail sites such as Rom Valley Retail Park, 1.5 miles to the north-west of Hornchurch, can bring new services through fire-resisting walls between units, to be sealed with the specified product.

Signs you need fire stopping in Hornchurch
Head-of-wall joints and wall-to-wall junctions are frequent weak points. Deflection and building movement can open these gaps. The tested detail for a linear joint states the width and movement it covers.
Site and facilities staff are often the first to spot these:
- Non-fire-rated filler around services
- Old intumescent sealant that has split away
- Penetration schedules that need working through
- Openings found when ceilings come down for a refit
For a hospital such as Queens Hospital, 1.6 miles north-west of Hornchurch, penetration sealing is typically phased ward by ward, with infection-control rules agreed first.

What else we do in Hornchurch
Should maintenance staff do it?
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
