Leave it or put it right?
An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. Putting it right is usually a modest job when the openings are accessible. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. Converted and older buildings near places like Langstone tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
Pricing service penetrations depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

Fire stopping for commercial buildings in Langstone
A fire-rated sealant is only one part of a tested system: 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, linear gaps at wall heads and cable penetrations, and the usual reasons a site gets in touch are non-fire-rated filler around services and hidden openings found during inspections. A specialist sealant contractor works differently from a general builder: in Langstone, that means joint design, primers and backing rod as standard.
Rural conversions around Langstone can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

On site: what to expect
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, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Rural sites near Langstone may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- First we confirm the product and tested details named in the specification.
- Openings are measured and grouped by detail.
- Old or wrong materials are cut out.
- 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.
Getting the site ready
- Send any specification or drawings in advance
- Share the asbestos register for older buildings
- Let us know about inductions and permits

Your questions answered
How does the move away from BS 476 affect penetration seals in Langstone?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Do you work on fire-rated sealing in hotels in Langstone?
Yes. We install fire-rated and intumescent sealant where it is specified. Work is done room by room so the hotel keeps trading; design and sign-off stay with the designer and building control.
Can staff carry on working while you are here?
In the majority of cases, yes. Phased work can be planned so areas stay in use.
Do you work in Langstone?
Yes. We take on work across Langstone.
Do you offer coloured sealant?
It depends on the product. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.
Will you come and look before quoting?
That depends on the size and complexity of the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.
How long does a typical visit take?
That varies with the scale of the job, but the work usually takes anything from one day to a planned run of visits, depending on the number of seals and the access. For bigger or phased jobs, we’ll set out a timescale with the quote.
What we are called out for in Langstone
A common fault is a product that was never fire-rated in the first place: expanding foam or a general-purpose sealant pushed into a gap to tidy it. The opening looks sealed but has no fire test evidence behind it, so it has to come out.
Clients typically get in touch after noticing something like this:
- Fire-rated sealant that has cracked or shrunk back
- Unsealed penetrations discovered above suspended ceilings
- Expanding foam used as fire stopping
- Penetration schedules that need working through
Campus buildings at universities such as University of Portsmouth - Langstone Campus (to the south-west of Langstone) see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified.

Doing it in-house
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
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.
Where services cross fire walls in Langstone
Langstone is about 60 miles from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls; the gaps need the specified seal. For England, the fire stopping of penetrations is dealt with in Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.
For a building such as Saint Nicholas' Chapel, new heating or data runs are the usual reason penetrations need sealing. At a healthcare site like Elmleigh Hospital, 1.4 miles north of Langstone, new services through compartment walls are a constant, and each needs the specified seal.

Surface by surface
Cables and cable bundles
Single cables and small bundles are often within a fire-rated sealant’s tested detail. Bundle size, cable type and the space between cables all matter and we work within those limits.
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.
