How fire stopping works in Southampton

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 will confirm with the quote. The enquiries we see most involve expanding foam used as fire stopping and snag lists that include open service penetrations, on cable penetrations, service gaps in risers and small duct penetrations where the tested detail allows.

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish.

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.
We gun the sealant in to the specified depth around each service and tool it.
We walk the completed areas with you and confirm the records agreed at quote stage.

Fire stopping across Southampton: the area picture

Hospitals, schools, care homes, offices and blocks across Southampton all rely on fire-resisting walls and floors. Where fire-rated sealant is the specified product for a service penetration or linear gap, we install it to the manufacturer’s tested detail.

London and the South East are among the drier parts of the UK, but external sealing in Southampton still needs a dry joint and the right temperature, and damp or frosty mornings can hold it up. In the parts of Southampton near the sea, the elevations facing the weather are where sealant gives up first, so they’re worth inspecting more often.

Southampton: Residences at universities like University of Southampton (to the north-west of Southampton) have compartment walls that must be resealed whenever services change. On a site such as Bitterne Business Centre, 0.7 miles to the east of Southampton, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product.

What happens if it’s left?

An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. While the openings can be reached, sealing them is normally straightforward. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption.

Work for main contractors and building owners

We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.

As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.

After the work

Cleaning and maintenance staff play a part too. Share these points with them:

Look above ceilings when tiles are lifted for other jobs
Ask which product is in place before decorating
Report damaged or disturbed seals as soon as they’re spotted
Have penetrations checked while they can still be seen

During planned inspections, look at seals in risers, cupboards and voids. Look for cracks, unsealed new cables and gaps that have been enlarged and get them dealt with.

A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate, and it helps at inspections.

Surface by surface

Plastic pipes

Plastic pipes soften and collapse in a fire. Small sizes are sometimes covered by an intumescent sealant detail. We confirm material and size first and tell you if sealant isn’t the right product.

Metal pipes

Copper and steel pipes are a common service penetration for fire-rated sealant. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on, so we check each one.

Honest limits

Honesty saves time and money. Fresh joints won’t solve:

Designing or specifying fire stopping, which sits with the designer or fire engineer
Construction that lacks the fire resistance the seal relies on
Approving the work on behalf of building control

Common questions from Southampton clients

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Can you work to our specification?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

Does weather matter for sealant work?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Can you seal any opening with fire-rated sealant?

No. Sealant is the right product only where the tested detail says so. Collars, wraps, batts and boards exist for openings sealant doesn’t cover, and we’ll tell you when that applies.

Is Southampton in your area?

Yes. We take on work across Southampton, and the same phone number covers every area.

Which sealant will you use?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Will you just go over the old sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
