How fire stopping works in Hertfordshire

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. We match each opening to that detail before any sealant goes in, and we say so if it doesn’t fit. We work on small duct penetrations where the tested detail allows, cable penetrations and pipe penetrations, and what we are called in for most is damaged fire seals in risers and voids and fire-stopping items raised at inspection or handover.

Inspect, seal, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off.

We start with your penetration schedule, drawings or specification.
We plan the sequence of floors, risers and voids with you.
Each opening is checked for wall or floor type, service, gap and depth.
Unsuitable material is removed and the opening cleaned.
Backing and fire-rated sealant are installed to the detail and tooled.
Anything outside the detail is reported to you rather than sealed.

How we quote

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Around Watford

In Watford, that means premises near The Estcourt Arms, Watford St John's Church of England Primary School and Church of St Andrew, among other places. Also close by are Cassiobury Park (0.8 miles west) and The Watford UTC (0.5 miles east). Watford has its own railway station: Watford Junction station. Nearby you’ll also find Hilfield Castle (2.8 miles east) and Charter Place (0.5 miles south). The countryside around Watford includes Harrow Weald Common.

Fire-resisting walls and floors across Hertfordshire

Fit-outs and M&E works in places such as Watford, Hemel Hempstead and Stevenage are a common reason fire stopping gets breached. Checking after services work is good practice; tell us what the specification says and we will install to it.

All of Greater London is inside the ULEZ, and much of the South East is within easy reach of the capital, and every job in Hertfordshire starts with access, parking and site rules.

Watford: Office fit-outs on sites such as Colonial Business Park (less than half a mile north-east of Watford) add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it. Tenant changes at centres like Harlequin Centre, 0.6 miles to the south of Watford, often mean new services through walls between units.

Keeping the joints sound

Keep the joints in good shape with a few simple steps:

Look above ceilings when tiles are lifted for other jobs
Flag new cables with no seal around them
Have penetrations checked while they can still be seen
Brief every trade that openings they make must be sealed

Once the seals are in, tell other trades they exist and must not be disturbed. Any seal cut back for a new service needs reinstating to its tested detail.

Specify fire stopping early on refits, not as an afterthought. Details can then be picked to suit the actual pipes, cables and ducts, and installation follows the programme.

Why act early?

It is cheaper to seal service penetrations as each services package finishes than to come back for them later. Openings are visible, access is open and nothing has to be taken down, and the right detail can be checked at the time.

Why it fails

On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is how unsuitable products and improvised details end up in compartment walls and later need putting right.

These are often picked up first by site or facilities staff:

Penetration schedules that need working through
Builders’ foam or ordinary silicone in compartment walls
Open linear gaps along the top of fire-resisting walls
Service penetrations left open after M&E works

Doing it in-house

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

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.

When something else is needed

Being straight saves everyone time. New sealant won’t cure:

Plastic pipes whose detail calls for a collar or wrap
Reviewing a building’s overall fire safety
Issuing fire ratings or certificates for seals

Hertfordshire: questions and answers

Do you have public liability insurance?

Yes. Our insurance certificate can be sent alongside the quote.

Who decides which product is used?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

What’s the quickest route to a quote?

The quote form is the simplest route, though you can also call 01277 525 020 or email the details over. Include photographs or drawings if you have them.

Do you need to see the site first?

It depends on the job. Simple work can often be priced from photos, and bigger or more complex jobs normally get a visit.

Can you seal any opening with fire-rated sealant?

No. It depends on the tested detail for that wall or floor and service. Large openings, many plastic pipes and some ducts need collars, wraps, batts or boards, and we’ll tell you when that applies.

How long does a typical visit take?

The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.
