Fire stopping across Broomhill

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Your questions answered

Is Broomhill too far out for you?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Do you take on work at healthcare sites like St Martins Hospital?

Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

How long before the joints can be used?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.

Can weather delay the job?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

What’s the quickest route to a quote?

The quote form is the simplest route, though you can also phone 01277 525 020 or send details through our quote form. Include photos or drawings if you have them.

Do the same rules apply to fire stopping in Scotland?

Our area runs from Greater London and the South East to every part of Scotland. In Scotland, clause 2.1.14 of the non-domestic Technical Handbook says service penetrations should keep at least the fire resistance of the wall or floor, with proprietary products tested for the end use.

How long does a typical visit take?

It depends on the scope, though a typical visit usually takes anything from one day to a planned run of visits, depending on the number of seals and the access. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

How we handle fire stopping in Broomhill

Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We hold no third-party fire-stopping installer certificate. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. We work on cable penetrations, linear gaps at wall heads and pipe penetrations, and the failures we are asked to look at most are snag lists that include open service penetrations and head-of-wall gaps with no fire seal. A specialist sealant contractor works differently from a general builder: in Broomhill, that means joint design, primers and backing rod as standard.

Around smaller places like Broomhill, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

How a job runs

Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before the next one starts. Smaller jobs around Broomhill can be grouped with others nearby. A fixed quote is given before anything starts.

  1. We ask for the product and detail your designer has specified.
  2. Openings are measured and grouped by detail.
  3. Improvised fillers and failed sealant are removed.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Preparing the site

  • Make sure the joints can be reached
  • For older buildings, check the asbestos register before work
  • Let building users know which areas are affected

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

When to bring in a specialist

Some joints are best left to specialists: 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 works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Looking after the joints

Regular inspection catches problems early. Specifically:

  • Check risers and ceiling voids after each round of works
  • Report damaged or disturbed seals as soon as they’re spotted
  • Check with the data sheet before painting over fire sealant
  • Make fire stopping part of every scope that crosses a fire-resisting wall

Don’t patch a fire-rated seal with anything outside its tested detail. A repair should use the original product, installed the same way.

A simple record of seal locations and products helps. When a new service goes through, everyone knows which product and detail to match, which saves guesswork.

Work for main contractors and building owners

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Broomhill. Several sites can go on one quote, which keeps the paperwork simple.

When it isn’t the sealant

We check first that sealant really is the fix. It won’t put right:

  • Deciding what a wall or floor needs, which belongs to the designer
  • Issuing fire ratings or certificates for seals
  • Walls or floors that aren’t fire-resisting to begin with

If you’re not sure, just give us a call on 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.

Where we work in Broomhill

  • Service gaps in risers
  • Linear gaps at wall heads
  • Pipe penetrations
  • Small duct penetrations where the tested detail allows
  • Joints between fire-resisting walls and floors
  • Cable penetrations

Surface by surface

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.

Risers and ceiling voids

Voids hide a lot of unsealed openings. We work through the areas on your schedule methodically.

Fire stopping around Broomhill: what changes locally

At about 59 miles from central London, Broomhill is within reach of the capital. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls, and the gaps need sealing with the specified product. In England, Approved Document B covers fire stopping of openings and penetrations. 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. Either way, we install the specified product to its tested detail.

Halls and meeting rooms at places like St Mary's Church sometimes gain new services, and any compartment wall crossed needs the specified seal. On estates like Wingham Industrial Estate (0.8 miles south of Broomhill), the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal. For a hospital such as St Martins Hospital (4.8 miles west of Broomhill), penetration sealing is normally phased ward by ward, with infection-control rules agreed first.

Broomhill is about 6 miles east of Canterbury, in Kent. Businesses, contractors and managing agents in Broomhill use us for work on service penetrations, as part of our coverage of Kent. Broomhill is one of 931 places we cover in Kent for service penetrations. London is covered too, some 59 miles away.

If your building is just outside Broomhill, we cover Wingham (1 mile south), Shatterling (1 mile east), Well Head (1 mile south), Perry (1 mile north-east) and Wingham Green (1 mile south-west). A short drive away, we cover Canterbury (6 miles west), Margate (10 miles north-east), Dover (10 miles south), Folkestone (14 miles south), Ramsgate (9 miles north-east) and Broadstairs (11 miles north-east).
