Fire stopping for commercial buildings in Broadbridge Heath

Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4, with results classified under BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. If you have old intumescent sealant that has split away and unsealed penetrations discovered above suspended ceilings, we can help, on small duct penetrations where the tested detail allows, joints between fire-resisting walls and floors and linear gaps at wall heads alike. A specialist sealant contractor works differently from a general builder: on jobs in Broadbridge Heath, preparation and product choice get the time they need.

Around smaller places like Broadbridge Heath, many commercial buildings are conversions or extensions of older ones, so the wall or floor a service passes through isn’t always what the drawings assume. The right product depends on the wall or floor and the services passing through, and we’ll tell you if the detail calls for something other than sealant.

The 12-month guarantee is for workmanship rather than 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.

FAQs: Broadbridge Heath

Would you work within a site like Horsham Hospital?

Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Could you schedule work at a campus like The College of Richard Collyer for the vacation?

Yes, holiday working periods are the norm on campus jobs. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Is colour matching possible?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

Do you approve fire stopping for building control?

No. We don’t certify or sign off fire stopping, and we hold no third-party fire-stopping installer certificate. We work to the specification and the manufacturer’s installation guidance.

Can you reseal penetrations after our M&E works?

Yes, where there is a specification for those walls and floors. Openings left by new services are among the most common jobs we see.

What will the job cost?

That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we will price it properly.

How long does a typical visit take?

We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.

Signs you need fire stopping in Broadbridge Heath

Openings in fire-resisting walls normally appear when services are added or changed. New cabling, rerouted pipework or a data route drilled through a riser leaves an opening that nobody returns to. Across several fit-outs, the openings add up.

Typical triggers for a call:

  • Fire-rated sealant that has cracked or shrunk back
  • Improvised or mixed-product fire seals
  • Fire-stopping items raised at inspection or handover
  • Builders’ foam or ordinary silicone in compartment walls

Schools such as Shelley Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.

Before you book anyone

  • Will failed sealant be removed rather than covered?
  • Can the work be phased to keep areas open?
  • What site paperwork they can supply
  • How the joint faces will be prepared and primed

Choosing a commercial sealant contractor

Keeping the joints sound

For the best life from the joints:

  • Keep product data and details in the fire safety file
  • Settle who seals which penetrations at the start of a project
  • Check with the data sheet before painting over fire sealant
  • Don’t let anyone top up a fire seal with the wrong product

After the work, brief anyone else working in the area that the openings are now sealed. Any seal cut back for a new service needs reinstating to its tested detail, by someone who knows the system.

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

What the job involves on each surface

Small ducts

Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Bigger ducts and fire-resisting ductwork are normally handled with other products.

Risers and ceiling voids

Openings above suspended ceilings are easy to miss. We follow your schedule area by area.

What affects the price in Broadbridge Heath

Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:

  • Phasing around occupants
  • Quantities, in metres or numbers
  • Travel to remote or island sites
  • Removal of failed or old sealant

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

Before you send an enquiry

Good information means a firmer quote. When you get in touch, include:

  • Whether the building will be occupied during the work
  • Any dates the work must fit around
  • The asbestos register, for older buildings
  • Drawings or a marked-up plan, if available

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 something else is needed

Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be one of these:

  • Approving the work on behalf of building control
  • Plastic pipes whose detail calls for a collar or wrap
  • Walls or floors that aren’t fire-resisting to begin with

If in doubt, give us a call on 01277 525 020 or send photos by email and we will say what we think.

Joints and surfaces we work on

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

From enquiry to sign-off

On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself typically taking anything from one day to a planned run of visits, depending on the number of seals and the access. If neighbouring businesses or buildings around Broadbridge Heath need work too, visits can be combined. Mention the building’s opening times and we will work within them.

  1. We ask for the product and detail your designer has specified.
  2. Openings are measured and grouped by detail.
  3. Old or wrong materials are cut out.
  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. We walk the completed areas with you and confirm the records agreed at quote stage.

Preparing the site

  • Tell us what induction or permit system the site runs
  • Clear stock, furniture or equipment away from the joints
  • Send your site hours and access windows

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to speak to us on 01277 525 020 or send details through our quote form with what you know.

Fire-rated sealing for Broadbridge Heath buildings

There are several hotels within about 2 miles of Broadbridge Heath. In hotels, bedroom and corridor walls are normally fire-resisting, so services added in a refit need sealing with the specified product. Fire stopping of openings and penetrations in England falls under 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. We install whatever has been specified, to the product’s tested detail.

In a building such as St. John's Church, any service penetration through a fire-resisting wall should be sealed to the specified detail. Refits at places like Broadbridge Retail Park (to the east of Broadbridge Heath) often reroute services through walls between units.
