Fire stopping for Holyfield sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Maintenance after handover

To get the most from the new sealant:

  • Brief every trade that openings they make must be sealed
  • Keep product data and details in the fire safety file
  • Treat an open penetration as a priority repair
  • Check risers and ceiling voids after each round of works

After the work, brief anyone else working in the area that the openings are now sealed. If a seal has to be opened for a new service, it should be reinstated to the same detail.

Ask every contractor who works in risers or voids to report openings they create. It costs little and catches breaches early.

Fire stopping in Holyfield

A fire-rated sealant is only one part of a tested system: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. We match each opening to that detail before any sealant goes in. The enquiries we see most involve unsealed openings around new pipes and cables and open linear gaps along the top of fire-resisting walls, across joints between fire-resisting walls and floors, service gaps in risers and small duct penetrations where the tested detail allows. Looking for mastic applicators who cover Holyfield? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Barn and farm-building conversions near places like Holyfield often combine new partitions with old walls. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Fire-rated sealing for Holyfield buildings

At about 15 miles from central London, Holyfield is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls; the gaps need the specified seal. 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. Our part stays the same: the specified product, installed to its tested detail.

Theatres, wards and plant rooms at sites like Cheshunt Community Hospital, 1.8 miles to the west of Holyfield, all have compartment walls crossed by services. For a school such as Turnford School, penetration sealing fits best at the end of the summer works.

Holyfield is about 2 miles north of Waltham Abbey, in Essex. Businesses, contractors and managing agents in Holyfield can call on us for service penetrations. Holyfield is one of 644 places we cover in Essex. Sites around London have their own page, roughly 15 miles from Holyfield.

Work on service penetrations is covered throughout EN9, for business premises of every kind. Just outside Holyfield, we also work in Aimes Green (1 mile east), Breach Barns (1 mile east), Turnford (2 miles north-west), Bumble's Green (2 miles north-east) and Lower Nazeing (2 miles north). Bigger towns within reach include Harlow (6 miles north-east), Brentwood (14 miles south-east), Loughton (5 miles south-east), Epping (5 miles east), Buckhurst Hill (6 miles south) and Chigwell (7 miles south-east).

When to call us in Holyfield

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 can leave the hole behind. Across several fit-outs, the openings add up.

If one of these sounds familiar, it’s time for a closer look:

  • Penetration schedules that need working through
  • Openings left by services added after handover
  • Expanding foam used as fire stopping
  • Hidden openings found during inspections

At a retail site such as Highbridge Retail Park, 1.7 miles to the south-west of Holyfield, walls between units may be fire-resisting, so services added in a refit need the specified seal.

Before you book anyone

  • Will CSCS-carded applicators be on site?
  • Whether old or failed sealant will be cut out, not overlaid
  • Are they CHAS accredited or on Constructionline?
  • What level of public liability insurance do they hold?

How to choose a sealant contractor

What sets the cost

The price varies from site to site. It mainly depends on:

  • Quantities, in metres or numbers
  • The size and state of each joint
  • Removal of failed or old sealant
  • Working within restricted access windows

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

Before you send an enquiry

Whether it’s one area or a whole building, the same details help:

  • Whether an asbestos survey exists
  • Rough lengths or quantities, or drawings if you have them
  • Clear photographs of the problem areas
  • Access details, including height

Need a figure for a tender or a budget? Send the scope and any drawings, and we’ll return a fixed quote that you can work with. For a chat about it beforehand, ring 01277 525 020 or email a schedule or drawings.

Why deal with it now?

An improvised seal can look finished while offering no tested performance. The fix is to remove it and reinstall to the detail, and doing it once, properly, is cheaper. Converted and older buildings near places like Holyfield tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Why clients in Holyfield choose us

  • Fully insured
  • Constructionline member for supplier checks

Could you schedule work at a campus like Hertford College: Broxbourne Campus for the vacation?

What happens to BS 476 references for fire stopping in Holyfield?

References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.

Can one quote cover more than one building?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

How a job runs

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. Rural sites near Holyfield may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  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. Mineral wool or other backing is fitted where required.
  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.

Getting the site ready

  • Clear stock, furniture or equipment away from the joints
  • Explain the parking and delivery arrangements
  • Tell staff and tenants when we will be in

Getting a fixed quote

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

Advice

Should maintenance staff do it?

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
