Where services cross fire walls in Woolmer Hill

Central London is about 41 miles from Woolmer Hill. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls. For England, the fire stopping of penetrations is dealt with in Approved Document B. 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. What we install is set by the specification, and it goes in to the tested detail.

In a building such as St Paul, any service penetration through a fire-resisting wall should be sealed to the specified detail. For a hospital such as Holy Cross Hospital (0.9 miles north-east of Woolmer Hill), penetration sealing is usually phased ward by ward, with infection-control rules agreed first.

Woolmer Hill is about 1 mile south-west of Haslemere, in West Sussex. Our applicators travel to Woolmer Hill for work on service penetrations. Across West Sussex, 373 places are covered, Woolmer Hill among them. Our Portsmouth page has more on work in that area.

Fire stopping in Woolmer Hill, done properly

Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4 and the results are classified to BS EN 13501-2. A rating such as EI 60 only holds when the product is installed as it was tested. Reproducing the tested arrangement on site is the part we take care of. Site teams most often ask us about service penetrations left open after M&E works and fire seals cut back for extra cables and never reinstated, on small duct penetrations where the tested detail allows, service gaps in risers and cable penetrations. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Woolmer Hill, that means joint design, primers and backing rod as standard.

Smaller places such as Woolmer Hill still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Do you need fire stopping in Woolmer Hill?

Plenty of openings were simply never closed because they sat out of sight above a ceiling or inside a riser. Inspections, refurbishments and ceiling access typically bring them to light.

Look out for the following:

  • Fire-stopping items raised at inspection or handover
  • Damaged fire seals in risers and voids
  • Openings left by services added after handover
  • Open linear gaps along the top of fire-resisting walls

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

Questions to ask before you appoint anyone

Woolmer Hill: questions and answers

What happens to BS 476 references for fire stopping in Woolmer Hill?

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.

Will you take on work at estates like Kings Road Industrial Estate, close to Woolmer Hill?

Yes. We cover Woolmer Hill and the area around it, including industrial estates, business parks and retail parks such as Kings Road Industrial Estate. A few photographs and the unit address let us price the work.

Do you hold CHAS accreditation?

Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

Does the weather affect the work?

Outside, 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.

Can the building stay open while you work?

In most cases, yes. Phased work can be planned so areas stay in use.

What happens if old sealant might contain asbestos?

The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

Will your applicators have CSCS cards?

Yes. We use CSCS-carded applicators.

How a job runs

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before the next one starts. Jobs in and around smaller places like Woolmer Hill are normally planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. The specification and schedule come first, so we know which details apply.
  2. Access, permits and the order of areas are agreed with the site team.
  3. We compare every service penetration with its tested detail before sealing.
  4. Foam, ordinary sealant and debris come out first.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

What we need from you

  • Send any specification or drawings in advance
  • For older buildings, check the asbestos register before work
  • Tell staff and tenants when we will be in

When something else is needed

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Issuing fire ratings or certificates for seals
  • Fire doors, dampers or other fire safety equipment
  • Plastic pipes whose detail calls for a collar or wrap

If in doubt, ring 01277 525 020 or send photos by email and we will say what we think.

Where we work in Woolmer Hill

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

Should maintenance staff do it?

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.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Owners, agents and contractors

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Cost factors for service penetrations

Each job is priced on its own details. The things that drive the figure:

  • The total length or number of joints
  • Induction, permit and paperwork requirements
  • Backing rod, priming and other preparation
  • How much existing material needs removing

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

What to include in your enquiry

It doesn’t need to be a full survey. These details are enough to start:

  • The asbestos register, for older buildings
  • Anything awkward about access or site hours
  • Whether the building will be occupied during the work
  • The site address and postcode

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.
