About our fire stopping in Durford Wood

Facilities managers in Durford Wood often find open service penetrations when ceilings come down for other work. Where the walls and floors already have a fire-stopping specification, we can work to it, matching the product and detail it names. Where there isn’t one, the designer or fire engineer needs to set one first. Site teams most often ask us about fire sealant pulled out of the opening and openings left by services added after handover, on linear gaps at wall heads, joints between fire-resisting walls and floors and small duct penetrations where the tested detail allows. Most enquiries from Durford Wood start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Rural conversions around Durford Wood can put new fire-resisting partitions inside older structures. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.

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’re clear about what is covered before work starts.

When something else is needed

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Openings that need collars, wraps, batts or boards rather than sealant
  • Writing the fire-stopping specification
  • Walls or floors that aren’t fire-resisting to begin with

Not sure which it is? You can phone 01277 525 020 or send photos by email and we’ll tell you honestly before you book.

Surfaces we seal

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

Fire stopping in Durford Wood: the local picture

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. We install whatever has been specified, to the product’s tested detail. Durford Wood lies roughly 47 miles out from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls; the gaps need the specified seal.

For a building such as Church of St Mary, new heating or data runs are the usual reason penetrations need sealing. Industrial units on estates such as Upper Adhurst Industrial Park (0.6 miles south-west of Durford Wood) often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal. Theatres, wards and plant rooms at sites like Petersfield Hospital, 2.8 miles to the south-west of Durford Wood, all have compartment walls crossed by services.

Durford Wood is about 3 miles north-east of Petersfield, in Hampshire. Looking for fire stopping in Durford Wood? We can help, as we do across Hampshire. 723 places across Hampshire fall within our area, including Durford Wood. Portsmouth is covered too, some 17 miles away.

How the job changes by surface

Small ducts

Ducts are only sealed with sealant where the detail allows it. Dampers and ductwork systems themselves are outside our work.

Linear joints

Joints at the top of partitions may need to move as the slab above deflects. We use the product and backing the detail names for that movement.

Aftercare for building managers

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Keep product data and details in the fire safety file
  • Have penetrations checked while they can still be seen
  • Check risers and ceiling voids after each round of works
  • Ask which product is in place before decorating

Give the sealant its full cure time before ceilings, boxing or decoration go over it. Some fire-rated sealants accept paint and some don’t.

Specify fire stopping early on refits, not as an afterthought. Details can then be picked to suit the actual pipes, cables and ducts, and the work runs in step with the M&E.

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. Getting these wrong usually costs more in the end than doing them right.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

From enquiry to sign-off

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. For work around Durford Wood, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. The specification and schedule come first, so we know which details apply.
  2. We plan the sequence of floors, risers and voids with you.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Unsuitable material is removed and the opening cleaned.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

Getting the site ready

  • Share your working hours and any access restrictions
  • Agree which areas must stay open
  • Have the specification and drawings to hand

Advice

Your questions answered

Do you cover business parks and estates near Durford Wood, such as Upper Adhurst Industrial Park?

Yes, sites like Upper Adhurst Industrial Park are within our area, along with the rest of Durford Wood. Photos and a short description are enough for a first look.

Can you take on a job at a hospital such as Petersfield Hospital?

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Is the work guaranteed?

Yes. Our workmanship is backed for 12 months on every job.

Will you sign off the seals for us?

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, and any records you need can be confirmed with the quote.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.

Is BS 476 being phased out?

For buildings in England, Approved Document B removes BS 476 references from 2 September 2029. Products are then judged on BS EN 13501-2 classifications. In Scotland, the Technical Handbook sets its own guidance.
