Service penetrations in Selham buildings

Central London is about 44 miles from Selham. 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. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.

In a building such as Church of St James, any service penetration through a fire-resisting wall should be sealed to the specified detail. Industrial units on estates such as Hampers Common Industrial Estate, 3 miles to the east of Selham, often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal. On a hospital site such as Midhurst Community Hospital, 2.9 miles to the west of Selham, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.

Selham is about 8 miles south of Haslemere, in West Sussex. Commercial clients in Selham use us for work on service penetrations. Selham is one of 373 places in West Sussex on our list for service penetrations. For work in that direction, see our Portsmouth page (21 miles or so).

Fire stopping in Selham

No fire sealant works on its own: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. Before we seal anything, we check the opening against the detail it is meant to follow, and raise it with you if it falls outside. Site teams most often ask us about seals disturbed by maintenance and left open and non-fire-rated filler around services, on small duct penetrations where the tested detail allows, joints between fire-resisting walls and floors and cable penetrations. Most enquiries from Selham start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Rural conversions around Selham can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

Questions we are asked in Selham

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

Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.

Will you take on work at estates like Hampers Common Industrial Estate, close to Selham?

Yes. Our area takes in Selham and its surroundings, with estates and business parks such as Hampers Common Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.

Is your workmanship covered by a guarantee?

Yes. Workmanship is guaranteed for 12 months.

Does weather matter for sealant work?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Which standards are fire seals tested to?

The tests are BS EN 1366-3 for penetrations and BS EN 1366-4 for linear joints, and classification is to BS EN 13501-2. An EI 60 seal kept its integrity and insulation for 60 minutes as tested and the installation has to match the test.

Will you come and look before quoting?

Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.

Do you work to architects’ specifications?

Yes. Send it with your enquiry, and the quote will be based on it.

Cost factors for service penetrations

These are the things that shape the price:

  • Access and working height
  • Travel to remote or island sites
  • Site requirements such as inductions and permits
  • How much existing material needs removing

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Sending details for a quote

However big the job, the same details help:

  • Anything awkward about access or site hours
  • Approximate linear metres or a joint schedule
  • The type of building and who uses it
  • Any dates the work must fit around

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, call the office on 01277 525 020 or email drawings and photos.

On site: what to expect

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Jobs in and around smaller places like Selham are normally planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. First we confirm the product and tested details named in the specification.
  2. We sort the openings by the detail each one needs.
  3. Improvised fillers and failed sealant are removed.
  4. Mineral wool or other backing is fitted where required.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Getting the site ready

  • Agree which areas must stay open
  • Tell us your opening times and when work is allowed
  • Share the asbestos register for older buildings

Quotes

Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

What we can’t put right

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Signing off or certifying a building’s fire stopping
  • Construction that lacks the fire resistance the seal relies on
  • Plastic pipes whose detail calls for a collar or wrap

If you’re not sure, just speak to us on 01277 525 020 or email the details over and we will give you a straight answer.

What we seal

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

Work for main contractors and building owners

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Keeping the joints sound

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Flag new cables with no seal around them
  • Don’t let anyone top up a fire seal with the wrong product
  • Have penetrations checked while they can still be seen
  • Make fire stopping part of every scope that crosses a fire-resisting wall

Allow the manufacturer’s stated cure time before boxing in or decorating. Some fire-rated sealants accept paint and some don’t.

Write fire stopping into the scope of any work crossing a compartment wall or floor. That way the opening is sealed while the trade and access are still there instead of being left for someone else.

Should maintenance staff do it?

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. That’s why many clients bring in a specialist from the beginning.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
