Compartment walls and floors in Cliffe Woods

At about 26 miles from central London, Cliffe Woods is within reach of the capital. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls, and the gaps need sealing with the specified product. In England, Approved Document B covers fire stopping of openings and penetrations. 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. What we install is set by the specification, and it goes in to the tested detail.

Where a unit on an estate such as Nuralite Industrial Estate, 2.2 miles to the west of Cliffe Woods, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail. Theatres, wards and plant rooms at sites like French Hospital, 3.1 miles to the south of Cliffe Woods, all have compartment walls crossed by services. Schools such as Cliffe Woods Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.

Cliffe Woods is about 3 miles north of Rochester, in Medway. We send applicators to Cliffe Woods for service penetrations, handled exactly as we handle every other area. Our Medway coverage takes in 54 places. For work in that direction, see our London page, about 26 miles away.

If you need fire stopping in ME3, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed.

Fire stopping in Cliffe Woods, done properly

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. A rating such as EI 60 only holds when the product is installed as it was tested. So our job is to reproduce that arrangement faithfully. The enquiries we see most involve non-fire-rated filler around services and fire-stopping items raised at inspection or handover, on linear gaps at wall heads, pipe penetrations and service gaps in risers. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Cliffe Woods it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Rural conversions around Cliffe Woods 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.

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.

Building owners, agents and FMs in Cliffe Woods

For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

How the job changes by 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.

Metal pipes

Metal pipes conduct heat, so their details often call for extra measures along the pipe, and some details add wrapping or a set length of insulation. We follow whatever the detail requires and flag anything we can’t match.

Why it’s worth doing now in Cliffe Woods

An improvised seal can look finished while offering no tested performance. The fix is to remove it and reinstall to the detail. Around Cliffe Woods, it’s better to renew all the failing joints at once, rather than one at a time. Send photos of each area and we will quote for the lot.

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Why clients in Cliffe Woods choose us

  • CHAS accredited
  • Fully insured
  • Sealing commercial buildings since 2005
  • Joints cleaned back to sound surfaces

Our process

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. For work around Cliffe Woods, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. We ask for the product and detail your designer has specified.
  2. We sort the openings by the detail each one needs.
  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.

Before we start on site

  • Confirm the product named in the specification
  • For older buildings, check the asbestos register before work
  • Let building users know which areas are affected

Advice

FAQs: Cliffe Woods

What happens to BS 476 references for fire stopping in Cliffe Woods?

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. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.

Does your area include sites such as Nuralite Industrial Estate, near Cliffe Woods?

Yes, sites like Nuralite Industrial Estate are within our area, along with the rest of Cliffe Woods. To start, just ring 01277 525 020 or email us with the unit, the joints involved and your access times.

Does the weather affect the work?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, tell us and we will confirm them with the quote.

What will the job cost?

We don’t publish prices, because every site is different. Send photographs or drawings and we will price it at a fixed figure.

What if there’s asbestos in the old mastic?

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

Do you work in Cliffe Woods?

Yes. Sites across Cliffe Woods are covered, with one number for every area we cover.

How the quote is worked out

There’s no standard rate for sealant work, because every site is different. What we take into account:

  • Joint width, depth and condition
  • Working within restricted access windows
  • Specialist products, such as fire-rated or hygienic sealants
  • How accessible the joints are

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

Sending details for a quote

A good diagnosis starts with the right details. Tell us:

  • Any dates the work must fit around
  • The type of building and who uses it
  • Whether an asbestos survey exists
  • Specification clauses that apply

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or send details through our quote form.

What sealant work can’t fix

Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is any of the following:

  • Large openings beyond what any sealant detail covers
  • Issuing fire ratings or certificates for seals
  • Writing the fire-stopping specification

If in doubt, call the office on 01277 525 020 or email drawings and photos and we’ll say what we think.

Joints and surfaces we work on

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