Fire stopping in Marley

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

Site staff or a sealant specialist?

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

How we handle fire stopping in Marley

A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls, and they are easy to forget. Those on your schedule are closed with the specified product. If you are dealing with old intumescent sealant that has split away and open linear gaps along the top of fire-resisting walls, we can put it right. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Marley is the same: the right product in a properly prepared joint.

Rural conversions around Marley 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.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

How a job runs

Tell us your site hours and access windows and we’ll plan around them. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Smaller jobs around Marley can be grouped with others nearby. You’ll have a fixed quote before work starts.

  1. First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. We fit the backing the detail asks for, to the stated depth.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Before we start on site

  • Clear stock, furniture or equipment away from the joints
  • Share your working hours and any access restrictions
  • Tell us what induction or permit system the site runs

Request a quote

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.

How the quote is worked out

The price varies from site to site. Expect it to depend on:

  • The product specified
  • Whether old sealant has to be cut out first
  • Backing rod, priming and other preparation
  • Access and working height

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

What we need to price the job

However big the job, the same details help:

  • The site address and postcode
  • What the building is and how it’s used
  • When you need the work done
  • Rough lengths or quantities, or drawings if you have them

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, ring 01277 525 020 or email a schedule or drawings.

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.

As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

When it isn’t the sealant

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Walls or floors that aren’t fire-resisting to begin with
  • Large openings beyond what any sealant detail covers
  • Deciding what a wall or floor needs, which belongs to the designer

If in doubt, call the office on 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.

Joints and surfaces we work on

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

FAQs: Marley

Can you take on a job at a hospital such as Kent and Canterbury Hospital?

Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.

Is a smaller place like Marley outside your area?

No. Places such as Marley are covered as much as the big towns. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Does weather matter for sealant work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Can you send site paperwork?

Each site asks for different documents, so tell us what you need and we will confirm it when we quote.

Is sealant suitable for all service openings?

No. A sealant’s evidence covers set services, gaps and wall or floor types. Outside that, a different product is needed.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

Do you work to architects’ specifications?

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

Where services cross fire walls in Marley

Marley lies roughly 57 miles out from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls. Fire stopping of openings and penetrations in England falls under Approved Document B. 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. We install whatever has been specified, to the product’s tested detail.

For an estates team at a campus like University for the Creative Arts (4.8 miles north of Marley), summer M&E works are typically followed by a round of penetration sealing. Theatres, wards and plant rooms at sites like Kent and Canterbury Hospital (4.3 miles north-west of Marley) all have compartment walls crossed by services. Older community buildings such as Church of St Giles that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Leave it or put it right?

Fire stopping is a regular point raised at inspections and handover. Finding unsealed or improvised openings late can hold up a programme, so earlier action pays back. For buildings around smaller places like Marley, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
