Fire stopping in Furzeley Corner

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

When something else is needed

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

  • Openings that need collars, wraps, batts or boards rather than sealant
  • Construction that lacks the fire resistance the seal relies on
  • Fire doors, dampers or other fire safety equipment

If in doubt, phone 01277 525 020 or email us and we will say what we think.

Surfaces we seal

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

Fire stopping in Furzeley Corner

It helps to set out our role at the start. Deciding the specification sits with the designer, the fire engineer and building control; sign-off sits with them too. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance on buildings around Furzeley Corner. We work on service gaps in risers, small duct penetrations where the tested detail allows and cable penetrations, and the failures we’re asked to look at most are seals disturbed by maintenance and left open and unsealed joints where partitions meet the slab. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Furzeley Corner, that means joint design, primers and backing rod as standard.

Barn and farm-building conversions near places like Furzeley Corner often combine new partitions with old walls. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

How a job runs

Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. Rural sites near Furzeley Corner may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. We start with your penetration schedule, drawings or specification.
  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. Unsuitable material is removed and the opening cleaned first.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. Anything outside the detail is reported to you rather than sealed.

Before we start on site

  • Warn occupants and staff about the work
  • Send your site hours and access windows
  • Let us know about inductions and permits

Getting a fixed quote

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to ring 01277 525 020 or send details through our quote form with what you know.

Keeping the joints sound

Cleaning and maintenance staff play a part too. Share these points with them:

  • Keep product data and details in the fire safety file
  • Don’t let anyone top up a fire seal with the wrong product
  • Ask the designer to confirm details early on refits
  • Look above ceilings when tiles are lifted for other jobs

After the work, brief anyone else working in the area that the openings are now sealed. Any seal cut back for a new service needs reinstating to its tested detail.

A simple record of seal locations and products helps. When a new service goes through, everyone knows which product and detail to match, which saves guesswork.

When to call us in Furzeley Corner

Most open service penetrations are left by later work. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser leaves an opening that nobody returns to. Across several fit-outs, the openings add up.

Most enquiries start with one or more of the following:

  • Openings left by services added after handover
  • Old intumescent sealant that has split away
  • Builders’ foam or ordinary silicone in compartment walls
  • Hidden openings found during inspections

Office fit-outs on sites such as Parklands Business Park, less than half a mile to the north of Furzeley Corner, add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it.

Choosing a commercial sealant contractor

Surface by surface

Risers and ceiling voids

Openings above suspended ceilings are easy to miss. We follow your schedule area by area, and note anything we find that isn’t on it.

Linear joints

Head-of-wall joints often have to absorb slab deflection. We use the product and backing the detail names for that movement, with no gaps along the run.

Questions we’re asked in Furzeley Corner

How does the move away from BS 476 affect penetration seals in Furzeley Corner?

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. Our part doesn’t change: the specified product, to its tested detail.

Is a hospital such as Queen Alexandra Hospital somewhere you can work?

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.

How soon can the area be used again?

We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.

Can you fit around our working hours?

Give us your site hours and any access windows in your enquiry, and we’ll schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

Is colour matching possible?

It depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

Is your workmanship covered by a guarantee?

Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.
