Fire stopping across Farley Hill

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Fire stopping in Farley Hill

Opened ceilings and riser doors often reveal service openings nobody sealed. If a specification already covers those walls and floors, we can reseal to it using the product and detail it sets out. Where there isn’t one, the designer or fire engineer needs to set one first. We work on pipe penetrations, joints between fire-resisting walls and floors and linear gaps at wall heads, and the usual reasons a site gets in touch are seals that don’t match their tested detail and fire sealant pulled out of the opening. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Farley Hill, preparation and product choice get the time they need.

For a smaller site near Farley Hill, we plan to do all the penetrations in one go, with the specification and photos sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What we can’t put right

Honesty saves time and money. Fresh joints won’t solve:

  • Writing the fire-stopping specification
  • Issuing fire ratings or certificates for seals
  • Fire risk assessments, a job for a competent assessor

Not sure which it is? You can give us a call on 01277 525 020 or send details through our quote form and we will tell you honestly before you book.

What we seal

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

What affects the price in Farley Hill

What shapes the price:

  • Removal of failed or old sealant
  • The site’s rules and procedures
  • Which sealant the job calls for
  • Joint width, depth and condition

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Sending details for a quote

Diagnosis starts before we arrive. Let us know:

  • The asbestos register, for older buildings
  • The site address and postcode
  • A wide shot and a close-up of the area
  • Any dates the work must fit around

For a fixed quote, call 01277 525 020 or email us with the site address and an outline of the work. You can also send details through our quote form.

How a job runs

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself typically taking longer where risers, ceiling voids or occupied floors have to be worked through in sequence. Jobs in and around smaller places like Farley Hill are normally planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  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. 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. Completed areas are checked with you, with the records agreed when we quoted.

Before we start on site

  • Clear stock, furniture or equipment away from the joints
  • Confirm the product named in the specification
  • Share the asbestos register for older buildings

Surface by surface

Small ducts

Some fire-rated sealant details cover small ducts. Larger or fire-rated ductwork usually needs a different solution set by the designer and we flag that rather than guess.

Risers and ceiling voids

Risers and ceiling voids hold most of a building’s service penetrations. Access is often tight, so we agree it with you in advance.

Looking after the joints

Once the work is signed off, these steps help:

  • Keep general-purpose fillers away from compartment walls
  • Treat an open penetration as a priority repair
  • Check with the data sheet before painting over fire sealant
  • Check risers and ceiling voids after each round of works

Never top up a fire seal with foam, ordinary silicone or filler. Repairs need the same product and detail as the original, or a new specification from the designer.

A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate, and it helps at inspections.

Compartment walls and floors in Farley Hill

Farley Hill lies roughly 36 miles out from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls. For England, the fire stopping of penetrations is dealt with in Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Either way, we install the specified product to its tested detail.

Campus buildings at universities such as University of Reading - Whiteknights Campus, 4.8 miles north of Farley Hill, see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified. For a school such as Farley Hill Primary School, penetration sealing fits best at the end of the summer works.

Do you need fire stopping in Farley Hill?

On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is when untested combinations creep in, which then have to be put right.

Any of the following is a good reason to get the joints checked over:

  • Fire seals cut back for extra cables and never reinstated
  • Service penetrations left open after M&E works
  • Snag lists that include open service penetrations
  • Fire stopping installed outside its tested range

On estates like Hogwood Lane Industrial Estate, 1 mile east of Farley Hill, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.

Questions about Farley Hill

Is Farley Hill too far out for you?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Can you work around term dates at a campus such as University of Reading - Whiteknights Campus?

Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

Do you need to see the site first?

That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.

Do you design or specify fire stopping?

No, that isn’t our role. With the designer’s details in hand, we can price the sealant elements and point out anything needing another product.

Will you just go over the old sealant?

No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

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; installing to the detail is what carries that across to site.
