Fire stopping in Great Hollands, done properly

Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4 and the results are classified to BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. Most enquiries involve non-fire-rated filler around services and fire sealant pulled out of the opening, across cable penetrations, joints between fire-resisting walls and floors and linear gaps at wall heads. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Great Hollands, that means joint design, primers and backing rod as standard.

Buildings in a smaller place such as Great Hollands that need fire-rated sealing are typically schools, care homes, surgeries, small offices and flats over shops. Specified fire-rated sealant goes around new services there, built to match the manufacturer’s detail.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Doing it in-house

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Putting right a botched joint often costs more than sealing it well at the start, 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.

What sets the cost

Before we quote, we look at:

  • The site’s rules and procedures
  • Working within restricted access windows
  • Joint width, depth and condition
  • Whether old sealant has to be cut out first

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

Sending details for a quote

To price the job accurately, we need a clear picture of the site. Send us:

  • The product your specification calls for
  • Where the site is, with the postcode
  • Any dates the work must fit around
  • Approximate linear metres or a joint schedule

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

On site: what to expect

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. For a job in Great Hollands, the main thing is a clear picture of the work, so send photos of each area. You will then get a fixed price for the work.

  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. Each opening is checked for wall or floor type, service, gap and depth.
  4. Unsuitable material is removed and the opening cleaned.
  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.

Getting the site ready

  • Make sure the joints can be reached
  • Point out parking and an unloading spot
  • Send any specification or drawings in advance

Different surfaces, different methods

Masonry and concrete

Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest against the detail’s limits, and any that don’t are flagged.

Small ducts

Ducts are only sealed with sealant where the detail allows it. Dampers and ductwork systems themselves are outside our work.

For managing agents and facilities managers

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Great Hollands can sit alongside others in a wider programme.

What we’re called out for in Great Hollands

Some seals fail because the wrong product went in: builders’ foam or ordinary silicone used to fill a hole. The opening looks sealed but has no fire test evidence behind it.

Typical triggers for a call:

  • Fire sealant pulled out of the opening
  • Openings left by services added after handover
  • Non-fire-rated filler around services
  • Unsealed joints where partitions meet the slab

For a hospital such as Broadmoor Hospital (2.1 miles south of Great Hollands), penetration sealing is normally phased ward by ward, with infection-control rules agreed first.

Questions to ask before you book

  • How the existing material will be dealt with
  • Who will actually carry out the work
  • How they handle RAMS and site documents
  • How joint depth will be controlled

How to choose a sealant contractor

Compartments and services around Great Hollands

A good number of hotels sit less than 2 miles from Great Hollands. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail. Central London is about 30 miles from Great Hollands. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls; the gaps need the specified seal.

On estates like Longshot Lane Industrial Estate, 1 mile north of Great Hollands, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal. For a building such as St Michael and St Mary Magdalene's Church, new heating or data runs are the usual reason penetrations need sealing.

Questions about Great Hollands

Will you take on work at estates like Longshot Lane Industrial Estate, close to Great Hollands?

Yes. Our area takes in Great Hollands and its surroundings, with estates and business parks such as Longshot Lane Industrial Estate included. A few photographs and the unit address let us price the work.

Will you plan work around the academic year at somewhere like Newbold College of Higher Education?

Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Do you approve fire stopping for building control?

No. We don’t certify or sign off fire stopping, and we hold no third-party fire-stopping installer certificate. Our part is fitting the specified product to its tested detail, and any records you need can be confirmed with the quote.

Does the weather affect the work?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Are you insured?

Yes. Our insurance certificate can be sent alongside the quote.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

Is fire stopping in Scotland covered by different guidance?

Scotland sets its own building regulations, with Technical Handbooks. Wherever the site is, our work follows the specification and the tested detail.
