Fire stopping in Gambles Green

Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. We work to the product’s tested detail for every seal. Most enquiries involve head-of-wall gaps with no fire seal and service penetrations left open after M&E works, on small duct penetrations where the tested detail allows, service gaps in risers and cable penetrations. For commercial sealant work in Gambles Green, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Around smaller places like Gambles Green, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.

A 12-month guarantee applies to all our work. Should something we installed fail, give us a call on 01277 525 020 or email the details over and we’ll come back to it.

Commercial clients in Gambles Green

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first.

What we can’t put right

Not every problem is a sealant problem, and we’re upfront when that’s the case. These need a different solution:

  • Approving the work on behalf of building control
  • Plastic pipes whose detail calls for a collar or wrap
  • Writing the fire-stopping specification

If you’re not sure, just phone 01277 525 020 or email the details over and we’ll give you a straight answer before you book.

Surfaces we seal

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

Gambles Green: questions and answers

Is Gambles Green off your patch?

Not at all. Gambles Green is within our area. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Is a hospital such as Broomfield Hospital somewhere you can work?

Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

How long does a job like this take?

That varies with the scale of the job, but the work typically takes anything from one day to a planned run of visits, depending on the number of seals and the access. For bigger or phased jobs, we will set out a timescale with the quote.

Are you members of a third-party fire-stopping installer scheme?

No. We are not members of a third-party fire-stopping installer scheme. Our credentials are CHAS accreditation, Constructionline membership and CSCS-carded applicators, and we are fully insured. Where a client or main contractor requires a scheme member, we’ll say so right away rather than waste your time.

How long before the joints can be used?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.

What about RAMS and site documents?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.

Will you quote for a small job?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

How a job runs

We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you. Jobs in and around smaller places like Gambles Green are typically planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.

  1. The specification and schedule come first, so we know which details apply.
  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. We tell you about openings that need a different product.

Preparing the site

  • Let building users know which areas are affected
  • Point out parking and an unloading spot
  • Flag any permit to work we’ll need

Keeping the joints sound

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Keep product data and details in the fire safety file
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Ask which product is in place before decorating
  • Arrange inspection before areas are covered up

Once the seals are in, tell other trades they exist and must not be disturbed. If a seal has to be opened for a new service, it should be reinstated to the same detail.

Regular walk-rounds of service areas are worth the time. Catching a damaged seal early keeps the fix small; found late, it can be one of many.

How the quote is worked out

Your fixed quote is built from the real scope. It takes account of:

  • Removal of failed or old sealant
  • Any access equipment needed
  • The product specified
  • The size and state of each joint

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 we will put a fixed figure on it.

Before you send an enquiry

Diagnosis starts before we arrive. Let us know:

  • Any dates the work must fit around
  • Photos of the joints, close up and from further back
  • Whether an asbestos survey exists
  • The postcode of the building

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.

Service penetrations in Gambles Green buildings

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. We install whatever has been specified, to the product’s tested detail. At about 35 miles from central London, Gambles Green is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls, and the gaps need sealing with the specified product.

Holiday works at schools like Terling Church of England Voluntary Aided Primary School often leave service openings to seal before pupils return. For a building such as United Reformed Church, new heating or data runs are the usual reason penetrations need sealing. Large healthcare estates like Broomfield Hospital (to the south-west of Gambles Green) change their services often, so penetration seals are worth checking after M&E work.

Gambles Green is about 3 miles west of Witham, in Essex. We send applicators to Gambles Green for service penetrations, handled exactly as we handle every other area. 644 places across Essex fall within our area, Gambles Green among them.

Surface by surface

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.

Masonry and concrete

Many seals are made in blockwork, brickwork or concrete slabs. Dust and loose debris are cleared out of the opening, so the sealant and any backing sit properly.
