How we handle fire stopping in Matching

For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, speak to us on 01277 525 020 or email us with the schedule or marked-up drawings and the specified product data. Tell us what records you need and we’ll confirm with the quote. Site teams most often ask us about old intumescent sealant that has split away and snag lists that include open service penetrations, on cable penetrations, joints between fire-resisting walls and floors and pipe penetrations. For commercial sealant work in Matching, you deal with one contact from quote to sign-off, whether it’s one building or several.

Around smaller places like Matching, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

The 12-month guarantee covers our workmanship: 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.

Penetration seals near Matching

Matching lies roughly 23 miles out from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls. For England, the fire stopping of penetrations is dealt with in Approved Document B. 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. What we install is set by the specification, and it goes in to the tested detail.

On a site such as Allen House Business Centre, 2.5 miles north-west of Matching, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product. On a hospital site such as Princess Alexandra Hospital, 4.9 miles west of Matching, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits. Halls and meeting rooms at places like Parish Church of St Mary sometimes gain new services, and any compartment wall crossed needs the specified seal.

Matching is about 4 miles east of Harlow, in Essex. Businesses, contractors and managing agents in Matching use us for work on service penetrations. Matching is one of 644 places in Essex on our list. We also cover London, some 23 miles away.

Sites close to Matching are covered too, including Newman's End (1 mile north), Matching Tye (1 mile south-west), Housham Tye (1 mile south-west), Loyter's Green (1 mile south) and Magdalen Laver (2 miles south).

Quoting for work in Matching

These are the things that shape the price:

  • Any access equipment needed
  • Whether old sealant has to be cut out first
  • Induction, permit and paperwork requirements
  • Whether the work must be split into stages

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

Before you send an enquiry

We can often quote from photographs and a few details. Please tell us:

  • Your programme or deadline
  • Specification clauses that apply
  • The site address and postcode
  • The type of building and who uses it

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to give us a call on 01277 525 020 or send details through our quote form.

Our process

Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact. If others near Matching need work, visits can be combined. You’ll have a fixed quote before work starts.

  1. First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  4. We fit the backing the detail asks for, to the stated depth.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

Preparing the site

  • Share the asbestos register for older buildings
  • Arrange parking or a loading space
  • Clear stock, furniture or equipment away from the joints

Advice

When something else is needed

Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:

  • Large openings beyond what any sealant detail covers
  • Issuing fire ratings or certificates for seals
  • Fire doors, dampers or other fire safety equipment

If in doubt, call the office on 01277 525 020 or send details through our quote form and we will say what we think.

Surfaces we seal

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

Building owners, agents and FMs in Matching

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

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 Matching can sit alongside others in a wider programme.

Questions we’re asked in Matching

What happens to BS 476 references for fire stopping in Matching?

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. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

Is Matching off your patch?

No. Places such as Matching are covered as much as the big towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

What happens if old sealant might contain asbestos?

The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

Are you CHAS accredited and on Constructionline?

Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

Do you guarantee your work?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

Do you have public liability insurance?

Yes. We’re fully insured, and the certificate can go with your quote.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

Maintenance after handover

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

  • Get seals inspected before ceilings and boxing close
  • Don’t let anyone top up a fire seal with the wrong product
  • Leave fire sealant to cure fully before covering it
  • Put resealing into every M&E and fit-out package

Give the sealant its full cure time before ceilings, boxing or decoration go over it. Some fire-rated sealants accept paint and some don’t, and the data sheet says which.

Specify fire stopping early on refits, not as an afterthought. The designer can then choose details that suit the services planned, and the work runs in step with the M&E.

What the job involves on each surface

Small ducts

Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Bigger ducts and fire-resisting ductwork are normally handled with other products, and we’ll say if that applies.

Masonry and concrete

Openings through concrete vary from tidy cores to rough break-outs. The gap is measured at the widest point so we know it sits within the tested range, and any outside it are raised with you.
