About our fire stopping in Willingale

Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. A rating such as EI 60 only holds when the product is installed as it was tested. Reproducing the tested arrangement on site is the part we take care of. We work on small duct penetrations where the tested detail allows, linear gaps at wall heads and joints between fire-resisting walls and floors, and the failures we’re asked to look at most are fire-stopping items raised at inspection or handover and unsealed openings around new pipes and cables. For commercial sealant work in Willingale, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Around smaller places like Willingale, 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.

Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Willingale: questions and answers

Can work at a site such as Writtle University College Cow Watering Campus fit around teaching?

Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

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

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.

Can staff carry on working while you are here?

Normally, yes. We phase the work so most of the building stays in use.

Do you cover Willingale?

Yes. Sites across Willingale are covered, and the same phone number covers every area.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

What happens if old sealant might contain asbestos?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

Can you work to our specification?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

What the job involves on each surface

Plastic pipes

Plastic pipes soften and collapse in a fire. Some intumescent sealants are tested on smaller plastic pipes, but many need a collar or wrap. We confirm material and size first and tell you if sealant isn’t the right product.

Linear joints

Head-of-wall joints often have to absorb slab deflection. The specified product and backing for that movement are what goes in.

Doing it in-house

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Aftercare for building managers

Keep the joints in good shape with a few simple steps:

  • Treat an open penetration as a priority repair
  • Ask which product is in place before decorating
  • Ask the designer to confirm details early on refits
  • Record which product was used where

Store the specified product details somewhere the next contractor can find them. It makes later repairs much easier to match.

A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate, which saves guesswork.

Compartments and services around Willingale

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. What we install is set by the specification, and it goes in to the tested detail. Willingale lies roughly 24 miles out from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls; the gaps need the specified seal.

In a building such as Parish Church of St Christopher Willingale Doe, any service penetration through a fire-resisting wall should be sealed to the specified detail. Campus buildings at universities such as Writtle University College Cow Watering Campus (4.1 miles east of Willingale) see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified.

Willingale is about 7 miles west of Chelmsford, in Essex. We cover commercial sites throughout Willingale. Across Essex, 644 places are covered, including Willingale. Sites around London have their own page, roughly 24 miles from Willingale.

How the quote is worked out

The price varies from site to site. It mainly depends on:

  • Joint width, depth and condition
  • Travel to remote or island sites
  • Access and working height
  • Working within restricted access windows

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

What to include in your enquiry

However big the job, the same details help:

  • Your programme or deadline
  • Clear photos of the problem areas
  • The product your specification calls for
  • The site address and postcode

The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or call the office on 01277 525 020 or email the details over if you’d rather talk the job through.

How a job runs

Before we leave any area, we remove the tape, clean down and inspect every joint. Where the sealant needs time to cure before use, we tell you and sign the area. Jobs in and around smaller places like Willingale are typically planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. First we confirm the product and tested details named in the specification.
  2. Openings are measured and grouped by detail.
  3. Improvised fillers and failed sealant are removed.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Preparing the site

  • Make sure the joints can be reached
  • Tell staff and tenants when we will be in
  • Tell us your opening times and when work is allowed

What sealant work can’t fix

Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:

  • Signing off or certifying a building’s fire stopping
  • Plastic pipes whose detail calls for a collar or wrap
  • Reviewing a building’s overall fire safety

If you’re not sure, just call the office on 01277 525 020 or email us and we’ll give you a straight answer before you book.

Surfaces we seal

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