How we handle fire stopping in Foxash Estate

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 part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. We work to the product’s tested detail for every seal, not a rule of thumb. Most enquiries involve expanding foam used as fire stopping and openings left by services added after handover, on cable penetrations, linear gaps at wall heads and pipe penetrations. Whether you call it commercial sealant work, mastic application or joint sealing, in Foxash Estate it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Rural conversions around Foxash Estate can put new fire-resisting partitions inside older structures. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.

Every job we finish is backed by a 12-month workmanship guarantee, in Foxash Estate as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Site staff or a sealant specialist?

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Fire stopping in Foxash Estate: the local picture

Fire stopping of openings and penetrations in England falls under Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements.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. There are several hotels within about 2 miles of Foxash Estate. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.

Residences at universities like University of Essex, 4.7 miles south-west of Foxash Estate, have compartment walls that must be resealed whenever services change. Hospital estates such as Colchester Hospital, 4.9 miles west of Foxash Estate, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. Older community buildings such as Church of St Mary that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Foxash Estate is about 6 miles north-east of Colchester, in Essex. Across the CO11 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. 644 places across Essex fall within our area, including Foxash Estate.

From enquiry to sign-off

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For a building around Foxash Estate, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  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. Improvised fillers and failed sealant are removed.
  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

  • Tell staff and tenants when we’ll be in
  • For older buildings, check the asbestos register before work
  • Point out parking and an unloading spot

Advice

Keeping the joints sound

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

  • File the specified details where the next contractor can find them
  • Get seals inspected before ceilings and boxing close
  • Foam or ordinary sealant is never a fire-seal repair
  • Look above ceilings when tiles are lifted for other jobs

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.

The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. That way the opening is sealed while the trade and access are still there instead of being left for someone else.

Foxash Estate: questions and answers

Can you work around term dates at a campus such as University of Essex?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Can you work at a site such as Martells Industrial Estate, by Foxash Estate?

Yes. We cover Foxash Estate and the area around it, including industrial estates, business parks and retail parks such as Martells Industrial Estate. Photos and a short description are enough for a first look.

Is your workmanship covered by a guarantee?

Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.

Can you seal any opening with fire-rated sealant?

No. It depends on the tested detail for that wall or floor and service. Large openings, many plastic pipes and some ducts need collars, wraps, batts or boards, and we will tell you when that applies.

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.

What changes on 2 September 2029?

For buildings in England, Approved Document B removes BS 476 references from 2 September 2029. Classification to BS EN 13501-2 becomes the expected evidence. In Scotland, the Technical Handbook sets its own guidance, with clause 2.1.14 covering service penetrations.

Is any job too small?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Honest limits

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Issuing fire ratings or certificates for seals
  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Openings that need collars, wraps, batts or boards rather than sealant

If you’re not sure, just call 01277 525 020 or email a schedule or drawings and we will give you a straight answer.

What we seal

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

Cost factors for service penetrations

These are the things that shape the price:

  • Backing rod, priming and other preparation
  • How accessible the joints are
  • Site requirements such as inductions and permits
  • Location, for remote and island sites

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.

Sending details for a quote

To price the job accurately, we need a clear picture of the site. Useful things to include:

  • Whether an asbestos survey exists
  • The postcode of the building
  • The type of building and who uses it
  • Any dates the work must fit around

A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or speak to us on 01277 525 020 or use the quote form to discuss it first.

Different surfaces, different methods

Small ducts

We seal around ducts only within what the tested detail covers. Dampers and ductwork systems themselves are outside our work.

Risers and ceiling voids

Openings above suspended ceilings are easy to miss. We follow your schedule area by area, and note anything we find that isn’t on it.
