Fire stopping in Billericay

A fire-rated sealant is only one part of a tested system: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. We match each opening to that detail before any sealant goes in, and raise it with you if it falls outside. We work on cable penetrations, pipe penetrations and service gaps in risers, and the usual reasons a site gets in touch are old intumescent sealant that has split away and non-fire-rated filler around services. Most enquiries from Billericay start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Towns the size of Billericay have plenty of buildings with compartment walls: schools, care homes, surgeries, offices and blocks of flats. New cabling or pipework through a fire-resisting wall leaves a gap that has to be made good with the specified product.

Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Penetration seals near Billericay

Billericay lies roughly 24 miles out from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls; the gaps need the specified seal. Approved Document B is the English guidance that covers fire stopping around 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.

Older community buildings such as Church of St Mary Magdalene that have been rewired or given new heating can have service gaps through walls worth checking against the specification. Hospital estates such as Mayflower Community Hospital, 0.9 miles to the south-west of Billericay, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.

Billericay is about 4 miles north of Basildon, in Essex. Commercial clients in Billericay use us for work on service penetrations, as part of our coverage of Essex. Across Essex, 644 places are covered, Billericay among them. There’s a separate page for London, about 24 miles away.

Building owners, agents and FMs in Billericay

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first.

CHAS accredited and a Constructionline member, we’re straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.

Your questions answered

Do you take on work at healthcare sites like Mayflower Community Hospital?

Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Do you design the fire stopping for buildings in Billericay?

No, that sits with the designer, fire engineer or building control. We install what’s specified, to the product’s tested detail.

Can you work while the building is occupied?

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

How do you choose the sealant?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Can you quote from photos?

Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we will arrange a visit before quoting.

How long does a job like this take?

That varies with the scale of the job, but the work typically takes a single visit for a short list of penetrations, or a phased programme for a whole building. Larger or phased jobs take longer, and we will give you a timescale with the quote.

What hours do you work?

Give us your site hours and any access windows in your enquiry, and we will plan around them. Our office runs Monday to Friday, 8am until 5pm.

On site: what to expect

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. If you have more than one building in Billericay, they can often be done on the same visit, with one quote covering them. Give us your access times and we will fit the work in.

  1. We ask for the product and detail your designer has specified.
  2. Openings are measured and grouped by detail.
  3. Improvised fillers and failed sealant are removed.
  4. Mineral wool or other backing is fitted where required.
  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.

Before we start on site

  • Tell staff and tenants when we will be in
  • Send asbestos survey details if the building is pre-2000
  • Make sure the joints can be reached

Advice

Common problems we fix in Billericay

Openings in fire-resisting walls usually appear when services are added or changed. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser leaves an opening that nobody returns to. Over a few years of fit-outs, a wall can collect a lot of these.

Things that usually lead to an enquiry:

  • Non-fire-rated filler around services
  • Open linear gaps along the top of fire-resisting walls
  • Openings left by services added after handover
  • Fire-rated sealant that has cracked or shrunk back

Holiday works at schools like Sunnymede Junior School often leave service openings to seal before pupils return.

What your quote should include

  • Whether old or failed sealant will be cut out, not overlaid
  • Their public liability cover
  • Which product they’ll use, and why it suits the joint
  • Will CSCS-carded applicators be on site?

Our contractor checklist

Should maintenance staff do it?

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Why deal with it now?

It is cheaper to seal service penetrations as each services package finishes than to come back for them later. Openings are visible, access is open and nothing has to be taken down and each detail can be checked as we go. In a town such as Billericay, a lot of buildings are older and have been altered over time, and joints where old meets new tend to fail first. Resealing them early protects the building behind.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.

Why us?

  • Specification-led, product-correct work
  • Fully insured, including public liability cover
  • Constructionline member for supplier checks
  • CHAS accredited

Keeping the joints sound

Regular inspection catches problems early. In particular:

  • Treat an open penetration as a priority repair
  • Foam or ordinary sealant is never a fire-seal repair
  • Ask the designer to confirm details early on refits
  • Look above ceilings when tiles are lifted for other jobs

Allow the manufacturer’s stated cure time before boxing in or decorating. Some fire-rated sealants accept paint and some don’t, so check the product data first.

Specify fire stopping early on refits, not as an afterthought. Details can then be picked to suit the actual pipes, cables and ducts, and the work runs in step with the M&E.
