Fire stopping near Ivy Chimneys

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Fire stopping for commercial buildings in Ivy Chimneys

Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We don’t hold a third-party fire-stopping installer certificate, and we won’t pretend otherwise. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. We work on linear gaps at wall heads, cable penetrations and joints between fire-resisting walls and floors, and what we are called in for most is improvised or mixed-product fire seals and builders’ foam or ordinary silicone in compartment walls. Whoever orders the work in Ivy Chimneys, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

For a smaller site near Ivy Chimneys, we plan to do all the penetrations in one go, with the specification and photographs sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

A 12-month guarantee applies to all our work in Essex. Should something we installed fail, call 01277 525 020 or email a schedule or drawings and we will come back to it.

Leave it or put it right?

Fire stopping is a regular point raised at inspections and handover. Finding unsealed or improvised openings late can hold up a programme which is why earlier is better. Converted and older buildings near places like Ivy Chimneys tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

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’ll put a fixed figure on it.

What you get with us

  • 12 months’ guarantee on every job
  • Old sealant cut out, never sealed over
  • CHAS accredited
  • Constructionline member for supplier checks

On site: what to expect

Tell us your site hours and access windows and we will plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. Jobs in and around smaller places like Ivy Chimneys are typically planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. Mineral wool or other backing goes in wherever the detail asks.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Preparing the site

  • Point out any areas we must not close
  • Warn occupants and staff about the work
  • Clear stock, furniture or equipment away from the joints

What sets the cost

Each job is priced on its own details. The things that drive the figure:

  • The total length or number of joints
  • Site requirements such as inductions and permits
  • How much existing material needs removing
  • Location, for remote and island sites

The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

Sending details for a quote

The more we know, the firmer the quote. When you get in touch, include:

  • The site address and postcode
  • Your programme or deadline
  • Access details, including height
  • The product your specification calls for

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Building owners, agents and FMs in Ivy Chimneys

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

CHAS accredited and a Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.

Aftercare for building managers

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

  • Look above ceilings when tiles are lifted for other jobs
  • Arrange inspection before areas are covered up
  • Ask the designer to confirm details early on refits
  • Leave fire sealant to cure fully before covering it

After the work, brief anyone else working in the area that the openings are now sealed. If a seal has to be opened for a new service, it should be reinstated to the same detail using the same product.

Ask every contractor who works in risers or voids to report openings they create. Small habits like this stop openings building up.

Compartments and services around Ivy Chimneys

Ivy Chimneys is about 16 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls. Ivy Chimneys has several hotels close by, all within 2 miles. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail.

In a building such as Church of St John the Baptist, any service penetration through a fire-resisting wall should be sealed to the specified detail. On a site such as Hobbs Cross Business Centre, which lies south-east of Ivy Chimneys, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product.

Ivy Chimneys is about 1 mile south-west of Epping, in Essex. We cover commercial sites throughout Ivy Chimneys. Our Essex coverage takes in 644 places. For work in that direction, see our London page (16 miles or so).

Signs you need fire stopping in Ivy Chimneys

Physical damage is another reason seals stop doing their job. Maintenance work can knock a seal, cut it back for an extra cable or remove it with an old pipe.

These are often picked up first by site or facilities staff:

  • Open linear gaps along the top of fire-resisting walls
  • Fire stopping installed outside its tested range
  • Fire-stopping items raised at inspection or handover
  • Builders’ foam or ordinary silicone in compartment walls

Schools such as Ivy Chimneys Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.

Questions to ask before you book

  • How they handle RAMS and site documents
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • The named product and why it was chosen
  • Will failed sealant be removed rather than covered?
