Fire stopping near Audley End

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Fire stopping for commercial buildings in Audley End

For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. We work from your penetration schedule or marked-up drawings alongside the manufacturer’s details. Tell us what records you need and we’ll confirm with the quote. If you have service penetrations left open after M&E works and improvised or mixed-product fire seals, we can help. Whoever orders the work in Audley End, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

For a smaller site near Audley End, we plan to do all the penetrations in one go, with the specification and photographs sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Do you need fire stopping in Audley End?

When a seal departs from its tested detail, the evidence no longer covers it. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are the usual culprits.

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

  • Penetration schedules that need working through
  • Service penetrations left open after M&E works
  • Unsealed joints where partitions meet the slab
  • Expanding foam used as fire stopping

Hotels such as The Saffron Hotel (to the north-east of Audley End) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.

Before you book anyone

  • Is the sealant right for the movement and the substrate?
  • Do they follow the manufacturer’s priming guidance?
  • How the existing material will be dealt with
  • The terms of the workmanship guarantee

Questions to ask before you appoint anyone

Our process

Before we leave any area, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. Jobs in and around smaller places like Audley End are usually planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. We read the specification, drawings or penetration schedule you send.
  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. 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

  • Point out any areas we must not close
  • Tell us your opening times and when work is allowed
  • Flag any permit to work we will need

After the work

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

  • Check with the data sheet before painting over fire sealant
  • Record which product was used where
  • Check risers and ceiling voids after each round of works
  • Have penetrations checked while they can still be seen

Store the specified product details somewhere the next contractor can find them. Anyone resealing later needs to know which product and detail were used.

On fit-outs, get the fire-stopping specification agreed before the services go in. Details can then be picked to suit the actual pipes, cables and ducts, and installation follows the programme.

Why act early in Audley End

A seal that doesn’t match its tested detail gives false comfort. Correcting it means cutting it out and starting again with the specified product, so it makes sense to get it right first time. Halls, stores and units around places like Audley End may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Why us?

  • Fully insured
  • Clear, fixed quotes
  • Old sealant cut out, never sealed over
  • Health and safety: CHAS accredited

Compartment walls and floors in Audley End

Fire stopping of openings and penetrations in England falls under 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. Audley End lies roughly 38 miles out from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.

Office fit-outs on sites such as Bearwalden Business Park (to the south-west of Audley End) add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it. Wherever services are added at a hospital such as Saffron Walden Community Hospital (no A&E) (to the east of Audley End) the compartment line has to be made good with the specified product.

Different surfaces, different methods

Cables and cable bundles

Data cabling added after handover is a regular cause of open service penetrations. We reseal around them to the specified detail, and we tell you if the bundle exceeds what sealant covers.

Linear joints

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

Your questions answered

How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Audley End?

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.

Do you work on fire-rated sealing in hotels in Audley End?

Yes, to the specification and the product’s tested detail. Each seal follows the tested detail, and rooms are done in turn.

How long will the new sealant last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

How do I request a quote?

You can use the quote form on this site; alternatively, give us a call on 01277 525 020 or use the quote form. Photos, drawings or a joint schedule help us quote quickly.

Can you fit around our working hours?

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.

How many days will you need on site?

We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

How the quote is worked out

Your fixed quote is built from the real scope. It takes account of:

  • Backing rod, priming and other preparation
  • Which sealant the job calls for
  • Distance, for remote addresses
  • Site requirements such as inductions and permits

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 and we’ll price your job on its own details.

What to include in your enquiry

There’s no need for a formal survey. A few details are enough to get going:

  • When you need the work done
  • The site address and postcode
  • The asbestos register, for older buildings
  • Access details, including height

For a fixed quote, phone 01277 525 020 or email the details over, telling us the site location and the nature of the job. Our quote form is another easy route.
