Need fire stopping in Bentley?

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

What we’re called out for in Bentley

Some seals fail because the wrong product went in: expanding foam or a general-purpose sealant pushed into a gap to tidy it. The opening looks sealed but has no fire test evidence behind it and has to be removed.

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

  • Head-of-wall gaps with no fire seal
  • Unsealed penetrations discovered above suspended ceilings
  • Unsealed openings around new pipes and cables
  • Fire-stopping items raised at inspection or handover

Older community buildings such as Church of St Paul that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Before you book anyone

  • Whether old or failed sealant will be cut out, not overlaid
  • Can the work be phased to keep areas open?
  • The named product and why it was chosen
  • The terms of the workmanship guarantee

Our contractor checklist

Fire stopping in Bentley

Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. Each seal follows the manufacturer’s tested detail rather than guesswork. We work on joints between fire-resisting walls and floors, cable penetrations and small duct penetrations where the tested detail allows, and the failures we are asked to look at most are unsealed joints where partitions meet the slab and openings found when ceilings come down for a refit. For commercial sealant work in Bentley, you deal with one contact from quote to sign-off, whether it’s one building or several.

A job near Bentley is normally planned around one visit, 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.

Every job we finish is backed by a 12-month workmanship guarantee, in Bentley as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Leave it or put it right?

Open service penetrations matter on ordinary days, not just in a fire: they also carry noise, draughts and smells between rooms. Sealing them to the specified detail deals with the fire risk first. Converted and older buildings near places like Bentley tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

What you get with us

  • Public liability insurance in place
  • Our applicators hold CSCS cards
  • Fixed quotes based on photographs, drawings or a visit
  • One contact handling all your sites

On site: what to expect

Tell us your site hours and access windows and we will plan around them. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. For a building around Bentley, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. First we confirm the product and tested details named in the specification.
  2. Openings are measured and grouped by detail.
  3. Old or wrong materials are cut out.
  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

  • Let building users know which areas are affected
  • For older buildings, check the asbestos register before work
  • Send any specification or drawings in advance

Quotes

Service penetrations in Bentley buildings

Central London is about 18 miles from Bentley. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment 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. What we install is set by the specification, and it goes in to the tested detail.

Holiday works at schools like Becket Keys Church of England School often leave service openings to seal before pupils return. Wherever services are added at a hospital such as Nuffield Hospital (2.7 miles south-east of Bentley) the compartment line has to be made good with the specified product.

Bentley is about 2 miles north-west of Brentwood, in Essex. Our applicators travel to Bentley for work on service penetrations. 644 places across Essex fall within our area, including Bentley. There’s a separate page for London, roughly 18 miles from Bentley.

Postcode districts covered here: CM14 and CM15. For a building on Mores Lane and Ashwells Road or nearby, send details and we will quote for service penetrations. Close to Bentley, our area also takes in Navestock Side (1 mile north-west), Coxtie Green (1 mile south), Doddinghurst Common (1 mile north-east), Horseman Side (1 mile west) and Crow Green (1 mile east). Further afield, our area takes in Chelmsford (11 miles north-east), Basildon (10 miles south-east), Harlow (11 miles north-west), Billericay (7 miles east), Rayleigh (15 miles east) and Loughton (8 miles west).

Local landmarks in Bentley

After the work

Once the work is signed off, a little attention goes a long way:

  • Flag new cables with no seal around them
  • Have penetrations checked while they can still be seen
  • Include service cupboards in routine inspections
  • Keep product data and details in the fire safety file

After every round of M&E works, check that the openings created have been sealed. A short check at the end of each job saves a long hunt later.

Looking at service areas on a regular cycle pays off. Catching a damaged seal early keeps the fix small; found late, it can be one of many.

Common questions from Bentley clients

Is Bentley off your patch?

Not at all. Bentley is within our area. London and every South East county are within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Can you work around term dates at a campus such as Havering Technical College?

Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Do you take on multi-site work?

Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.

Will you sign off the seals for us?

No. We don’t certify or sign off fire stopping, and we hold no third-party fire-stopping installer certificate. We work to the specification and the manufacturer’s installation guidance.

Do you need to see the site first?

That depends on the size and complexity of the job. Simple work can often be priced from photos, and bigger or more complex jobs usually get a visit.

How do I request a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.

Do you work in Scotland as well as England?

Our work covers Greater London, the South East and every Scottish council area. Scotland’s non-domestic Technical Handbook, clause 2.1.14, expects service penetrations to be fire stopped to at least the wall or floor’s fire resistance, with proprietary products tested for the end use.

Different surfaces, different methods

Drylining partitions

Holes in board are often cut larger than needed. An oversized hole may be outside the sealant’s range.

Masonry and concrete

Block walls and concrete floors are common substrates for penetration seals. Dust and debris are cleared from the opening.

Honest limits

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Plastic pipes whose detail calls for a collar or wrap
  • Signing off or certifying a building’s fire stopping
  • Writing the fire-stopping specification

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

Joints and surfaces we work on

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