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

How we handle fire stopping in Cutlers Green

The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints. A rating such as EI 60 only holds when the product is installed as it was tested. Reproducing the tested arrangement on site is the part we take care of. We work on small duct penetrations where the tested detail allows, service gaps in risers and pipe penetrations, and the failures we’re asked to look at most are expanding foam used as fire stopping and unsealed openings around new pipes and cables. Most enquiries from Cutlers Green start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

For a smaller site near Cutlers Green, 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.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Quoting for work in Cutlers Green

What shapes the price:

  • How accessible the joints are
  • Location, for remote and island sites
  • The site’s rules and procedures
  • The product specified

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.

Details that help us quote

We can often quote from photographs and a few details. It helps to include:

  • Any dates the work must fit around
  • The site address and postcode
  • Any specification or named product
  • Anything awkward about access or site hours

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to speak to us on 01277 525 020 or email the details over.

From enquiry to sign-off

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Rural sites near Cutlers Green may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  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. We walk the completed areas with you and confirm the records agreed at quote stage.

Getting the site ready

  • Let building users know which areas are affected
  • Have the specification and drawings to hand
  • Make sure the joints can be reached

Site staff or a sealant specialist?

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Aftercare for building managers

Keep the joints in good shape with a few simple steps:

  • Agree the fire-stopping specification before services go in
  • Leave fire sealant to cure fully before covering it
  • Have penetrations checked while they can still be seen
  • Look above ceilings when tiles are lifted for other jobs

After the work, brief anyone else working in the area that the openings are now sealed. Any seal cut back for a new service needs reinstating to its tested detail, by someone who knows the system.

On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned, and the work runs in step with the M&E.

Fire stopping in Cutlers Green: the local picture

For England, the fire stopping of penetrations is dealt with in Approved Document B. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. Our part stays the same: the specified product, installed to its tested detail. Cutlers Green is about 36 miles from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.

For a hotel such as Swan Hotel (0.9 miles east of Cutlers Green), penetration seals are worth checking after any refit or services upgrade. Wherever services are added at a hospital such as Saffron Walden Community Hospital (5.6 miles north-west of Cutlers Green) the compartment line has to be made good with the specified product. Schools such as Thaxted Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.

Cutlers Green is about 6 miles south-east of Saffron Walden, in Essex. Looking for fire stopping in Cutlers Green? We can help, as we do across Essex. Cutlers Green is one of 644 places we cover in Essex for service penetrations. Sites around London have their own page, about 36 miles away.

What the job involves on each surface

Small ducts

We seal around ducts only within what the tested detail covers. The ductwork, its supports and any dampers are for the ductwork contractor.

Plastic pipes

Plastic waste pipes through slabs come up often. The detail decides whether sealant alone is enough, and we’ll never swap a specified collar for sealant.

FAQs: Cutlers Green

Is Cutlers Green off your patch?

No. Places such as Cutlers Green are covered as much as the big towns. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.

Would you work within a site like Saffron Walden Community Hospital?

Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.

Can you reseal penetrations after our M&E works?

Yes, provided a specification covers them. Openings left by new services are among the most common jobs we see.

Will you write the fire-stopping specification?

No. The specification comes from your designer, fire engineer or building control. Our role is fitting the specified fire-rated sealant, following the maker’s tested details.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

Is fire stopping in Scotland covered by different guidance?

Building standards in Scotland are separate from England’s, and England uses Approved Document B. Either way, we install the specified sealant to its tested detail.

How do we ask for a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.

What we can’t put right

Being straight saves everyone time. New sealant won’t cure:

  • Construction that lacks the fire resistance the seal relies on
  • Issuing fire ratings or certificates for seals
  • Deciding what a wall or floor needs, which belongs to the designer

Not sure which it is? You can call 01277 525 020 or send photos by email and we will tell you honestly before you book.
