Fire stopping for commercial buildings in Burntcommon

The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints and the results are classified to BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. If you’re dealing with unsealed openings around new pipes and cables and unsealed joints where partitions meet the slab, we can put it right. Facilities teams, main contractors and managing agents in Burntcommon tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Rural conversions around Burntcommon can put new fire-resisting partitions inside older structures. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What sealant work can’t fix

Honesty saves time and money. New sealant won’t cure:

  • Approving the work on behalf of building control
  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Gaps in walls that were never built as compartment walls

Not sure which it is? You can speak to us on 01277 525 020 or send photos by email and we’ll tell you honestly.

Surfaces we seal

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

Compartments and services around Burntcommon

For England, the fire stopping of penetrations is dealt with in Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail. Central London is about 23 miles from Burntcommon. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls; the gaps need the specified seal.

Workshops and IT rooms at colleges like Woking College, 2.2 miles north-west of Burntcommon, are re-serviced often, leaving penetrations to seal. Residences at universities like University of Surrey - Stag Hill Campus (4.5 miles south-west of Burntcommon) have compartment walls that must be resealed whenever services change.

Burntcommon: questions and answers

Can you take on a job at a hospital such as Woking Community Hospital?

Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is Burntcommon too far out for you?

Not at all. Burntcommon is within our area. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

What does an EI 60 rating mean?

BS EN 1366-3 covers penetration seals and BS EN 1366-4 covers linear joints. Classification follows BS EN 13501-2 as E for integrity and I for insulation, with a time such as EI 60 or EI 120. The rating applies to the product as tested.

How long before the joints can be used?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.

Can you handle several sites?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

Can you work to our specification?

Yes. Send it with your enquiry, and the quote will be based on it.

Are you members of a third-party fire-stopping installer scheme?

No. We are not members of a third-party fire-stopping installer scheme. Our credentials are CHAS accreditation, Constructionline membership and CSCS-carded applicators, and we are fully insured. If your contract requires third-party installer certification, we’re not the right fit for that package.

Keeping the joints sound

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

  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Ask which product is in place before decorating
  • Get seals inspected before ceilings and boxing close
  • Ask the designer to confirm details early on refits

New services after handover are a common way fire stopping gets breached. Building it into each contractor’s sign-off keeps the walls intact.

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.

Do you need fire stopping in Burntcommon?

Most open service penetrations are left by later work. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser can leave the hole behind. Over a few years of fit-outs, a wall can collect a lot of these.

Clients typically get in touch after noticing one or more of the following:

  • Openings left by services added after handover
  • Head-of-wall gaps with no fire seal
  • Expanding foam used as fire stopping
  • Fire-stopping items raised at inspection or handover

Tenant changes at parks like Merrow Business Park, 2.1 miles south-west of Burntcommon, bring new data and services, and openings through fire-resisting walls need the specified seal.

What your quote should include

  • Their approach to joint depth and backing
  • Will CSCS-carded applicators be on site?
  • What level of public liability insurance do they hold?
  • Which product they’ll use, and why it suits the joint

Questions to ask before you appoint anyone

On site: what to expect

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. If others near Burntcommon need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  1. We start with your penetration schedule, drawings or specification.
  2. Access, permits and the order of areas are agreed with the site team.
  3. We compare every service penetration with its tested detail before sealing.
  4. Unsuitable material is removed and the opening cleaned.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. We tell you about openings that need a different product.

What we need from you

  • Send asbestos survey details if the building is pre-2000
  • Tell staff and tenants when we will be in
  • Clear stock, furniture or equipment away from the joints

Advice

Doing it in-house

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

What affects the price in Burntcommon

There’s no standard rate for sealant work, since sites vary so much. What we look at:

  • Specialist products, such as fire-rated or hygienic sealants
  • The site’s rules and procedures
  • Distance, for remote addresses
  • Working within restricted access windows

What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote when you are ready.

What to include in your enquiry

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

  • Rough lengths or quantities, or drawings if you have them
  • Access details, including height
  • The site address and postcode
  • Your programme or deadline

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.
