About our fire stopping in East Challow

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. A rating such as EI 60 only holds when the product is installed as it was tested. So our job is to reproduce that arrangement faithfully. We work on pipe penetrations, small duct penetrations where the tested detail allows and joints between fire-resisting walls and floors, and what we’re called in for most is old intumescent sealant that has split away and expanding foam used as fire stopping. A specialist sealant contractor works differently from a general builder: on jobs in East Challow, preparation and product choice get the time they need.

Barn and farm-building conversions near places like East Challow often combine new partitions with old walls. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

From enquiry to sign-off

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact. For work around East Challow, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. We ask for the product and detail your designer has specified.
  2. We sort the openings by the detail each one needs.
  3. Improvised fillers and failed sealant are removed.
  4. Mineral wool or other backing is fitted where required.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Getting the site ready

  • Send your site hours and access windows
  • Have the specification and drawings to hand
  • Move anything stored against the joints

For managing agents and facilities managers

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. East Challow can form part of a wider programme.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

What sets the cost

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

  • Travel to remote or island sites
  • The site’s rules and procedures
  • Specialist products, such as fire-rated or hygienic sealants
  • Removal of failed or old sealant

The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote when you are ready.

Before you send an enquiry

However big the job, these details speed things up:

  • The postcode of the building
  • Whether an asbestos survey exists
  • How the joints are reached, and at what height
  • Photos of the joints, close up and from further back

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, give us a call on 01277 525 020 or email a schedule or drawings.

Your questions answered

Can you work on a hospital site such as Wantage Community Hospital?

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is East Challow too small for you to travel to?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.

Is the work guaranteed?

Yes. Our workmanship is backed for 12 months on every job.

Can you quote from photos?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.

Can weather delay the job?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Can you work to our specification?

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

Is the BS 476 change in 2029 relevant to fire stopping?

From 2 September 2029, Approved Document B in England drops its references to BS 476 classes, with transitional arrangements set by the Government. After that, the European classification under BS EN 13501-2 is the route. Your designer will choose products with the right evidence.

Site staff or a sealant specialist?

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

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.

Keeping the joints sound

For the best life from the joints:

  • Report damaged or disturbed seals as soon as they’re spotted
  • Record which product was used where
  • Foam or ordinary sealant is never a fire-seal repair
  • Ask the designer to confirm details early on refits

Keep the product data and installation details with the building’s fire safety information. It makes later repairs much easier to match.

Specify fire stopping early on refits, not as an afterthought. Details can then be picked to suit the actual pipes, cables and ducts, and installation follows the programme.

Service penetrations in East Challow buildings

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. What we install is set by the specification, and it goes in to the tested detail. East Challow is about 59 miles from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.

For a unit at a centre such as Grovelands Shopping Centre, 1.5 miles to the north-east of East Challow, penetration seals are worth checking after each shop fit. For a unit at a site such as W&G Industrial Estate, 0.7 miles north-west of East Challow, new power or data runs between office and warehouse can breach a compartment wall.

What we’re called out for in East Challow

Mixing products or improvising a detail breaks the link with the test evidence. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are the usual culprits.

What tends to prompt an enquiry:

  • Service penetrations left open after M&E works
  • Unsealed joints where partitions meet the slab
  • Fire stopping installed outside its tested range
  • Fire-rated sealant that has cracked or shrunk back

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

What your quote should include

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Is the sealant right for the movement and the substrate?
  • How they handle RAMS and site documents
  • Will CSCS-carded applicators be on site?
