About our fire stopping in South Stifford

It helps to set out our role at the start. The designer, fire engineer or building control decides which fire stopping is required; sign-off sits with them too. What we bring is careful installation of the specified sealant, to the maker’s guidance on buildings around South Stifford. We work on service gaps in risers, pipe penetrations and joints between fire-resisting walls and floors, and what we’re called in for most is service penetrations left open after M&E works and unsealed penetrations discovered above suspended ceilings. One point of contact handles commercial sealant work in South Stifford from the first photographs to the final walk-round, whether it’s one building or several.

Buildings in a smaller place such as South Stifford that need fire-rated sealing are typically schools, care homes, surgeries, small offices and flats over shops. Specified fire-rated sealant goes around new services there, built to match the manufacturer’s detail.

Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

Honest limits

Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:

  • Fire risk assessments, a job for a competent assessor
  • Plastic pipes whose detail calls for a collar or wrap
  • Deciding what a wall or floor needs, which belongs to the designer

If you are not sure, just call 01277 525 020 or send photos by email and we will give you a straight answer before you book.

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
  • Pipe penetrations
  • Service gaps in risers

Building owners, agents and FMs in South Stifford

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. Keys, access and contacts can be agreed in advance.

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Different surfaces, different methods

Linear joints

Head-of-wall joints often have to absorb slab deflection. We use the product and backing the detail names for that movement.

Risers and ceiling voids

Voids hide a lot of unsealed openings. We follow your schedule area by area and tell you about openings outside the list.

Signs you need fire stopping in South Stifford

Head-of-wall joints and wall-to-wall junctions are frequent weak points. Movement in the frame or slab can open the joint. Linear joint details set a width range and movement capability, and the seal has to sit within them.

If one of these sounds familiar, it’s time for a closer look:

  • Damaged fire seals in risers and voids
  • Service penetrations left open after M&E works
  • Fire sealant pulled out of the opening
  • Seals that don’t match their tested detail

Hotels like Ibis Hotel, 1.3 miles west of South Stifford, are refurbished in phases, and each phase can open up compartment walls.

What your quote should include

  • How they handle RAMS and site documents
  • How the existing material will be dealt with
  • Their plan for phasing and protecting the area
  • How the joint faces will be prepared and primed

How to choose a sealant contractor

Why act early in South Stifford

Open penetrations multiply: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Why us?

  • A fixed quote before work starts
  • Sealing commercial buildings since 2005
  • Our applicators hold CSCS cards
  • Constructionline member

Fire stopping around South Stifford: points for this area

In England, Approved Document B covers fire stopping of openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. There are several hotels within about 2 miles of South Stifford. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.

For an estates team at a campus like University of Greenwich, 3.2 miles to the south of South Stifford, summer M&E works are usually followed by a round of penetration sealing. Large healthcare estates like Thurrock Community Hospital, 2 miles to the north-east of South Stifford, change their services often, so penetration seals are worth checking after M&E work.

On site: what to expect

The first thing on site is a walk round with your contact, 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. Several jobs near South Stifford can be grouped on one trip. Mention the building’s opening times and we will work within them.

  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. Old or wrong materials are cut out.
  4. Mineral wool or other backing is fitted where required.
  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.

Preparing the site

  • Flag any permit to work we’ll need
  • Let building users know which areas are affected
  • Make sure the joints can be reached

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

Can you fire stop behind the services contractors?

Is fire stopping in Scotland covered by different guidance?

Scotland sets its own building regulations, with Technical Handbooks, and England uses Approved Document B. Either way, we install the specified sealant to its tested detail.

Can one quote cover more than one building?

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

How much does the work cost?

That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we will price it properly.

Can you tell us what fire stopping our building needs?

No, that isn’t our role. Once you have a specification, we can price and install the sealant elements of it and point out anything needing another product.
