How we handle fire stopping in Hackney Wick

For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. We work from your penetration schedule or marked-up drawings and the specified product data. Tell us what records you need and we’ll confirm with the quote. Most enquiries involve fire seals cut back for extra cables and never reinstated and hidden openings found during inspections, across linear gaps at wall heads, service gaps in risers and pipe penetrations. A specialist sealant contractor works differently from a general builder: on jobs in Hackney Wick, preparation and product choice get the time they need.

In a London area such as Hackney Wick, buildings are refitted often, and every new cable, pipe or duct through a fire-resisting wall or floor leaves a gap. Where the specification names fire-rated sealant, it goes in exactly as the manufacturer’s test evidence shows for that wall or floor.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

What affects the price in Hackney Wick

A fixed quote reflects the actual work. It takes account of:

  • Removal of failed or old sealant
  • Site requirements such as inductions and permits
  • Any access equipment needed
  • Travel to remote or island sites

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.

Details that help us quote

However big the job, these details speed things up:

  • What the building is and how it’s used
  • When you need the work done
  • Rough lengths or quantities, or drawings if you have them
  • How the joints are reached, and at what height

The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or phone 01277 525 020 or send details through our quote form to discuss it first.

Diagnose, treat, sign off

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.

  1. We read the specification, drawings or penetration schedule you send.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. We fit the backing the detail asks for, to the stated depth.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

What we need from you

  • Tell us which areas need to stay in use
  • Move anything stored against the joints
  • Share your working hours and any access restrictions

Surface by surface

Masonry and concrete

Many seals are made in blockwork, brickwork or concrete slabs. Dust and debris are cleared from the opening, so the sealant and any backing sit properly.

Linear joints

Joints at the top of partitions may need to move as the slab above deflects. We use the product and backing the detail names for that movement.

Leave it or put it right?

Open penetrations multiply: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable and avoids a much larger catch-up later. In Hackney Wick, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

Fire stopping in Hackney Wick: the local picture

London’s office and residential buildings are refitted constantly, and each round of cabling or pipework can leave open penetrations. We install fire-rated sealant where it is specified and work within the building manager’s permit system. There are 25 care or nursing homes within about 2 miles of Hackney Wick. In a care home, any new pipe or cable through a fire-resisting wall should be sealed to the specified detail. We install fire-rated sealant to the tested detail where it is specified.

Residences at universities like University of Staffordshire London Campus, under half a mile north of Hackney Wick, have compartment walls that must be resealed whenever services change. Industrial units on estates such as Hamlet Industrial Estate, less than half a mile north-east of Hackney Wick, often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal. Hospital estates such as Homerton University Hospital, 1.1 miles north-west of Hackney Wick, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.

Hackney Wick is about 1 mile west of Stratford, in Greater London. Anywhere in E3, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Across Greater London, 764 places are covered, Hackney Wick among them.

Should maintenance staff do it?

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Hackney Wick: questions and answers

Do you cover business parks and estates near Hackney Wick, such as Hamlet Industrial Estate?

Yes. We cover Hackney Wick and the area around it, including industrial estates, business parks and retail parks such as Hamlet Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.

What happens to BS 476 references for fire stopping in Hackney Wick?

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

Does weather matter for sealant work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Do you need to see the site first?

It depends on the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.

Do you cover Hackney Wick?

Yes. Hackney Wick is in our area. For a quote, speak to us on 01277 525 020 or send details through our quote form.

Do you offer coloured sealant?

It depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

How long does a job like this take?

It depends on the scope, though a typical visit typically takes a single visit for a short list of penetrations, or a phased programme for a whole building. For bigger or phased jobs, we’ll set out a timescale with the quote.

Maintenance after handover

To get the most from the new sealant:

  • Check with the data sheet before painting over fire sealant
  • Check risers and ceiling voids after each round of works
  • Treat an open penetration as a priority repair
  • Get seals inspected before ceilings and boxing close

During planned inspections, look at seals in risers, cupboards and voids. Watch for cracked sealant, new services with no seal and openings that have grown.

Keep a register of where seals are and what they are made of. It tells the next contractor exactly what to reinstate, which saves guesswork.
