Fire stopping near Barkingside

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Should maintenance staff do it?

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Fire stopping in Barkingside, done properly

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. Most enquiries involve fire-stopping items raised at inspection or handover and openings left by services added after handover, on linear gaps at wall heads, service gaps in risers and joints between fire-resisting walls and floors. Whoever orders the work in Barkingside, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Taller residential buildings in London may fall under the Building Safety Act’s higher-risk regime, where fire-stopping records get close attention. We install what the designer or fire engineer has specified, and if you need records of the work, tell us and we’ll confirm with the quote.

We stand by our work: 12 months, guaranteed. That covers our preparation and application.

When it isn’t the sealant

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Construction that lacks the fire resistance the seal relies on
  • Fire risk assessments, a job for a competent assessor
  • Plastic pipes whose detail calls for a collar or wrap

If in doubt, call 01277 525 020 or email the details over and we will say what we think before you book.

Joints and surfaces we work on

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

Common problems we fix in Barkingside

Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is how unsuitable products and improvised details end up in compartment walls.

These are often picked up first by site or facilities staff:

  • Old intumescent sealant that has split away
  • Fire stopping installed outside its tested range
  • Service penetrations left open after M&E works
  • Unsealed joints where partitions meet the slab

Workshops and IT rooms at colleges like New City College, 0.6 miles south-west of Barkingside, are re-serviced often, leaving penetrations to seal.

Questions to ask before you book

  • Will CSCS-carded applicators be on site?
  • Their plan for phasing and protecting the area
  • Health and safety accreditation such as CHAS
  • Do they follow the manufacturer’s priming guidance?

Questions to ask before you appoint anyone

Keeping the joints sound

A few simple habits keep the new joints working:

  • Report damaged or disturbed seals as soon as they’re spotted
  • Include service cupboards in routine inspections
  • Agree the fire-stopping specification before services go in
  • Arrange inspection before areas are covered up

Store the specified product details somewhere the next contractor can find them. It makes later repairs much easier to match.

Keep a register of where seals are and what they are made of. When a new service goes through, everyone knows which product and detail to match, which saves guesswork.

Questions about Barkingside

Do you work in occupied care homes around Barkingside?

Yes. We agree rooms and times with the manager and work a few areas at a time. Tell us about any infection-control or safeguarding requirements and we will work to them.

Is hospital work, at somewhere like King George Hospital, something you do?

Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.

How long do sealant joints last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.

Can the sealant be colour-matched?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

How do we ask for a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.

Will you quote for a small job?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

From enquiry to sign-off

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. In Barkingside, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.

  1. First we confirm the product and tested details named in the specification.
  2. Openings are measured and grouped by detail.
  3. Improvised fillers and failed sealant are removed.
  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.

Before we start on site

  • Tell staff and tenants when we will be in
  • Clear stock, furniture or equipment away from the joints
  • Share your working hours and any access restrictions

Request a quote

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photos and a few notes.

Surface by surface

Linear joints

Head-of-wall gaps, slab edges and wall junctions are linear joints. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed and the installation has to fit inside those limits.

Risers and ceiling voids

Risers and ceiling voids hold most of a building’s service penetrations. Access is often tight, so we agree it with you in advance, including keys, permits and any isolations.

Where services cross fire walls in Barkingside

Fire stopping of openings and penetrations in England falls under Approved Document B. 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. Our part stays the same: the specified product, installed to its tested detail. There are plenty of hotels within about 2 miles of Barkingside. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail.

For an estates team at a campus like University of Portsmouth Walthamstow Campus, 4.4 miles to the west of Barkingside, summer M&E works are usually followed by a round of penetration sealing. At a retail site such as Newbury Retail Park (0.8 miles south of Barkingside), walls between units may be fire-resisting, so services added in a refit need the specified seal.
