Fire stopping for Turnpike Lane sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

From enquiry to sign-off

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. For a job in Turnpike Lane, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.

  1. We ask for the product and detail your designer has specified.
  2. Openings are measured and grouped by detail.
  3. Old or wrong materials are cut out.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. Completed areas are checked with you, with the records agreed when we quoted.

What we need from you

  • Point out parking and an unloading spot
  • Make sure the joints can be reached
  • Let building users know which areas are affected

Getting a fixed quote

A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or ring 01277 525 020 or email us if you’d rather talk the job through.

Fire stopping for commercial buildings in Turnpike Lane

Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. We work to the product’s tested detail for every seal rather than guesswork. Most enquiries involve expanding foam used as fire stopping and openings left by services added after handover, on service gaps in risers, pipe penetrations and small duct penetrations where the tested detail allows. Facilities teams, main contractors and managing agents in Turnpike Lane tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Taller residential buildings in London may fall under the Building Safety Act’s higher-risk regime, where fire-stopping records get close attention. Our part is installing the specified fire-rated sealant; tell us what records you need and we will confirm with the quote.

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.

How the quote is worked out

Your fixed quote is built from the real scope. It takes account of:

  • Distance, for remote addresses
  • Backing rod, priming and other preparation
  • Working within restricted access windows
  • How much there is to seal

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

What we need to price the job

We can often quote from photographs and a few details. Please tell us:

  • A wide shot and a close-up of the area
  • The asbestos register, for older buildings
  • Any specification or named product
  • Your programme or deadline

Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to speak to us on 01277 525 020 or email the details over.

Penetration seals near Turnpike Lane

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. Either way, we install the specified product to its tested detail. Turnpike Lane has a good number of hotels close by, all within 2 miles. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.

Workshops and IT rooms at colleges like The College of Haringey, 1.4 miles to the east of Turnpike Lane, are re-serviced often, leaving penetrations to seal. Large healthcare estates like St Ann's Hospital (to the south-east of Turnpike Lane) change their services often, so penetration seals are worth checking after M&E work. At a retail site such as Arena Shopping Park, 1 mile to the south-east of Turnpike Lane, walls between units may be fire-resisting, so services added in a refit need the specified seal.

Turnpike Lane is about 3 miles north of Highbury, in Greater London. We cover commercial sites throughout Turnpike Lane, for single jobs and planned programmes alike. Across Greater London, 764 places are covered, including Turnpike Lane. Our London page has more on work in that area.

What the job involves on each surface

Metal pipes

Copper and steel pipes are a common service penetration for fire-rated sealant. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on.

Masonry and concrete

Many seals are made in blockwork, brickwork or concrete slabs. Dust and debris are cleared from the opening, with backing added if the detail requires it.

What we can’t put right

Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:

  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Approving the work on behalf of building control
  • Plastic pipes whose detail calls for a collar or wrap

If you are not sure, just call 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.

Joints and surfaces we work on

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

Your questions answered

How does the move away from BS 476 affect penetration seals in Turnpike Lane?

References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is 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 your area include sites such as Arena Shopping Park, near Turnpike Lane?

Yes, sites like Arena Shopping Park are within our area, along with the rest of Turnpike Lane. Photos and a short description are enough for a first look.

Which sealant will you use?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Will your applicators have CSCS cards?

Yes. We use CSCS-carded applicators, which many sites require.

How do I request a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.

Can you fit around our working hours?

The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.

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’ll confirm the curing time on the day.

Doing it in-house

Using site staff can make sense for a small touch-up, but larger jobs are different: 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: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Keeping the joints sound

To get the most from the new sealant:

  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Check with the data sheet before painting over fire sealant
  • Record which product was used where
  • Flag new cables with no seal around them

Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Watch for cracked sealant, new services with no seal and openings that have grown, and report them promptly.

Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job compared with dozens found at once.
