Fire stopping for Newhall sites

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

How we handle fire stopping in Newhall

Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. We work to the product’s tested detail for every seal rather than guesswork. If you have unsealed joints where partitions meet the slab and openings found when ceilings come down for a refit, we can put it right, on linear gaps at wall heads, service gaps in risers and pipe penetrations alike. Facilities teams, main contractors and managing agents in Newhall tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Around Newhall, penetration and linear seals tend to be one-building jobs. Send the specification, drawings or photos of the openings and we’ll quote to suit.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Compartment walls and floors in Newhall

Harlow, one of the planned towns of the twentieth century, takes in or adjoins Newhall. Older buildings in planned towns have often been re-serviced several times, so penetrations left behind should be sealed with the specified product. Newhall lies roughly 21 miles out from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.

Shop fits in centres such as Dukes Retail Park, 1.3 miles to the north-west of Newhall, can bring new services through fire-resisting walls between units, which then need the specified seal. Workshops and IT rooms at colleges like Harlow College, 1.5 miles to the west of Newhall, are re-serviced often, leaving penetrations to seal. Office fit-outs on sites such as Harlow Innovation Park (less than half a mile north-west of Newhall) add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it.

Newhall is about 1 mile east of Harlow, in Essex. Looking for fire stopping in Newhall? We can help, as we do across Essex. 644 places across Essex fall within our area, including Newhall. Sites around London have their own page, about 21 miles away.

Why act early in Newhall

Sealing behind the M&E trades area by area beats a sweep at the end. While the area is still open, every opening is easy to see and reach and each detail can be checked as we go. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Newhall: questions and answers

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

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. Our part doesn’t change: the specified product, to its tested detail.

Do you seal service penetrations in hotels around Newhall?

Yes, where the specification calls for fire-rated sealant. We match the product to the wall or floor and the services, and say if something other than sealant is needed.

How do we ask for a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.

Do you have public liability insurance?

Yes. Our insurance certificate can be sent alongside the quote.

When can you be on site?

Give us your site hours and any access windows in your enquiry, and we will plan around them. You can reach the office between 8am and 5pm, Monday to Friday.

Are you CHAS accredited and on Constructionline?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Do you take on small jobs?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

Keeping the joints sound

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Settle who seals which penetrations at the start of a project
  • Include service cupboards in routine inspections
  • Foam or ordinary sealant is never a fire-seal repair

Once the seals are in, tell other trades they exist and must not be disturbed. Any seal cut back for a new service needs reinstating to its tested detail using the same product.

Ask every contractor who works in risers or voids to report openings they create. It costs little and catches breaches early.

Diagnose, treat, 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. Work in places the size of Newhall is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.

  1. The specification and schedule come first, so we know which details apply.
  2. We plan the sequence of floors, risers and voids with you.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Foam, ordinary sealant and debris come out first.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. We tell you about openings that need a different product.

Before we start on site

  • Flag any permit to work we will need
  • Arrange parking or a loading space
  • Send any specification or drawings in advance

Ask for a quote

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call 01277 525 020 or email the details over.

When it isn’t the sealant

We check first that sealant really is the fix. It isn’t the answer for:

  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Construction that lacks the fire resistance the seal relies on
  • Fire doors, dampers or other fire safety equipment

If in doubt, speak to us on 01277 525 020 or email drawings and photos and we will say what we think.

Surfaces we seal

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

Quoting for work in Newhall

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

  • Site requirements such as inductions and permits
  • The size and state of each joint
  • Location, for remote and island sites
  • Any access equipment needed

Pricing service penetrations depends on how many there are, their condition and the access. Call for a quote.

Sending details for a quote

Good information means a firmer quote. Helpful details to send:

  • The product your specification calls for
  • Where the site is, with the postcode
  • How the joints are reached, and at what height
  • Drawings or a marked-up plan, if available

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

Surface by surface

Plastic pipes

In a fire, plastic pipework melts away and leaves an opening. Small sizes are sometimes covered by an intumescent sealant detail, though larger ones typically call for a collar or wrap. We check the pipe material and diameter against the detail before we start.

Small ducts

Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Larger or fire-rated ductwork usually needs a different solution set by the designer and we flag that rather than guess.
