Fire stopping for Puttock's End sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Fire stopping for commercial buildings in Puttock's End

Most of our fire stopping work happens after the building is up. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind. Those on your schedule are closed with the specified product. If you have snag lists that include open service penetrations and fire seals cut back for extra cables and never reinstated, we can help. Whoever orders the work in Puttock's End, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

For a smaller site near Puttock's End, we plan to do all the penetrations in one go, so send the specification and photographs first. Design and sign-off belong to the designer or building control; we install what’s specified.

We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Compartments and services around Puttock's End

A 2-mile radius around Puttock's End takes in a number of hotels. 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. Fire stopping of openings and penetrations in England falls under Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.

Large healthcare estates like Herts and Essex Hospital, 4.5 miles west of Puttock's End, change their services often, so penetration seals are worth checking after M&E work. Tenant changes at parks like Takeley Business Centre (0.9 miles north of Puttock's End) bring new data and services, and openings through fire-resisting walls need the specified seal.

Questions about Puttock's End

Do you cover business parks and estates near Puttock's End, such as Takeley Business Centre?

Yes, sites like Takeley Business Centre are within our area, along with the rest of Puttock's End. A few photos and the unit address let us price the work.

Can you take on a job at a hospital such as Herts and Essex Hospital?

Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.

Is the work guaranteed?

Yes. Workmanship is guaranteed for 12 months on every job.

How soon can the area be used again?

Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.

How much does the work cost?

It depends on the job: quantities, access, the product and any phasing. Call for a quote and we’ll price it properly.

Is colour matching possible?

That depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

Building owners, agents and FMs in Puttock's End

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so the building keeps working while we do.

Why deal with it now?

Inspections and handover checks often pick up fire stopping. Finding unsealed or improvised openings late can hold up a programme. Halls, stores and units around places like Puttock's End may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

There’s no price list, since every building and every scope is different. Call for a quote.

From enquiry to sign-off

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence, and our waste is bagged and taken away as we go. For work around Puttock's End, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  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. Anything outside the detail is reported to you rather than sealed.

Preparing the site

  • Clear stock, furniture or equipment away from the joints
  • Share the asbestos register for older buildings
  • Warn occupants and staff about the work

Related advice

Common problems we fix in Puttock's End

Some seals fail because the wrong product went in: expanding foam or a general-purpose sealant pushed into a gap to tidy it. It may look closed, but it has no tested fire performance in that position.

What tends to prompt an enquiry:

  • Service penetrations left open after M&E works
  • Unsealed penetrations discovered above suspended ceilings
  • Seals that don’t match their tested detail
  • Fire seals cut back for extra cables and never reinstated

In a school such as Takeley Primary School, fire-rated sealant goes in around service penetrations where it is specified.

Questions to ask before you book

  • Whether their applicators hold CSCS cards
  • Proof of insurance
  • Is the sealant right for the movement and the substrate?
  • Whether old or failed sealant will be cut out, not overlaid

Choosing a commercial sealant contractor

How the job changes by surface

Metal pipes

Sealant details often cover copper and steel pipework. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on and we confirm each before sealing.

Masonry and concrete

Many seals are made in blockwork, brickwork or concrete slabs. Dust and debris are cleared from the opening.

What we can’t put right

Being straight saves everyone time. Fresh joints won’t solve:

  • Deciding what a wall or floor needs, which belongs to the designer
  • Openings that need collars, wraps, batts or boards rather than sealant
  • Walls or floors that aren’t fire-resisting to begin with

If in doubt, phone 01277 525 020 or email a schedule or drawings and we will say what we think.

Surfaces we seal

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