Fire stopping in Brick End

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

When to call us in Brick End

Most open service penetrations are left by later work. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser leaves an opening that nobody returns to. Across several fit-outs, the openings add up.

Things that usually lead to an enquiry:

  • Fire stopping installed outside its tested range
  • Fire sealant pulled out of the opening
  • Non-fire-rated filler around services
  • Service penetrations left open after M&E works

Hotels like DeSalis Hotel, 1.4 miles to the west of Brick End, are refurbished in phases, and each phase can open up compartment walls.

How to choose a sealant contractor

Fire stopping in Brick End, done properly

A fire-rated sealant is only one part of a tested system: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. Before we seal anything, we check the opening against the detail it is meant to follow. If you’re dealing with fire sealant pulled out of the opening and non-fire-rated filler around services, we can help, on joints between fire-resisting walls and floors, small duct penetrations where the tested detail allows and pipe penetrations alike. Most enquiries from Brick End start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Around smaller places like Brick End, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Compartment walls and floors in Brick End

Brick End lies roughly 33 miles out from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls, and the gaps need sealing with the specified product. Fire stopping of openings and penetrations in England falls under Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.

Office fit-outs on sites such as Williams Field Business Centre (less than half a mile north of Brick End) add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it. Older community buildings such as Church of St Mary the Virgin that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Brick End is about 6 miles north-east of Bishop's Stortford, in Essex. We cover commercial sites throughout Brick End, for single jobs and planned programmes alike. Brick End is one of 644 places in Essex on our list. London is covered too, around 33 miles from Brick End.

How the job changes by surface

Small ducts

Some fire-rated sealant details cover small ducts. Bigger ducts and fire-resisting ductwork are normally handled with other products, and we will say if that applies.

Metal pipes

Copper and steel pipes are a common service penetration for fire-rated sealant. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail, so we check each one.

When something else is needed

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

  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Openings that need collars, wraps, batts or boards rather than sealant
  • Signing off or certifying a building’s fire stopping

If you are not sure, just ring 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.

What we seal

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

Quoting for work in Brick End

We price every job individually. The things that drive the figure:

  • Removal of failed or old sealant
  • Quantities, in metres or numbers
  • Specialist products, such as fire-rated or hygienic sealants
  • The size and state of each joint

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

What we need to price the job

A few photos plus some basic facts will normally do. Please tell us:

  • How the joints are reached, and at what height
  • Asbestos survey details if the building is older
  • The type of building and who uses it
  • The site address and postcode

For a fixed quote, call 01277 525 020 or use the quote form with the site address and an outline of the work. You can also send details through our quote form.

Diagnose, treat, sign off

  2. We sort the openings by the detail each one needs.
  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. Completed areas are checked with you, with the records agreed when we quoted.
