Need fire stopping in East Hampnett?

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

Our process

We begin with a short walk round with whoever looks after the building, 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. For work around East Hampnett, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.

  1. First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. We fit the backing the detail asks for, to the stated depth.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

What we need from you

  • Arrange parking or a loading space
  • Let building users know which areas are affected
  • Tell us your opening times and when work is allowed

How we handle fire stopping in East Hampnett

Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4, with results classified under BS EN 13501-2. A rating such as EI 60 only holds when the product is installed as it was tested. So our job is to reproduce that arrangement faithfully. If you’re dealing with openings left by services added after handover and builders’ foam or ordinary silicone in compartment walls, we can put it right. Facilities teams, main contractors and managing agents in East Hampnett tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Rural conversions around East Hampnett can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Looking after the joints

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:

  • Have penetrations checked while they can still be seen
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Flag new cables with no seal around them
  • Leave fire sealant to cure fully before covering it

After every round of M&E works, check that the openings created have been sealed. Building it into each contractor’s sign-off keeps the walls intact.

Write fire stopping into the scope of any work crossing a compartment wall or floor. That way the opening is sealed while the trade and access are still there.

What sealant work can’t fix

Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:

  • Approving the work on behalf of building control
  • Deciding what a wall or floor needs, which belongs to the designer
  • Walls or floors that aren’t fire-resisting to begin with

If in doubt, speak to us on 01277 525 020 or use the quote form and we will say what we think.

What we seal

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

Questions we’re asked in East Hampnett

What does the BS 476 change mean for fire-rated sealant in East Hampnett?

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.

Why it’s worth doing now in East Hampnett

The longer openings stay, the more there tend to be: each new service adds to the list. Keeping on top of it after each round of works keeps the job small, rather than turning into a full building survey and reseal. For buildings around smaller places like East Hampnett, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Why clients in East Hampnett choose us

  • One number for every site we cover

A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. At about 52 miles from central London, East Hampnett is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls, and the gaps need sealing with the specified product.

Holiday works at schools like Tangmere Primary Academy often leave service openings to seal before pupils return. Campus buildings at universities such as University of Chichester, 2.6 miles south-west of East Hampnett, see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified.

When to bring in a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
