Questions about Little Milton

How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Little Milton?

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.

Will you take on work at estates like The Boundary Business Park, close to Little Milton?

Yes, sites like The Boundary Business Park are within our area, along with the rest of Little Milton. A few photographs and the unit address let us price the work.

What if there’s asbestos in the old mastic?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

Can staff carry on working while you are here?

In the majority of cases, yes. We phase the work so most of the building stays in use, with each area protected and signed.

How long will the new sealant last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

What’s the quickest route to a quote?

You can use the quote form on this site; alternatively, call 01277 525 020 or email us. Include photographs or drawings if you have them.

Is your workmanship covered by a guarantee?

Yes. It runs for twelve months and covers how we prepared and sealed the joints, but not damage, misuse or other trades’ work.

How we handle fire stopping in Little Milton

No fire sealant works on its own: 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, and we say so if it doesn’t fit. We work on service gaps in risers, cable penetrations and joints between fire-resisting walls and floors, and the failures we’re asked to look at most are old intumescent sealant that has split away and builders’ foam or ordinary silicone in compartment walls. Whoever orders the work in Little Milton, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

For a smaller site near Little Milton, we plan to do all the penetrations in one go, so send the specification and photos first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

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.

What happens if it’s left?

An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. While the openings can be reached, sealing them is normally straightforward. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. Older rural buildings around Little Milton move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

  • Joints cleaned back to sound surfaces
  • A fixed quote before work starts

What sealant work can’t fix

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Issuing fire ratings or certificates for seals
  • Large openings beyond what any sealant detail covers
  • Gaps in walls that were never built as compartment walls

Not sure which it is? You can call 01277 525 020 or send details through our quote form and we’ll tell you honestly before you book.

Where we work in Little Milton

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

What we’re called out for in Little Milton

Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is how unsuitable products and improvised details end up in compartment walls and later need putting right.

What tends to prompt an enquiry:

  • Penetration schedules that need working through
  • Fire-rated sealant that has cracked or shrunk back
  • Seals that don’t match their tested detail
  • Unsealed penetrations discovered above suspended ceilings

In a building such as Church of St James, any service penetration through a fire-resisting wall should be sealed to the specified detail.

Questions to ask before you book

  • What the guarantee covers, and for how long
  • How the joint faces will be prepared and primed
  • Whether their applicators hold CSCS cards
  • Is the sealant right for the movement and the substrate?

Service penetrations in Little Milton buildings

For England, the fire stopping of penetrations is dealt with in Approved Document B. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. Central London is about 46 miles from Little Milton. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.

For a hospital such as NHS Oxfordshire Clinical Commissioning Group, 4.9 miles to the north-west of Little Milton, penetration sealing is usually phased ward by ward, with infection-control rules agreed first. For a school such as Little Milton Church of England Primary School, penetration sealing fits best at the end of the summer works.

On site: what to expect

Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before the next one starts. Smaller jobs around Little Milton can be grouped with others nearby. You’ll have a fixed quote before work starts.

  1. First we go through the drawings, schedule or specification for the seals.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. Mineral wool or other backing goes in wherever the detail asks.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

What we need from you

  • Let us know about inductions and permits
  • Share your working hours and any access restrictions
  • Warn occupants and staff about the work

Advice

Looking after the joints

For the best life from the joints:

  • Don’t let anyone top up a fire seal with the wrong product
  • Brief every trade that openings they make must be sealed
  • Ask which product is in place before decorating
  • Settle who seals which penetrations at the start of a project

Never top up a fire seal with foam, ordinary silicone or filler. A repair should use the original product, installed the same way unless the designer specifies otherwise.

Specify fire stopping early on refits, not as an afterthought. Details can then be picked to suit the actual pipes, cables and ducts, and the work runs in step with the M&E.

Quoting for work in Little Milton

These are the things that shape the price:

  • Backing rod, priming and other preparation

  • The site’s rules and procedures

It doesn’t need to be a full survey. These details are enough to start:

  • Photos of the joints, close up and from further back
  • When you need the work done
