Fire stopping near Hangleton

What the job involves on each surface

Small ducts

Some fire-rated sealant details cover small ducts. Larger or fire-rated ductwork normally needs a different solution set by the designer and we flag that rather than guess.

Masonry and concrete

Many seals are made in blockwork, brickwork or concrete slabs. Dust and debris are cleared from the opening, with backing added if the detail requires it.

How we handle fire stopping in Hangleton

Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Other openings need collars, wraps, batts, pillows or boards. We use sealant where it is the specified product, and we tell you when a detail calls for something else. The enquiries we see most involve unsealed joints where partitions meet the slab and fire stopping installed outside its tested range, on service gaps in risers, joints between fire-resisting walls and floors and cable penetrations. One point of contact handles commercial sealant work in Hangleton from the first photos to the final walk-round, whether it’s one building or several.

Smaller places such as Hangleton still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.

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

Doing it in-house

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

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 easy to get wrong without experience.

Can you seal penetrations in a hotel in Hangleton after a refit?

Yes. We install fire-rated and intumescent sealant where it is specified. Each seal follows the tested detail, and rooms are done in turn.

Do you cover Hangleton?

Yes. Hangleton is in our area, within our coverage of Greater London, South East England and Scotland. To discuss a job, call 01277 525 020 or email drawings and photos.

What happens if old sealant might contain asbestos?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

Do you seal on top of existing sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

How soon can the area be used again?

We’ll confirm how long the chosen product needs to cure.

Will your applicators have CSCS cards?

Yes. Our applicators hold CSCS cards, which many sites require.

Fire stopping around Hangleton: how the place shapes the job

At about 49 miles from central London, Hangleton is within reach of the capital. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls; the gaps need the specified seal. 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. We install whatever has been specified, to the product’s tested detail.

At a healthcare site like Goring Hall Hospital, which lies south-east of Hangleton, new services through compartment walls are a constant, and each needs the specified seal. For a building at a site such as Goring Business Park, which lies east of Hangleton, a check of penetration seals after each fit-out is good practice.

Hangleton is about 2 miles west of Worthing, in West Sussex. Looking for fire stopping in Hangleton? We can help. We work across 373 places in West Sussex, large and small. We also cover Brighton, around 14 miles from Hangleton.

Our process

We follow your site rules from the start: signing in, inductions and any permit to work. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact. If others near Hangleton need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  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. 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.

Preparing the site

  • Share your working hours and any access restrictions
  • Tell staff and tenants when we will be in
  • Send asbestos survey details if the building is pre-2000

Getting a fixed quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Honest limits

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

  • Plastic pipes whose detail calls for a collar or wrap
  • Fire doors, dampers or other fire safety equipment
  • Deciding what a wall or floor needs, which belongs to the designer

If in doubt, give us a call on 01277 525 020 or email the details over and we’ll say what we think before you book.

Where we work in Hangleton

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

For managing agents and facilities managers

If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

Common problems we fix in Hangleton

Mixing products or improvising a detail breaks the link with the test evidence. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are the usual culprits.

Look out for the following:

  • Damaged fire seals in risers and voids
  • Fire sealant pulled out of the opening
  • Unsealed openings around new pipes and cables
  • Head-of-wall gaps with no fire seal

Hotels like Angmering Manor Hotel (to the north-west of Hangleton) are refurbished in phases, and each phase can open up compartment walls.
