Fire stopping in South Mundham

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

Fire stopping in South Mundham

Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We hold no third-party fire-stopping installer certificate and we’d rather say that up front. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. If you have fire sealant pulled out of the opening and expanding foam used as fire stopping, we can help, on small duct penetrations where the tested detail allows, pipe penetrations and service gaps in risers alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in South Mundham, preparation and product choice get the time they need.

Rural conversions around South Mundham 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.

The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Fire stopping in South Mundham: the local picture

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. Our part stays the same: the specified product, installed to its tested detail. At about 56 miles from central London, South Mundham 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, and the gaps need sealing with the specified product.

Residences at universities like University of Chichester (to the north-east of South Mundham) have compartment walls that must be resealed whenever services change. For a unit at a site such as Quarry Lane Industrial Estate, which lies north of South Mundham, new power or data runs between office and warehouse can breach a compartment wall.

South Mundham is about 3 miles south of Chichester, in West Sussex. We cover South Mundham, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. South Mundham is one of 373 places in West Sussex on our list. Sites around Portsmouth have their own page, about 14 miles away.

Commercial sites across PO20 are covered for service penetrations. Among the streets we cover are Manor Lane and Honer Lane. Sites close to South Mundham are covered too, including Fisher (1 mile west), Street End (2 miles south-west), Sidlesham Common (2 miles west), Nyetimber (2 miles south-east) and Sidlesham (2 miles south-west). Nearby towns on our patch include Bognor Regis (3 miles east), Chichester (3 miles north), Selsey (5 miles south), Littlehampton (10 miles east), Rustington (11 miles east) and Angmering (12 miles east).

Questions we are asked in South Mundham

Does your area include sites such as Quarry Lane Industrial Estate, near South Mundham?

Yes. Estates, retail parks and business parks around South Mundham, Quarry Lane Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.

Can work at a site such as University of Chichester fit around teaching?

Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Can weather delay the job?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

What’s the quickest route to a quote?

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

What changes on 2 September 2029?

From 2 September 2029, Approved Document B in England drops its references to BS 476 classes, subject to the Government’s transitional arrangements. The European route, BS EN 13501-2, then applies. Product selection stays with your designer.

Is colour matching possible?

It depends on the product. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.

Do you take on small jobs?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

When something else is needed

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

  • Approving the work on behalf of building control
  • Reviewing a building’s overall fire safety
  • Gaps in walls that were never built as compartment walls

Not sure which it is? You can ring 01277 525 020 or email the details over and we will tell you honestly before you book.

Joints and surfaces we work on

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

On site: what to expect

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. Jobs in and around smaller places like South Mundham are normally planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. First we confirm the product and tested details named in the specification.
  2. Openings are measured and grouped by detail.
  3. Old or wrong materials are cut out.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Before we start on site

  • Confirm the product named in the specification
  • Tell us which areas need to stay in use
  • Warn occupants and staff about the work

Quotes

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or email drawings and photos.

Should maintenance staff do it?

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

A short, simple internal joint is often within reach of a maintenance team. 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.

Common problems we fix in South Mundham

Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Deflection and building movement can open these gaps. The tested detail for a linear joint states the width and movement it covers.

Any of the following is a good reason to get the joints checked over:

  • Fire sealant pulled out of the opening
  • Fire-stopping items raised at inspection or handover
  • Non-fire-rated filler around services
  • Seals disturbed by maintenance and left open

For a site team at a college like West Sussex Alternative Provision College, which lies north of South Mundham, fire-rated sealing is best scheduled after the summer works.

Comparing quotes

  • Whether their applicators hold CSCS cards
  • Whether old or failed sealant will be cut out, not overlaid
  • Can the work be phased to keep areas open?
  • How long is the guarantee, and what does it include?

How to choose a sealant contractor

What the job involves on each surface

Metal pipes

Metal pipes conduct heat, so their details often call for extra measures along the pipe. If the detail needs something beyond sealant, we tell you.

Plastic pipes

Waste and drainage pipes through floors are a frequent case. The detail decides whether sealant alone is enough.

How the quote is worked out

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

  • Travel to remote or island sites
  • Any access equipment needed
  • Which sealant the job calls for
  • The total length or number of joints

The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

What to include in your enquiry

A good diagnosis starts with the right details. Let us know:

  • Specification clauses that apply
  • Access details, including height
  • A wide shot and a close-up of the area
  • Whether an asbestos survey exists

A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or call 01277 525 020 or email drawings and photos to discuss it first.
