How we handle fire stopping in Adur

It helps to set out our role at the start. The designer, fire engineer or building control decides which fire stopping is required. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance. If you have old intumescent sealant that has split away and unsealed penetrations discovered above suspended ceilings, we can help. For commercial sealant work in Adur, you deal with one contact from quote to sign-off, whether it’s one building or several.

For a smaller site near Adur, we plan to do all the penetrations in one go, with the specification and photographs sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.

Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Cost factors for service penetrations

Quotes vary with the job. Expect it to depend on:

  • Site requirements such as inductions and permits
  • Joint width, depth and condition
  • How much there is to seal
  • The product specified

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

What we need to price the job

Whether it’s one area or a whole building, the same details help:

  • Photos of the joints, close up and from further back
  • Approximate linear metres or a joint schedule
  • Any specification or named product
  • What the building is and how it’s used

To get a fixed quote, ring 01277 525 020 or email a schedule or drawings with the site address and an outline of the work. You can also send details through our quote form.

FAQs: Adur

Would you work within a site like Southlands Hospital?

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

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

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

How do I request a quote?

There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.

How do you choose the sealant?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Can the building stay open while you work?

Yes, with some planning. Tell us your site hours and access windows and we will plan around them.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

Do you take on small jobs?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

Why it’s worth doing now in Adur

Sealing behind the M&E trades area by area beats a sweep at the end. While the area is still open, every opening is easy to see and reach, and the right detail can be checked at the time. Converted and older buildings near places like Adur tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Why us?

  • Fully insured
  • Commercial sealant work since 2005
  • CSCS-carded applicators
  • A Constructionline member, so easy to vet

Take a look at how commercial sealant jobs are priced or how we’re accredited.

Should maintenance staff do it?

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

How a job runs

At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. Rural sites near Adur may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. First we go through the drawings, schedule or specification for the seals.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  4. Mineral wool or other backing goes in wherever the detail asks.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

What we need from you

  • Point out parking and an unloading spot
  • Let building users know which areas are affected
  • Send your site hours and access windows

Different surfaces, different methods

Metal pipes

Metal pipes conduct heat, so their details often call for extra measures along the pipe, and the tested detail may ask for insulation beyond the wall. We follow whatever the detail requires and flag anything we can’t match.

Plastic pipes

Plastic pipes soften and collapse in a fire. Small sizes are sometimes covered by an intumescent sealant detail. We check the pipe material and diameter against the detail before we start.

Compartments and services around Adur

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. Either way, we install the specified product to its tested detail. Central London is about 45 miles from Adur. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls; the gaps need the specified seal.

On estates like Dolphin Industrial Estate, 2 miles to the south-east of Adur, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal. In a school such as The Sir Robert Woodard Academy, fire-rated sealant goes in around service penetrations where it is specified.

Adur is about 1 mile north-west of Shoreham-by-Sea, in West Sussex. Businesses, contractors and managing agents in Adur use us for work on service penetrations. Our West Sussex coverage takes in 373 places. We also cover Brighton, some 7 miles away.

Do you need fire stopping in Adur?

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

Site and facilities staff are often the first to spot these:

  • Unsealed penetrations discovered above suspended ceilings
  • Penetration schedules that need working through
  • Seals disturbed by maintenance and left open
  • Builders’ foam or ordinary silicone in compartment walls

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

What your quote should include

  • Proof of insurance
  • Whether primer will be used where the manufacturer specifies it
  • Can the work be phased to keep areas open?
  • How the existing material will be dealt with
