Fire stopping for commercial buildings in Arlington

A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind. Those on your schedule are closed with the specified product. If you’re dealing with expanding foam used as fire stopping and seals disturbed by maintenance and left open, we can put it right, on service gaps in risers, linear gaps at wall heads and cable penetrations alike. A specialist sealant contractor works differently from a general builder: on jobs in Arlington, preparation and product choice get the time they need.

Barn and farm-building conversions near places like Arlington often combine new partitions with old walls. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application.

Honest limits

A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:

  • Reviewing a building’s overall fire safety
  • Walls or floors that aren’t fire-resisting to begin with
  • Large openings beyond what any sealant detail covers

If you are not sure, just speak to us on 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.

What we seal

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

Fire-rated sealing for Arlington buildings

For England, the fire stopping of penetrations is dealt with in Approved Document B. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. We install whatever has been specified, to the product’s tested detail. Arlington lies roughly 47 miles out from central London. 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.

Offices at parks like Berwick Court Farm Business Park, 2.2 miles south-west of Arlington, are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail. Older community buildings such as The Parish Church of St Pancras that have been rewired or given new heating can have service gaps through walls worth checking against the specification. Large healthcare estates like Hellingly Hospital Railway, 4.1 miles to the north-east of Arlington, change their services often, so penetration seals are worth checking after M&E work.

Arlington is about 3 miles south-west of Hailsham, in East Sussex. If you are looking for fire stopping in Arlington, we can help. We work across 308 places in East Sussex, large and small. There’s a separate page for Brighton, about 14 miles away.

What the job involves on each surface

Metal pipes

Heat travels along metal pipework, and the tested detail may ask for insulation beyond the wall. We follow whatever the detail requires and flag anything we can’t match.

Drylining partitions

Holes in board are often cut larger than needed. An oversized hole may be outside the sealant’s range and we will tell you what the detail says instead.

Diagnose, treat, sign off

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Jobs in and around smaller places like Arlington are usually planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. The specification and schedule come first, so we know which details apply.
  2. Access, permits and the order of areas are agreed with the site team.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Unsuitable material is removed and the opening cleaned so the seal starts clean.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. Anything outside the detail is reported to you rather than sealed.

Before we start on site

Advice

Site staff or a sealant specialist?

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Building owners, agents and FMs in Arlington

Building owners and managing agents use us on everything from one building to a spread of sites around Arlington. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

Questions about Arlington

Is Arlington too small for you to travel to?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.

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

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.

How many days will you need on site?

The duration is planned around your programme and the access we are given. You will have an expected duration with the quote.

Is colour matching possible?

That depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

How do I request a quote?

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

When can you be on site?

We’re in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.

Are you CHAS accredited?

Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

Why act early in Arlington

Fire stopping is a regular point raised at inspections and handover. Late discoveries can delay handover while openings are reopened and resealed, so earlier action pays back. Converted and older buildings near places like Arlington tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Why us?

  • Work to your specification and the manufacturer’s guidance
  • CSCS-carded applicators
  • One phone line for London, the South East and Scotland
  • Workmanship guaranteed for 12 months
