Fire stopping in Iwade

Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. 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. Most enquiries involve openings left by services added after handover and builders’ foam or ordinary silicone in compartment walls, on service gaps in risers, small duct penetrations where the tested detail allows and cable penetrations. For commercial sealant work in Iwade, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Around Iwade, penetration and linear seals tend to be one-building jobs. With the specification and photographs of the gaps, we can give a fixed quote and bring the right products.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

When to bring in a specialist

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.

Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.

On site: what to expect

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Several jobs near Iwade can be grouped on one trip. Mention the building’s opening times and we will work within them.

  1. We start with your penetration schedule, drawings or specification.
  2. We plan the sequence of floors, risers and voids with you.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Unsuitable material is removed and the opening cleaned.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

Before we start on site

  • For older buildings, check the asbestos register before work
  • Send your site hours and access windows
  • Explain the parking and delivery arrangements

Surface by surface

Linear joints

Joints at the top of partitions may need to move as the slab above deflects. We use the product and backing the detail names for that movement.

Drylining partitions

Holes in board are often cut larger than needed. If the gap exceeds the tested range, sealant alone won’t do.

Honest limits

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

  • Fire doors, dampers or other fire safety equipment
  • Issuing fire ratings or certificates for seals
  • Openings that need collars, wraps, batts or boards rather than sealant

Not sure which it is? You can call 01277 525 020 or email us and we will tell you honestly.

Joints and surfaces we work on

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

Your questions answered

Can work at a site such as KITE College fit around teaching?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Let us know which documents your site asks for, and we will confirm them alongside the quote.

How does the move away from BS 476 affect penetration seals in Iwade?

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.

How soon can the area be used again?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

Can you work while the building is occupied?

Yes, as long as we plan it. Tell us your site hours and access windows and we will plan around them.

What if there’s asbestos in the old mastic?

Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

Is your workmanship covered by a guarantee?

Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.

When can you be on site?

Mention the site’s hours and access windows in your enquiry, and we will plan around them. You can reach the office between 8am and 5pm, Monday to Friday.

Looking after the joints

Problems stay small when the joints are checked regularly. Specifically:

  • Leave fire sealant to cure fully before covering it
  • Brief every trade that openings they make must be sealed
  • Agree the fire-stopping specification before services go in
  • Look above ceilings when tiles are lifted for other jobs

Store the specified product details somewhere the next contractor can find them. It makes later repairs much easier to match.

Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job compared with dozens found at once.

Fire stopping around Iwade: points for this area

Iwade is about 36 miles from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls. In England, Approved Document B covers fire stopping of openings and penetrations. 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.

On a hospital site such as Sittingbourne Memorial Hospital, which lies south of Iwade, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits. In a school such as Iwade School, fire-rated sealant goes in around service penetrations where it is specified. Workshops and IT rooms at colleges like KITE College, 2.3 miles south of Iwade, are re-serviced often, leaving penetrations to seal.
