Fire stopping across Gaskins

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Doing it in-house

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Fire stopping in Gaskins

We should be clear about what we do and don’t do. The designer, fire engineer or building control decides which fire stopping is required; sign-off sits with them too. What we bring is careful installation of the specified sealant, to the maker’s guidance on sites in Gaskins. Most enquiries involve fire stopping installed outside its tested range and non-fire-rated filler around services, on small duct penetrations where the tested detail allows, cable penetrations and linear gaps at wall heads. Looking for mastic applicators who cover Gaskins? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.

A job near Gaskins is typically planned around one visit, so send the specification and photos first. Design and sign-off belong to the designer or building control; we install what’s specified.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

What sealant work can’t fix

Some faults sit outside our scope, and we say so rather than covering them up:

  • Writing the fire-stopping specification
  • Fire risk assessments, a job for a competent assessor
  • Signing off or certifying a building’s fire stopping

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

Surfaces we seal

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

What sets the cost

What shapes the price:

  • Any access equipment needed
  • Location, for remote and island sites
  • Removal of failed or old sealant
  • Which sealant the job calls for

The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a quote when you are ready.

Details that help us quote

We can often quote from photographs and a few details. It helps to include:

  • Rough lengths or quantities, or drawings if you have them
  • Where the site is, with the postcode
  • The asbestos register, for older buildings
  • Access details, including height

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Signs you need fire stopping in Gaskins

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.

Most enquiries start with one or more of the following:

  • Open linear gaps along the top of fire-resisting walls
  • Service penetrations left open after M&E works
  • Seals that don’t match their tested detail
  • Expanding foam used as fire stopping

On a site such as Ryde Business Park, which lies north-west of Gaskins, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product.

  • Health and safety accreditation such as CHAS
  • Their public liability cover
  • Do they follow the manufacturer’s priming guidance?

Questions to ask before you appoint anyone

Your questions answered

Can work in a care setting near Gaskins go ahead while residents are there?

Yes, with the manager deciding the order and timing of rooms. Noise and disruption are kept to a minimum.

Can you work on a hospital site such as Arthur Webster Memorial Hospital for Children?

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.

What does an EI 60 rating mean?

In short, BS EN 1366-3 and 1366-4 are the fire tests and BS EN 13501-2 is how results are classified. An EI 60 seal kept its integrity and insulation for 60 minutes as tested.

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

Do you offer coloured sealant?

It depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

Do you certify or sign off fire stopping?

No. We don’t certify or sign off fire stopping, and we hold no third-party fire-stopping installer certificate. We work to the specification and the manufacturer’s installation guidance, and any records you need can be confirmed with the quote.

Do you hold third-party fire-stopping installer certification?

No. We are not members of a third-party fire-stopping installer scheme. Our credentials are CHAS accreditation, Constructionline membership and CSCS-carded applicators, and we are fully insured. If your contract requires third-party installer certification, we are not the right fit for that package.

On site: what to expect

We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Smaller jobs around Gaskins can be grouped with others nearby. You’ll have a fixed quote before work starts.

  1. We read the specification, drawings or penetration schedule you send.
  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. We fit the backing the detail asks for, to the stated depth.
  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.

Preparing the site

  • Confirm the product named in the specification
  • Tell staff and tenants when we will be in
  • Move anything stored against the joints

Advice

Compartments and services around Gaskins

The 2 miles around Gaskins include two care or nursing homes. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal. In England, Approved Document B covers fire stopping of openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.

Wherever services are added at a hospital such as Arthur Webster Memorial Hospital for Children (to the south-west of Gaskins) the compartment line has to be made good with the specified product. In a building such as St Catherine-by-the-Green, any service penetration through a fire-resisting wall should be sealed to the specified detail.

How the job changes by surface

Drylining partitions

Plasterboard partitions are tested as a specific construction. We check that the product’s detail covers that partition type and board thickness before sealing.

Plastic pipes

In a fire, plastic pipework melts away and leaves an opening. Some intumescent sealants are tested on smaller plastic pipes. We check the pipe material and diameter against the detail before we start.
