Fire stopping in Westdene

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Diagnose, treat, sign off

Tell us your site hours and access windows and we will plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. Work in places the size of Westdene is planned as a single visit where we can. Clear photos and measurements help us bring the right products.

  1. First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. We fit the backing the detail asks for, to the stated depth.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

What we need from you

  • Tell us what induction or permit system the site runs
  • Confirm the product named in the specification
  • Make sure the joints can be reached

Ask for a quote

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

Advice

Fire stopping in Westdene

Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We don’t hold a third-party fire-stopping installer certificate. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. We work on pipe penetrations, cable penetrations and small duct penetrations where the tested detail allows, and what we’re called in for most is fire-stopping items raised at inspection or handover and unsealed penetrations discovered above suspended ceilings. Most enquiries from Westdene start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Fire-rated sealing in a place like Westdene is usually a single building at a time. Send the specification, drawings or photos of the openings and we will quote to suit.

Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

When something else is needed

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Writing the fire-stopping specification
  • Fire risk assessments, a job for a competent assessor
  • Approving the work on behalf of building control

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

What we seal

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

Questions about Westdene

Can you work in a care home near Westdene with residents in?

Yes. Care settings are planned area by area, at times agreed with the home. We follow the home’s own procedures throughout.

Do you work on fire-rated sealing in hotels in Westdene?

Yes, where the specification calls for fire-rated sealant. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we’ll tell you if the detail calls for a collar, wrap or batt instead.

Can you send site paperwork?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

Do you cover Westdene?

Yes. Sites across Westdene are covered.

How much does the work cost?

We don’t publish prices, because every site is different. With photographs or drawings, we can give you a fixed quote.

How long does a typical visit take?

We plan the time on site around your programme and access. You’ll have an expected duration with the quote.

Will you just go over the old sealant?

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

What the job involves on each surface

Cables and cable bundles

Single cables and small bundles are often within a fire-rated sealant’s tested detail. The detail limits bundle size and the gaps between and around cables and we work within those limits.

Risers and ceiling voids

Voids hide a lot of unsealed openings. We follow your schedule area by area and tell you about openings outside the list.

Compartment walls and floors in Westdene

There are a number of hotels within about 2 miles of Westdene. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. There are four care or nursing homes within about 2 miles of Westdene. In a care home, any new pipe or cable through a fire-resisting wall should be sealed to the specified detail. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail.

Refits at places like Goldstone Retail Park, 1.6 miles to the south of Westdene, often reroute services through walls between units. Wherever services are added at a hospital such as Mill View Hospital (1.7 miles south-west of Westdene) the compartment line has to be made good with the specified product. Hotels like Preston Park Hotel (1 mile south-east of Westdene) are refurbished in phases, and each phase can open up compartment walls.

Work for main contractors and building owners

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Westdene can form part of a wider programme.

Maintenance after handover

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Arrange inspection before areas are covered up
  • Ask the designer to confirm details early on refits
  • Keep product data and details in the fire safety file
  • Leave fire sealant to cure fully before covering it

Store the specified product details somewhere the next contractor can find them. Anyone resealing later needs to know which product and detail were used.

Keep a register of where seals are and what they are made of. When a new service goes through, everyone knows which product and detail to match, and it helps at inspections.

What sets the cost

Sealant work doesn’t have a standard rate, because every site is different. What we look at:

  • Which sealant the job calls for
  • Induction, permit and paperwork requirements
  • The size and state of each joint
  • Distance, for remote addresses

The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site rules also count.

What to include in your enquiry

It doesn’t need to be a full survey. A few details are enough to get going:

  • What the building is and how it’s used
  • Photos of the joints, close up and from further back
  • Drawings or a marked-up plan, if available
  • Anything awkward about access or site hours
