Fire stopping in Little Atherfield

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Cost factors for service penetrations

Quotes vary with the job. It mainly depends on:

  • Location, for remote and island sites
  • Quantities, in metres or numbers
  • The site’s rules and procedures
  • The size and state of each joint

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

What we need to price the job

Good information means a firmer quote. Helpful details to send:

  • A wide shot and a close-up of the area
  • The postcode of the building
  • Your programme or deadline
  • Any specification or named product

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.

About our fire stopping in Little Atherfield

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. If you are dealing with non-fire-rated filler around services and snag lists that include open service penetrations, we can help, whatever the surface. Most enquiries from Little Atherfield start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Around smaller places like Little Atherfield, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Should maintenance staff do it?

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Different surfaces, different methods

Metal pipes

Heat travels along metal pipework, and some details add wrapping or a set length of insulation. If the detail needs something beyond sealant, we tell you.

Small ducts

Some fire-rated sealant details cover small ducts. Bigger ducts and fire-resisting ductwork are normally handled with other products and we flag that rather than guess.

Leave it or put it right?

Inspections and handover checks often pick up fire stopping. Late discoveries can delay handover while openings are reopened and resealed, so earlier action pays back. Older rural buildings around Little Atherfield move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Why us?

  • Products installed to the manufacturer’s instructions
  • Fully insured, including public liability cover
  • Work carried out by CSCS-carded applicators
  • A fixed quote before work starts

Take a look at our cost guide and our accreditations and insurance.

Looking after the joints

For the best life from the joints:

  • Look above ceilings when tiles are lifted for other jobs
  • File the specified details where the next contractor can find them
  • Agree the fire-stopping specification before services go in
  • Make fire stopping part of every scope that crosses a fire-resisting wall

Keep the product data and installation details with the building’s fire safety information. It makes later repairs much easier to match.

On fit-outs, get the fire-stopping specification agreed before the services go in. Details can then be picked to suit the actual pipes, cables and ducts.

Your questions answered

What happens to BS 476 references for fire stopping in Little Atherfield?

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.

Can you take on a job at a hospital such as Whitecroft Hospital?

Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.

How do you deal with asbestos in old sealant?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

What’s the quickest route to a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.

When can you be on site?

Give us your site hours and any access windows in your enquiry, and we will plan around them. Our office runs Monday to Friday, 8am until 5pm.

Will your applicators have CSCS cards?

Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.

On site: what to expect

Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before we move to the next. For a building around Little Atherfield, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  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. Foam, ordinary sealant and debris come out so the seal starts clean.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. We tell you about openings that need a different product.

Preparing the site

  • Point out parking and an unloading spot
  • Agree which areas must stay open
  • Flag any permit to work we’ll need

Request a quote
