Fire stopping for South Nutfield sites

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

How we handle fire stopping in South Nutfield

For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, call 01277 525 020 or use the quote form with the schedule or marked-up drawings and the specified product data. Tell us what records you need and we’ll confirm with the quote. The enquiries we see most involve expanding foam used as fire stopping and fire seals cut back for extra cables and never reinstated, across linear gaps at wall heads, cable penetrations and small duct penetrations where the tested detail allows. Whether you call it commercial sealant work, mastic application or joint sealing, in South Nutfield it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Smaller places such as South Nutfield still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

Work we carry out in Surrey comes with a 12-month guarantee. If an installation problem shows up, ring 01277 525 020 or email drawings and photos and we’ll arrange a return visit.

Diagnose, treat, sign off

At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. For work around South Nutfield, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. First we confirm the product and tested details named in the specification.
  2. Openings are measured and grouped by detail.
  3. Old or wrong materials are cut out.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Getting the site ready

  • Have the specification and drawings to hand
  • Send your site hours and access windows
  • Let building users know which areas are affected

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

What we can’t put right

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

  • Approving the work on behalf of building control
  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Large openings beyond what any sealant detail covers

If in doubt, call the office on 01277 525 020 or email a schedule or drawings and we’ll say what we think.

Joints and surfaces we work on

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

Compartments and services around South Nutfield

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. The area within 2 miles of South Nutfield holds a number of hotels. In hotels, bedroom and corridor walls are normally fire-resisting, so services added in a refit need sealing with the specified product.

Schools such as Nutfield Church CofE Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. Office fit-outs on sites such as Kingsfield Business Centre (1.5 miles west of South Nutfield) add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it. For a hospital such as East Surrey Hospital, which lies west of South Nutfield, penetration sealing is normally phased ward by ward, with infection-control rules agreed first.

Work for main contractors and building owners

Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.

If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.

What sets the cost

A fixed quote reflects the actual work. It allows for:

  • Location, for remote and island sites
  • The site’s rules and procedures
  • How accessible the joints are
  • Backing rod, priming and other preparation

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

Sending details for a quote

To price the job accurately, we need to understand the site. Useful things to include:

  • Specification clauses that apply
  • Clear photographs of the problem areas
  • What the building is and how it’s used
  • Approximate linear metres or a joint schedule

Need a figure for a tender or a budget? We will quote against your scope and drawings you can plan around. If you have questions first, ring 01277 525 020 or send details through our quote form.

Different surfaces, different methods

Cables and cable bundles

Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. Bundle size, cable type and the space between cables all matter.

Small ducts

We seal around ducts only within what the tested detail covers. Dampers and ductwork systems themselves are outside our work.

Site staff or a sealant specialist?

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Redoing a failed joint normally costs more than getting it right at the outset, 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.

Questions we’re asked in South Nutfield

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

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Do you work on fire-rated sealing in hotels in South Nutfield?

Yes, where fire-rated sealant is the specified product. We match the product to the wall or floor and the services, and say if something other than sealant is needed.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and the quote will be based on it.

Do your applicators hold CSCS cards?

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

Will you come and look before quoting?

Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.

Can staff carry on working while you’re here?

Yes, with some planning. Tell us your site hours and access windows and we’ll plan around them.

Is colour matching possible?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
