Fire stopping across North Gorley

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

Fire stopping in North Gorley, done properly

For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. We work from your penetration schedule or marked-up drawings. Tell us what records you need and we’ll confirm with the quote. Most enquiries involve unsealed penetrations discovered above suspended ceilings and fire seals cut back for extra cables and never reinstated, across small duct penetrations where the tested detail allows, linear gaps at wall heads and pipe penetrations. A specialist sealant contractor works differently from a general builder: on jobs in North Gorley, preparation and product choice get the time they need.

Smaller places such as North Gorley still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.

Work we carry out comes with a 12-month guarantee. If an installation problem shows up, give us a call on 01277 525 020 or email the details over and we will arrange a return visit.

Doing it in-house

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

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.

What we’re called out for in North Gorley

Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Movement in the frame or slab can open the joint, and the wrong product can split as a result. The tested detail for a linear joint states the width and movement it covers.

Common reasons buildings call us in:

  • Old intumescent sealant that has split away
  • Non-fire-rated filler around services
  • Fire stopping installed outside its tested range
  • Openings found when ceilings come down for a refit

Offices at parks like Fordingbridge Business Park (to the north-west of North Gorley) are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail.

Questions to ask before you book

  • Is the sealant right for the movement and the substrate?
  • The terms of the workmanship guarantee
  • Will CSCS-carded applicators be on site?
  • Whether old or failed sealant will be cut out, not overlaid

How to choose a sealant contractor

Honest limits

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Approving the work on behalf of building control
  • Construction that lacks the fire resistance the seal relies on
  • Writing the fire-stopping specification

Not sure which it is? You can call 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.

Joints and surfaces we work on

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

What affects the price in North Gorley

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

  • Joint width, depth and condition
  • Distance, for remote addresses
  • Whether old sealant has to be cut out first
  • The product specified

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

What to include in your enquiry

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

  • Asbestos survey details if the building is older
  • Anything awkward about access or site hours
  • Where the site is, with the postcode
  • When you need the work done

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

How a job runs

Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. If others near North Gorley need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.

  1. We ask for the product and detail your designer has specified.
  2. We sort the openings by the detail each one needs.
  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. Completed areas are checked with you, with the records agreed when we quoted.

Getting the site ready

  • Confirm the product named in the specification
  • Share the asbestos register for older buildings
  • Agree which areas must stay open

Your questions answered

Is North Gorley too small for you to travel to?

Not at all. North Gorley is within our area. London and every South East county are within our area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Is hospital work, at somewhere like Fordingbridge Hospital, something you do?

Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Will you sign off the seals for us?

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 have third-party installer accreditation for fire stopping?

No. We don’t hold a third-party fire-stopping installer certificate. We are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded. If your contract requires third-party installer certification, we are not the right fit for that package.

Is your workmanship covered by a guarantee?

Yes. Our workmanship is backed for 12 months on every job.

How soon can the area be used again?

Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.

Which standards are fire seals tested to?

Penetration seals are tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. Classification follows BS EN 13501-2, where E is integrity, I is insulation and the number is minutes, as in EI 60. That rating only holds when the product is installed to its tested detail.

Where services cross fire walls in North Gorley

Fire stopping of openings and penetrations in England falls under Approved Document B. 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. Our part stays the same: the specified product, installed to its tested detail.

Halls and meeting rooms at places like Church of the Holy Ascension sometimes gain new services, and any compartment wall crossed needs the specified seal. Theatres, wards and plant rooms at sites like Fordingbridge Hospital (to the north-west of North Gorley) all have compartment walls crossed by services.
