Fire stopping for businesses in Morestead

Fire stopping in Morestead, 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 and the specified product data. Tell us what records you need and we’ll confirm with the quote. We work on small duct penetrations where the tested detail allows, service gaps in risers and linear gaps at wall heads, and the usual reasons a site gets in touch are penetration schedules that need working through and fire seals cut back for extra cables and never reinstated. Whether you call it commercial sealant work, mastic application or joint sealing, in Morestead it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Around smaller places like Morestead, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

When something else is needed

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Construction that lacks the fire resistance the seal relies on
  • Approving the work on behalf of building control
  • Reviewing a building’s overall fire safety

If in doubt, give us a call on 01277 525 020 or email drawings and photos and we’ll say what we think before you book.

Surfaces we seal

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

Compartment walls and floors in Morestead

Fire stopping of openings and penetrations in England falls under Approved Document B. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. Either way, we install the specified product to its tested detail. At about 60 miles from central London, Morestead is within reach of the capital. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.

Hospital estates such as Leigh House Hospital, 2.3 miles to the north of Morestead, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. Campus buildings at universities such as University of Winchester, 3.2 miles north-west of Morestead, see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified. Tenant changes at parks like Hazeley Enterprise Park (to the west of Morestead) bring new data and services, and openings through fire-resisting walls need the specified seal.

Cost factors for service penetrations

Your fixed quote is built from the real scope. It allows for:

  • The product specified
  • How accessible the joints are
  • Distance, for remote addresses
  • How much existing material needs removing

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Before you send an enquiry

Whether it’s one area or a whole building, the same details help:

  • Clear photos of the problem areas
  • What the building is and how it’s used
  • The postcode of the building
  • Access details, including height

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.

Looking after the joints

After handover, a little attention goes a long way:

  • Include service cupboards in routine inspections
  • Settle who seals which penetrations at the start of a project
  • Flag new cables with no seal around them
  • Keep product data and details in the fire safety file

During planned inspections, look at seals in risers, cupboards and voids. Watch for cracked sealant, new services with no seal and openings that have grown and get them dealt with.

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.

How a job runs

Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. If others near Morestead need work, visits can be combined. A fixed quote is given before anything 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. Mineral wool or other backing is fitted where required.
  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.

What we need from you

  • Confirm the product named in the specification
  • Tell us your opening times and when work is allowed
  • Move anything stored against the joints

How the job changes by surface

Masonry and concrete

Many seals are made in blockwork, brickwork or concrete slabs. Dust and debris are cleared from the opening, so the sealant and any backing sit properly.

Linear joints

Head-of-wall gaps, slab edges and wall junctions are linear joints. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed.

FAQs: Morestead

Can you work at a site such as Hazeley Enterprise Park, by Morestead?

Yes, sites like Hazeley Enterprise Park are within our area, along with the rest of Morestead. Photos and a short description are enough for a first look.

Is a hospital such as Leigh House Hospital somewhere you can work?

Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.

Who decides which product is used?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Which standards are fire seals tested to?

BS EN 1366-3 covers penetration seals and BS EN 1366-4 covers linear joints. Results are classified under BS EN 13501-2. That rating only holds when the product is installed to its tested detail.

Does the weather affect the work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Can you fire stop behind the services contractors?

Yes, where there is a specification for those walls and floors. Openings left by new services are among the most common jobs we see and we close them with the specified product.

Can you work to our specification?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.

Leave it or put it right?

Open penetrations multiply: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable and avoids a much larger catch-up later. Halls, stores and units around places like Morestead may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

Pricing service penetrations depends on quantities, condition and access, and any specification that applies. Call for a quote.
